Abstract

The invention relates to a preparation method of a knitted denim fabric, which comprises the following steps of: using blenched combed yarns as front-side raw materials of a looming process; using indigo blue OE (Open-End) yarns as reversed side raw materials of the looming process; weaving by an improved triangular single-sided weft original knitting machine to obtain blank cloth; and sequentially carrying out water washing, enzyme washing, enzyme inactivation, rinsing, water washing, softening processing, drying and ironing on the blank cloth to obtain the knitted denim fabric. The preparation method of the knitted denim fabric has simple process and low cost; the softness of the existing woven denim fabric in the market is improved; the air permeability of the woven denim fabric is improved; and the wearing comfort of the woven denim fabric is improved.

Description

technical field [0001] The invention belongs to the field of denim fabric preparation, in particular to a preparation method of knitted denim fabric. Background technique [0002] Since the birth of Levis's first canvas jeans in 1847, over the past 100 years, although the denim fabric has been continuously developing from the original thick type to the light and thin type, there are also denims of different thicknesses and styles on the market. Fabrics, however, are still limited to woven products. With the continuous improvement of people's living standards, the requirements for clothing fabrics are getting higher and higher, and the demand for fabric diversification is also getting higher and higher. Denim must not only maintain its original simple and generous style, but also require It can have the characteristics of lighter and thinner fabric, softer hand feeling, better ventilation and more comfortable wearing. It can ensure that the finished garment can completely fi...
