Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, specifically to a double-layer satin fabric made of Apocynum venetum. Background Technology

[0002] Apocynum venetum, a natural functional fiber plant, is a wild fiber plant unique to China. Its fibers combine natural functionality with environmental friendliness. Apocynum venetum fiber contains flavonoids, fatty acids, and volatile oils, among other antibacterial components, exhibiting significant inhibitory effects against Staphylococcus aureus, Escherichia coli, and Candida albicans, demonstrating natural antibacterial properties. Apocynum venetum fiber also possesses excellent moisture absorption and breathability. Its fiber structure contains numerous cracks and pores, allowing for rapid absorption and evaporation of sweat, keeping the wearer dry. Furthermore, the complex cross-sectional structure of Apocynum venetum fiber effectively blocks ultraviolet rays, providing strong UV shielding capabilities, making it suitable for summer clothing.

[0003] However, its industrial application has long been limited by the following inherent defects: 1. Poor mechanical properties: The fiber has high stiffness and low elongation at break, resulting in a rough and stiff feel to pure spun fabrics, and insufficient abrasion resistance; 2. High processing difficulty: The fiber surface is smooth and the length dispersion is large, making it easy to break during spinning, and the yarn strength is only 60% of that of cotton fiber; 3. Conflict between function and comfort: Although a high proportion of blending can improve performance (such as adding polyester to improve abrasion resistance), it will weaken its core advantages of natural antibacterial and breathability. At present, although chemical softener treatment or single blending can partially alleviate the above problems, it is difficult to meet the dual requirements of abrasion resistance enhancement and hand softening.

[0012] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in the following embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments: A double-layer satin fabric made of Apocynum venetum includes a face fabric and a lining fabric. The face fabric is woven from face warp and face weft, and the lining fabric is woven from lining warp and lining weft. The face fabric and lining fabric are joined by a weft-jointing method, specifically a weft-jointing method. The face fabric uses a 3 / 8 warp-density satin weave, and both the lining fabric and the weft-jointing fabric use a 3 / 8 weft-density satin weave. The warp and weft yarn ratio of both the face fabric and the lining fabric is 1:1. The complete structure of the double-layer satin fabric consists of 8 face fabric warp yarns. The structure is composed of 8 outer weft yarns, 8 inner weft yarns, and 8 inner weft yarns interwoven. The first warp weft point is where the outer weft yarns float above the weft yarns; the second warp weft point is where the inner weft yarns float above the weft yarns; the third warp weft point is where the inner weft yarns are above the outer weft yarns; and the fourth warp weft point is where the outer weft yarns are above the inner weft yarns. Through the layered design of the outer weft (3 / 8 warp-dense satin) and the inner weft (3 / 8 weft-faced satin), combined with the inner warp joining method of the weft-faced structure, functional zoning is achieved. The outer fabric is a warp-faced satin weave with a high coverage of warp floats, giving it a smooth surface and abrasion resistance. The inner fabric is a weft-faced satin weave with predominantly weft floats, enhancing its softness and skin-friendly feel. Both the outer and inner fabrics of the complete weave use a cycle of 8 warp yarns × 8 weft yarns, combined with a 1:1 warp-to-weft yarn ratio, resulting in a uniform fabric structure with moderate density. The first warp weft point of the first column of the complete weft structure is above the weft yarns of the second, third, fourth, fifth, sixth, seventh, and eighth rows; The first warp weft point is located above the weft yarns in rows 1, 2, 3, 5, 6, 7, and 8 of the fully structured second column. The warp yarn in the third column of the complete structure is the first warp weft point above the weft yarns in rows 1, 2, 3, 4, 5, 6, and 8; The first warp weft point is located above the weft yarns in rows 1, 3, 4, 5, 6, 7, and 8 of the fully structured warp yarns. The first warp weft point is located above the weft yarns in rows 1, 2, 3, 4, 6, 7, and 8 of the fully structured warp yarn. The warp yarn in the 6th column of the complete structure is the first warp weft point above the weft yarns in rows 1, 2, 3, 4, 5, 6, and 7; The warp yarn in the 7th column of the complete structure is the first warp weft point above the weft yarns in rows 1, 2, 4, 5, 6, 7, and 8; The warp yarn in the 8th column of the complete structure is the first warp weft point above the weft yarns in rows 1, 2, 3, 4, 5, 7, and 8; The warp yarn in the first column of the complete weave structure is the second warp weave point above the weft yarn in the sixth row; The warp yarns of the second column of the complete weave are above the weft yarns of the first row, forming the second warp weave point; The warp yarn in the third column of the complete weave structure is the second warp weave point above the weft yarn in the fourth row; The warp yarn in column IV of the complete weave structure is the second warp weave point above the weft yarn in row VII; The warp yarn in column V of the complete weave structure is the second warp weave point above the weft yarn in row II; The warp yarn in column VI of the complete weave structure is the second warp weave point above the weft yarn in row V; The warp yarn in column VII of the complete weave structure is the second warp weave point above the weft yarn in row VIII; The warp yarn in column VIII of the complete weave structure is the second warp weave point above the weft yarn in row III; The warp yarn in the first column of the complete weave is the third warp weave point above the weft yarn in the sixth row; The warp yarns of the second column of the complete weave are at the third warp weave point above the weft yarns of the first row; The warp yarn in the third column of the complete weave is the third warp weave point above the weft yarn in the fourth row; The warp yarn in column IV of the complete weave structure is the third warp weave point above the weft yarn in row 7; The warp yarn in column V of the complete weave is the third warp weave point above the weft yarn in row 2; The warp yarn in column VI of the complete weave is the third warp weave point above the weft yarn in row 5. The warp yarn in column VII of the complete weave is the third warp weave point above the weft yarn in row 8; The warp yarn in column VIII of the complete weave is the third warp weave point above the weft yarn in row 3; The warp yarns of columns 1, 2, 3, 4, 5, 6, 7, and 8 of the complete weave are the fourth warp weave point above the weft yarns of rows I, II, III, IV, V, VI, VII, and VIII.

[0013] Preferably, both the outer and inner warp are 18 tex × 2 strands of Apocynum venetum and polyester blended yarn, with a blending ratio of 70 / 30. The high strength and wrinkle resistance of polyester compensate for the shortcomings of short fibers and poor cohesion of Apocynum venetum, while retaining the antibacterial properties and far-infrared emission function of Apocynum venetum. The double-strand structure can improve the yarn strength and abrasion resistance, and reduce the weaving breakage rate. The outer weft is 20 tex strands of Apocynum venetum and polyester blended yarn, with a blending ratio of 70 / 30. The inner weft is 18 tex strands of Apocynum venetum and viscose blended yarn, with a blending ratio of 50 / 50. The blending of viscose and Apocynum venetum, due to the high moisture absorption of viscose, improves the breathability and sweat-wicking ability of the inner layer, making it suitable for wearing next to the skin.

[0014] Preferably, the twist of the outer and inner warp is 300~380 twists / meter. The high twist increases the cohesion between the Apocynum venetum fiber and the polyester fiber, while compensating for the surface smoothness defect of the Apocynum venetum fiber. The twist direction is Z twist.

[0015] Preferably, the twist of the outer weft and inner weft is 250~280 twists / meter. The lower weft twist (compared to the warp) can reduce yarn rigidity and avoid internal stress imbalance caused by excessive weft shrinkage of the fabric. The twist direction is S twist, and the Z twist warp and S twist weft are configured in opposite directions to offset the internal stress of weaving.

[0016] Preferably, the finished warp density of the Apocynum venetum double-layer satin fabric is 360-400 threads / 10cm, and the finished weft density is 240-260 threads / 10cm. The high warp density design enhances the mechanical properties of the fabric by increasing the warp yarn coverage, while the moderate weft density balances the breathability and weft tightness of the fabric.

[0017] This invention employs a double-layer satin structure, with a warp-faced satin outer layer and a weft-faced satin inner layer. The long floats in the warp-faced satin reduce direct friction between the yarn and the external environment, minimizing fiber wear. Simultaneously, the long floats impart a soft and smooth feel to the fabric. Furthermore, the satin structure has fewer interlacing points, resulting in less yarn bending and reduced fiber breakage. Regarding yarn selection, Apocynum venetum fiber itself suffers from significant length variations, a smooth, non-curled surface, and low cohesion, leading to easy scattering during spinning and a low yield. By blending it with polyester and viscose fibers, the spinnability of Apocynum venetum fiber is effectively improved, enhancing yarn uniformity and stability, and ultimately improving performance.

[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
