Embodiment 1

[0071] Separately melted polyether block amide copolymer (Pebax MV1074 manufactured by Arkema) and nylon 6 (manufactured by Mitsubishi Chemical Corporation) were spun into the conjugate fiber at an area ratio of copolymer to nylon 6 of 50 / 50 ( The exposed angle is 33.5°), the cross section of the composite fiber is as follows figure 1 As shown, then take out the undrawn yarn with a monofilament fineness of 35 dtex.

[0072] The undrawn yarn was drawn at room temperature at a drawing speed of 800 m / min and a drawing ratio of 3.28 times. The drawn yarn was wound into a weft bobbin at a winding hardness ranging from 80 to 75, thereby obtaining a 22 dtex / 2f conjugate fiber for socks.

[0073] No crimp was observed in the appearance of the bobbin of the conjugated fiber, but helical crimping was observed when the fiber was detached from the bobbin for 1 to 2 minutes. The crimp rate is 62%.

[0074] The composite fiber was woven into a sock using a 4-pass seamless sock weaving m...

Embodiment 2

[0079] Socks were prepared in the same manner as in Example 1, except that the total fineness / filament count was changed to 19 dtex / 2f.

[0080] The crimp rate of the obtained conjugated fiber was 52%.

[0081] The resulting socks were well dyed and had excellent clarity and touch. The conjugate fiber according to the present invention can be used for knitting socks without any crimping treatment, and thus realizes high productivity due to its own crimping property.

Abstract

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 composite fibers for socks. Background technique [0002] Traditional socks are made from covered elastic yarn as knitting yarn. The covered elastic yarn consists of an elastic core yarn and polyamide (typically nylon 6 or nylon 66)-based filaments as the core yarn wrapped around the core yarn. [0003] But polyamide-based filaments are less hygroscopic than natural fibers, so when polyamide-based filaments are used in socks worn in contact with the skin, they can cause the wearer to feel airtight or sticky due to sweating. [0004] Polyamide-based filaments are also highly charged, so when polyamide-based filaments are used in socks, skirts tend to cling to the socks, causing serious comfort issues. A common sweat-absorbing process includes adding an organic polymer compound containing a hydrophilic group during dyeing or post-dyeing treatment. However, this method lowers the wash resistance and is not a sufficient ...
