GAS singeing and their causes:- • • • • • • • Incomplete Singeing Uneven Singeing Across the Fabric Width • • • • • Both side of fabric is singed in gas singeing m/c Uniform temp can be controlled Uneven Singeing Along the Fabric Length Horizontal Singeing Stripes Vertical Singeing Stripes Over-singing or Thermal Damage of the Fabric Formation of Small Beads of Molten Material Advantages of gas singeing: -... effect Indirect Singeing Includes: • Infra-red ray burning system( both for woven & knit fabric) 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering Why Knit Singeing Is Done? In case of knitting process normally singing is not done Because the purpose of singing like removing of having fibres from the fabric surfaces is done in here by using enzyme But simply... good GAS singeing • • • • Following are three essential conditions for good singeing: A flame with high mechanical & thermal energy to quickly burn thermoplastic protruding fibres (e.g polyester) without any molten beads formation A homogeneous flame with uniform mechanical & thermal energy to result in uniform singeing An optimal flame/fabric contact time to neither result in incomplete not over -singeing. .. protruding fibers are removed in singeing which could cause diffused reflection of light 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering Singeing System: There are two types of singeing system are found 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering Direct Singeing System: The action of burning away... singing is done An enzymebased process was applied in finishing viscose fabrics, which are very susceptible to pilling because of individual loose fibres ends which protrude from surface, and impurities and fuzzes 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering • Knit singing machine: Normally the machine which is used to removing the hairy fibres of the... Technically, singeing refers to the burning-off of: • • Loose fibres not firmly bound into the yarn and/or fabric structure; Loose yarns not firmly bound into the fabric structure; 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering • • • • • Singeing Objectives & advantages:... of Textile Engineering What is singeing ? 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering Singeing is designed to burn off the surface fibres from the fabric to produce smoothness The fabric passes over brushes to raise the fibres, then passes over a plate... In gas singeing, brush is used which stands the lying projecting the fibers Plates not decay on gas singeing machine The fabric in interstices of warp and weft can be singed 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering What is an Enzyme? 7/30/15 SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering • • Enzymes... amino-acids, which are produced by living organisms Each enzyme is a made of a sequence of amino acids (like pearl on a string, picture 1) folded into a unique three-dimensional structure that determines the function of the enzyme Only a small part of the enzyme participates in the catalysis of biochemical reactions: the active site (picture 2) Enzymes are therefore very specific (e.g cellulose can only .
