Based on art, non-woven moisture paper tissue material can be broken up by being prepared using nonwoven techniques such as wet-layings.The moisture paper tissue material, which removes, has one
As outside hygenic towelette characteristic, also with speed of production is high, yield is big, fibre web is quantitatively consistent, and quality is frivolous and degradable breaks up
Characteristic.But due to the limitation of wet laying process, the surface density that can break up moisture paper tissue material is only 50~60g/m2.
CN200910053210.6 discloses a kind of manufacture method of moisture paper tissue material, concretely comprises the following steps：First by viscose rayon
Mixed with being placed in after Time of Fluff Slurry wood pulp cellulose respectively shredding in smart pulverizer with weight ratio 25-45: 55-75, composite fibre is adopted
Spun lacing is reinforced after paper web is made with the dry method of paper-making, then dries to obtain moisture paper tissue material.The material properties test is as follows：Grammes per square metre：40g/
M2, thickness：0.42mm, tension failure strength：Longitudinal 65/5cm, horizontal 15N/5cm, vertical/horizontal ultimate strength ratio are：4.3, break
Split elongation：Longitudinal direction 12%, laterally：73%.As can be seen here, the Materials Fracture intensity is restricted, vertically and horizontally fracture strength ratio
It is larger.
