Benefits of technology

[0013]According to the present invention, it is possible to provide conjugate fibers for stockings, having high transparency and soft texture due to high crimping property, high productivity because of no need for wooly processing, and superior water-absorbing property, hygroscopicity, antistatic property, and cool feeling.

Problems solved by technology

However, the polyamide-based filaments have low hygroscopicity as compared with natural fibers and therefore, when the polyamide-based filaments are used in stockings which are worn in touch with skin, they can cause the wearer stuffy or sticky feel due to perspiration.
The polyamide-based filaments also have high charging ability and therefore, when the polyamide-based filaments are used in the stockings, a skirt tends to cling to the stockings, which causes serious comfort issues.
However, this method provides reduces washing durability and is not enough solution.

example 1

[0055]a polyether block amide copolymer (Pebax MV1074 manufactured by Arkema) and nylon 6 (manufactured by Mitsubishi Chemical Corporation) which were melted separately were spun into a conjugate fiber (an angle of exposure was 33.5°) at an area ratio of the copolymer to nylon 6 of 50 / 50, the conjugate fiber having the cross-section shown in FIG. 1, and then the undrawn yarn having the single filament fineness of 35 dtex was taken up.

[0056]The undrawn yarn was drawn at room temperature under the condition of a draw speed of 800 m / minute and a draw ratio of 3.28 times. The drawn yarn was wound into a pirn at a winding hardness in the range of 80 to 75, thereby a 22 dtex / 2f conjugate fiber for stockings was obtained.

[0057]No crimp was observed in the appearance of a cop of the conjugate fiber, but when 1 to 2 minutes had passed since the fiber was released from the cop, spiral crimps were observed. The percentage crimp was 62%.

[0058]The conjugate fiber was knitted into stockings using...

example 2

[0062]Stockings were prepared in the same manner as in Example 1, except that the total fineness / the number of filaments was changed to 19 dtex / 2f.

[0063]The obtained conjugate fiber had a percentage crimp of 52%.

[0064]The obtained stockings were well dyed and excellent in transparency and touch. The conjugate fiber according to the present invention could be used for knitting stockings without any crimp processing because of its crimp characteristic, thereby high productivity was achieved.

Abstract

(A1) Translate this text A composite fiber for stockings which has water-absorbing properties, hygroscopicity, antistatic properties, crimp properties, and cool touch is obtained without sacrificing productivity, transparency, and soft touch. The composite fiber for stockings is an eccentric composite fiber comprising a fiber-forming resin (B) and a polyether block amide copolymer (A). The fiber is characterized in that the polyether block amide copolymer (A), in a cross section of the fiber, is exposed in the surface at an angle of 5-90, and the fiber has 1-10 filaments and a fineness of 1-55 dtex. The fiber especially preferably has a percentage crimp of 10% or higher.

Description

TECHNICAL FIELD[0001]The present invention relates to the conjugate fibers for stockings.BACKGROUND ART[0002]Conventional stockings are made of covered elastic yarn as knitting yarn. The covered elastic yarn is composed of an elastic core yarn and polyamide (typically such as nylon 6 or nylon 66)-based filaments as a covering yarn wound around the core yarn.[0003]However, the polyamide-based filaments have low hygroscopicity as compared with natural fibers and therefore, when the polyamide-based filaments are used in stockings which are worn in touch with skin, they can cause the wearer stuffy or sticky feel due to perspiration.[0004]The polyamide-based filaments also have high charging ability and therefore, when the polyamide-based filaments are used in the stockings, a skirt tends to cling to the stockings, which causes serious comfort issues. A general sweat absorption processing includes adding an organic polymer compound containing hydrophilic groups during dyeing or a post tr...
