Problems solved by technology

However, the function of traditional denim fabric is relatively single, and there are certain defects in comfort, so it is difficult to meet people's higher requirements.
Looking at the current fabric market at home and abroad, it is not difficult to find that domestic denim fabrics are still in the low-end market, with low added value and fierce price competition. Most manufacturers have meager profits and brand development is also at a low-level operation stage.
In particular, the application of new fiber raw materials and advanced finishing technology to improve the added value of denim fabrics still has a large gap with foreign countries.

Abstract

The invention relates to a flame-retardant jean fabric. The flame-retardant jean fabric is prepared by comprising the following steps: (1) placing jean fabric in a jig dyeing machine, adding water and desizing enzyme for processing, then discharging liquid and washing with water; (2) enzyme washing: adding the desized jean fabric, water and neutral cellulose enzyme into the jig dyeing machine, performing temperature rise, discharging liquid and cleaning with water; (3) flame retardant padding-batching: mixing tetrakis hydroxymethyl phosphonium chloride, urea, etherified hexamethylol melamine resin and penetrating agent JFC to obtain flame-retardant finishing liquid, padding and batching the jean enzyme-washed fabric into the flame-retardant finishing liquid, performing twice padding and twice batching; (4) ammonia fumigation: performing ammonia fumigation to the flame retardant-padded-and-batched jean fabric in an ammonia fumigation flame-retardant machine; and (5) later-stage arrangement: performing once padding and once batching to the ammonia-fumigated jean fabric in hydrogen peroxide, and storing after padding and batching; and drying after being washed. According to the flame-retardant jean fabric, the excellent flame-retardant property of the jean fabric is endowed, and the added value of the product can be improved.

Description

technical field [0001] The invention relates to a fabric production process, in particular to a flame-retardant denim fabric, which belongs to the technical field of textile and clothing. Background technique [0002] Because of its rough style, simple and natural, practical and durable, denim fabrics are widely used in the fields of high-end fashion and general tooling. However, the function of traditional denim fabric is relatively single, and there are certain defects in comfort, so it is difficult to meet people's higher requirements. Looking at the current fabric market at home and abroad, it is not difficult to find that domestic denim fabrics are still in the low-end market, with low added value and fierce price competition. Most manufacturers have meager profits and brand development is also at a low-level operation stage. In particular, the application of new fiber raw materials and advanced finishing technology to improve the added value of denim fabrics still has...
