Description
(I) a nylon 64 random copolymer and (ii) a nylon 6 polymer or a nylon 66 polymer in a side by side manner on a yarn cross-section. The present invention relates to a nylon latent bulb excellent in stretchability and cold feeling, To a stretchable nylon pottery having excellent dyeability, fastness to dyeing and stretching, and high process water content and exhibiting good cooling feeling (Cooling touch).
Nylon stretch yarn has similar production technology to polyester stretch yarn. However, polyester type stretchers are widely used for t-shirts, jackets, pants, etc. and are used for composite yarns with other materials recently. However, nylon stretch yarns are mainly used for outdoor wear, innerwear and socks And has a difference in usage.
However, when used as a material for fabrics used in stretch breathable and waterproof polyurethane films, polyester high-density housing has problems in dyeing fastness, durability, frictional resistance and cold feeling.
As a result, in recent years, the use of nylon stretch yarns in outdoor wear materials has increased significantly.
As a first conventional technique for producing a nylon stretch yarn, there has been used a method of producing nylon 66 stretch yarn by stretching nylon 66 at a high temperature during the twisting process and subjecting it to a twist treatment.
The above-mentioned conventional method is a method in which a nylon 66 hardened yarn (POY) having a high melting point is subjected to a low-speed twisting at a high temperature, such as a pin tilting method or a disk tilting method, to form a crimp by a physical method on an unoriented yarn, It has a climatic rate and exhibits stretchability on the fabric.
However, since the nylon 66 is not produced domestically for clothing but is imported at a relatively high price compared to nylon 6 due to hexamethylenediamine, which is a high-priced raw material, the manufacturing cost is increased and the productivity is low at high temperature There is a problem that the probability of occurrence of unevenness of the yarn is increased due to falling and high climp at high temperature.
As a second conventional technology for producing a nylon stretch yarn, there is a method of producing a nylon latent nest by co-spinning a nylon 66 polymer and a nylon 6 polymer having a shrinkage ratio of about 4 to 5% Has been used.
However, since the difference in shrinkage ratio between the nylon 66 polymer and the nylon 6 polymer is as low as about 4 to 5%, the second conventional method has a problem in that it is difficult to manifest the natural crimp and the occurrence of the crimp on the fabric is remarkably lower than the occurrence of the crimp in the yarn state.
As another conventional technique for producing a nylon stretch yarn, there is also used a method of producing a nylon latent housing by co-spinning a nylon polymer having a different relative viscosity (RV) on a cross section of a yarn side by side, Minute, it is difficult to commercialize it because of the difference in relative viscosity between the lower part and the lower part of the cage.
Disclosure of the Invention The object of the present invention is to solve the problems of the prior art described above and to provide a nylon potential housing having excellent dyeability, fastness to dyeing and stretching, high process water content and good cold feeling and excellent yarn uniformity, .
In order to achieve the above object, in the present invention, one kind of polymer (B) selected from nylon 64 random copolymer (A), nylon 6 and nylon 66 is used as a side-by- To produce a nylon pottery barn.
The nylon 64 random copolymer (A) is composed of 10 to 30 mol% of pyrrolidone as a nylon 4 monomer and 70 to 90 mol% of caprolactam as a nylon 6 monomer.
INDUSTRIAL APPLICABILITY The latent nylon housing according to the present invention exhibits excellent cold feeling due to excellent dyeing property, dyeing fastness and stretchability and high process water content.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional schematic view of a nylon latent housing according to the present invention;
Figure 3 is an electron micrograph of a nylon latent barn of the present invention before weaving and processing.
FIG. 4 is an electron micrograph of a nylon latent barn of the present invention which has been woven and processed. FIG.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
The nylon latent housing according to the present invention is characterized in that the nylon 64 random copolymer (A) and one kind of polymer (B) selected from nylon 6 and nylon 66 are side-by-side Side-by-side manner.
Figures 1 and 2 are schematic cross-sectional views of a nylon latent housing according to the present invention.
The nylon 64 random copolymer (A) is composed of 10 to 30 mol% of pyrrolidone as a nylon 4 monomer and 70 to 90 mol% of caprolactam as a nylon 6 monomer, and has a molecular weight of 70,000 to 120,000 g / The polydispersity index is 1 to 2.
The nylon 64 random copolymer (A) is prepared by anion addition polymerization of caprolactam and 2-pyrrolidone, has a low crystallization degree of 50% or less, has a low melting point and a high water content and is difficult to use as an engineering plastic. And is suitable for use in clothes.
Nylon 46 polymer, on the other hand, is produced by the polycondensation of 1,4-diaminobutane and adipic acid and has the highest crystallization rate, high melting point, excellent friction resistance, low deformation coefficient, oil and grease And is mainly used as engineering plastics.
The present invention relates to a nylon 64 random copolymer (A) having a side-by-side composition radially spread on a cross section of a yarn, wherein the weight ratio of one kind of polymer (B) selected from nylon 6 and nylon 66 is 25 to 50:75 to 50 .
The nylon latent housing according to the present invention has boiling shrinkage of 30 to 50%, climbing rate of 20 to 50% and process water content of 5 to 8%.
The nylon 64 random polymer (A) has a relative viscosity (R, V) of 2.4 to 3.0 as measured by a sulfuric acid viscosity method, a melting point of 150 to 190 캜, and a specific gravity of 1.11 to 1.13 g / cm 3.
The one kind of polymer (B) selected from nylon 6 and nylon 66 has a relative viscosity (RV) measured by sulfuric acid viscosity method of 2.4 to 2.7.
The nylon 64 random copolymer (A) is obtained by anionic or bulk polymerization at a ratio of 70 to 90 mol% to 10 to 30 mol% of caprolactam, which is a monomer of nylon 6 polymer, and pyrrolidone, which is a nylon 4 polymer monomer. As the molar ratio of caprolactam increases, the properties of nylon 6 become stronger, and the effect of increasing the melting point of the nylon 6 is increased, but the process water content is decreased, which is the same as that of ordinary nylon 6 and nylon 66. Pyrrolidone can be obtained by degradation of the enzyme from cellulose, and is also known as a bio-based material. Nylon 4 is a polymer of butanolactam [also called butylolactam, 2-pyrrolidinone, α- or 2-pyrrolidone], which is a polymer of 2-pyrrolidone ring opening under certain conditions. ≪ / RTI > The high shrinkage polymer thus produced has a boiling shrinkage of 30% to 60% at the time of spinning as a general yarn, and has a melting point of 150 to 190 ° C and a relative viscosity (RV) of 2.4 to 3.0 as measured using a sulfuric acid viscosity method . Since the relative viscosity has a relative viscosity similar to that of nylon 6 and nylon 66, the radioactivity in the production of the pottery barn is improved, and the yarn can be produced without major modification even by using the existing composite spinning facility.
Pyrrolidone, a nylon 4 monomer, is a bio-based material and can be used as an environmentally friendly material. Consumers are increasingly interested in eco-friendly materials in the high oil price era due to the depletion of fossil fuels. Also, by using it for clothing, it has the image that it does not destroy the natural environment, and it is suitable as a fiber to be used in the future where resource exhaustion is expected.
However, since pure nylon 4 has a high melting point, the processing temperature and the decomposition temperature for melt spinning are very close to each other. Also, because of its high moisture content, it was not suitable for engineering plastics.
When using nylon 4 for clothing, the amide group contains a lot of contrast with ordinary nylon, and the hydrophilic nature is strong. Accordingly, the present invention provides a nylon 64 random copolymer obtained by copolymerizing nylon 4 and nylon 6 at a certain ratio, thereby lowering the melting point to ensure a processing temperature and controlling crystallinity, thereby exhibiting high shrinkage performance. When a high shrinkage polymer which is a copolymer of nylon 4 and nylon 6 is used and a side-by-side composite spinning is used, the high-shrinkable polymer exposed on the surface increases the moisture content, and when the skin comes into contact with human skin, , And because of its high moisture content, it can feel comfort. In addition, by absorbing and retaining the moisture of human skin, it not only feels comfortable all the time, but also can express cold feeling due to high moisture content compared to ordinary nylon in summer. Generally, the cold skin is more expressed in the cellulose-based fibers.
In addition, nylon 64 random copolymers are stable in radioactivity, have a low radiation temperature, and when irradiated with nylon 6 rather than nylon 66, radiation can be achieved at low radiation temperatures, which can also result in energy savings.
In the case of nylon 64 and nylon 610 copolymerized with the same molar amount of nylon 6 and nylon 4, such high accumulation characteristics do not appear and the moisture content is rather low. However, in the nylon 64 random copolymer, As a result, when the side-by-side composite spinning is performed, a lot of shrinkage occurs in the form of bimetallic toward the nylon 4 copolymer, which can produce the same effect as latent crimping. When a difference in shrinkage ratio is obtained by processing, a spiral-like structure is formed by a yarn of spiral structure, and a fabric having stretchability can be produced through shrinkage processing at the time of processing immediately after the fabric is finished. In addition, the two polymers can be dyed with acid dyes based on nylon series, and contain a large amount of amine groups as dyeing seats, making it possible to produce latent housing with excellent dyeability and fastness.
Hereinafter, the present invention will be described in detail with reference to examples and comparative examples.
However, the scope of protection of the present invention is not limited to the following examples.
