Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a manufacturing process and product of a wrinkle-resistant and tear-resistant waistband webbing. Background Technology

[0002] Currently, traditional garment waistbands commonly suffer from problems such as wrinkling, deformation, tearing, and high shrinkage rates during use. Especially after repeated wear, washing, and stretching, ordinary webbing easily loses elasticity, develops wavy deformation, curls or wrinkles at the edges, severely affecting the appearance, comfort, and lifespan of the garment. Due to the inconsistent shrinkage rates of the webbing and the fabric, finished garments are prone to wrinkling and unevenness at the waistband after washing. While existing technologies offer some methods to improve webbing structure or materials, they have not fundamentally solved the problem of synergistic optimization of wrinkle resistance, tear resistance, and dimensional stability. In particular, a complete and controllable manufacturing process is lacking to achieve stable mass production of high-performance waistbands. Summary of the Invention

[0003] In view of this, in order to solve the problems existing in the technical background, the present invention proposes a manufacturing process and product for wrinkle-resistant and tear-resistant waistband webbing. Specifically, it includes the following: A manufacturing process for a wrinkle-resistant and tear-resistant waistband webbing includes the following steps: S1, Raw material preparation and warping: Polyester fiber, 70D / 2 high F number nylon and high elastic spandex are used as the base raw materials and warped in proportion; S2, Weaving: The warped yarn is woven simultaneously with the twill bottom using a double-layer jacquard process. The surface layer uses a plain jacquard interweaving structure, the middle layer uses a core-spun yarn and spandex composite structure, and the bottom uses a high-F nylon twill structure. The tension is monitored and adjusted in real time during the weaving process. S3, High-temperature setting: The woven webbing is set under high-temperature conditions; S4, Performance Inspection: After shaping, the jacquard dimensions and wrinkle resistance parameters of the webbing are inspected. If they meet the standards, batch shaping is carried out. Furthermore, in step S1, the polyester fiber is a fiber material that has been processed to improve its feel. Furthermore, in step S2, the weaving equipment is a high-speed jacquard weaving machine, and the stability of the process is checked and controlled at fixed times and locations during the weaving process. Furthermore, in step S3, the high-temperature setting temperature and time are set according to the characteristics of the webbing material to achieve closed-loop control of the webbing's anti-wrinkle function. Furthermore, in step S4, the performance test includes a recovery test of the webbing after repeated stretching and gripping, and a shrinkage test after washing. A wrinkle-resistant and tear-resistant waistband webbing is prepared using the manufacturing process of the aforementioned wrinkle-resistant and tear-resistant waistband webbing. The above technical solution has the following beneficial effects: The webbing of this invention, after being high-temperature set, possesses excellent shape memory, allowing it to return to a flat state even after multiple washes and prolonged wear, without wrinkling or curling, making it especially suitable for people with protruding abdomens. Utilizing a multi-layered composite structure and high-strength materials, the webbing maintains a smooth surface and smooth edges even after 30 repeated tears, significantly improving durability. After 100 repeated stretches and 30 gripping cycles, the webbing quickly returns to its original shape with minimal elasticity loss, resulting in a long service life. Detailed Implementation The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1: A manufacturing process for a wrinkle-resistant and tear-resistant waistband webbing includes the following steps: S1, Raw material preparation and warping: Polyester fiber, 70D / 2 high F number nylon and high elastic spandex are used as the base raw materials and warped in proportion; S2, Weaving: The warped yarn is woven simultaneously with the twill bottom using a double-layer jacquard process. The surface layer uses a plain jacquard interweaving structure, the middle layer uses a core-spun yarn and spandex composite structure, and the bottom uses a high-F nylon twill structure. The tension is monitored and adjusted in real time during the weaving process. S3, High-temperature setting: The woven webbing is set under high-temperature conditions; S4, Performance Inspection: After shaping, the jacquard dimensions and wrinkle resistance parameters of the webbing are inspected. If they meet the standards, batch shaping is carried out. The basic raw materials selected in this invention include polyester fiber, 70D / 2 high-filament nylon, and high-elastic spandex. The polyester fiber requires special processing to improve its hand feel and increase its softness. These raw materials are mixed in a pre-designed ratio that optimizes the elasticity, strength, and hand feel of the final product, and then warped to prepare a neatly arranged and evenly tensioned warp yarn system for subsequent weaving. The weaving process utilizes a high-speed jacquard weaving machine of the Zhongjinyuan brand (model 520) or similar performance. The surface layer of the webbing employs a plain jacquard interweaving structure, which determines the surface pattern and texture of the webbing. The interlayer uses a special core-spun yarn and high-elastic spandex composite structure, which is the core of the webbing's high elasticity and excellent resilience. The core-spun yarn process enhances the yarn's strength and abrasion resistance. The bottom layer uses high-filament nylon woven in a twill structure. The relatively soft twill structure, combined with the delicate characteristics of high-filament nylon, provides a soft and comfortable feel against the skin. Throughout the weaving process, the tension of the warp and weft yarns must be monitored and adjusted in real time to maintain a stable weaving speed. Process parameters must be checked regularly to ensure the stability and consistency of this complex multi-layered weaving process. The woven fabric requires high-temperature setting, a crucial step in achieving its wrinkle-resistant properties. The fabric is subjected to high-temperature setting at specific temperatures and times required by the process. This process stabilizes the internal structure of the fibers, eliminates internal stress, and thus "locks in" the shape and size of the fabric, giving it excellent shape memory and wrinkle resistance. The high-temperature setting process parameters need to be precisely set and adjusted according to the characteristics of the raw materials used to achieve "closed-loop control" of the wrinkle-resistant function, ensuring stable performance for each batch of products. After high-temperature setting, the webbing must undergo rigorous performance testing before it can be mass-produced and shipped. The main testing items include: 1) Size and appearance inspection: Check whether the jacquard size meets the standard and whether the webbing is flat and free from deformation; 2) Functional recovery test: Simulate actual use scenarios, repeatedly stretch the webbing continuously, and observe its ability to return to flatness after being gripped and held still; 3) Shrinkage test: The dimensional change rate of the webbing is tested through a standard washing process to ensure an extremely low shrinkage rate. Only after all parameters, especially wrinkle resistance parameters, are confirmed to meet the preset high standards can the batch of webbing be released and the final batch finalization be completed. The waistband webbing prepared by the above process integrates the advantages of all the aforementioned processes, and is a functional webbing with a multi-layer composite structure: its surface layer is plain jacquard, the middle layer is a core-spun yarn spandex elastic layer, and the bottom layer is a high-F nylon twill comfort layer. This product has been tested and verified to have the following characteristics: the waistband remains flat and new after 90 days of normal wear and washing; it quickly recovers its flatness after 100 repeated stretching; the shrinkage rate after washing is less than -1%; and the fabric remains flat and the edges do not waviness after 30 repeated tearing. The product perfectly solves the technical defects of traditional waistband webbing, such as easy wrinkling, easy deformation, high shrinkage rate, and poor tensile strength. It is suitable for various clothing products with high requirements for waistband performance. The basic principles and main features of the present invention have been described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention. All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the invention is defined by the appended claims and their equivalents.
