Embodiment 1
[0021] The regenerated vegetable protein fiber such as corn protein fiber such as figure 1 Cut to 0.8mm as shown and refine again to obtain the regenerated vegetable protein fiber slurry, then mix it with the coniferous wood pulp fiber of 23 ° SR according to coniferous wood pulp fiber: regenerated vegetable protein fiber = 40:60 in the pulping tank uniform slurry, according to figure 2 As shown, use a paper machine to make a shape. After dehydration and primary drying, the functional additive polychitosan solution is coated on the paper surface according to 1% of the dry paper weight, and then dried for the second time to obtain a quantitative value of 35g / m2, special paper containing regenerated vegetable protein fibers with a thickness of 0.15mm, and then coiled, cut, and packaged to obtain the finished product.
Embodiment 2
[0023] Soy protein fiber such as figure 1 Shown cut to 0.5mm and then refining, to obtain regenerated vegetable protein fiber slurry, then with softwood pulp fiber, hardwood pulp fiber prepared respectively according to softwood pulp fiber: hardwood pulp fiber: regenerated vegetable protein fiber = 13:17:70 Mix the slurry evenly in the mixing tank, press figure 2 As shown, use a paper machine to make a shape. After dehydration and primary drying, the Zimbabwean tobacco leaf extract solution is coated on the paper surface by 5% of the dry paper weight, and then dried for the second time. Special paper with a thickness of 0.1mm containing regenerated vegetable protein fibers, then coiled, cut and packaged.
Embodiment 3
[0025] Papermaking is 60g / m2, thickness is the specialty paper that contains regenerated plant protein fiber of 0.32mm, and each material ratio is coniferous wood fiber: hardwood pulp fiber: regenerated plant protein fiber=30:10:60. Wherein the treatment of regenerated vegetable protein fiber pulp is as follows: figure 1 As shown, the regenerated plant protein fiber is first cut to 2.0mm ~ 5.0mm for pulping, and the regenerated plant protein fiber slurry and the coniferous wood pulp slurry of 38 ° SR are mixed evenly in the pulping tank, and press figure 2 The process shown is papermaking, dehydration, coiling after drying once, and then coating with the extract of tobacco produced in Honghe, Yunnan in off-line mode, and the coating application amount is 10% of the dry paper weight. After secondary drying, coiling, cutting and packaging are carried out.
