Manufacturing Restricted Substances address hazardous substances potentially used and discharged into the environment during manufacturing and related processes, not just those substances that could be present in finished products. Safety requirements and review of risk of different garments have been covered including varieties of accessories. Global and country specific regulations on the restriction of various harmful chemicals used in the manufacturing process of fabrics, apparels and related accessories are also discussed in detail. The book is aimed at textile and apparel industry professionals, retailers, factory heads, buying offices and students intending to join the industry in the areas of quality assurance covering safety and chemical compliance.Woodhead Publishing India in textiles.Clothing and dressSafety measuresTextile fabricsSafety measuresElectronic books.Clothing and dressSafety measures.Textile fabricsSafety measures.646.34Das Subrata1026884WPI India.MiAaPQMiAaPQUtOrBLWBOOK9910148797203321Product safety and restricted substances in apparel2442039UNINA01007nam0 22002651i 450 UON0019880420231205103243.97620030730d1969 |0itac50 baengGB|||| 1||||Matthew Arnolda critic of the Victorian periodCharles H.
