Embodiment Construction

[0010] Take 70 parts of dried PP chips (weight, the same below); 10 parts each of calcium silicate, magnesium silicate, and aluminum silicate nanoparticles. granules to produce a mixture for spinning; after the obtained mixture is fully dried, the polypropylene UDY yarn is spun by melt spinning, and the UDY yarn is stretched on a VC403 drafting machine to obtain a flame-retardant polypropylene DT Silk.

[0011] Combustion test was carried out on this embodiment: the fiber was baked at a high temperature of 1200° C. with a household gas stove, and an obvious yellow flame could be seen, but there was no dense smoke. After the fiber is removed, it will automatically go out after about 7 seconds, and immediately use a thermometer to test its surface temperature, which shows 57°C. Through this test, it can be verified that the flame retardant fiber described in this example has obvious high temperature and flame retardant effect.

Abstract

The present invention provides a novel halogen-free high temperature preventing flame-retardant fiber. The present invention is realized in the following way: a certain proportion of silicate nanometer particles are added into spinning melt to be mix fully, and the production is executed according to common chip spinning or melt spinning production flow to prepare the present invention; or the silicate nanometer particles and common high polymer chips are mixed and then mutually melted into flame-retardant master batch under certain temperature, and the present invention is prepared by executing twin-screw spinning to the master batch and high polymer having the same composition with master batch carrier. As the present invention adopts halogen-free compounds as flame-retardant composition, no poisonous gas can be produced during combustion; meanwhile, due to the special chemical composition of silicate, the present invention can combine a large amount of combined water, and leads the burning rate of the fiber to be slower during the process of releasing the combined water, so as to play a role in preventing high temperature. The technique is also characterized in green environmental protection.

Description

technical field [0001] The invention relates to a functional synthetic fiber and belongs to the technical field of textiles. Background technique [0002] Ordinary flame-retardant fibers are mixed with ordinary synthetic fibers by adding a compound that generates non-combustible gas at high temperature during the production process, so as to prevent the fibers from continuing to burn. However, these compounds generally have halogen atoms or molecules. Although the gases emitted by them can block the air and prevent combustion, they themselves also cause great harm to people's health. This limits the scope of use of flame retardant fibers. Contents of the invention [0003] Aiming at the above-mentioned defects of common flame-retardant fibers, the present invention provides a new halogen-free high-temperature resistant flame-retardant fiber. [0004] The present invention is achieved in this way: in the process of melt spinning, add 2 to 5% silicate nanoparticles in the ...
