C, the 3rd road fibrillation, fine fibre made by crude fibre, and make the fibre length of kraft fibers be 3-7mm, fibre diameter is 0.3mm.
Above-mentioned three road fibrillation step detailed processes are as follows:
1, first fibrillation, cuts into most of fritter square for the 1cm × 1cm of regular size by irregular bulk ox-hide.
Choose clean pure ox-hide leftover pieces through preliminary treatment, make its moisture content reach 80%, above-mentioned preprocessing process is the drying and processing of spraying process or less than 50 DEG C, and the selection of preprocess method is determined according to the moisture content of pure ox-hide raw material.
Enter fibre separating machine through pretreated pure ox-hide leftover pieces and carry out first fibrillation, the blade of High Rotation Speed makes the material in sieve plate be divided into fritter ox-hide, sieve plate is the meshed stainless steel cylinder of band, the screen deck net hole dimension of first fibrillation is 10mm × 10mm, then selection by winnowing deslagging, discharging size inhomogenous particle, is the square fritter ox-hide of 1cm × 1cm to obtain the major part of size uniformity after guaranteeing first fibrillation; First fibrillation is less compared to rear twice fibrillation step bed drain purge.
2, second fibrillation, makes the fritter ox-hide of regular size change the crude fibre that length is 0.8cm-1cm into;
Square fritter ox-hide is through atomization process, moisture content reaches 80%, enter fibre separating machine and carry out second fibrillation, the screen deck net hole dimension of second fibrillation is 10mm × 7mm, selection by winnowing deslagging, discharge size inhomogenous particle, to obtain the ox-hide crude fibre of length in 0.8-1cm scope of size uniformity after guaranteeing second fibrillation.
3, the 3rd road fibrillation, fine fibre made by crude fibre, makes the fibre length of kraft fibers control within the scope of 3-7mm, and fineness degree is about 0.3mm.
Ox-hide crude fibre is through atomization process, moisture content reaches 80%, enter fibre separating machine and carry out the 3rd road fibrillation, the screen deck net hole dimension of the 3rd road fibrillation is 15mm × 1.5mm, selection by winnowing deslagging, discharge the inhomogenous particle of size, obtaining fibre length is 3-7mm, and fineness degree is the kraft fibers of about 0.3mm.
The kraft fibers that this method obtains can meet the requirement that papermaking becomes net and water thorn compound, and as fiber is oversize, papermaking wet-laying just can not ensure with regard to the uniformity, and fiber is too short, stings with nonwoven water distribution the requirement that combined strength bination just can not reach leather.Further, according to the utility model people repeatedly experience that obtains of compound, fiber is too thin, and fibrous elasticity just can not ensure, the too thick and non-woven fabric compounded intensity of fiber can not ensure.
