Document Summary
Chapter 4 study questions: explain why combed yarns would be more costly than carded yarns of the same. Yarns that are combed are costlier than carded yarns due to the method used to make cotton and cotton -blend spun yarns into finer fabrics. His involves cleaning the fibres and pu ngthem in parallel posi ons, while removing short fibres. With longer fibres le , the combed yarns are more uniform in length and have fewer speck and dirt impurities. thus, fabrics of combed yarns look better, feel smoother, and are stronger and more expensive. Comment on the use of novelty yarns for fabrics to be used for children"s wear. Novelty yarns are yarns that are not of uniform thickness throughout their length but have deliberate irregularities on their surfaces. They may be knots bumps curls or similar effects. Growth is the unrecovered stretch in textile fabrics.
