Process for manufacturing sirospun yarn jean facing material

Abstract

The invention discloses a manufacture technique of a siro yarn jean fabric, in which, firstly an advanced siro yarn spinning technology is adopted to manufacture the siro yarn; the spun siro yarn is wound; then the wound siro yarn which is used as a warp is warped, dyed and starched be manufactured into a beam; then the siro yarn is used as the warp and the siro yarn, a rotor spun yarn or a ring yarn are used as an abb to be woven on a loom according to the fabric weave and the weaving technique of the jean to manufacture a grey fabric and finally the grey fabric is made into a finished product through subsequent finishing. As the siro yarn with better quality is adopted as the warp, the method has the advantages of easy yarn splitting, few broken ends, uniform colorizing, reducible sizing quality requirement as well as high heddle draft and reeding efficiency during the dyeing process, clear cut, uniform tension, few broken ends and stopping, few fly wastes in a workshop and on a machine station as well as being beneficial to the cleanness of the workshop and the maintenance of the machine station when weaving.

Description

technical field [0001] The invention relates to a manufacturing process of a denim fabric, in particular to a manufacturing process of a siro yarn denim fabric. Background technique [0002] At present, most of the denim fabrics on the market are produced with rotor-spun yarn. Due to the structure of rotor-spun yarn, which is loose on the outside and tight on the inside, the denim fabric is stiff and not soft enough. In addition, the tension of rotor-spun yarn is about 15% lower than that of ring-spun yarn with the same linear density. When it is used for denim weaving with many pre-weaving procedures and high tension on the machine, it has high requirements for sizing and breaks during the production process. There are many head stops, so that the production efficiency of denim is not high, and the quality of the cloth surface is also relatively poor. Therefore, in recent years, more and more denim factories tend to use ring-spun yarn to produce denim. The tension of rin...

Problems solved by technology

[0003]However, the ring-spun yarn has more hairiness, especially the long hairiness of more than 3mm, which is easy to tangle during the production process, making it difficult to divide the yarn, and the opening is not good during weaving. Clear, more broken ends, higher requirements for sizing

Yarns for denim currently on the market, whether they are rotor-spun yarns or ring-spun yarns, have common problems: poor evenness, yarn hairiness, especially long hairiness, and poor luster

The resulting problems are: high requirements for sizing, easy to produce color difference and uneven color light; there are many flying flowers on the machine and in the workshop, and the environment is poor; there are many hairs on the gray cloth, which puts a lot of pressure on the subsequent finishing and singeing process; Yarn denim has a hard body and poor softness; ring-spun yarn has a lot of hairiness and poor wear resistance, resulting in frequent warp hair loss, size loss, and color loss, resulting in uneven color and light on the fabric; the fabric has dull luster and rough handle, etc.
