(2) carry out the stratum reticulare that is divided into slurry in pond with slurry with slurry with slurry with blanket layer, it is 50-100% short fiber that adjustment makes stratum reticulare with slurry, and 0-50% is long fine, and blanket layer is with slurry is short fiber 0-50%, the fine 50-100% of length, stratum reticulare amount of slurry: blanket layer slurry weight is 0.6-1.2;
(3) with slurry complete after pull an oar, blanket layer making beating after beating degree be 25-45 ° of SR, the concentration of making beating is 4%-5%, and temperature is 40 DEG C, and PH is 6-8; After stratum reticulare making beating, beating degree is 25-35 ° of SR, and the concentration of making beating is 4%-5%, and temperature is 40 DEG C, and PH is 6-8; Then the slurry that stratum reticulare is with slurry enters in stratum reticulare machine chest, and blanket layer slurry with slurry enters in blanket layer machine chest after making beating;
(4) by fan pump, the laggard row filter of slurry is rushed respectively to the slurry in slurry in stratum reticulare machine chest and blanket layer machine chest;
(5) slurry enters crescent forming paper machine and manufactures paper with pulp, and whitewashing online concentration is 0.1%-0.3%, and pressure roller adopt shoe press roll, slurry enters pressure roller moisture less than 60%, go out pressure roller moisture less than 45%, then enter dryer surface and dry, ensure into guard shield moisture less than 30%;
(6) use ceramic blade to carry out making into wrinkling, scraper cornerite 60-110 °, and continue to use cleaning doctor and spray limit to modify drying cylinder coating;
(7) use creping doctor to carry out wrinkling, wrinkling mass dryness fraction is 2 ~ 8%, and wrinkling pressure is 2-4bar, and creping doctor angle is 0-20 °;
(8) just winding up roller carries out just volume, controls just to roll up speed, makes crepe ratio be 10-25%.
2. a kind of pliable and tough tissue paper according to claim 1, is characterized in that: the place in loose stock tank, machine chest, fan pump or drying cylinder coating or many places are added with softener, total consumption of described softener is 0.1-5Kg/t.
3. a kind of pliable and tough tissue paper according to claim 2, is characterized in that: described softener is evenly added on fan pump and/or dryer surface place.
4. a kind of pliable and tough tissue paper according to Claims 2 or 3, is characterized in that: described softener is: quaternary, fatty acid ester type, paraffin wax type, polyethylene or organic siliconresin type softener.
5. a kind of pliable and tough tissue paper according to claim 1, is characterized in that: be added with dry strength agent in described machine chest, and the consumption of described dry strength agent is 0-13Kg/t.
6. a kind of pliable and tough tissue paper according to claim 5, is characterized in that: described dry strength agent is: starch, cationic starch, anionic starch, polyacrylamide, glyoxal polyacrylamide or polyvinyl alcohol.
7. a kind of pliable and tough tissue paper according to claim 1, is characterized in that: the grout outlet place of described machine chest is added with wet strength agent, the consumption of described wet strength agent is 0.1-12Kg/t.
8. a kind of pliable and tough tissue paper according to claim 7, is characterized in that: described wet strength agent is: urea-formaldehyde resins, melamine formaldehyde resin or Polyamide-Polyamsne-Epichlorohydrin resin.
