Embodiment 1

[0024] The production process of 19.7tex high-strength vortex spun viscose yarn, the production steps are as follows:

[0025] (1) Raw material selection:

[0026] Select viscose staple fibers with a fiber length of 38mm, a linear density of 1.33dtex, and a single fiber strength of 2.49cN / dtex as raw materials for eddy current spinning;

[0027] (2) Cleaning and carding process:

[0028] The staple fibers are passed through the cleaning and carding process to obtain fiber slivers. The specific steps are first to open, remove impurities, and mix the staple fibers evenly through the opening and cleaning unit, and then transport the fibers to the carding machine through the continuous feeding box. The machine combs the fiber bundles into a single fiber state to form fiber slivers. The process parameters are as follows: the raw sliver weight is 5.0g / m, the cylinder speed is 360r / min, the licker-in roller speed is 980r / min, and the doffer speed is 45r / min , the linear speed of th...

Abstract

The invention relates to a production process of a high-strength vortex spinning viscose yarn. The production process includes the following steps that viscose staple fiber is selected as a vortex spinning raw material; the staple fiber is processed by using a blowing-carding process to obtain fiber card slivers, specifically the staple fiber is subjected to opening, impurity removing and uniformmixing through opening and cleaning units firstly, the fiber is conveyed to a carding machine through a continuous feeding box, and fiber bundles are combed into a single fiber state by using the carding machine to form the fiber card slivers; the fiber card slivers are drawn through three paths for combination and drafting, so that the fiber is straight and parallel to obtain fiber drawn slivers;the fiber drawn slivers are sent to vortex spinning equipment for spinning, and spinning spindles are heated by using a high temperature compressed air heating method in the spinning process, so thatthe fiber drawn slivers after entering nozzles are spirally wrapped into yarns on the surfaces of the spinning spindles in a high temperature environment to form a cone yarn which is the high-strength vortex spinning viscose yarn. The production process has the advantages of less production process, large output and less labor, and the produced viscose yarn has the advantages of high strength, softness and comfort, good moisture absorption and the like.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a production process of high-strength vortex spun viscose yarn. Background technique [0002] At present, the production of vortex spinning yarn is mainly based on polyester and viscose raw materials, of which viscose accounts for a larger proportion. However, the viscose yarn has low strength and is easily damaged during the high-speed vortex spinning process, forming weak rings or hairiness, which affects the quality and production efficiency of the vortex spun viscose yarn. Therefore, improving the vortex spinning processing technology has great significance for improving the quality and efficiency of vortex spun viscose yarn. Contents of the invention [0003] Technical problem to be solved: In view of the existing vortex spinning process, the viscose yarn is easily damaged in the high-speed vortex spinning process, resulting in low strength and many hairiness. The presen...
