Introduction of anti - acid and alkali fabrics and flame - retardant fabrics

Introduction of anti - acid and alkali fabrics and flame - retardant fabrics
What is anti-acid and alkali fabric:
Anti-acid and alkali fabric is mainly used to prevent acid, alkali and other chemicals on the human body injury, prolong the acid from the clothing surface to penetrate the skin time, so that the acid in the clothing surface is not attached, clothing in the acid erosion after a strong change Small and can withstand strong acid pressure.
Anti-acid and alkali performance of 97.5%, higher than the national anti-acid performance standards 90%, in line with gb12012-89 anti-acid work clothes requirements. Mainly used in chemical industry, metallurgy, mineral, geological, electroplating, printing and dyeing, paper and other industries and acid and alkali, chemical contact with the type of protective clothing fabric.
Anti-acid and alkali fabric has a good breathable performance and the case of acid and alkali, oil and water impermeable, with a long acid resistance, acid pressure and low dip rate of good anti-acid and alkali performance, the practitioners have a very good protection The Meet the en13034 "protective clothing - anti-chemical liquid" requirements.
Anti-acid and alkali fabric classification:
1, ordinary anti-acid: in the fabric when the time to add anti-acid technology, the surface is no different with ordinary fabrics. Suitable for general acid-base environment.
2, severe anti-acid: in the general anti-acid and alkali fabric on the basis of the coating treatment, a strong anti-acid function. Suitable for high concentration of acid and alkali environment.
Classification of flame retardant fabrics
Usually we imagine the flame-retardant fabric, in everyone's impression is not burning, but really is not, the flame retardant cloth is not no fire, just leave the flame immediately after the off. There are corresponding flame retardant standards, such as: en470- 1, en531, en532, nfpa2112, nfpa70e and so on.
Flame retardant fabric Fibers flame retardant and finishing flame retardant two, finishing flame retardant is divided into two kinds of disposable and durable flame retardant.
Fiber flame retardant, also known as permanent flame-retardant fabric, is done in the entire pre-fabric processing work, mainly the use of flame-retardant fibers woven into the fabric of its flame retardant effect is permanent, and generally can be maintained to wash more than 50 times , Any good washing effect, in particular the use of the flame-retardant yarn polypropylene (polyacrylic, commonly known as acrylic), the case of fire that is crimped, carbonized, the fire is a departure is extinguished, do not drop no black smoke, Produce a second fire. It is usually used for clothing fabrics.
Disposable flame retardant fabric is a common fabric in the latter part of the dyeing and finishing through the flame retardant treatment, its biggest drawback is that after the flame retardant effect disappeared or significantly decline, usually we apply in some occasions the number of washing, such as Hotel curtains and so on.
Durable flame-retardant fabrics are usually "proban" production process, the use of flame retardants is a cotton fiber and its blended fabric durability finishing flame retardant, its main feature is the use of this After the flame retardant is produced, the fabric can have a good flame retardant capacity within 50 times of washing.
Three of the initial flame-retardant performance is not much difference, but after washing a one-time flame retardant fabric flame retardant performance completely disappeared.
