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] The weft elastic fabric of 75D viscose filament in the warp direction and 40D bi-component T400 polyester yarn in the weft direction is used as the typical pre-shrinking treatment grey fabric of the device of the present invention. figure 1 The embodiments of the present invention will be described in detail. The width of the grey fabric is 175cm and the weight is about 75g / m². The grey fabric is unwound from the cloth roll A (1) and sent to the water tank through the overfeed roll C (2), passes through the rolling surface between the upper and lower squeezing rollers (8) under water on the right side of the pendulum roller (7), and passes through the pendulum roller. The left side of the roller is wound onto the cloth roll B(3) through the overfeed roller D(4). The linear speed of feeding the grey fabric into the water tank is controlled at 35m / min, the overfeed rate is controlled at 2%, the diameter of the pendulum roller is 8cm, the axial width is 180cm, and the pendu...

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 water-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, for example, elastic fabrics containing polyester bicomponent fibers (composite yarns composed of PET and PTT polyesters) need to be pre-shrunk in a water bath to fully release their potential stress and elasticity. Generally, the fabric washing and pre-shrinking treatment can adopt open-width treatment, rope treatment or roller washing treatment. Elastic fabrics, especially thin fabrics, are suitable for open-width treatment. The jigger is a kind of intermittent open-width processing equipment widely used at present. It consists of two cloth rolls, an immersion roll and a water tank. The two cloth rolls can be rotated forwards and backwards, thereby alternately feeding and unwinding and rewinding and rewinding. Th...
