Description

Spinning method and spinning device for soft skin-nourishing amino acid fibers

Technical Field

The invention belongs to the technical field of functional fiber preparation, and particularly relates to a spinning method and a spinning device for soft skin-nourishing amino acid fibers.

Background

Spinning is a synthetic spinning technology, which is a process for making silk yarns by melting a high molecular compound into a melt and then spraying the melt from fine holes of a spinneret.

At present, most of the existing spinning means adopt a metering pump to quantitatively and continuously spray melt out of a filament hole, and the melt is cooled and solidified in low-temperature water, solidification liquid or air after being sprayed out to generate nascent fiber. For example, common polyester fibers, polyamide fibers and amino acid fibers are spun by the method.

The plant protein amino acid fiber is natural and degradable, can resist ultraviolet rays and retain moisture and generate negative oxygen ions like green plants, has the effects of protecting skin and shaping body, and is a novel healthy and environment-friendly functional fiber. The morphological structure of the vegetable protein amino acid fiber is similar to that of the common pure viscose fiber, but the longitudinal groove is deeper, and the cross section is more obvious in a sawtooth shape; the hydrophilic polar groups in the plant protein extract improve the moisture absorption capacity of the plant protein amino acid fibers and have excellent bacteriostatic effect on staphylococcus aureus and candida albicans. In addition, the amino acid fiber can be mixed with cotton fiber, Tencel fiber, Modal fiber, bamboo fiber, wool, spun silk and the like according to a certain proportion, and the amino acid fiber series yarn is prepared by adopting a spinning process.

However, most of the existing spinning equipment can only spin for a specific type of fiber, when other types of fibers need to be produced, because the diameters of the fibers are different, and because the fiber fluid sprayed from the spray head needs to be rapidly cooled to ensure that the fibers are continuously formed into filaments, the flow rates of cold water required in the cooling process are different, a novel equipment needs to be developed, and the equipment can be adapted to the equipment with different diameters and cooling requirements.
