Problems solved by technology

[0004] Thermoplastic polymers such as polyester, nylon, polyethylene and other plastics, because they are composed of carbon, hydrogen, and oxygen, polymers are prone to generate active free radicals at high temperatures, thereby accelerating the degradation of polymers, thereby decomposing flammable gas components, Accelerate its degradation, so for the flame retardant modification of thermoplastic polymer materials, in order to achieve the optimal effect, the main way is to improve its ability to capture active free radicals; for warp-knitted lace fabrics, first of all, it can choose The raw material of the fabric is an intrinsic flame retardant polymer, and its flame retardant modification can also be achieved through finishing methods; however, the current finishing flame retardant fabrics also generally exist, with poor flame retardancy, low flame Due to the disadvantage of poor washability, it is necessary to use intrinsically flame-retardant polymer materials to realize the development of flame-retardant fabrics, which not only avoids the difficulty of fabric recycling and separation, but also increases the added value of products

Embodiment 1

[0076] A flame-retardant warp-knitted lace fabric has a flame-retardant limiting oxygen index of 30%, a vertical flammability of UL-94 of V0 level, and a carbon residue of 25% after being calcined at 500°C for 30 minutes.

[0077] Please see attached figure 1 , a production method of flame-retardant warp-knitted lace fabric, which specifically comprises the following steps:

[0078] 1. Preparation of flame retardant polyester masterbatch

[0079] The first step of preparation of the flame retardant modifier is to use trimesic acid and methanol as raw materials, use concentrated sulfuric acid as a catalyst, and carry out esterification reaction at a pressure of 0.25-0.35MPa and a reaction temperature of 105-120°C. After the esterification reaction for 2.5-3.5 hours, the esterified product was obtained. After the esterification reaction, the unreacted methanol was distilled off from the esterified product at 100°C under reduced pressure, and then tribromoneopentyl alcohol was a...

Abstract

The invention relates to anti-inflaming tricot lace fabric and a production method thereof. The anti-inflaming tricot lace fabric is characterized in that a flame resistance limit oxygen index is 30 to 34 percent, the vertical combustibility UL-94 is V0 class, and the residual carbon content by calcining the anti-inflaming tricot lace fabric under 500 DEG C for 30 minutes is 25 percent. The anti-inflaming tricot lace fabric comprises a flame retardant structure with a free radical capturing function, the carbon forming performance of the anti-inflaming tricot lace fabric is further increased through a benzene ring structure in flame retardant molecules, the flame retardant effect is increased, the effects of flame retarding and carbon forming are increased by utilizing the synergistic effect of bromine-containing functional groups and the benzene ring structure, and the melt dripping resistance is further enhanced; meanwhile, the molecules contain methoxyl functional groups capable of carrying out transesterification, methyl alcohol in a transesterification process is in a micromolecule form, the boiling point of the methyl alcohol is lower than that of water molecules, the volatility is good, and saturated vapor pressure is far below that of water vapor molecules, so that the methyl alcohol formed through transesterification is beneficial for removing of micromolecules in a polycondensation process, particularly, chain segments in a later period are lengthened, the removing of the micromolecules is difficult during a viscosity increment process, and a chain segment lengthening process is difficult to achieve; the anti-inflaming tricot lace fabric is applied to the fields of textile, decorative fabric and the like, and the application prospect is wide.
