Fabric engineering is the process of converting a yarn or multiple yarns into a new material. These may be achieved by different processes but mainly from three: non-woven, knitting and weaving. Nowadays these processes due to technological advances are able to be used in mass production for several materials in the industry. These include automobiles, bags, bedding, construction office supplies, medical, swimwear, sweaters, tops, jackets, seat covers and technical textiles. The production of these garments sometimes is the end product, however, there are many products that require several layers or additional processes to acquire the final conditions need it for that specific product. The production of this fabrics is based on the parameters set by the yarns used, these may come from a different background such as animal, synthetic, plant and mineral. Non-woven Fabric Formation: A nonwoven is a manufactured sheet, web or batt of directionally or randomly orientated fibers, bonded by friction, cohesion, and adhesion. From this it is excluded paper and products which are woven, knitted, tufted, stitch-bonded, incorporating binding yarns or filaments. These fibers may be natural or man-made, also may be stapled or continuous filaments. This type of fabric has several uses in the industry due to great advantages such as high production rate, low cost and easily engineered to meet/ use requirements. Can be seen in automobiles, bags, bedding, construction office supplies, and medical supplies. To create this fabric there must be certain parameter within the fiber in order to have an effective product. These must be fiber type, fiber linear density, fiber orientation, areal density and bonding parameters. The non-woven process can be divided by fiber preparation, fiber web formation, bonding, and finishing. There are several fiber web formation processes, some of them are dry-lay, wet-lay, spun-lay and melt blowing. Weaving: Is the process of converting two sets of orthogonal yarns to woven fabrics. The machine in charge of this merging process is in need of certain parameters depending on the given fabric desired to produce. These parameters, which influence the fabric properties such as weight, strength, and drape, are: wrap density, pick density, wrap yarn number, filling yarn number, wrap yarn crimp, filling yarn crimp and weave design. The machine always performs primary cycled motions that are shedding, filling beat-up and wrap plus fabric control motion. The secondary cycled motions are warp stop, filling stop, wrap protector, filling selection, leno motion, tuck-in motion and automatic weave or pattern change. Knitting: Knitting is the process of converting a yarn or set of yarns into knitted fabrics. A knitted fabric is formed by interloping the yarn(s). The knitted loops are arranged in vertical and horizontal sets of intermeshed loops to form an integrated structure. The vertical set of loops is called a wale and the horizontal set of loops is called a course. It is to the industry knowledge that 31% of the worldwide fiber production is converted into fabrics via knitting. Some of the end uses are swimwear, sweaters, tops, jackets, seat covers, technical textiles and medical textiles. There are two types of fabric classification within the knits: weft knits and wrap knit. Wrap knit is formed from the wrap sheet while the weft knit is formed from the wound packages. There are some structural parameters that influence the process making of a knitted fabric. These are wale, course, wale density or count, course density or count.
