Fent color decision method for dacron/spandex textile

Abstract

The invention relates to a fent color decision method for dacron / spandex textile. The testing method comprises the following steps: unfolding a dyed fent fabric, setting the transverse enumerator at N columns, measuring the transverse total length of the N columns, setting the longitudinal enumerator at N rows, and measuring the longitudinal total length of the N rows; taking a bulk final fabric made of the same material as the fent fabric, similarly setting the transverse enumerator at N columns, measuring the transverse total length of the N columns, setting the longitudinal enumerator at N rows, and measuring the longitudinal total length of the N rows; stretching the dyed fent fabric through a needle plate, and finally forming, wherein the pattern dimensions are as follows: the transverse length h=A*H, and the longitudinal length z=A*Z; according to the final forming process for bulk production, simulating on a small forming machine, feeding the fent fabric, and setting the temperature and the holding time; and using the formed small fabric samples for color contrast. The fent color decision method provided by the invention is simple to operate, and can greatly reduce the difference between bulk samples and small samples during color decision.

Description

technical field [0001] The invention relates to the technical field of proofing color determination of polyester spandex fabrics, in particular to a method for determining the proofing color of polyester spandex fabrics. Background technique [0002] The biggest advantage of spandex is that it has good elasticity and can be stretched several times without breaking. Spandex cannot be woven alone. It is usually woven with other materials, and the most common is blended with polyester. Among them, the proportion of spandex is about 3 Between %-10%. Polyester spandex fabric, often used in tight clothing, has excellent strength and comfortable elasticity. [0003] However, the spandex fiber is subjected to tension during the weaving process, resulting in obvious tensile deformation and accumulating a large amount of residual stress. Although in the follow-up processing, the woven polyester spandex fabric blank will be put into the cylinder for wet pre-shrinkage, after dehydrati...

Problems solved by technology

Although this method is feasible, it requires high experience of craftsmen, and the evaluation is relatively subjective, lacking quantitative evaluation basis. Although the final result of production has improved, it will still cause large differences.
