Introduction Fibreglass is also known as glass fibre or fibre glass. The knowledge that fibres could be made from glass is probably as old as glass itself. Molten glass is viscous like treacle, and on being touched with anything, it will ‘string out’ to form a filament when it is drawn away. As glass is […]
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 […]
Definition of Tie-Dye The results of tie dyeing are sometimes similar in appearance to batik, but the designs are made differently. The dye is resisted by knots that are tied in the cloth before it is immersed in the dye bath. The outside of the knotted portion is dyed, but the inside is not penetrated if […]
Denim Yarns Denim yarns now cover a wide range of applications from traditional cotton “Jeans fabric” produced from Ne 5.6/1 to ladies fashion shirts produced from Ne 22/1 and finer. Denim was originally defined as woven, cotton, fabric produced from an indigo dyed warp and a natural-colored filling and most of the yarn counts fell between Ne 5.6 and […]
Introduction Static electricity can cause many processing problems for textile materials, especially those made form hydrophobic synthetic fibres. In most dry textile processes, fibres and fabrics move at high speeds over various surfaces which can generate electrostatic charging from frictional forces. This electrical charge can cause fibres and yarns to repel each other, leading to ballooning. Fabrics and non-woven are also affected […]
Fancy yarn is a yarn that is used to enhance the beauty of apparel. Besides, it has functional properties too. Therefore, it is used in trims, clothing items, carpets, furnishing fabrics, and knitting industries. In this article we will learn about definition, properties and end uses of fancy yarn. Definition of Fancy Yarn “Fancy yarns” […]
Synthetic fibre is a processed fibre where different processing steps are involved. It is not get naturally but through different mechanical processes. It is more durable than any natural fibre. It is also cheap in price. Synthetic fibre bought a revolutionary change in the Textile and Clothing industry. Though it is not easy to dye […]
Introduction The term “scouring” in the generic sense of a process that that removes contaminates from raw wool. Thus, it includes all processes which aim to clean wool including those which use solvent other than water and those which use solid as a carrier for removing the contaminates. Nature of Contaminates The main contaminates of […]
Definition of Functional Finishing The word “textile finishing” defines a series of processing operations applied to grey fabrics to enhance their appearance and hand, properties and possible applications. The term “finishing” includes all the treatments applied to grey fabrics such as scouring, bleaching, dyeing or printing while we will use the term ‘functional finishing’ with reference to all the mechanical or […]
Definition This is a special treatment for cotton yarns, fabrics which improves the fabric luster and wet ability, ensures a covering effect for dead cotton, improves dimensional stability and dyeing efficiency. Mechanism This treatment is done by using caustic soda, which determines the contraction and swelling of the fibres; they become translucent their tensile strength, but reduce their flexural and torsion […]
