Problems solved by technology

Specifically, the hydrophobic lipid layer on the surface of the cashmere fiber and the highly cross-linked and dense outer cuticle prevent the diffusion and transfer of the dye molecules to the inside of the fiber through the scale layer. The fabric has poor penetrability, whitening phenomenon, light and uneven color, and needs long-term high-temperature steaming to help the dye to diffuse into the fiber, causing damage to the cashmere fiber and degrading the quality

Abstract

The invention discloses a pretreatment slurry for cashmere fabric digital printing and a printing technology of cashmere fabric digital printing. The pretreatment slurry is composed of sodium alginate paste, plant seed gelatine KCA-90 paste, TCEP, penetrant, urea, ammonium sulfate and water; the printing technology of cashmere fabric digital printing comprises the steps of sizing; conducting drying at the temperature of 40 DEG C for 10 min; conducting steaming at the temperature of 85 DEG C for 4-5 min; conducting cold washing at the room temperature for 10 min; conducting soaping at the temperature of 60 DEG C for 5 min with soaping agent A being 2g / L, and alginate lyase being 1 mg / L, and Na2CO3 being 0.5g / L; conducting hot washing at the temperature of 60 DEG C for 5 min; conducting cold washing at the room temperature for 5 min. By combining the pretreatment processing and the digital printing technology, the obtained printing cashmere fabric is high in tinctorial yield, uniform in color, free of phenomenon of grinning of white ground, clear in floral pattern margin, and good in color fastness.

Description

technical field [0001] The invention relates to the field of digital printing, in particular, the invention relates to a cashmere fabric digital printing pretreatment slurry and a digital printing process. Background technique [0002] Cashmere is a natural fiber with many excellent properties that other fibers cannot match. It is called "diamond fiber" and is favored by consumers. From the perspective of international clothing consumption and textile technology development trends, the demand for high-end cashmere printed products is increasingly strong in the international market, but my country's current deep-processing technology and models of cashmere products can no longer meet the increasingly diverse development needs of the market. Due to the limitations of cashmere fiber characteristics and traditional weaving techniques, most of the patterns and patterns of cashmere products in my country are realized by weaving methods such as jacquard and intarsia, which makes it...
