Investigation Barrier Properties of Linear Low Density Polyethylene (LLDPE) Spunbond Fabrics

Abstract

Nonwovens have a growing worldwide market that has a vital proposition in many sectors such as geotextile, medical textile, automotive industry etc. which are supported by technological developments according to the desired characteristics. Among the production methods of the nonwovens, spunbond nonwovens made of polyprophylene (PP) have disposable and durable functional properties and are preferred especially in the field of disposable hygiene textiles. Although the fabric volume market of PP spunbond nonwovens is expected to grow rapidly owing to personal hygiene awareness with an increase in the aging population and regulations for hygiene, polyethylene spunbond nonwovens can probably share the application area due to having a lower melting point and easy processable. In this study, the effect of the weight of linear low density polyethylene (LLDPE) spunbond nonwovens on barrier properties such as resistance to air flow and water were evaluated. Results showed that weight has a statistically significant effect on air permeability and hydrostatic head pressure.

“…A spun-bonded nonwoven must have the appropriate parameters to be effective in its application. Breaking force, for example spun-bonded nonwoven made from non-biodegradable polymers, i.e., linear low-density polyethylene was 33 N [102]. In the commercial market, nonwoven fabrics made of spun-bonded polypropylene are available with a braking force of 10-200 N and an elongation of 50-300%, depending on their The obtained nonwoven was characterized by physico-mechanical parameters listed in Table 1.…”
