To hanyang a nonwoven fabric, first a web is made, and then it is tied (bonded together) to give strength. They commonly abandon nonwoven fabrics form the textile group. Conventional textiles are not able to meet the production cost and higher cost of upgradation along with demanding consumers in new fields of consumption.
Following the process, the web is bonded by passing it through two calendar rollers. In recent couple of years the nonwoven industry has emerged at a rapid speed, offering a huge range of products to several diversified fields. In the conventional fabric, the fibre is first made into yarns; on the other hand, nonwovens are manufactured sheets or webs directionally or randomly orientated fibres, bonded through resistance, solidity or sticking together into a fabric.
One-step process: In this process, the formation of web and bonding is poly-linen fabric conducted continuously. Usually, Nonwoven fabrics are made from two processes, a one-step or two-step.Usually people consider textile fabrics as the common categorization such as woven, knitted, braided or tufted constructions. Conversely, nonwoven fabrics hold some natural characteristics, which led them to be counted for non-usable in certain applications. The processes, spunbond and melt blown are considered under one-step.
Melt blown process: The thermoplastic fibers are driven onto a collector screen to make a web. At present, many research and development has been conducted on enhancing the characteristics of nonwoven fabrics. The combination of fibers fixing and snaring, results bonding. Nonwovens are also entering into some astonishing fields, with making its mark in fashion apparel also
