Abstract
Description
Technical Field
[0001] This invention relates to a weaving method for a woven-look weft-knitted elastic terry fabric with left and right twill weave, belonging to the technical field of weft-knitted terry fabrics. Background Technology
[0002] As living standards improve, consumers have higher demands for clothing wearing experience and fabric performance. Unrestricted wearing and removal, diverse styles, and high elasticity and comfort have become core requirements. Improving fabric elasticity and enriching fabric styles are key technological directions to meet these demands.
[0003] Weft-knitted terry fabrics are typically woven on a single-sided knitting machine using a terry sinker, with the ground yarn and terry yarn fed in through double yarn guides. Traditional weaving methods result in a loose terry structure, complex weaving processes, and the terry loops are prone to shifting under tension, affecting the fabric's appearance. Furthermore, the fabric has a limited style and can only be used on one side, making it unsuitable for high-end weft-knitted applications. To improve the looseness of the terry loops and enhance elasticity, current techniques often add polyester filaments to the ground yarn, but the overall elasticity of the fabric remains significantly insufficient. Woven twill fabrics, on the other hand, have a stiffer feel, and their elasticity relies on spandex core-spun yarn, leading to lengthy processing steps and low production efficiency.
[0004] Currently, the industry commonly uses a composite method of short fibers, polyester filaments, and spandex to prepare weft-knitted terry elastic fabrics, aiming to balance fabric feel, elasticity, and appearance. However, there are three major technical challenges in industrial production: First, poor weaving matching; the loop lengths of composite fibers of different types, specifications, and ratios vary significantly, easily leading to quality defects such as uneven fabric surface, large weight fluctuations, blurred texture, uneven elasticity, and loose loops during synchronous weft knitting. Second, high difficulty in dyeing and finishing; the temperature resistance and heat shrinkage properties of short fibers, polyester fibers, and spandex are all factors to consider. The differences in yield and dyeing characteristics are significant. In addition, high-denier polyester fibers require low-temperature dyeing. Traditional processes not only result in incomplete pretreatment and poor dyeing evenness, but also easily lead to problems such as color difference and low color fastness, and even cause fiber damage and loss of elasticity in spandex. Thirdly, the shaping stability is insufficient. The shrinkage rates of multiple fiber components are inconsistent. Under low-tension shaping conditions, it is difficult to simultaneously ensure the fabric's dimensional stability and elastic recovery rate, and it is also impossible to balance the functional finishing requirements such as soft hand feel and hydrophilicity. This seriously restricts the large-scale production and application of high-quality composite weft-knitted terry fabrics. Summary of the Invention
[0005] To address the aforementioned issues, this invention provides a method for weaving a simulated woven weft-knitted elastic terry fabric with left and right twill weave. The simulated woven weft-knitted elastic terry fabric with left and right twill weave is made by composite weaving of terry yarn and ground yarn on a single-sided circular knitting machine. The terry yarn and ground yarn are woven together to form a complete loop row. Depending on the weft knitting structure of the fabric, the simulated woven weft-knitted elastic terry fabric with left and right twill weave includes twill terry fabric. The weaving method includes the following steps: S1. Material Selection: Combed cotton staple yarn is selected as the terry yarn, which can make the pattern clear and reduce hairiness; polyester filament is selected as the ground yarn, which can make the fabric base tight and flat, forming a skeleton; elastic spandex yarn is selected as the filling yarn, which has good abrasion resistance and tensile recovery. S2. Weaving: According to the needle arrangement diagram and cam configuration diagram, configure the corresponding level of knitting needles and the needle exit cam, plain needle cam, and needle-containing cam. Input the target yarn length value on the digital operation screen. The yarn enters the knitting area through tension control. The cylinder drives the knitting needles to rotate. Under the control of the cam track, the knitting needles bend the yarn into loops and interlock with each other. The yarn is pulled by the tensioning mechanism to form the greige fabric. The tensioning mechanism also rolls or swings the greige fabric downwards. S3. Pretreatment: The woven fabric undergoes refining and desizing to remove machine oil, sizing agents, and foreign fibers applied during weaving. Although polyester does not contain natural impurities, pretreatment is still crucial. Removing machine oil, sizing agents, and foreign fibers applied during weaving provides a foundation for uniform dyeing. S4. Dyeing: Disperse dyes are used to dye the pretreated fabric. During the dyeing process, the pH value of the dye bath is controlled to be stable at 5, and the cooling rate is controlled. After dyeing, reduction washing is performed to remove the floating color. S5. Setting: Setting the dyed fabric under low tension conditions. In some embodiments, the temperature of the refining and desizing treatment in step S3 is below 80°C; refining and desizing can be performed by using a highly efficient refining agent and treating the sample thoroughly at a temperature below 80°C.
[0006] In some embodiments, in step S4, a disperse dye with good lifting power and uniformity is selected. This high-performance fabric has extremely high requirements for color fastness. Special high-denier filaments require low-temperature dyeing, as high temperatures will destroy the perfect macromolecular chain structure formed by super-stretching. The heat preservation time also needs to be extended. The pH value of the dye bath is kept stable at around 5, and a sodium acetate buffer system is used to maintain it. Preferably, the control of the cooling rate in step S4 includes: first rapidly cooling to 80°C, and then slowly cooling to below 50°C before removing from the dye bath.
[0007] In some embodiments, in step S5, the setting time is 30 to 60 seconds; after dyeing, a thorough reduction cleaning is performed to remove excess dye and improve color fastness; setting is performed under low tension conditions to obtain stable dimensions, desired style, and necessary functionality; and hydrophilic finishing and hand feel finishing are performed on the fabric.

[0014] Advantages and effects of the present invention: This invention addresses the technical challenges of existing weft-knitted terry fabrics, such as loose loops, insufficient elasticity, limited style, difficulty in matching multi-fiber composite fabrics during weaving, high requirements for dyeing and finishing, and poor shape stability. Through an integrated process involving combed cotton / polyester filament / spandex composite materials, segmented needle weave design, low-temperature dyeing and finishing, and low-tension setting, it achieves the production of high-quality weft-knitted elastic fabrics with a simulated woven twill effect, balancing appearance, elasticity, hand feel, and stability for large-scale production. Specifically, it includes: 1. Diverse styles of imitation twill with outstanding appearance and texture: The design adopts a 3-segment needle and 4-segment needle structure with left and right twill weaves, and uses weft knitting technology to achieve the visual effect of woven twill. It breaks through the limitations of traditional twill fabrics with a single style and can only be used on one side. The texture is clear and there is less hair, which meets the diverse style needs of knitted outerwear.
[0015] 2. The fabric has a tight structure and excellent elasticity, resulting in superior performance: It uses combed cotton staple yarn as the loop yarn, polyester filament as the skeleton ground yarn, and spandex yarn as the elastic filler yarn. The ground yarn is fully stitched with plain stitch to lock the loops, which not only solves the problem of loose and easily shifted loops in traditional fabrics, but also greatly improves the elasticity and stretch recovery of the fabric, taking into account both soft hand feel and structural stability.
[0016] 3. Precise weaving control and stable fabric quality: By precisely matching the needle pitch, cylinder diameter, and loop length, combined with the optimized configuration of knitting needles and triangular tracks, the problem of uneven fabric surface, weight fluctuation, and elasticity deviation caused by large differences in the length of multi-fiber loops is effectively solved. The finished weight and width are adjustable to meet the needs of different seasons.
[0017] 4. The dyeing and finishing process is gentle and controllable, with high color fastness and fiber integrity: It adopts low-temperature refining and desizing at temperatures below 80℃, combined with pH5 buffer dyeing bath, segmented cooling dyeing and reduction cleaning, which is suitable for the low-temperature dyeing requirements of high-denier polyester filaments, avoiding loss of elasticity of spandex and fiber damage, with good uniformity, small color difference and color fastness meeting the standards.
[0018] 5. Low-tension setting balances stability and functionality, suitable for industrial production: Setting under low tension conditions simultaneously achieves dimensional stability and optimized elastic recovery rate, while also considering hydrophilic finishing and hand feel finishing. It solves the setting problem caused by the different shrinkage rates of multiple fibers. The process is simple, efficient, and can be mass-produced. Attached Figure Description
