It is the most versatile and widely accepted spinning technology due to high degree of fibre control it provides during drafting and a wide range of yarn count that it can produce.
How are fancy yarns made?
Typical fancy yarns include snarl, spiral, loop, chenille, slub and nep. … Manufacture of fancy yarns often involves plying and cabling together different yarns of varying counts and twists. The density (tpi) and direction of twist (S/Z) are often manipulated during plying and cabling so as to create particular effects.
How many types of fancy yarn are there?
Various names are used to describe the different yarn effect, these can be classified in to Eight basic profiles. The basic profiles of the fancy yarns are Spiral, Gimp, Slub, Knob, Loop, Cover, Chenille and Snarl yarns.
What is used for spinning yarn?
A spindle is a straight spike usually made from wood used for spinning, twisting fibers such as wool, flax, hemp, cotton into yarn.
What is Siro spinning?
SIRO SPUN™ – SPINNING PROCESS
The technology maintains two separate strands during the spinning process, and this allows a number of fibre-binding mechanisms to operate before the strands are twisted about each other.
What is the basic structure of a fancy doubled yarn?
The basic structure of a fancy doubled yarn consists of ‘core’ threads, an ‘effect material’, and a ‘binder’ which, as the name suggests, ensures that the entire structure holds together.
What is textured yarn?
1. Textured Yarns: ‘Textured’ is a general term for any continuous filament yarn whose smooth straight fibers have been displaced from their closely packed, parallel position by the introduction of some form of crimp, curl, loop or coil.
What is fancy weaving?
Fancy weaves—such as pile, Jacquard, dobby, and leno—require more complicated looms or special loom attachments for their construction. Three types of weaves: plain, twill, and satin. Encyclopædia Britannica, Inc. The manner in which the yarns are interlaced determines the type of weave.
What is yarn numbering system?
In a direct yarn counting system, the yarn number or count is the weight of a unit length of yarn. This means the higher the yarn count number, the heavier or thicker the yarn. It is fixed length system. This system is generally used for jute or silk yarn. … e.g. 30 Tex indicates that 1000 meters of yarn weight 30 grams.
What is spiral yarn?
A spiral or corkscrew yarn is a plied yarn that displays a characteristic smooth spiraling of one component around other.
Which machine is used for spinning?
The spinning jenny is a multi-spool spinning wheel. It was invented circa 1764, its invention attributed to James Hargreaves in Stanhill, near Blackburn, Lancashire. The spinning jenny was essentially an adaptation of the spinning wheel.
What are the types of spinning?
What Is Spinning? | Types Of Spinning Process
- Ring Spinning.
- Rotor Spinning.
- Friction Spinning.
- Self Twist Spinning.
- Electro-Static Spinning.

What is spinning name two devices used for spinning?
The two hand-operated devices used for spinning are Takli and Charkha.
What is Vortex spinning?
“VORTEX® spinning” is a technology which uses an air vortex to spin out the yarn. Fibers formed by these air flows possess a unique structure, and this provides the yarn with a wide range of functionalities.
What is Airjet spinning?
Air-jet spinning is also known as Vortex or fasciated yarn spinning. It was introduced in the 1980s. … Twist is inserted to the fibres, mostly on the yarn surface, by the vortex created in one or two air-jet nozzles. The resulting yarn consists of a core of parallel fibres and a sheath of wrapped (twisted) fibres.
What is compact spinning?
Compact spinning is a novel concept generated through re-engineering of established ring spinning process by attaching a pneumatic zone to existing ring spinning machine. Compact spinning achieves a remarkable improvement in yarn quality and yarn structure through better utilization of fibre properties.
