Equipment for improving uniformity of dyeing of fabric

Abstract

The invention discloses equipment for improving the uniformity of dyeing of fabric. The equipment comprises a chain rail and a needle board respectively arranged on two sides of the front end of a drying room; a heating device is arranged at the front end of the drying room; the heating device is arranged above the chain rail; the heating device comprises a clamp holder, infrared heating tubes andan infrared heating lamp cover; the infrared heating tubes are arranged on the clamp holder; and the infrared heating tubes are arranged above the chain rail and directly opposite to the two sides ofweaving fabric. The heating device arranged at the front end of the drying room is used for preheating the two sides of the woven fabric. The woven fabric is first passed through the heating device such that two ends of the woven fabric are rapidly heated. Before entering the drying room, the woven fabric exhibits a temperature distribution state in which the temperature at the two ends is high and the intermediate temperature is low, thereby achieving the purpose of preheating the two ends of the woven fabric. After the woven fabric heated by the heating device on the two sides enters the drying room, the defects that the temperature on both sides of the woven fabric is not as high as that of a middle position of the fabric is compensated, so that the styling effect on the two sides of the woven fabric is closer to that of the middle position, the color of a product is more uniform, and the production quality of the product is greatly Improved.

Description

technical field [0001] The invention relates to the technical field of dyeing equipment, in particular to equipment for improving the uniformity of fabric dyeing. Background technique [0002] As we all know, fabrics must be dyed and finished when they are dyed. The process of dyeing and finishing is divided into degreasing, pre-setting, dyeing and post-setting. The existing technology generally uses a drying room to pre-set the fabric. The specific steps are: : Hang the left and right sides of the fabric on the chain needle plate of the sizing machine, the chain drives the fabric into the drying room, and the hot air ejected from the air box in the drying room heats the fabric to make it finalize its shape. [0003] However, the existing technology has the following disadvantages: when the fabric is pre-shaped in the drying room, the hot air ejected from the air box will cause inconsistent air volume when the fabric is heated, which is specifically manifested in the differe...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the inconsistency of the sprayed air volume when the hot air ejected from the existing air box heats the fabric, which leads to the difference in effect between the color of the selvedge and the middle color of the fabric during the dyeing process, and thus greatly increases the number of defective products. efficiency, which reduces the quality of the product and increases the production cost, and provides a device to improve the uniformity of fabric dyeing, which can solve the problem of differences in the setting effect of the selvage position and the middle position of the fabric during pre-setting. It has the advantages of automatic control, high product uniformity and easy operation
