Why use polypropylene non-woven fabric

Polypropylene non-woven fabric is a kind of polypropylene as raw material, after melting, spinning, web, preparation of adhesive and curling a non-woven fabric. Because of its simple process, high yield, non-toxic harmless to the human body. So widely used sanitary materials, medical supplies, bedding, sofa, bags, shoes and clothing, and other fields. Polypropylene non-woven fabrics with low density, texture soft, fluffy plump, non-toxic, breathable, etc, on the water, waterproof modification for disposable sanitary products of the surface and bottom, to give the product function of hydrophilic, waterproof and breathable, can be used in hot rolling of infant disposable products such as diapers and type polypropylene non-woven fabric is using spinning, drawing, web, such as hot rolling process preparation, polypropylene fiber silk has many mesh and between pore, has good air permeability, low cost, convenient processing, low environment load, etc. With the increase of non-woven booker heavy, become dense mesh structure, decrease of porosity, the permeability is stronger; When the gram weight range is between 25, g/m2, MVRT 2100 g/( m2. 24h) ； In the preparation of polypropylene non-woven disposable absorbent towels MVRT 2080 g/( m2. 24h) , permeability and comfort is better than that of PE breathable membrane, has a good cost performance. Hot rolling type polypropylene non-woven fabric in the process of preparation, extruding and drawing speed is generally remain unchanged, fiber diameter basic remain unchanged, increase the gram weight is by reducing the speed of net belt to the shop. Accumulation of per unit area between populations, silk fiber pore become smaller, the greater the gram weight of non-woven fabric, the greater the thickness, the smaller the porosity, permeability variation. With the increase of non-woven booker heavy, mesh structure becomes more and more dense, fiber between porosity decreases. Under the condition of invariable when spinning and drawing conditions, basic remains the same, the diameter of the fiber web drawing at a slower pace, accumulation of per unit area increased, the number of fiber polypropylene silk accumulation is the more densely populated, non-woven fabric thickness increases, so the gram weight, the greater the porosity is smaller.
