Description
Technical field
Not only may be implemented 100% the present invention relates to one kind can break up degradable, but also reinforced with a kind of good thermosol of intensity
Degradable non-woven material and production method can be broken up, non-woven material manufacturing field is belonged to.
Background technique
Type non-woven material is broken up in this dragon Ahlstrom of Austria manufacture of Finland, constitutes upper (1) PP/ in the formula of non-woven material
The mixing of PE/:PP or PE；Structure: PP is coated on the core material fiber type of PE outer layer, and PP fusing point is high, and PE fusing point is low；Its deficiency
Place: water imbibition is poor, and dispersibility reduces obviously, and cannot achieve degradable.
Summary of the invention
Purpose of design: avoiding the shortcoming in background technique, designs a kind of be both able to satisfy and regenerates non-woven material entanglement
The requirement of intensity, and can quickly be broken up under the action of impact of water, a kind of broken off by water flush degradable of 100% degradable regeneration nonwoven
Material and production method.
Design scheme: in order to realize above-mentioned purpose of design.1, weight percent be PVA hot melt fiber be 1%---5% it
Between and including end value, regenerated celulose fibre be between 1%---50% and including end value, wood pulp be between 98%---45% and including
The design of end value is one of technical characteristic of the invention.The purpose of this design is: since regenerated celulose fibre is with good
Good hygroscopicity, under the conditions of general atmosphere, regain significantly expands after 10-13%, moisture absorption, and diameter increases up to 50%, knits
Object is lauched rear feel and hardens, and shrinking percentage is big, thus the selection how much of its ratio is directly related to constituted regeneration non-woven material
Flexibility and dispersibility.The ratio that regenerated celulose fibre is chosen is big, and entanglement is good, intensity is high, but is not only not easy to rush after meeting water
It dissipates, is agglomerated instead by its big influenced of shrinking percentage, cause to be difficult to break up；Though conversely, meeting, broken off by water flush is good, and entanglement is poor,
Intensity is low, is not able to satisfy requirement.Thus the application be by weight percentage PVA hot melt fiber be between 1%---5% and
It is between 1%---50% and including end value, wood pulp including end value, regenerated celulose fibre is between 98%---45% and including end value
When being made that thermosol is reinforced to break up non-woven material, since PVA fiber (vinal) is a kind of water-soluble fiber, when
Fiber is by water complete wetting, and after water temperature reaches its dissolved click, fiber will dissolve, after moisture evaporation after, PVA will again at
Film, thus make to fill up in fiber gap or be covered on the PVA fibres bonds in contact of other fiber surfaces together,
The use intensity requirement of regeneration non-woven material can not only be met, and solve binder fibre to influence product biological degradability
Problem realizes the purpose of water punching dispersion degradable.2, regenerated celulose fibre face is technology of the invention by the design of plucking
The two of feature.The purpose of this design is: regenerated celulose fibre is made into fiber surface plucking by throwing hair machine, it both can be with
The surface area of fiber is greatly improved, and its obvolvent, entanglement power can be strengthened in the manufacturing process of regeneration non-woven material, from
And solution amount entanglement power and the high purpose of entanglement strength less, while it again can be swollen by wood pulp cellulose moment under the action of Shui Chong
Swollen institute's disintegration, to achieve the purpose that water rushes rapid dispersion.
Technical solution 1: a kind of thermosol is reinforced to break up degradable non-woven material, weight percent: PVA hot melt fiber
It is between 1%---50% and including end value, wood pulp 98%--- between 1%---5% and including end value, regenerated celulose fibre
Between 45% and including end value.
Technical solution 2: a kind of thermosol is reinforced to break up degradable non-woven material, including spun lacing nonwoven production work
Skill, by PVA hot melt fiber be between 1%---5% and including end value, regenerated celulose fibre be between 1%---50% and including
Between 98%---45% and when the spun lacing non-woven material drying including end value production, hygrometric state spun lacing non-woven material exists for end value, wood pulp
It is heated in baking oven, when hygrometric state non-woven material reaches 65 DEG C -120 DEG C, the PVA fiber in non-woven material takes place water-soluble
Solution, fills up in other fiber gaps or is coated on other fiber surfaces, when product is further oven-dried, PVA fiber is not
It can lose, and be mixed together with other fibers, the type of being strengthened can break up degradable non-woven material.
Compared with the background technology, the present invention, first is that being not only able to satisfy the requirement of regeneration non-woven material entanglement intensity, but also can be
It is quickly broken up under the action of impact of water；Second is that after thermosol PVA is added, it, can be with while improving product strength using binder fibre
Realize 100% biodegrade；Third is that this surface of regenerated celulose fibre by the design of plucking, both increases regeneration non-woven material table
The faying face in face, solution amount entanglement power and the high purpose of entanglement strength less, and can under the action of Shui Chong rapid dispersion.
