TX4009 Structural Mechanics of Fabrics Syllabus:
TX4009 Structural Mechanics of Fabrics Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE
To enable the students to learn about geometry of fabric, mechanics of fabric deformation fabrics
UNIT I GEOMETRY OF CLOTH STRUCTURE
Geometry of plain and non-plain weaves; Peirce and Olofsson models; crimp ratio and thread spacing; jamming of threads; crimp interchange, balance of crimp.
UNIT II FABRIC DEFORMATION
Fabric deformation under tensile stress; prediction of modulus; tensile properties in bias direction
UNIT III OTHER FABRIC DEFORMATION
Compression, shear, bending and buckling; fabric handle; spirality and skewness formation and control
UNIT IV KNITTED FABRIC STRUCTURES
Geometry of weft and warp knitted structures, influence of friction on knit geometry; load extension of warp knit fabrics; biaxial stress behavior of plain-knit fabrics
UNIT V NONWOVEN STRUCTURES
Structure of felts; mechanical behavior of needle felts; structure of stitch bonded fabrics, chemical and thermal bonded fabrics
TOTAL: 45 PERIODS
OUTCOMES:

CO1: Understand the geometry of woven cloth
CO2: Know fabric deformation under tensile stress
CO3: Understand the mechanics of other fabric deformations
CO4: Know the mechanics of knitted fabric structure
CO5: Understand the structure of nonwovens
