TS 111 Lecture Notes - Lecture 1: Twill, Ultimate Tensile Strength, Knitting Machine
Document Summary
Groups of fibers twisted together to form a continuous strand. Necessary for the creation of woven fabric, knitted fabrics, and knitted garment. Made up of two or more fiber types. Cotton starts at plant, goes through cleaning, create sliver, then we elongate it so we can get it into a yarn. Fat places in yarn is slub-- depends what we will use for if it matters if it is a slub yarn or not. Standard fabrics are usually cheaper while further processed fabrics are usually more expensive. Better regularity, improved abrasion resistance (esp. high twist) Higher production rates (10x ring spun), less expensive. S or z: direction of the fiber"s twist. The direction of twist can have an affect on the look and feel of the fabric. Spun yarn may have ends of fibers sticking out b/c they are short, filament fibers won"t b/c they are longer fibers.
