Embodiment 1
[0023] Step 1, sisal hemp is cut into the hemp fiber of 5cm;
[0024] Step 2, put the cut hemp fiber into a stainless steel container, mix it with sodium hydroxide solution, soak and stir for 1 hour to make the hemp fiber full, the sodium hydroxide solution is formed by mixing clear water with 99% pure sodium hydroxide, The mixing ratio is 8kg of sodium hydroxide per 100Kg of water;
[0025] Step 3, taking out the hemp fiber after the above-mentioned agitation treatment, washing it with clear water, removing the sodium hydroxide, and then putting it into hot water at 30° C. to remove the residual sodium hydroxide through a constant temperature bath;
[0026] Step 4, the hemp fiber obtained in step 3 is processed by oven drying;
[0027] Step 5, the hemp fiber after the drying of step 4 adopts every 100Kg clear water to be blended into 0.5% methyl methacrylate and 0.05% enammonium nitrate mixed solution to carry out soaking reaction;
[0028] Step 6, drying the hemp fiber aft...
