Embodiment

[0023] Select 100Kg 66D mulberry silk for cheese dyeing, and its technological process is:

[0024] 1. Winding process: SSM car is used, the speed is 490-510 rpm, and the thread tension is 1.5N. The fixed weight of the package after the winding process is 0.55-0.6kg / piece, and the density is 0.35-0.4g / cm 3 , with a fixed weight of 0.55kg / piece and a density of 0.37g / cm 3 for the best. Each package is wrapped by an elastic fiber sleeve and then enters the pre-treatment process.

[0025] 2. Pre-treatment process, degumming enzyme process, after filling the dye vat with water at a liquor ratio of 1:20, add degumming enzyme WSL 1%-2% Owf, penetrant CN 0.5g / L, soda ash 1-3g / L, and dissolve. Wherein, the soda ash is added in an appropriate amount according to the pH value of the degumming enzyme treatment solution, and the pH value of the degumming enzyme treatment solution is adjusted to 10-10.5. The solution in the dye vat was heated to 50°C and operated for 30 minutes, and th...

Abstract

The invention provides a dyeing method of a mulberry silk cheese, comprising the following procedures: slack-spooling, pre-processing, dehydrating, drying, dyeing, postprocessing, dehydrating and drying. The dyeing method is characterized in that the constant weight of the cheese for slack-spooling is 0.55-0.6kg / pcs, the density is 0.35-0.4g / cu.cm., and the cheese is wrapped by an elastic fiber sleeve and then is subjected to the pre-processing procedure; and secondary slack-spooling is carried out on the cheese after the procedures of pre-processing, dehydrating and drying, the constant weight of the cheese is still 0.55-0.6kg / pcs, the density is 0.35-0.4g / cu.cm., and the cheese performed with secondary slack-spooling is wrapped by the elastic fiber sleeve and then is subjected tp the dyeing procedure. In the invention, slack-spooling and secondary slack-spooling can effectively overcome various adverse factors affecting the density and the shape of the cheese in the procedures; and situations of uneven dyeing and great inner-outer color difference owing to overlarge density do not occur, and cheese collapse owing to too small density does not occur, thus ensuring the dyeing quality of the cheese. The dyeing method has the outstanding advantage of effectively solving unstable dyeing quality of the mulberry silk cheese.

Description

technical field [0001] The invention belongs to a dyeing method of the textile industry, in particular to a dyeing method of mulberry silk cheese. Background technique [0002] Mulberry silk is one of the earliest animal fibers used by human beings. Since mulberry silk is not polluted in the production process from mulberry cultivation to silkworm reeling to silk reeling, it is a green product respected by the world. And because it is a protein fiber, it is a porous material, has good air permeability and excellent hygroscopicity, and is known as the "Queen of Fibers" by the world. As a textile raw material, mulberry silk is not only soft, close-fitting, warm and breathable, but also has a variety of health care effects on the human body due to its green and healthy characteristics. Therefore, mulberry silk is one of the excellent fibers for making high-end clothing fabrics. [0003] The dyeing of mulberry silk is carried out after making it into a cheese yarn. At present,...
