Embodiment 1

[0124] Nylon MXD6 having a relative viscosity of 2.7 and nylon 6 having a relative viscosity of 3.0 were mixed at a weight ratio of 50:50 to obtain a polyamide resin composition as component A. In addition, polyethylene terephthalate having an intrinsic viscosity of 0.61 was used as the B component.

[0125] According to the ratio of A component: B component volume ratio is 1: 2, under the condition of spinning temperature 295 ℃, spinning speed 1500m / min, carry out melt composite spinning in the mode that A component constitutes the radial part, obtain almost the same as Figure 4 Undrawn filaments of the same cross-section. At this time, component A is supplied to a metering pump through a static mixer after being melted. Then, the obtained undrawn yarn was drawn under the conditions of a roller heater of 85°C, a plate heater of 150°C, and a drawing speed of 2.50 times to obtain a split-type conjugate fiber of 110dtex / 50f.

[0126] Then, using this drawn yarn, a tube knitti...

Embodiment 2、3

[0129] [Example 2, 3, Comparative Example 1, 2]

[0130] Except for changing the weight ratio of nylon MXD6 and nylon 6 which are polyamide components, fibers were produced by the method described in Example 1, and various evaluations were performed.

[0131] [Table 1]

[0132]

Embodiment 4

[0144] Except that the B component was made of polypropylene, and the treatment method was immersion in 98° C. hot water for 10 minutes, fibers were produced by the method described in Example 1, and various evaluations were performed. The results are shown in Table 2.

[0145] Due to the low adhesion between polyolefin and polyamide, it is easy to use hot water to cut fiber and shrink. Moreover, a product with soft touch and good bulkiness was obtained.

[0146] "Example of wiping performance"

[0147] Examples regarding wiping performance are further specifically cited. However, the present invention is not limited to the Examples described below.

[0148] A. Intrinsic viscosity of polyester

[0149] Intrinsic viscosity [η] is measured in a mixed solvent of phenol / tetrachloroethane=6 / 4 (weight ratio) at 20° C. using an automatic viscometer by a usual method.

[0150] B. Relative viscosity of polyamide

[0151] The relative viscosity ηrel is measured in a sulfuric acid so...

Abstract

A splittable conjugate fiber for obtaining a fiber structure excellent in denseness and bulkiness includes a polyamide resin composition and a fiber-forming polymer not having an affinity with the polyamide resin composition. The polyamide resin composition and the fiber-forming polymer are combined with each other in a fiber longitudinal direction. The polyamide resin composition contains aromatic polyamide and aliphatic polyamide. Preferably, the aromatic polyamide is a nylon MXD6 polymer, and the aliphatic polyamide is a nylon 6 polymer.

Description

technical field [0001] The present invention relates to a split-type conjugate fiber composed of a fiber-forming polymer having no affinity for polyamide such as polyamide and polyester, and to a fiber structure and a wiping cloth using the split-type conjugate fiber. Background technique [0002] The split-type conjugate fiber is a composite fiber obtained by composite spinning of two or more polymers. After being made into a fabric, the composite fiber is split or the like to obtain a fiber structure, which can be used in various applications. [0003] In particular, split-type conjugate fibers made of polyester and polyamide are easy to obtain a fiber structure with excellent bulkiness and flexibility, so they are suitable for various applications such as clothing materials such as suede fabrics, and materials such as wiping cloths. use. In addition, as a wiping cloth, it is suitable for wiping purposes such as cleaning precious metals and mobile phones, and polishing an...
