Description

A double-sided jacquard weaving process

technical field

The invention relates to fabrics, in particular to a double-sided jacquard weaving process.

Background technique

With the demand of the market and the improvement of living standards, people have higher and higher requirements for daily necessities. For fabrics, it is not only light, breathable, comfortable, healthy, and environmentally friendly; at the same time, textile fabrics are also required to be fashionable and beautiful. There are already some formed textile fabrics on the market, but the surface can only achieve a single-color effect. To achieve multi-color effects, subsequent processing such as printing, coating or hot pressing must be carried out. The operation is complicated, the cost is high, and it is not environmentally friendly. At present, although the jacquard machines on the market can also wear yarns of more than two kinds of materials for weaving, the warp knitted fabric obtained by weaving also has more than two colors after dyeing. However, due to the limited means of the existing technology, more than two colors are obtained.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a double-sided jacquard weaving process, the pattern of the double-needle spacer fabric produced by it is distinct, has a good three-dimensional effect visually, and simplifies the production process at the same time , greatly saving costs.

In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is: a double-sided jacquard jacquard knitting process, the double-needle spacer fabric is produced on a double-needle bed double jacquard warp knitting machine, and the double-needle bed double jacquard warp knitting The knitting machine production includes a front needle bed and a rear needle bed. The double-needle spacer fabric adopts a computer-designed jacquard pattern. It is characterized in that: the double-needle spacer fabric uses 7 bars for weaving. Arrange bar GB1, bar GB2, Jacquard bar JB3.1, Jacquard bar JB3.2, Jacquard bar JB4.1, JB4.2, and Jacquard bar GB5 in sequence on the rear needle bed, with specific weaving steps as follows:
