The invention relates to a controllable antibacterial
textile and a preparation method thereof and belongs to the technical field of textiles for daily use. The controllable antibacterial
textile is formed by taking more than 3% of silver chelated
chitosan fibers and blended yarns spun by conventional fibers as weft and warp yarns, or blended yarns with the content of the silver chelated
chitosan fibers of 2%-10% and the conventional yarns through interval arrangement, and grey cloth is formed by adopting a certain tissue structure; the grey cloth is subjected to procedures of
desizing, scouring and bleaching,
dyeing, shaping and the like by adopting a specific pH value to prepare the
textile; the silver content of the prepared textile is not lower than 50ppm after the textile is washed for 50 times; and after the textile meets water with ions (common
tap water), the textile has
extremely good silver releasing performance. On the basis of keeping the performance of a previous conventional
fiber textile, the textile also provides lasting and controllable antibacterial performance and can be used for various types of textiles including
bedding, shirts, underwear and the like which are close to
skin.
