Step one: mixing; Utilize opener and mixture griping cotton machine by the glass fibre under normality and aramid fiber or PSA fiber garnetting, play pine and removal of impurities, and by glass fibre together with aramid fiber or PSA fiber Homogeneous phase mixing, form composite fibre;
Step 2: shredding; Used by the composite fibre mixed opener by further for fiber garnetting, play loose and removal of impurities, make mixed fiber become cotton-shaped, fluffy glass fibre and aramid fiber or PSA fiber mixture;
Step 3: smart shredding; Again by the mixture garnetting mixed, beat pine and removal of impurities, by mixture shredding to not being wound around between glass fibre and the monfil of aramid fiber or PSA fiber and having gap;
Step 4: feeding; The glass fibre of smart shredding and aramid fiber or PSA fiber are fed in cotton feeder, utilize Electronic Control weighing instruments to control the weight of feeding glass fibre and aramid fiber or PSA fiber, and combed into carding process;
Step 5: combing; Glass fibre in step 4 and aramid fiber or PSA fiber are carded to the staggered net of certain thickness radial broadwise by carding machine, realize being connected between net and net, carry out orderly arrangement between different classes of fiber;
Step 6: lapping; Flush system lapping machine is utilized net good for combing evenly, reciprocally to be tiled 8-12 layers in fiberglass-based cloth two side;
Step 7: pre-needling; Net and fiberglass-based cloth are made to be cross-linked between net and fiberglass-based cloth after acupuncture, forms the mixture of three-dimensional structure;
Step 8: main acupuncture; Utilize 5-6 platform high frequency needle punching machine, take dystopy to the mode of thorn, use mold pressing pricker three pricker, by reciprocal for fiber acupuncture, occlusion, formed between fiber from obvolvent, to reach the three-dimensional structure thorn felt blank mixture of high strength, low elongation;
Step 9: sizing; The three-dimensional structure thorn felt blank mixture that step 8 is completed, mechanical type imports the high temperature oven of 220-260 DEG C, and 180-190s is dried in training, then through naturally cooling, forms the setting three-dimensional structure thorn felt of dimensionally stable;
Step 10: calendering of singing; The fiber filoplume wadding on surface burnt by three-dimensional structure thorn felt step 9 completed by naked light, allow three-dimensional structure sting felt and form smooth surface;
Step 11: post processing; By the three-dimensional structure thorn felt through high-temperature shaping, infiltrate in the mixing material of polytetrafluoroethyldispersion dispersion, adhesive, industrial alcohol, through dipping, coating, writing that surpasses all the others, import the high temperature oven of 220-260 DEG C again, 240-290s is dried in training, finally obtains glass fibre and aramid fiber or PSA fiber compound spiked felt.
3. the manufacture method of glass fibre according to claim 2 and aramid fiber or PSA fiber compound spiked felt, is characterized in that: the Main Ingredients and Appearance of the adhesive in step 11 is acrylic resin.
4. the manufacture method of glass fibre according to claim 2 and aramid fiber or PSA fiber compound spiked felt, is characterized in that: in step 11, mixing material polytetrafluoroethyldispersion dispersion, adhesive, industrial alcohol are (60 ~ 70) according to mass ratio: (10 ~ 20): (20 ~ 30).
