TY4005 Bio Processing of Textiles Syllabus:

TY4005 Bio Processing of Textiles Syllabus – Anna University PG Syllabus Regulation 2021

OBJECTIVES

To enable the students to know about the
 Pollution and its control in textile processing industries
 Application of bio technology in textile wet processing

UNIT I INDUSTRIAL BIO-TECHNOLOGY

Industrial microbial products–applications, primary metabolites and secondary metabolites, Enzymes & Proteins– sources and applications, cell and enzyme immobilization, Industrial plant products– production of enzymes and poly sacchrides.

UNIT II ENVIRONMENTAL BIO-TECHNOLOGY

Detailed study about pollution and its control in textile processing industries. Waste watert reatment systems– Anaerobic & Aerobic systems, Bio-degradation– Micro organism in pollution control; Biomass production; waste as renewable sources of energy– Production of biogas production of hydrocarbon– Hydrogen fuel.

UNIT III ENZYMES USED IN TEXTILE INDUSTRY

Enzymes for desizing, scouring & bleaching Enzyme activity – initiation, propagation and termination reactions – reaction conditions – properties of substrates and results of enzyme treatment. Enzyme activity of amylo glucosidase, pectinase, glucose oxiclase, peroxidases and other enzymes used for bleaching decolourisation of textiles using laccases. BioPolishing enzymes such as cellulases. Bio- washing enzymes using cellulase proteases for scouring of animal fibres, degumming of silk and modification of wool properties.

UNIT IV EVALUATION OF ENZYME TREATED FABRICS

Weight loss, Whiteness index, Absorbency, Tensile strength, Handle of fabric and Abrasion resistance. SEM analysis and other structure related studies.

UNITV BIO–PROCESSING IN TEXTILES

Bio-bleaching, combined bio – processing, bio washing, bio polishing, Denim fading, antiodour and antimicrobial finishes, biofinishing and other applications.

TOTAL: 45 PERIODS

OUTCOMES

Upon completion of this course the student shall have knowledge on
 The origin and concept about enzymes.
 Waste water treatments associated with enzyme in textile wet processing industry.
 The contribution of enzyme in pretreatment processes.
 Analysis of fabric properties of enzyme treated fabrics.
 The bio processing in textile industry.
