Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, and in particular to a factory-produced raw silk crepe fabric. Background Technology
[0002] Crepe yarn is a medium-twist yarn, which is made by combining a medium-twist coarse yarn and a weakly twisted fine yarn, and then adding a twist in the opposite direction to the coarse yarn. The weakly twisted fine yarn forms a medium and strong twist, which produces a twist shrinkage, while the medium-twist coarse yarn is twisted in the opposite direction, which reduces the original twist. With one shrinkage and one loosening, the fine yarn shrinks and naturally lies in the center of the yarn, while the coarse yarn loosens and naturally surrounds the fine yarn, forming a soft, fluffy and elastic linear structure. The surface of the fabric made from this yarn has a subtle water ripple appearance.
[0003] The existing crepe yarn products are primarily made from raw silk from silkworms fed with mulberry leaves. The warp yarn is low-twist crepe yarn from these silkworms, while the weft yarn is also made from crepe yarn from the same silkworms. However, feeding silkworms with fresh mulberry leaves is highly dependent on the season and climate, making quality stability difficult to control and resulting in high costs. Alternatively, the warp yarn can be fine-count, and the weft yarn can be short-fiber crepe yarn. If the twist direction and twist ratio are not properly matched in the spinning design, problems such as twist shrinkage, insufficient stress release, and weak surface texture in the finished product can occur, resulting in a loss of the product's distinctive style.
[0004] Factory silkworm rearing is a modern method that places traditional silkworm rearing in a fully enclosed, temperature- and humidity-controlled environment. Silkworms complete their growth cycle by being fed artificial feed, eliminating reliance on fresh mulberry leaves and completely freeing them from seasonal and climatic dependence. It boasts advantages such as high efficiency, pollution resistance, high standardization, intensification, and intelligent operation. This solves the problem of resource depletion, reduces cocoon costs, and improves the cost-effectiveness of raw silk fibers. However, for the same grade of silk thread, factory-raised raw silk has a slightly higher breaking elongation than silk from mulberry-leaf-fed silkworms, while its crystallinity and breaking strength are slightly lower. This leads to increased thread breakage during weaving, severely impacting weaving efficiency. Consequently, factory-raised raw silk is currently mainly used in the production of products such as silk quilts, resulting in low added value.
[0005] Therefore, developing a factory-raised silk crepe fabric can fully leverage the advantages of both factory-raised silk and mulberry leaf-fed silk, broaden the application areas of factory-raised silk, and reduce the production cost of silk crepe, thus having significant application value. Summary of the Invention
[0006] The purpose of this invention is to solve the problems in the existing technology and propose a factory-raised silk crepe fabric that can give full play to the advantages of both factory-raised silk and mulberry leaf-fed silk, broaden the application field of factory-raised silk, and reduce the production cost of silk crepe, thus having great application value.
[0007] To achieve the above objectives, this utility model proposes a factory-raised silk crepe fabric, comprising warp yarns and weft yarns. The warp yarns consist of several strands of factory-raised silk and / or several strands of mulberry leaf-fed silk. The weft yarns are crepe yarns formed by combining, twisting, and shaping coarse and fine filaments. The coarse and fine filaments have different fineness, different twists, and opposite twisting directions. The coarse yarns consist of several strands of factory-raised silk and / or several strands of mulberry leaf-fed silk, and the fine yarns consist of several strands of factory-raised silk and / or several strands of mulberry leaf-fed silk.
[0008] Preferably, the warp yarn is formed by combining, twisting, and shaping several strands of raw silk from factory-raised silkworms and several strands of raw silk from silkworms fed with mulberry leaves.
[0009] Preferably, the ratio of raw silk from factory-raised silkworms to raw silk from silkworms fed with mulberry leaves is 1:4, 2:3, 3:2, 4:1, or 5:0, and the added twist is less than 10 twists / cm.
[0010] Preferably, the filament is formed by combining, twisting, and shaping several strands of raw silk from factory-raised silkworms and several strands of raw silk from silkworms fed with mulberry leaves.
[0011] Preferably, the ratio of raw silk from factory-raised silkworms to raw silk from silkworms fed with mulberry leaves is 1:2, 2:1, or 3:0, and the added twist is less than 10 twists / cm.
[0012] Preferably, the coarse silk is formed by combining, twisting, and shaping several strands of raw silk from factory-raised silkworms and several strands of raw silk from silkworms fed with mulberry leaves.
[0013] Preferably, the ratio of raw silk from factory-raised silkworms to raw silk from silkworms fed with mulberry leaves is 1:5, 2:4, 3:3, 4:2, 5:1, or 6:0, and the added twist is 10-20 twists / cm.
[0014] The beneficial effects of this utility model are as follows: By using raw silk from factory-raised silkworms as the warp yarn of the fabric, the production cost of crepe de chine fabric is effectively reduced, and the application field of factory-raised silkworm raw silk is significantly broadened. By using crepe de chine yarn containing factory-raised silkworm raw silk as the weft yarn of the fabric, on the one hand, the breaking strength is improved as the core yarn, and the high breaking elongation of factory-raised silkworm raw silk is effectively utilized; on the other hand, as the weft yarn, the resulting factory-raised silkworm raw silk crepe de chine has a soft and elastic feel, and can also take advantage of the good abrasion resistance of mulberry leaf-fed silkworm raw silk. The woven fabric has a water-wave crepe texture on the surface. Compared with the prior art, it can give full play to the advantages of both factory-raised silkworm raw silk and mulberry leaf-fed silkworm raw silk, broaden the application field of factory-raised silkworm raw silk, and reduce the production cost of raw silk crepe de chine, which has great application value.
[0015] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
[0016] Figure 1 This is a structural schematic diagram of a factory-produced raw silk crepe fabric based on the present invention.
[0017] Figure 2 This is a schematic diagram of the weft yarn structure.
[0018] In the diagram: 1-warp yarn, 2-weft yarn, 21-coarse yarn, 22-fine yarn. Detailed Implementation
[0019] See Figure 1 , Figure 2 This utility model discloses a factory-raised silk crepe fabric, comprising warp yarns 1 and weft yarns 2. The warp yarns 1 comprise several factory-raised silk filaments and / or several silk filaments fed with mulberry leaves. The weft yarns 2 are crepe yarns formed by combining, twisting, and shaping coarse filaments 21 and fine filaments 22. The coarse filaments 21 and fine filaments 22 have different fineness, different twists, and opposite twisting directions. The coarse filaments 21 comprise several factory-raised silk filaments and / or several silk filaments fed with mulberry leaves, and the fine filaments 22 comprise several factory-raised silk filaments and / or several silk filaments fed with mulberry leaves.
[0020] The warp filament 1 is formed by combining, twisting and shaping several raw silks from factory-raised silkworms and several raw silks from mulberry leaves fed to silkworms. The ratio of the combined raw silks from factory-raised silkworms to the raw silks from mulberry leaves (the number of combined raw silks is 5) is 1:4, 2:3, 3:2, 4:1 or 5:0, and the twist is less than 10 twists / cm.
[0021] The fine filament 22 is formed by combining, twisting and shaping several raw silks from factory-raised silkworms and several raw silks from mulberry leaves fed to silkworms. The ratio of the combined raw silks from factory-raised silkworms to the raw silks from mulberry leaves (the number of combined raw silks is 3) is 1:2, 2:1 or 3:0, and the twist is less than 10 twists / cm.
[0022] The coarse filament 21 is formed by combining, twisting and shaping several raw silks from factory-raised silkworms and several raw silks from mulberry leaves fed to silkworms. The ratio of the combined raw silks from factory-raised silkworms to the raw silks from mulberry leaves (the number of combined raw silks is 6) is 1:5, 2:4, 3:3, 4:2, 5:1 or 6:0, and the twist is 10 to 20 twists / cm.
[0023] The coarse filament 21 and fine filament 22 are combined, and the twist is between 8 and 16 twists / cm. The twist direction is the same as the twist direction of the fine filament 22 and opposite to the twist direction of the coarse filament 21. After the twist is added, the yarn loosens and naturally wraps around the core yarn, making the resulting factory-raised silk crepe yarn soft and elastic to the touch. It also takes advantage of the good abrasion resistance of mulberry leaf silkworm raw silk. The surface of the woven fabric has a water wave crepe texture. The core yarn shrinks, the breaking strength is improved, and it is naturally located in the center of the yarn. The high breaking elongation of factory-raised silkworm raw silk is effectively utilized.
[0024] The working process of this utility model:
[0025] This utility model discloses a factory-produced raw silk crepe yarn fabric, which is a textile fabric woven by using crepe yarn as the weft yarn and weakly twisted factory-produced raw silk yarn as the warp yarn during the working process.
[0026] By using raw silk from factory-raised silkworms as the warp yarn of the fabric, the production cost of crepe de chine fabric is effectively reduced, and the application fields of factory-raised silkworm raw silk are significantly broadened. Using crepe de chine yarn containing factory-raised silkworm raw silk as the weft yarn serves two purposes: firstly, as the core yarn, its breaking strength is improved, effectively utilizing the high breaking elongation of factory-raised silkworm raw silk; secondly, as the weft yarn, the resulting factory-raised silkworm raw silk crepe de chine has a soft and elastic feel, and leverages the good abrasion resistance of mulberry leaf-fed silkworm raw silk. The woven fabric has a water-wave crepe texture. Compared with existing technologies, this method fully utilizes the advantages of both factory-raised silkworm raw silk and mulberry leaf-fed silkworm raw silk, expanding the application fields of factory-raised silkworm raw silk and reducing the production cost of raw silk crepe de chine, demonstrating significant application value.
[0027] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
