The fabric people make clothes has evolved from the most primitive bark and animal

skin to silk, cotton, plants and other silk, cloth and so on. With the

development of industry, wool is made into woolen cloth, serge and so on. Under the

rise of the chemical industry and the development of processing technology,

chemical fiber, blended and other products have been added, and a variety of imitation

silk, imitation cotton, imitation wool and other products have also appeared.

With the passage of time, the fabric has gradually evolved a variety of new functions

under the needs of people. The most practical of these are the following six.

water repellent - Repellent

Concept: Water repellent finishing, also known as breathable waterproof finishing,

that is, chemical water repellent treatment, so that the surface tension of the fiber

is reduced, resulting in water droplets can not wet the surface of the process.

Application: Raincoat, travel bag and other waterproof materials.

Function: simple treatment, low price, good durability, and after water repellent

treatment of the fabric can still maintain its air permeability, mainly used in cotton,

hemp fabrics, can also be used in silk and synthetic fabrics. The water-repellent

finishing effect of the fabric is also related to the fabric structure.

oil-repellenting textiles

Concept: oil-repellent finishing, the process of treating fabric with oil-repellent finishing

agent to form an oil-repellent surface on the fiber.

Application: high-grade raincoat, special clothing material.

Function: After finishing, the oil-repellent surface tension of the fabric is lower than the

surface tension of various oils, so that the oil is beaded on the fabric and not easy to

penetrate into the fabric, resulting in the oil-repellent effect, and the oil-repellent fabric

has both water repellent and good permeability.

Antistatic antistaticing

Concept: Antistatic finishing is the process of applying chemical agents to the surface of

the fiber to increase its surface hydrophilicity to prevent the accumulation of static

electricity on the fiber.

Causes of static electricity: Fibers, yarns or fabrics produce static electricity due to friction

during processing or use.

Function: Improve the hygroscopic property of fiber surface, reduce the surface specific

resistance, and reduce the electrostatic phenomenon of fabric.

Easy soil removal -releaseing

Concept: Easy decontamination finishing is a process that makes the dirt on the surface of

the fabric easy to be removed by general washing methods, and makes the dirt under

the wash not return in the washing process.

Causes of dirt formation: During the wearing process, the fabric forms dirt due to the

absorption of dust and human excrement in the air and contamination. General fabric

surface hydrophilicity is poor, good lipophilicity, washing water is not easy to penetrate

into the fiber gap, but after washing, the dirt suspended in the washing liquid is easy to

re-stain the fiber surface, resulting in re-contamination.

Action: Reduce the surface tension between fiber and water, increase the hydrophilicity

of fiber surface; Increase the antistatic property of the fabric, make the fabric comfortable

to wear, feel soft, but the fabric tear strength decreased.

flame retardant textile flame - retardaning

Concept: Textile after some chemical treatment can not be easily burned in case of fire, or

a fire is extinguished, this treatment process is called flame retardant finishing, also

known as fire protection finishing.

Principle: The decomposition of flame retardants produces non-flammable gas, thus

diluting the flammable gas and playing a role in shielding the air or inhibiting the flame

combustion. Flame retardants or their decomposing substances melt and cover the fiber

death to act as a shield, so that the fiber is not easy to burn or prevent the carbonized

fiber from continuing oxidation.

coating

Concept: Coating finish is the process of coating or bonding a layer of polymer material

on the surface of a fabric to give it a unique appearance or function.

Application: anti-down, waterproof and moisture-permeable, light insulation, flame

retardant, conductive, imitation leather and other fabrics.
