Dyeing process of all-polyester chiffon fabric

Abstract

The invention discloses a dyeing process of an all-polyester chiffon fabric and relates to the technical field of chiffon fabric dyeing. Key points of the technical scheme are that the dyeing processcomprises the following steps: (1), open-width refining; (2), pre-shrinking; (3), drying; (4), pre-shaping; (5), alkali reduction; (6), washing; (7), dyeing; (8), finishing agent coating; (9), acid pickling; and (10), back-to-cylinder cleaning. The dyeing process disclosed by the invention has the benefit that the effect of effectively improving the blackness of the chiffon fabric can be archivedthrough increasing the dyeing degree and improving the visual sense.

Description

technical field [0001] The invention relates to the technical field of chiffon dyeing, in particular to a dyeing process of all polyester chiffon. Background technique [0002] Chiffon fabric is a kind of fabric made of polyester or silk as raw material for warp and weft, and twisted left and right. Chiffon fabric has good texture and color effect, and the fabric is ultra-thin. Due to the smooth warp and weft of the shelley fabric, it is particularly easy to breathe, and the sufficient weight reduction treatment in the dyeing makes the fabric feel particularly soft, so it is widely loved by people. Among them, a large part of the chiffon fabric produced in my country is sold. To the Middle East, but affected by the local religion and culture, the chiffon fabrics sold to the Middle East countries in my country are usually dyed black in advance, and the higher the blackness, the more popular it is with the local people. [0003] However, in the prior art, black chiffon fabrics...

Problems solved by technology

[0003] However, in the prior art, black chiffon fabrics generally use 10% (o.w.f) disperse black S-2BL as the dyeing agent, and then the gray fabric is sequentially passed through pre-shrinking, washing, presetting, alkali reduction, dyeing, and rinsing. , dehydration, opening and setting steps to complete the dyeing of chiffon fabrics, but the chiffon fabrics dyed in this way must rely on the alkali weight reduction process to improve the hand feeling, but the surface of the gray cloth after alkali weight reduction treatment will form pits , so that the visual color becomes worse, resulting in a reddish color of the dyed finished product, which is a manifestation of insufficient blackness, so it is difficult to meet the needs of customers in the Middle East, and the existing technology has not yet solved the alkali reduction process The remaining visual problems have prevented the blackness of chiffon fabrics from being improved
