Phosphatides without halogen flame retardants
In this paper, the flame retardant finishing of polyamide fabric is carried out with phosphate-free flame retardant. The effects of various factors on the flame retardant effect were discussed, and the optimization process of the flame retardant finishing of the non-halogen flame retardant was obtained, which was 200 & ZL, 15 g/L, and the soaking temperature eot x3 h. The formaldehyde content of the finished fabric is 0.43 mg/kg, and the flame retardant performance of 15 times after washing has reached the American aviation fire protection standard, which has good flame retardancy and durability.
The melting and drop of polyamide in the burning of polyamide is easy to cause the fire to spread, thus limiting its application. Ordinary flame retardant polyamide fabric adopt halogen flame retardant, although has flame retardant effect, but used in plane, train, car and other traffic tools, easy to release toxic gas, reduce visibility, bring safe hidden trouble. The activity of polyamide is poorer, result in flame retardant finishing liquid cannot penetrate into the fibers, which reduces the flame retardant effect, wash degree difference using phosphate ester halogen free flame retardants for flame retardant nylon fabric finishing, excellent durability.
Phosphate ester of halogen free flame retardant flame retardant finishing process test material: emulsifier LF100, piece of alkali, phosphate ester flame retardant agent, penetrating agent (isopropyl alcohol), polyamide 66 fabric, fabric warp and weft density, respectively 75160 root / 10 cm, weight 0.318 kg/m2.
Phosphate ester of halogen free flame retardant flame retardant finishing process test equipment: electronic scales, digital display HH - S constant temperature water-bath water, direct combustion test apparatus, Siemens fully automatic washing machine, curing oven, GDW/JB - 0100 type low temperature alternating test chamber, the GDYQ - 201 type sy textiles formaldehyde tester.
Phosphate ester of halogen free flame retardant flame retardant finishing technological process: the preparation of flame retardant liquid - dipping bath ratio 1: 丨 (0) - (8 min) ^ drying dehydration (70 t x min)? Performance testing.
The flame retardant performance test adopts the vertical method, which is based on the standard GB/T 8745 "determination of the burning time on the surface of textile combustion properties" (ISO 10047-1993, IDT).
The test of washable performance refers to GB/T 8629-2001 "home washing and drying procedures for textile tests" (ISO 6330:2000).
The phosphoric acid produced by the combustion of phosphate flame retardant can form stable polymerization, covering the surface of the material, isolating oxygen and combustible materials. In addition, the combustion process can promote the conversion of organic matter into carbon (element carbon), reducing the formation of flammable carbonic gas. Carbon also blocks oxygen and heat from burning objects to keep things from burning.

In the flame retardant finishing process, the flame retardant is the heavy factor to determine the flame retardant effect. The larger the flame retardant dosage, the better the flame retardant effect. The permeating agent can promote the dispersing of the finishing agent evenly to the inside of the fiber and increase the fixation rate of the flame retardant. In order to make the flame retardant fast and the fibrous macromolecule reaction, the leaching temperature will also play a certain role in the reaction.
The high temperature and long time can accelerate the dispersing of the finishing agent to the inner fiber. Of course, the time of immersion is not longer, the expansion of the fiber capillary and the crosslinking reaction are limited, and energy consumption and actual production efficiency should also be considered. Discussion in the finishing process so flame retardant with child, penetrating agent, dipping temperature and time on fabric flame retardant effect is necessary, and optimize process when the main factors must be considered.
The effect of the dosage of combustible agent on the flame retardant property: process parameters: 15 g/L of osmotic isopropyl alcohol, bath ratio 1:10, soaking condition 60 g x2 h, and 1 g/L of flame retardant. As the dosage of flame retardants increased, the phosphorus content in the fabric increased, and the flame retardant performance increased, but the flame retardant effect decreased after the increase of 250 g/L.
This is because some of the flame retardants do not combine well into the fabric, resulting in the decrease of the content of the actual flame retardant; In addition, the increase of the content of flame retardants although solid phase and gas phase flame retardant effect, but because of the heat release by the decomposition of flame retardants will be feedback to the fabric, adding fiber into solution, which reduces the flame retardant performance.
