パイル布帛及びその製造方法Pile fabric and manufacturing method thereof
　本発明は、パイル繊維の毛抜けを抑制し、パイル布帛の柔軟性を高めたパイル布帛及びその製造方法に関する。 [Technical Field] The present invention relates to a pile fabric in which pile fibers are prevented from falling out and the flexibility of the pile fabric is increased, and a method for manufacturing the pile fabric.
　従来からパイル布帛は、イミテーションファー又はフェイクファー、ボア等の名称で毛皮に似せた外観の布帛として知られている。これらはパイル編物、パイル織物から作られる。編みパイルの場合は、主としてシールフライス機、スライバーニット機（丸編機）で編み立てられ、いずれもパイル繊維がカットされている。たて編機のダブルラッシェル機で編み立てる場合は、地組織をダブルで形成すると同時に地組織間に接結糸を絡ませて、接結糸の中間をカットすることにより編成される。製織法の場合は、ベルベット織機、モケット織機を使用して上下２枚の地組織とこの間に接結糸を絡ませ、上下の基布の間をナイフでカットすることにより、２枚の織物を同時に織り上げる。しかし、これらの織編物、特にハイパイル布帛等の編物は抜け毛が多いという問題がある。 Conventionally, a pile fabric is known as a fabric having an appearance resembling a fur under the names of imitation fur, fake fur, bore and the like. They are made from pile knitted fabrics and pile fabrics. In the case of a knitted pile, knitting is mainly performed by a seal milling machine and a sliver knit machine (circular knitting machine), and in both cases, pile fibers are cut. When knitting with a double raschel machine of a warp knitting machine, knitting is performed by forming the ground texture double and simultaneously tying the binding yarn between the ground textures and cutting the middle of the binding yarn. In the case of the weaving method, velvet looms and moquette looms are used to intertwine the upper and lower ground fabrics and the binding yarn between them, and the upper and lower base fabrics are cut with a knife so that the two fabrics can be made simultaneously. Weave. However, these woven and knitted fabrics, particularly knitted fabrics such as high pile fabrics, have a problem of having a lot of hair loss.
　パイル布帛の抜け毛を防止するため、パイル繊維に低融点繊維を混合する提案（特許文献１）、地組織を構成する地糸に低融点繊維を混合する提案（特許文献２～３）等がある。しかし、これらの提案はいずれも布帛全体を上記低融点繊維の融点以上の温度にて加熱するため、地組織全体又はパイル繊維も融着してしまい、粗硬な風合いになってしまうという問題がある。 There are proposals for mixing low-melting fibers with pile fibers (Patent Document 1), proposals for mixing low-melting fibers with ground yarns constituting the ground structure (Patent Documents 2 to 3), etc. . However, both of these proposals heat the entire fabric at a temperature equal to or higher than the melting point of the low-melting fiber, so that the entire ground texture or the pile fiber is also fused, resulting in a rough texture. is there.
　そこで、特許文献４では、特定の繊維を用いたパイル布帛において、裏面におけるパイル繊維の特定部分のみを融着させることにより、立毛面の風合いを損なわずにパイル繊維の毛抜けを防止したパイル布帛を提案した。 Therefore, in Patent Document 4, in a pile fabric using a specific fiber, only a specific portion of the pile fiber on the back surface is fused, thereby preventing the pile fiber from coming off without impairing the texture of the raised surface. Proposed.

As a result, the pile fiber on the back surface of the pile fabric has at least one selected from the group consisting of an amino-modified silicone softener, an epoxy-modified silicone softener, and a carboxyl-modified silicone softener with respect to 100 parts by weight of the pile fiber. It has been found that by applying 0.4 part by weight or more of the organically modified silicone softener, it is possible to improve the flexibility of the pile fabric while suppressing the hair loss of the pile fiber. Softeners (also referred to as softeners) usually impart flexibility, slipperiness, etc. to the surface of the fiber, but surprisingly in this application, certain softeners are applied to the pile fibers on the back of the pile fabric. It has been found that by attaching a predetermined amount to the pile fabric, the flexibility of the pile fabric can be improved while suppressing the hair loss of the pile fibers.
　本発明のパイル布帛は、地組織と、上記地組織を構成する地糸に絡みかつ上記地組織の表面に立毛するパイル繊維を含むパイル布帛である。上記パイル布帛としては、特に限定されないが、例えば、ハイパイル布帛、ボアパイル及びタフトカーペット等が挙げられる。毛抜けが生じやすいハイパイル布帛に特に好適である。ハイパイル布帛は、特に限定されないが、例えば、立毛部のパイル繊維の長さが１５～１００ｍｍであることが好ましい。 The pile fabric of the present invention is a pile fabric that includes a ground fabric and pile fibers that are entangled with the ground yarn constituting the ground texture and are raised on the surface of the ground texture. Although it does not specifically limit as said pile fabric, For example, a high pile fabric, a bore pile, a tuft carpet, etc. are mentioned. It is particularly suitable for a high pile fabric that is prone to hair loss. The high pile fabric is not particularly limited, but for example, the length of the pile fiber in the raised portion is preferably 15 to 100 mm.
　上記ハイパイル布帛は、パイル編物であり、地組織はメリヤスの地組織となる。詳細には、上記ハイパイル布帛は、メリヤスの地組織と、該地組織を構成する地糸に絡みつつ上記地組織の表面に立毛するパイル繊維とを含む。ハイパイル布帛の場合、地組織がメリヤスであるので、伸縮性に優れる組織を構成することができる。メリヤスは、一般に、１本又は２本以上の糸がループをつくり、そのループに引っかけて、次の新しいループをつくることを継続し、順次ループを平面状に連続させて布地を形成したものである。そして、糸がループをつくりながら左右に往復して平面状の布地を形成するか、らせん状に進行して筒状の布地を形成するか等により、横方向に進行していくものを横編みメリヤス、整然と配列した多数の各経（たて）糸がループをつくりながら、隣接する左右の経糸とループで連結されて布地を形成するものを経編みメリヤスという。また、横編みメリヤスには、平編み、ゴム編み、パール編み等の編み方があり、経編みメリヤスには、デンビー編み、コード編み、アトラス編み、鎖編み等の編み方がある。ハイパイル布帛の地組織の編み方としては、商品性、生産性の観点から、横編みメリヤスが好ましい。 The high pile fabric is a pile knitted fabric, and the ground organization is a knitted ground organization. Specifically, the high pile fabric includes a knitted fabric and pile fibers that are tangled with the ground yarn constituting the ground structure and are raised on the surface of the ground structure. In the case of a high pile fabric, since the ground structure is knitted, a structure having excellent stretchability can be formed. A knitted fabric is generally a fabric in which one or more yarns create a loop and continue to make the next new loop by hooking on the loop, and then making the loop continuous in a plane. is there. And weaving what goes in the horizontal direction, such as whether the yarn reciprocates left and right while forming a loop to form a flat fabric, or spirally to form a tubular fabric, etc. A knitted fabric is a warp knitted fabric in which a number of warp yarns arranged in an orderly manner are looped and connected to adjacent left and right warp yarns to form a fabric. In addition, flat knitting knitting methods include flat knitting, rubber knitting, pearl knitting and the like, and warp knitting knitting methods include denby knitting, cord knitting, atlas knitting, chain knitting and the like. As a method of knitting the ground structure of the high pile fabric, weft knitted fabric is preferable from the viewpoint of merchantability and productivity.
　本発明では、パイル繊維の地組織のメリヤスに対する配置としては、地組織のメリヤスを構成する地糸の各ループの全てにパイル繊維が絡むように配置しても良いし、メリヤスを構成する地糸の各ループのうち、ウェール方向及び／又はコース方向においてパイル繊維の絡んでいない部分を有するように配置しても良い。 In the present invention, the pile fibers may be arranged with respect to the knitted fabric of the ground structure so that the pile fibers may be entangled with all the loops of the ground yarn constituting the knitted fabric of the ground structure, or the ground yarn constituting the knitted fabric. Of these loops, the pile fibers may be arranged so as not to be entangled in the wale direction and / or the course direction.
　上記地組織を構成する繊維、すなわち地糸を構成する繊維としては、パイル繊維より軟化点が高い繊維であれば良く、特に限定はない。例えば、ポリエステル繊維やセルロース系繊維等が挙げられる。ポリエステル繊維としては、例えば、ポリエチレンテレフタレート等のポリエステル樹脂を含む樹脂組成物を紡糸して得られる合成繊維等が挙げられる。セルロース系繊維としては、例えば、コットン等が挙げられる。より効果的に、パイル繊維の毛抜けを抑制し、パイル布帛の柔軟性を高める観点から、地糸は、ポリエステル繊維糸であることが好ましい。 The fiber constituting the above ground structure, that is, the fiber constituting the ground yarn is not particularly limited as long as it has a higher softening point than the pile fiber. For example, a polyester fiber, a cellulosic fiber, etc. are mentioned. Examples of the polyester fiber include synthetic fibers obtained by spinning a resin composition containing a polyester resin such as polyethylene terephthalate. Examples of the cellulosic fiber include cotton. The ground yarn is preferably a polyester fiber yarn from the viewpoint of more effectively suppressing the hair loss of the pile fiber and increasing the flexibility of the pile fabric.
　パイル繊維は地組織を構成する繊維よりも軟化点が低く、地糸に絡んだパイル繊維のうち、地組織の裏面において地糸より外側に配置されているパイル繊維は一部又は全部が融着され、上記地組織の表面に立毛するパイル繊維は融着していない。この手段としては、特に限定されないが、パイル布帛の裏面側からパイル繊維の軟化点以上、かつ上記地組織を構成する繊維の軟化点未満の温度で熱圧着することが好ましい。 The pile fibers have a lower softening point than the fibers constituting the ground structure, and among the pile fibers entangled with the ground yarn, some or all of the pile fibers arranged outside the ground yarn on the back surface of the ground texture are fused. In addition, the pile fibers raised on the surface of the ground tissue are not fused. The means is not particularly limited, but it is preferable to perform thermocompression bonding at a temperature not lower than the softening point of the pile fiber and lower than the softening point of the fiber constituting the ground structure from the back side of the pile fabric.
　上記パイル繊維は、アクリル繊維及び／又はアクリル系繊維を含む。これにより、風合いに優れたパイル布帛が得られる。一般的には、熱可塑性繊維をパイル繊維として用い、該熱可塑性繊維の融点又は軟化点以上の温度でポリッシング加工を行うと、パイル布帛の表面のパイル繊維は焦げたり、溶融したりしてしまい、良好な外観と風合いを有するパイル布帛が得られない。また、熱可塑性繊維のガラス転移点以下の温度でポリッシング加工を行うと、パイル布帛の表面のパイル繊維の捲縮が伸びないため良好な外観と風合いを有するパイル布帛が得られない。これに対し、アクリル繊維及びアクリル系繊維の捲縮は融点未満の温度でも伸びる。そして、アクリル繊維及びアクリル系繊維のガラス転移点は約１００℃、軟化点は約１５０～２３０℃であることから、パイル繊維にアクリル繊維及び／又はアクリル系繊維を用いる場合、ガラス転移点以上、軟化点以下の温度、例えば１００～１５０℃でポリッシング加工を行うことができる。さらに、アクリル繊維及びアクリル系繊維の捲縮は、他素材の繊維と比較して伸びやすい傾向にあることから、良好な外観と風合いを有するパイル布帛が得られる。 The pile fiber includes acrylic fiber and / or acrylic fiber. Thereby, the pile fabric excellent in the texture is obtained. In general, when a thermoplastic fiber is used as a pile fiber and polishing is performed at a temperature equal to or higher than the melting point or softening point of the thermoplastic fiber, the pile fiber on the surface of the pile fabric is burnt or melted. A pile fabric having a good appearance and texture cannot be obtained. In addition, when polishing is performed at a temperature lower than the glass transition point of the thermoplastic fiber, the pile fabric on the surface of the pile fabric does not stretch, and thus a pile fabric having a good appearance and texture cannot be obtained. On the other hand, the crimp of acrylic fiber and acrylic fiber extends even at a temperature below the melting point. And since the glass transition point of acrylic fiber and acrylic fiber is about 100 ° C., and the softening point is about 150 to 230 ° C., when acrylic fiber and / or acrylic fiber is used as the pile fiber, Polishing can be performed at a temperature below the softening point, for example, 100 to 150 ° C. Furthermore, since the crimps of acrylic fibers and acrylic fibers tend to stretch more easily than fibers of other materials, a pile fabric having a good appearance and texture can be obtained.
　また、上記パイル繊維は、本発明の効果を阻害しない範囲内において、ポリエチレンテレフタレート、ポリトリメチレンテレタレート等のポリエステル樹脂を含む樹脂組成物を紡糸してなる合成繊維やその他の繊維を含んでもよい。 In addition, the pile fiber may include a synthetic fiber or other fiber formed by spinning a resin composition containing a polyester resin such as polyethylene terephthalate or polytrimethylene terephthalate within a range that does not impair the effects of the present invention. .
　上記パイル繊維は、地糸を構成する繊維よりも軟化点が低ければ良く特に限定されないが、地糸を構成する繊維と上記パイル繊維の軟化点の差は、好ましくは１０℃以上であり、より好ましくは２０℃以上、特に好ましくは３０℃以上である。１０℃以上の差があると、パイル布帛の裏面において地糸より外側に配置された一部又は全部のパイル繊維のみを熱圧着することで融着させ、上記地組織の表面に立毛するパイル繊維を熱圧着させない（融着させない）ことがより容易となる。 The pile fiber is not particularly limited as long as the softening point is lower than the fiber constituting the ground yarn, but the difference between the softening point of the fiber constituting the ground yarn and the pile fiber is preferably 10 ° C or more, and more Preferably it is 20 degreeC or more, Most preferably, it is 30 degreeC or more. If there is a difference of 10 ° C. or more, only a part or all of the pile fibers arranged outside the ground yarn on the back surface of the pile fabric are fused by thermocompression bonding, and the pile fiber is raised on the surface of the ground structure It is easier not to thermocompression-bond (not fuse).
　上記パイル繊維は全量所定の温度で軟化する繊維であっても良く、異なる温度で軟化する繊維の混合繊維であっても良い。そして、パイル繊維が異なる温度で軟化する繊維の混合繊維である場合は、相対的に低い温度で軟化する繊維を２０重量％以上混合し、相対的に低い温度で軟化する繊維を熱圧着させることが好ましく、より好ましくは相対的に低い温度で軟化する繊維が５０重量％以上混合されている。 The whole pile fiber may be a fiber softened at a predetermined temperature, or may be a mixed fiber of fibers softened at different temperatures. And when the pile fiber is a mixed fiber of fibers that soften at different temperatures, 20% by weight or more of fibers that soften at a relatively low temperature are mixed, and the fibers that soften at a relatively low temperature are thermocompression bonded. More preferably, 50% by weight or more of fibers that soften at a relatively low temperature are mixed.

The adhesion amount of the organically modified silicone softener is preferably 0.4 to 2.5 parts by weight, more preferably 0.4 to 2.0 parts by weight with respect to parts by weight. More preferably, it is 4 to 1.5 parts by weight. When the adhesion amount of the organic-modified silicone softener is within the above range, the pile fiber can be prevented from coming loose while effectively increasing the flexibility of the pile fabric. The adhesion amount of organically modified silicone softeners such as amino-modified silicone softeners on pile fibers can be determined, for example, by fluorescent X-ray analysis. For example, the adhesion amount of the amino-modified silicone softener can be calculated from a calibration curve by quantifying Si element by a fluorescent X-ray analysis method using a wavelength dispersive X-ray fluorescence analyzer. Specifically, using an X-ray fluorescence analyzer RIX3100 (manufactured by Rigaku Corporation), Rh tube (tube current 50 mA-tube voltage 50 kV), measurement diameter 30 mmφ, spectral crystal pentaerythritol (PET), 2θ angle 106 The Si element is analyzed under a condition of ˜112 °, and a calibration curve is first created using a sample whose content of the amino-modified silicone softener is known. Next, Si element was measured in a measurement sample (thickness 3 mm, diameter 30 mm) obtained by pressure-forming a measurement target fiber such as a portion (pile fiber) other than the ground yarn on the back of the pile fabric with a press (tablet molding machine). Perform an analysis. By substituting the obtained Si detection count into the calibration curve equation, the adhesion amount of the amino-modified silicone softener can be calculated.

　以下、図面を用いて本発明のパイル布帛を説明する。図１は本発明のパイル布帛の一実施形態のハイパイル布帛における地糸と地糸に絡むパイル繊維の位置関係を説明する模式図である。図１に示すように、ハイパイル布帛５は、メリヤスのループ６を構成する地糸１と、地糸１のループ６に絡み地組織（ハイパイル布帛５）の表面７に開繊され立毛パイル３を形成しているパイル繊維２で構成される。また、地組織（ハイパイル布帛５）の裏面８において、地糸１の外側に配置されているパイル繊維２の少なくとも一部は熱圧着されて熱圧着部４を構成し、地糸１に熱圧着されている。パイル布帛の裏面に付着している有機変性シリコーン系柔軟剤は省略している。なお、図１は、概ね、地糸１の下側にパイル繊維２を重ねるような位置関係を模式的に示しているが、本図において地糸１の外側とは、概ね地糸１の下側の部分を意味する。 Hereinafter, the pile fabric of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram for explaining the positional relationship between a ground yarn and pile fibers entangled with the ground yarn in a high pile fabric according to an embodiment of the pile fabric of the present invention. As shown in FIG. 1, the high pile fabric 5 is spread on the surface 7 of the ground fabric (high pile fabric 5) entangled with the ground yarn 1 constituting the knitted loop 6 and the loop 6 of the ground yarn 1. The pile fiber 2 is formed. In addition, on the back surface 8 of the ground structure (high pile fabric 5), at least a part of the pile fibers 2 arranged outside the ground yarn 1 is thermocompression bonded to form the thermocompression bonding portion 4, and the thermocompression bonding to the ground yarn 1 is performed. Has been. The organically modified silicone softener adhering to the back surface of the pile fabric is omitted. Note that FIG. 1 schematically shows a positional relationship in which pile fibers 2 are generally stacked on the lower side of the ground yarn 1, but in this figure, the outside of the ground yarn 1 is generally below the ground yarn 1. Means the side part.
　以下、本発明のパイル布帛の製造方法を説明する。 Hereinafter, the manufacturing method of the pile fabric of this invention is demonstrated.
　まず、アクリル繊維及びアクリル系繊維からなる群から選ばれる少なくとも一つの繊維を含むパイル繊維と、上記パイル繊維より軟化点が高い地糸を用い、常法により、地組織と、上記地組織を構成する地糸に絡みかつ上記地組織の表面に立毛するパイル繊維を含むパイル布帛を作製する。パイル繊維は、好ましくはアクリル繊維及び／又はアクリル系繊維で構成される。この工程において、上記パイル繊維として、有機変性シリコーン系柔軟剤を付着したパイル繊維を用いた場合は、後述するパイル布帛の裏面に上記アミノ変性シリコーン系柔軟剤などの有機変性シリコーン系柔軟剤を付着させる工程を省略することもできるし、更に有機変性シリコーン系柔軟剤を塗布しても良い。パイル繊維へのアミノ変性シリコーン系柔軟剤などの有機変性シリコーン系柔軟剤の付着方法は、特に限定されず、公知の方法を適宜採用すればよい。例えば、パイル繊維を有機変性シリコーン系柔軟剤に浸漬してもよく、パイル繊維に有機変性シリコーン系柔軟剤を噴霧塗布してもよい。工程の簡便性から、パイル繊維への有機変性シリコーン系柔軟剤の付着は、染色と同時に行うことができる。もちろん、染色とは別工程で行ってもよいが、染色と別工程で行う場合は、パイル布帛の柔軟性を向上させる観点から、染色工程後に有機変性シリコーン系柔軟剤を付着させることが好ましい。上記有機変性シリコーン系柔軟剤は、一種で用いてもよく、二種以上を組み合わせて用いてもよい。なお、パイル布帛の原料として市販の有機変性シリコーン系柔軟剤（アミノ変性シリコーン系柔軟剤など）が付着している繊維を用いてもよい。市販の有機変性シリコーン系柔軟剤が付着している繊維をパイル繊維として用いる場合、パイル布帛を製造する前に、さらに繊維に有機変性シリコーン系柔軟剤を付着させてもよい。 First, using a pile fiber containing at least one fiber selected from the group consisting of an acrylic fiber and an acrylic fiber, and a ground yarn having a softening point higher than that of the pile fiber, a ground structure and the ground structure are configured by a conventional method. A pile fabric including pile fibers that are entangled with the ground yarn to be raised and raised on the surface of the ground structure is produced. The pile fiber is preferably composed of acrylic fiber and / or acrylic fiber. In this step, when a pile fiber to which an organically modified silicone softener is attached is used as the pile fiber, an organically modified silicone softener such as the above amino modified silicone softener is attached to the back surface of the pile fabric described later. The process to make can also be abbreviate | omitted and you may apply | coat an organic modified silicone type softening agent further. The method for attaching an organically modified silicone softener such as an amino-modified silicone softener to the pile fiber is not particularly limited, and a known method may be appropriately employed. For example, the pile fiber may be dipped in an organically modified silicone softener, or the organically modified silicone softener may be sprayed onto the pile fiber. Due to the simplicity of the process, the adhesion of the organically modified silicone softener to the pile fiber can be performed simultaneously with the dyeing. Of course, it may be carried out in a separate process from dyeing, but when it is carried out in a separate process from dyeing, it is preferable to attach an organically modified silicone softener after the dyeing process from the viewpoint of improving the flexibility of the pile fabric. The said organic modified silicone type softening agent may be used by 1 type, and may be used in combination of 2 or more type. In addition, you may use the fiber to which the commercially available organic modified silicone softener (Amino modified silicone softener etc.) has adhered as a raw material of a pile fabric. When using a fiber to which a commercially available organically modified silicone softener is attached as a pile fiber, an organically modified silicone softener may be further attached to the fiber before producing the pile fabric.
　次に、パイル布帛の裏面に上記アミノ変性シリコーン系柔軟剤などの有機変性シリコーン系柔軟剤を付着させる。これにより、パイル布帛の裏面において、パイル繊維に有機変性シリコーン系柔軟剤が付着されることになる。パイル布帛の裏面へのアミノ変性シリコーン系柔軟剤などの有機変性シリコーン系柔軟剤の付着方法は、特に限定されず、公知の方法を適宜採用すればよい。例えば、パイル布帛の裏面に有機変性シリコーン系柔軟剤を含浸させてもよく、パイル布帛の裏面に有機変性シリコーン系柔軟剤を噴霧塗布してもよい。上記有機変性シリコーン系柔軟剤は、一種で用いてもよく、二種以上を組み合わせて用いてもよい。 Next, an organically modified silicone softener such as the amino-modified silicone softener is adhered to the back surface of the pile fabric. As a result, the organically modified silicone softener is attached to the pile fiber on the back surface of the pile fabric. The method for adhering an organically modified silicone softener such as an amino-modified silicone softener to the back surface of the pile fabric is not particularly limited, and a known method may be adopted as appropriate. For example, the back surface of the pile fabric may be impregnated with an organically modified silicone softener, or the back surface of the pile fabric may be spray-coated with the organically modified silicone softener. The said organic modified silicone type softening agent may be used by 1 type, and may be used in combination of 2 or more type.
　柔軟剤は、通常、繊維の表面に柔軟性や滑り性などを付与するが、本願では、驚くことに、アクリル繊維及びアクリル系繊維からなる群から選ばれる少なくとも一つの繊維をパイル繊維とし、パイル布帛の裏面においてパイル繊維の地糸より外側に配置されているパイル繊維のうち少なくとも一部のパイル繊維を融着させるパイル布帛において、上述した有機変性シリコーン系柔軟剤をパイル布帛の裏面におけるパイル繊維に、パイル繊維１００重量部に対して０．４重量部以上付着させることで、パイル布帛の柔軟性を向上しつつ、パイル繊維の毛抜けも抑制することができる。その理由は明確ではないが、パイル布帛の裏面におけるパイル繊維に有機変性シリコーン系柔軟剤を付着させ、後述するように、パイル布帛の裏面側を上記パイル繊維の軟化点以上かつ上記地組織を構成する繊維の軟化点未満の温度で熱圧着することで、パイル布帛の裏面においてパイル繊維に付着している有機変性シリコーン系柔軟剤における末端アミノ基等の官能基が架橋されるためであると推測される。パイル布帛の柔軟性を向上しつつ、パイル繊維の毛抜けをより効果的に抑制する観点から、有機変性シリコーン系柔軟剤が付着していないパイル繊維又は有機変性シリコーン系柔軟剤が付着されているパイル繊維を用いてパイル布帛を作製した後、パイル布帛の裏面側に有機変性シリコーン系柔軟剤を付着させることが好ましい。 The softener usually imparts flexibility and slipperiness to the surface of the fiber, but in the present application, surprisingly, at least one fiber selected from the group consisting of acrylic fiber and acrylic fiber is used as the pile fiber, In the pile fabric in which at least a part of the pile fibers arranged outside the pile fiber ground yarn is fused on the back surface of the fabric, the above-mentioned organically modified silicone softener is piled on the back surface of the pile fabric. Further, by attaching 0.4 part by weight or more to 100 parts by weight of the pile fiber, the pile fiber can be prevented from being loosened while improving the flexibility of the pile fabric. The reason for this is not clear, but an organically modified silicone softener is attached to the pile fiber on the back side of the pile fabric, and the back side of the pile fabric constitutes the above-mentioned ground texture above the softening point of the pile fiber, as will be described later. Presumed to be because functional groups such as terminal amino groups in the organically modified silicone softener adhering to the pile fiber on the back surface of the pile fabric are cross-linked by thermocompression bonding at a temperature lower than the softening point of the fiber. Is done. From the viewpoint of more effectively suppressing pile fiber hair removal while improving the flexibility of the pile fabric, the pile fiber or the organically modified silicone softener to which the organically modified silicone softener is not attached is attached. After producing a pile fabric using a pile fiber, it is preferable to adhere an organically modified silicone softener to the back side of the pile fabric.
　次に、上記パイル布帛の裏面側を上記パイル繊維の軟化点以上かつ上記地組織を構成する繊維の軟化点未満の温度で熱圧着する。これにより、上記地組織の表面に立毛するパイル繊維は融着させず、上記地組織の裏面において上記地組織を構成する地糸より外側に配置されているパイル繊維の一部又は全部を融着させる。熱圧着処理は、例えば、パイル布帛を裏面が加熱ロール又はホットプレートに接触するように配置し、ゴムロールなどにより加圧することにより行うことができる。加熱ロール又はホットプレートを用いる場合、短時間の熱圧着処理を行うことができ、地組織の裏面において、地糸より外側に配置されているパイル繊維の少なくとも一部を熱圧着することができる。そして、パイル布帛の表面のパイル繊維が溶融するほどの加熱はしないため、地組織の表面に立毛するパイル繊維は溶融しない。 Next, the back side of the pile fabric is thermocompression bonded at a temperature not lower than the softening point of the pile fiber and lower than the softening point of the fiber constituting the ground structure. As a result, pile fibers raised on the surface of the ground structure are not fused, and a part or all of the pile fibers arranged outside the ground yarn constituting the ground structure is fused on the back surface of the ground structure. Let The thermocompression treatment can be performed, for example, by placing a pile fabric so that the back surface is in contact with a heating roll or a hot plate, and pressurizing with a rubber roll or the like. When a heating roll or a hot plate is used, a short-time thermocompression treatment can be performed, and at least a part of the pile fibers arranged outside the ground yarn can be thermocompression bonded on the back surface of the ground structure. And since the heating which does not melt the pile fiber on the surface of the pile fabric is not performed, the pile fiber raised on the surface of the ground texture is not melted.
　上記パイル布帛の裏面側から熱圧着処理する際及び／又は熱圧着処理した後、パイル布帛の表面に立毛するパイル繊維側は冷却することが好ましい。また、上記パイル布帛の裏面側から熱圧着処理した後、上記パイル布帛の裏面側を冷却することが好ましい。上記冷却手段として、パイル布帛の表面及び/又は裏面を水温５０℃以下の水を通水させた冷却ロールで冷却することが好ましい。上記冷却ロールに通水させる水の水温は、冷却効率及び生産性の観点から、好ましくは１０～４０℃であり、より好ましくは１０～３５℃であり、さらに好ましくは１５～３０℃である。このような冷却を行うと、パイル布帛の寸法安定性が保持でき、かつパイル繊維への熱ダメージも軽減させることができる。 When the thermocompression treatment is performed from the back side of the pile fabric and / or after the thermocompression treatment, the pile fiber side raised on the surface of the pile fabric is preferably cooled. Moreover, it is preferable to cool the back surface side of the pile fabric after performing the thermocompression treatment from the back surface side of the pile fabric. As the cooling means, it is preferable to cool the surface and / or back surface of the pile fabric with a cooling roll in which water having a water temperature of 50 ° C. or less is passed. The water temperature of water passed through the cooling roll is preferably 10 to 40 ° C., more preferably 10 to 35 ° C., and further preferably 15 to 30 ° C. from the viewpoint of cooling efficiency and productivity. When such cooling is performed, the dimensional stability of the pile fabric can be maintained, and thermal damage to the pile fiber can be reduced.
　本発明のパイル布帛の製造方法の一例における熱圧着処理を、図を用いてさらに詳細に説明する。 The thermocompression treatment in an example of the method for producing a pile fabric of the present invention will be described in more detail with reference to the drawings.
　図２は、パイル布帛を裏面側から所定温度で熱圧着処理する工程を模式的に示した製造工程図である。熱圧着処理、具体的には熱圧着処理に使用する加工装置１０は、ポリテトラフルオロエチレン等のフッ素樹脂をコーティングした加熱ロール１１と、加熱ロール１１に加圧し、内部に３０℃の冷却水が通水する冷却ゴムロール１２と、冷却ゴムロール１２に加圧し、内部に３０℃の冷却水が通水する金属冷却ロール１３、内部に３０℃の冷却水が通水する金属冷却ロール１４と、ガイドロール１５を含む。パイル布帛原反（有機変性シリコーン系柔軟剤を付着させたハイパイル布帛）１８は容器１６から導き出され、裏面１８ｂが加熱ロール１１に接触し、表面（立毛パイル側）１８ａが冷却ゴムロール１２に接触するように供給する。また、熱圧着処理された後、裏面１８ｂは、金属冷却ロール１４で冷却される。加工の終了したパイル布帛１９は、容器１７に収納される。なお、熱圧着処理は、図２に示した加工装置に限定されず、図２に示した加工装置の一部の構成を変更した装置、ホットプレート、及びその他の装置を用いて行っても良い。例えば、冷却ゴムロール１２の代わりに冷却しないゴムロールを用いることが可能であり、金属冷却ロール１３は省略しても良い。熱圧着処理において、加熱温度はパイル繊維の軟化点以上かつ地糸を構成する繊維の軟化点未満であれば良く、加圧力は線圧で０．０１～１００Ｋｇｆ／ｃｍ２（０．９８ＫＰａ～９．８ＭＰａ）、原反の供給速度は０．１～２０ｍ／分、ヒーター（加熱ロールなど）接触時間は１～６０秒間であることが好ましい。また、パイル布帛の表面のダメージを軽減するという観点から、加圧力は線圧で２．０～５０Ｋｇｆ／ｃｍ２（０．２０～４．９ＭＰａ）、ヒーター接触時間は１～１０秒間であることがより好ましい。 FIG. 2 is a manufacturing process diagram schematically showing a process of thermocompression-bonding the pile fabric from the back side at a predetermined temperature. The processing apparatus 10 used for the thermocompression treatment, specifically, the thermocompression treatment, pressurizes the heating roll 11 coated with a fluororesin such as polytetrafluoroethylene, and the heating roll 11, and contains 30 ° C. cooling water inside. Cooling rubber roll 12 that passes water, metal cooling roll 13 that pressurizes cooling rubber roll 12 and allows 30 ° C. cooling water to flow inside, metal cooling roll 14 that allows 30 ° C. cooling water to flow inside, and guide roll 15 is included. The pile fabric original fabric (high pile fabric to which an organically modified silicone softener is attached) 18 is led out of the container 16, the back surface 18 b comes into contact with the heating roll 11, and the front surface (napped pile side) 18 a comes into contact with the cooling rubber roll 12. To supply. Further, after the thermocompression treatment, the back surface 18 b is cooled by the metal cooling roll 14. The pile fabric 19 that has been processed is stored in the container 17. The thermocompression treatment is not limited to the processing apparatus shown in FIG. 2, and may be performed using an apparatus, a hot plate, and other apparatuses in which a part of the processing apparatus shown in FIG. 2 is changed. . For example, instead of the cooling rubber roll 12, a rubber roll that is not cooled can be used, and the metal cooling roll 13 may be omitted. In the thermocompression treatment, the heating temperature may be not less than the softening point of the pile fiber and less than the softening point of the fiber constituting the ground yarn, and the applied pressure may be 0.01-100 kgf / cm 2 (0.98 KPa-9) in terms of linear pressure. 0.8 MPa), the feed rate of the original fabric is preferably 0.1 to 20 m / min, and the contact time of the heater (heating roll or the like) is preferably 1 to 60 seconds. Also, from the viewpoint of reducing damage to the surface of the pile fabric, the applied pressure is a linear pressure of 2.0 to 50 kgf / cm 2 (0.20 to 4.9 MPa), and the heater contact time is 1 to 10 seconds. Is more preferable.
　ハイパイル布帛の場合、熱圧着処理の際、ハイパイル布帛がウェール方向に収縮することから、熱圧着処理後、ウェール方向に延伸処理しても良い。 In the case of a high pile fabric, since the high pile fabric contracts in the wale direction during the thermocompression treatment, it may be stretched in the wale direction after the thermocompression treatment.
　延伸処理としては、ハイパイル布帛のウェール方向の両側端部（布耳部）を把持して、ウェール方向長さの延伸率が５～２０％程度になるようにウェール方向に引張ることが好ましく、より好ましくは７～１５％程度、さらに好ましくは８～１２％程度である。ウェール方向長さの延伸率は、下記式で示されるものである。
ウェール方向長さの延伸率（％）＝{（延伸後のウェール方向長さ－延伸前のウェール方向長さ）／延伸前のウェール方向長さ}×１００ As the stretching treatment, it is preferable to grip both ends (cloth ears) of the high pile fabric in the wale direction and pull in the wale direction so that the stretch ratio of the length in the wale direction is about 5 to 20%. Preferably it is about 7 to 15%, more preferably about 8 to 12%. The stretch ratio of the length in the wale direction is represented by the following formula.
Stretch ratio (%) of length in the wale direction = {(length in the wale direction after stretching−length in the wale direction before stretching) / length in the wale direction before stretching} × 100
　また、延伸処理の際に加熱する場合は、９０～１５０℃で延伸処理することが好ましく、１００～１３０℃がより好ましく、１０５～１２０℃がさらに好ましい。 Further, when heating is performed during the stretching treatment, the stretching treatment is preferably performed at 90 to 150 ° C., more preferably 100 to 130 ° C., and further preferably 105 to 120 ° C.
　このような延伸処理は、例えばテンター等の公知の装置を用いて行うことができる。テンターは、一般的には、所定の温度で加熱しながら、布帛の両布耳部を保持して布帛を所定の幅に拡幅して熱セットするのに用いられるが、本発明では、上記のように、加熱しても加熱しなくても良い。また、テンターでは、布帛の布耳部を保持する方式としてクリップテンター方式とピンテンター方式があり、いずれを採用しても良いが、工程の安定性及び／又は生産性の観点から、ピンテンター方式を採用するのが好ましい。 Such a stretching treatment can be performed using a known device such as a tenter. The tenter is generally used to heat and set the fabric to a predetermined width while holding both the fabric ears while heating at a predetermined temperature. As such, it may be heated or not. In addition, in the tenter, there are a clip tenter method and a pin tenter method as a method for holding the cloth ear part of the fabric, either of which can be adopted, but from the viewpoint of process stability and / or productivity, the pin tenter method is adopted. It is preferable to do this.
　上記延伸処理を、ハイパイル布帛を加熱しながら行う場合は、ハイパイル布帛の表面にダメージを与えないよう、必要最小限の温度、必要最小限の風量で行うことが好ましい。 When the above stretching treatment is performed while heating the high pile fabric, it is preferably performed at the minimum necessary temperature and the minimum necessary air volume so as not to damage the surface of the high pile fabric.

More preferably, it is more preferably 2.0 g / m 2 or less. Further, the maximum amount of hair loss measured by the method described later is preferably 5.0 g / m 2 or less, more preferably 4.0 g / m 2 or less, and 3.0 g / m 2 or less. Is more preferable.
