Carbon fibre: Properties and End Uses

Introduction In 1963 a team of British scientists, W. Watt, W. Johnson, and L.N. Phillips, working at the Royal Aircraft Establishment, Farnborough, U.K., developed techniques for producing carbon fibres of high strength and outstanding rigidity. These fibres were in commercial production by 1968 and have since become of great importance, especially in the field of[…]

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[…]

A Guide to Filament, Bulletproof and Ballistic Yarns

The first filament yarn was introduced through natural silk yarn derived from nature. And with the advancement of science gradually yarns like Bulletproof and Ballistic were introduced. In this article, we will know about Filament, Bulletproof and Ballistic Yarns.   Definition of Filament Yarn Man first learned the silk worm’s filament yarn technique, which extrudes fibroin – a viscous[…]

An Overview of Water Jet Loom

Water Jet Loom An effort to achieve:    Weaving machine makers produced gripper shuttle and rapier machines belonging to second generation of shuttle loom. But in both machines, something solid enters shed and yarn is suddenly accelerated to very high velocity-stretching tender yarns undesirably. Then third generation of Air Jet and Water Jet looms when fibre spun as well[…]

What is Twist in Yarn: Definition and Meaning

Definition of Twist The process by which fibres are arranged around the axis of yarn is called yarn twist. It imparts strength to the yarn. Higher the twist more the yarn strength, till optimum twist is reached. But due to property of ‘fabric assistance’ even less than optimum twist will produce fabrics of maximum strength. It also[…]

What is Fashion, Fashion Trend and Style

Definition of Fashion We may define fashion in many ways. The definitions of fashion are mentioned as follows:  Definition of Fashion Trend Fashions move in a direction e.g. skirt lengths may move from calf length to knee from one season to the next or, short jackets may gradually be gaining more acceptance than hip length[…]
