YARN AND YARN MANUFACTURING-Blow room Section-4.4.1

 Blow room Section :

Basic operation in the Blow-room: 
  • Opening the cotton bale 
  • Homogeneously mixed or blended tufts 
  • Clean fibre tufts 
  • Convert fibre tufts into a fibrous sheet, is called lap. 
Objects of Blow-room: The basic purpose of blow-room line is to supply following qualities of fibre tufts to the carding process.
  • Small fibre tufts 
  • Homogeneously mixed or blended tufts
  • Clean fibre tufts 
  • Convert fibre tufts into a fibrous sheet, is called lap.
Blending: The method of mixing different fibres within a specific ratio is known as blending.
Mixing: The method of combining identical fibres in various grade of different ratio is known as
mixing. 

Conventional Blowroom line:  There are different types of conventional blow-room line. It differs manufacturer to manufacturer. For example a typical blow-room line as follows:
  1. Hopper bale opener 
  2. Ultra cleaner or step cleaner 
  3. Vertical or twine opener or cleaner 
  4. Hopperfeeder-1 
  5. Porcupine opener 
  6. Hopperfeeder-2 
  7. Scutcher.

YARN AND YARN MANUFACTURING-Types of Fibres-4.1.1

YARN MANUFACTURING An assemblage of fibres that is twisted or laid together so as to form a continuous strand that can be made into a textile fabric. So a yarn is a strand of natural or man-made fibres or filaments that have been twisted or grouped together for use in weaving, knitting, or other methods of constructing textile fabrics. The type of yarn to be manufactured will depend on the fibres selected; the texture, or hand, of the fabric to be made; and qualities such as warmth, resiliency, softness, and durability required in the fabric's end uses. Types of Fibres: All the textile fibres are classified according to their staple length into two categories, such as staple fibre and filament. Staple fibres:   It has a limited length that varies according to the type, such as cotton, wool, jute etc.There are two types of staple fibre, one is short staple fibre another one is long staple fibre. Cotton is mainly short staple fibre and other maximum natural fibres a

YARN AND YARN MANUFACTURING-Doubling and Drawing-4.7.1

Image
DOUBLING AND DRAWING Doubling and Drawing  :   In preparing the fiber tufts for spinning, doubling and drawing represent two essential operations and their combined effect permits a sliver with a more regular section to be obtained(through doubling) equipped with parallel fibers (through drawing) as well as the count requested by the spinning plan.   The drawing operation done with the machine called the draw frame, permits a homogeneous blend both with fibers of the same nature as well as fibers with a different nature; the doubling steps are usually between four and eight. On a par with fiber characteristics such as length and fineness, a sliver with parallel fibers permits a yarn with better regularity and resistance. The drawing depends on some factors such as the number of doubling carried out and the value of the count of the entry sliver and delivery sliver. With drawing, curls, crimps and hooks are also eliminated, meaning the fibers folded in on themselves,
