Problems solved by technology

However, because white factory silk is very expensive, it is difficult for consumers to afford it. At the same time, white factory silk and other biomass filaments such as viscose filaments have poor elastic recovery rate, and it is difficult to process them into elastic fibers by twisting. Development and application are limited

Embodiment 1

[0018] please see figure 1 , two polylactic acid filaments of the same specification and two biomass spun yarns 12 are given, and biomass spun yarns 12 are combined outside each polylactic acid filament 11, that is, polylactic acid filaments 11 and The biomass spun yarn 12 is wound in a helical shape and according to the required pitch to form a helical winding structure, and then two groups of core-spun yarns each consisting of a polylactic acid filament 11 and the biomass spun yarn 12 are helically wound to each other. twisted to form a yarn body 1. Wherein: the biomass spun yarn 12 is combined outside the polylactic acid filament 11. In this embodiment, the polylactic acid filament 11 is a polylactic acid multifilament, and the polylactic acid multifilament is composed of a plurality of polylactic acid monofilament bundles; the biomass spun yarn 12 is a bamboo charcoal fiber.

Embodiment 2

[0020] See figure 2 , two polylactic acid filaments 11 and a biomass spun yarn 12 made of hemp fiber are wound in a spiral shape to form a yarn body 1, and the rest are the same as the description of embodiment 1.

Embodiment 3

[0022] See image 3 A yarn body 1 is constructed by twisting a polylactic acid filament 11 and a biomass spun yarn 12 made of cashmere fibers in a helical shape. Among them, the polylactic acid filament 11 is polylactic acid elastic filament, and the polylactic acid elastic filament is made of polylactic acid filament multifilament through false twisting, and the rest are the same as the description of embodiment 1.

[0023] The technical solution provided by the present invention is not limited to the above-mentioned three embodiments, for example: two groups of polylactic acid filaments 11 of the same specifications can be respectively used as polylactic acid elastic filaments and the same specifications of cashmere fibers as biomass shorts The yarns 12 are mixed in a helically wound configuration. As another example, you can use figure 1 That is, the raw material of the biomass spun yarn 12 in Example 1 is replaced with a blended fiber of silk cotton and milk silk, a...

Abstract

The invention discloses a biopolymer fiber composite covering yarn structure and belongs to the technical field of textile yarns. The biopolymer fiber composite covering yarn structure comprises a yarn body, and is characterized in that: the yarn body is formed by combining one or two polylactide filaments and one or two biopolymer staple fiber yarns. The invention has the advantages that: because the yarn body is formed by combining the polylactide filaments and the biopolymer staple fiber yarns, the biopolymer fiber composite covering yarn structure has ideal softness, elasticity, affinity to skin, antibacterial permeability and an excellent environment-friendly effect.

Description

Technical field [0001] The invention belongs to the technical field of textile yarns, and specifically relates to a biomass fiber composite core-spun yarn structure. Background technique [0002] With the continuous improvement of people's living standards, the demand for green and environmentally friendly clothing has become a trend, especially underwear that is in direct contact with human skin. Most of the well-known types of core-spun yarns use chemical fiber filaments, such as polyester filaments, nylon filaments, and so on. The "core-spun yarn" recommended by China Patent Authorization Announcement No. CN201704474U uses nylon filament as the core filament, and is twisted by polyester filament and nylon filament. That is, the polyester filament is spirally wound on the nylon core filament, which has high strength and good elasticity. Advantages; "A composite elastic filament core-spun yarn fabric" provided by CN201952582U uses PTT / PET or non-elastic yarn as the elastic...
