1. INTRODUCTION

It is similar to filament yarn production. From the chips storage, the polymer is vacuum-fed to a dosing station on top of the extruder. Inside the extruder, it becomes melted and homogenized. Passing a filter system and a spin pump, the melt is fed into the spin beam or spinnerets, which form a curtain of filaments. The filaments are cooled by means of a stream of air in a blowing area, drawn by aerodynamic forces and then transported to the downstream discharge channel. For nonwovens, instead of a further stretching process for filament yarns, the filaments are swirled around and then deposited on the wire mesh belt as a random nonwoven. This web is transferred to a bonding calender that uses heat and pressure to set such physical properties as tensile strength and elongation of the final product. After cooling, the material can be wound.

2. APPLICATIONS

Spunbonds are used mainly for hygiene products such as baby and adult diapers, feminine care, and medical products such as protective apparel. Spunbonds also are used more and more in technical applications. These are used mainly for construction, coating substrates, agriculture, battery separators or even disk covers.
I) Sanitary and medical
The use of spunbond web as a coverstock for diapers and incontinence devices has grown dramatically in the past decade. This is mainly because of the unique structure of spunbond, which helps the skin of the user stay dry and comfortable. Additionally, spunbond webs are cost effective over other conventional nonwovens. Spunbond web, as coverstock, is also widely used in sanitary napkins and to a limited extent in tampons.
In medical applications many traditional materials have been replaced by high performance spunbonded webs. The particular properties of spunbonded webs, which are responsible for medical use, are: Breathability; Resistance to fluid penetration; Lint free structure; Sterilizability; And, impermeability to bacteria.
