Problems solved by technology

At present, flax elastic fabrics are generally woven by flax-coated elastic fiber filaments to form flax elastic core-spun yarns, but the flax fibers and elastic fiber filaments of this flax elastic yarn do not fully utilize the elastic fiber filaments after core-wrapping. Elastic recovery ability, in addition, the connection between flax fiber and elastic fiber filament is not very stable

Embodiment Construction

[0021] The content of the present invention will be further described in detail below.

[0022] A preparation method of high-performance linen core-spun yarn, characterized in that the steps are as follows:

[0023] S1, preparation of the outer layer roving: select raw flax with a splitting index greater than or equal to 250, and beat the raw flax into hemp; spray the hemp with an aqueous solution containing a humidifying agent for humidification; then use a forming machine to make flax strips, and Linen slivers, polyester fibers, and protein fibers are mixed and spun on a drawing frame in sequence to form outer rovings; the outer rovings are sequentially degummed with compound enzymes; moisturized for 18 to 36 hours; rovings are prepared through 4 draw frames; Gluease, lipase, xylanase, and cellulase are compounded according to the ratio of 3:2:1:1, and the degumming enzyme liquid is made through three-stage fermentation; the degumming is achieved by immersing the outer rovin...

Abstract

The invention discloses a preparation method of high-performance flax core-spun yarn. The preparation method comprises the following steps of: preparation of rough yarns at the outer layer, corn yarntreatment, core-spun treatment, dissolution treatment and water bath dissolution; according to the preparation method disclosed by the invention, spandex fibers and T-400 fibers are twisted mutually;spandex fibers and the T-400 fibers are each of a high-elasticity fiber material; when the two types of high-elasticity fiber yarns are mutually twisted, the formed twisting elasticity can produce twotypes of elastic restoring force; the first one is the elastic restoring force generated when the elastic fibers are bent; the second one is the elastic restoring force generated when the two types elastic fibers are to be radially separated; thus the elasticity of the elastic twisted fibers of the high-performance flax core-spun yarn disclosed by the invention is enhanced; and the elastic restoring force of the high-performance flax core-spun yarn disclosed by the invention is increased.

Description

technical field [0001] The invention relates to a preparation method of high-performance linen core-spun yarn. Background technique [0002] Linen products have a long history and enjoy a high reputation in the world. Even today when silk, pure cotton, wool, man-made fibers and other fabrics are very developed, linen fabrics still occupy an irreplaceable noble position. Flax's natural air permeability, hygroscopicity, freshness and drainage make it a freely breathing textile. At room temperature, it can reduce the temperature of the human body's room by 4-8°C, and it is called "natural air conditioner". At present, flax elastic fabrics are generally woven by flax-coated elastic fiber filaments to form flax elastic core-spun yarns, but the flax fibers and elastic fiber filaments of this flax elastic yarn do not fully utilize the elastic fiber filaments after core-wrapping. Elastic recovery ability, in addition, the connection between the flax fiber and the elastic fiber fila...
