Description

 Bamboo and silk mixed yarn, and fabric formed by the same

The present invention relates to a bamboo-silk composite yarn and a bamboo-silk mixed fabric using the same, and more particularly, to a composite yarn made of naturally degradable bamboo fibers and silk fibers having excellent antibacterial and refreshing feel, and a bamboo-silk mixed fabric using the same. It is about.

Bamboo is found to be 10 ℃ lower than the average human body temperature, giving it a refreshing feeling in summer, and inhibiting bacterial infections and removing odors. Therefore, in Korea, bamboo has been cut into small sizes and weave together or split into thin pieces.

       In addition, bamboo, a natural material, is environmentally friendly because it can decompose naturally and absorbs and releases sweat to maintain a pleasant atmosphere, which is beneficial to the human body. It is thought that it can be a material, but in order to be applied as a garment, it is necessary to meet the basic conditions that can be made of fiber, and until now, the manufacturing process of the fiberization furnace is difficult, and has been mainly applied to manufacturing fillers or molded bodies.

In recent years, as people's lives have improved, natural fiber, which is beneficial to health, has become popular due to the well-being craze that is popular all over the world. Accordingly, fiber of various natural materials such as soybean fiber and corn fiber, which was not used much in the past, is being developed. In addition, bamboo fiber, which is effective in suppressing bacterial infections and odors and above all, absorbs and releases sweat quickly, is not an exception. Is leaning.

However, it was difficult to fiberize bamboo, and even when it was fiberized, there were many lint, so that weaving and cutting were often difficult in the canonical or braided or twisted yarn process, and weaving was very difficult. Therefore, bamboo yarn, which is applied for clothing, must firstly reduce wool and meet yarn length, toughness and elasticity, so that it is manufactured with a twisted yarn of nearly 1000 T / M. Therefore, the common bamboo yarn has the advantage of giving a good fit and cool feeling because it does not adhere to the body with the unique texture of the lecturer, but it is difficult to blend or mix with other companies as described above, and also tend to shrink after weaving or knitting, and There were many lint-free problems that could be solved for high-quality fabrics.

Therefore, measures to facilitate the weaving and knitting while utilizing the characteristics of bamboo have been devised. For example, a method of mixing with other fibers has emerged. However, bamboo yarns have not been developed so far to improve the refreshing feel of bamboo fibers and facilitate the spinning and weaving or knitting process and increase the wearing comfort.

On the other hand, silk is a representative natural fiber, cool in summer, warm in winter, breathable, unique, elegant gloss, soft and light, and as a high quality fiber, it is still firmly in the leading position even now. However, when it is made of pure silk fiber, wrinkles are well and it is difficult to preserve the shape during moisture or water washing, and the yarn price is expensive, which is not practical.

The present inventors have also developed natural health fibers that can exhibit optimal properties by mixing with bamboo fibers made of lecture yarn for many years.As a result, when the silk fiber is properly mixed and manufactured into composite yarns, each of bamboo and silk It has been found that health fabrics with unique textures, freshness and antibacterial properties can be produced by further enhancing their properties and at the same time complementing their shortcomings.

In other words, according to the present invention by mixing silk fibers in bamboo fibers to produce a composite yarn, by increasing the durability and elasticity by reducing the lint of the bamboo fibers to reduce the volume of the bamboo fibers, as well as increase the durability, weaving and dyeing It solves problems in the pretreatment process, improves work efficiency, maximizes the advantages of bamboo fiber and silk fiber, has antibacterial and deodorizing effect, absorbs sweat quickly and radiates to the outside, so it is always pleasant and cool. We have developed a low-cost, practical, biodegradable, environmentally friendly fabric that is very beneficial for water-laundering.

According to the present invention, in the bamboo-silk composite yarn using bamboo fiber that can be optimally applied as a fabric and mat, or wallpaper for clothing,

The bamboo yarns made of lecture yarns of 1000-3000T / M are screened, and the silk yarns surround the bamboo screenings as external yarns, and the silk yarns in the longitudinal direction range from 5-80% by weight based on the total weight of the yarns. It is characterized by being mixed within.

In addition, the bamboo-silk composite yarn according to the present invention is made of bamboo twisted yarn doubling and twisting (twisting) to the twisted yarn of silk yarn 2-4 strands, the silk yarn in the total length direction 5 It is also characterized by being mixed within the range of -80% by weight.

Furthermore, according to the present invention, any one of the composite yarns as warp or weft, or warp and weft yarns, weaving or knitting the composite yarn into warp knitting or weft knitting, and the silk fiber as a whole is 5 to 80 weight per unit area of the total fabric. By blending in the range of%, it reduces the lint of bamboo fiber and greatly improves toughness, and it is an antimicrobial and deodorizing effect and breathability, and it has an elegant luster and excellent absorbency, moisture permeability and form stability. It is characterized by providing.

Silk yarn used in the present invention is applied to the raw yarn, spun silk, or doxa (doupion silk), and the like, and the sericin-fixed silk also varies depending on the texture and atmosphere required in the final fabric. It can be applied, and the toughness of the whole yarn varies according to the applied content, and if the amount of silk fiber is large, the heat retention is increased, so it is possible to use it as winter clothing.

Bamboo yarn is manufactured as a twisted yarn of 1000-3000T / M after passing through pre-treatment, decomposition and deguming, fiber forming process and post-treatment according to a conventional method.

Referring to the accompanying drawings, a bamboo-silk composite yarn according to the present invention and a bamboo-silk mixed fabric using the same will be described.
