NOVELTY - Preparing an antibacterial fabric containing silver ions involves selecting high-quality natural cotton, removing damaged cotton raw materials, and selecting the quaternary ammonium salt macromolecule antibacterial agent to dissolve in water according to the ratio of 20 kg antibacterial agent per ton of cotton, obtaining the concentration of the antibacterial agent solution, the solution concentration is 50 g/L, and then spraying the antibacterial agent liquid on the cotton, putting for 45-50 hours at a temperature of 17-23 degrees C and a relative humidity of 55-60%, combing the treated cotton material with a comb in order to obtain a cotton fiber sliver with aligned fibers, each cotton fiber sliver is composed of 8-10 cotton fibers arranged in parallel. After drying the treated cotton fiber strips, go through the processes of carding, combing, drawing, roving and spinning, the antibacterial yarn can be obtained. USE - Method for preparing an antibacterial fabric containing silver ions. ADVANTAGE - The method enables to prepare an antibacterial fabric containing silver ions, which maintains the antibacterial effect, is stable and lasting, do not cause damage to the cotton fiber, silver ion spandex yarn is also blended during the weaving process, which greatly enhances its antibacterial performance, and the cotton base cloth is wrapped inside by a wear-resistant fabric, avoid the abrasion of the surface after long-term use, and since the wear-resistant fabric is bonded with the cotton base cloth, andlayer of antibacterial liquid is sprayed and cured on the surface, so that the wear-resistant fabric itself has certain antibacterial properties. DETAILED DESCRIPTION - Preparing an antibacterial fabric containing silver ions involves selecting high-quality natural cotton, removing damaged cotton raw materials, and selecting the quaternary ammonium salt macromolecule antibacterial agent to dissolve in water according to the ratio of 20 kg antibacterial agent per ton of cotton, obtaining the concentration of the antibacterial agent solution, the solution concentration is 50 g/L, and then spraying the antibacterial agent liquid on the cotton, putting for 45-50 hours at a temperature of 17-23 degrees C and a relative humidity of 55-60%, combing the treated cotton material with a comb in order to obtain a cotton fiber sliver with aligned fibers, each cotton fiber sliver is composed of 8-10 cotton fibers arranged in parallel. After drying the treated cotton fiber strips, go through the processes of carding, combing, drawing, roving and spinning, the antibacterial yarn can be obtained. The antibacterial yarn is mercerized in a yarn mercerizing machine, and then a slit warping machine is used for warping. The warping speed is 180-190m/min, the reversing speed is 120-140m/min, then weave the warped antibacterial yarn through the weaving process and add silver-ion spandex yarn inside to obtain a cotton base cloth. The benzonitrile group ionized modified 2,3,5,6-tetrafluoroterephthalic acid/3,3'-diaminodipropylamine polycondensate and vinyl fluorosilicone oil coated modified graphene hollow nanofibers and join the twin-screw spinning machine for melt spinning to obtain wear-resistant fiber. The wear-resistant fiber is woven with a large circular machine to obtain a gray fabric, which is then sequentially dyed, pre-shaped, soft dehydrated, and dried to obtain a wear-resistant fabric. The cotton base fabric and the wear-resistant fabric are washed open-width through a washing machine in turn. The wear-resistant fabrics are sequentially bonded on both sides of the cotton base fabric with an adhesive to obtain semi-finished antibacterial fabrics. The surface of the semi-finished antibacterial fabric is dust-removed, and then it passes through the feeding flattening device, the first spraying device, the pressing device and the second spraying device in sequence. The right end of the semi-finished antibacterial fabric is wound and fixed on the winding roller. The winding roller is in the process of winding the semi-finished antibacterial fabric. The antibacterial fabric semi-finished product is flattened by the feed flattening device. The antibacterial fabric semi-finished product is flattened. The antibacterial liquid is first sprayed on the surface of the semi-finished antibacterial fabric through the primary spraying device, and the antibacterial liquid is sprayed again on the surface of the semi-finished antibacterial fabric through the secondary spraying device. During the spraying process of the antibacterial liquid, the semi-finished antibacterial fabric sprayed by the initial spraying device is pressed through the pressing device. After standing for a period of time, it is removed and heat-treated at 85 degrees C to obtain the finished antibacterial fabric.
