Full-degradable skin-care high-softness fine-denier cellulose spunlace wet tissue material and production method for wet tissue

Abstract

The invention relates to a full-degradable skin-care high-softness fine-denier cellulose spunlace wet tissue material which is relatively soft, fine and skincare in a wet-state using process, cannot relatively slide and can be fully biodegraded, and a production method for wet tissue. The wet tissue material is prepared by mixing the following raw materials by weight percent: 10-80% of 5-15 mm cellulose fibers with the fineness of not more than 0.9 dtex and 90-20% of wood pulp subjected to defibrination and fibrillation. The wet tissue material has the advantages that firstly, the cellulose fibers with the fineness of not more than 0.9 dtex is deeply dispersed by adopting a high-pressure defibering technology, so that a surface layer of the spunlace wet tissue is relatively fine and soft, and a precedent that the cellulose fibers can be separately combined with other materials-spunlace within one minute is set; secondly, the raw materials can be fully degraded without residues and are environment-friendly; thirdly, wood pulp fibers serve as a framework of the spunlace wet tissue, so that the strength of the cellulose fiber material can be enhanced while the cost is reduced; fourthly, the loss rate of the fibers during production is reduced to be 1-3% from 6-8%, so that the utilization rate of the raw materials is greatly increased.

Description

technical field [0001] The invention relates to a fully degradable skin-relieving high-soft and fine-denier cellulose spunlace wet tissue that is more soft, delicate and skin-friendly in the wet state, does not produce relative slippage, and the final product can be 100% biodegradable. The material and the manufacturing method of the wet tissue belong to the field of wet tissue manufacturing. Background technique [0002] At present, traditional wet wipes and other wiping spunlace materials adopt the processing technology of dry carding to form spunlace entanglement. Since the processing fineness of fibers in the dry carding process is about 1.5-3.0 decitex, fibers with a fineness of less than 1.4 decitex It is difficult to comb and form, and it is easy to cause various problems such as wire wrapping and fiber breakage during carding, and the thicker fibers make the final wet wipe product insufficient in fineness and softness, resulting in wet wipes when used as wet wipes. ...

Problems solved by technology

[0002] At present, traditional wet wipes and other wiping spunlace materials adopt the processing technology of dry carding to form spunlace entanglement. Since the processing fineness of fibers in the dry carding process is about 1.5-3.0 decitex, fibers with a fineness of less than 1.4 decitex It is difficult to comb and form, and it is easy to cause various problems such as wire wrapping and fiber breakage during carding, and the thicker fibers make the final wet wipe products insufficient in fineness and softness, which leads to wet wipes when used as wet wipes. Because the surface of the wipe has many concave and convex gaps, when using the wet wipe, the relative slip between the wet wipe and the skin is prone to occur and cause displacement, which brings a lot of inconvenience to the user
