Problems solved by technology

[0004] At present, separate baths are basically used for finishing, and separate baths and three defenses + antibacterial means first three defenses and then antibacterial or first antibacterial and then three defenses finishing. This process makes the three defenses and antibacterial properties interact with each other, and the process is complicated and the process is long.
[0005] Generally, the same-bath finishing of nano-antibacterial agents will reduce the stability of the three-proof and antibacterial composite finishing liquid, and even cause precipitation during the same-bath finishing process. In order to overcome the above shortcomings, a simple process, convenient operation, and good safety are provided. Nano-silver three-proof antibacterial composite finishing agent in the same bath finishing method

Embodiment 1

[0031] The first step is the preparation of nano-silver coated with modified starch, the method is as follows:

[0032] (1) Prepare 0.05mol / L silver nitrate solution and 1% sodium citrate solution for later use;

[0033] (2) Add 50ml of water into the three-necked flask, then add 0.25g of modified starch, turn on the heat-collecting constant temperature heating magnetic stirrer, put the above three-necked flask into it, stir and heat up to 95°C for about 30min to gelatinize the starch;

[0034] (3) Lower the temperature to 70°C, drop 10ml of the prepared silver nitrate solution into the three-necked flask, and continuously stir for 10 minutes;

[0035] (4) Add 2ml of the prepared sodium citrate solution dropwise at a rate of 1 drop / S, and stir to make it fully react;

[0036] (5) After the color of the reaction system no longer changes, that is, after the reaction is complete, the prepared sol is taken out of the reaction flask and cooled naturally.

[0037] The second step ...

Embodiment 2

[0050] The composite three-proof antibacterial finishing agent is prepared, and its preparation steps and process are the same as the first step and the second step of Example 1.

[0051] The third step gray cloth pretreatment

[0052] (1) Prepare a sodium hydroxide solution with a concentration of 2% according to the proportion of 40ml / g fabric;

[0053] (2) Boil the fabric in lye for 10 minutes and take it out;

[0054] (3) Rinse the fabric with clean water until the inspection returns.

[0055] Step 4: Two dipping and two rolling in the same bath

[0056] (1) Padding finishing agent: take 60g / L of self-made composite three-proof antibacterial finishing agent, and adopt the two-dipping and two-rolling process under the conditions of padding temperature 20°C and rolling liquid rate 80%;

[0057] (2) Drying: Dry with hot air at 110°C for 2 minutes;

[0058] (3) Baking: Baking at 175°C for 90s;

[0059] (4) Fabric out: Finish the final processing and out of the fabric, tha...

Embodiment 3

[0061] The composite three-proof antibacterial finishing agent is prepared, and its preparation steps and process are the same as the first step and the second step of Example 1.

[0062] The third step gray cloth pretreatment

[0063] (1) Prepare a sodium hydroxide solution with a concentration of 2% according to the proportion of 30ml / g fabric;

[0064] (2) Boil the fabric in lye for 10 minutes and take it out;

[0065] (3) Rinse the fabric with clean water until the inspection returns.

[0066] Step 4: Two dipping and two rolling in the same bath

[0067] (1) Padding finishing agent: take 30g / L of self-made composite three-proof antibacterial finishing agent, and adopt the two-dipping and two-rolling process at the padding temperature of 30°C and the rolling rate of 75%;

[0068] (2) Drying: Dry with hot air at 120°C for 2 minutes;

[0069] (3) Baking: Baking at 165°C for 90s;

[0070] (4) Fabric out: Finish the final processing and out of the fabric, that is, high-perfo...

Abstract

The invention discloses a high-performance three-proofing anti-bacterial fabric finishing method with a simple process. A high-performance three-proofing anti-bacterial fabric is obtained by performing one bath dyeing and finishing on a cotton fabric by using a composite three-proofing anti-bacterial finishing agent prepared from a nano silver colloid anti-bacterial finishing agent, an HS1100 three-proofing finishing agent, an ATB9800 anti-bacterial finishing agent and a TPM9007 anti-bacterial finishing agent. According to the method, natural and degradable macromolecules, i.e., starch is taken as a protective agent and a dispersant, and a simple liquid phase chemical reduction method is adopted to prepare nano silver colloid coated with the starch, so the process is simple, greening and environment protection are realized, the dispersity is good, and the agglomeration possibility is low. The prepared nano silver three-proofing anti-bacterial finishing agent can be used for one bath dyeing and finishing, and is simple in process and convenient to operate relative to separated bath finishing.

Description

[0001] This application is a divisional application with application number: 201410607123.1, application date: 2014.10.31, and name "high-performance three-proof antibacterial fabric and its finishing method". technical field [0002] The invention relates to a three-proof antibacterial fabric and a finishing method thereof. Background technique [0003] In daily life, bedding cannot be washed frequently or the washing time is insufficient, so we can only rely on the traditional sun and ultraviolet rays to kill some harmful fungi and bacteria. Therefore, in the process of use, it is easy to be polluted, resulting in phenomena such as yellowing, mildew, and peculiar smell, which affect the aesthetics, comfort and safety of the product in use. The three-proof antibacterial finishing can endow textiles with waterproof, oil-proof, anti-fouling and antibacterial properties at the same time, which can solve the above problems to a large extent. [0004] At present, separate baths...
