PP Spunbond Nonwoven Fabric Specialty

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Jul 07, 2017

Belly believe that many friends on the PE / PP double sets of spunbond cloth is not yet understood, PE / PP double group of spunbond cloth is made of PE polyethylene and polypropylene polypropylene spunbond produced by a double core structure. PE / PP double sets of spunbond cloth with a soft touch feel smooth, heat together, PP Spunbond Nonwoven Fabric good tension, high tensile strength, safety, PP Spunbond Nonwoven Fabric no added no stimulation and other characteristics of today to come to the specific analysis of the Safe without adding non-irritating features.

Now all the safety awareness is improving, PP Spunbond Nonwoven Fabric consumers in the purchase of diaper on the safety of a higher demand. Then the actual production and sales of diaper, you need to have a better non-woven safety.

We all know PP spunbond non-woven fabrics, PP Spunbond Nonwoven Fabric in order to achieve better softness, you must add a variety of additives. However, PP Spunbond Nonwoven Fabric PE / PP double sets of spunbond in the application is without any addition and modification under the premise of achieving better heat and softness.

PE / PP bicomponent fiber is a core-sheath composite structure, PP Spunbond Nonwoven Fabric the core material for the polypropylene (PP) (melting point of about 165 ℃), cortical material for the polyethylene (PE) (melting point of about 130 ℃). Hot melt melting, the use of lower temperature, PP Spunbond Nonwoven Fabric cortical melt bonding, core properties remain unchanged. Adhesive with the glue when the effect is not good damage to the sticky glue, can prevent composite layer, anti-corrosion creep. No need to add softeners, PP Spunbond Nonwoven Fabric slip agents, elastomers and other additives.

PE / PP two-component spunbond production process without adding additives in the characteristics of the diaper just meet the security needs. In the diaper storage process, PP Spunbond Nonwoven Fabric there is no any additives precipitation, will not affect the adhesion of hot melt adhesive.

PP spunbond nonwovens to the rapid development of the important reason is its simple and quick manufacturing methods, low product cost, quality and stability in the market competitiveness. Producers in order to reduce the amount of polypropylene, reduce carbon dioxide emissions, but also in the production process to add calcium carbonate filled masterbatch in the price, processing, production costs, PP Spunbond Nonwoven Fabric physical indicators, etc. PP Spunbond Nonwoven Fabric occupy more advantages. From this point on the greatly expand the PP spunbond non-woven applications and sustainable development, energy-saving emission reduction is the inevitable trend of the development of spunbond nonwovens industry. Today we will introduce the calcium carbonate in the non-woven process and its application ~

Spunbond non-woven fabrics used in the production of raw materials for the high melt index of polypropylene, and calcium carbonate filled masterbatch mixed evenly from the hopper into the screw extruder melt into the continuous pre-filter, and then into the spinning box The Melt through the metering pump into the spinning head, by the metering pump accurate measurement, the melt quantitative delivery to the spinneret, PP Spunbond Nonwoven Fabric and through the nozzle hole to form a continuous melt flow, PP Spunbond Nonwoven Fabric that is, raw fiber. The primary fibers are then cooled by a cold air and drafted to form a tow. Filament beam swing through the pendulum roller, evenly placed in the operation of the network into the screen on the screen.
