coverings Consumer Product Safety Commission CPSC CPSC is charged with protecting the public from unreasonable risks of injury or death associated with the use of the thousands of types of consumer products under the agency s jurisdiction CPSC is committed to protecting consumers and families from products that pose a re electrical chemical or mechanical hazard CPSC s work to ensure the safety of consumer products such as toys cribs power tools cigarette lighters and household chemicals National Fire Protection Association NFPA reduce the worldwide burden of re and other hazards on the quality of life by providing and advocating consensus codes and standards research training and education The world s leading advocate of re prevention and an authoritative source on public safety NFPA develops publishes and disseminates more than 300 consensus codes and standards intended to minimize the possibility and effects of re and other risks American Apparel and Footwear Association AAFA the national trade association representing apparel footwear and other sewn products companies and their suppliers which compete in the global market The trusted public policy and political voice of the apparel and footwear industry its management and shareholders its four million U S workers and its contribution of 350 billion in annual U S retail sales Oeko Tex Oeko Tex Standard 100 or ko Tex Standard 100 is an international testing and certi cation system for textiles limiting the use of certain chemicals It was developed in 1992 Being certi ed by Oeko Tex indicates the business is not using any of the Restricted Substances in its products American Association of Textile Chemists and Colorists AATCC The Association continues to evolve to meet the needs of those in the ever changing textile and materials industries AATCC is internationally recognized for its standard methods of testing bers and fabrics to measure and evaluate such performance characteristics as colorfastness appearance soil release dimensional change and water resistance ASTM Flame Resistance the property of a material whereby aming combustion is prevented terminated or inhibited following application of a source of ignition Chapter 24 What is the difference between aesthetic and functional nishes A aesthetic affects the appearance or hand of the textile functional affects the performance of the textile often not visible may be topical only on the surface or absorbed into the ber affects performance of textile some are applied at ber or yarn level effect the end product but may be put on at different stage ex wrinkle resistance re resistance waterproo ng antimicrobial nishes anti static How are nishes classi ed based on how long they remain in or on the fabric A permanent nishes last the lifetime of the product usually permanently set in the product often utilize characteristics of synthetic fabrics heat sensitive bers subjected to nishes involving heat treatment many are in solution don t wear off durable nishes usually have a certain lifespan involves resin chemical or mechanical treatments chemical you can t see mechanical you can see may or may not say how long life span is temporary nishes removed after one or two launderings or dry cleanings starch nish many are part of manufacturing process What types of bers can be heat set permanently A synthetic bers heat sensitive bers subjected to nishes involving heat treatment in solution How can a durable nish be applied to a natural ber A chemical resin or mechanical treatment Are there any types of nishes that can be applied at home by the consumer A Chemicals that affect fabric hand hand builders Soil and stain repellency Scothcgard Zepel What is a calendar A friction calendar An embossing calendar A calendar mechanical nish pass fabrics between a series of two or more rollers purpose smooth fabric or create interesting surface effects may or may not be permanent very high pressure so the rollers press the fabrics sometimes has a design on it sometimes atten them sometimes add chemicals sometimes add heat embossing calendar pressing a pattern onto fabrics permanent when applied to thermoplastic bers durable when applied to fabrics with resin treatment temporary on other fabrics has a certain lifespan durable How is fabric polished glazed or cired A glazed fabric saturated with starch or resin dried slightly fed into machine with rapidly moving heated roller polishes fabric usually put into calendaring rolls something added to it to polish not just the machine ex chintz or polished cotton cired high surface polishing the wet look natural bers waxes or resins fabrics made with thermoplastic bers fuse slightly under the heat of rollers very shiny when goes through rollers they are heated thermoplastic bers soften when they cool they stay permanently in that con guration heat setting What is moir A watered or clouded appearance ribbed fabrics taffeta
