Abstract

The invention discloses a warp knitting jacquard fabric with a chain-like structure and a production process thereof, and belongs to the field of textiles. In the invention, the first comb GB1 is firstly looped, and then the cushion missing tissues are woven to form floating lines, so that the floating lines are prevented from being overlong, and the loop is formed every few needles. The second comb GB2 is knitted and the pad missing tissue is moved upwards, then is looped and is the same as the first loop forming condition in the first comb GB1, then the pad missing is moved upwards, and the first comb GB1 and the second comb GB2 jointly form a chain structure. The warp and flat structure woven by the third comb GB3 and the warp and flat structure woven by the fourth comb GB4 are symmetrically padded as ground structures, so that the fabric is endowed with good anti-stripping property and certain dimensional stability. The invention synchronously completes the manufacture of the bearing framework and the functional surface layer in one weaving process. The obtained fabric has high strength and high modulus inside and comfort and functionality of the surface, and the problems of increased cost, layering of interfaces and the like caused by a subsequent composite process are avoided.

Description

Warp knitting chain-like structure jacquard fabric and production process thereof Technical Field The invention relates to a warp knitting jacquard fabric with a chain-like structure and a production process thereof, belonging to the field of textiles. Background Along with the improvement of the living standard of people, the expectations of people on the textile fabric are not limited to basic wear performance, but gradually extend to multiple requirements of wearing comfort, decorative effect, industrial application, functional diversity and the like. The cotton, wool and the like are interwoven or blended with chemical fiber filaments in a spun yarn mode, so that the pure spinning difficulty is high, and the fabric is mainly used for improving the hygroscopicity, comfort or natural texture of the fabric and is commonly used in high-end household clothing or decorative fabrics. Glass fiber, carbon fiber and aramid fiber are key raw materials of industrial warp knitting fabrics (such as geogrids and bulletproof materials) by virtue of the characteristics of high strength, high modulus, high temperature resistance and the like, but are easy to brittle fracture and are rarely used in the field of clothing. The viscose and lyocell filaments are gradually increased by combining the environment-friendly idea with the manufacturability of the filaments, so that more comfortable silk-like texture is provided, but the problems of lower wet strength and the like have higher requirements on process control. The raw materials used in large-scale industrial production of warp knitted fabrics are mainly synthetic fiber filaments, wherein Polyester (PET) filaments and nylon (PA) filaments take the absolute predominance. However, the warp knitting fabric successfully spans the wide boundary from daily wear, home beautification to high-end industrial application due to the core advantages of high stability and various designability. Warp knitting technology has become an irreplaceable key solution, especially in the field of industry where precise demands are made on material structure and properties. The traditional warp knitting has higher requirements on the mechanical properties of raw materials, and particularly in the previous warping process, the spun yarns such as cotton, wool and the like are easy to have phenomena of strength loss, hairiness increase, evenness deterioration and the like, and the process conditions of the subsequent machine knitting are often difficult to be satisfied. Therefore, in actual production, chemical fiber filaments with less hairiness and high strength such as terylene and chinlon are mainly relied on, so that the selection range of raw materials is greatly limited. In addition, the existing warp knitting fabric mostly adopts chemical fiber filaments such as terylene, chinlon and the like with poor hygroscopicity and poor wearing comfort, so that the skin-friendly feeling of the clothing is affected, and the visual effect brought by the gloss of the fiber which is not subjected to extinction treatment is poor. Warp knitting fabrics have important application potential in the industrial fields of military industry, construction, protection and the like due to the advantages of good dimensional stability, difficult detachment and the like, but are limited by raw material adaptability for a long time, and are difficult to fully exert the structural advantages. Disclosure of Invention In order to solve the problems, the invention provides a warp knitting jacquard fabric with a chain-like structure and a production method thereof. The invention constructs a stable warp knitting imitation chain structure based on the composite design of weft insertion, pad missing and warp knitting. The fiber is suitable for special fibers with high modulus, low extensibility and the like such as carbon fibers, glass fibers and the like, and provides a new feasible path for developing textile composite materials for high-performance industries. The first comb GB1 is firstly looped, then the cushion-missing tissue is woven to form floating lines, and the floating lines are prevented from being overlong, and the loops are formed every other needle. The second comb GB2 is knitted and the pad missing tissue is moved upwards, then is looped and is the same as the first loop forming condition in the first comb GB1, then the pad missing is moved upwards, and the first comb GB1 and the second comb GB2 jointly form a chain structure. The warp and flat structure woven by the third comb GB3 and the warp and flat structure woven by the fourth comb GB4 are symmetrically padded as ground structures, so that the fabric is endowed with good anti-stripping property and certain dimensional stability, and is far superior to weft-knitted flat knitted fabrics. The loops are in an inclined condition as the yarn bends tend to straighten. The wales of the warp knitting are thus arranged in a zigzag fold in the knitted fabric. The
