3) the above-mentioned polyester staple fiber having taken is carried out to shredding processing by opener;
4) by 2) with 3) in chopped carbon fiber with polyester staple fiber at least mixing in twice cotton blender machine, to ensure that chopped carbon fiber fully mixes with polyester staple fiber;
5) by 4) in well-mixed fibre blend enter and in first carding machine, carry out combing processing for the first time;
6) blended fiber after treatment combing for the first time Netcom is crossed to lapping machine carries out lapping and changed course is processed;
7) again by 6) in blended fiber net carry out combing processing through at least one carding machine, it is mixed completely evenly;
8) finally use the high temperature pressure roller of 230-240 degree Celsius to 7) in blended fiber net carry out hot pressing and squeeze and process, synthetic polyster fibre electric heating non-woven paper.
The length of described chopped carbon fiber is 6-30 millimeter.
The length of described polyester staple fiber is 30-60 millimeter.
The thickness of described polyester staple fiber is that 1.5-2 is smooth.
In described carding machine, the number of doffer's roller is no less than 2.
Adopt carbon fiber electrothermal plate to carry out drying and processing to chopped carbon fiber.
Compared with prior art, the beneficial effect producing is a kind of polyster fibre electric heating non-woven paper manufacture method of the present invention:
First the present invention first carries out drying and processing to chopped carbon fiber, polyester staple fiber is carried out to shredding processing, then chopped carbon fiber and polyester staple fiber are pressed to (6%-18%): percentage by weight (82%-94%) fully mixes in cotton blender machine, carrying out multiple tracks combing by carding machine more completely evenly mixes it, last in the situation that not adding any auxiliary agent and additive, through the synthetic even thickness of high temperature squeezing roll-in, carbon fiber is evenly distributed, intensity is high, WATER RESISTANCE is strong, anti acid alkali performance, there is the electric heating non-woven paper of certain telescopicing performance, reliable in quality, long service life.
(4) detailed description of the invention
Below a kind of polyster fibre electric heating non-woven paper manufacture method of the present invention is described in detail below.
A kind of polyster fibre electric heating non-woven paper manufacture method of the present invention, the raw material of the method comprises chopped carbon fiber and polyester staple fiber, the method is carried out according to following steps:
1) first taking length is 100 parts of the chopped carbon fibers of 20 millimeters, and length is that 45 millimeters, thickness are 900 parts of 1.7 smooth polyester staple fibers.
2) then with carbon fiber electrothermal plate, above-mentioned 100 parts of chopped carbon fiber carbon fibers are carried out to drying and processing, and be evenly sprinkling upon afterwards on the convoying curtain of first cotton blender machine entrance in oven dry.
3) by opener, above-mentioned 900 parts of polyester staple fibers are carried out to shredding processing, so that can better mix in next step cotton blender machine.Wherein, the opener that in this process, polyester staple fiber is carried out to shredding processing is prior art.
