specific Embodiment 1

[0024] A method for imitation dyeing of pure cotton black and red plaid fabric, comprising gray yarn→loose winding→chamfering→yarn loading→yarn pretreatment→yarn dyeing→dehydration→whitening→washing, refixing, Dehydration→drying→winding→dyed yarn; among them:

[0025] Among the gray yarns, the yarn specification is: 32S pure cotton yarn;

[0026] In the loose winding, the base yarn is wound from the paper bobbin to the plastic bobbin, the winding speed is 500-600m / min, and the winding density is low, which is convenient for pre-treatment and dyeing in the subsequent process;

[0027] In the described yarn pretreatment, the process prescription is as follows:

[0028]

[0029] The temperature is 90°C, and the time is 40 minutes;

[0030] In the yarn dyeing, the black yarn and the red yarn are respectively dyed, which includes the following steps: bobbin preparation→into the dyeing vat→adding sodium starch→adding alkali agent→hot water washing (85°C, 5min)→ Cold water wash...

Abstract

The invention discloses a worn-imitated dyeing method of pure cotton black red plaid fabric. The method comprises the steps of blank yarn, slack winding, chamfering, yarn loading, yarn pretreatment, yarn dyeing, dehydrating, white discharge, water washing, re-color fixing, dehydrating, drying, winding and yarn weaving. In the method, the step of white discharge is based on dyed yarn, so that the black red plaid fabric reaches a consistent worn-imitated effect; the black discharge dye and the red discharge dye are different in molecular structure, so that the black yarn and the red yarn use different dyeing processes and different white discharge processes for yarn white discharge separately, after weaving, uniform, consistent white discharge effect is achieved, deep texture worn-imitated effect is realized; when discharge dyes are used for dyeing, the use amount of a color fixing agent is 25-50% of normal use amount for dyeing and is convenient for white discharge, after white discharge, color fixing is performed again to make the color fastness of the yarn normal.

Description

technical field [0001] The invention belongs to the field of fabrics in the textile industry, and in particular relates to a method for imitation dyeing of pure cotton black and red plaid fabrics. Background technique [0002] Imitation old clothes are trendy clothes. It uses a kind of ultra-fine dye Sandozol T with low affinity to cellulose to adsorb on the cationized fibers, so that the fibers are colored, and the washing fastness is moderate. After the treatment, the surface of the fiber is evenly etched white, and the fuzzy white star effect is obtained. The clothes have an old-fashioned feeling and are particularly soft to the touch, which meets the modern people's requirements for personalized and comfortable clothing, and has good development prospects and good economic benefits. benefit. [0003] Disclosed are a fabric dyed with reactive dyes treated with old-fashioned treatment and a method for old-fashioned treatment thereof. It is to put the fabric in the air-fl...
