Embodiment 1

[0034] This embodiment provides a dyeing method for improving the metamerism of the yarn-dyed auxiliary material matching cloth body, which includes the following steps:

[0035] (1) Select the yarn-dyed auxiliary material yarn combed 60 / 2 pure cotton yarn ratio to the yarn-dyed fabric sample polyester-cotton cloth, determine the sample dyeing formula (see table 1 original cylinder KH031327), and the yarn-dyed auxiliary material yarn carries out sample dyeing according to the sample dyeing formula, Obtain a sample dyed trim yarn. The sample dyeing formula is shown in Table 1.

[0036] (2) Carry out trial weaving and enzyme washing of the sample dyed auxiliary yarn to obtain a sample finished product, and judge by human eyes that there is metamerism between the sample finished product and the yarn-dyed fabric sample under different light sources, and the metamerism value is greater than 2.0.

[0037] (3) According to the metamerism value, adjust the sample dyeing formula, add ...

Embodiment 2

[0080] This embodiment provides a dyeing method for improving the metamerism of the yarn-dyed auxiliary material matching cloth body, which includes the following steps:

[0081] In this example, 2.0% of EVE N BLUE GG dye is added on the basis of the original dye formula. The cylinder number of the bulky cloth is DJ527590, the bulky cloth is made of polyester cotton, and the finishing method is enzyme washing.

[0082] Yarn-dyed accessories cylinder number KH053322, yarn-dyed accessories ingredients: combed 60 / 2 pure cotton yarn, try to weave collar and sleeves, finishing method: resin + enzyme wash + garment without water.

[0083] After the bulk fabric body and yarn-dyed accessories are dyed, take the bulk fabric body as the standard and the yarn-dyed accessories as the reference sample, and use the color light source: D65, A lamp, and CWF three light sources to measure the metamerism value, as shown in the table 4.

Embodiment 3

[0101] This example provides a dyeing method for improving the matching of yarn-dyed auxiliary materials to match the metamerism of the fabric. The difference between this method and Example 2 is: the cylinder number of the large-scale fabric is DJ118840, and the composition of the large-scale fabric: pure cotton, finishing Method: open width mercerizing. Yarn-dyed accessories cylinder number KH062780, ingredients of yarn-dyed accessories: combed 60 / 2 mercerized cotton yarn, trial weaving collar and sleeves, finishing method: ready-made garments do not wash.

[0102] After the bulk fabric body and yarn-dyed accessories are dyed, take the bulk fabric body as the standard and the yarn-dyed accessories as the reference sample, and select the color light sources: D65, A lamp, and TL84 three light sources to measure the metamerism value, as shown in the table 5.

Abstract

The invention discloses a dyeing method for relieving the same-light different-spectrum phenomenon of a yarn-dyed auxiliary material matched cloth body. The method includes the following steps of firstly, comparing dyeing auxiliary yarn with a dyeing cloth sample to determine a sample dyeing formula, and conducting sample dyeing on dyeing auxiliary yarn according to the sample dyeing formula to obtain sample dyeing auxiliary yarn; secondly, conducting the trial weaving process and the trial finishing process on the sample dyeing auxiliary yarn to obtain a sample finished product, and judging whether the same-light different-spectrum phenomenon happens to the sample finished product and the dyeing cloth sample under different light sources or not; thirdly, when the same-light different-spectrum phenomenon happens to the sample finished product and the dyeing cloth sample under different light sources, adjusting the sample dyeing formula according to the same-light different-spectrum value, and obtaining the increased or decreased dye consumption on the basis of the sample dyeing formula to obtain a large cargo formula; fourthly, conducting large cargo dyeing according to the large cargo formula to obtain the large cargo cloth body. The dyeing method can effectively reduce the same-light different-spectrum phenomenon of the dyeing auxiliary material and the dyeing cloth sample.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a dyeing method for improving the matching of yarn-dyed auxiliary materials to cloth body metamerism. Background technique [0002] When knitting piece dyeing to produce solid-color varieties, non-clean-color accessories (collars, sleeves, ribs, etc.) and special yarn varieties (mercerized yarn, pure polyester yarn, etc.) The amount of dye, the composition of the cloth body, and the finishing are different, resulting in the phenomenon of metamerism between the yarn-dyed fabric accessories and the yarn-dyed fabric body. Metamerism refers to the phenomenon that two substances show the same color under one light source, but different colors under another light source. This phenomenon is called metamerism. The emergence of metamerism will inevitably lead to color differences under different light sources and a decline in customer satisfaction with products. Contents of the invention [00...
