A device for testing the elasticity of textile fabrics

Abstract

The invention discloses an elasticity testing device for textile fabrics, which comprises a workbench, a vertical board, a supporting board, a supporting leg, a vertical board, a first spring, a slide plate, a bolt, a second spring, a splint, a motor, a runner, a belt, Shaft, gear, pressure roller, extension plate, first electric push rod, block, second electric push rod, fixed plate, third spring, connecting rod, push plate, bottom plate, switch, side plate, connecting shaft, limit Plate, chute, slide bar, connecting plate, turning bar and the third electric push rod. The elastic testing device for textile fabrics has a simple structure, and the movement of the limit plate is beneficial to fix the reel wrapped with the fabric, which is convenient for the delivery of the fabric during measurement; while the fabric is being pulled, the cooperation between the splint and the ring is effective. It is conducive to the clamping of the fabric; the rotation of the pressure roller is conducive to the movement of the fabric to the shift position, and the measurement of the elasticity of the fabric is facilitated by limiting the rotation of the pressure roller, and it is also conducive to the measurement of fabrics of different lengths.

Description

technical field [0001] The invention relates to a test device, in particular to an elasticity test device for textile fabrics, which belongs to the technical field of textile fabric applications. Background technique [0002] Textile fabrics are knitted fabrics. According to the weaving method, there are two types of weft-knitted fabrics and warp-knitted fabrics. Weft-knitted fabrics are often made of low-elastic polyester yarns or special-shaped polyester yarns, nylon yarns, cotton yarns, and wool yarns. Plain stitch, variable flat stitch, rib plain stitch, double rib plain stitch, jacquard stitch, terry stitch, etc. are woven on various weft knitting machines. The purpose of spinning is to wind the cotton yarn entering the factory Into a package with a certain structure and specifications, suitable for knitting production. During the spinning process, it is necessary to eliminate some defects on the yarn, and at the same time make the yarn have a certain uniform tension, a...

Problems solved by technology

However, for the elasticity test of textile fabrics, since the rolled fabric needs to be opened and placed on the equipment during the test, it is inconvenient to operate and increases the amount of operation; and the end of the fabric needs to be checked when measuring. Clamping at the bottom, usually using multiple fixing clips for fixing, resulting in increased difficulty of operation, which is not conducive to fast fixing; and when testing, it is necessary to perform multiple measurements according to the length of the fabric and compare them, resulting in the need for each measurement. The trouble of adjusting the length of the fabric reduces the speed of the test and affects the efficiency of the test
