Method and apparatus for dyeing and sampling soft bag

Abstract

The dyeing and striking-off process with soft bag includes the following steps: setting spread cloth or yarn to be dyed inside one soft waterproof bag; injecting dye solution in proper amount into the bag; sealing the mouth of the bag to maintain the dye solution inside the bay and to form dyeing and striking-off bag; stretching the dyeing and striking-off bag with some fixture, and turning and driving the bag to make the dye solution flow inside the bag to penetrate cloth fiber for homogeneous dyeing. The dyeing and striking-off apparatus includes dyeing and striking-off bag, bearing stage for the bag to be set on and fixed, and dyeing machine with support frame, spraying unit, sliding unit, driving unit, hot water tank, cold water tank and airtight door. The present invention has the advantages of homogeneous dyeing, saving in dye solution, low cost and no pollution.

Description

1. Technical Field [0001] The invention relates to a printing and dyeing equipment and method, in particular to a soft bag body dyeing and proofing method that uses a disposable dyeing proofing bag for dyeing and turning over or pressing the surface of the bag to make the dyeing solution in the proofing bag flow fully. Method and device. 2. Background technology [0002] Existing dyeing proofing methods, such as figure 1 As shown, the cloth 11 is wound and placed in the cylinder cup 12, and then the dye solution is injected and the cover 13 is tightened to form a test color proofing cup 1; figure 2 As shown, the test color proofing cup 1 is placed on the rack 21 of the dyeing testing machine 2 to continuously rotate, and the color test proofing cup 1 is continuously heated by the heating device 22 inside the body to achieve the purpose of dyeing. [0003] The existing dyeing and proofing methods have the following shortcomings in the implementation: 1. Because the fabric 11 is ...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in existing products, and provide a method and device for dyeing and proofing of soft bags, and improve the existing method of dip-dyeing cloth with proofing cups into disposable proofing bag dip-dyeing Cloth, so as to overcome the problem that the cloth is easy to be dyed or wrinkled; when the cloth or yarn is dip-dyeed, it can be carried out in an ultra-low bath ratio of 1:3-1:8, which has the advantages of saving dyeing liquid and reducing the burden of subsequent processing, and at the same time The negative impact on environmental pollution can be reduced; the proofing bag of the present invention is cheap, and is a disposable design, does not need to store a large number of proofing cylinder cups, and has no disadvantages of cleaning and pollution
