The Journal of Textile and Clothing Science (JTCS) is a peer-reviewed (refereed) journal. Which is aimed at providing the platform to exchange information pertaining to all sectors of textile and the clothing industry among researchers, textile technocrats, fashion designers and industry experts. The journal focuses on scientific, technical, economical, managerial and all other aspects of textile activity at theoretical and experimental level. JTCS is aimed at publishing original research articles, review papers, short communications, and letters to the editor and book reviews catering the needs of both industry and academia.

Three diverse needle-punched nonwoven fabric tests were fabricated by fluctuating number of layers viz. 6, 8 and 10 with the end goal that the resultant areal density of fabric stays steady. Needle punched nonwoven fabric was fabricated from polyester staple fiber of length 80 mm. Other machine parameters like punch density (180 punches/cm2) and depth of penetration (8mm) were kept consistent. Exploratory outcomes demonstrate that with an expansion in number of layers there is bit by bit increment in fabric thickness yet the porosity and air permeability diminishes. Be that as it may, fiber orientation turns out to be more arbitrary which is fundamental for powerful filtration execution of the fabric. There is no impact of an adjustment in number of layers on the mechanical properties of fabric. An example having 10 layers has a superior filtration trademark that shows ideal thickness with wanted porosity and permeability with same areal density as that of different examples. 1. Introduction Nonwovens are the items made by parallel laid, cross-laid or heedlessly laid networks fortified by mechanical means or with the use of glues or thermoplastic fibers underutilization of warmth and pressure. The prominence of these fabrics is growing gigantically in perspective of its variable yet one of kind properties. Nonwoven fabrics are call as tailor-influenced fabrics as we to can produce the fabric with liked properties. Fabrics properties of nonwovens extend fresh to that soft-to-the-touch to brutal, hard to-tear to extraordinarily weak. This prompts a broad assortment of the things, for instance, nappies, channels, teabags, geo-materials; et cetera, some of which are solid and others are nonessential. Interchange properties are compressibility, adaptability. By applying distinctive culminations, the properties of nonwoven can be refreshed. They can be heat proof, hydrophobic, hydrophilic, wash and destructive protection and antagonistic to microbial. There are assorted process parameters that are required to be set while producing nonwoven fabric with any innovation. All these procedure parameters can influence the properties of delivered fabric. By changing the procedure parameter, we can without much of a stretch modify the properties of the nonwoven fabric. To get wanted properties in the last thing it is basic to streamline the procedure parameters. Numerous investigations were done on the * Corresponding author. Tel:+918856088180
