Description

Technical Field

[0001] This utility model relates to the field of eco-friendly fabric technology, and in particular to an ultra-soft polylactic acid eco-friendly fabric. Background Technology

[0002] Eco-friendly fabrics refer to textile products that are harmless to human health and environmentally friendly. They are made from raw materials that are harmless or have minimal harm to the environment, and the use of harmful substances such as harmful dyes, methanol, and heavy metals is strictly controlled. The main purpose of eco-friendly fabrics is to reduce negative impacts on the environment while ensuring the health and safety of users.

[0003] Patent documents disclose an environmentally friendly antibacterial and deodorizing clothing fabric, comprising a fabric body, which includes a surface elastic layer, an odor-neutralizing layer, an antibacterial layer, and an inner elastic layer, and is formed by sewing the surface elastic layer, odor-neutralizing layer, antibacterial layer, and inner elastic layer sequentially from top to bottom. The odor-neutralizing layer includes an equal number of bamboo fiber warp yarns and bamboo fiber weft yarns, and is formed by interweaving several bamboo fiber warp yarns and bamboo fiber weft yarns. The antibacterial layer includes an equal number of kapok fiber yarns and Tencel fiber yarns, and is formed by interweaving several kapok fiber yarns and Tencel fiber yarns. The surface elastic layer is made of several spandex yarns, and the inner elastic layer is made of several polyester yarns. The odor-neutralizing layer has a plain weave structure, and the antibacterial layer has a satin weave structure. This utility model has a reasonable structure and has the advantages of good antibacterial and antimicrobial effects, good deodorizing performance, and good elasticity.

[0004] However, after disposal, the stacking of multiple layers of fabric significantly slows down the degradation rate of the inner layer, which is detrimental to the health of the natural ecosystem. Therefore, it is necessary to improve this structure to overcome the aforementioned drawbacks. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-soft polylactic acid eco-friendly fabric to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An ultra-soft polylactic acid (PLA) eco-fabric includes an upper biodegradable layer, a breathable layer, a lower biodegradable layer, and PLA yarn. The breathable layer is disposed inside the upper biodegradable layer, and the lower biodegradable layer is disposed inside the breathable layer. The breathable layer and the upper biodegradable layer are connected by PLA yarn, which passes sequentially through the upper biodegradable layer and the breathable layer. The PLA yarn also penetrates the upper biodegradable layer and the breathable layer. The breathable layer and the lower biodegradable layer are connected by PLA yarn, which passes sequentially through the breathable layer and the lower biodegradable layer. The PLA yarn also penetrates the breathable layer and the lower biodegradable layer.

[0008] The present invention is further provided that the breathable layer is provided with breathable holes, and a set of breathable holes are provided. The breathable holes penetrate the breathable layer, thereby increasing the breathability of the breathable layer and the area of ​​contact with air.

[0009] The present invention is further configured such that the upper biodegradable layer is made of polylactic acid fabric.

[0010] The present invention is further characterized in that the breathable layer is made of cotton fiber.

[0011] The present invention is further configured such that the lower biodegradable layer is made of polylactic acid fabric.

[0012] The present invention is further configured such that the polylactic acid yarn connects each fabric layer along the transverse and longitudinal directions, thereby ensuring the connection strength between each fabric layer.

[0013] The advantages of this utility model are:

[0014] 1. This utility model connects the various fabric layers by setting polylactic acid yarn. When the fabric is no longer used, the polylactic acid yarn, due to its fineness, will break first due to degradation, causing the various fabric layers to decompose. This allows the inner breathable layer to come into contact with the outside world more quickly and degrade, greatly increasing the overall degradation speed of the fabric and effectively preventing damage to the environment.

[0015] 2. By setting breathable holes in the breathable layer, this utility model greatly increases the breathability of the fabric during use, ensuring that the fabric stays dry. When the fabric degrades, the breathable holes allow the breathable layer to degrade directly from the inside, effectively accelerating the degradation rate of the fabric.

[0016] 3. This utility model increases the connection strength between various fabrics by connecting polylactic acid yarns in both the horizontal and vertical directions. Attached Figure Description
