The hair material for the brush is an island in one or both ends of a sea-island composite fiber containing two or more types of resins with different drug dissolution speeds. The exposed brush hair material is characterized in that the outer peripheral surface forming part of the sea-island composite fiber is composed of only the sea part, and the island part of the sea-island composite fiber is in the cross section of the sea-island composite fiber, and it is present on the outer periphery. The central part other than the surface forming part. The present invention can provide brush bristles and brushes that do not damage objects to be cleaned, have excellent cleaning properties, and have excellent durability.
Description
本發明係關於適合包含牙刷的各種刷子之刷子用毛材及使用其之刷子。 The present invention relates to brush bristles suitable for various brushes including toothbrushes and brushes using the same.
以往，使用合成纖維的單絲作為刷子用毛材之技術已廣為人知。於使用此種刷子用毛材之刷子，例如牙刷，希望由毛尖所帶來的牙齒之清掃效果與儘可能不損傷被清掃物的柔軟觸感或牙齦等的按摩效果係平衡良好且優異。 In the past, the technology of using monofilaments of synthetic fibers as brush hair materials has been widely known. For brushes using such brush bristles, such as toothbrushes, it is desirable that the cleaning effect of the teeth brought by the hair tips and the soft touch of the object to be cleaned or the massage effect of the gums and the like are well balanced and excellent.
然而，刷子用毛材到毛尖為止皆以單一材質的單絲所形成者，係難以滿足如此的要求。即，到毛尖為止皆以單一材質的單絲所形成者，若將刷子用毛材加粗，則刷子的韌性亦變強，雖然對於牙齒的平坦面之清掃效果或牙齦等的按摩效果提高，但反而有齒間的清掃效果降低、或對牙齦等的觸感變得過強而容易損傷牙齦等之虞。 However, it is difficult to satisfy such a requirement that the brush hair material is formed of monofilaments of a single material up to the tip. That is, if the hair tip is made of monofilaments of a single material, if the brush hair material is thickened, the toughness of the brush will also increase, although the cleaning effect on the flat surface of the teeth and the massage effect on the gums are improved. However, on the contrary, there is a possibility that the cleaning effect between teeth is reduced, or the touch to the gums becomes too strong, and the gums are easily damaged.
又，於到毛尖為止皆以單一材質的單絲所形成者，雖然若使刷子用毛材變細，則齒間的清掃效果提高，但刷子用毛材的韌性係在全長之各處變弱，有牙齦等的按摩效果降低、或毛材本身的耐久性降低之虞。 In addition, if the brush hair material is made of monofilaments of a single material up to the tip of the hair, the cleaning effect between the teeth is improved if the brush hair material is made thinner, but the toughness of the brush hair material is weakened throughout the entire length , There is a possibility that the massage effect of the gums will be reduced, or the durability of the wool material itself may be reduced.
於其它領域的清掃用或洗淨用的刷子，亦有大致同樣的問題。 Brushes used for cleaning or washing in other fields have roughly the same problem.
因此，為了使優異的清掃效果與難以損傷被清掃物的特性平衡良好地並存，有提案一種刷子用毛材，其係使用海島複合纖維作為刷子用毛材，於用於刷子時的毛材之根部係作成海島成分成為一體之複合纖維構造，於前端部係作成使多數的島部外露、分纖之構造(專利文獻1)。藉由使用此刷子用毛材，可使優異的清掃效果與難以損傷被清掃物的特徵平衡良好地並存，而且藉由外露的前端部之細的島部纖維，可得到柔軟的觸感。 Therefore, in order to balance the excellent cleaning effect and the characteristics of being difficult to damage the object to be cleaned, a brush hair material has been proposed, which uses sea-island composite fiber as the brush hair material, which is one of the hair materials used in the brush. The root is a composite fiber structure in which the sea-island components are integrated, and the tip is a structure in which most islands are exposed and split (Patent Document 1). By using this brush hair material, the excellent cleaning effect and the feature of hardly damaging the object to be cleaned can be coexisted in a good balance, and the thin island fibers at the exposed tip can provide a soft touch.
然而，於上述專利文獻1所提案的刷子用毛材中，留下如以下之問題。即，由於係島部遍布於作為刷子用毛材使用的海島複合纖維的橫剖面之全部區域而分布、且該島部在毛材的前端部外露之構造，而於實際使用於牙刷等的情況中，當因摩擦等的外力施加於外露的島部時，取決於外力的大小，有在毛材根部支撐該外露的島部之海部裂開的可能性，留下有耐久性變得不充分之虞的問題。 However, the brush hair material proposed in Patent Document 1 has the following problems. That is, because the islands are distributed throughout the entire cross-sectional area of the sea-island composite fiber used as a brush hair material, and the islands are exposed at the tip of the hair material, it is actually used in toothbrushes, etc. However, when an external force such as friction is applied to the exposed island, depending on the magnitude of the external force, there is a possibility that the sea part supporting the exposed island at the root of the wool may crack, and the remaining durability will become insufficient The question of concern.
附帶一提，除了如上述關於以往的刷子用毛材之問題，最近有提案一種海島複合纖維之製造技術，其可將島部之分布狀態或島部之橫剖面形狀形成各種的形態(專利文獻2~4)。高度期待若依據此提案技術，則在海島複合纖維中，可將相對於海部之島部的大小或配置、剖面形狀、配置密度等予以實質上自由地設計，可應付各種領域中的各種要求。
Incidentally, in addition to the above-mentioned problems with the conventional brush bristles, there has recently been proposed a technology for the production of sea-island composite fibers, which can form the distribution state of the islands or the cross-sectional shape of the islands into various shapes (

因此，本發明之課題係著眼於如以往之專利文獻1中記載的刷子用毛材之優異特徵與留下的問題點，同時著眼於最近提案之主要能實質上自由地設計島部的海島複合纖維之製造技術，提供不損傷被清掃物、兼具優異的清掃性、而且具有優異的耐久性之刷子用毛材與使用其之刷子。 Therefore, the subject of the present invention is to focus on the excellent characteristics and remaining problems of brush hair materials as described in the previous patent document 1, and also focus on the recent proposal of the island compound that allows the island to be designed substantially freely. The fiber manufacturing technology provides brush bristles and brushes that do not damage the object to be cleaned, have excellent cleaning performance, and have excellent durability.
為了解決上述課題，本發明之刷子用毛材係包含下述者，其係使包含藥劑溶解速度不同的2種類以上之樹脂的海島複合纖維之長邊方向一端部或兩端部中的島部外露之刷子用毛材，其特徵為：形成前述海島複合纖維的外周面之外周面形成部係僅以海部構成，該海島複合纖維的島部係在該海島複合纖維的橫剖面中，偏向存在於前述外周面形成部以外之靠中央部的部位。 In order to solve the above-mentioned problems, the brush hair material of the present invention includes the islands at one or both ends of the sea-island composite fiber containing two or more types of resins with different drug dissolution rates The exposed brush hair material is characterized in that the outer peripheral surface forming part forming the sea-island composite fiber is composed of only the sea part, and the island part of the sea-island composite fiber is in the cross section of the sea-island composite fiber and is present in a biased manner. The part near the central part other than the outer peripheral surface forming part.
於此種本發明之刷子用毛材中，藉由成為使海島複合纖維之長邊方向一端部或兩端部(如後述，當 將刷子用毛材使用於刷子時，有毛材的一端部成為毛尖之情況與兩端部成為毛尖之情況這兩者)中的島部外露之刷子用毛材構造，由於成為「直接接觸被清掃物者實質上僅為在毛材前端部外露的複合纖維之細的島部，且該島部係在根部被複合纖維的海部所支撐」之形態，毛尖係以韌性相對弱的多數之外露島部所構成，例如即使對於齒間等之難以清掃的細小部位，亦表現優異的清掃性，且由於接觸被清掃物者係韌性弱的外露島部，而難以損傷被清掃物，可得到柔軟的觸感。又，由於直接接觸被清掃物者僅為複數的(多數的)細的島部，對於被清掃部位，不僅可發揮刮出污垢的機能，亦能發揮補集的機能，可表現更優異的清掃性。而且，形成海島複合纖維的外周面之外周面形成部係僅以海部構成，且海島複合纖維的島部係在該海島複合纖維的橫剖面中，偏向存在於外周面形成部以外之靠中央部的部位，藉此而緊鄰外周面形成部的島部變成在上述外露島部的根部及其附近部位(複合纖維側的部位)被某厚度以上的形成外周面形成部之海部所覆蓋，於對外露島部施加外力時，防止因該外力所造成的支撐外露島部之海部裂開，大幅提升刷子用毛材的耐久性。換言之，由於成為「海島複合纖維的島部係在該海島複合纖維的橫剖面中，變成偏向存在於以某厚度以上的海部所形成外周面形成部以外之靠中央部的部位，且該偏向存在的島部係在毛材前端部外露」之形態，故可活用由外露島部所帶來的難以損傷被清掃物、可得到優異的清 掃效果之優點，同時實現由包含某厚度以上的海部之外周面形成部所帶來的優異耐久性。 In the brush hair material of the present invention, the sea-island composite fiber has one or both ends in the longitudinal direction (as described later, when When the brush hair material is used for the brush, the brush hair material structure with the island part exposed in both the case where one end of the hair material becomes the tip of the hair and the case where the both ends becomes the tip of the hair The sweeper is essentially only the thin island of the composite fiber exposed at the tip of the wool, and the island is in the form of the root supported by the sea of the composite fiber", and the hair tips are exposed in the majority with relatively weak toughness. The island is composed of, for example, it has excellent cleaning performance even for small parts such as the teeth, etc., which are difficult to clean, and because the exposed island of the object is weak, it is difficult to damage the object to be cleaned, and softness can be obtained. The touch. In addition, since there are only plural (most) thin islands in direct contact with the object to be cleaned, the cleaned area not only has the function of scraping off dirt, but also has the function of complementing, which can perform more excellent cleaning. Sex. Moreover, the outer peripheral surface forming part of the outer peripheral surface forming the sea-island composite fiber is composed of only the sea part, and the island part of the sea-island composite fiber is formed in the cross section of the sea-island composite fiber, and is biased toward the central part other than the outer peripheral surface forming part. As a result, the island part next to the outer peripheral surface forming part becomes the root of the exposed island part and its vicinity (the part on the composite fiber side) covered by the sea part forming the outer peripheral surface forming part with a certain thickness or more. When an external force is applied to the exposed island part, the sea part supporting the exposed island part caused by the external force is prevented from cracking, and the durability of the brush bristles is greatly improved. In other words, since the island part of the "sea-island composite fiber" is in the cross section of the sea-island composite fiber, it tends to exist in the central part other than the outer peripheral surface formed by the sea part of a certain thickness or more, and the deviation exists The island part is exposed at the tip of the wool material", so it can make use of the hard-to-damage objects to be cleaned by the exposed island part, and excellent cleaning can be obtained. The advantages of the sweeping effect, while realizing the excellent durability brought by the outer peripheral surface forming part including the sea part above a certain thickness.
於上述本發明之刷子用毛材中，為了更確實地表現由上述外周面形成部所帶來的優異耐久性，構成外周面形成部的海部之厚度較佳為對於表現該優異耐久性為充分的值以上。為了達成此，上述海島複合纖維的橫剖面中之緊鄰上述外周面形成部的島部之直徑Di與上述外周面形成部的海部之厚度Ts之比率Ts/Di較佳為1.2以上。藉此，更確實地實現由包含指定厚度以上的海部之外周面形成部所帶來的優異耐久性。Ts/Di較佳為1.5以上，更佳為2.0以上。 In the brush hair material of the present invention, in order to more reliably express the excellent durability brought about by the outer peripheral surface forming portion, the thickness of the sea portion constituting the outer peripheral surface forming portion is preferably sufficient for expressing the excellent durability Above the value. In order to achieve this, the ratio Ts/Di of the diameter Di of the island portion adjacent to the outer peripheral surface forming portion to the thickness Ts of the sea portion of the outer peripheral surface forming portion in the cross section of the sea-island composite fiber is preferably 1.2 or more. Thereby, the excellent durability provided by the outer peripheral surface forming portion including the sea portion having a specified thickness or more can be realized more reliably. Ts/Di is preferably 1.5 or more, more preferably 2.0 or more.
又，於上述本發明之刷子用毛材中，作為在上述海島複合纖維之長邊方向一端部或兩端部外露的島部之外露長度，較佳在0.5~10mm之範圍，更佳為1~5mm之範圍。島部的外露長度若比0.5mm更短，則難以得到由外露島部所帶來的對於齒間等的細小部位之優異清掃性，又，亦難以得到良好的柔軟觸感。島部的外露長度若比10mm更長，則有韌性弱的外露島部變得過長之虞，產生外露島部過度變形而由外露島部所帶來的清掃效果(例如，補集污垢之效果)或牙齦等的按摩效果不足之虞。 In addition, in the brush hair material of the present invention, the length of the island exposed at one or both ends of the sea-island composite fiber in the longitudinal direction is preferably in the range of 0.5 to 10 mm, more preferably 1 ~5mm range. If the exposed length of the islands is shorter than 0.5 mm, it is difficult to obtain excellent cleaning properties for small parts such as interdental areas due to the exposed islands, and it is also difficult to obtain a good soft touch. If the exposed length of the island is longer than 10mm, the exposed island with weak toughness may become too long, resulting in excessive deformation of the exposed island and the cleaning effect brought by the exposed island (e.g. Effect) or the massage effect of gums, etc. may be insufficient.
又，於上述本發明之刷子用毛材中，上述島部之直徑、尤其是緊鄰外周面形成部的島部之直徑Di，較佳在1~20μm之範圍，更佳為1~10μm之範圍。此島部之直徑若小於1μm，則外露島部變得過細而外露島 部的韌性變得過弱，有變得難以得到在清掃所必須的外露島部之韌性之虞。島部之直徑若比20μm更大，則外露島部的韌性變得過強，有變得難以得到對於齒間等的細小部位之優異的清掃性，又，亦變得難以得到柔軟的觸感之虞。另外，於本發明中，所謂的島部之直徑，當島部之橫剖面形狀為圓形時係指其直徑，當為圓形以外的異形橫剖面形狀時係指外接圓的直徑。關於後述的海島複合纖維之直徑亦同樣。另外，關於此島部之直徑，也可全部的島部不是相同的粗細。 In addition, in the brush hair material of the present invention, the diameter of the island portion, especially the diameter Di of the island portion adjacent to the outer peripheral surface forming portion, is preferably in the range of 1-20 μm, more preferably in the range of 1-10 μm . If the diameter of this island is less than 1μm, the exposed island will become too thin and the exposed island The toughness of the part becomes too weak, and it may become difficult to obtain the toughness of the exposed island part necessary for cleaning. If the diameter of the island part is larger than 20μm, the toughness of the exposed island part becomes too strong, and it becomes difficult to obtain excellent cleaning performance for small parts such as teeth, and it becomes difficult to obtain a soft touch. The fear. In addition, in the present invention, the so-called diameter of the island part refers to the diameter of the circumscribed circle when the cross-sectional shape of the island part is a circle, and when it is a special cross-sectional shape other than a circle. The same applies to the diameter of the sea-island composite fiber described later. In addition, regarding the diameter of the island, all the islands may not have the same thickness.
又，作為上述海島複合纖維的橫剖面中的上述島部之數，較佳為20以上。因此，在1根形成刷子用毛材的海島複合纖維之長邊方向一端部或兩端部外露的島部之數亦較佳為20以上。藉由將此島部之數設為20以上，而變得容易藉由外露島部補集污垢，進一步提升清掃性，同時於要求保持化妝料等的性能或起泡性能等之情況中，亦變得容易發揮彼等性能。 Moreover, as the number of the said island part in the cross section of the said sea-island composite fiber, 20 or more is preferable. Therefore, the number of islands exposed at one end or both ends of the sea-island composite fiber forming the bristle material for the brush is also preferably 20 or more. By setting the number of islands to 20 or more, it becomes easier to replenish the dirt by the exposed islands, and further improve the cleaning performance. At the same time, it is also required to maintain the performance of cosmetics, etc. or foaming performance. It becomes easy to exert their performance.
又，於上述本發明之刷子用毛材中，上述海島複合纖維之直徑較佳在50~1,000μm之範圍，更佳為80~500μm之範圍。海島複合纖維之直徑若小於50μm，則使用於刷子時的海島複合纖維部本身的韌性變得過弱，取決於用途，有清掃效果降低之虞。海島複合纖維之直徑若超過1,000μm，則使用於刷子時的海島複合纖維部本身之韌性變得過強，雖然亦取決於前端部的外露島部之形態(長度或直徑)，但將外露島部的根部之海島複合纖維部強力推壓於被清掃物側，有變得容易損傷被清掃物之虞。 In addition, in the brush hair material of the present invention, the diameter of the sea-island composite fiber is preferably in the range of 50 to 1,000 μm, more preferably in the range of 80 to 500 μm. If the diameter of the sea-island composite fiber is less than 50 μm, the toughness of the sea-island composite fiber itself when used in a brush becomes too weak, and the cleaning effect may decrease depending on the application. If the diameter of the sea-island composite fiber exceeds 1,000μm, the toughness of the sea-island composite fiber itself when used in a brush becomes too strong. Although it depends on the shape (length or diameter) of the exposed island at the tip, the island will be exposed. The sea-island composite fiber part at the root of the part strongly pushes against the side of the object to be cleaned, which may be easily damaged.
又，於本發明之刷子用毛材中，作為構成上述海島複合纖維的樹脂種類，只要是包含藥劑溶解速度不同的2種類以上之樹脂，則沒有特別的限定，例如可例示上述海島複合纖維的海部包含聚酯系樹脂，且島部包含藥劑溶解速度比該聚酯系樹脂更慢的樹脂之形態。更具體而言，可例示海部包含聚對苯二甲酸丁二酯，且島部包含尼龍(註冊商標)之形態；或海部包含聚對苯二甲酸乙二酯，且島部包含聚對苯二甲酸丁二酯之形態。 In addition, in the brush hair material of the present invention, the type of resin constituting the sea-island composite fiber is not particularly limited as long as it contains two or more types of resins with different drug dissolution rates. For example, examples of the sea-island composite fiber The sea part contains a polyester resin, and the island part contains a form of a resin whose drug dissolution rate is slower than that of the polyester resin. More specifically, it can be exemplified that the sea part contains polybutylene terephthalate and the island part contains nylon (registered trademark); or the sea part contains polyethylene terephthalate and the island part contains polyethylene terephthalate. The form of butylene formate.
又，於本發明之刷子用毛材中，上述海島複合纖維的橫剖面形狀可實質上設定為任意之形狀，除了橫剖面形狀係形成圓形之形態，還可採用形成圓形以外的異形剖面形狀(例如，三角形或四角形等的多角形、多葉形等)之形態的任一者。此橫剖面形狀可因應用途或使用目的而設定。又，複數種之橫剖面形狀混合存在的使用形態亦為可能。 In addition, in the brush hair material of the present invention, the cross-sectional shape of the sea-island composite fiber can be substantially set to any shape. In addition to the shape of the cross-sectional shape being circular, it is also possible to adopt irregular cross-sections other than circular. Any of shapes (for example, polygons such as triangles or quadrangles, multi-leaf shapes, etc.). The cross-sectional shape can be set according to the application or purpose of use. In addition, a use form in which a plurality of cross-sectional shapes are mixed is also possible.
又，關於上述海島複合纖維的島部之橫剖面形狀，同樣地亦可實質上設定為任意之形狀，除了橫剖面形狀係形成圓形之形態，還可採用形成圓形以外的異形剖面形狀(例如，三角形或四角形等的多角形、Y形等)之形態的任一者。此橫剖面形狀可因應用途或使用目的而設定。又，複數種之橫剖面形狀混合存在的使用形態亦為可能。 In addition, the cross-sectional shape of the island portion of the above-mentioned sea-island composite fiber can also be substantially set to an arbitrary shape. In addition to the cross-sectional shape being a circular shape, a special cross-sectional shape other than a circular shape ( For example, any of the shapes of polygons such as triangles and quadrangles, Y-shapes, etc.). The cross-sectional shape can be set according to the application or purpose of use. In addition, a use form in which a plurality of cross-sectional shapes are mixed is also possible.
又，於本發明之刷子用毛材中，亦可將在上述海島複合纖維之端部(一端部或兩端部)外露的島部之前端部形成漸尖的錐形形狀，也可形成將海島複合纖 維中的島部之橫剖面形狀實質上維持到外露島部的前端部為止之形狀。將外露島部的前端部形成漸尖的錐形形狀之形態，例如可藉由以相對於溶解用藥劑而溶解速度較快的樹脂構成海部，以溶解速度較慢的樹脂構成島部而達成。形成將島部之橫剖面形狀實質上維持到外露島部的前端部為止之形狀的形態，例如可藉由僅海部以相對於溶解用藥劑而溶解的樹脂構成，且以相對於該藥劑而不溶解的樹脂構成島部來達成。 In addition, in the brush hair material of the present invention, the front end of the island portion exposed at the end (one end or both ends) of the sea-island composite fiber may be formed into a tapered shape with a tapered shape. Island composite fiber The cross-sectional shape of the island in the dimension is substantially maintained to the shape of the tip of the exposed island. Forming the tip portion of the exposed island portion into a tapered shape can be achieved, for example, by forming the sea portion with a resin having a faster dissolution rate with respect to the dissolving agent, and forming the island portion with a resin having a slower dissolution rate. It is formed into a form that substantially maintains the cross-sectional shape of the island part to the tip of the exposed island part. For example, it can be made of resin that dissolves only the sea part with respect to the dissolving agent, and does not correspond to the agent. The dissolved resin constitutes the island to achieve.
再者，於本發明之刷子用毛材中，上述海島複合纖維亦可具有互為不同材質的島部。更進一步，亦可成為具有互為不同的複數之橫剖面尺寸的島部之形態。如此，藉由具有複數種的島部，可使其兼具複數的機能。 Furthermore, in the brush hair material of the present invention, the sea-island composite fiber may have islands of different materials. Furthermore, it may be a form of islands having a plurality of different cross-sectional dimensions. In this way, by having plural kinds of islands, it is possible to make it have plural functions.
本發明亦提供一種刷子，其係至少一部分使用如上述的本發明之刷子用毛材。尤其，本發明之刷子由於使用如上述之不損傷被清掃物、兼具優異的清掃性、且耐久性優異、並且可得到柔軟之觸感的毛材，故特別適合作為牙刷、精密洗淨用的刷子、洗臉刷、化妝刷等。 The present invention also provides a brush, which uses at least a part of the brush hair material of the present invention as described above. In particular, the brush of the present invention is particularly suitable for toothbrushes and precision cleaning because it uses a hair material that does not damage the object to be cleaned, has excellent cleaning properties, is excellent in durability, and can obtain a soft touch. Brushes, face brushes, makeup brushes, etc.
於如此之本發明之刷子中，雖然亦取決於其用途，但作為較佳的刷子之毛長(從刷子根部到毛尖為止之長度)的範圍，可例示1~50mm之範圍，較佳為5~35mm之範圍。 In such a brush of the present invention, although it also depends on its use, the range of the hair length (the length from the root of the brush to the tip of the brush) of the preferred brush can be exemplified in the range of 1-50mm, preferably 5 ~35mm range.
如此，若依照本發明，則可提供一種刷子用毛材，其不損傷被清掃物、兼具優異清掃性、並且具有優異的耐久性。 In this way, according to the present invention, it is possible to provide a brush bristle material that does not damage the object to be cleaned, has excellent cleaning properties, and has excellent durability.

海島複合纖維4之長邊方向端部中的外露島部3a例如係以下述方式形成。海島複合纖維4由於以藥劑溶解速度(例如，因鹼處理所導致的溶解速度)不同的海部2形成用樹脂與島部3形成用樹脂之2種類樹脂所構成，故例如以作為在鹼中溶解的聚酯系樹脂之聚對苯二甲酸丁二酯(PBT)形成海部2，以作為在鹼中不溶解的樹脂之尼龍(Ny)(註冊商標)形成島部3，藉由僅指定長度的該海島複合纖維4之長邊方向端部進行鹼處理，僅使其端部部分的海部2溶解，而形成如第1圖(A)所示之具有外露島部3a的刷子用毛材1之端部部分。進行鹼處理而僅使海部2溶解、留下不溶解的島部3之處理的上述指定長度，係成為外露島部3a的外露長度。此外露長度係如前述，較佳在0.5~10mm之範圍。
The exposed
又，於本實施形態中，外露島部3a例如係由在鹼處理中不溶解的樹脂所構成，故即使因海部2之溶解而外露後，海島複合纖維4中的島部3之形狀亦照原樣留下，外露島部3a係自其根部到前端部為止，形成相同的橫剖面形狀。又，於本實施形態中，海島複合纖維4之橫剖面形狀、島部3之橫剖面形狀皆形成圓形，但如前述亦可形成圓形以外的異形橫剖面形狀。又，關於海島複合纖維4中的島部3之直徑、尤其是緊鄰外周面形成部5的島部3之直徑Di的較佳範圍、海島複合纖維4的橫剖面中之島部3之數的較佳範圍、海島複合纖維4之直徑的較佳範圍係如前述。

如上述所構成的刷子用毛材1用於各種刷子之製作係使用於至少一部分。一般而言，作為將刷子用毛材植毛於刷子構成構件時之方法，已知有代表性的二種方法，以使用於牙刷的情況為例，一邊參照第2圖一邊說明此等二種方法。 The brush hair material 1 configured as described above is used for at least a part of the production of various brushes. Generally speaking, two representative methods are known as the method for planting the brush bristles on the brush constituent members. Taking the case of using a toothbrush as an example, these two methods will be described with reference to Figure 2 .
第2圖(A)係顯示已將刷子用毛材11植毛於牙刷構成構件12之頭部的牙刷13，作為此刷子用毛材11之植毛方法，有如沿著第2圖(A)的a-a線之放大剖面圖的第2圖(B)、(C)所示的二種方法。於第2圖(B)所示的方法中，將經對折的刷子用毛材11***植毛孔14，以被稱為平線15的固定具將刷子用毛材11固定於牙刷構成構件12。所完成的牙刷通常被稱為平線牙刷。於此種平線牙刷中，預先製作的刷子用毛材11之兩端部係成為刷子之毛尖。於第2圖(C)所示的方法中，使刷子用毛材11之一端部貫穿牙刷構成構件12之頭部表面側構件12a的貫通孔16，使加熱裝置(圖示省略)碰觸已貫穿的刷子用毛材11之端部，形成被稱為燒球17的防脫落或固定用之塊，然後接合頭部背面側構件12b而隱藏燒球17，完成牙刷商品。所完成的牙刷通常被稱為無平線牙刷。於此種無平線牙刷中，預先製作的刷子用毛材11之一端部係成為刷子之毛尖。因此，將本發明之刷子用毛材1使用於平線牙刷時，上述的外露島部3a係形成在刷子用毛材1之兩端部，當使用於無平線牙刷時，外露島部3a係形成在刷子用毛材1之一端部。
Figure 2 (A) shows the
於使用上述實施形態之刷子用毛材1的刷子，如前述，係藉由細的外露島部3a存在於毛材端部之構造，而以韌性相對弱的多數之外露島部3a構成接觸被清掃物的毛尖，而變得難以損傷被清掃物，可得到柔軟的觸感，同時對於齒間等之難以清掃的細小部位也表現優異的清掃性(優異的污垢刮出性能、污垢補集性能)。而且，藉由海島複合纖維4的島部3係在該海島複合纖維4的橫剖面中，偏向存在於外周面形成部5以外之靠中央部的部位，尤其是藉由形成海島複合纖維4的外周面之僅以海部2構成的外周面形成部5之厚度Ts與緊鄰外周面形成部的島部3之直徑Di之比率Ts/Di成為1.2以上，而緊鄰外周面形成部的島部3、甚至外露島部3a，係在其根部以被充分厚度的海部2所覆蓋之狀態所支持，即使對於外露島部3a重複施加外力時，也防止因該外力所造成的支撐外露島部3a之海部2裂開，實現刷子用毛材1的高耐久性。

第3圖係顯示本發明之另一實施形態(實施形態2)的刷子用毛材21之一端部。於本實施形態中，在刷子用毛材21之端部，從海島複合纖維22外露的外露島部23其前端部形成漸尖的錐形形狀。此種形態的刷子用毛材21例如可藉由以相對於作為溶解用藥劑的鹼而溶解速度較快的樹脂(例如，聚對苯二甲酸乙二酯(PET))構成海部，以溶解速度較慢的樹脂(例如，聚對苯二甲酸丁二酯(PBT))構成島部而達成。若如此進行，則於形成外露島部23的部分中，藉由鹼處理而以快的溶解速度去
除外露島部23周圍的海部，雖然外露島部23留下，但藉由鹼處理而以慢的溶解速度被徐徐地溶解，形成漸尖的錐形形狀。又，於此海島複合纖維22之端部中，受到鹼處理之影響，於連接至外露島部23而留下的部位之海島複合纖維22的肩部，係如圖示被圓弧化，而成為更平滑的形狀。
Fig. 3 shows one end of the brush bristle
於具備此種前端部形成漸尖的錐形形狀之外露島部23的刷子用毛材21，亦與前述的實施形態1同樣地，難以損傷被清掃物，可得到柔軟的觸感，而且對於細小部位亦表現優異的清掃性，並且可得到優異的耐久性。其中關於清掃性，按照外露島部23的前端部變得尖銳的程度而對於更細小的部位亦能發揮優異的清掃效果。
