Automobile trim material combined with non-woven fabric and woven fabric

[0025] Step 1. Cut the natural fibers into short fibers of 50mm, put them in a stainless steel container and mix them with sodium bicarbonate solution and stir for 60 minutes. Mix 10% by weight with water to form a solution;

[0026] Step 2. Wash the hemp fiber with clean water to remove the sodium bicarbonate solution in the natural fiber, then put it in a constant temperature bath in warm water at 20°C for 60 minutes, remove the residual sodium bicarbonate in the fiber solution, and then vacuum dry it;

[0027] Step 3, adding 0.5% styrene monomer and 0.8% cerium ammonium nitrate by weight to the dried natural fibers, performing a chemical reaction, washing with clear water, and then drying;

[0028] Step 4, put the dried natural fibers on the wool machine equipment and open and mix with polypropylene fibers to obtain mixed fibers. The proportion of natural fibers and polypropylene fibers is distributed by weight: 50% of natural fibers, 50% of polypropylene fibers 30%;

[0038] Step 1. Cut the natural fibers into short fibers of 60 mm, put them in a stainless steel container and mix them with sodium bicarbonate solution and stir for 70 minutes. Mix with clear water by 15% by weight to form a solution;

[0039] Step 2. Wash the hemp fiber with clean water to remove the sodium bicarbonate solution in the natural fiber, then put it in a constant temperature bath in warm water at 25°C for 70 minutes, remove the residual sodium bicarbonate in the fiber solution, and then vacuum dry it;

[0040] Step 3, adding 1% by weight of styrene monomer and 0.1% cerium ammonium nitrate to the dried natural fibers, performing a chemical reaction, washing with clear water, and then drying;

[0041] Step 4. Put the dried natural fibers on the wool machine equipment and open and mix with polypropylene fibers to obtain mixed fibers. The proportioning ratio of natural fibers and polypropylene fibers is as follows: natural fibers 60%, polypropylene fibers 40%;

[0051] Step 1. Cut the natural fibers into short fibers of 70 mm, put them in a stainless steel container and mix them with sodium bicarbonate solution and stir for 80 minutes. Mix with clear water by 20% by weight to form a solution;

[0052] Step 2. Wash the hemp fiber with clean water to remove the sodium bicarbonate solution in the natural fiber, then put it in a constant temperature bath in warm water at 30°C for 80 minutes, remove the residual sodium bicarbonate in the fiber solution, and then vacuum dry it;

[0053] Step 3, adding 1.2% styrene monomer and 0.12% cerium ammonium nitrate by weight to the dried natural fibers, performing a chemical reaction, washing with clear water, and then drying;

[0054] Step 4, put the dried natural fiber on the wool machine equipment and open and mix with polypropylene fiber to obtain mixed fiber. The proportion of natural fiber and polypropylene fiber is divided by weight: natural fiber 70%, polypropylene fiber 50%;
