Embodiment 1
[0019] Preparation of ultra-soft barrier melt-blown fiber layer:
[0020] Polypropylene is used as raw material to form an ultra-fine melt-blown nonwoven fabric after being heated and melted by a single-screw extruder, a filter device, a metering pump, a die head, hot air drafting and laying. In order to ensure the elongation and elasticity of the melt-blown fiber , the process parameters are as follows: the metering pump is 13rpm, the temperature of the 22 heating zones of the die is 271°C, 270°C, 274°C, 271°C, 268°C, 269°C, 269°C, 268°C, 270°C, 270°C, 270°C , 270°C, 270°C, 270°C, 270°C, 270°C 270°C, 270°C, 270°C, 270°C, 270°C, 270°C; drafting wind temperature 240°C, DCD value 150mm. The ultra-soft barrier melt-blown fiber layer is transported to the position before the hydroentangling process through the unwinding device.

Abstract
The invention relates to a supersoft wet-method spunlaced composite non-woven fabric for infant and a production method. A supersoft barrier melt-blown fiber layer and a short-cellulose fiber layer are combined through a wet-method spunlaced composite technology, the lower layer is the melt-blown fiber layer and has the advantages of being soft in hand feel, good in barrier property, not prone to deformation and the like, the upper layer is the short-cellulose fiber layer with the pulp short fiber as the main part, the upper layer and the lower layer are planted and entangled in melt-blown fiber through a high-pressure spunlacing effect, and the non-woven fabric composite which has an embossment pattern and has the advantages of being good in water absorption property, supersoft and free of flock falling, having the barrier property on one side and the like is obtained by means of a hot rolling technology through hot air type through-drying. The product prepared through the non-woven fabric composite has the advantages of being rapid in water absorption, supersoft in hand feel in a wet state, not prone to deformation, capable of keeping the decorous feeling and the melt-blown side effective barrier property, free of any additives and the like, is incomparable by ordinary spunlaced non-woven fabric products and sanitary paper and is good in application prospects.
Description
technical field [0001] The invention relates to a spunlace non-woven fabric for wiping infants and young children. The non-woven fabric is compounded by superfine melt-blown fibers and short cellulose fibers through a wet process, and belongs to the field of non-woven fabric manufacturing. Background technique [0002] In my country, 20-30 million babies are born every year, and there are about 80 million infant consumer groups aged 0-4. Under the guidance of the national two-child birth policy, in the next 10-20 years, the birth rate of babies will enter a period of rapid growth, and the baby wet wipes and other supplies markets will also show strong development prospects. According to the latest analysis report of a North American non-woven fabric industry association on the North American wipes market, personal care wet wipes account for about 600 million US dollars in the North American wipes market, and sales of household cleaning wipes account for about 1.3 billion US ...
