Problems solved by technology

[0003] 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.
[0004] 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

[0030] The first step is the preparation of nano-silver coated with modified starch, the method is as follows:

[0031] (1) the silver nitrate solution of preparation 0.05mol / L and the sodium citrate solution that concentration is 1% are subsequent use;

[0032] (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;

[0033] (3) Lower the temperature to 70°C, add dropwise 10ml of the prepared silver nitrate solution into the three-necked flask, and continuously stir for 10 minutes;

[0034] (4) Add 2ml of the prepared sodium citrate solution dropwise at a rate of 1 drop / s, and stir to make it fully react;

[0035] (5) After the color of the reaction system no longer changes, that is, after the reaction is sufficient, the prepared sol is taken out from the reaction ...

Embodiment 2

[0049] 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.

[0050] The third step gray cloth pretreatment

[0051] (1) prepare the sodium hydroxide solution that concentration is 2% by 40ml / g fabric ratio;

[0052] (2) Put the fabric into the lye and boil it for 10 minutes before taking it out;

[0053] (3) Rinse the fabric with clean water until the inspection is completed.

[0054] Step 4: Two dipping and two rolling in the same bath

[0055] (1) Padding finishing agent: take 60g / L of self-made composite three-proof antibacterial finishing agent, and adopt two dipping and two rolling processes under the conditions of padding temperature 20°C and rolling liquid rate of 80%;

[0056] (2) Drying: Dry with hot air at 110°C for 2 minutes;

[0057] (3) Baking: at 175°C, bake for 90s;

[0058] (4) Cloth output: Finally, the finished fabric is processed to pr...

Embodiment 3

[0060] 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.

[0061] The third step gray cloth pretreatment

[0062] (1) prepare the sodium hydroxide solution that concentration is 2% by 30ml / g fabric ratio;

[0063](2) Put the fabric into the lye and boil it for 10 minutes before taking it out;

[0064] (3) Rinse the fabric with clean water until the inspection is completed.

[0065] Step 4: Two dipping and two rolling in the same bath

[0066] (1) Padding finishing agent: Take 30g / L of self-made composite three-proof antibacterial finishing agent, and adopt two dipping and two rolling processes under the conditions of padding temperature 30°C and rolling liquid rate of 75%;

[0067] (2) Drying: Dry with hot air at 120°C for 2 minutes;

[0068] (3) Baking: at 165°C, bake for 90s;

[0069] (4) Cloth output: Finally, the finished fabric is processed to pro...

Abstract

The invention discloses a high-performance three-proofing antibiotic fabric and finishing method thereof. The high-performance three-proofing antibiotic fabric is obtained by one-bath finishing cotton woven by using a compound three-proofing antibiotic finishing agent composed of a nano-silver sol antibiotic finishing agent, an HS1100 three-proofing finishing agent, an ATB9800 antibiotic finishing agent and a TPM9007antibactrial finishing agent. Starch which is a natural degradable polymer is used as a protective agent and a dispersing agent, and a simple liquid-phase chemical reduction method is used for preparing starch cladded nano-silver sol, the process is simple and environment-friendly, the nano-silver sol is good in dispersibility and hard to reunite. The prepared nano-silver three-proofing antibiotic finishing agent can be used for one-bath finishing, and is simple in process and convenient for operation in comparison with dividing-bath finishing.

Description

technical field [0001] The invention relates to a three-proof antibacterial fabric and a finishing method thereof. Background technique [0002] 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. [0003] At present, separate baths are basically used for finishing, and separate baths for three defenses + antibacterial means first three defenses and then antibacterial or first antibacterial and then three defenses finishing. This process ma...
