Embodiment 1

[0040] A preparation method for hemp viscose vortex spinning yarn, comprising the following steps:

[0041] The hemp fiber is mixed evenly with the viscose fiber after the humidity control treatment in the Trützschler Qinggang BO-A cotton grabbing machine and the MX-U6 multi-bin cotton mixing machine, and then the CL-C1 cotton cleaning machine is opened and cleaned, and the TC -5 carding machine carding, FA288 combing machine combing, three-way merging process (including FA320A-G60 head draw frame, TD 8 second-line draw frame, FA322 draw frame autolevelling), MVS .NO.870 type vortex spinning machine spinning to obtain the hemp viscose vortex spinning yarn.

[0042] Raw material selection and pretreatment: In order to do a good job in trial spinning, select raw materials with better performance: fiber fineness of 0.35tex, average fiber length of 35mm, average linear density of 0.32-0.34tex, breaking strength >7.6cN / tex, elongation The elongation rate is 7.6%, and the ultra-long ...

Embodiment 2

[0057] A method for preparing a hemp viscose vortex spun knitted fabric produced by using the hemp viscose vortex spun yarn, comprising the following steps: the hemp viscose vortex spun yarn sequentially passes through doubling, rewinding, weaving, and sleeve opening , flat car, hand sewing, washing, drying, ironing, packaging, and storage to obtain the hemp viscose vortex spun knitted fabric. Density: 32 / 10cm; Longitudinal density: 22.3 / 10cm, needle size: 7G, knitted on a computerized flat knitting machine, yarn: 11 S / 4 strands, weight: 296 g / m2.

[0058] The hemp viscose eddy current spinning knitted fabric of the present invention is woven by a computerized flat knitting machine, and is mainly optimized for the yarn tension of the computerized flat knitting machine. In the sheet process, a new type of yarn storage device is used to strictly control its tension, so as to avoid problems such as yarn breakage and defects caused by uneven yarn gravity.

Abstract

The invention discloses a hemp viscose vortex spinning yarn and application thereof. The yarn is prepared from, by mass, 30-70% of hemp fiber and 30-70% of viscose fiber. A hemp viscose vortex spinning knitted fabric produced with the hemp viscose vortex spinning yarn is a single-sided plain-stitch fabric weave, has the transverse density of (30-35) / 10cm, the longitudinal density of (20-25) / 10cm,the needle number of 7G, the plied yarn of 11S / 4 and the gram weight of 290-300 g / cm<2> and is woven on a computerized flat knitting machine. The hemp viscose vortex spinning yarn is spun through jetvortex spinning, the process is short, and the environment protection and energy conservation are achieved; the amount of wax on the yarn is increased during weaving, dynamic tension control is adopted, and the total tension is reduced properly.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a hemp viscose vortex spun yarn and its application. Background technique [0002] At present, the focus of competition in the international textile market is to create new popular designs and promote high-grade and high-grade air-spun fabrics. Traditional air-spinning equipment uses airflow to complete fiber delivery and twisting. Its process flow is short and its structure is simple. , High output, but due to reasons such as raw material adaptability, it is gradually eliminated. Subsequently, countries such as Japan and Germany successively developed new vortex spinning equipment, which further improved the drafting system, suitable fibers, output, quality, degree of automation and online detection. When spinning polyester / cotton and purified fibers, Its products have good adaptability and have obvious competitive advantages in similar spinning equipment. The rapid de...
