Abstract
Dispersible and degradable wood-pulp composite nonwoven fabric belongs to the technical field of cleaning products and comprises a wood-pulp fiber layer and a nonwoven fiber layer, wherein the wood-pulp fiber layer is combined at one side of the nonwoven fiber layer; and the nonwoven fiber layer adopts 'natural fiber' or 'artificial fiber'. The dispersible and degradable wood-pulp composite nonwoven fabric is characterized in that the fiber length of the wood-pulp fiber layer is 2-5mm, while the fiber length of the nonwoven fiber layer is 25-35mm. The technical scheme is as follows: through the reasonable selection of the fiber length of the wood-pulp fiber layer and the fiber length of the nonwoven fiber layer, the dispersible and degradable wood-pulp composite nonwoven fabric can ensure not only excellent dispersible and degradable effects but also the tension-resisting, tear-resisting and wear-resisting strength; no scraps fall off and excellent water absorption property is embodied; and when serving as kitchen and toilet products, the dispersible and degradable wood-pulp composite nonwoven fabric can not block a pipeline after being discarded, and has extremely good environment-protection effect.
Description
Technical field
The utility model belongs to the cleaning supplies technical field, is specifically related to a kind of degradable wood pulp composite non-weaving cloth that breaks up.
Background technology
The background technology hurdle of the patent specification of the compound water brushing of recommending as utility model patent Granted publication CN201553877U with wood pulp fiber layer (application that the applicant proposes) is described, though the pure cleansing tissue that uses wood pulp fibre to make by traditional paper technology has the strong point of environmental protection, but there are following two place's shortcoming at least: the one, owing to be subjected to the influence of the self-characteristic of wood pulp fibre, tensile strength, tearing toughness and ABRASION RESISTANCE fragility, and easily fall slag and fall bits; The 2nd, when making the similar hygrometric state product of Moistured towel paper, facial mask or other, the chemical assistant that is added easily with the reaction of paper product material production, the security of influence use.And above-mentioned patent is also pointed out, makes the shortcoming that the said goods can be eliminated the made before-mentioned products of wood pulp fibre with the pure chemistry fiber, but loses environmental protection and use in the kitchen guarding and very easily cause drainage pipeline to stop up.
The technical scheme that above-mentioned patent is recommended is: wood pulp fiber layer is combined with the textile fabric layer of being filled the post of by chemical fibre, natural fabric or blended fiber (chemical fibre and natural fabric), embodied the mutual supplement with each other's advantages between wood pulp fibre and the textile fabric ultimate attainmently, specifically can walk to the 3rd page of the 1st row referring to the 1st page of inverse the 2nd of this patent specification.
But the applicant thinks that there is shortcoming in the reasonability that above-mentioned patent scheme is selected the length of wood pulp fibre and textile fabric, because the length of fiber is long, can influences and can break up effect and degradable and soaking effect.Otherwise, too short as the length of fruit fiber, then tension and tearing toughness are produced adverse influence.Therefore, how between the breaking up of the length of reasonably selecting wood pulp fibre and textile fabric and goods, degradable and physical strength, find rational equalization point to become the problem that industry is paid close attention to and expectation solves.For this reason, the applicant has carried out trial lastingly and repeatedly, and technical scheme described below produces under this background.
Summary of the invention
The task of invention is to provide a kind of and had both helped raising to break up and degradation effect, help guaranteeing tension and anti tear physical strength again, also be of value to the good water imbibition of guarantee, and can be to the degradable wood pulp composite non-weaving cloth that breaks up of drainage pipeline obstruction after discarding.
Task of the present utility model is finished like this, a kind ofly break up degradable wood pulp composite non-weaving cloth, comprise wood pulp fiber layer and fibrous nonwoven layer, wood pulp fiber layer is incorporated into a side of fibrous nonwoven layer, wherein: described fibrous nonwoven layer is " natural fabric or artificial fibre; be characterised in that: the length of described wood pulp fiber layer is 2-5mm, and the length of the fiber of described fibrous nonwoven layer is 25-35mm.
In a specific embodiment of the present utility model, the thickness of described wood pulp fiber layer is bigger than the thickness of described fibrous nonwoven layer.
In another specific embodiment of the present utility model, the thickness of described wood pulp fiber layer equates with the thickness of described fibrous nonwoven layer.
In another specific embodiment of the present utility model, the thickness of described wood pulp fiber layer is 8-40 μ m.
In another specific embodiment of the present utility model, described natural fabric is cotton fiber, soybean fiber or milk fibre.
Also have in the specific embodiment of the present utility model, described artificial fibre is a viscose.
More of the present utility model and in specific embodiment, the surface of described wood pulp fiber layer has by literal, letter, pattern or it is in conjunction with the formed first imprinted pattern zone.
In of the present utility model and then specific embodiment, the surface of described fibrous nonwoven layer has by literal, letter, pattern or it is in conjunction with the formed second imprinted pattern zone.
Of the present utility model again more and in specific embodiment, the described first imprinted pattern area of the pattern is positioned at central part, edge or central authorities and the edge on the surface of described wood pulp fiber layer.
In again of the present utility model and then specific embodiment, the described second imprinted pattern zone is positioned at central part, edge or central authorities and the edge on the surface of described fibrous nonwoven layer.
The technical scheme that the utility model provides is owing to done rational selection to the length of the fiber of wood pulp fiber layer and fibrous nonwoven layer, can guarantee to have good broken up degradable effect, can ensure tension, anti tear and scuff resistance again, and the slag that can not drop bits and the water imbibition that can embody excellence, when using as the kitchen guarding, can not cause obstruction after discarded, and have ultimate attainment environment protecting pipeline.
