Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a shape memory yarn with built-in elasticity obtained by subjecting yarn to unique processing, and a method for producing the same.

[Conventional technology]

Conventional woolen yarn has more elongation than other fibers, but in order to further increase the elongation rate, this technique uses twisting by increasing the number of twists, but this elongation due to twisting is physical. The current situation is that the expansion and contraction rapidly decreases with repeated washing and the like.

Wool is made of layers of keratin, and this keratin is composed of more than 10 types of amino acids, of which the main ones are cystine (13.1%) and glutamic acid (12.9%).

Leucine 11.5%, Algine 10.2%, Hisdine 6
．． 9%.

Tyrosine 4.8%, Alanine 4.4%, Proline 4.4
%, etc., and are long (connected and chain-like) due to cystine bonds.

By treating the above cystine bonds with collagen derivative protein and a solution of collagen derivative protein containing keratin and hybroin solutions, this is absorbed into the wool, and it is made permanent by taking advantage of the stress caused by heating and pressurizing. It was found that crimpability was imparted to the material. The molecular structural formula of the collagen derivative protein referred to here is RCONH (RCHCON
HCH[? ) C00X X=sodium.

Potassium, ammonium, other organic amines, alcohol R-R"=C to C saturated and unsaturated fatty acids.

[Problem that the invention seeks to solve]

The present invention applies a unique process to wool to absorb collagen protein derivatives as well as collagen protein derivatives mixed with a dissolved solution of hibroin or keratin, thereby preventing a decrease in elasticity due to washing, etc., and making it permanent. The object of the present invention is to provide a shape memory wool that can provide crimpability that not only imparts stretchability but also has excellent cord properties, and a method for producing the same.

[Means for solving the problem] The above-mentioned problem is solved by the shape memory wool, which is characterized in that a collagen protein derivative or a collagen protein derivative containing a silk solution, that is, a hybroin protein solution and a keratin solution is adsorbed onto the wool. , and the above-mentioned animal protein derivative is adsorbed onto the wool, and the yarn is heated at 1,000 to 3,500T in the S or Z direction.
/M heating under moist heat conditions of 100℃ to 120℃ for 10 minutes to 1
A shape memory yarn characterized in that it is steam-set for 5 minutes and then untwisted in the opposite direction to the initial direction to impart crimpability, thereby obtaining a shape memory yarn with built-in crimps in the form of a thread or cone. This is achieved by the manufacturing method.

〔Example〕

Next, one embodiment of the present invention will be described.

A collagen protein derivative containing a collagen protein derivative as well as a solution of hybroin and keratin was absorbed into the yarn No. 60/double thread and 2,0 OOT/? in the S direction. A shape memory wool having built-in crimpability of 50% or more can be obtained by making Iti yarn, steam setting it for 10 minutes at 110° C. on the side of the twisted yarn bobbin, and decombusting it at 2,0 OOT/M in the Z direction to make it into a general shape.

This shape-memory yarn has built-in elasticity, so it is almost the same as the original yarn before processing, but if it is immersed in hot water or steam, it immediately becomes a wool with 50% more permanent elasticity and bulk. is obtained.

〔effect〕

As mentioned above, since the present invention has a built-in shape memory, it is very suitable for weaving and knitting, and also,
By treating the material with hot water after weaving and knitting, it has a high degree of elasticity in both the warp and weft directions, and can achieve physical properties with an elasticity of up to 30% for woven fabrics and 40% for knitted fabrics. As a result, we are able to produce a wide variety of high-quality products that have never existed before, such as underwear, sporting goods, and socks. Of course, dyeability, static electricity, etc. are better than before processing.
