A kind of production method of extra-dark polyester interwoven fabric

Abstract

The invention discloses a production method of an extra-dark polyester interwoven fabric, which belongs to the technical field of polyester production methods. It is characterized in that the process steps are: detection of polyester / cotton interwoven gray fabric, pretreatment and dyeing process, high temperature tentering of the semi-finished fabric, washing and dyeing of the semi-finished fabric after high temperature tentering on a jigger dyeing machine to obtain dyed fabric, and making a small sample Inspection of disposal methods: drying of dyed cloth, soft finishing by sizing machine, shaping and stretching, cutting samples to test washing fastness, soaping color fastness, rubbing color fastness, warp and weft shrinkage, and it will be completed after passing the test. The extra-dark polyester interwoven fabric prepared by the production method has stable width, high color fastness and small warp and weft shrinkage.

Description

technical field [0001] The invention relates to a production method of extra dark polyester interwoven fabric, which belongs to the technical field of polyester production methods. Background technique [0002] In the current process, there are many technical problems in the production of ultra-dark polyester interwoven fabrics, the most important ones are the following. [0003] 1. The width of the original grey fabric woven by multiple looms is inconsistent, and there is a gap of 2cm~5cm. After desizing and dyeing of the jigger, the width difference will increase to 3 cm ~ 10 cm, and dark and light edges, edge wrinkles and creases will appear. [0004] 2. When dyeing polyester fiber, due to the large amount of dye, it is easy to cause problems such as tar staining, color staining, and excessive floating color. The current process solves such problems temporarily and is prone to recurrence. [0005] 3. Polyester, cotton or viscose are dyed separately by two-bath method. W...

AI Technical Summary

Problems solved by technology

[0004] 2. When dyeing polyester fiber, due to the large amount of dye used, problems such as tar staining, color staining, and excessive floating color are likely to occur. The current process solves these problems temporarily, and it is prone to repeated

[0005] 3. Polyester, cotton or viscose are dyed separately in two baths. When faced with whether the effect of post-treatment meets the requirements for entering the drying process, the current testing process can only be done according to the water absorption of the dryer (moisture content 75 -85%)-sample cutting-rolling to A-frame-testing index process, this kind of testing method generally takes 3-5 hours to produce results, not only inefficient, but also energy consumption due to the water absorption process increase, leading to an increase in production costs

[0006] 4. After the fabric is softened and pre-shrunk, the post-finishing process will easily lead to unqualified color fastness and shrinkage rate, resulting in fabrics that cannot be repaired, resulting in graded products or inventory
