A kind of production method of colored imitation denim style fabric

Abstract

The invention discloses a production method of a color fabric imitating cowboy style and relates to the technical field of production of woven fabrics. The production method comprises the techniques of slashing, weaving, dyeing gray fabrics, washing and desizing, finishing and the like. Warp and weft yarn components prepared from different materials are selected for weaving and the dyeing difference of the warp and weft yarn components is utilized, so that the whitening effect of dyed fabrics can be realized; a color separating agent with dye-retarding capability is added into a sizing agent for slashing, and is mixed and sized, so that the color separating agent can be uniformly distributed on the surfaces of warp yarns; when the woven fabrics are dyed by adopting active, indigo blue or reducing dye, the dyeing of dye is stopped by a covering area of the woven fabric, and stripe-shaped color spots with different depths in the direction of warp yarns can be obtained after amylase is adopted at later stage for performing desizing treatment, so that the grey effect of traditional yarn dyed denims is realized. The color imitated denim produced by using the production method has the advantages of vivid style, abundant colors, simple process, high production efficiency, high color fastness and the like.

Description

technical field [0001] The invention relates to the technical field of production of woven fabrics, in particular to a production method of textile denim. Background technique [0002] Traditional denim manufacturing is mainly obtained by sizing and weaving after warp dyeing. Regardless of whether the warp yarn is dyed in rope, piece yarn or hanging ring dyeing, its production efficiency is lower compared with fabric dyeing, and in order to achieve the whitening effect in the later stage , needs to be washed and finished. During the washing process, the color will fade seriously, which is easy to cause staining problems. In addition, the entire processing process of traditional denim is lengthy and complicated, the production efficiency is low, the production cost is high, and it will also cause serious pollution problems. For colored denim, which has been in urgent market demand in recent years, the traditional yarn-dyed weaving process is more difficult to match colors, a...

For colored denim, which is in urgent market demand in recent years, the traditional yarn-dyed weaving process is more difficult to match colors, and the product's color light is not stable enough, and the reproducibility is poor, which cannot meet customer needs.

[0003] In recent years, in order to solve this problem, some manufacturers use cotton, viscose and other cellulose fibers as warp yarns and polyester and other synthetic fibers as weft yarns when weaving, and use the difference in dyeing properties of different fibers to directly dye the woven fabrics. Dyeing, so as to obtain denim-like fabrics, but such imitation fabrics are seriously stained, and a slight error in the control of dyeing conditions will cause the dew to not stand out, and it is difficult to reflect the hazy effect of "gray gray" unique to yarn-dyed fabrics
