Functional finishing of knitted fabrics

Functional finishing of knitted fabrics
Specific Fabric Knowledge Sharing

 

 

The waterproof function of knitted products can be achieved through coating finishing and immersion rolling methods. Among them, fluorinated waterproofing agents can endow the finished fabric with excellent waterproof performance, but fluorinated polymers can have toxic effects on human health and the environment. Therefore, designing and developing environmentally friendly fluorine free waterproof finishing agents has become an inevitable trend in the development of waterproof finishing

 

 

water proof finish

 

 

The anti UV function of knitted products can be achieved through immersion adsorption and coating processing methods, which cover the surface of the fabric with a layer of substance with anti UV function; Excellent UV shielding performance, widely used as UV shielding agents in fabrics and various UV resistant products

 

UV resistant finishing

 

 

Chemical modification of fabrics, coating and finishing of fabric surfaces, and embedding conductive fibers into fabrics have significant advantages in durability and functional diversity of anti-static effects. Anti static finishing is mainly achieved by introducing hydrophilic groups or adding conductive fillers on the surface of knitted fabrics to improve their surface hydrophilicity, reduce the generation of static electricity, or increase the divergence of static electricity, thereby reducing the accumulation of charges on the surface of knitted fabrics and reducing static electricity

 

Antistatic finishing

 

antibacterial finish

 

Antibacterial finishing cannot be separated from the use of antibacterial agents, which can be divided into three categories: organic antibacterial agents, inorganic antibacterial agents, and natural antibacterial agents; Antibacterial functional finishing mainly includes four functional finishing methods: surface coating method, immersion rolling method, grafting method, and microcapsule method

 

Flame retardant finishing

 

The common flame retardant finishing methods for fabrics include impregnation, chemical modification, and coating finishing. Among them, coating finishing has low cost and wide application. In addition, with green environmental protection becoming the mainstream of research, smoke suppression and toxin reduction are the next research directions for environmental flame retardancy, such as environmentally friendly carbon based and biomass flame retardants

 

crease-resist finish

 

Anti wrinkle finishing agents are the key to anti wrinkle finishing. Traditional anti wrinkle finishing agents contain formaldehyde, which may affect human health. Currently, formaldehyde free anti wrinkle finishing agents are more popular

 

Far infrared sorting

 

By using far-infrared finishing agents, knitted products can emit far-infrared radiation that is easily absorbed by the human body, accelerate blood circulation, enhance metabolism, and have a certain degree of warmth retention. In addition, low-temperature far-infrared oxidation; Nanocomposites of graphene and novel graphene oxide materials, followed by immersion rolling treatment, can integrate reduced graphene oxide zirconium titanium oxide composite materials into cotton fabrics
Producing cotton textiles with high far-infrared emission performance, low cost, and strong practicality
