Problems solved by technology

However, in order to obtain a sufficient cold feeling to the touch, it must contain a large amount of porous inorganic powder particles, as a result, it will adversely affect the hand feel or skin touch, and it is a fiber that cannot be used for undershirts, etc.

Embodiment 1

[0118] With respect to 98% by weight of a polyether block amide copolymer (manufactured by Arkema, "Pebax 1041SA01") which is a thermoplastic polyamide-based elastomer, titanium oxide (manufactured by Sakai Chemical Industry Co., Ltd., "D918") was added, with an average particle diameter of 0.26 μm ) after 2% by weight, melt-mixing, and using a pelletizer to obtain resin pellets.

[0119]Next, the obtained resin pellets were spun by a melt spinning method to obtain a raw yarn. Gray cloth is produced by weaving using the obtained raw yarn.

Embodiment 2

[0121] In addition to making the addition amount of polyether block amide copolymer (manufactured by Arkema, "Pebax 1041SA01") 96% by weight, the addition amount of titanium oxide (manufactured by Sakai Chemical Industry Co., Ltd., "D918", average particle diameter 0.26 μm) was Gray fabrics were obtained in the same manner as in Example 1 except for 4% by weight.

Embodiment 3

[0123] Except that the addition amount of polyether block amide copolymer (manufactured by Arkema, "Pebax1041SA01") was 94% by weight, the addition amount of titanium oxide (manufactured by Sakai Chemical Industry Co., Ltd., "D918", average particle diameter 0.26 μm) was 6 Gray fabrics were obtained in the same manner as in Example 1 except for weight %.

Abstract

The object of the present invention is to provide a fiber with an excellent cool feeling to the touch, which can prevent uncomfortable feeling when wet, and has an excellent hand or skin touch, and a fabric, clothing, and singlet with an excellent cool feel to the touch made of the fiber with an excellent cool feel to the touch . The present invention is a fiber that contains a thermoplastic elastomer and an inorganic filler and is excellent in cold feeling to the touch.

Description

technical field [0001] The present invention relates to a cool-to-touch fiber capable of preventing discomfort when wet and excellent in hand or skin touch, and gray fabrics, clothing, and singlets made of the cool-to-touch fiber. Background technique [0002] In recent years, as undershirts for summer, undershirts using fibers excellent in coldness to touch that induce a cool feeling when worn and provide a cool feeling have been studied. [0003] As a method of producing such a fiber excellent in coolness to touch, for example, a method of improving the water absorption of the fiber or improving the heat conductivity of the fiber has been implemented in the past. [0004] Examples of fibers having improved water absorption include fibers containing resins into which hydrophilic groups such as carboxyl groups and hydroxyl groups have been introduced. [0005] Examples of fibers with improved heat conductivity include fibers containing a resin mixed with a filler having hig...
