BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a schematic structural diagram of the elastic suede-like fabric involved in the present utility model;
[0011] In the figure: 1-first fabric layer, 2-second fabric layer. DETAILED DESCRIPTION
[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0013] Example 1
[0014] Combine Figure 1 This embodiment is described in detail. A stretch suede-like fabric comprises: a first fabric layer 1 and a second fabric layer 2; the first fabric layer 1 and the second fabric layer 2 are connected by sewing; the first fabric layer 1 is formed by warp knitting a first stretch core-spun yarn; the first stretch core-spun yarn comprises a core yarn and a first wrapping yarn, the core yarn is spandex filament, and the first wrapping yarn is polyester sea-island yarn; the second fabric layer 2 is formed by warp knitting a second stretch core-spun yarn; the second stretch core-spun yarn comprises a core yarn and a second wrapping yarn, the core yarn is spandex filament, and the second wrapping yarn comprises mercerized wool Sorona fiber nylon semi-worsted yarn.
[0015] Furthermore, the spandex filament has a fineness of 40D. Spandex fiber is a segmented copolymer. One segment, called the hard segment, is crystalline due to the presence of polar groups and exhibits little deformation under stress, while maintaining elastic recovery. The other segment, called the soft segment, is composed of a non-crystalline, relatively low molecular weight polyester or polyether with an average molecular weight of 1000-5000. It has a very low glass transition temperature and is in a highly elastic state at room temperature. It easily deforms under stress, thus endowing the fiber with the characteristic of being easily elongated. The first and second elastic core-spun yarns have spandex as the core yarn, ensuring excellent elasticity, and are wrapped with non-elastic yarn on the outside, ensuring good feel, appearance, and comfort. The spandex is pre-stretched before wrapping, resulting in shrinkage significantly different from that of the wrapped non-elastic yarn. After the wrapped spandex shrinks, the non-elastic yarn is compressed axially, exhibiting properties similar to bulked yarn, resulting in an elastic core-spun yarn. The first elastic core-spun yarn and the second elastic core-spun yarn are both elastic spandex core-spun yarns, which can impart elasticity to the fabric.
[0016] Furthermore, the polyester island-in-the-sea yarn has specifications of 16.7tex / 36f / 37i. Specifically, the island-in-the-sea POY multifilament yarn features semi-matt PET as the island phase and COPET as the sea phase, with a sea / island ratio (wt%) of 25 / 75, and a total of 37 islands per single fiber. After the fabric is opened, the sea phase dissolves, resulting in a powdery, soft feel and a suede-like appearance, achieving the desired suede-like surface morphology and feel required of suede-like fabrics.
[0017] Sea island silk is widely used in the production of simulated leather fabrics for various types of clothing, shoes, bags, and simulated leather base fabrics for PU leather. The suede-like fabric produced with it as raw material has a simulation effect that not only meets the requirements for the appearance of the leather, such as shape and color, but also meets the requirements for comfort such as warmth, breathability, and moisture permeability. It surpasses natural leather in terms of easy-to-care properties such as washability, mildew resistance, and moth resistance. Therefore, it is deeply loved by those who pursue fashion and leisure.
[0018] Furthermore, the fineness of the mercerized wool Sorona fiber nylon semi-worsted yarn is 54Nm. Specifically, the mercerized wool Sorona fiber nylon semi-worsted yarn is blended from 50% mercerized wool, 30% Sorona fiber, and 20% nylon fiber.
[0019] Mercerized wool is a product created by partially or completely removing the scales from the wool surface through physical or chemical methods. Mercerized wool fibers exhibit excellent elongation and elastic recovery, a silky sheen, and fabrics made from them are stretchy, soft, shrink-resistant, and machine-washable. However, mercerized wool experiences a fiber strength reduction of approximately 10%. Sorona fiber is a bio-based polymer fiber primarily derived from crops such as corn. Bio-based and renewable, Sorona fiber blends garments with vibrant colors, excellent stretchability, a naturally soft feel, and wrinkle-free properties. Due to Sorona fiber's low strength, the removal of the scales from mercerized wool significantly weakens the fiber. Adding nylon fiber, which boasts the highest abrasion resistance among textile fibers, high breaking strength, good elongation, and excellent fatigue resistance, can compensate for the shortcomings of the other two fibers, improving the yarn's wear resistance and strength. The mercerized wool Sorona fiber nylon semi-worsted yarn has a cashmere-like feel, a mulberry silk-like luster, excellent extensibility and easy care.
[0020] Example 2
[0021] On the basis of Example 1, the second wrapped yarn also includes a milk protein composite fiber wool blended yarn, and the mercerized wool Sorona fiber nylon semi-worsted yarn and the milk protein composite fiber wool blended yarn are twisted together. Specifically, the blending ratio of the milk protein composite fiber wool blended yarn is milk protein composite fiber 15 / wool 85. Milk protein composite fiber is a fiber artificially synthesized using milk protein and macromolecular organic compounds as raw materials and new biological and chemical textile technologies. Milk protein composite fiber is green and environmentally friendly, contains more than ten kinds of amino acids and natural moisturizing factors that are beneficial to the human body, can protect the skin, has a natural luster like silk, a soft feel like cashmere, a luxurious appearance, a pleasant luster, and also has good moisture absorption and moisture conduction properties and spectral antibacterial properties. Combining the characteristics of milk protein composite fiber with the good elasticity and warmth retention of wool can overcome the itchy feeling of wearing pure wool close to the skin.
[0022] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
