Description

A special shrinking equipment for textile printing pretreatment

technical field

The invention relates to the field of textile production equipment, in particular to a special shrinking equipment for textile printing pretreatment.

Background technique

In the production process of textiles, it is necessary to carry out multiple treatments on the finished fabrics to achieve the best product performance. In order to make the textile fabrics soft, it is necessary to shrink the textiles. Shrinkage treatment refers to the finishing process that uses physical methods to reduce the shrinkage of fabrics after immersion in water to reduce shrinkage, also known as mechanical pre-shrinkage finishing. In mechanical pre-shrinking, the fabric is wetted by spraying steam or spray, and then mechanically squeezed in the warp direction to increase the buckling wave height, and then dried by loosening. The shrinkage rate of the pre-shrunk cotton cloth can be reduced to less than 1%, and the softness of the fabric will also be improved due to the mutual extrusion and rubbing between the fibers and yarns.

The pre-shrinking equipment in the prior art has the following technical defects: 1. In the pre-shrinking process of textiles, steam injection is required. The steam injected is transported through pipelines and sprayed out from the air injection holes to directly irradiate the surface of the textile. ; If the width of the jet is smaller than the width of the textile surface, it will lead to insufficient wetting of the textile, resulting in poor shrinkage of the textile; if the width of the jet is larger than the width of the textile surface, the excess jet steam will be lost to the air, Waste is generated; it is difficult to control the amount of steam when spraying steam on textiles, and the steam sprayed can only be sprayed on one side of textiles, and the wetting rate of textiles is low. 2. When pre-shrinking textiles, only one side of the textiles is heated and pre-shrunk. The textiles have not been repeatedly folded and heated to pre-shrink. The pre-shrinking process of the textiles is uneven and insufficient.
