Invention Titlel A DOUBLE-COVERED LYCRA SOFT YARN
(Technical Field]
This invention relates to the yarn for knitting socks, especially, the polyurethane based Lycra Soft 520 denier for the prevention of twist and maintenance of elasticity after processing.
By double covering the polyurethane based Lycra Soft 520 denier yarn with nylon 70D/24F/1 high sped textured, applyjng S twist and Z twist at the same time to prevent twisting, maintain the elongation rate of the Lycra Soft 520 denier yarn at proper value while utilizing the maximum restitution.
When the said nyhn 70D/24F/1 high speed textured yarn(20, 30) is wound first in S
twist(842,8TPM) and second in Z twist(1960.8TPM ), the Lycra Soft 520 denier yarn, which is the core yarn, gives the elongation rate(tensile elongation 440.9%, permanent elongation 7.2%, restitution rate 98.2%) which is lower than the original value.
(~3ackground Aft]
To produce polyurethane based Lycra Soft 520 denier yarn double covered with nylon.
(Disclosure]
[Technical Pxoblem]
Generally speaking, core yarn used for producing socks has been used with special yarn feeding devices which incorpprate anti-slip device for polyurethane yarn, without any specific processing, dud to the high elasticity.
The socks produced in this method present the characteristics of the Lycra Soft 520 denier yarn which has a stronger restitution and elongation than common yarn.
However, sometimes it is necessary for the socks made with Lycra Soft 520 denier yarn to be restricted in its elongation rate, especially for leisure - sports activity socks, which has not been possible in conventional ways.
In addition, due to the structural characteristics of the elastic thread feeding device of common sock knitting machines, it is difficult to design knitting with Lycra Soft yarn which is liable to slip at #eeding.
The technical goal of this invention is to produce polyurethane based Lycra Soft yarn double covered with nylon, for the prevention of twisting and maintenance of elasticity after processing.
Technical Solut~onl In this invention, it is possible to replace the said nyion high speed textured yarn with any one of polyamide, polyester, or polypropylene fiber which are filament yarn or long staple, or with a long staple copolymer yarn.
As described hereinabove, by double covering the polyurethane based Lycra Soft 520 denier yarn wi~~h nylon 70D/24F/1 high speed textured, applying S twist and Z twist at the same time to prevent twisting, maintain the elongation rate of the Lycra Soft 520 denier yarn at proper value whFle utilizing the maximum restitution.
When the said nylon 70D/24F/1 high speed textured yarn(20, 30) is wound first in S
tw~st(842.8TPM) and second in Z twist(1960.8TPM ), the Lycra Soft 520 denier yarn, which is the core yarn, gives the elongation rate(tensile elongation 440.9%, permanent elongation 7:2%, restitution rate 98.2%) which is lower than the original value.
In order to accomplish the strength of sock parts in accordance with the shape of leg using Lycra Soft 520 denier yarn, processed by this invention, the feeding speed of the yarn into knitting machine with the double covered yarn roller, which is provided in most machines, and the stepping. motor_ Finished socks, as well as similar products, are heat treated(approximately for 40-50 minutes at 90=100 C) after dyeing in order to give high elasticity to the Lycra Soft 520 denier yarn double covered in accordance with this invention, and to strengthen the compression property of the prqduct by contracting the nylon 70D/24F/1 high speed textured yarn.
In addition, the surface of the nylon 70D/24F/1 high speed textured yarn covering the Lycra Soft 52p denier yarn becomes smoother by the heat contraction, giving better wearing sense and the structural stability of the product, providing the elasticity and compression better than a corppress.
As for the knitting method, the core yarn produced by the art of this invention is not only used in a Specific part of socks but used in all the part of socks except the toe and heel. The partial compression according to the shape of leg is controlled with the double covered yarn roller and the stepping motor which are installed at most sock knitting machines.
