Problems solved by technology

[0004] However, since the active ingredients in Radix isatidis are generally not well adsorbed on fabrics, the active ingredients in Radix isatidis will be lost during long-term wearing or washing, and the antibacterial ability of fabrics will be weakened.

preparation example 1～15

[0058] A modified isatis root fiber is modified through the following technical solutions:

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

[0060] S2. Soak the isatis root fiber in the above modifier under the condition of 40±2℃, and the soaking time is 2h;

[0061] S3. The soaked isatis root fiber is heat treated in an oven at a temperature range of 65±1° C., and the heat treatment time is 5 hours to obtain a modified isatis root fiber.

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

[0063] Table of parts by mass of each component in Preparation Examples 1-15

[0064]

[0065] Wherein, polycarboxylic acid selects maleic anhydride for use, catalytic acid is sulfuric acid, stearate is calcium stearate, antistatic agent is universal permanent antistatic agent (see Table 1 for purchase source), and surfactant is stearate Wen-60.

preparation example 16

[0067] A modified isatidis fiber, the difference from Preparation Example 1 is that the catalytic acid is hydrogen chloride.

preparation example 17

[0069] A modified isatidis fiber, the difference from Preparation Example 1 is that succinic anhydride is selected as the polycarboxylic acid.

Abstract

This application relates to the field of fabrics, more specifically, it relates to a composite isatis root fabric, including a functional fabric layer, the functional fabric layer is made of reactive fibers obtained by blending modified isatis root and nylon fiber, wherein the modified isatis root fiber It is obtained by immersing isatis root fiber in an aqueous solution containing polycarboxylic acid, chitosan, catalytic acid and other additives, and then heat-treating. The above-mentioned isatidis composite fabric reduces the loss of active antibacterial substances in the isatidis in the washing process through chitosan, and improves the long-term antibacterial effect of the isatidis composite fabric.

Description

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