Problems solved by technology

This type of method is usually difficult to take into account the indicators of antibacterial performance, hand feel and durability
(2) By adding antibacterial fibers, further obtaining antibacterial yarns, weaving, and obtaining fabrics, the disadvantage is that the added antibacterial fibers such as bamboo, hemp, and chitin have poor antibacterial properties, so they need to be added in large quantities in fabrics. At least above 30%, which will greatly affect the comfort and feel of the towel
The disadvantage is that this kind of antibacterial is also achieved through finishing, which is difficult to last and affects the feel
[0011] Apparently, in the published information, no antibacterial method has been found, which can meet the above three requirements of towel fabric at the same time

Embodiment 1

[0047] 0.5% by weight of silver-chelated acrylic fiber and 99.5% by weight of long-staple cotton fiber blended yarn, as loop yarn, consolidated on the base fabric with pure cotton yarn as the ground warp, to form towel gray cloth. Wherein, the silver content of the silver chelated acrylic fiber is 5% by weight.

[0048] A controllable antibacterial towel containing silver chelated acrylic fibers, the preparation steps of which are as follows:

[0049] (1) Preparation of blended yarn: pre-drawn commercially available silver chelated acrylic fibers are fed together with conventional commercially available fiber laps on the carding machine to make a carding raw material mixed with silver chelated acrylic fibers and conventional fibers. Further, use the mixed carding sliver of conventional fiber / silver chelated acrylic fiber and the carding sliver of conventional fiber to match in proportion on the drawing frame, make the silver chelated acrylic fiber in conventional fiber after t...

Abstract

The invention relates to a controllable antibacterial towel containing silver-chelated acrylic fibers and a making method of the towel, and belongs to the technical field of daily used textiles. Yarns of the controllable antibacterial towel are blended yarns composed of 0.4%-3% by weight of silver-chelated acrylic fibers and conventional fibers, the content of the silver-chelated acrylic fibers ranges from 0.4 wt% to 1.5 wt%, the blended yarns are terry yarns fixed on ground yarns, and the blended yarns simultaneously serve as the terry yarns and the ground yarns. The silver ion content of the controllable antibacterial towel before and after being washed for 50 times is not lower than 50 ppm, and the controllable antibacterial towel has a bacteriostasis rate of 90% or above on gram-positive bacteria, gram-negative bacteria and fungi. In the washing process, if the towel fabric is washed with other clothes, the same bactericidal effect on other clothes can be achieved.

Description

technical field [0001] The present invention relates to an antibacterial towel and a preparation method thereof, more specifically to a controllable antibacterial towel containing silver chelated acrylic fibers and a preparation method thereof, which refers to adding silver chelated antibacterial fibers in a small proportion and a special dyeing and finishing process The obtained towel with durable and controllable antibacterial properties belongs to the technical field of daily textiles. Background technique [0002] Towel products are daily-use textiles with a large quantity and a wide range. On the one hand, the frequency of use is high, and it is often placed in an environment with high humidity such as the bathroom, which is easy to breed bacteria. On the other hand, in hot summer, towels are often used as sweat wipes. Bacteria are more likely to breed in high-temperature, high-humidity, sweaty environments rich in human dander, and such towels usually have an unpleasa...
