The present invention relates to a core-sheath type composite fiber having friction-resistant melting performance that solves problems.

Description of the Related Art A cloth made of synthetic fibers such as polyester and nylon, which is used as sports clothing, slides on the floor surface, and when excessive friction occurs, it is melted by the generated friction heat to cause holes. Therefore, various friction-resistant melting processes are performed.

洗濯により性能劣化はまぬがれないものである。Surface treatments such as adding smoothing agents containing silicone as a main component to improve the smoothness of the cloth have been carried out. Such special processing methods show good friction melting resistance, but snagging, etc. However, the physical properties of the fabric are deteriorated, and the performance deterioration cannot be prevented by washing.

However, in this case, there is no doubt that the synthetic fibers in the surface layer are melted by friction, and there are also problems such as the color resistance of cotton and the high cost based on the processing labor.

Japanese Patent Laid-Open No. 4-11006 proposes a core-sheath type composite spun fiber in which a polymer having a lower melting point than a polymer of a sheath component is used as a core component. That is, this fiber is a composite spun fiber in which polyethylene terephthalate is arranged as the sheath component and polypropylene or nylon 12 is arranged as the core component.

供することを目的とする。Further, in order to improve the resistance to frictional melting, a plasticized low melting point nylon 12 or nylon 6/12 copolymer showing a melting point lower than that of nylon 12 is adopted as the core component polymer. It was revealed that the friction-melting performance was not so expressed. The present invention improves on the conventional technique disclosed in Japanese Patent Laid-Open No. 4-11006, and further enhances friction melting resistance.
It is an object to provide a fiber which hardly shows a trace of melting even when it is rubbed under pressure.

耐摩擦溶融性能を有する芯鞘型複合繊維である。The gist of the present invention is that the core component polymer has a lower melting point than the sheath component and has a heat of fusion of 9
It is a core-sheath type composite fiber having anti-friction melting performance, which is a polymer having 0 J / g or more.

It has been known that the core-sheath type composite spun fiber in which 2 is arranged exhibits good friction melting resistance.

7.6 J / g) or nylon 6/12 copolymer (melting point = 147.1 ° C., heat of fusion = 43.4 J / g) is used as the core component polymer, and the core-sheath type composite spun fiber has anti-friction melting performance. By using a polymer having a low melting point and a heat of fusion of 90 J / g or more as a core component polymer, which is not so much improved, a fiber excellent in friction melting resistance as the object of the present invention is obtained.

J / g) and nylon 6 (melting point = 224 ° C., heat of fusion = 67 J / g) can be used, but a polyester polymer whose main repeating unit is a repeating unit of polyethylene terephthalate is preferably used.
On the other hand, as a core component polymer, high-density polyethylene having a melting point lower than that of the sheath component polymer and a heat of fusion of 90 J / g or more (melting point = 130 ° C., heat of fusion = 135 J / g
g) can be used. As core components, low-density polyethylene (melting point 114 ° C, heat of fusion 77J / g), polypropylene (melting point = 168 ° C, heat of fusion = 81J / g)
Or nylon 12 (melting point = 182 ° C., heat of fusion = 5
When 5 J / g) or the like is used, the friction-melting performance is exhibited to some extent, but even if it is subjected to the contact pressure rubbing, which is the object of the present invention, it does not become a fiber having almost no trace of melting.

る。The reason why the composite fiber of the present invention exhibits excellent friction-melting resistance is not clear, but the heat generated by friction causes the temperature of the core to rise to around its melting point, and the core tries to melt. It is considered that the temperature rise of the sheath is suppressed by the melting endothermic action that occurs at this time, and nylon 12 having a larger heat of fusion than that having plasticized nylon 12 having a small heat of fusion or a copolymer as a core component is It can be fully understood from the fact that the performance is exhibited more.

熱量が大きく性能発現性も大きい。Further, from this, as a method of further enhancing the performance expression, a polymer having a lower melting point and a larger heat of fusion (90 J / g or more) than the sheath component polymer is effective for the core component polymer, for example, high density. Polyethylene has a larger amount of heat of fusion than polypropylene or nylon 12, and has a greater performance manifestation property.

Using this false twist textured yarn, knitting was performed with a mock lodie, which is a typical structure when used for sports clothing with a 20G circular knitting machine, and dyeing finish was carried out in a usual dyeing process adopted when using polyester fiber. A fabric with good color clarity and texture was obtained. When the rotor type friction melting test (load 6 kg, 3 seconds) was performed on the obtained fabric, almost no melting trace was observed and no perforation phenomenon was observed.
