Problems solved by technology

During the process of this process, the original fiber defects in the sliver are not easy to remove, and the surface defects of the single-dyed polyester-cotton blended yarn formed by weaving and dyeing are generally difficult to eliminate by manual repairing. Downgraded use, the risk of quality compensation is much higher than that of other types of yarn

Embodiment Construction

[0009] 1. Preparation of polyester / cotton blended single-dyed yarn with a linear density of 18.5tex and a JC / T blending ratio of 50 / 50:

[0010] 1. Cotton distribution:

[0011] The principle of cotton fiber matching: choose 3.5 grade cotton.

[0012] The principle of cotton distribution emphasizes quality first, overall arrangement, overall consideration, guaranteeing key points, looking forward and backward, keeping a steady flow, thoroughly understanding both ends, and rational allocation; On the basis of many varieties of production, according to different quality requirements, it can not only ensure the use of cotton for key varieties, but also make overall arrangements; looking ahead is to fully consider the situation of raw cotton in stock, semi-finished products in the workshop, and raw cotton procurement to ensure supply; It is to prolong the use period of each batch of raw cotton as much as possible, and strive to achieve multi-mark production, at least 6-8 marks; t...

Abstract

The invention relates to the technical field of spinning, in particular to a production method of single-dyed polyester cotton blended yarn. The method comprises the following steps of performing lapforming on cotton pre-drawing slivers and polyester pre-drawing slivers which are respectively prepared by opening picking, cotton carding and pre-drawing to obtain polyester cotton mixed rolls, performing lap doubling on the polyester cotton mixed rolls to obtain polyester cotton rolls, and sequentially carrying out combing, two-pass drawing, roving and spinning on the polyester cotton rolls to obtain the single-dyed polyester cotton blended yarn. When the cotton pre-drawing slivers and the polyester pre-drawing slivers are combined, the cotton pre-drawing slivers and the polyester pre-drawing slivers are doubled twice, so that the two kinds of fibers are mixed twice before combing, the mixing uniformity of polyester and cotton fibers is greatly improved, the mixing effect is improved, transverse strips of a single-dyed polyester-cotton yarn cloth cover are effectively reduced, and the two fibers are combed together after being uniformly mixed, so that the problems of slub nep defectsand the like of the cloth cover can be reduced. The process has low requirements on the quality of the raw cotton, and the grade of the used raw cotton can be reduced to 3-4 grades.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production process of single-dyed blended yarns. Background technique [0002] Single-dyed polyester-cotton yarn means that only one of the fibers is dyed when the polyester-cotton yarn is dyed after weaving into a fabric, so that the fabric surface has a blank effect after printing and dyeing, which has a distinctive style and saves the cost of dyeing. Finished garments and other finished products are more fashionable. [0003] The production and processing method of conventional single-dyed polyester-cotton blended yarn is that polyester and cotton are made into raw sliver through cleaning and carding processes respectively, and the cotton raw sliver is made into combed cotton sliver through pre-merging and sliver-winding processes, and polyester raw sliver After the pre-drawing process, the pre-drawing is made, and then the combed cotton sliver and the polyester pre-drawin...
