Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a high-density polyester weft-elastic fabric. Background Art

[0002] Fabric density refers to the number of warp yarns and weft yarns per unit length under wrinkle-free and tension-free conditions, generally expressed as yarns / 10cm, and is an important indicator of textile fabrics. Fabric density has a great influence on the appearance, quality, feel, strength, thickness, wrinkle resistance, elasticity, wear resistance, water permeability, and warmth retention of the fabric. According to the actual production and use of chemical fiber filament fabrics, fabrics with a warp density plus weft density of 1200 yarns / 10cm or above are usually identified as high-density fabrics. With the improvement of people's living standards and the continuous development of the textile industry, the fabrics used for some clothing such as suits, windbreakers, and down jackets are becoming more and more sophisticated. High-density fabrics are widely used in clothing, such as the lining of suits and windbreakers, the lining of down jackets, and the lining of skirts.

[0003] When high-density fabrics are used as lining materials for suits or windbreakers, they usually have the advantages of being comfortable to wear, sweat-wicking and breathable, and having a crisp drape. However, the existing high-density fabrics are slightly insufficient in elasticity. When used as lining materials for suits or windbreakers, they usually also need to have elasticity along the weft direction to adapt to the wearer's activities and facilitate the stretching of limbs. Therefore, it is necessary to develop a high-density polyester weft-elastic fabric. Utility Model Content

[0011] Figure 1 It is the five three-fly satin weave pattern involved in the utility model;

[0012] In the figure: 1-first warp yarn, 2-second warp yarn, 3-third warp yarn, 4-fourth warp yarn, 5-fifth warp yarn. DETAILED DESCRIPTION

[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 high-density polyester weft elastic fabric comprises: a fabric body, the fabric body is interwoven with warp yarns and weft yarns; the fabric body is a five-piece three-fly satin weave; the warp density of the fabric body is 1500-1600 strands / 10cm, and the weft density is 1100-1300 strands / 10cm; the warp yarns include a first warp yarn 1, a second warp yarn 2, a third warp yarn 3, a fourth warp yarn 4, and a fifth warp yarn 5; the first warp yarn 1 and the second warp yarn 2 are acetate cellulose filaments; the third warp yarn 3, the fourth warp yarn 4, and the fifth warp yarn 5 are twisted with polyester fiber filaments and mint fiber yarns; the weft yarn is an elastic yarn. Specifically, in the present embodiment, the warp density of the fabric body is 1580 strands / 10cm, and the weft density is 1220 strands / 10cm.

[0015] Cellulose acetate filaments are made from wood pulp. After acetylation, 74%-92% of the hydroxyl groups in cellulose react with acetic anhydride to form cellulose acetate ester, which is then dry-spun. Cellulose acetate filaments are breathable, comfortable to the touch, soft in luster, and not prone to static electricity. They have long been widely used in the lining of suits or windbreakers.

[0016] Mint fiber uses natural mint as raw material, combines nano-crushing technology and microcapsule technology, and blends the effective ingredients of mint with cellulose in the form of microcapsules for spinning into fibers. Mint fiber has natural antibacterial function, and has good antibacterial properties against Staphylococcus aureus, Escherichia coli, and Candida albicans, with an antibacterial rate of 99%; the natural mint ingredients give the fiber a natural cool feeling, giving the human body a comfortable wearing experience; the fabric has the advantages of softness, comfort, and good breathability.

[0017] Furthermore, the cross section of the polyester fiber filament is cross-shaped or Y-shaped. Specifically, in this embodiment, the cross section of the polyester fiber filament is Y-shaped. The porosity of the Y-shaped cross-section fiber is 40%, and these pores provide capillary channels for sweat moisture conduction, which has excellent moisture conduction and perspiration function, and the fabric of the Y-shaped cross-section fiber has fewer contact points with the skin, which can reduce the sticky feeling when sweating and improve the comfort of the wearer.

[0018] Furthermore, the elastic yarn is a polyetherester elastic yarn. Specifically, the polyetherester elastic yarn is made by spinning elastic short fibers of a blend of polyetherester and polybutylene terephthalate using a traditional ring spinning process. When the elongation of this yarn is 40%, the elastic recovery rate is greater than 95%. While maintaining the characteristics of a high elastic recovery rate, it can achieve high strength of 2cN / dtex and low elongation of 50%; at a fixed elongation of 15%, the elastic recovery rate is greater than 95%. At the same time, the elastic recovery rate of the elastic yarn can still reach 90% after 6 repeated cycles of 20%.

[0019] Furthermore, the surface density of the fabric body is 100-110g / ㎡. In this embodiment, the surface density of the fabric body is 102g / ㎡. The fabric is soft and thin as a whole, and the number of interlacing points of the satin weave is small, the floating lines are longer and densely distributed, and the fabric has more pores. Therefore, the air permeability, thermal conductivity, wicking, and moisture permeability are better than those of plain and twill weaves.

[0020] Embodiment 2

[0021] Furthermore, the elastic yarn is a spandex core-spun yarn, which has spandex filaments as the core and milk protein composite fibers wrapped on the outside. The milk protein composite fiber is a regenerated fiber that is different from natural fibers and synthetic fibers, which is formed by extracting protein molecules from milk, reacting and grafting with the macromolecular compound polyacrylonitrile, and finally spinning by wet spinning. It has the advantages of both natural fibers and synthetic fibers and has good biodegradability. The surface of the milk protein composite fiber is creamy, giving the fiber a silky smooth feel and luster; the milk protein composite fiber is dehydrated on the fiber surface during the spinning process, leaving countless irregular grooves and uneven small holes in the longitudinal direction of the fiber, and many tiny pores will appear on the cross section, which makes the fiber have good moisture absorption and air permeability. Therefore, the spandex core-spun yarn not only has the good elasticity of spandex, but also has the advantages of good softness, moisture conduction, and air permeability.

[0022] 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.
