Processing of Man-made Fibres and Blends on Rotor Spinning

Since rotor spinning established its superiority over conventional spinning, blended and manufactured yarns have attracted spinners. One of the essential requirements of blended yarn is the degree of homogeneity in blending their components throughout the length of yarns spun and the uniform distribution of the individual fibre component in the cross-section. In this spinning, the […]

Polyester Fibre Production Process and End Uses

Introduction Polyester are polymers made by a condensation reaction taking place between small molecules, in which the linkage of the molecules occurs through the formation of ester groups. Polyesters are commonly made by interaction of a dibasic acid with a dihydric alcohol: HOOC-X-COOH + HO-Y-OH → …OC-X-COO-Y-OCO-X-COO-Y-OCO… The formation of polyester was studied by Wallace H. Carothers […]

Mixing, Blending and Bale Management

Mixing Mixing could be thought of combining of fibres together in somewhat haphazard proportion whose physical properties are partially known so that, the resultant mixture has only generally known average physical properties which are not easily reproducible. Blending Blending is based on the measurement of important fibre properties i.e, length, strength, cleanliness, e.t.c. Quantitatively proportioning […]
