00 The process of making yarns from fibers is called Spinning. There are several methods of Spinning : Such as For Staple Yarn. Ring Spinning Open end / Rotor Spinning Friction Spinning. Self twist Spinning Electrostatic Spinning Vortex Spinning Air-Jet Spinning Twist-less Spinning. For Filament Yarn. Wet Spinning Dry Spinning Melt Spinning Bi-Component Spinning …

00The vat dyes are found amongst oldest natural coloring matters used for textiles. The name ‘Vat dyes’ derived from the large wooden vessel from which vat dyes were first applied. Vat dyes provide textile materials with the best color fastness of all the dyes in common use. The fiber most rapidly colored with vat dyes …
Continue reading Vat Dye And Its Properties00Classification of direct Dye with the basis of Applications 1.Class A ( Self Leveling ): Dye which migrate well and therefore have high leveling power. 2.Class B ( Salt controllable ): Dyes of poor leveling power where exhaustion must be brought by the controlled salt addition. 3.Class C ( Temperature Controlled ): Dyes which are …
Continue reading Classification of direct Dye with the basis of Applications00Direct Dye: The dye which have strong affinity towards the fiber which can be applied directly on the fabric and which do not need any assistance, such type of dye is called direct dye.This dye posses a great affinity towards the cellulosic fibers. Any fiber except synthetic fiber and tri-acetate fiber can be dyed by …
Continue reading Direct Dye properties and chemical Classification00Acrylic fibers made from 100% acrylonitrile (CH2=CHCN).So acrylic fibers are difficult to dye for their compact structure. To overcome this and to improve solubility in solvent so that the polymer may be wet or dry spinning, co-polymers are now used. Then the acrylonitrile is copolymerized Now the polymerization of acrylonitrile X, Its co-polymer is carried …

Capable of being assembled interlaced or interlocked into some intermediate production such as ropes, cords, woven fabric, knitted fabric. Types of Yarn produced in spinning: 1.Carded yarn; For woven For knitted 2.Combed yarn; For woven For knitted 3.Rotor yarn. 4.Compact

There are several methods of Spinning: Such as For Staple Yarns 1)Ring Spinning. 2)Open-end/Rotor Spinning. 3)Friction Spinning. 4)Self-twist Spinning. 5)Electrostatic Spinning. 6)Vortex Spinning. 7)Air-jet Spinning. 8)Twist less Spinning. For Filament Yarns 1)Wet Spinning. 2)Dry Spinning. 3)Melt Spinning. 4)Bi-component spinning. 5)Film Splitting. For Integrated Multi-component Yarns …
Continue reading Different Type of Fibre Spinning Method00Basic dyes also called cationic dyes, because in solution basic dye molecule ionizes. Causing it’s colored component to become a cation or positively changed radical. In market basic dyes are obtained as a basic salt usually chlorides, but sometimes oxalates or double salts with zinc chloride (ZnCl2). Basic dye specially used for jute fibre, also …
Continue reading Types and properties of Basic Dye00Cotton Fibre widely used natural firbe which is constist of 85.5% cellulose. That’s why It’s also called cellulosic firbe. Cotton is the most important natural fibre and it accounts for about 50% of the total fibre production of the world. Cotton fibre is obtained from the seed of the botanical family Gossypium. It is a cellulosic …
Continue reading Cotton Fibre – It’s properties, Composition & Uses00Man Made Fibre Spinning: The conversion of polymer into fibre is called spinning. The fibre forming substance is made temporal fluid extruded through spinneret & then return to solid state (by solidification) in fibre form. Types of spinning: 1.Melt spinning. 2.Dry spinning. 3.Wet spinning. Spinneret: A nozzle or plate provided with fine holes or slits …
