A kind of ultra-soft anti-reverse osmosis kapok diaper material and preparation method thereof

Abstract

The invention discloses a super soft and anti-reverse osmosis kapok diaper material. The material is composed of two fiber nets with different pore sizes in gradient. It is viscose / wood pulp wet-laid fiber web; its preparation method is as follows: 1) uniform kapok / viscose spunlace fiber web is initially prepared by spunlace process; Viscose / wood pulp wet-laid fiber web; ③The viscose / wood pulp wet-laid fiber web output from the inclined web and the kapok / viscose spunlace fiber web output from the lower web are then compounded by flat web and drum spunlace; ④ The composite fiber web is dried in a drying cylinder and hot air combined, and after dehydration, a super-soft anti-reverse osmosis kapok diaper material is obtained. The advantages of the present invention: the excellent characteristics of kapok are fully exerted through the non-woven process, and the production cost is low, light and soft, dry and breathable, antibacterial and anti-mite, fast penetration and absorption, not easy to reverse osmosis, safe and environmentally friendly.

Description

technical field [0001] The invention relates to a super soft anti-reverse osmosis kapok diaper material and a preparation method thereof, and the diaper material is suitable for the field of sanitary materials. Background technique [0002] With the development of the economy and the improvement of people's living standards, the market demand for non-woven fabrics that are closely related to people's lives and work is also increasing. As the main sanitary material, diapers have quickly replaced the status of traditional diapers with their advantages of convenience, hygiene and comfort. Modern diapers are a liquid suction control system established by multiple layers of non-woven materials. , The surface layer is the first layer for diapers to achieve liquid absorption. Its main function is to absorb and transfer liquids such as urine to the next layer of diapers. It is required to be delicate and soft, keep dry, and not irritate the skin. [0003] At present, the diaper sur...

Patent CN107630319A discloses a partially hydrophilic non-woven fabric and its production method. It adopts a hot roller to carry out concave-convex treatment on the hydrophobic non-woven fabric, and coats the hydrophilic agent on the depression. When it is used for the surface layer of diapers Body fluids that touch the surface of the non-woven fabric will bypass the hydrophobic protrusions and be absorbed by the absorbent layer in the hydrophilic depressions, so as to obtain a dry surface layer, but the concave-convex structure formed on the one hand will cause discomfort to the skin On the other hand, under the pressure of the human body, the concave-convex structure will also be destroyed, so that the water in the depressions will easily seep into the skin, and it uses chemical fibers and chemical finishing agents, which are not good enough in biological safety and are not conducive to sustainable development.
