Piece dyeing method of cotton binding textiles

Abstract

The invention discloses a piece dyeing method of cotton binding textiles, which is characterized in that the invention has the concrete processing process comprising the steps of singeing, desizing, light scouring and bleaching, pre-setting, rendering, color fixation soap washing, forming and preshrinking. The invention has the advantages that the cotton binding textiles obtained through being processed by the method have the advantages of uniform cloth surface color, good luster, high intensity and low washing shrinkage rate, and in addition, the production processing efficiency of the method is high. In addition, the mixed alkali treatment is adopted in the light scouring and bleaching process, so the invention ensures that the processed cotton binding textiles have certain whiteness and water absorption performance, in addition, the plant intensity of the textiles can not be damaged to the furthest extent, and the narrow width of the textiles caused by shrinkage in the following processing work procedure can be avoided through improving the hydrophilicity of the textiles and widening the width of the textiles via the pre-setting process.

Description

technical field

[0001] The invention relates to a processing method for cotton viscose fabrics, in particular to a piece dyeing method for cotton viscose fabrics. Background technique

[0002] Cotton / viscose blended or interwoven fabric not only has the toughness of cotton, but also has the advantages of good gloss, good moisture absorption and strong drape of viscose, which improves the quality of textiles. However, cotton and viscose fabrics have different hues and tones on the fabric due to the different affinity of cotton and viscose to dyes. In severe cases, it will cause white spots on the fabric and uneven dyeing.

[0003] At present, the dyeing of cotton viscose fabrics is mainly realized by cold pad-batch dyeing or jigger dyeing, but these two dyeing methods have problems such as low processing efficiency and difficult control of color difference between the head, tail and edge of the fabric, which brings inconvenience to production.
