Two-sided hydrophilic punched non-woven fabric special for sanitary consumables and production method thereof

Abstract

The invention discloses two-sided hydrophilic punched non-woven fabric special for sanitary consumables. The non-woven fabric comprises a first non-woven fibrous layer and a second non-woven fibrous layer, wherein the first non-woven fibrous layer and the second non-woven fibrous layer are bonded together through hot rolling, a plurality of conical through holes are formed in the first non-woven fibrous layer and the second non-woven fibrous layer through pressing, the conical through holes are arranged in the first non-woven fibrous layer and the second non-woven fibrous layer in order, and the distribution rate of the conical through holes is 30-50%. The invention also provides a production method of the two-sided hydrophilic punched non-woven fabric special for sanitary consumables. The production method comprises the steps of feeding, melting extrusion, extrusion spinning, air laying, double-layer fiber net hot rolling, two-sided hydrophilic treatment, drying treatment, punching treatment and coiling and packaging. The steps are simple, the hydrophilic effect and liquid permeation effect of non-woven fabric are improved, liquid accumulation and long-time contact between liquid and skin are avoided, and the technical problems that non-woven fabric for sanitary consumables is poor in permeability and hydrophilia are solved.

Description

【Technical field】 [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a double-sided hydrophilic perforated special nonwoven fabric for sanitary materials and a production method thereof. 【Background technique】 [0002] Nonwovens for hygiene materials are used in medical and daily necessities, including medical masks, diapers, sanitary napkins, etc. These products require high water absorption and liquid conductivity, and the use of non-woven fabrics for sanitary materials is increasing day by day. The quality of products made of non-woven fabrics for sanitary materials is also uneven, and the liquid absorption capacity is poor. The longer residence time on the cloth surface makes the skin contact with the liquid for a long time, which affects the health of the skin. It is used in the production of baby diapers, which will affect the healthy growth of the baby. In the process of use, there are often situations of uneven fluid conduction...
