Preparation method of washable three-proofing and easy-decontamination antibacterial fabric

Abstract

The invention discloses a preparation method of a washable three-proofing and easy-decontamination antibacterial fabric. The preparation method is characterized by comprising the following steps of: soaping, to be specific, after desizing, scouring, bleaching and mercerizing the fabric in advance, removing impurities on the cloth cover by a soaping process, and then drying; and performing one-bathprocess washable three-proofing and easy-decontamination antibacterial finishing, to be specific, shaping and processing the soaped and dried fabric on a shaping machine, drying, baking and finishing, thereby obtaining the washable three-proofing and easy-decontamination antibacterial fabric. A working solution which simultaneously contains a C6 durable three-proofing finishing agent, a purifiedcotton durable fluorine-free waterproof agent, a durable crosslinking agent, an antibacterial agent and a special waterproof penetrant is contained in a rolling groove of the shaping machine, and thefabric is subjected to padding, then is dried and baked to obtain the washable three-proofing and easy-decontamination antibacterial fabric. The preparation method solves the contradiction between thethree-proofing and the easy decontamination, and also solves the problems between the three-proofing and the bacteria prevention; and meanwhile the fabric is endowed with the function of washing resistance, and can meet the overall actual needs for functional fabrics in actual situations.

Description

technical field [0001] The invention belongs to the technical field of textile manufacturing, relates to an antibacterial fabric, in particular to a preparation method of a washable three-proof and easy-to-decontamination antibacterial fabric. Background technique [0002] With the improvement of people's living standards, the consumption of high-end hotels for family trips and tourism is getting higher and higher, which requires hotels to provide multi-functional protective textiles to meet the needs of consumers. At present, textiles with water-resistant, three-proof and easy-to-decontamination protection not only need to meet the protection against water-based stains during wearing and the easy cleaning after contamination, but also have higher requirements for their antibacterial properties. At present, the three-proof and easy-to-decontamination linen and medical protective products need to solve the following problems: First, the three-proof and easy-to-decontamination...

Problems solved by technology

At present, the three-proof and easy-to-decontamination linen and medical protective products need to solve the following problems: First, the three-proof and easy-to-decontamination are inherently contradictory. The water repellency of the fabric; the second is that the antibacterial additives added to the conventional three-proof will reduce the initial and washable performance of the three-proof. It needs to be screened to have good antibacterial performance and have no effect on the three-proof easy to decontaminate and washable. Third, the initial water repellency of the current three-proof and easy-to-decontamination products is only about 90 points, which has not fully reached the 100 points similar to the lotus leaf water repellency effect. It is necessary to improve the water repellency protection effect of the fabric , and the oil repellency of the three-proof products currently on the market can only reach about 4-5 levels, and the initial oil repellency of the fabric needs to be improved; Fourth, the above-mentioned multi-functions are currently satisfied at the same time, and the shaping process requires a multi-step method, and the shaping is first If the antibacterial agent is reprocessed for three defenses, the three defenses will wrap the antibacterial agent on the fabric, and the fabric has washable and antibacterial properties, but has no initial antibacterial performance; No, there is a certain contradiction between three-proof and antibacterial finishing; therefore, a simple preparation technology that can be processed in the same bath is required to meet the excellent three-proof, easy-to-decontaminate, antibacterial and washable preparation technology

[0003] The Chinese patent with the publication number CN103343450 B discloses a three-proof and easy-to-decontaminate textile fabric and its preparation method. Although it has initial water-repellent, oil-repellent and easy-to-contaminate effects, its initial water-repellent performance has not reached 95%. The points are above, and it does not explain the effect of the anti-fouling test in the three-proof, and it does not explain the effect of the three-proof and easy-to-decontamination and washing resistance, and it first passes the method of pre-setting the resin and then finalizes the three-proof auxiliary agent + easy to remove Stain finishing agents, hydrophilic and easy-to-decontamination finishing agents affect the initial water repellency of the three-proof additives, the cost of the additives is high, the processing steps are many, the processing is not easy, and the process is not completely improved; and there is no explanation for this The interaction between the three-proof technology and other functional additives does not explain the relationship between the three-proof and antibacterial, and it cannot meet the requirements for taking it in hotel linen and medical white coats

[0004] The Chinese patent with the publication number CN102051824A discloses a preparation method for waterproof, oil-proof, stain-proof and easy-to-decontamination home fabrics. It makes the fabric realize the functions of three-proof and easy decontamination, but because it only simply handles the fabric through the configuration of preparation materials, and does not make corresponding improvements in the manufacturing process, it is difficult to ideally solve the three-proof The contradiction between finishing and decontamination finishing cannot satisfy the hotel's three-proof, easy-decontamination, breathable imitation drill fleece and washability. The actual situation has a comprehensive practical demand for functional fabrics

[0005] The Chinese patent with the publication number CN102021842A discloses a method for making a water-repellent fabric without PFOA and PFOS. It discloses a method for making a water-repellent fabric that does not contain fluorocarbons such as perfluorooctanoic acid and its salts. Although it can be waterproof to a certain extent, However, due to the selection and configuration of its raw materials and its production process, it cannot meet the requirements for the three-proof function of the fabric, nor does it solve the contradiction between the three-proof finishing and the easy-to-decontamination finishing, so it cannot meet the actual situation. actual needs
