Special-shaped three-dimensional knitted fabric and manufacturing method thereof

Abstract

The invention relates to a special-shaped three-dimensional knitted fabric and a manufacturing method thereof, which relate to the knitted fabric. The special-shaped three-dimensional knitted fabric with at least one of an upper surface and a lower surface being a concave-convex special-shaped curved face, and favorable air permeability, support performance and shearing resistance, and the manufacturing method thereof are provided. The special-shaped three-dimensional knitted fabric comprises an upper fabric layer, a middle fabric layer and a lower fabric layer, wherein the upper fabric layer or / and the lower fabric layer is / are provide with a concave-convex curved face(s) in a knitted longitudinal direction(s); and the middle fabric layer is formed by connecting yarns with flexural rigidity. According to a fabric structure and a texture requirement, required materials of the upper fabric layer, the required lower fabric layer and the middle fabric layer are selected; according to structural features of the fabric, the yarns are sewed on a guide bar; according to special-shaped structural features of the fabric, warp run-in of the fabric is set, and a distance between two needle beds can be adjusted in real time when the fabric is knitted in different horizontal lines according to variation in thicknesses of the different horizontal lines of the fabric; and a drawing device draws the knitted textile from the needle beds when knitting is carried out simultaneously.

Description

technical field [0001] The invention relates to a knitted fabric, in particular to a special-shaped three-dimensional knitted fabric and a manufacturing method thereof. Background technique [0002] In recent years, compared with polyurethane cushioning materials, three-dimensional knitted fabrics have better supporting performance and air permeability, and are gradually used in home textiles, clothing, medical, industrial and other fields. However, the surface of the previous three-dimensional knitted fabrics is a planar structure, which can only be shaped by molding at high temperature in applications with special-shaped structure requirements, and the thickness range is also limited. [0003] Chinese patent CN201321530Y discloses a knitted fabric and its production machine: on a double-needle bed warp knitting machine, polyester or nylon monofilaments with a diameter of 0.06-0.95 mm are used to weave mesh cloth with a thickness of 5-30 mm. [0004] Chinese patent CN10138...

AI Technical Summary

Problems solved by technology

However, the changing device between the needle groove plates cannot meet the real-time adjustment of the spacing during the production process, and can only be adjusted in the parking state, and the swing amplitude of the bar during the yarn laying process cannot meet the needs of the adjustment of the spacing of the needle beds. Real-time adjustment, so it does not have the ability to produce concave and convex fabrics

The thickness of the fabric also has certain limitations, which cannot meet the requirements of thicker fabrics
