Brannock Device shoe sizes of men, women, and children; they also produce specialized models for fitting other types of footwear. Brannock Device The Brannock Device is a measuring instrument invented by Charles F. Brannock for measuring a person's shoe size. The son of a shoe industry entrepreneur, Brannock attended Syracuse University, New York. Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, patenting his first prototype in 1925 and an improved version in 1927. The device has
Sizing — of the yarn will improve and the hairiness of yarn will decrease. The degree of improvement of strength depends on adhesion force between fiber and size, size penetration as well as encapsulation of yarn. Different types of water soluble polymers called textile sizing agents/chemicals such as modified starch, polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), acrylates are used to protect the yarn. Also wax is added to reduce the abrasiveness of the warp yarns. The type of yarn material (e.g. cotton, polyester, linen), the thickness of the yarn, type of weaving machinery will determine the sizing recipe. The sizing liquor
