The specific embodiment
The present invention relates to a kind of pile fabric, it comprises with respect to the fiber that constitutes whole fine hair part and is the acrylic fibers (A) of 40～80 weight % and is the acrylic fibers (B) of 20～60 weight % with respect to the fiber that constitutes above-mentioned whole fine hair part, and average fluff length is 12～30mm; Wherein, the fibre section of described acrylic fibers (A) is the pancake of aspect ratio in 9～15 scope, and fiber number is 6～10dtex, and has the concavo-convex of 0.25～1.5 μ m on the direction vertical with the fiber axis of fiber surface; Described acrylic fibers (B) has the fibre section of aspect ratio in 1～4 scope, and fiber number is 2～8dtex.
Wherein so-called aspect ratio is meant the length of major axis of fibre section and the length ratio of minor axis, more particularly, is to represent divided by the value of the length gained of minor axis by the length of major axis.In addition, so-called pancake is meant, from oval, intersect circle, cocoon shape, circle, dog bone shape and be with the cross sectional shape of selecting among the shape.
When the aspect ratio of described acrylic fibers (A) less than 9 the time, although also the fiber number with the fiber of using with is relevant, but when the fiber number of the fiber of using with is thin, cause convergence, the pile handleability of pile fabric has the tendency of deterioration, if and aspect ratio surpasses 15, then because the fiber number of this acrylic fibers (A) is less, so pile fabric exists and lacks restorative tendency.
Restorative being meant of so-called shortage applies load from vertical direction directly over pile fabric, even take this load afterwards away, the fiber that constitutes fine hair also is difficult to from compressed recovering state to initial state.
In addition,,, therefore lack sense of fullness, resilience variation because the aspect ratio of acrylic fibers (A) is higher when fiber number during less than 6dtex, and if surpass 10dtex, then have the hard slightly tendency of feel that becomes, so not preferred.
In addition, concavo-convex during when what form less than 0.25 μ m in the direction vertical with the fiber axis of the fiber surface of described acrylic fibers (A), even adopt of the present invention fibrous, also can in pile fabric, produce adhesion etc., be difficult to bring into play good pile handleability, do not have tangible difference with existing product.On the other hand, when surpassing 1.5 μ m, feel young pilose antler injustice (roughness), and fiber itself ruptures easily, and processabilities such as weaving property have the tendency of variation.
When the composition of such acrylic fiber (A) with respect to the fiber that constitutes whole fine hair part during less than 40 weight %, in pile fabric, can not bring into play the feature of the described acrylic fibers (A) of having stipulated fibre section shape, fiber number, concave-convex surface, and as broad as long and do not have a good pile handleability with existing product; And when surpassing 80 weight %, wool top intensity variation, the processability of combing etc. reduce, and formed pile fabric also lacks sense of fullness and resilience.
Preferred embodiment be, with be 40～80 weight % with respect to the fiber that constitutes whole fine hair part, more preferably the ratio of 50～75 weight % contains described acrylic fibers (A), and being that the ratio of 20～60 weight %, preferred 20～50 weight % contains acrylic fibers (B) with respect to the fiber that constitutes whole fine hair part, wherein to have aspect ratio be 1～4 to this acrylic fibers (B), be preferably the fibre section in 1.5～3.5 scopes, and fiber number is 2～8dtex, 3～5.7dtex more preferably.
If the ratio of described acrylic fibers (A) is with respect to constituting whole fine hair fiber partly less than 40 weight %, then because above-mentioned reason, do not have difference and do not have good pile handleability with existing product, and when surpassing 80 weight %, when contacting with pile fabric, mix and used the effect of this acrylic fibers (B) little, lack sense of fullness and restorative.
In addition, if the aspect ratio of the fibre section of described acrylic fibers (B) surpasses 4, then when mixing use with this acrylic fibers (A), the aspect ratio that constitutes all fibers of fine hair part becomes big, the shortage sense of fullness, and resilience also dies down.
When fiber number during, because the aspect ratio of this acrylic fibers (A) of mixing is big, therefore also still lack sense of fullness, resilience also dies down less than 2dtex.On the other hand, when fiber number surpasses 8dtex,,, have the tendency that produces hard feel by mix use with them although it is big to mix the aspect ratio of the described acrylic fibers of using (A).
When the mixed proportion of described acrylic fibers (B) with respect to the fiber that constitutes whole fine hair part during less than 20 weight %, when contacting with pile fabric, mix and use the effect of acrylic fibers (B) little, lack sense of fullness and restorative, if and surpass 60 weight %, the effect of then mixing acrylic fibers (A) is little, then has the convergence tendency, can not show good pile handleability.
Preferred embodiment is, comprise with respect to the fiber that constitutes whole fine hair part and be 5～25 weight %, be preferably the formed pile fabric of acrylic fibers (C) of 10～20 weight %, it is 3～15 that wherein said acrylic fibers (C) has aspect ratio, be preferably 6～13 fibre section, and fiber number is 12～33dtex, be preferably 15～25dtex.
Mix and use the purpose and the effect of this acrylic fibers (C) to be, in order to demonstrate the thorn feel of wool that atural fur has, under the situation of considering these, when aspect ratio less than 3 the time, because the fiber number of described acrylic fibers (C) is thick, so produced the above hard feel of degree of the thorn feel of wool, on the other hand, when aspect ratio surpasses 15,, therefore feel the visual foreign body sensation that the fibre section is highlighted because the fiber number of this acrylic fibers (C) is bigger.The thorn feel of wool described here is meant also sentient piloerection sense in the soft feel that can experience when contacting with atural fur.
In addition, when fiber number during, be difficult to show the thorn feel of wool, and when fiber number surpassed 33dtex, then the filament fiber number was thick, produces hard feel etc. as desired effect less than 12dtex.
At this moment, when with respect to the ratio of this acrylic fibers (C) of the fiber that constitutes whole fine hair part during less than 5 weight %, the effect of mixing described acrylic fibers (C) is insufficient, otherwise, when surpassing 25 weight %, because the fiber number of this acrylic fibers is big, the above foreign matter that has of degree that then can produce the thorn feel of wool is sneaked into such feel that scrapes, so not preferred.
