Problems solved by technology

Although the elongation ability of knitted fabrics is much better than that of woven fabrics, the wear resistance, washability and durability of knitted fabrics are not as good as woven fabrics
However, compared with the controllability of warmth retention, moisture permeability and heat dissipation, the stretchability of woven fabrics, especially the stretchability of plain weave fabrics with a simpler fabric structure, is very difficult to predict and determine.

Abstract

The invention discloses an extensibility presetting method of plain weave fabric. The method comprises the following steps: prefetching the warp radius and weft radius of to-be-manufactured fabric; wherein the number of the warp yarns in the weft unit length and the number of the weft yarns in the warp unit length are equal; wherein the warp-wise length and the weft-wise length are the warp-wise breaking strength of the to-be-manufactured fabric; setting a stress coefficient of the warp yarns; and calculating the elongation of the plain weave fabric according to the equation set. The inventiondiscloses a plain weave fabric manufacturing method with set elongation. The method comprises the following steps: selecting warp yarns and weft yarns for manufacturing plain weave fabric, the methodcomprises the following steps: acquiring warp radius, weft radius, elastic coefficient of warp and breaking strength of warp, calculating according to an equation set to obtain multiple groups of alternative solutions, trial-manufacturing the fabric according to the alternative solutions, measuring the elongation of the fabric, and manufacturing the plain weave fabric according to related physical quantity parameters when the elongation error range required to be manufactured is met. Material selection and structural design of plain weave fabric can be guided according to the required fabricelongation, and a large amount of trial and error cost is avoided.

Description

technical field [0001] The invention relates to the technical field of fabric weaving, in particular to a method for presetting the extensibility of plain weave fabrics and a method for making plain weave fabrics with set extensibility. Background technique [0002] In sports competitions such as swimming and track and field, the performance of the competitive clothing worn by the players can significantly affect the performance of the players. Therefore, it is necessary to measure the performance of the fabric from multiple angles, or to guide the actual production by constructing a prediction model of the fabric performance, so as to reduce the test cost. For example, the Chinese patent document CN103439188B published on July 15, 2015 records a method for predicting the tear resistance of composite plain weave fabrics, which theoretically deduces the tear resistance prediction of infinitely large composite material fabrics under any crack length. The formula facilitates t...
