Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular to a wear-resistant and light-resistant velvet cloth and a preparation method thereof. Background Art

[0002] As a high-quality textile fabric, velvet is widely used in clothing, curtains, cushions, draperies, etc. for its soft feel, tight pile and unique visual effects. However, traditional velvet has shortcomings in wear resistance and light resistance, and it is difficult to meet the needs of modern consumers for high-quality fabrics.

[0003] Traditional chopped flannel usually uses strong twisted silk as the ground warp and ground weft, with two S-twisted and two Z-twisted warps and two layers of fabric interwoven in plain weave, while the flannel warp uses glossy viscose rayon to be fixed in a "W" shape on the upper and lower base silks. This structure gives chopped flannel a soft feel and dense fluff, but its performance in terms of wear resistance and light resistance is average.

[0004] How to maintain the original hydrophilicity and softness of the velvet fabric while improving its wear resistance is a major technical challenge. Wear-resistant treatment often makes the fabric hard and deteriorates its hydrophilicity, which also affects the wearing comfort and appearance. Therefore, the present invention proposes a wear-resistant and light-resistant velvet fabric and a preparation method thereof to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a wear-resistant and light-resistant velvet cloth and a preparation method thereof, which can improve the hydrophilicity and softness of the velvet cloth while ensuring the wear resistance of the velvet cloth.

[0006] In a first aspect, the present invention provides a wear-resistant and light-resistant flannel cloth, comprising a flannel cloth base fabric and a wear-resistant and light-resistant coating coated on the surface thereof; the wear-resistant and light-resistant coating comprises the following raw materials in parts by weight: 60-70 parts of modified water-based polyurethane resin, 20-26 parts of modified acrylic resin, 4-5 parts of silicone wear-resistant agent, 1-2 parts of dispersant, 0.5-1 part of light-resistant agent, and 45-55 parts of deionized water.

[0007] Furthermore, the preparation method of the modified waterborne polyurethane resin comprises: mixing 2-3 parts of nano-Al2O3 with 80-90 parts of waterborne polyurethane emulsion, emulsifying with FA25, and dispersing for 25-35 minutes at a rotation speed of 9000-10000 r / min.

[0008] Furthermore, the preparation method of the modified acrylic resin includes: ultrasonically dispersing attapulgite in ethanol, adding a silane coupling agent to modify the modified attapulgite, adding it to an aqueous solution of methacrylic acid and butyl acrylate monomers, polymerizing at 74-78°C for 4-6 hours under the action of ammonium persulfate, cooling to room temperature, and adjusting the pH value to 6.

[0009] Furthermore, the dosage ratio of the attapulgite, ethanol and silane coupling agent is (2-3) g: (15-20) mL: (8-10) g.

[0010] Furthermore, the silane coupling agent includes at least one of KH550, KH560 and KH570.

[0011] Furthermore, the weight ratio of the modified attapulgite, methacrylic acid, butyl acrylate and ammonium persulfate is (1-2): (20-30): (15-20): (0.2-0.4).

[0012] Furthermore, the organic silicon wear-resistant agent is polyether-modified organic silicon oil WR690.

[0013] Furthermore, the dispersant is BYK-161 and / or BYK-163.

[0014] Furthermore, the light stabilizer is rutile titanium dioxide.

[0015] In a second aspect, the present invention provides a method for preparing a wear-resistant and light-resistant velvet cloth, the steps comprising: (1) preparing a modified waterborne polyurethane resin; (2) preparing a modified acrylic resin; (3) mixing the modified waterborne polyurethane resin, the modified acrylic resin, an organosilicon wear-resistant agent, a dispersant, a light-resistant agent and deionized water, and coating the mixture on the surface of the velvet cloth, wherein the coating thickness is 0.5-1 mm.

[0016] The beneficial effects of the present invention are: The invention not only enhances the mechanical strength of polyurethane resin but also improves its wear resistance by adding nano-Al2O3; the nano-particles are evenly dispersed in the resin to form an effective wear-resistant layer, which effectively resists external wear. In addition, the water-based polyurethane resin itself has good hydrophilicity and softness, and the amount of nano-Al2O3 added is precisely controlled to avoid the problem of hardening of the coating caused by excessive addition, thereby maintaining the softness and hydrophilicity of the coating. In addition, the nano-Al2O3 particles are evenly dispersed in the polyurethane resin to form a nano-composite structure. This structure not only improves the mechanical strength of the resin, but also significantly enhances the wear resistance of the coating through the filling effect and interface interaction of the nano-particles. The small size effect and surface effect of the nano-particles enable them to effectively disperse stress when subjected to external forces and prevent the coating from breaking.

[0017] The present invention utilizes attapulgite modified by a silane coupling agent, and copolymerized with methacrylic acid and butyl acrylate monomers, and the obtained modified acrylic resin has higher hardness and wear resistance. At the same time, the nano effect of the attapulgite further enhances the wear resistance of the coating. In addition, after the attapulgite is modified by a silane coupling agent, its surface properties are improved and its compatibility with the acrylic resin is enhanced. The modified attapulgite is more evenly dispersed in the acrylic resin, and the formed composite resin has higher hardness and wear resistance. At the same time, the nano structure of the attapulgite also plays a role in enhancing wear resistance.

[0018] The present invention adopts a step-by-step modification method, firstly utilizes nano-Al2O3 to modify polyurethane resin, and then utilizes attapulgite modified by silane coupling agent to modify acrylic resin, which has a significant beneficial effect compared with directly mixing nano-Al2O3, polyurethane resin, attapulgite, silane coupling agent, acrylic resin and other additives. Through step-by-step modification, each material can be modified under the most suitable conditions, so as to maximize its performance advantages. Compared with direct mixing, step-by-step modification avoids possible adverse interactions between different materials, such as phase separation, agglomeration, etc., and ensures the uniformity and stability of the coating. Nano-Al2O3 modified polyurethane resin and modified attapulgite modified acrylic resin synergistically act with each other in the coating, which not only enhances the wear resistance of the coating, but also improves the hydrophilicity and softness of the velvet cloth by optimizing the microstructure and surface properties of the coating.

[0019] In the present invention, polyether-modified silicone oil is selected as the anti-wear agent. Its unique molecular structure can form a smooth and wear-resistant protective film on the surface of the coating, further improving the wear resistance of the coating. DETAILED DESCRIPTION
