Fabric Introduction: Acid And Alkali Resistant Fabric And Flame Retardant Fabric

< p > < strong > what is < a href= "http://www.91se91.com/news/" > acid and alkali resistant fabric < /a >: < /strong > /p >

< p > acid and alkali resistant fabrics are mainly used to prevent acid, alkali and other chemicals from hurting the human body, and extend the time when the acid permeates the skin from < a href= "http://www.91se91.com/" target= "_blank" > clothing < /a >, so that the acid liquid is not adhered to the surface of the garment, and the clothing changes little after the acid erosion, and it can withstand the strong acid pressure.

< /p >

< p > acid and alkali resistance reached 97.5%, higher than the national acid resistance standard 90%, meeting the requirements of GB12012-89 acid proof work clothes.

It is mainly used in chemical, metallurgical, mineral, geological, electroplating, printing and dyeing, paper making and other industries, as well as acid-base and chemical contact work to make protective clothing fabrics.

< /p >

< p > acid and alkali resistant fabric has good air permeability and is not permeable in acid base solution and oil and water. It has long acid resistance, high acid resistance and low leaching rate. It has good protection function for employees.

Conform to the requirements of EN13034 "protective clothing - chemical liquid".

< p > < strong > classification of acid and alkali resistant fabrics: < /strong > /p >

< p > 1, common acid and alkali protection: when the fabric is made, the anti acid and alkali technology is added, and the surface is not different from the ordinary fabric.

Suitable for general acid-base environment.

< /p >

< p > 2, severe acid and alkali prevention: coating on the basis of common acid and alkali resistant fabrics has strong anti acid and alkali function.

Suitable for high concentration acid-base environment.

< p > < strong > flame retardant < a href= > http://www.91se91.com/news/index_c.asp > > fabric > /a > classification < /strong > /p >

< p > usually we imagine the flame retardant fabric, which is not burning in the impression of everyone, but actually it is not. The flame retardant cloth is not not fired, but just extinguished immediately after leaving the flame. There are corresponding flame retardant standards, such as: EN470-1, EN531, EN532, NFPA2112, NFPA70E and so on.

< /p >

< p > flame retardant fabric is divided into two types: flame retardant and finishing flame retardant. After finishing, flame retardant is divided into two types: disposable and durable flame retardant.

< /p >

< p > flame retardant fiber, also known as permanent flame retardant fabric, is done in the early stage of the whole cloth making process. The main effect is to use flame retardant fiber to form grey cloth. Its flame retardant effect is permanent. It can usually maintain more than 50 times washing and has good washing effect. In particular, the flame retardant yarn is polypropylene (Polyacrylic, commonly known as acrylic), which is curled and carbonized in the presence of fire. When the fire source is left, it does not produce black smoke and does not produce two fires.

It is usually used for clothing fabrics.

< /p >

< p > disposable a href= "http://www.91se91.com" > flame retardant fabric > /a > ordinary fabric is treated by flame retardants in the latter stage of dyeing and finishing. Its biggest drawback is that after washing, the flame retardant effect is disappearing or obviously declining. Usually we are used in some occasions with less washing times, such as hotel curtains and so on.

< /p >

< p > durable flame retardant fabrics usually use the "PROBAN" production process. The flame retardant used is a kind of durable finishing flame retardant for cotton fiber and its mixture of a href= "http://www.91se91.com/" target= "_blank" > textile > /a ". Its main characteristic is that after using this flame retardant, after finishing production, the fabric can have good flame retardancy within 50 times of washing.

< /p >

The initial flame retardant properties of < p > three are not very different, but the flame-retardant properties of disposable flame retardant fabrics completely disappear after washing.
