Blocking fuel surface features is how to achieve
Nowadays , all kinds of functional fabrics applications become more frequent , especially in fire-retardant fabric is the best choice for many manufacturers overalls . Especially those working environment is more severe , more need to make effective security protection work. Especially when the fire broke out , if dressed in protective clothing, Fire
resistant fabric , then you can effectively protect skin burns, give yourself a more personal protection , you can better help themselves escape from the fire scene . So, in the end is how the fabric to achieve the necessary heat barrier it ?
1 Clothing accessories material selection
Protective clothing as the main component , related accessories carefully selected choice of material is required , including buttons, zippers , etc. that can not easily deformed , and the best selection of strong heat-resistant material type.
Two metal parts and needs to be avoided physical contact
Designed for Protective Fabric clothing in the time , we must note that is above the metal parts and the body must not be in direct contact with, or occurring in the actual situation can easily lead to unexpected appears.
3 main ingredients in flame-retardant materials
Related to the choice of ingredients should be cause enough caution , you must be fire-retardant materials as feedstock type , the corresponding indicator measures should also be strict requirements, such as reflective tape inverse reflection coefficient are required to meet the basic requirements
Introduction of view, the role of the fabric is worthy of recognition , not only conducive to the normal physiological requirements, but also to meet the basic needs of wear , in size relative is very loose and will not cause any normal job obstacles . Note that the grasp of the clothing on the gap should be maintained at a reasonable scale, the intensity must not affect the garment is based .

Antistatic fabric widely used in the family
In the field of home textiles , synthetic fibers make up the shortage of natural fibers are widely used, but its poor moisture absorption , easy to accumulate static electricity, woven into textiles and easy cleaning , contamination , poor ventilation , can also cause severe electric shock , and even cause fire. So people want to have antistatic textiles , namely fabric itself can eliminate static electricity. Antistatic currently two ways: First, antistatic fabric finishing, finishing in antistatic finishing agent used in the introduction of the fiber surface hydrophilic film layer can improve the fabric moisture absorption, reduce the friction coefficient and the surface resistivity ; second conductive fiber fibers first , and then the electrically conductive fibers woven into the fabric . antistatic fabric in bedding, curtains and other textile products already have good application.
Anti-static fabric processing methods
So if in a dry environment or after repeated washing, processing effect or not durable or not significant , usually in ordinary clothing with fabric applications . The third method is only sustainable and efficient solution to the problem of static electricity textiles , it is widely used in the production of anti -static clothing. Antistatic finishing agent for fabric finishing . The antistatic fabric types and include : Antistatic silk ( conductive silk ) and anti-static clean fabric, anti-static tc fabric, anti-static tr fabric, anti-static cvc fabric, anti-static cotton fabrics.
Anti-static fabric processing methods usually about several :
First, antistatic finishing agent for fabric finishing
Second , in order to improve the fabric for the purpose of moisture grafted fibers , hydrophilic fibers blended and interwoven
Third, blended or woven conductive fibers embedded ; former mechanism of action are two types of methods to improve the fabric moisture regain , reducing insulation, accelerate static leakage.

Measures to prevent the accumulation of flammable overalls
Measures to prevent the accumulation of flammable clothing, a certain way through the conductive object as soon as the combustible charge, it is dispersed or leak out. Therefore, the flame retardant fabric clothing should be selected with good conductive fiber fabrics, flame retardant fabrics currently used mainly in the following three kinds.
1 the effect of humidity using anti-flammable dependence. Finishing by an anti-flammable, which is added in the spinning hydrophilic polymer (surfactant), the fabric easy to absorb moisture from the air, reduce the sheet resistance, reducing the accumulation of flammable, combustible timely release of the body.
(2) the use of conductive fibers. The fiber material is added anti-flammable agents and carbon black particles to become conductive fibers by blending, and cross, cross knitting, weaving or embedded woven methods to improve the conductivity of the fiber or fabric, flame retardant fabric generated, zgm09zd achieve charge dissipation to prevent accumulation of flammable.
3 in the amount of fibers mixed metal fiber blended fabric, the kind of fabric, good stability, resistance to washing.
Special labor protection supplies are included in the directory of the "flame-retardant overalls," is to prevent the accumulation of flammable overalls, flame retardant fabric for the fabric while sewing, suitable for wearing a fire or explosion hazard. Retardant fabric used mainly in the textile production process, the substantially homogeneously mixed with other interval or the whole or parts of metal or a conductive organic material or a flame retardant synthetic fibers, or a mixture interwoven . Classification
Any use as overalls, fire and explosion hazards in the workplace wearing clean overalls, flame retardant overalls, fire retardant cardigans, are included in the scope of management safety signs.
Retardant overalls technical requirements including structural, flame retardant, high strength three aspects.
Overalls production structure directly affect the flame retardant effect, therefore, the structural design of fire-retardant overalls must ensure that:
1. Overalls generally not use metal attachments, you must use metal buttons, zippers, should strictly ensure that when wearing metal accessories are not directly exposed to avoid discharge sparks, fire, explosion.
2. Overalls should all use Flame retardant fabric, do not use lining. You must use the lining (pocket, reinforced cloth, etc.), the exposed area should be less than full lining retardant clothing exposed area within less than 20%; winter clothes or other special requirements for flame-retardant clothing, lining exposed within the area over all retardant clothing exposed area of ??20%, should be made of the mask with detachable lining.
Qualified retardant overalls, each product must be marked with manufacturer's name (or factory mark), site, product names, trademarks, shape specifications, product grade, date of production; Each package shall specify the number, the product name, number type, grade, production units, date of manufacture, together with the product instructions. The product specification shall be flame retardant grade level, A grade or B grade.

Flame retardant properties overalls have some durability, so choose retardant overalls also need to pollution in the workplace determined by washing requirements, select the appropriate level of fire-retardant overalls. Retardant overalls for fire and explosion sites, so should normally choose to have flame retardant overalls performance for workers to provide more reliable protection. Operatives and similar types of work stations using fire-retardant overalls, should also have the effect of anti-oil. Cotton clothing made of the effect of preventing flammable, but not necessarily to achieve the required fire overalls single electric charge amount is less than 0.6μC clothing requirements, especially in the washing, due to the selection of detergents and other reasons, the effect which prevents flammable will decline, therefore, the choice of cotton fabric, flame retardant overalls, particularly in the northern dry areas, we must be careful.

How to buy a real anti-static clothing
Usual Antistatic
fabric , there will be black conductive wire, but there are true and false , because the high cost of anti-static cloth , some markets will use the usual polyester fabric printing black line , and then soaked in anti-static solution, the cloth has a certain period of time antistatic effect.
About a lot of procurement , the procurement of high quality anti-static clothing , is a vexing problem . First, I do not know how to detect its anti-static clothing , the second is to pick up a anti-static clothing , in the acquisition of the division of qualified, but with some time, only to find that their products do not have the anti-static function, and normally there is no difference of goods . Take anti-static work clothes , in the time of purchase , point to point resistance measurement device to reach the national standard, however , clothes washing several times in the future , its point resistance measurement , it was found , is now inconsistent with national anti-static service testing specifications. The main problem is that, in the purchase of this anti-static clothing after midnight, this fabric has anti-static clothing with antistatic agents disseminated over , so whatever point resistance tests can reach national norms.
Detailed distinction , you can wash the cloth , wash a few times , if it is false, it is not washed off antistatic liquid antistatic , if it is electrically conductive wire , the role is probably the same, detailed parameters are usually is the appearance of resistance 10 ^ 6 - 10 ^ 9 ohms.
So when in the acquisition of goods , reminds us that the quality of goods is vital, not only to offer goods cheaper Fig . Quotations are not crucial , the key lies in the quality of goods is not reached to prevent static.

fabric clothing in several commonly used anti-static cloth fabric
Many types of anti-static fabric , summed up in roughly three types:
The first one is the fabric used for the resin antistatic agent tidy , through baptism , drying and melting the surface adhering to the synthetic fiber fabric , the fabric has some antistatic effect . This method is now used only for civilian clothing to beat clothes discharge , pollution, dust and other static representation suck .
The second is in the polyester polymer is added internally or damask antistatic agents , surfactants such as sulfonate or the introduction of a third monomer to obtain a durable antistatic fiber . Since most of the added base case antistatic agent can react to a surfactant decomposition , thus washing the fabric tidy or alkaline scrubbing agent is hanged , prevent the impact of the antistatic effect , so that the fiber suitable for production of clean clothes , sterile clothes , can also be used for civilian garments.
The third method is usually mixed with conductive fiber fabric , such as anti-static fabric not address the environmental impact , is now widely accepted and recognized under this anti-static fabric antistatic function and the type of conductive fibers and conductive component distribution in the fiber can be divided into conductive components are together , cover the conductive components , conductive or conductive component of complex and hybrid type of four . If you select cover type conductive fibers , particularly coating method is up penetration , because of its conductive components in the fiber surface , than simple drop, thus affecting the anti-static function .
In all conductive fibers , in addition to stainless steel fibers , the other can be directly used for fabric monofilament or multifilament . Stainless steel fiber has excellent electrical conductivity , thermal conductivity , abrasion resistance and other characteristics of electromagnetic waves can be reflected . In the petrochemical , electronics, electricity and military and other work has been widely used , but the stainless steel fibers in the textile equipment processing more messy , by the impact. Rich in carbon, graphite, and other conductive component composite conductive fiber filament can be directly used for weaving , the warp yarns across a medium distance (eg about 1.5cm ) embedded in a conductive yarn , excellent antistatic effect can be obtained , was used for weaving cloth, the best anti-static conductive fibers.
