Spunbond
Nonwoven fabrics formed from spunlaid and meltblown and bonded by spunbond technology. The resine used for its production is commonly PP; due to the nature of the spunbond fabrics they are widely used for:
- Baby diaper (single fabric or laminations).
- Adult incontinence diaper (single fabric of laminations)
- Fem care products (sanitary napkins, panty liners, breast-feeding liners)
- Medical applications
- Fruits and vegetables protection packing
The main physical properties for this kind of fabrics are their excellent tension resistance, low elongation % and the ability of perform at low basis weight among others.
According to the machinery used in its production and the requests from our customers, we can offer special applications such us: Aloe vera, super soft, hydrophilic, antistatic.
To understand better this process we have to divide it into two: web forming and web bonding.
Formación: in this kind of technology it is used either spunlaid or meltblown. Formation is commonly known as spunmelt..
- Spunlaid PP chips are melted in spinnerets and turned into continuous filaments that fall to a conveyor system and dry to then move to bonding station. While the filaments are on the conveyor they receive the name of web.

- Melblown is the same as spunlaid but air cool and cut the filaments when they come out of the spinnerets, these fall randomly to the conveyor and then move to bonding station.

In this photo we can see the fibers of an expanded SSMMS material, the meltblown staple fibers in the middle and the spunlaid continuous fibers at the ends.
