Embodiment 1

[0039] Taking Shilin yellow as an example, the sample to be dyed is 16 pure cotton cheeses with a weight of 88kg. The method and steps of dyeing the cheeselin color are described in detail. The present invention uses a bobbin winder as the bobbin loosening device, specifically, a sea stone flower bobbin winder with good quality and high precision on the market is preferred. Before the dyeing starts, the packages need to be loosened. Due to the original package yarn on the market, the yarn is tightly wound on the package and the density is high, making it difficult to dye the yarn in the inner layer, which is very unfavorable for subsequent uniform dyeing, so it is necessary to loosen the original package yarn deal with. However, if the cheese is loosened so that the density is too small and the weight is too light, the production efficiency will be reduced. Specifically, one cheese can be loosened to 700-750g, 0.35-0.39g / cm 3 One bobbin, the present embodiment preferably lo...

Abstract

The invention discloses a method for dyeing Shilin color on a bobbin. The method includes following steps: loosening the bobbin: loosening cheese; pretreating: using a pretreating aid to performing apretreating process conducive to dyeing on the cheese; dyeing: adding caustic soda into a dyeing vat at normal temperature, sucking prepared Shilin dye into the dyeing vat at normal temperature, enabling the dyeing vat to run for 16min, increasing temperature to 58 DEG C at a temperature increase rate of 1 DEG C / min, sucking in sodium hydrosulfite, and holding temperature for 40min; after-treating: discharging water in the dyeing vat, and performing aftertreatment processes like washing and softening on dyed cheese, wherein a weight ratio of the cheese, the pretreating agent, the caustic soda,the Shilin dye and sodium hydrosulfite is 440:225:200:4267:63. Chlorine bleach resistant color fastness of the cheese in the Shilin color obtained by using the method can reach Grade 4 (the testing standard is AATCC 188), and light fastness can reach Grade 4 of 20h.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a method for dyeing a cheesecloth color with a cheesecloth. Background technique [0002] Shihlin color is a general term for colors dyed by shihlin dyes (vat dyes). Shihlin-colored fabrics are very popular among consumers. In the industry, winding machines are mostly used for dyeing, referred to as bobbin dyeing. Cheese dyeing is a method of dyeing yarn. Cotton yarn is wound on a bobbin to become a bobbin, and then the bobbin is dyed. Due to the strong reducibility of Shihlin dyes, Shihlin dyes are very easy to color on the yarn during the dyeing process, that is, Shihlin dyes are colored very quickly, which can greatly improve the dyeing efficiency. But it is also because of the fast dyeing of Shilin dyes, if the various processes of cheese dyeing are not well controlled, it is very easy to cause color flower and layer difference in the cheese yarn, and finally the ...
