Problems solved by technology

Due to the characteristics of silk itself---smoothness and suppleness, there are very serious problems such as layer difference, unwinding and entanglement in the degumming and dyeing of silk bobbins, which are extremely unfavorable for winding after dyeing, and the problem of bobbin forming has always restricted the dyeing of silk bobbins. development of

Abstract

The invention discloses a dyeing method of real silk cone package, which can solve the problems of layer difference, cylinder detachment and entanglement which appear in the dyeing of the real silk cone package. The method comprises the steps of yarn loosening and dyeing, and is characterized in that: the step of yarn loosening is carried out for real silk cylinder loosening in a numeral winding manner, and the crossing angle of adjacent real silk winding wires is 30 degrees; the step of dyeing is carried out by that: dye and a leveling agent are added at room temperature, the rate of temperature rise is controlled, heat preservation is carried out after half amount of glauber salt is added, the other half amount of the glauber salt is added after the temperature is continuously raised, then, heat preservation is carried out again, calcined soda is added finally, heat preservation is carried out for the third time after the calcined soda is added, and dyed yarns waiting for post treatment are obtained after residual liquid is removed. The method has the advantages that the layer difference between the interior and the exterior of the cone package is reduced to below 0.24, thus greatly reducing the problems of photosensitive discoloration, large layer difference and dyeing defect rehandling which are caused by sensitive colors; the method solves the problems of cylinder detachment and entanglement in the dyeing of the real silk cone package, enhances the stability and efficiency of the dyeing of the real silk cone package, and improves the product quality.

Description

technical field [0001] The invention relates to a cheese dyeing method, in particular to a method for dyeing a real silk fabric cheese. Background technique [0002] Silk fabrics are deeply loved by consumers because of their comfortable wearing and unique health care functions. Due to the characteristics of silk itself---smooth and supple, the degumming and dyeing of silk bobbins have very serious problems such as layer difference, unwinding and entanglement, which are extremely unfavorable for winding after dyeing. The problem of bobbin forming has always restricted the dyeing of silk bobbins. development of. [0003] Traditional silk dyeing uses skeined silk to be dyed on a jet machine, which has many disadvantages: long production process and low efficiency; mainly manual operation, high labor intensity; The yield is low; low-twisted silk or untwisted silk is easy to produce fuzz, and the variety is limited, which affects the development of yarn-dyed products.
