[0002] As people's living standards continue to improve, public attention to sleep quality and overall quality of life is constantly rising. Bedding, as a key factor affecting sleep quality, is receiving increasing attention for its performance, comfort, and environmental friendliness. Traditional silk quilts, with their softness, comfort, warmth, breathability, skin-friendly properties, and antibacterial effects, have long been favored by consumers and are an important part of the high-end bedding market. However, during use and disposal, traditional silk quilt covers are typically difficult to degrade in the natural environment. Once discarded, they often take a long time to decompose, which not only occupies a large amount of land resources but also pollutes soil and water bodies. Therefore, it is necessary to provide a biodegradable silk quilt. Utility Model Content

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

[0015] Combination Figure 1-2 This embodiment provides a detailed description of a biodegradable silk quilt, comprising: a quilt core 1 and a quilt cover 2, wherein the quilt core 1 is disposed inside the quilt cover 2, and the quilt core 1 and the quilt cover 2 are fixed together by quilting; the quilt core 1 is a silk fiber layer; the quilt cover 2 comprises a skin-friendly layer 3, an antibacterial layer 4, and a thermal insulation layer 5 arranged sequentially; the skin-friendly layer 3 is woven from biodegradable skin-friendly yarn; the antibacterial layer 4 is woven from biodegradable antibacterial yarn; and the thermal insulation layer 5 is woven from biodegradable thermal insulation yarn.

[0016] Furthermore, the biodegradable skin-friendly yarn is a biodegradable polylactic acid (PLA) twisted filament yarn. Biodegradable PLA twisted filament yarn is prepared from biodegradable PLA filaments through twisting and heat setting. PLA filament is a synthetic fiber made from recycled starch raw materials, such as corn and wheat, through fermentation to produce lactic acid, which is then polymerized and spun. It features sustainable raw material sourcing and biodegradable products. PLA filament has excellent wearing performance, combining the environmental friendliness, pollution-free nature, and comfortable wear of recycled fibers with the high elasticity, high strength, and high breaking strength of synthetic fibers. Biodegradable PLA twisted filament yarn has a smooth surface and good luster. The yarn has a plied structure, which improves the bundled properties and abrasion resistance of the filament yarn, facilitating subsequent weaving processes. The fabric also has excellent drape and smoothness, a fluffy feel, and is non-sticky and non-irritating to the skin, exhibiting good skin-friendliness.

[0017] Furthermore, the biodegradable antibacterial yarn is polylactic acid-thymol antibacterial fiber yarn. Polylactic acid-thymol antibacterial fiber is prepared by uniformly mixing polylactic acid, which has good biodegradability, with the natural antibacterial agent thymol using a temperature-controlled blending device, followed by melt spinning. Polylactic acid has excellent biodegradability; under natural conditions, it can be completely degraded into carbon dioxide and water, re-entering the ecosystem cycle. The substances produced during its degradation are also normal metabolic products of the human body and are harmless. Thymol, also known as thymol, is extracted from plants of the genus Thymus and has excellent antibacterial and broad-spectrum antibacterial properties. It exhibits excellent antibacterial effects against Escherichia coli and Staphylococcus aureus. Antibacterial fibers prepared using polylactic acid as the base material and thymol as the antibacterial component not only have excellent antibacterial effects and mechanical properties but are also biodegradable after use.

[0018] Furthermore, the biodegradable insulating yarn is made by twisting kapok fiber yarn and cotton fiber yarn together. Kapok fiber has high hollowness, is ultra-lightweight, has a low thermal conductivity, and is fine, making it an excellent insulating material. In addition, the grooves and unevenness on the cell wall surface provide good moisture absorption and release. Cotton fiber is a porous fiber with many tiny pores inside. These pores can trap a large amount of air, and since air is a poor conductor of heat, it effectively prevents heat conduction, thus providing insulation. Furthermore, cotton fiber has a natural crimp, which increases the gaps between fibers, allowing more air to be trapped, forming an air layer. This air layer slows down heat loss and improves insulation performance. Both kapok and cotton fibers are natural fibers and are biodegradable.

[0019] Furthermore, the skin-friendly layer 3, the antibacterial layer 4, and the thermal insulation layer 5 are connected by quilting.

[0020] Furthermore, the weight of the silk fiber layer is 300-450 g / m². Specifically, in this embodiment, the weight of the silk fiber layer is 400 g / m², suitable for use in spring and autumn.

[0021] 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.
