Fibre Technology

Criteria for fibre forming Polymers Development of synthetic ‐ commercial synthetic fibres, Raw materials manufacture. DMT, TPA, MEG, Caprolactum, Adipic acid, Hexamethylene Diamine, Acrylonitrile, Polymerisation ‐ types of polymers ‐ criteria for fibre forming polymers ‐ production of polyethylene terephthalate polymer ‐polyamides ‐ production of Nylon 66 polymer, Nylon 6 polymer.

Fibre Production Methods Production of acrylic fibres ‐ polypropylene ‐ production of other fibres ‐ PVC fibres ‐ PVA fibres Aramid fibres ‐ Melt spinning ‐ Polymer feed ‐ melt spinning equipment ‐ high speed spinning ‐ spin draw processes ‐ crystallization method ‐ melt spinning of PET & PP stable fibres ‐ wet and dry spinning comparison. Spin finishes ‐ functions of spin finish ‐ methods of application of spin finish ‐ spin finish for polyester staple fibres ‐ spin finish for texturing process ‐ effect of spin finish on dyeing.

Fibre Drawing Processes Stretching or drawing ‐ conditions of drawing ‐ machines for draw warping ‐ texturing ‐false twist process ‐ draw texturing‐ staple fibre production, melt spinning ‐ drawing, heat setting ‐ crimping in fibre line ‐ production of melt spin staple fibre ‐ polyester tops for wool blending ‐ Mass coloration and tow dyeing of polyester, nylon, acrylic ‐polypropylene ‐ dyeing in loose fibre and yarn forms of polyester, nylon, acrylic, PP, other synthetic fibres ‐ loose fibre dyeing.

Modified Synthetic Fibres Modified synthetic fibres ‐ modified polyester, Nylon, PP, acrylics ‐ Hydrophilic ‐Hollow –Low pilling ‐ flame retardant‐ bicomponent fibres ‐ Dyeability of synthetic fibres

Testing of Yarn and Fibres Quality control ‐ testing raw material ‐ testing polymers ‐ testing yarns & fibres ‐ waste utilisation of polyester ‐ Nylon 6, 66 ‐ acrylics ‐ PP‐ Energy conservation ‐ pollution control.
