Description

Single-layer jacquard warp-knitted fabric with dynamic ventilation and adjustment functions and manufacturing method thereof Technical Field The invention relates to the technical field of textile, in particular to a single-layer jacquard warp-knitted fabric with a dynamic ventilation adjusting function and a manufacturing method thereof. Background With the continuous improvement of the demands of consumers on the functionality, the aesthetic property and the comfort of the garment fabric, the market has increasingly grown on the fabric with jacquard effect, good elasticity and intelligent air permeability. Warp knitting jacquard technology becomes a key means for developing complex pattern fabrics due to the strong pattern programming capability. The jacquard effect of rich meshes, plain cloth and the like can be realized by arranging the jacquard device in the traditional single needle bar warp knitting machine. However, the single-layer jacquard fabric in the prior art is often single in function, or focuses on the pattern expression to sacrifice the dynamic comfort of the fabric, or has elasticity but lacks the 'intelligent' response characteristic that the shape and the function are obviously changed after the external force is applied. The fabric with variable development state in the prior art generally depends on double guide bars or complex double-layer structures, and has insufficient comprehensive consideration on three-dimensional texture and elastic recovery. On the other hand, in the field of three-dimensional fabrics, the prior art adopts a high boiling water shrinkage yarn combined with a jacquard opposite-draw process to form a concave-convex three-dimensional structure, but the technology is generally applied to a double-needle bed structure or has dyeing limitation. In addition, the conventional elastic fabric mostly adopts a weft knitting structure, and although the elasticity is good, the pattern expressive force and the structural stability are inferior to those of warp knitting products. Disclosure of Invention The invention aims to provide a single-layer jacquard warp-knitted fabric with a dynamic ventilation adjusting function and a manufacturing method thereof, which can integrate three functions of high elasticity, three-dimensional texture and dynamic ventilation adjusting, break through the limitation of single function of the traditional fabric, respond to human body movement, realize intelligent ventilation and improve wearing comfort. In order to achieve the aim, the single-layer jacquard warp-knitted fabric with the dynamic ventilation adjusting function comprises a single-layer structure fabric knitted by a single-needle bar warp-knitted machine provided with Shan Guka devices, wherein the fabric comprises a surface base layer area and a jacquard functional area, the surface base layer area is formed by knitting ground guide bars by adopting inelastic yarns to form a supporting framework of the fabric, and the jacquard functional area is formed by knitting at least one jacquard guide bar by adopting elastic yarns and is embedded into the surface base layer. Further, the jacquard functional area comprises a first type functional area and a second type functional area, wherein the first type functional area is woven with first type meshes and first type columnar protruding structures, and the second type functional area is woven with second type meshes and second type columnar protruding structures. Further, the preset aperture of the second type of mesh is smaller than that of the first type of mesh. Further, the organization of the surface basal layer area is formed by two ground combs through a surface basal layer opposite-pulling net formed by a warp-flat organization, the organization of the first type of functional area is formed by knitting a jacquard guide bar JB1.1 by adopting a knitting chain organization and a warp-flat organization, and the organization of the second type of functional area is formed by knitting a jacquard guide bar JB1.2 by adopting a process of knitting a warp-velvet organization and a warp-flat organization. Further, the inelastic yarn is nylon DTY yarn, the elastic yarn is core spun yarn with nylon DTY as outer spun fiber and spandex as core yarn, preferably, the outer spun fiber is 30D/24F nylon DTY, the core yarn is 40D spandex, and the amount of the spandex is controlled to be 5% -12% of the total amount of the yarn.
