Embodiment 1

[0019] Formula: nano zinc oxide, particle size 20-40nm, dosage 5%; oligomeric sodium acrylate, viscosity 5Pa.S, dosage 6%; diamino silicone oil, ammonia value 0.3, dosage 20%; water, dosage 69%.

[0020] Preparation process: Dissolve oligomeric sodium acrylate in 20 parts of water, add nano-zinc oxide powder under stirring, then add diamino silicone oil, and continue stirring evenly to form a type of nano-functional finishing agent.

[0021] Application process: the test fabric is a printed cotton towel; the dosage of nano-functional finishing agent is 5% (owf) of the relative fabric weight; the process flow, the printed cotton towel is dipped and rolled twice, the rolling rate is 100%, and then dried with hot air Dry at a temperature of 90°C-100°C, and then cut, sew, and package to make printed cotton towels with antibacterial, deodorant, health care, and skin care functions.

Embodiment 2

[0023] Formula: nano-titanium dioxide, the particle size is 10-20nm, the dosage is 3%; the dosage of ammonium polyacrylate is 5 percent; the dosage of hydrophilic silicone oil is 18 percent; the dosage of polyacrylate adhesive is 20 percent; the dosage of water is 54 percent.

[0024] Preparation process: first dissolve ammonium polyacrylate in 20 parts of water, add nano-titanium dioxide powder under stirring, then add hydrophilic silicone oil and polyacrylate adhesive, stir well, add remaining water, grind twice with colloid mill Serve as a type of nano functional finishing agent.

[0025] Applied Technology: Trial Fabrics, 21 s ×21 s 60×58 36″ bleached pure cotton plain cloth; the amount of nano-functional finishing agent is 3.5% (owf) relative to the weight of the fabric; the bleached pure cotton plain cloth is subjected to two dipping and two rolling, at 30°C, and the rolling rate is 80%-85 % and then dried at 85°C-105°C and baked at 150°C-190°C, then inspected and pac...

Embodiment 3

[0027] Formula: nano-titanium dioxide, particle size 10-20nm, dosage 1.5%, nano-zinc oxide, particle size 50-60nm, dosage 3%, Span-80, dosage 3%, Tween-80, dosage 2%, flat Add 0-15, the dosage is 1.5%; polyurethane adhesive, the dosage is 20%; water, the dosage is 69%.

[0028] Preparation process: Dissolve Span-80, Tween-80, and Pingpingjia 0-15 in 30 parts of water, add nano-titanium dioxide and nano-zinc oxide powder under stirring, grind twice with a colloid mill, and filter to form a model Nano functional finishing agent.

[0029] Application process: the test fabric is polyester-cotton knitted fabric; the dosage of nano-functional finishing agent is 8% (owf) relative to the weight of the fabric. First soak the polyester-cotton knitted fabric (20°C-60°C, 0.5-2 hours) and then dehydrate it in a centrifuge (so that the amount of liquid is 80%-100% of the cloth weight) and then dry it with hot air at a temperature of 85°C-110 ℃, and then made into products through conventi...

Abstract

The invention relates to a preparation method of a textile nano-functional finishing agent mainly containing inorganic nano-materials for producing antibacterial, deodorant, health-care and skin-care functional textiles. The inorganic nano-materials are dispersed in an aqueous solution of a surfactant under stirring conditions, Stir continuously to form a fluid colloid, then add auxiliary components, and continue to stir evenly to make a nano-functional finishing agent; the inorganic nano-material is nano-zinc oxide, nano-titanium dioxide or a mixture of the two, and its content is 0.01% by weight of the finishing agent-30 %, the rest are auxiliary ingredients, and the total weight percentage of the finished product is 100%; the nano-functional finishing agent is processed through dipping, rolling, baking, baking process steps or directly spraying the raw materials of textiles to make it antibacterial, deodorant , health care and skin care functions are used to prepare fabrics. The method has the advantages of simple production process, reasonable raw materials and formula, good product performance, and is an ideal fabric processing technology for disease prevention and health care.

Description

Technical field: [0001] The invention relates to a preparation method of a textile nano functional finishing agent mainly containing inorganic nano materials for producing antibacterial, antibacterial deodorant, antibacterial health care or antibacterial skin care functional textiles, and its international patent classification number is D06M13 / 000. technical background: [0002] Green consumption promotes the research and development of green functional textiles. Because nano-zinc oxide and nano-titanium dioxide are non-toxic and environmentally friendly, they open up a new way for the development of green functional textiles. Although there are many studies on the preparation methods of nano-zinc oxide, the research on its application technology is relatively lagging behind; especially the research on textile finishing is even rarer. In view of the fact that the technical terminology of nanomaterials for textile finishing has not yet been unified, the finishing agent prep...
