Description

Production process of leopard-line-imitated jean fabric
Technical Field
A production process of leopard print imitated jean fabric belongs to the technical field of jean fabric production processes.
Background
The existing jean fabric is single in color, free of patterns or monotonous in patterns, free of stripe feeling, low in appearance grade or common after being washed by water. And either the fabric is too soft and lacks stiffness due to the design process of the fabric, and the fabric is easy to wrinkle and low in grade; or is too stiff and uncomfortable to wear.
At present, in order to increase the pattern diversity of the denim fabric, the fabric cost is generally improved by a printing or embroidering mode, and the final pattern effect is poor, unnatural and low in grade, so that the individuation of the denim fabric cannot be reflected. In the prior art, the softness and stiffness are controlled only by adjusting the sizing or dyeing time and the track number of the warp and weft yarns to solve the softness and stiffness problems, and the effect of taking account of both the softness and the stiffness cannot be achieved.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art, and provides a production process of the leopard print imitating jean fabric which has the similar leopard print effect and is moderate in softness and stiffness.
The technical scheme adopted by the invention for solving the technical problems is as follows: a production process of the leopard print imitated jean fabric is characterized by comprising the following steps: the warp and weft yarn matched cotton contains 10-15 wt% of regenerated cotton, and the yarn twist coefficient is 335-345; the dyeing process comprises two dyeing steps, wherein a warm water washing step is carried out twice between the two dyeing steps, the warm water washing step adopts flowing water for washing, and the water flow rate is 0.003-0.005 cubic meter/s; the sizing rate of the sizing process is set to be 11-13%, the winding tension of the sizing machine is set to be 2500-2800N, and the flat yarn tension is set to be 2000-2200N.
