preparation example Construction

[0031] The present invention also protects the preparation process of a kind of nylon flame-retardant fiber is:

[0032] 1) Grinding of flame retardants: use zirconium ball grinding or jet grinding to obtain at least submicron flame retardants. Level; the flame retardant here can be a single flame retardant or a mixture of various substances. When mixing, the decomposition temperature of each component in the mixture is required to be greater than 300°C. The mixed substances are ground separately to meet the particle size. After the required particle size is obtained, it is fully mixed to form a spinnable flame retardant;

[0033]2) Preparation of nylon flame retardant slices: fully mix the flame retardant that can reach the level of spinning and mix it with nylon 66 salt (hexamethylenediamine adipate) or nylon 6 salt (caprolactam salt) according to the proportion, add a certain amount The water is made into flame-retardant brine, stirred and mixed evenly, and pumped into the...

Embodiment 1

[0052] Embodiment 1: Armed police use special warfare camouflage camouflage webbing

[0053] In this embodiment, the armed police camouflage webbing for special warfare is a high-strength nylon 66 flame-retardant camouflage webbing, and its production process includes the following steps:

[0054] 1. Flame retardant grinding: use zirconium balls to grind the micron-sized flame retardants to obtain at least submicron-sized flame retardants, which can reach the spinnable level; the specific method is to use zirconium balls to grind the flame retardant particles The diameter drops to about 450nm, reaching the spinnable level. The particle size of the selected zirconia balls is 0.23mm.

[0055] 2. Preparation of nylon flame retardant slices: Mix the flame retardant that can reach the level of spinning and nylon 6 salt according to the ratio and add water to make a salt solution. Stir and mix evenly and input it into the reactor through a pump, continue to stir and raise the tempe...

Embodiment 2

[0073] Example 2: 07 woodland camouflage camouflage webbing

[0074] Production step is the same as embodiment 1, and printing formula is different, and process is coordinated as follows:

[0075] Black: black LD: 10.344; 4732 blue 2.25g / 500g; 4384 sauce red 4.4;

[0076] Brown: black LD: 12.422; 4380 yellow 30.656; 4384 sauce red 4.459;

[0078] Green: black LD 0.504; 4380 yellow 0.952, 4384 sauce red 0.115;

[0079] Others: urea 5%, citric acid 2%, water 29.8%, white pulp 68%.

[0080] In summary, the embodiments of the present invention have the following beneficial effects: in the embodiment 1 and embodiment 2 of the present invention, the nylon 66 camouflage camouflage webbing made is more traditional padding process (this application is not a padding, but adopts flame-retardant fiber weaving The camouflage webbing itself has flame retardant performance, no need to pad again for flame retardant, jus...

Abstract

The invention relates to a nylon flame retardant fiber and its products. The flame retardant fiber contains a spinnable submicron or nanometer flame retardant with a decomposition temperature greater than 300°C. The preparation process of the flame retardant fiber is as follows: grinding the flame retardant of micron level to obtain at least submicron level flame retardant to reach the spinnable level; fully mixing the spinnable level of flame retardant according to the proportion and Mix nylon 66 salt or nylon 6 salt, add water to make flame-retardant brine, stir and mix evenly, and input it into the reactor through a pump. Extrude, melt and extrude filaments, pelletize under water, and prepare nylon flame-retardant chips; mix nylon flame-retardant chips and nylon 66 chips at a weight ratio of 1:12-15, and melt-spin to prepare nylon flame-retardant fibers. The flame-retardant fiber has high strength and good flame retardancy. The webbing made of this fiber has a permanent flame-retardant effect, and has camouflage and water-repellent properties.

Description

1. Technical field [0001] The invention relates to a nylon flame-retardant fiber and its products, in particular to the production of a nylon camouflage webbing, in particular to a high-strength nylon 66 flame-retardant fiber and a camouflage webbing. 2. Background technology [0002] Nylon has the characteristics of high strength, wear resistance, high elasticity, high temperature resistance, and good energy absorption. In view of the outstanding performance of nylon, the moll camouflage webbing used in traditional domestic military carrying equipment and bulletproof vests is made of polyester, and there is no camouflage. Or camouflage performance, mainly in military green. With the accelerated pace of troop replacement, higher requirements are put forward for the performance of equipment materials. Nylon materials are required, and flame retardant, camouflage, camouflage and water repellency requirements are also required. The flame retardant of camouflage webbing mainly a...
