Description

Technical Field

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

[0002] Polylactic acid (PLA) fiber, made from starch-containing raw materials such as corn and wheat through fermentation to convert them into lactic acid, followed by polymerization and spinning, not only possesses excellent physical and wearability properties but also exhibits biodegradability. It is a novel, environmentally friendly fiber that can be completely recycled naturally and is currently the only synthetic fiber that does not rely on petroleum resources. PLA fiber has unique physicochemical properties and exists in both short and long filament forms. It can be used to weave various woven and non-woven products. Textiles typically include underwear, casual wear, and bedding. Fabrics made from PLA are soft to the touch, shape-stable, and possess good crimp and elasticity. While silk, as a natural protein fiber, has excellent skin-friendly properties, it is expensive. PLA, being biodegradable and skin-friendly, can be used to partially replace silk in fabric production, thus reducing fabric costs. However, PLA fiber has poor water absorption; therefore, developing a PLA-silk woven fabric with moisture-wicking properties is a key challenge. Utility Model Content

[0003] The purpose of this invention is to provide a polylactic acid silk woven fabric with good moisture absorption and wicking properties as well as skin-friendly properties.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] The present invention relates to a polylactic acid silk woven fabric, comprising a composite outer fabric and an inner fabric.

[0006] The inner fabric is made of polylactic acid filament / silk composite yarn interwoven with a perforated structure. The polylactic acid filament / silk composite yarn includes polylactic acid filaments and silk yarns twisted together. The cross-section of the monofilaments in the polylactic acid filaments is cross-shaped or Y-shaped.

[0007] The outer fabric is made of wear-resistant and UV-resistant yarns and cellulose fiber yarns as warp and weft yarns, interwoven in a plain or twill weave.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the fineness of the polylactic acid filament is 40-75 dtex / 36-48F.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the specifications of the silk yarn are 4 / 22.2 / 24.4 dtex.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant and UV-resistant yarn includes a core yarn and a covering fiber layer, wherein the core yarn is flax fiber yarn or bamboo fiber yarn; and the covering fiber layer is biodegradable nylon fiber.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the cellulose fiber yarn is Proviscose fiber yarn, cotton fiber yarn, modal fiber yarn or viscose fiber yarn.

[0012] Based on the above solution and as a preferred embodiment of the above solution: a waterproof and breathable membrane is provided between the outer fabric and the inner fabric.

[0013] The beneficial effects of this utility model are as follows: The polylactic acid silk woven fabric involved in this utility model uses twisted polylactic acid filaments and silk yarns for the inner layer, and the polylactic acid fibers have an irregular cross-section, which has a good sweat-wicking effect. The outer layer uses cellulose fiber yarns, which have a good moisture absorption effect, thus keeping the inner layer dry and improving wearing comfort. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] Combination Figure 1 and Figure 2This embodiment provides a detailed description. The polylactic acid (PLA) silk woven fabric involved in this embodiment includes a surface fabric 1 and an inner fabric 2, which are composited by a hot-melt adhesive web. The inner fabric 2 is woven from PLA filament / silk composite yarns in a perforated weave, wherein the PLA filament / silk composite yarns include PLA filaments and silk yarns twisted together; the cross-section of the monofilaments in the PLA filaments is cross-shaped or Y-shaped. The surface fabric 1 is woven from abrasion-resistant and UV-resistant yarns and cellulose fiber yarns as warp and weft yarns in a plain or twill weave.

[0021] The inner fabric 2 uses a perforated structure, which reduces the amount of fabric in contact with the skin. Even if the inner fabric 2 absorbs moisture, it will not completely stick to the skin surface, thus improving wearing comfort. Furthermore, the perforated structure increases the breathability of the inner fabric 2, thereby improving the overall breathability of the polylactic acid silk woven fabric.

[0022] Each monofilament in the polylactic acid filament has an irregular cross-section and grooves on its surface, giving it excellent moisture-wicking properties due to the wicking effect. The outer fabric 1 uses highly absorbent cellulose fibers, which can absorb sweat moisture from the inner fabric 2 and transfer it to the outer fabric 1. The outer fabric 1 then carries away the moisture due to airflow, achieving a quick-drying effect and improving the wearing comfort of garments made from this fabric.

[0023] Furthermore, the polylactic acid filament has a fineness of 40-75 dtex / 36-48F, specifically 75 dtex and 48F selected in this embodiment. The silk yarn has a specification of 4 / 22.2 / 24.4 dtex.

[0024] Furthermore, the wear-resistant and UV-resistant yarn includes a core yarn 11 and a covering fiber layer 12. The core yarn 11 is either flax fiber yarn or bamboo fiber yarn; the covering fiber layer 12 is biodegradable nylon fiber. In this embodiment, the core yarn is selected as bamboo fiber yarn. Bamboo fiber is made from bamboo and has antibacterial, deodorizing, and UV-resistant properties. It has excellent moisture absorption and breathability, making it suitable for summer wear, and is environmentally friendly, being made from renewable resources. The UV resistance of bamboo fiber is 41.7 times that of cotton, effectively blocking UV damage to the skin.

[0025] Furthermore, the cellulose fiber yarn is Proviscose fiber yarn, cotton fiber yarn, modal fiber yarn, or viscose fiber yarn. In this embodiment, 45-count Proviscose fiber yarn is selected. Proviscose fiber is a perfect combination of Lenzing Tencel and Lenzing viscose, blended in a 30 / 70 ratio. Its Chinese name is "Tian Shu". It is produced and supplied by Nantong Dasheng Group under authorization from Lenzing. It is 100% naturally biodegradable, eco-friendly, and its texture is between Tencel and viscose, combining the excellent characteristics of both. Its products are flexible, smooth, drape well, absorbent, and breathable.

The polylactic acid silk woven fabric involved in this embodiment differs from that in Embodiment 1 in that a waterproof and breathable membrane 3 is provided between the outer fabric 1 and the inner fabric 2. The waterproof and breathable membrane 3 is either a PTFE microporous membrane or a TPU microporous membrane; in this embodiment, a TPU microporous membrane is selected.

[0028] 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.
