Embodiment 1

[0069] A preparation method of antibacterial pure cotton fabric, comprising the following steps:

[0070] (1) Preparation of photo-induced free radical polymer composite finishing solution:

[0071] Every 1 kilogram of photo-induced free radical macromolecule composite finishing liquid is made up of the following components: the degree of etherification is 78% sulfonated polyetheretherketone 4g; hydrogen atom donor polymer 7g; crosslinking agent 1.8wt% (crosslinking agent Weight accounts for the percentage of sulfonated polyether ether ketone and hydrogen atom donor polymer total weight); An appropriate amount of acetic acid adjusts the pH value of the finishing solution to 5; the balance is deionized water; the hydrogen atom donor polymer is polyvinyl alcohol, The joint agent is glutaraldehyde;

[0072] Preparation steps: Put sulfonated polyether ether ketone and 400mL deionized water into a 3-liter stirring container, heat to 50°C under stirring, and dissolve to form soluti...

Abstract

The invention discloses a preparation method for an anti-bacteria pure cotton fabric. The preparation method comprises the following steps that 4-17 g of sulfonated poly ether ether ketone, 7-19 g of hydrogen atom donor polymers, 1.8-11.3 wt% of cross-linking agents, an appropriate amount of acetic acid for regulating the pH value of finishing liquor to 2-5 and the balance deionized water are mixed into 1 kg of solutions; a pure cotton fabric is coated with the finishing liquor on a flat screen printing machine; the fabric is pre-dried in a drying oven with the temperature of 100 DEG C for 10-25 min; the fabric is baked in a baking machine with the temperature of 160 DEG C for 35-80 s; the fabric is coated with foam finishing liquor containing silver salt through a foam finishing method, and then vacuum drying is performed on the fabric; the fabric is placed in an photochemical reactor and radiated with 350-nm ultraviolet light to reduce silver ions to generate silver nanoparticles, and the anti-bacteria pure cotton fabric is prepared. The anti-bacteria pure cotton fabric is soft in handfeel and excellent in anti-bacteria property, overcomes the defect that the anti-bacteria property gradually becomes worse due to problems such as silver ion dispersion and migration of a traditional nano-silver anti-bacteria fabric and can be applied to the field of anti-bacteria protection suits.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial pure cotton fabric, belonging to the field of functional textiles. Background technique [0002] In daily life, people will inevitably come into contact with various microorganisms. These microorganisms will rapidly grow and reproduce in a suitable environment, spread diseases, pollute the environment, and affect people's physical and mental health. Therefore, antibacterial substances are widely used Used in daily textiles such as non-woven fabrics, underwear, footwear, towels, bedding and decorative fabrics. With the development of society, people are more and more fond of antibacterial functional clothing, and their requirements are getting higher and higher. The antibacterial agents used must not only be efficient and safe, but also environmentally friendly, efficient, durable and safe. Development is getting more and more attention. Therefore, it is very meaningful to study the ant...
