Problems solved by technology

However, since nylon is spun at a high spinning speed above 3,000m / min, there may be a phenomenon that the yarn bends under the spinning spinneret due to a difference in relative viscosity or the spinning speed may be reduced due to a decrease in spinning speed. Problems with greatly reduced performance and yarn productivity making it difficult to produce on a commercial scale

Embodiment 1

[0042] Obtain 30mol% pyrrolidone and 70mol% caprolactam by carrying out anionic polymerization reaction, and under the spinning temperature of 260 ℃, the nylon 64 random copolymer that melting point is 170 ℃ and relative viscosity (RV) is 2.6 and relative viscosity ( Nylon 6 with an RV) of 2.6 was extruded with an extruder by a side-by-side composite spinning method. After spinning in the spinning pack in a 50:50 weight ratio, it is cooled and solidified in a cooling chamber. Winding was performed at a speed of 3000 m / min by a first guide roll and a second guide roll to prepare a half-drawn yarn of 85-denier / 24 filaments.

[0043] Utilize draw-winding machine, the above-mentioned semi-drawn yarn of winding is stretched with the spinning speed of 500m / min and the drawing ratio of 1.26, and winding 70-denier / 24 long filaments (70-denier / 24filament) specification drawing yarn to prepare nylon latent crimping yarn.

Abstract

The present invention relates to a nylon latent-crimp yarn having outstanding elastic properties and cool feel, and is characterized in that a nylon 64 random copolymer (A) and one type of polymer (B) selected from nylon 6 and nylon 66 are subjected to conjugate spinning on a yarn cross-section in a side-by-side form. The nylon latent-crimp yarn according to the present invention has outstanding dyeing properties, dye fastness and elasticity, and exhibits high official moisture regain and a good cool feel. Also, the nylon latent-crimp yarn according to the present invention is inexpensive to produce, is highly suited to production, and also has outstanding yarn uniformity. For this reason, the nylon latent-crimp yarn according to the present invention is particularly useful as a fabric material for outdoor wear which is used like an elastic breathable waterproof polyurethane film.

Description

technical field [0001] The present invention relates to a nylon latent crimp yarn (nylon latent-crimp yarn) with excellent elasticity and cool feeling, especially relates to a kind of (i) nylon 64 random copolymer and (ii) nylon 6 or nylon 66 polymers are composite-spun in side-by-side form on the cross-section of the yarn, which has excellent elasticity and cool nylon latent crimping yarn, thus providing excellent dyeing performance, color Fastness and elasticity, and exhibit high public moisture regain and good cool feeling. Background technique [0002] Nylon stretchable yarns are produced using similar techniques to polyester stretchable yarns. However, in terms of the purpose of use, polyester-based stretchable yarns are mainly widely used in T-shirts, jackets, trousers, etc., and have recently been used as composite yarns with other materials. However, nylon stretchable yarn is mainly used for outdoor wear, underwear and socks, so there is a difference in terms of us...
