Study Notes
Cotton Count (NeC)
- Cotton Count (NeC) = Number of grains / 7000
- Cotton Count (NeC) = Number of yards x 7000
- Cotton Count (NeC) = Number of grains x 840 / Number of yards
- Cotton Count (NeC) = 8.33 x Number of grains
- Cotton Count (NeC) = 8.33 x Length / Weight
- Where, Length (L) in yards and Weight (W) in grains
Worsted Count (NeW)
- Worsted Count (NeW) = Number of hanks
- Number of hanks = Number of yards / 560
- Worsted Count (NeW) = Number of grains / 7000
- Worsted Count (NeW) = Number of yards x 7000
- Worsted Count (NeW) = Number of grains x 560 / Number of yards
- Worsted Count (NeW) = 12.5 x Number of grains
- Worsted Count (NeW) = 12.5 x Length / Weight
- Where, Length (L) in yards and Weight (W) in grains
Conversion from Direct to Indirect System
- LK = Unit length of known system = 840 yds
- WR = Unit weight of required system = 1000 g
- Nm = Ne x 1.693
- Example: Convert 80 English Count into Metric Count, Nm = 80 x 1.693 = 135.44 Nm
Fabric Classification
Knitted Fabrics
- Fabrics produced by transforming yarn into loops and intermeshing them with adjacent loops
- One set of yarn is used
- Final product: Warper’s beam/ball
Non-Woven Fabrics
- Broadly defined as sheet or web structures bonded together by entangling fibres or filaments mechanically, thermally, or chemically
Bonded Fabrics
- A non-woven fabric in which webs of fibres are held together by a bonding material
Felted Fabrics
- Produced by matting, condensing, and pressing fibres together
Tufted Fabrics
- Made by the combination of:
- Foundation Cloth
- Tufts
Braided Fabrics
- A rope-like fabric made by interweaving three or more yarns in a diagonally overlapping pattern
Laced Fabrics
- An open work fabric made from intermeshing threads into a fabric
Comparison between Different Fabrics
Woven Fabrics
- Produced by the interlacement of two sets of yarns
- Sizing is required before weaving
- Yarn preparation is must
- Production capacity is less than that of knitted fabrics
- Production cost is higher
- About 48% of fabrics are produced by weaving techniques
- Elastic property is less than knitted fabrics
- Dimensional stability is higher than knitted fabrics
Warping Process
- Collects large number of required yarns from the winding package onto the beam
- Different nature or different colours of yarns can be collected on the beam according to the required arrangement
- Winding of a specific type of package as required by the subsequent process
Types of Warping Process or Warping Machines
- High-speed (direct) warping
- Sectional (indirect) warping
- Ball (for denim) warping
- Draw (heat set) warping
