What Are The Common Fabric Finishing Process?(3)

In addition to being used in general daily life, textile articles can also improve their application range after some special finishing processes, such as water repellency, flame retardancy, anti-static and stain resistance. These properties of general textiles do not have, but after special finishing methods to obtain, this type of finishing method is called special finishing.

01、Waterproof finishing

According to the different processing methods can be divided into two categories: one is a coating method on the surface of the fabric to impose a layer of water-insoluble continuity of the film, this product and impermeable to water, but also airtight, should not be used as a general apparel products, and is suitable for the production of rain tarpaulin, umbrellas and so on. Another type of finishing method is to change the surface properties of the fibre, so that the hydrophilic surface of the fibre into a hydrophobic, while the fabric between the fibres and yarns are still retained a large number of pores, so that the fabric can maintain breathability, but also is not easy to be wet by the water, suitable for the production of rain and wind clothing fabrics. This breathable waterproof water finishing is also known as water repellent finishing. Water-repellent finishing mainly has the following methods.

02, anti-static finishing

Clothes due to friction with static electricity, often make the skirt adheres to the legs, coat sucked tightly in the underwear, in some explosive places will also be due to static sparks lead to an explosion.

Printing and dyeing finishing process is often used in the durability, external application of static preventive agent. This kind of static electricity preventive agent requirements with durability anti-static effect, does not affect the style of fabrics, does not affect the dyeing and printing of fabrics and the colour of the dyeing and printing of the firmness of the colour, and other additives have compatibility, no odour, non-toxicity to human skin, and so on. Commonly used polymer surfactants, including anionic type, non-ionic type. Cationic type. The above antistatic properties are used to increase the hygroscopicity of the fibre surface to inhibit charge accumulation.

03、Flame retardant finishing

Fabrics after flame-retardant finishing, and can not reach the degree of non-combustible such as asbestos, but can deter the spread of flame, when the source of ignition removed no longer burns, and does not occur residual flame negative combustion. Flame-retardant finishing fabrics can be used in the military sector, industrial transport sector, civil products, such as carpets, curtains, curtains, work clothes, bedding and children's clothing.

Selection of flame retardant, in addition to the flame retardant effect and durability must be considered, but also must pay attention to the strength of the fabric, feel, appearance, fabric dyes and colour fastness of the colour has no adverse effect; on the human skin with or without irritation, flame retardant in the fabric when burning by heat with or without poisonous gas, and other finishing agents, such as co-tolerance.
