Embodiment 1

[0028] refer to Figure 1-5 A relaxation device for polyester fabric dyeing, comprising two fixed frames 1, the top between the two fixed frames 1 is rotatably connected with two feed rollers 2, and the bottom between the two fixed frames 1 is rotatably connected with two A discharge roller 3, polyester fabric is connected between the two feed rollers 2 and between the two discharge rollers 3, the feed roller 2 and the discharge roller 3 are located on the same side of the fixed frame 1, and the two fixed frames The side between 1 near the feed roller 2 is rotatably connected with supporting rollers 4 distributed equidistantly in the vertical direction, and the outer walls of the opposite ends of the two fixed frames 1 are fixed on the side far away from the feed roller 2 with equidistant distribution in the vertical direction. electric guide rail 5, and the electric guide rail 5 is set horizontally, the electric guide rail 5 is located between two adjacent supporting rollers ...

Embodiment 2

[0037] refer to Figure 4-6 , a relaxation device for polyester fabric dyeing, the limit rollers 6 between the two fixed frames 1 are equidistantly distributed in the horizontal direction, and the connecting rollers 7 between the two fixed frames 1 are equidistantly distributed in the horizontal direction, The limiting roller 6 and the connecting roller 7 above it are respectively located on both sides of the electric guide rail 5, so that there is a difference in the length of the fabric at the position above and below the limiting roller 6 and the connecting roller 7, and there is a tension or loosening in the dispersed area. difference, so as to increase the rebound strength during the reciprocating tightening and anti-loosening process, so as to enhance the actual relaxation effect on polyester fabrics.

Abstract

The invention belongs to the field of a textile technology, and particularly relates to a relaxation device for polyester fabric dyeing. Aiming at the problem that the actual dyeing quality is influenced by a poor relaxation work effect before polyester fabric dyeing, the invention provides the following scheme that the relaxation device for polyester fabric dyeing comprises two fixed frames, wherein two feed rollers are rotatably connected to the top part between the two fixed frames; two discharge rollers are rotatably connected to the bottom part between the two fixed frames; a polyester fabric is connected between the two feed rollers and the two discharge rollers; the feed rollers and the discharge rollers are located on one same side of the fixed frame; and support rollers equidistantly distributed in the vertical direction are rotatably connected to one sides, close to the feed rollers, between the two fixed frames. According to the relaxation device for polyester fabric dyeingprovided by the invention, the tension of the polyester fabric is relaxed through the intermittent tensioning and locking of cloth, and the relaxation of the bottom part, entering a dyeing jar, of thefabric is reduced, so that an actual dyeing effect is improved; and in addition, the occurrence of the phenomenon that the concentration of a dye is influenced through watering is avoided, so that the follow-up polyester fabric dyeing quality is further ensured.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a relaxation device for polyester fabric dyeing. Background technique [0002] Cloth printing and dyeing is a common process in textile processing. Generally, the raw material of the cloth is conveyed through the conveying roller, so that the cloth is cleaned and dried, and then the stretched cloth is sent to the dyeing tank for dyeing. In the process of dyeing polyester fabrics, since polyester fabrics are elastic knitted fabrics, the spandex will shrink and wrinkle due to uneven stress during the dyeing process, which will affect the actual dyeing effect. Therefore, it is necessary to relax the tension of polyester fabrics. [0003] In the prior art, the relaxation of the polyester fabric is performed by sprinkling water on the surface of the fabric, but if the fabric will recover its elasticity after drying, the relaxation of the fabric cannot be realized. If the fabric absor...
