Corduroy fabric is a kind of cotton fabric with fine bristles, which is soft and comfortable, warm and wear-resistant. The process of making corduroy cloth is mainly as follows:
1. Fine bristle process: The main process of making corduroy cloth is to form a layer of fluff on the surface of the cloth through fine bristle treatment to improve the thermal performance of the cloth. This process is generally divided into two steps: first, the fabric through dyeing, styling and other pre-treatment process; Then, the treated fabric is brushed by a cotton gin or a blanking machine to make its surface fine and evenly covered with a layer of short fluff, thus forming the unique texture of corduroy fabric.
Second, fine weaving process: the weaving process of corduroy cloth is also very critical, and it is generally woven with advanced textile machines to ensure the quality and feel of the cloth. In the weaving process, it is necessary to choose the appropriate yarn composition and weaving density, while controlling the weaving tension and speed, so that the corduroy cloth presents a uniform and fine texture, while maintaining good tensile properties.
Third, dyeing and printing process: the color and pattern of corduroy fabric are completed by dyeing and printing process. In the dyeing process, it is necessary to choose the appropriate dyes and dyeing agents, and use the appropriate dyeing methods, such as immersion, spraying, curling, etc., to ensure that the color of the corduroy fabric is bright, uniform, and firm. The printing process is on the basis of dyeing, through template printing or rotary printing, to add patterns to the corduroy cloth to increase its decorative effect.
Fourth, post-treatment process: After dyeing and printing corduroy cloth, it is also necessary to carry out a series of post-treatment processes to achieve the required quality and effect. Common post-treatment processes are drying, finishing, shaping and so on. The drying process is to dry the dyed or printed fabric so that the color is firm and the pattern is clear. Finishing process is to use the finishing machine to finish and scrape the fluff on the surface of the cloth to make it more flat and smooth. The shaping process involves heat treating the fabric so that it retains the desired shape and texture.
To sum up, the production process of corduroy fabric mainly includes fine bristles, fine weaving, dyeing and printing, post-processing and other links, through the careful treatment of these processes, in order to produce a unique texture and decorative effect of corduroy fabric.
