Problems solved by technology

[0003] The moisture absorption effect of the fabric is usually determined by the yarn characteristics of the fabric. After the surface of the fabric is coated with glue, a waterproof layer will be formed, making the yarn unable to breathe freely, and the effect of moisture absorption and ventilation is greatly reduced, which limits the scope of application.

Embodiment 1

[0020] A production process of moisture-absorbing and breathable elastic yarn, comprising the following steps:

[0021] The production of the base line, the elastic fiber filament is used as the core yarn, the moisture-absorbing short fiber is outsourced, twisted together and spun into the base line, and then the first winding is carried out. The elastic fiber filament is spandex filament, and the Hygroscopic short fiber is cotton fiber;

[0022] Dyeing, dyeing the strands and then drying;

[0023] Apply glue, unwind the blank line for the first time, apply elastic glue to the surface of the blank line in the first unwinding, and form a protective layer after the elastic glue dries, then perform the second winding, control the winding and unwinding speed, In order to maintain the natural state of the blank line, not curled, but not too tight, the rubber box is used to store the elastic glue, and the guide wheel installed in the plastic box guides the blank line into the plast...

Embodiment 2

[0026] A production process of moisture-absorbing and breathable elastic yarn, comprising the following steps:

[0027] The production of the base line uses the elastic fiber filament as the core yarn, outsourcing the hygroscopic staple fiber, twisting together and spinning into the base line, and then performing the first winding. The elastic fiber filament is polyester elastic fiber filament. The hygroscopic short fiber is bamboo fiber;

[0028] Apply glue, unwind the billet line for the first time, apply a layer of elastic glue to the surface of the billet line in the first unwinding, and form a protective layer after the elastic glue is dried. The elastic glue is a silicone high-elastic coating Glue, carry out the second winding, control the speed of winding and unwinding, so as to maintain the natural state of the billet line, not curled, but not too tight, use the rubber box to hold the elastic glue, and pass through in the process of winding and unwinding The guide whe...

Abstract

The invention discloses a moisture-absorbing breathable elastic yarn production process. The process includes steps: gray yarn production, to be specific, taking elastic fiber filaments as core filaments, externally wrapping with moisture-absorbing short fibers, jointly twisting to make gray yarns by spinning, and performing winding for the first time; gluing, to be specific, unwinding the gray yarns for the first time, coating surfaces of the gray yarns with elastic glue in unwinding for the first time, and after the elastic glue is dry and forms protective layers, winding for the second time; needling, to be specific, unwinding the gray yarns for the second time, and after the surfaces of the protective layers is pierced by a needling wheel, winding for the third time to obtain a finished product. The moisture-absorbing breathable elastic yarn production process has advantages that the surfaces of the gray yarns are coated with organic silicon high-elastic coating glue to serve as flexible protective layers to keep elasticity of the gray yarns, washing resistance and oil dirt resistance of the yarns are improved, and by the needling wheel for forming fine pores in the protectivelayers, stability of the protective layers is undamaged, and excellent moisture absorbing effects and breathability are achieved.

Description

technical field [0001] The invention relates to the technical field of yarn production, in particular to a production process of moisture-absorbing and air-permeable elastic yarn. Background technique [0002] In order to improve the washing resistance and oil stain resistance of the fabric, a waterproof coating can be applied to the surface of the fabric. At the same time, by choosing an elastic waterproof coating glue, it can not only realize the waterproof of the fabric, but also maintain the original elasticity of the fabric. [0003] The moisture absorption effect of the fabric is usually determined by the yarn characteristics of the fabric. After the surface of the fabric is coated with glue, a waterproof layer will be formed, making the yarn unable to breathe freely. The moisture absorption and breathability effect is greatly reduced, which limits the scope of application. Contents of the invention [0004] The purpose of the present invention is to provide a produ...
