Description

Technical Field

[0001] This invention relates to the field of textile fabrics, specifically to a peppermint fiber antibacterial fabric and its preparation method. Background Technology

[0002] With the development of fabric functionality, peppermint fiber, with its excellent properties, has become a popular material for researchers. Peppermint fiber is made from natural plants, combined with nanotechnology and microencapsulation technology. The effective components of the natural plant—peppermint—are encapsulated in microcapsules and blended with cellulose to form fibers. This ensures the fiber's good skin-friendliness and spinnability, while highlighting its natural, green, and healthy characteristics. However, in addition to excellent skin-friendliness and spinnability, existing fabrics also need to pay more attention to antibacterial properties. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a peppermint fiber antibacterial fabric and its preparation method, wherein the obtained peppermint fabric has high breathability while maintaining good antibacterial properties.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A peppermint fiber antibacterial fabric comprises the following components in parts by weight: 20-30 parts antibacterial agent and 90-100 parts fabric.

[0006] Preferably, the composition includes the following components in parts by weight: 30 parts of antibacterial agent and 100 parts of fabric.

[0007] A method for preparing a peppermint fiber antibacterial fabric includes the following steps:

[0008] Peppermint fiber warp and weft yarns are treated with peppermint essential oil, and then an antibacterial agent is evenly sprayed onto the treated peppermint fiber warp and weft yarns. The yarns are then fed into a loom to produce fabric with a mesh count of 20-25 holes / cm. 2 After drying, rolling, and warehousing, the antibacterial fabric of mint fiber is obtained.

[0009] Preferably, the method for preparing the peppermint essential oil liquid is as follows:

[0010] Mix polylactic acid-glycolic acid copolymer, peppermint essential oil, polyvinyl alcohol and 70% ethyl acetate solution, and stir at 25-30℃ for 2-3 hours to obtain peppermint essential oil solution.

[0011] Preferably, the weight ratio of the polylactic acid-glycolic acid copolymer, peppermint oil, polyvinyl alcohol, and ethyl acetate solution is 1:1:1:2.

[0012] Preferably, the method of treating the peppermint fiber warp and weft yarns with peppermint essential oil includes the following steps:

[0013] Soak the peppermint fiber warp and weft yarns in peppermint essential oil solution and sonicate for 30-40 minutes at an ultrasonic power of 100-150w. Let stand for 12-24 hours, then remove and dry.

[0014] Preferably, the antibacterial agent is prepared by mixing peppermint essential oil, β-cyclodextrin, chitosan, 50% ethanol solution and 50% glacial acetic acid solution, and stirring for 30-40 minutes to obtain the antibacterial agent.

[0015] Preferably, the weight ratio of peppermint oil, β-cyclodextrin, chitosan, ethanol solution and glacial acetic acid solution is 1:1:1:2:2.

[0016] Preferably, the spraying process parameters are: spraying speed of 18-20 m / min and spraying thickness of 0.5-0.6 mm.

[0017] Preferably, the drying process parameters are: drying temperature of 50-60℃ and drying time of 3-5 min.

[0018] The long-chain structure of polylactic acid-glycolic acid copolymer and polyvinyl alcohol in this invention undergoes self-assembly crosslinking with peppermint essential oil. Through electrostatic stabilization, the peppermint essential oil is charged, increasing the contact area and bonding force with the warp and weft yarns of peppermint fibers. This results in increased surface tension and a larger surface contact angle on the peppermint fiber warp and weft yarns after being loaded with peppermint essential oil. Consequently, more peppermint essential oil capsules encapsulated by β-cyclodextrin and chitosan are adsorbed, improving the adsorption stability of the capsules and reducing their adsorption flowability. This further enhances the release stability of peppermint essential oil from the warp and weft yarns, increasing the antibacterial properties of the fabric. Detailed Implementation
