preparation example 1～15

[0058] A modified Radix isatidis fiber is modified through the following technical scheme:

[0059] S1. Configure the modifier according to a fixed ratio;

[0060] S2. Soak the Radix isatidis fiber in the modifier above at 40±2°C for 2 hours;

[0061] S3. Heat the soaked Radix isatidis fibers in an oven at a temperature range of 65±1° C. for 5 hours to obtain modified Radix isatidis fibers.

[0062] The modifier formulations in Preparation Examples 1-15 are specifically shown in Table 2.

Abstract

The invention relates to the field of cloth, in particular to a radix isatidis composite fabric which comprises a functional fabric layer formed by warp knitting of active fibers obtained by blendingof modified radix isatidis and polyamide fibers. The modified radix isatidis fibers are obtained by soaking radix isatidis fibers in an aqueous solution containing polycarboxylic acid, chitosan, catalytic acid and other assistants and then carrying out heat treatment. According to the radix isatidis composite fabric, loss of active antibacterial substances in the radix isatidis in the washing process is reduced through the chitosan, and the long-acting antibacterial effect of the radix isatidis composite fabric is improved.

Description

technical field [0001] This application relates to the field of cloth, more specifically, it relates to a composite fabric of Radix isatidis. Background technique [0002] Radix isatidis is a kind of traditional Chinese herbal medicine. Due to the presence of various active substances in Radix isatidis (such as indole alkaloids, small molecular organic acids, flavonoids, etc.), it has certain antibacterial and antiviral activities. [0003] Radix isatidis fiber is a kind of fiber added with active ingredient of Radix isatidis, which has certain antibacterial effect. By spinning isatidis fibers, the antibacterial activity of isatidis itself can be incorporated into fabrics, and then fabrics with certain antibacterial activities can be obtained. [0004] However, since the active ingredients in Radix isatidis are generally not well adsorbed on fabrics, during long-term wearing or washing, the active ingredients in Radix isatidis will be lost, and the antibacterial ability of ...
