Description

Technical Field

[0002] The raw material of cotton sweaters is natural cotton, which is deeply loved by consumers because of its soft feel and comfortable wearing. However, because cotton fibers themselves have super water absorption, they swell after absorbing water, causing the cotton fiber yarn to shorten and deform, and the cotton fabric loses its original elasticity and support; the fiber structure of cotton fibers is combined with water molecules. Due to the existence of hydrogen bonds between water molecules, in the process of drying clothes, the hydrogen bonds are broken, and the distance between fiber molecules is reduced, which will cause the clothes to become wrinkled. Therefore, it is inevitable that pure cotton clothes that have been worn for a long time will deform and become loose. Utility Model Content

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Combination Figure 1 The present embodiment is described in detail. A deformation-resistant cotton sweater comprises a sweater main body 1, wherein the sweater main body 1 comprises a body portion 2 and a sleeve portion 3, wherein the body portion 2 and the sleeve portion 3 are connected by sewing; the body portion 2 and the sleeve portion 3 are both anti-deformation fabrics 4; the anti-deformation fabric 4 comprises a first fabric layer 5, a second fabric layer 6 and a third fabric layer 7 which are compounded in sequence; the first fabric layer 5, the second fabric layer 6 and the third fabric layer 7 are compounded by dot-shaped hot melt adhesive; the second fabric layer 6 is knitted by a second composite yarn, and the second composite yarn is a cotton-spandex core-spun yarn.

[0015] Specifically, the cotton-spandex core-spun yarn is made of spandex filaments as the core and a layer of uniform cotton fibers wrapped on the outside, which can not only give full play to the high elasticity of spandex, but also maintain the advantages of cotton fibers. The fabric is comfortable, fits well, and is soft and breathable.

[0016] Furthermore, the first fabric layer 5 is knitted from a first composite yarn, wherein the first composite yarn is twisted from polylactic acid fiber filaments and polyester hot-melt yarns, and the cross-section of the polylactic acid fiber filaments is Y-shaped.

[0017] Polylactic acid fiber is a synthetic polymer material made from corn, soybean and other grains through fermentation, polymerization and spinning. It has excellent biocompatibility and biodegradability. Starch is initially extracted from corn, soybean and other grains, and the starch is decomposed and refined into plant sugar by enzymes. Lactic acid is formed after lactic acid bacteria fermentation, and high-purity polylactic acid is obtained through chemical synthesis. Finally, it is processed into polylactic acid fiber through spinning process. The strength of polylactic acid fiber is slightly lower than that of polyester and nylon fiber, but the elongation at break is larger, and its modulus is also lower, which is only half of that of polyester fiber. Therefore, polylactic acid fiber textiles are much softer than polyester products. In addition, polylactic acid fiber has excellent elastic recovery, especially under large deformation conditions (deformation greater than 10%), its elastic recovery rate is not only better than wool and acrylic fiber, but even higher than nylon fiber. Polylactic acid fiber also has certain antibacterial properties, which is because polylactic acid contains trace amounts of lactic acid or oligomers with antibacterial effects. A part of it leached on the fiber surface will maintain the same weak acidity as human skin, thereby preventing the attachment and reproduction of microorganisms such as bacteria and molds. In addition, polylactic acid fiber is a lactic acid polymer synthesized from lactic acid contained in the human body. Lactic acid can be decomposed and absorbed by the human body, so polylactic acid fiber has good compatibility with human skin and will not irritate the skin. The fiber porosity of the Y-shaped cross-section is 40%, which is more than double the porosity of the circular cross-section. These pores provide capillary channels for sweat moisture diversion, which is conducive to moisture absorption and perspiration.

[0018] Furthermore, the third fabric layer 7 is knitted from a third composite yarn, and the third composite yarn is twisted from tea fiber yarn and polyester hot melt yarn.

[0019] Tea contains a large number of phenolic hydroxyl compounds, such as polyphenol compounds, which can achieve good antibacterial and deodorizing functions through the principle of reduction decomposition and the additional combination of -NH2, -SH and other odor components. Antibacterial agents such as tea polyphenols and tea pigments in tea are added to the viscose spinning solution in the form of fine particles or solutions, and tea fibers can be made using conventional wet spinning and spinning processes. Because the antibacterial agents are evenly distributed inside the fiber, they continue to be antibacterial and deodorizing. As a functional fiber, tea fiber is made of natural and environmentally friendly raw materials, and is naturally beige in color and does not require dyeing. Tea fiber has good moisture absorption and air permeability, has antibacterial and health functions, and has good elasticity and is not easy to deform.

[0020] The hot melt is also called fusible yarn or fusible bonding yarn. The melting point can be controlled at 110°C by adjusting the properties of the raw materials. At room temperature, the hot melt is woven into a fabric with other fibers, and then an array of point pressure is applied to the fabric under dry heat or wet heat. When the temperature is higher than the melting point of the hot melt, the hot melt gradually melts. At this temperature, the other fibers remain unchanged and are bonded together by the hot melt to form bonding points to prevent the fibers from falling apart. Compared with ordinary fibers, it melts at a relatively low temperature and gives the desired adhesion without damaging the fibers and fabrics, so that the fabric is stable in shape and not easily deformed. In this embodiment, the above-mentioned treatment is performed on the first fabric layer, the second fabric layer and the third fabric layer after compounding, so that the connection between the layers can be tighter, so that the overall shape of the anti-deformation fabric is more stable and not easily deformed.

[0021] Furthermore, the body portion 2 is provided with a hem 8, and the sleeve portion 3 is provided with cuffs 9; the hem 8 and the cuffs 9 are both ribbed.

[0022] Furthermore, the hem 8 and cuffs 9 are woven from elastic yarn, and the elastic yarn is polyester-spandex coated yarn. The polyester-spandex coated yarn has spandex as the core and polyester filament as the outer coating. This yarn has good elasticity and strength, and the hem and cuffs woven into it have good elastic recovery and are not easy to deform.

[0023] 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.
