Description

Technical Field

[0001] This utility model relates to a polylactic acid knitted fabric, belonging to the field of knitted fabric technology. Background Technology

[0002] With the increasing severity of global climate change and the growing acceptance of sustainable development concepts, environmental protection and energy conservation have become crucial directions for the future development of the textile industry. Especially with consumers' increasing focus on green and healthy lifestyles, the textile industry is facing unprecedented pressure and opportunities for transformation. The research and application of low-carbon and environmentally friendly materials have become key to promoting the industry's sustainable development. At the same time, the comfort, functionality, and innovation of textile products are increasingly favored by consumers. Knitted fabrics, in particular, due to their unique softness, breathability, and elasticity, have been widely used in clothing, home furnishings, sportswear, and medical applications.

[0003] However, traditional textile fabric production consumes significant resources and generates substantial waste, severely impacting the environment. Especially with increasing global emphasis on carbon emissions and resource consumption, the industry urgently needs to develop more environmentally friendly and low-carbon textile materials through technological innovation. By adopting renewable materials, environmentally friendly dyeing technologies, and energy-saving production processes, the textile industry can drive a green transformation, reducing resource consumption and carbon emissions, and enhancing the environmental friendliness and sustainability of textiles. The core technology of low-carbon and environmentally friendly knitted fabrics lies in the green selection of materials and innovative processes. By using natural fibers, biodegradable fibers, and recycled waste textiles, we can effectively reduce the carbon footprint of the production process. Environmentally friendly and sustainable fabrics not only meet the modern consumer's increasing demands for comfort and personalization but also bring enormous market potential and development opportunities to the textile industry.

[0004] Polylactic acid (PLA) fiber, as a major raw material for fabrics, has significant low-carbon and environmentally friendly characteristics. It not only reduces carbon emissions during the production process but also effectively reduces the burden on the environment. The challenge lies in developing a PLA knitted fabric that, while ensuring comfort, softness, and breathability, incorporates high-performance environmentally friendly elements. This fabric should meet the modern consumer demand for comfort and style while aligning with the trend of green and sustainable development. Utility Model Content

[0005] The purpose of this invention is to provide a polylactic acid knitted fabric that is environmentally friendly, biodegradable, and moisture-wicking.

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0007] This utility model relates to a polylactic acid knitted fabric, which includes a polylactic acid fabric base layer;

[0008] The polylactic acid fabric base layer is a double-knitted fabric consisting of an outer layer and an inner layer. The yarn used in the inner layer is polylactic acid compact Sirospun yarn, and the outer layer is made of polylactic acid composite filament.

[0009] The polylactic acid fibers used in the polylactic acid compact siro-spun yarn have a cross-shaped or Y-shaped cross section.

[0010] The polylactic acid composite filament comprises parallel polylactic acid filaments and regenerated cellulose fiber yarns; the fineness of the polylactic acid filaments is 72D / 144-288F; the cross-section of the regenerated cellulose fiber is flat.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the regenerated cellulose yarn is Viloft fiber yarn with a yarn fineness of 14.5 tex.

[0012] The beneficial effects of this utility model are as follows: The polylactic acid knitted fabric involved in this utility model is a double-sided knitted fabric. One side uses a compact polylactic acid Sirospun yarn made of polyester yarn with an irregular cross-section, which has a moisture-wicking effect; the other side uses a regenerated cellulose fiber yarn with a good moisture absorption effect, thus enabling the knitted fabric to have a moisture-wicking and perspiration-absorbing effect. Furthermore, both the polylactic acid and the regenerated cellulose fiber used are biodegradable and environmentally friendly. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of the polylactic acid knitted fabric involved in Example 1. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] Combination Figure 1 This embodiment will be described in detail below. The polylactic acid (PLA) knitted fabric involved in this embodiment includes a PLA fabric base layer 1; the PLA fabric base layer 1 is a double-sided knitted fabric comprising a surface layer 11 and an inner layer 12. The yarn used in the inner layer 12 is PLA compact Sirospun yarn, and the surface layer 11 is made of PLA composite filament.

[0017] The polylactic acid (PLA) fibers used in the compact Sirospun yarn have a cross-shaped or Y-shaped cross-section; in this embodiment, a cross-shaped cross-section is chosen. The surface of the cross-shaped or Y-shaped PLA fibers has grooves along its length, and due to the wicking effect, the compact Sirospun yarn has a moisture-wicking effect. Furthermore, PLA is polylactide, which has poor moisture absorption, thus preventing moisture storage in the inner layer.

[0018] The polylactic acid composite filament comprises parallel polylactic acid filaments and regenerated cellulose fiber yarns; the fineness of the polylactic acid filaments is 72D / 144-288F, and in this embodiment, 72D / 144F is selected; the cross-section of the regenerated cellulose fiber is flat. The regenerated cellulose fiber has good moisture absorption properties, allowing the surface layer 11 to absorb moisture, which, in conjunction with the inner layer 12, provides a moisture-wicking effect.

[0019] Furthermore, the regenerated cellulose yarn is Viloft fiber yarn with a yarn fineness of 14.5 tex. Viloft fiber is produced by Acordis, a British company, using environmentally friendly processes to extract cellulose from artificially cultivated eucalyptus pulp.

[0020] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
