Flame retardants commonly used in the classification

A wide variety of flame retardants , classification methods also have a variety . Retardant elements according contained classified into halogen-containing flame retardants, phosphorus-containing flame retardants, nitrogen-containing flame retardants ; according to the use of flame retardants and polymers in the presence of form, divided into additive and response type ; press were divided into non- durable flame retardant fabric flame retardant durable , semi-durable flame retardant , durable flame retardant three kinds ; according to types of compounds can be divided into organic and inorganic flame retardant agent. The following describes the method of classification according to the latter two flame retardants .

Press the durability of the fabric classification

( 1 ) Non- durable flame retardant : flame retardant , also known as temporary , most of the water-soluble ( or emulsion ) inorganic salts. When the first water-soluble flame retardant treatment , drying the impregnated fabric can be used ; also has two bath padding , and the second bath with ammonia or soda , the oxide is deposited on the fabric. This method is simple , cheap, but fabric feel poor, flame-retardant effect after washing fall significantly. Is used in disposable protective clothing .

( 2 ) semi-durable flame retardant : flame retardant fabric manufacturers use this process retardant textile processing capability of 1 to 10 times a mild detergent , but not high temperature soaping . The method has urea phosphate method ( usually called Banflam France ) , urinary phosphate ester method , ammonium a hydroxymethyl ammonium cyanide - A vinegar solution method .

( 3 ) durable flame retardant : inside the fiber by chemical polymerization or condensation reaction of the surface , to form a water-insoluble polymer , generally require more than 30 times washing level . The law mainly Ciba (CP) method and the Proban France . CP France by the Swiss company Ciba creation process is easy to implement the Act , flame-retardant effect is remarkable ; drawback is the larger fabric strength loss , a greater impact on performance apparel . Proban France Aube Lai Yiwei Wilson Limited by British creation, the Act of fabric finishing , flame-retardant effect is good , especially the treated fabric texture and strength retention is unmatched by any other finishing method , but this method is compared with the risk big , serious environmental pollution , thus promoting restricted.

Anti-static fabric garment production practices

Avoid clothing fabric is antistatic fabric static friction in some explosive situations are very dangerous , some of the work environment does not allow static interference , and therefore not allowed to wear clothing with the activities of the human body harmful static electricity. Used in electronics , aviation, aerospace, petroleum, coal and other industries of protective clothing and textile goods, must have good capabilities to eliminate static electricity . Market in recent years on the development of anti-static fabric and functional textile products , mainly in the fabric insert appropriate intervals conductive metal filaments in the spinning process or adding a certain percentage of the metal staple fibers , the use of metal is a good electrical conductor to conduction and eliminate static electricity.
Embedded in the fabric of conductive metal filament process is relatively simple way , but the use of this process to produce an antistatic polyester fabric cards , often due to cling to the outside of the metal filaments of the yarn of the fabric exposed surface unevenness , and the metal filaments are is not complete with fabric dyeing and coloring , so it seriously affects the fabric dyeing and finishing effects, caused by cotton fabric and anti-static and anti-static polyester card CVC anti-static fabric color flower uneven dyeing and finishing process is difficult overcome defects . In comparison, the spinning process at a certain mixing ratio man metal staple fibers , in certain conditions , it is possible to sufficiently uniformly mixed with the ordinary fibers , to achieve the same color . Weaving and spinning with the process that is able to maintain long-term anti-static function , but also a good solution after dyeing and finishing processes appear uneven dyeing color flower problem .

The role of anti-UV fabric knowledge testing standards

Prevent ultraviolet radiation on the human body injury, has been more and more consumers attention. Solar spectrum in the ultraviolet only make textiles fade and brittle, but also allows the body sunburn aging, produce melanin and pigmentation, but also induced more severe cancer, harm to human health.

 Ultraviolet radiation on the human body has drawn increasing attention around the world, Australia and other countries explicitly require students to have sun protection clothing, etc., China has also developed a textile fabric UV standards.

Clariant UV inhibitors to improve the light-colored old textiles, strength, and enhance the textile UV shielding performance, human safety non-toxic, non-irritating to skin allergic reaction, resistance to washing. Especially UV-A, UV-B has good absorption and emission effects, shielding and strong, more than 95% UV excess ultraviolet radiation causes the body to produce skin burns and even skin cancer induced skin diseases, but also to promote cataract formation and reduce the body's immune function.

1) Therefore, in order to protect human avoid excessive ultraviolet radiation, while textiles UV fabric finishing, Clariant anti-UV agents for textile finishing processing to obtain a good anti-ultraviolet UV effects;

2) The anti-UV fabric finishing non-toxic, safe to human body, the skin without stimulation, no allergic reactions, does not affect the fabric color, strength and wet suction vapor permeability;

3) polyester and nylon fabric uv resistant shirts: peach skin Pongee Satin, etc.; surface UV umbrella cloth are: Disi Pongee five satin;

4) anti-UV fabric products, based on customer requirements can be up UPF50 +, UV shielding up to 99% of the human body to form an excellent UV protection, reliable quality, credit guarantee;

5) UV fabric Standard: AS/NZS4399: 1996, UPF good range Protection class 15-24 ,25-39 ,40-50 very good, 50 + excellent;
