Question

Which of the following materials can make cloth fire-proof?
A) Copper oxide
B) Aluminium sulphate.
C) Nickel Chloride.
D) Magnesium sulphate.

Answer 1

Hint: We know Fire-retardant textures are materials that are more impervious to fire than others through substance treatment or fabricated flame resistant filaments. Fire-retardant materials ought not to be mistaken for fireproof materials. A fireproof material is one which is intended to oppose consuming and withstand heat. An illustration of a fireproof material is one which is utilized in fortification stuff worn by firemen to shield them from the blazes of a consuming structure.

Complete answer:
All textures will consume, however some are more flammable than others. Untreated characteristic strands like cotton, material and silk consume more promptly than fleece, which is harder to touch off and ignites with a low fire speed. The weight and weave of the texture will influence how effectively the material will touch off and consume.
Fire term and phosphorescence time diminished with expansion in alum focus while scorch arrangement and start time expanded with expansion in alum fixation. The work showed that aluminum sulfate is an extremely viable fire resistant polymeric material.

Hence, option B is correct.

Note:
Textures with a tight weave fleece, modacrylic, \[100\% \] polyester and those that are fire resistant are acceptable decisions. Substantial, tight weave textures will consume more gradually than free weave, light textures of a similar material. The surface of the texture likewise influences combustibility. Textures with long, free, cushy heap or "brushed" rest will touch off more promptly than textures with a hard, close surface, and now and again will bring about flares moving quickly over the texture surface.
