Embodiment

[0031] The dyeing method of tencel wool gray cloth comprises the following steps:

[0032] (1) Put the gray cloth into the desizing machine, add the desizing and refining solution according to the bath ratio of 1:10 for desizing and refining treatment, the desizing and refining solution consists of amylase 15g / L, lubricant 2g / L, softener 2g / L, composition of preservative 3g / L, add acetic acid to make the PH of the desizing and refining solution be 6.5, the desizing and refining temperature is 80°C, the treatment time is 90min, take out the gray cloth and carry out cleaning and drying treatment;

[0033] (2) Put the gray cloth processed through step (1) into the dye vat containing dye mixed solution 1 to dye the wool component in the gray cloth. The dye mixed solution 1 includes direct orange S 4% (owf), sodium chloride 10g / L, color fixing agent 30g / L, wetting agent 2g / L, retarder 6g / L, and add glacial acetic acid to it, make the pH of the solution be 3.5, the dyeing bath ratio...

Abstract

The invention discloses a method for dyeing tencel wool grey cloth, which comprises the following five steps: desizing and refining grey cloth, dyeing wool components in the grey cloth, soaping and drying after dyeing, dyeing tencel components, and soaping and drying after dyeing, namely dyeing the tencel wool grey cloth by using a two-bath method. According to the invention, desizing treatment is carried out before dyeing, and refining enzymes such as amylase and cellulase are used for desizing and refining the raw grey cloth, so that the purpose of efficient desizing can be achieved, fibers of wool and tencel cannot be damaged, and the desized grey cloth is full and soft in hand feeling. The wool component in the tencel wool grey cloth is dyed by using the direct dye in the high-temperature environment of 90-100 DEG C, so that the hand feeling of the wool can be kept, the wool component can be better colored, the tencel component is dyed by using the direct dye in the environment of 60-80 DEG C, the coloring can be uniform, and the color and the hand feeling of the wool cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of gray cloth dyeing, in particular to a method for dyeing Tencel wool gray cloth. Background technique [0002] Tencel is a pure natural regenerated fiber, which is produced by solvent spinning technology based on ammonium oxide, which is completely different from the previous production method of viscose fiber. Because the solvent can be recycled, it is not harmful to the ecology, and it is also known as the 21st century viscose fiber. The ingredient of Tencel is fiber diesel, and its raw material is trees in nature. It has the advantages of soft and smooth hand feeling, good hygroscopicity, and high wet strength. Wool is a natural protein fiber with no hollow tube inside and a scale structure on the surface. The maximum moisture regain is about 13%. It has strong hygroscopicity and can absorb more than 60% of its own weight in water. Even if it is used all year round, it can still keep it comfortable. s...
