FASH 290 Lecture 11: FASH 290 board notes- chapter 12 - Weaving
Document Summary
Fabrics are made from: solutions fibers yarns composites. Wovens produced on a loom two or more yarn sets interlaced at 90 degrees. Firmer, more rigid than knits, laces, braids. Oldest method, most widely used, fabrics ravel from all four cut sides, fray, have grain, elasticity is low, same weave structure can look different due to yarn size/type/twist/count, color, print, finish. Shedding : picking , beating-up , take-up . Patterning capabilities: -different types of pattern making looms =dobby, jacquard, lappet, doup. Computers and electronic monitors automation helps reduce defects. Loom efficiency -shuttle looms are being replaced with faster, quieter, more versatile looms (see below). 1. shuttleless: more common now and quicker and quieter than shuttle looms (which were industry standard) Count: warp x filling (40 x 50) can be given as total if balanced (45 x 45 =90) Balance: ratio warp to filling balanced= 1:1 unbalanced = 2:1 or 1:2 balanced 78 x 78 unbalance 144 x 76.
