Flame retardant fiber production process

There are fire-retardant fiber manufacturing coating, blending , and graft copolymerization modification method and core-sheath composite spinning method . Coating method is a fiber made ??of a flame retardant used in the production process or its physical adsorption or chemical binding , the flame attached to the flame retardant fabric to achieve the purpose of the method . However, moisture can lead to physical adsorption , toxicity and other issues, it will cause fabrics chemisorption strength decreased , feel hard and other defects. And this fire-retardant treatment method limited scope depends on the skills and finishing plant , the treatment effect instability, poor durability . This method is generally used for natural fiber fabrics and synthetic blended fabric with flame processing, can also be used for pure polyester , polyacrylonitrile fabric processing , but the application is not common. Blending the spinning slice that is added during the manufacturing process or the flame retardant was added to a melt spinning method to obtain flame retardant fiber . To produce a flame retardant polypropylene fiber , the addition of flame retardants , there are two methods : ① Full Granulation : the polypropylene , flame retardants , stabilizers were blended , and extrusion granulation . Pellets with this spinning , flame retardant properties can be obtained with polypropylene fibers. ② masterbatch method: flame retardants, carrier , stabilizer were blended granulation, which is masterbatch pellets . Spinning , the polypropylene masterbatch certain proportion slices mixed, and spun to obtain a flame retardant polypropylene fiber . This method uses the more common , reducing the spinning temperature , to improve the spinnability of the polypropylene , the yarn strength, elongation qualities such little effect . Copolymerization polymer that is added during polymerization of the monomer in a flame retardant obtained by copolymerizing a molecular chain containing fire retardant chemicals unit slice spinning method . Modified polymers using this method , durable flame retardancy . This method is mainly used for addition polymerization type ( polyacrylonitrile ) and polycondensation type ( polyester, polyamide ) . Graft modification method is to use radiant heat , high-energy electron beam or chemical initiator of the fiber and flame retardant monomer graft copolymerization, to obtain effective and lasting flame retardant modified method . Fire retardant and flame retardant modified fiber grafting monomer graft copolymerization retardant elements and relevant parts . The flame-retardant sheath-core composite spinning method for modifying the application is not common , primarily because of the need complicated spinning apparatus . In recent years, composite flame retardant polyester fiber spinning method , the use of skin - core structure , that is, or add a flame retardant copolymer polyester core common polyester composite spun from the cortex . This is to prevent premature decomposition of halogenated flame retardants affect hydrogen halide leave the flame retardant effect, and also prevents certain shortcomings of phosphorus flame retardants are not high temperature , but also to maintain the original appearance of the fibers , whiteness and dyeability .

Anti-static clothing production process and the cleaning process

Antistatic coveralls antistatic function can be divided by vertical bars and squares two kinds . antistatic fabric coveralls divided into a variety of styles , our company can according to customer needs ; anti-static coveralls press cloth points: 100D and 75D, 68D. During 100D more commonly used . Anti-static coveralls by color : You can have a variety of options , specific to our fabric version is based . During longer see the white and blue . My company produces anti- static clothing, use a dedicated anti-static clean fabric production. This selection of special polyester filament fabrics , warp or weft woven inlay Japanese Kanebo Belltron9R series of conductive fibers . An efficient, permanent anti-static , dust-proof function, thin slip , textured clear characteristics. The process used in the production of garments sewing machine dedicated package , useful, reduce particulate attack. Clean Velcro prevents hair loss due to environmental pollution . According level needed to supply different styles and use conductive fibers sewn to make clothing a somewhat adhere electrical continuity ; sleeves and pants for the unique bi-level programming , the use of conductive or antistatic inner rib, then meet the high-grade dust-free environment needs.

Made of high quality polyester continuous fiber fabrics, both senior clean clothes of particular needs . ( Dust resistance, filtration, comfort, durability , adhesion is difficult , easy to wear resistance )
Imports of high-quality conductive wire to ensure excellent anti -static function commodities .
Special polyester filament thread sewing machines, sewing techniques and technologies together .
Be the first to import cleaning equipment, 10 , 100 clean room to be able to supply customers require the most severe effect .
Preemptive testing equipment and methods , severe quality processing system to ensure that every product has high quality .
Barcode processing system to track the use of clothes situation .
Supply of cleaning work clothes with effect applied to various levels of clean room .

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.
