Abstract

An embodiment of the invention provides clearance-variable warp-knitted spacer fabric and a preparation method thereof. The preparation method includes: adopting a double-needle bed Raschel warp knitting machine to knit warp-knitted spacer fabric with clearance between fabric faces as a first clearance; utilizing slitting technology to divide the warp-knitted spacer fabric into a warp-knitted spacer fabric fragment with spacer thread length being a second clearance, wherein the second clearance is smaller than or equal to the first clearance, and a fabric face is included in the warp-knitted spacer fabric fragment; folding the warp-knitted spacer fabric fragment by taking a central line of the fabric face as symmetric axis, and connecting spacer threads at corresponding positions by presetlength to form the warp-knitted spacer fabric with a clearance between two fabric faces not being unique. By the method, the clearance-variable warp-knitted spacer fabric with the clearance between the fabric faces not being unique can be prepared, and limitation that a clearance between two fabric faces of warp-knitted spacer fabric is unique in conventional technical schemes is overcome.

Description

technical field [0001] The invention relates to the technical field of weaving methods and woven fabrics, in particular to a variable-gauge warp-knitted spacer fabric and a preparation method thereof. Background technique [0002] The warp-knitted spacer fabric is a double-sided fabric produced on a double-needle bed warp knitting machine with two parallel needle beds, and is formed by connecting the upper and lower fabric surfaces through spacer yarns. Warp knitted spacer fabrics have excellent properties, such as energy absorption, shock absorption and compression resistance, etc., and are widely used in packaging and transportation, clothing, home textiles, shoe uppers, cushions and other fields. At the same time, the warp-knitted spacer fabric can also form a composite material with high composite performance with the matrix material. Due to the good integrity and light density of the warp-knitted spacer fabric, it has a wide range of engineering applications. [0003] ...
