Description
Technical field
The present invention relates to a kind of degradation rate for breaking up material more than 95% and with high intensity one kind hot melt it is reinforced
Non-woven material and preparation method can be broken up, belongs to non-woven material manufacturing field.
Background technology
Type non-woven material is broken up in this imperial Ahlstrom manufacture difficult to understand of Finland, is formed in the formula of non-woven material（1）PP/
PE/:PP or PE mixing；Structure：PP is coated on the core fiber type of PE outer layers, and PP fusing points are high, and PE fusing points are low；Its deficiency
Place：Water imbibition is poor.（2）PET/COPET：The core type that COPET is coated on PET outer layers using modified polyester fiber and COPET is fine
Dimension, advantage water imbibition ratio（1）By force, but because PET fusing points are high, COPET fusing points are low, and both can not be adapted to, in hygrometric state nonwoven material
When material carries out drying tunnel drying, when PET reaches fusing point, aging of superfusing then occurs for COPET, causes non-woven material intensity decreases, soft
Poor toughness.
The content of the invention
Purpose of design：The weak point in background technology is avoided, design one kind can meet to regenerate non-woven material entanglement
The requirement of intensity, and can realizes hot melt adhesion between few fibers and fiber, while and can is quickly rushed in the presence of impact of water
A kind of scattered broken off by water flush degradation-type regeneration non-woven material and preparation method.
Design：In order to realize above-mentioned purpose of design.1st, percentage by weight：ES fibers or PET/COPET blended fibers
Proportioning between 1%---5% and including end value, regenerated celulose fibre proportioning between 1%---50% and including end value, wood
Starch between 98%---45% and the design including end value, be one of technical characteristic of the present invention.The purpose so designed is：
Because regenerated celulose fibre has good hygroscopicity, under the conditions of general atmosphere, regain is notable after 10-13%, moisture absorption
Expand, diameter increase reachable 50%, feel is hardened after water under fabric, and shrinkage factor is big, thus the selection direct relation that its ratio is how many
To the regeneration non-woven material pliability and dispersiveness formed.The ratio that regenerated celulose fibre is chosen is big, and entanglement is good, intensity
Height, but be not only not easy to break up after meeting water, condensed on the contrary by its big influenceed of shrinkage factor, cause to be difficult to break up；Though conversely, meet water
Breaking up property is good, but entanglement is poor, low intensity, it is impossible to meets requirement.Thus the application is by weight percentage：ES fibers or
The proportioning of PET/COPET blended fibers between 1%---5% and including end value, regenerated celulose fibre proportioning in 1%---50%
Between and including end value, wood pulp between 98%---45% and including end value be made hot melt it is reinforced break up non-woven material when, melt
The relatively low thermoplastic fibre of point, such as the PE layers of ES fibers, the COPET layer of PET/COPET fibers etc., after heating melts, main body
Mutually bonded between fiber or between main fibre and other fibers, can not only meet that the use intensity for regenerating non-woven material will
Ask, and the spun lacing pressure needed for tangling can be reduced, so as to keep the low entangled state between most of fiber, realize water punching
Scattered purpose.2nd, regenerated celulose fibre face is the two of the technical characteristic of the present invention by the design of plucking.The mesh so designed
Be：By regenerated celulose fibre by throwing hair machine, make fiber surface plucking, the surface area of fiber can both be greatly improved,
Its obvolvent, entanglement power it can be strengthened in the manufacturing process of regeneration non-woven material again, so as to which solution amount entanglement power and twines less
The high purpose of knotting strength, at the same its and can it is enough in the presence of Shui Chong by wood pulp cellulose instantaneous expansion institute disintegration, so as to reach water
Rush the purpose of rapid dispersion.
Technical scheme 1：One kind hot melt is reinforced to break up non-woven material, percentage by weight：ES fibers or PET/COPET
The proportioning of blended fiber is between 1%---5% and the proportioning including end value, regenerated celulose fibre between 1%---50% and is wrapped
End value, wood pulp are included between 98%---45% and including end value.
Technical scheme 2：One kind hot melt is reinforced to break up nonwoven production technique, is total to by ES fibers or PET/COPET
The proportioning of combined filament between 1%---5% and including end value, regenerated celulose fibre proportioning between 1%---50% and including
When the spun lacing non-woven material that end value, wood pulp make between 98%---45% and including end value is dried, ES fibers are at 150 DEG C -170
Puddle at DEG C, fiber is adhered to one another with fiber, forms the non-woven fabrics formed body without adhesive；Or PET/COPET blendings
Fiber makes main fibre mutually bonding or main fibre mutually be bonded with other fibers, is formed and do not have to bond after heating melts
The non-woven fabrics formed body of agent.
The present invention is compared with background technology, first, one is that after hot melt PE or PET/COPET is added, can not only meet again
The use intensity requirement of raw non-woven material, and the spun lacing pressure needed for tangling can be reduced, make the holding between most of fiber
Low entangled state, the degradability of product is set to have reached more than 95%；Second, this surface of regenerated celulose fibre is by the design of plucking,
Both the faying face on regeneration non-woven material surface is increased, entanglement power and the high purpose of entanglement strength, and can are enough in water less for solution amount
Rapid dispersion in the presence of punching.
