Flame retardant for textile use
The flame retardant property of textile flame retardant finishing process can be obtained through three
One is the flame retardant treatment of textiles to achieve the flame retardant purpose, but its flame retardancy will fade or disappear with the increase of time and washing times. For natural fibers such as cotton, linen, wool, can only adopt the method of finishing, namely through adsorption sedimentary flame retardant textile, chemical, textile flame retardants, nonpolar van der Waals force combined with flame retardant textile textile flame retardants and so on.
Another method is direct production of flame retardant fibers, which are permanently flame retardant. Most synthetic fibers such as dacron and veron adopt this method. The third method is to combine these two methods to produce flame retardant textiles according to the actual needs in production. In addition to considering its flame retardancy, flame retardant fabrics also consider the toxicity and melting of flame retardant products to minimize damage to the human body and environment.
The manufacture of flame retardant fiber for flame retardant fiber mainly includes coating method, blending method, copolymerization method and grafting modification method and the core composite spinning method. The coating method is a method for the flame retardant to be attached to the fiber by the combination of the physical adsorption or chemical combination of the flame retardant in the process of making or producing the fiber.
But the physical adsorption is easy to cause hygroscopic, toxicity and so on, chemical adsorption can cause the fabric to fall strongly, the feeling becomes hard and so on. Moreover, this kind of flame retardant method has limited processing scope, which depends on the skill of the finishing plant, the effect is unstable and the durability is poor. This method is commonly used in natural fiber fabric and the flame retardant processing of synthetic fiber blended fabric. It can also be used in the treatment of pure polyester and polyacrylonitrile, but it is not widely used.
The blending method is the method of adding flame retardant or adding flame retardant to the spinning melt. In order to make flame retardant polypropylene fiber as an example, there are two ways to add flame retardants:
Complete granulation method: mix polypropylene, flame retardant and stabilizer, then extrude granule. The polypropylene fiber with flame-retardant properties can be made by spinning with this material.

Diphenyl Isooctyl Phosphate (S141,362, DPOP) Product Overview
Chemical Classification: Diphenyl Isooctyl Phosphate, Diphenyl 2-Ethylhexyl Phosphate
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Is An Excellent Flame Retardant Plasticizer That Can Be Used In Most Industrial Polymers Including PVC And Its Copolymers, Nitrocellulose, Ethylcellulose, Poly Methyl Cellulose Methyl Ester, Polystyrene And The Like. Diphenyl Isooctyl Phosphate (S141,362, DPOP) Are Generally Used In The Manufacture Of Vinyl Sheets, Coated Fabrics, Inks, Plastics, Rubber And Plastic Foamed Organic Sol, Adhesives, Vinyl And Conveyor Belts. Due To Excellent Solubility, Improve The Performance Of Many Formulations. In Addition, It Can Be The Final Product It Offers The Following Range Of Interesting Properties Such As Flame Retardancy, Low Temperature Flexibility, Abrasion Resistance, Grease Resistance, Excellent Light Stability And Outdoor Weather Resistance And Excellent High Screen Welding Performance. Due To Its Excellent Solubility, Diphenyl Isooctyl Phosphate (S141, 362, DPOP), And Then 3 Phr Of Bismuth Oxide And 10-20 Phr Of Aluminum Hydroxide Were Added.
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Can Be Used As An Excellent Flame Retardant Material For Transparent Films. In Some Fire-Resistant Harsh Colored Films, It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To Significantly Improve The Light Stability And Outdoor Weather Resistance Of The Film.
(S141,362, DPOP) With Diphenyl Phosphate And Tricresyl Phosphate In The Presence Of 10-15% Of Phthalate Plasticizer Such As DOP, Phosphoric Acid Diphenyl Isooctyl Ester (S141, 362, DPOP) Allows The Resulting Plastic To Have A Low Initial Viscosity And A Good Good False Plasticity And Storage Stability. Due To Its Good Pseudoplasticity And Film-Forming Properties It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To PMMA-Based Plastics And Nitrocellulose Coatings And Inks.
Mother granulation method: the flame retardant, carrier and stabilizer are mixed and granulated. The granule is the mother grain. When spinning, combine the mother grain with a certain proportion of the polypropylene slices, and then the spinning system has the flame retardant polypropylene fiber. This method is more common, reduces spinning temperature, improves the spinning ability of polypropylene, and has little influence on the strength, elongation and other quality of silk.
The copolymerization method is the method of adding flame retardants as one of the monomers to participate in the polymerization process of polymer polymerization. Polymer with this method is resistant to flame retardation. This method is mainly used for polyacrylonitrile and polyacrylonitrile (polyacrylonitrile) and polyamide.
Grafting modification method is used to make fiber and flame retardant monomer graft copolymerization with radiative heat, high energy electron beam or chemical initiator, so as to obtain effective and lasting flame retardant modification method. The flame retardancy of grafted flame retardant is related to the flame retardant elements in grafting monomers and the site of graft copolymerization.
The application of the flame retardant modification method of the core composite spinning is not very common, mainly because of the complex spinning equipment. In recent years, flame-retardant polyester fiber has been prepared by composite spinning, and the skin - core structure is adopted, which means that it is composed of copolymerization or additive type flame retardant polyester, which is composed of cortical composite. This can not only prevent premature halogen flame retardant decomposition hydrogen halide leave flame, flame retardant effect, and can prevent some phosphorus flame retardants is not the disadvantage of high temperature resistant, still can make the fiber to maintain the original appearance, whiteness and dyeing.
