Technical Field

The invention belongs to the technical field of textile manufacturing, relates to an antibacterial fabric, and particularly relates to a preparation method of a washable, three-proofing and soil-release antibacterial fabric.

Background

With the increasing living standard of people, the consumption level of high-grade hotels by family trips, travels and the like is also higher, so that the hotels need to provide multifunctional protective textiles to meet the requirements of consumers. At present, textiles with water-washing-resistant, three-proofing and soil-release protection need to meet the requirements of water-based stain protection in the process of taking the textiles and easy cleaning after staining, and the antibacterial performance of the textiles also obtains higher requirements more and more. At present, the problems to be solved by three-proofing soil release linen and medical protection products are as follows: firstly, two aspects of three proofness and easy decontamination are contradictory, and the water repellency of the fabric is influenced instead of hydrophilic performance required by the easy decontamination; the conventional three-proofing added antibacterial auxiliary can reduce the initial and water washing resistance of three proofing, and a water washing-resistant antibacterial auxiliary which has good antibacterial performance and does not influence the three-proofing, easy decontamination and water washing resistance is required to be screened; thirdly, the initial water repellency of the existing three-proofing and soil-release product is only about 90 minutes, the water repellency protection effect of the fabric needs to be improved if the initial water repellency of the three-proofing and soil-release product is not completely 100 minutes which is similar to the water repellency effect of lotus leaves, the oil repellency of the existing three-proofing product on the market can only reach about 4-5 grades, and the initial oil repellency of the fabric needs to be improved; fourthly, at present, the multifunctional performance is simultaneously met, a multi-step method is needed for shaping and processing, firstly, the shaping and finishing of the antibacterial agent are carried out, then, the three protection of the antibacterial agent is carried out, the antibacterial agent is wrapped on the fabric by the three protection of the antibacterial agent, and the fabric has the washing-resistant antibacterial performance and has no initial antibacterial performance; firstly, shaping and processing a three-proofing auxiliary agent, and then processing the antibacterial performance, so that the antibacterial auxiliary agent cannot be used for padding, and certain contradiction exists between three proofing and antibacterial finishing; therefore, a simple preparation technology which can be processed in one bath and simultaneously meets excellent three-proofing, soil-release, antibacterial and water-washing resistance is needed.

The Chinese patent with publication number CN 103343450B discloses a three-proofing soil-release textile fabric and a preparation method thereof, although the fabric has initial water-repellent, oil-repellent and soil-release effects, the initial water-repellent performance does not reach more than 95 minutes, the effect of an antifouling test in three proofing is not described, the effect of three proofing, soil-release and washing resistance is not described, and the three-proofing auxiliary agent and the soil-release finishing agent are shaped after a resin is shaped in advance, the hydrophilic soil-release finishing agent influences the initial water-repellent performance of the three-proofing auxiliary agent, the auxiliary agent has high cost and multiple processing steps, the processing is simple and convenient, and the process is not completely improved; and the problem of mutual influence between the three-proofing process and other functional additives is not described, and the relationship between three proofing and antibiosis is not described, so that the taking requirements of the three-proofing process on hotel cloth grass and medical white gowns cannot be met.

The Chinese patent with publication number CN102051824A discloses a preparation method of a waterproof, oil-proof, antifouling and easily-decontaminable household fabric, and discloses an antifouling and easily-decontaminable after-finishing method of the household fabric, which can enable the fabric to realize the functions of three prevention and easy decontamination to a certain extent, but because the fabric is only subjected to corresponding treatment by preparation material configuration and the manufacturing process method is not correspondingly improved, the contradiction between the two aspects of three prevention finishing and easy decontamination finishing is difficult to ideally solve, the ultra-soft hand feeling characteristic of the three prevention easily-decontaminable breathable diamond-like velvet and washable performance for hotels is difficult to realize, and the comprehensive actual requirement of the actual situation on the functional fabric is also difficult to meet.

Chinese patent publication No. CN102021842A discloses a method for making PFOA-and PFOS-free water repellent technical fabric, which discloses a method for making a water repellent fabric of fluorocarbon compound containing no perfluorooctanoic acid and its salt, although the fabric can be waterproof to a certain extent, the selection and configuration of the raw materials and the process for making the fabric do not satisfy the requirement for the three-proofing function of the fabric, and also do not solve the contradiction between the three-proofing finishing and the easy decontamination finishing, so that the actual requirement for the functional fabric in the actual situation cannot be satisfied.
