Problems solved by technology

However, this method is not suitable for weft elastic fabrics, especially for weft elastic fabrics containing polyester bicomponent fibers. Shrinkage treatment in a tension-free state will cause this type of fabric to shrink excessively in the weft direction and crepe, making it difficult to Made into a fabric with a flat and smooth surface

Embodiment Construction

[0006] With warp direction 75D viscose filament, weft elastic fabric of weft direction 40D two-component T400 polyester yarn is used as the typical pre-shrinking gray cloth of the device of the present invention, refer to figure 1 Embodiments of the present invention will be described in detail. The gray cloth has a width of 175cm and a weight of about 75 grams per square meter. The gray cloth is unrolled from the roll roll A (1) and sent into the water tank through the overfeed roll C (2), passes through the right side of the pendulum roll (7) and passes through the rolling surface between the upper and lower extrusion rolls (8) under water, and passes through the pendulum roll (7). The left side of the roll is taken up by the overfeed roll D (4) onto the cloth roll B (3). The linear speed of the gray cloth into the water tank is controlled at 35m / min, the overfeed rate is controlled at 2%, the diameter of the swing roller is 8cm, the axial width is 180cm, the distance betwe...

Abstract

The invention relates to an open-width washing device for preshrinking fabric. The open-width washing device comprises two cloth rollers, two overfeed rollers, a sink, two roller oscillating mechanisms and a pair of squeeze roller drums, wherein the two groups of rollers are synchronized by adopting variable-frequency speed regulation to control the cloth rollers A and B and the overfeed rollers C and D, the fabric passes through the sink in a relaxed state by maintaining the overfeed rate of the two overfeed rollers to be 1-4 percent, the two groups of roller oscillating mechanisms are arranged in the sink, the pair of squeeze roller drums externally packed by rubber skin is arranged at the lower part of the sink, therefore, the peripheral contour line of the integrally axial section of the upper roller drum forms a convex radian of 3.85-4.55 degrees, the peripheral contour line of the integrally axial section of the lower roller drum forms a concave radian of 3.86-4.60 degrees, the fabric is properly squeezed by the upper and the lower roller drums, and the pressure between the upper and the lower roller drums is controlled in the range from 5kg to 10kg. The open-width washing device provided by the invention is particularly suitable for preshrinking thin weft-elastic fabric.

Description

technical field [0001] The invention relates to a low-tension open-width washing pre-shrinking device for fabric pre-shrinking treatment, which is especially suitable for the treatment of thin elastic fabrics. Background technique [0002] Some elastic fabrics, such as elastic fabrics containing polyester bicomponent fibers (composite filaments composed of PET and PTT polyesters), need to be preshrunk in a water bath to fully release their potential stress and elasticity. Generally, fabric washing pre-shrinking treatment can be treated by open width treatment, rope treatment or drum washing treatment, and elastic fabrics, especially thin fabrics, are suitable for open width treatment. Dye jigger is an intermittent open-width processing equipment widely used at present. It consists of two cloth rolls, a submerged roll and a water tank to form the basic working mechanism. The two cloth rolls can rotate positively and negatively, so that the cloth feeding, unwinding and rewind...
