Three methods of FR finishing:
1) exhaust combustion method: fire retardant and cellulosic fibers integrated with ionic bond or covalently bond, which makes it not dissolved in the durability to get the durable flame retardant function.
2) liquid method: add the flame retardant to the spinning solution directly.
3) copolymerization method: add the flame retardant to the polymer chain segments, which can makes the fabric washable, resistance to bleaching , perspiration resistance, not absorbed by skin.
The after-treatment FR fabric produced by Xinxiang Yulong Textile Co. Ltd mainly use organic phosphorus flame retardant to do the fire retardant treatment.
1, THPC (Tetrakisphosphonium chloride)
1) white color, can be solubled in the crystalline compounds of water and lower alcohol.
2) aqueous solution of THPC is acidic
3) react with amines, amides, carboxylic acid，alcohols,
4) similar reaction with fiber
Finishing technology: immerse finising liquid → drying（80-90℃）baking, washing, drying
2, The composition of Pyrovatex CP liquid: fire retardant, buffer agent, stabilizer, catalyst, softening agent, fixer and so on.
Padding(CP) →padding(TMM) →dry(85℃) →baking（160℃） →alkali wash
3, cotton/poly blended fabric FR finishing technology: Polyester component with three (2, 3 two bromine propyl) phosphonic acid ester (TDBPP), cotton component with THPC, these two finishing agent can be finished with bath pad , the requirement is that two finishing agent is consistency, can fixed under the same conditions.
Technological process: padding →dry →thermosol（180~200℃） →soaping（70~80℃）→washing→dry

How many sort divided in FR fabric based on FR effect sort?
FR fabric divided in fiber FR and after treatment FR, for the latter one ,it's divided to one time FR and forever FR. The fiber FR, named forever FR fabric, it is treated on the fabric making preparation stage, mainly using FR fiber weave to gray cloth, which FR effect is never ever changeable. It 's snarls , carbonization while facing the fire, and distinguished while away from the fire, non-melt and non-smoking, will not cause second fire disaster, usually it used on FR clothing material. One time FR fabric is normal fabric treated on the after dyeing treatment, which have the big problem of the FR effect will vanish or decline after one time washing, generally applied in seldom washing products, such as hotel curtain. Durable FR fabric usually using Proban production craft, what agent used is one durable after treatment FR agent applied on cotton fiber and other blended fiber. Its main character is that after using this agent treated, the fabric will have great FR effect after washing 50 times. This three kind of FR fabric 's original FR property is no such big difference, just after one time washing, the one-time FR fabric's FR property will vanish. By YULONG FR tex

What are the fabric after-finishing technologies?
After-finishing is a technical treatment which makes the fabric have excellent performance in color, form( bright, suede, stiff and smooth) and practical effect( waterproof, no felting, non-ironing, no decay, burning resistance). Fabric after-finishing is a process to improve the fabric's surface and hand-feeling and strength the fabric performance. After-finishing divided into physical/mechanical finishing and chemical finishing. The existing after-finishing technologies have whitening, sizing, tentering, preshrinking, calender, electro-optics, corrugated, sanded, softening, liquid ammonia finishing,,wrinkle proofing, water repellent, anti static finishing, soil release finish, moth-proof finish, rot proof finishing, fire retardant finishing, weighting finishing, deweighting finishing, coating finishing, cook, wash, milling, fluff, shearing, blowing, pressing, prevent anti-felting finishing, washing, sand washing, stone mill, antibacterial deodorization finishing and so on. The fabric after finishing can improve the clothing inner performance, makes clothing more new functions. Napping, sanding Finishing makes the fabric fluffy, enhance the fabric heat retention property, moisture retention. Calendering, lightning and singeing finish makes the surface fabric less villus, increase the fabric anti-fuzzing and piling property. Shrinking, liquid ammonia, setting makes the fabric stability, lower the fabric shrinkage rate. Soft, liquid ammonia finishing perfect the fabric hand felling, makes the clothing more comfort. The waterproof and moisture permeating finishing makes the clothing more comfort in rainy days. Water repellent and soil release finish makes the clothing more clean. The anti-static finishing make the clothing escape the static, and makes more security, clean and tidy. Fire retardant finishing can effectively prevent the flame spread and maintain the fabric raw performance, safe and reliable, air and water vapor permeability, soft handle and wearing comfortable.

What is untreated fabric called?
Untreated fabric is typically referred to as "raw fabric" or "unfinished fabric." This term is used to describe fabric that has not undergone any additional processes such as dyeing, printing, or finishing.

What is FR fabric?
FR fabric is a kind of fabric even it is lighted,it will be extingished by itself after moved from the fire within the prescribed period of time.It is widely used in garments .To judge the rate of burning of the fabric:the textile in accordance with the provisions of the method of contact with the flame for a certain period of time, remove the flame, the fabric burning and smoldering time and fabric damage length determine the fabric flame retardant performance. The shorter the time of burning and smoldering, the lower the damage length, the better the flame resistance of the fabric.There are mainly 2kinds of testing methods. 1,Horizontal burning2,Vertical burningEuropean standard : EN11611(EN470), EN11612(EN531), EN14116(EN533), etcAmerican standard:16CFR 1610There are mainly 2 kinds of FR fabric used for garments.1)inherently fire retardant fabric2)FR treated fabricinherently fire retardant fabricaramid fabricmodacrylic fabricmodacrylic /cotton fabric FR treated fabricFR 100% cotton fabricFR cotton/nylon (C/N ) fabricFR cotton/polyester fabric
What is the diesel aftertreatment system used in the 2011 prostar with cummins isx motor has Navistar gone in for DEF against the their cooled-egr technology for these vehicles?
They use the Cummins aftertreatment system with the DPF, DEF doser, and SCR on their vehicles equipped with Cummins engines. After the failure of the MaxxForce aftertreatment system to meet EPA and CARB requirements, they've gone to a full aftertreatment system with DEF and an SCR for the MaxxForce engines, as well.
What are the classifications of textile FR finishing?
Methods of fiber and textile FR finishing can approximately be divided into precursor fiber flame-retardant modification and Fr treatment. First is precursor fiber flame-retardant modification, the flame retardant acrylic and polyester, adopt copolymerization process, the flame retardant gang together with the macromolecular chain, which makes durable FR performance. This copolymerization process is is suitable for polymer with no polar radical especially, for example, the polypropylene. Second is the textile Fr treatment, can be classified into pdc process, net absorption method, organic solvent method, coating method and the spraying method. In the process of the cellulose fiber FR treatment, Pyrovatex CP, TH2PC, proban and Banf lam all belong to pdc process. The FR treatment for vinylon also adopts this method. Rarely adopt the organic solvent method, because there are some problems with security. Coating method will makes the textile harden, usually used for tarpaulin or decorative fabric. The polyester fabric can use net absorption method, there is not enough experience for combination fabric FR treatment, but in our country, the 87 FR poly/cotton FR fabric researched by quartermaster equipment institute have accumulated several yeas Industrial production experience, the performance excelled American Leb lanc company congeneric Products. The textile burning is harmful reactions once achieves a certain extent, so the flame retardant intimately connected to heat proof. In addition, furnaceman workwear also need the radiant heat resistant function, fireman workear should have water poof function, petrochemical Jobs workwear shoud have anti-static function. The workers work in a certain environment wotj safety workwear, which ask for the workwear has the function of safe application performance and environmental safety performance, In order to improve the effectiveness, the workwear should have function performance and comfortable performance. Obviously, it is objective needed to make the FR textile more functions.
