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.

Embodiment 1

[0041] Step 1: spread out the proofing mesh fabric that has been dyed (the color is dark black) and is judged to be qualified after comparing with the customer-supplied standard sample. A unit structure similar to a fish shape that appears horizontally on the fabric surface is defined as a vertical Row, enumerates 20 vertical rows horizontally, and measures the total horizontal length H of the 20 vertical rows d20 . Similarly, a unit structure with the same shape appearing in the longitudinal direction on the cloth surface is defined as a row, enumerates 20 rows in the longitudinal direction, and measures the total longitudinal length Z of the 20 rows d20 . Take the final bulk fabric of the same material as the proofing fabric, and use a similar method to enumerate 20 longitudinal rows in the horizontal direction, and measure the total horizontal length H of the 20 longitudinal rows f20 . The vertical enumerator counts 20 horizontal rows, and measures the total vertical len...

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...
