Abstract
The utility model belongs to the technical field of cleaning supplies, and provides degradable biological fiber wiping cloth. The degradable biological fiber wiping cloth comprises a wood pulp fiber layer and polylactic acid fiber layers combined on one surface or two surfaces of the wood pulp fiber layer. Wood pulp fiber which forms the wood pulp fiber layer and polylactic acid fiber which forms the polylactic acid fiber layers are mutually hooked and embedded. Due to combination of the polylactic acid fiber layers and the wood pulp fiber layer, the wiping cloth not only can reflect the ideal mechanical and physical properties, perfect drapability, excellent smoothness, natural bacteriostatic performance and good strength of the polylactic acid fiber, but also can compensate for the defect of poor hydroscopicity of the polylactic acid fiber, can be used as compost and processed after being discarded and does not damage the environment. Due to the fact that the polylactic acid fiber overcomes the defects that the wood pulp fiber which has good water absorption effects is poor in fiber softness and low in strength, and scraps easily fall from the wood pulp fiber, the degradable biological fiber wiping cloth not only has the advantages of being low in cost, high in strength, good in water absorption performance, soft in touch feel, and free from fuzzing and scrap falling, but also is economical and cheap.
Description
Technical field
The utility model belongs to the cleaning supplies technical field, is specifically related to a kind of degradable biological fiber cleaning wiping cloth.
Background technology
Though adopt the paper product class Wiping material of traditional paper technology production to have environmental protection and cheap strong point, but intensity low (particularly wet strength very fragile), tear-resistant effect is poor, not wear-resisting and easily fall bits or the like is its deficiency, thereby has limited the Application Areas of this Wiping material such as cleansing tissue to a great extent.
In order to satisfy special dimension to the cleaning wiping cloth application requirements of (also claiming Wiping article, as follows), the on-woven cleaning wiping cloth is arisen at the historic moment.Nearly two during the last ten years, the on-woven cleaning wiping cloth relies on its good homogeneous and mechanical and physical performance and soft and cheap advantage and occupied crucial position in Wiping article, has become requisite cleaning supplies in industrial production and the people's daily life and is widely used in the wiping of wiping, automobile and parts thereof to electronic product and wet tissue etc.
Aforementioned on-woven cleaning wiping cloth in the prior art is that raw material processes through the carding and the water thorn (promptly Hydroentangled) of on-woven product processes with fibers such as terylene, viscose glues mainly.Because this type of cleaning wiping cloth not only needs to consume a large amount of petroleum base fiber or viscose glue, and in the process of these type of cleaning supplies of preparation, exist the drawback of high pollution and high energy consumption (for example can produce a large amount of carbon disulfide, hydrogen sulfide and waste water and dregs etc. in the viscose glue production process, the industry that belongs to country's restriction development), therefore, run counter to the recycling economy of advocating at present, energy-conservation and environmental protection spirit.
In recent years, along with global range is increasing to the consumption of on-woven cleaning wiping cloth, follow and the problem of following two aspects of arriving also becomes increasingly conspicuous; The one, cause non-renewable petroleum resources deficient day by day; The 2nd, ecological environment is impacted in discarded back because of being difficult to degraded.
In disclosed Chinese patent literature, can be seen in the biological fiber cleaning wiping cloth that helps degrading, for example CN201553877U recommends to have " the composite spunlaced cloth with wood pulp fiber layer ", it is to be made of wood pulp fiber layer and textile fabric layer, and the material of textile fabric layer is chemical fibre and/or natural fabric, patent has exemplified wood pulp fibre and polyster fibre, soybean fiber with wash fiber, bamboo fibre and milk fibre, four kinds of combinations of viscose and cotton fiber, in four kinds of combinations that this patent exemplifies, only the combination of bamboo fibre and milk fibre has favorable environment protection.But, owing to milk fibre is animal protein fibre and needs to separate, purify, obtain spinning solution with polyacrylonitrile blended, crosslinked, grafting through dehydration, de-oiling, degreasing that therefore, cost is higher.
And for example publication number CN101352942A provides " total biological degradation nonwoven cloth for medical treatment/industry and production technology thereof ", and it is to be made of wood pulp fiber layer spunlace non-woven cloth base cloth layer, and the material of spunlace non-woven cloth base cloth layer is polyvinyl alcohol (PVA).Owing to vinal obtains through formaldehyde treated, and polyvinyl alcohol therefore not only make fine process complexity, and cost is higher originally as organic compound.
Publication number CN101220534A introduces for another example " a kind of full-biological degradation nonwoven cloth material ", this patent is to be basic material with carbon dioxide-ethylene oxide copolymer or carbon dioxide-epoxy propane copolymer, add biodegradable material such as PLA or poly butyric ester, this patent scheme does not have referential technical meaning for biological fiber Wiping material and preparation thereof, specifically can walk to the 6th page for the 5th page the 10th referring to the specification of this patent.
In above-mentioned patent documentation, only mentioned PLA by CN101220534A, PLA is a kind of biodegradation material, make by the starch material that reproducible plant such as corn extract, and then the acid fiber by polylactic of being made by PLA can not exert an influence to soil and water system because of discarded causing after making goods, because it can be decomposed into carbon dioxide and water through microbial action, even when burning, can not distribute toxic and harmful, can not pollute, so acid fiber by polylactic is a kind of ecological fiber of sustainable development.In addition, acid fiber by polylactic has favorable mechanical physical property, ultimate attainment drapability, excellent smooth property, natural bacteriostatic and desirable brute force.But because PLA itself do not absorb water, the therefore water absorbing properties extreme difference of the Wiping material of making by pure acid fiber by polylactic, and whether the excellence of water absorbing properties considers the Wiping material important indicator exactly.Perhaps because the shortcoming of PLA water imbibition difference, thereby limited its application in the production wipe product to a certain extent.Therefore, the problem that how to remedy the water imbibition difference of acid fiber by polylactic suffers from industry for a long time, and the applicant has made good try for this reason, finds a way to resolve the problem finally, and technical scheme described below produces under this background.
Summary of the invention
