3. Types of Non-wovens: There are many types of non-woven but basically two types of non-wovens are very common: (a) Felts (b) Bonded fabrics a. Felts: Felts as defined by ASTM are: A structure build up by the interlocking of fibers by a suitable combination of mechanical work, chemical action, moisture and heat without spinning, weaving or knitting. They may consist of one or more classes of fibers (main fiber type is wool).

Grain perfection is another factor which may deform the silhoutte of the garment. These factors must be given due considersation before cutting. 11.2 IMPORTANCE OF GRAIN: Grain refers to the direction of yarns in fabric. Woven fabrics are made up of lengthwise and crosswise yarns interlaced at right angles to each other. The lengthwise or warp yarns are usually heavier or strong and highly twisted yarns. The lengthwise direction of the cloth should hang straight down on the figure from the neck to the waist, from the armhole to the elbow, from the waistline to the bottom of the shirt. Grain is important in the small places as well as the main pieces of a garment. It is helpful to have a crosswise grain line drawn on such pattern pieces as sleeves, yokes and collars.
