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

Öz

Nonwovens are 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 functions 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. This study evaluates the effect of the weight of linear low density polyethylene (LLDPE) spunbond nonwovens on barrier properties such as resistance to air flow and water. Results showed that weight has significant effect on air permeability and hydrostatic head pressure.
