Description

Technical Field

[0001] This utility model relates to a curtain fabric, specifically a light-blocking and heat-insulating curtain fabric. Background Technology

[0002] Traditional cotton and linen curtains are common types of curtains. Their relatively loose fiber structure has significant drawbacks in terms of light blocking. For example, sunlight can easily penetrate the fabric's gaps into the room, resulting in relatively bright rooms even during the day, even with the curtains drawn. This is unsuitable for sleeping environments or those requiring dim lighting, such as for naps or watching videos in the bedroom. In terms of heat insulation, ordinary fabric curtains have limited performance. For instance, in summer, solar radiation can penetrate the curtains, raising the indoor temperature. Therefore, it is necessary to provide a light-blocking and heat-insulating curtain fabric. Utility Model Content

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the sound-absorbing yarn includes a core yarn and an outer yarn, the outer yarn covers the outside of the core yarn, the core yarn is basalt fiber filament, and the outer yarn is polyester-cotton blended yarn.

[0010] The beneficial effects of this utility model are as follows: Based on the light-blocking and heat-insulating curtain fabric of this utility model, the light-blocking layer is made of black, matte, UV-resistant polyester elastic yarn of 300D / 288F. It achieves good light-blocking performance by utilizing the characteristics of thick yarn, dark color, and high warp and weft density. The heat-insulating layer is made of polyimide fiber yarn, which has good heat insulation effect. The antibacterial and mildew-proof layer has not only good antibacterial and mildew-proof effect, but also has the function of removing formaldehyde.

[0012] In the diagram: 1-shielding layer, 2-heat insulation layer, 3-antibacterial and mildew-proof layer, 4-sound-absorbing layer. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Combination Figure 1 This embodiment provides a detailed description of a light-blocking and heat-insulating curtain fabric, comprising: a light-blocking layer 1, a heat-insulating layer 2, an antibacterial and mildew-proof layer 3, and a sound-absorbing layer 4 arranged sequentially; the light-blocking layer 1, the heat-insulating layer 2, the antibacterial and mildew-proof layer 3, and the sound-absorbing layer 4 are connected by quilting; the light-blocking layer 1 is woven from black, matte, UV-resistant polyester elastic yarn; the heat-insulating layer 2 is woven from heat-insulating yarn; the antibacterial and mildew-proof layer 3 is woven from antibacterial and mildew-proof yarn; and the sound-absorbing layer 4 is woven from sound-absorbing yarn.

[0015] Furthermore, the specifications of the black, fully matte, UV-resistant polyester elastic yarn are 300D / 288F.

[0016] Furthermore, the warp density of the light-blocking layer 1 is 1260 threads / 10cm, and the weft density is 250 threads / 10cm. The light-blocking performance of the fabric is directly related to the gap between the warp and weft threads. Increasing the warp and weft density reduces the gap, thus reducing the intensity of light transmission through the fabric gaps and achieving a good light-blocking effect. Simultaneously, thicker yarns result in greater fabric thickness, leading to more light absorption and better light-blocking performance; darker fabric colors result in lower light transmittance and better light-blocking performance. Therefore, the light-blocking layer 1, woven from 300D / 288F black matte UV-resistant polyester elastic yarn, exhibits excellent light-blocking performance.

[0017] Furthermore, the heat-insulating yarn is a polyimide fiber yarn. Polyimide fiber is a high-performance aromatic heterocyclic polymer with a limiting oxygen index as high as 38%. It carbonizes without dripping when exposed to high temperature open flame, is self-extinguishing after being removed from the flame, and is non-toxic. This ensures that the fabric has good mechanical properties and dimensional stability in high and low temperature environments, and also has good heat oxidation resistance, corrosion resistance, and UV resistance. The heat insulation layer 2 woven from it has good heat insulation performance.

[0018] Furthermore, the antibacterial and antifungal yarn is a multifunctional viscose fiber yarn that is antibacterial, antifungal, and formaldehyde-removing. This multifunctional viscose fiber is prepared by blending and spinning a suspension of plant-based Chinese medicinal herbs, including wild chrysanthemum extract, coptis extract, and sweet orange essential oil microcapsules, with viscose spinning solution. Coptis extract, wild chrysanthemum extract, and sweet orange essential oil possess excellent antibacterial and antifungal properties, while zeolite micropowder exhibits good adsorption properties, making it an effective base material for formaldehyde adsorption. The multifunctional viscose fiber exhibits a 97.04% inhibition rate against Staphylococcus aureus, achieves a level 0 antifungal function, and a formaldehyde removal rate of 60.88%. After 20 washes, the inhibition rate against Staphylococcus aureus remains at 84.87%, and the antifungal function still reaches level 0. After 10 washes, the formaldehyde removal rate reaches 65.45%. After the fiber is nearly saturated with formaldehyde, further washing allows the formaldehyde in the fiber to dissolve in water, enabling repeated formaldehyde absorption.

[0019] Furthermore, the sound-absorbing yarn comprises a core filament and an outer covering yarn, with the outer covering yarn covering the outside of the core filament. The core filament is basalt fiber filament, and the outer covering yarn is a polyester-cotton blended yarn. Basalt fiber is naturally derived, biodegradable, and recyclable. It possesses numerous excellent properties, including high sound absorption coefficient, high strength, high modulus, fire retardancy, and resistance to ultraviolet light. It also exhibits good thermal insulation and sound insulation performance, making it widely used in noise reduction. Specifically, the polyester-cotton blended yarn is a 65 / 35 polyester-cotton blended yarn, which, as the outer covering yarn, covers the basalt fiber filament, mitigating issues such as snagging and breakage during the spinning and weaving process.

[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.
