Which is obtained by melt-spinning the above, wherein the average diameter of the island component in the fiber cross section is less than 1 μm.

い。The polymer of the island component has a shape similar to an elongated capsule of the drug in the fiber, and the diameter of the fiber cross section having a fineness of about 12d is less than 1 μm, that is, the volume of one island component is approximately. It is preferably less than 10 μm 3 , and the presence of an island component having a diameter of more than 3 μm in the fiber cross section is not preferable because the fiber moldability is deteriorated.
【０００９】島成分の種類は海成分のポリマーと異なっ
ていれば特に限定されるものではない。The type of island component is not particularly limited as long as it is different from the polymer of the sea component.

合体、およびこれらの変性体などが挙げられる。Particularly when polyolefin is used as the sea component, if a dyeable polymer is used as the island component polymer, both anti-pilling property and dyeability can be made to exist together. For example, when at least one polymer selected from polyamide and / or polyester and copolymers thereof is used as the island component, it can be dyed with a disperse dye or the like under ordinary dyeing conditions. Specific examples include homopolymers and copolymers of polyamides such as thermoplastic nylon 6, nylon 66 and nylon 12 and polyesters such as polyethylene terephthalate and polybutylene terephthalate, and modified products thereof.

Fibers made by melt spinning a polymer alloy of 2 or less are
Since it is light and vulnerable to impact, it is thought that it will fall out immediately even if pilling occurs. Therefore, the smaller the Izod impact strength is, the more the anti-pilling property is improved. However, it is preferable that the Izod impact strength is 2 kg-cm / cm 2 or more in molding the fiber.

As a method for reducing the amount to 2 or less, there is a method of adjusting the type and the amount of the compatibilizer added during the production of the polymer alloy. The compatibilizer is used for compatibilizing the sea component and the island component, that is, for making them compatible with each other and finely dispersing the island component in the sea component. The type of compatibilizer determines the degree of compatibilization between sea-island components. And, the greater the amount added, the more compatibilized.

添加量を決定する必要がある。The Izod impact strength changes depending on the degree of compatibilization between the sea-island components, and the weaker the degree of compatibilization, the smaller the Izod impact strength. However, as described above, if the Izod impact strength becomes too small, the fiber moldability becomes poor. Therefore, there is a fiber moldability, and the polymer of the sea component and the island component is adjusted so that the Izod impact strength is 7 kg-cm / cm 2 or less. The type of compatibilizer depending on the type,
It is necessary to determine the addition amount.

Using a polymer alloy having a combination of T S <T I , T I +
It is more preferable to adopt the range of 5 ≦ T ≦ 320. If the spinning temperature exceeds 360 ° C, the sea component polymer is decomposed, which is not preferable. Considering the heat resistance of various stabilizers in the sea component polymer, 320 ° C or lower is more preferable. The melt viscosity of the polymer alloy used is 1 at the melt flow rate (MFR; g / 10 min) measured according to JIS K7210 (weighting 2169 g) in which the spinning temperature is the measuring temperature.
0 ≦ MFR <300 is convenient, and a fiber fineness of 0.5 to 2 denier is preferably 10 to 30 g / 10 minutes, and a thick fineness of 15 to 30 denier is preferably around 10 g / 10 minutes. MFR
In the case of> 300, it is preferable to lower the spinning temperature and form the fiber because the fluidity is excessive and the fiber formability is lost.

た。[Comparative Examples 5 to 7] 20 parts by weight of a compatibilizing agent was added to 100 parts by weight of nylon, a polymer alloy of polypropylene and nylon was prepared in the same manner as above, and melt-spun. Made with fiber. After that, as a spun yarn, this was made into a knit fabric made by plain knitting, and the pilling test of this knit fabric was conducted by the same method as above.

察した。Table 1 shows the fiber performance, dyeability, and pilling test results of Examples 1 to 3 and Comparative Examples 1 to 7. In Table 1, the spinnability was evaluated as × when the unstretched yarn of 12d could not be pulled off. In that case, the unstretched yarn was pulled by hand and the cross section was observed.
