The quality of indoor air is directly related to human health. Formaldehyde, as the main indoor air pollutant gas, can cause nasopharyngeal cancer, leukemia, etc. Therefore, it is necessary to develop a stain-resistant polyester fabric with formaldehyde removal function for the production of curtain fabrics in combination with the current development trend of home textile decorative fabrics.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic structural diagram of the stain-resistant polyester fabric involved in the utility model;

[0011] In the figure: 1-fouling resistant layer, 2-antibacterial layer, 3-light shielding layer, 4-formaldehyde removal layer. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Combination Figure 1 This embodiment is described in detail. A stain-resistant polyester fabric includes: a stain-resistant layer 1, an antibacterial layer 2, a light-shielding layer 3 and a formaldehyde removal layer 4 which are compounded in sequence; the stain-resistant layer 1 is formed by interweaving antistatic yarn as warp yarn and Cylis biodegradable fiber yarn as weft yarn; the antistatic yarn and the Cylis biodegradable fiber yarn are attached with a three-proof finishing agent on their surfaces; the light-shielding layer 3 is interweaved with black full-dull polyester fiber filaments; the formaldehyde removal layer 4 is formed by interweaving polyester network yarn as warp yarn and photocatalyst fiber yarn as weft yarn. The stain-resistant layer 1, the antibacterial layer 2, the light-shielding layer 3 and the formaldehyde removal layer 4 are compounded by a mesh hot melt adhesive.

[0014] Furthermore, the stain-resistant layer 1 is a three-up, two-down, one-up, two-down warp twill weave. The floats of this weave structure are longer than those of the plain weave, and the fabric is relatively flat, not easy to hide dirt, and it is also easier to remove stains when washing.

[0015] Specifically, the antistatic yarn is a graphene-modified antistatic polyester fiber yarn. Graphene with a mass fraction of 2.0% is added to the melted PET slices, stirred evenly, cooled and discharged to obtain graphene-doped antistatic PET slices, which are then prepared by melt spinning. Graphene has good conductivity, and a lower content of graphene can well improve the conductive properties of polyester fibers. Adding 2.0% of graphene can reduce the mass resistivity of polyester by about 5 orders of magnitude, has good antistatic properties, and can reduce dust adsorption caused by static electricity during the use of fabrics.

[0016] The hydrophilic groups and pore structure of the Celis biodegradable fiber make it have excellent hydrophilicity. When the fabric meets water, the Celis biodegradable fiber interacts with water, the fiber / water phase interfacial tension is weak, and the oil / fiber phase cross-sectional tension is strong, so that the dirt and the fabric are easily separated through external mechanical action.

[0017] The triple-proof finishing agent is FK-5617 triple-proof finishing agent, which has excellent performance in water resistance, oil resistance, liquid stain resistance and solid stain resistance, with a waterproof performance of 95 points, an oil resistance level of above level 6, liquid stain resistance of up to level 5, and solid stain resistance of above level 4, which can fully meet the anti-fouling needs of curtain fabrics encountered in daily life.

[0018] The stain-resistant layer 1 can achieve excellent stain-resistant function based on the three-proof finishing agent attached to the yarn surface. When the three-proof finishing agent is partially removed by friction and washing after long-term use, the anti-static yarn of the stain-resistant layer 1 can reduce the dust adsorbed by static electricity. The biodegradable fiber of Celis can make it easy to clean fabrics that are accidentally stained with dirt.

[0019] Furthermore, the antibacterial layer 2 is formed by interweaving silver ion antibacterial modified polyester filaments as warp yarns and honeycomb negative ion modified polyester fiber yarns as weft yarns.

[0020] Furthermore, the specification of the silver ion antibacterial modified polyester filament is 75D / 72F, and the fineness of the honeycomb negative ion modified polyester fiber yarn is 130D.

[0021] The silver ion antibacterial modified polyester filament is made by melt spinning of silver antibacterial agent and polyester chips, and the honeycomb negative ion modified polyester fiber is made by blending and spinning modified polyester staple fibers with a honeycomb microporous structure that penetrates inside and outside. The high temperature resistance of the silver antibacterial agent is better than that of the organic antibacterial agent, and the antibacterial strength is high, and it has the function of inhibiting the reproduction of bacteria and fungi. The fabric woven from the honeycomb negative ion modified polyester fiber yarn can release a large amount of negative oxygen ions through friction. Negative oxygen ions refer to oxygen ions that have gained one or more electrons and are charged. They can affect the physiological activities of the human body through the human nervous system and blood circulation, which is beneficial to the physical and mental health of the human body. A large amount of negative oxygen ions can purify the air, and at the same time can purify the blood and enhance resistance.

[0022] Furthermore, the specification of the black full-dull polyester fiber filament is 300D / 288F. Full-dull polyester fiber is obtained by adding titanium dioxide to the polymer slices, so that the fiber scatters light and eliminates the gloss to reduce the transparency. When the light passing through the formaldehyde removal layer 4 reaches the light shielding layer 3, the characteristics of the full-dull polyester fiber can be used to reduce the amount of light transmitted, thereby achieving a light shielding effect. Combined with the black color of the fiber, the darker the color, the lower the light transmittance of the fabric, and the better the light shielding performance.

[0023] Photocatalyst fiber is a modified polyester fiber containing nano titanium dioxide. The surface of the photocatalyst fiber is uneven, with grooves of varying depths, and is distributed with nano titanium dioxide. The nano titanium dioxide on the surface generates hydroxyl radicals under light conditions, which react with organic matter in the air to generate non-toxic inorganic substances, which can effectively decompose formaldehyde, benzene, ammonia, etc., and convert them into water and carbon dioxide, thereby playing the role of air purification. The photocatalyst fiber has high chemical stability, is non-toxic and harmless to the human body, and the photocatalyst formaldehyde removal method can be used multiple times, which is a green and environmentally friendly way to remove odors. When the stain-resistant polyester fabric is used to make curtains, the formaldehyde removal layer 4 is arranged on a side close to outdoor light, so that when sunlight shines on the fabric surface during the day, the photocatalyst fiber can achieve the function of removing formaldehyde.

[0024] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
