An experimental investigation of nonwoven filter cloth with and without reinforcement of woven fabric

In this experimental study, the effect of needling intensity and reinforcement fabric on some physical properties of needle‐punched nonwoven filters was investigated. The needle‐punched nonwoven filters with different needling intensities were fabricated with and without reinforcement fabrics. Recycled polyester fibers were chosen as raw materials, and acrylic fibers were used in the reinforcement fabrics. The variation of physical properties of filter fabrics, such as air permeability, thickness, mass per unit area, and bursting strength, was analyzed with respect to the needling intensities as well as the reinforcement materials. The results showed that the burst strength of the filters increased by using the reinforcement fabric and increasing the needling intensity until a critical level. Moreover, air permeability of filters decreased by using the woven reinforcement materials and increasing the needling intensity.     

The influence of calendering parameters on performance properties of needle-punched nonwoven cleaning materials including r-PET fiber

The aim of this study is to investigate the effect of calendaring process parameters on performance properties of needle-punched nonwoven materials including recycled polyester (r-PET) fiber. For this purpose; nonwoven materials produced by carding and needling processes with two different blend ratios have been calendered with different temperatures and roll clearances. The physical and performance properties of the samples such as thickness, bulk density, abrasion resistance, water absorption properties have been determined according to the standard test methods. The results derived from the tests were statistically evaluated by Design Expert^® software and the effects of chosen parameters on physical and performance properties of the samples were assessed. It was observed that additional thermal bonding process with calendering enhanced the performance properties compared to non-calendered samples and the excessive increase in calendering parameters yields to decrease in abrasion resistance and water absorption capacity.

Thermobonded Nonwoven Fabrics Made from Cotton/Synthetic-fiber Blends: Physical Properties

An investigation is described in which nonwoven fabrics were produced from 70/30 cotton/synthetic-fiber blends. They were thermobonded with a calender at different bonding temperatures but at constant nip pressure and production speed. All fabrics were made of the same bleached cotton fiber blended with 20 synthetic binder fibers. The mean fabric mass/unit area was approximately 60 g/m². The fabrics were evaluated for nine physical properties. The data were analyzed by using nested analyses of variance, univariate-mean-comparison tests, a multiresponse optimization procedure, a canonical-discriminant analysis, a regression analysis, least-squares mean-comparison tests, and analyses of covariance. All physical properties showed significant differences between fabrics and between bonding temperatures for each fabric composition. The optimal bonding temperature for each fabric composition was dependent upon the binder-fiber type. Significantly different relationships between fabric thicknesses and bonding temperatures occurred among fabric compositions. Differences among the fabric compositions were measurable in fabrics made from blended cotton/bicomponent fibers and cotton/biconstituent fibers. Relationships between machine and cross directions differed for breaking strength, elongation, and stiffness. These relationships also differed among fabric categories for breaking strength and stiffness. The best fabric for each physical property was related to the binder-fiber type. The more appropriate synthetic fibers for blending with cotton to produce the nonwoven fabrics with over-all optimum properties were: polypropylene fiber II, polypropylene fiber III, and bicomponent fiber III, made of 50/50 polyester-fiber core/polypropylene-fiber sheath.
