Wool / silk fiber siro spinning blended yarn

Abstract

The utility model discloses wool / silk fiber siro spinning blended yarn which comprises core yarn, mercerized wool fiber yarn and silk fiber yarn, wherein the mercerized wool fiber yarn and the silk fiber yarn are spirally wound on the outer side of the core yarn in a siro spinning mode. Fibers used by the core yarns are non-permanent shaped stretched wool fibers. According to the wool / silk fiber siro spinning blended yarn, the core yarn uses the non-permanent shaped stretched wool, and when a fabric woven by the non-permanent shaped stretched wool is subjected to post-treatment, the core yarn shrinks, so that the fineness of the blended yarn is improved, and the compactness of the fabric is improved.

Description

Technical Field

[0001] The utility model relates to a wool / silk fiber siro-spun blended yarn, belonging to the technical field of siro-spun core-spun yarns. Background Art

[0002] Siro spinning core-spun yarn is also called Sirofil spinning. This spinning method is a spinning method developed on the basis of Siro spinning. A yarn feeding device is added to the Siro spinning machine modified from an ordinary ring spinning machine. The added yarn is directly fed by the front roller and output at a certain distance from the two drafted whiskers at the outlet of the front roller. The two whiskers are twisted separately and converged at a certain point, and then the strands are twisted as a whole to form the core-spun yarn. The production process omits the process of doubling and twisting, shortens the process flow, and reduces production costs.

[0003] In the weaving process of conventional fabrics, the warp yarn needs to pass through the steel reed, and gaps will be formed on the fabric at the position of the reed teeth, making the fabric sparse. If the fabric is dense, the density of the yarn needs to be increased, but increasing the density of the warp yarn will make the weaving process difficult.

[0004] Silk and wool fibers are both natural protein fibers and are commonly used fibers for making high-end fabrics. How to prepare a wool / silk fiber Siro-spun yarn that can improve the density of fabrics when weaving fabrics has become a problem to be solved. Utility Model Content

[0005] The utility model aims to provide a wool / silk fiber siro-spun blended yarn, wherein the non-permanently shaped stretched wool fiber used shrinks during post-treatment, thereby improving the density of the fabric.

[0006] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0007] The utility model relates to a wool / silk fiber siro-spun blended yarn, comprising a core yarn, and mercerized wool fiber yarn and silk fiber yarn spirally wound around the outer side of the core yarn by a siro-spinning method; the fiber used in the core yarn is a non-permanently shaped stretched wool fiber.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the silk fiber used in the silk fiber yarn is tussah silk fiber.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: there is a set distance between the mercerized wool fiber yarn and the silk fiber yarn.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the outer side of the core yarn also includes antibacterial cotton fiber yarn, and the antibacterial cotton fiber yarn is arranged parallel to the silk fiber yarn.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the antibacterial cotton fiber yarn is located between the mercerized wool fiber yarn and the silk fiber yarn, and has a set distance between them.

[0012] The beneficial effect of the utility model is that the wool / silk fiber siro-spun blended yarn involved in the utility model uses non-permanently set stretched wool as the core yarn, and when the fabric woven therefrom is post-processed, the core yarn shrinks, thereby improving the fineness of the blended yarn and thus improving the density of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 1 is a schematic diagram of the structure of the wool / silk fiber siro-spun blended yarn involved in Example 1;

[0014] Figure 2 It is a schematic diagram of the structure of the wool / silk fiber siro-spun blended yarn involved in the second embodiment.

[0015] The markings in the figure are as follows: 1-core yarn; 2-mercerized wool fiber yarn; 3-silk fiber yarn; 4-antibacterial cotton fiber yarn. DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] Combination Figure 1 , this embodiment is described in detail. The wool / silk fiber siro-spun blended yarn involved in this embodiment comprises a core yarn 1, and mercerized wool fiber yarn 2 and silk fiber yarn 3 spirally wound around the outer side of the core yarn 1 by siro-spinning; the fiber used in the core yarn 1 is non-permanently set stretched wool fiber.

[0019] Stretched and thinned wool is a fiber with a very special shape. After being stretched and thinned, the fineness and length of the wool are changed. In the subsequent shaping process, through the innovative shaping process, the shape of the stretched and thinned wool can be permanently fixed, or the shape of the stretched and thinned wool can be temporarily fixed, that is, non-permanently shaped, and deformed when it encounters high temperature and humidity in the future. This non-permanently shaped stretched and thinned wool is very useful. When producing dense and thick worsted wool fabrics, velvet products with hairiness, and full and elastic wool fabrics, non-permanently shaped stretched and thinned wool is one of the best high-grade raw materials. The stretched wool used in this embodiment is non-permanently shaped, which can shrink during the subsequent processing of the fabric, thereby improving the density of the woven fabric.

[0020] Furthermore, the silk fiber used in the silk fiber yarn 3 is tussah silk fiber. Tussah silk with a porous structure is composed of many fine fibers that are neatly and tightly arranged. Its fibroin protein content is 15% higher than that of ordinary mulberry silk, and its density is smaller than that of other textile fibers. Its strength and elongation are similar to those of wool fibers, higher than those of down and better than those of mulberry silk. Since the acid resistance of tussah silk is more than 3 times that of mulberry silk, its alkali resistance and chemical corrosion resistance are stronger. The fineness of tussah silk is twice that of mulberry silk, and its ability to absorb ultraviolet rays is 3.5 times that of mulberry silk. The raw material performance is better than that of mulberry silk, and it feels soft and fluffy; the unique fiber structure of tussah silk gives it advantages in terms of hygroscopicity, breathability, warmth retention, and fluffiness.

[0021] Mercerized wool refers to wool that has been first treated with oxidation or protease to destroy and remove the scales on the surface of the wool, reducing the difference in the friction coefficient of the wool during forward and reverse movement. The treated wool fibers have good luster and feel.

[0022] Furthermore, there is a set distance between the mercerized wool fiber yarn 2 and the silk fiber yarn 3. The set distance is half of the diameter of the silk fiber yarn 3.

[0023] Embodiment 2

[0024] Combination Figure 2 , this embodiment is described in detail. The wool / silk fiber siro-spun blended yarn involved in this embodiment is different from that in the first embodiment in that the outer side of the core yarn 1 also includes an antibacterial cotton fiber yarn 4, and the antibacterial cotton fiber yarn 4 is arranged in parallel with the silk fiber yarn 3. The antibacterial cotton fiber yarn 4 uses copper ion modified antibacterial cotton fiber, which has a good antibacterial effect while maintaining good hygroscopicity.

[0025] Furthermore, the antibacterial cotton fiber yarn 4 is located between the mercerized wool fiber yarn 2 and the silk fiber yarn 3, and has a set spacing between them. The spacing is the same as in the first embodiment, which is half of the diameter of the silk fiber yarn 3.

[0026] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
