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

Embodiment 1

[0015] Embodiment 1: with reference to attached figure 1 . A fully degradable skin-friendly, high-soft and fine-denier cellulose spunlace wet tissue material, composed of 5-15mm cellulose fibers with a ratio of 10-80% and a fineness of less than or equal to 0.9 decitex 1 and a ratio of 90-20% after refining and separating the silk broom It is made by mixing 2 melted wood pulps. The fineness is less than or equal to 0.9 decitex 5-15mm cellulose fiber 1 and 90-20% wood pulp that has been refined and divided into silk brooms 2 mutual disordered hydroentanglement structure to form a fully degradable skin-friendly high-soft fine-denier cellulose hydroentanglement wet towel material. The 5-15mm cellulose fiber 1 with a fineness less than or equal to 0.9 dtex refers to viscose fiber and flat viscose. The surface of fully degradable soft and fine denier cellulose spunlace wet wipes is rich in -OH groups and sawtooth structure.

Embodiment 1-1

[0016] Example 1-1: On the basis of Example 1, a fully degradable soft and fine denier cellulose spunlace wet tissue material is composed of 5-15mm cellulose fiber 1 with a ratio of 10% fineness less than or equal to 0.9 decitex and 90% of the ratio is made by mixing wood pulp 2 that has been refined and segregated. The fineness is less than or equal to 0.9 decitex 5-15mm cellulose fiber 1 and 90% wood pulp that has been refined and divided into silk brooms 2 mutual disordered spunlace entanglement structure to form a fully degradable skin-friendly high-soft and fine-denier cellulose spunlace wet tissue material .

Embodiment 1-2

[0017] Example 1-2: On the basis of Example 1, a fully degradable soft and fine denier cellulose spunlace wet tissue material is composed of 5-15mm cellulose fiber 1 with a proportion of 80% fineness less than or equal to 0.9 decitex and The 20% ratio is made by mixing wood pulp that has been refined and separated. The fineness is less than or equal to 0.9 decitex 5-15mm cellulose fiber 1 and 20% of the wood pulp that has been refined and divided into silk brooms 2 mutual disordered spunlace entanglement structure to form a fully degradable skin-friendly high-soft and fine-denier cellulose spunlace wet tissue material .

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. ...
