Embodiment 1

[0039] A kind of technical method of dry-spinning cotton-linen blended spinning, is prepared by the following steps:

[0040] (1) Combing hemp strips: Bleaching and degumming the raw hemp, kneading the hemp once, maintaining health for 3 days (according to 100kg flax mixed with 3kg health-care solution + 11kg water), kneading the hemp twice, cutting to 110mm, and then loosening three times, The raw hemp is spun into carded hemp sliver with a carding machine, and the determined quantity is 28g / 5m, and the health-preserving liquid is commercially available;

[0041] (2) Pure blending of hemp strips: combine hemp strips and hemp strips, and formulate a quantitative value of 22g / 5m to make the quantitative stability, optimize the quantitative ratio for the blending ratio, control the total draft ratio to 6 times, and the draft ratio in the rear area is 1.5 times, the drawing speed is 200m / min;

[0042] (3) Mixing and merging: the hemp slivers after pure merging are mixed with pur...

Abstract

The invention relates to the technical field of spinning, in particular to a process method for dry spinning of cotton and linen blended yarn. The process method for dry spinning of the cotton and linen blended yarn comprises the steps that firstly, a carding machine is used for spinning raw linen into linen slivers, pure drawing is conducted on the linen slivers, then the purely drawn linen slivers and combed pure cotton slivers are subjected to mixed drawing, and finally roving, spinning and spooling are conducted in sequence. The process method for dry spinning of the cotton and linen blended yarn solves the problems of inaccurate linen blending ratio and numerous linen skins and silks, reduces the burling and defective cloth conditions fed back by subsequent procedures, and can spin varieties of high-proportion linen and high-count linen, so that the linen variety has the better linen feeling; the used raw linen is relatively low in cost; and meanwhile, bulk products can be smoothly produced.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a process for dry spinning cotton and linen blended yarn. Background technique [0002] Cotton and linen blend is a blend of cotton fiber and hemp fiber. Cotton and linen blended fabric has both the softness and comfort of cotton and the cool and cooling effect of linen. Therefore, the development momentum of the cotton and linen products industry is getting better and better. The traditional dry-spinning cotton and linen blended spinning process adopts the blending process. The production process is as follows: flax fiber + banquet cotton→wrapping, secondary packaging→rolling→combing Cotton → head and end → end and roving → spun yarn → winding, due to the short, thick and hard characteristics of hemp fiber in the cleaning and carding process, the rate of nodding is high, which affects the proportion of flax in the yarn, and the high proportion of spinning Linen is very difficu...
