The document outlines the processes involved in weaving, including warping, sizing, drawing-in, looming, folding, and dispatching fabric. Each process includes definitions, calculations, management strategies, working principles, and budget considerations, emphasizing the importance of efficiency and quality control. Key aspects such as yarn alignment, protective sizing application, loom setup, and careful dispatching practices are crucial for successful fabric production.

2. • Warping is the process of arranging
yarns in parallel fashion to form the
warp beam, which is used in the
weaving process. The main objective
of warping is to convert yarns from
individual packages into a single
sheet of yarns arranged in parallel
and uniformly tensioned.
• Types of Warping
• Direct Warping:
• Also known as beam warping or
direct beaming.
• Involves winding yarns directly
from individual packages onto a
warp beam.
• Sectional Warping:
• Also known as pattern warping.
• Involves winding yarns in
sections on a warping drum and
then transferring them onto a
warp beam.

3. • Calculations in Warping
• Yarn Count Calculation:
• The total length and weight of yarn
needed can be calculated based on the
yarn count and the warp density.
• Warp Density:
• The number of ends per unit width
(usually per inch or centimeter).
• Warp Length Calculation:
• Total Warp Length = (Fabric Length +
Loom Waste) * Number of Ends
• Beam Calculations:
• Determining the diameter and weight of
the warp beam based on the yarn count,
warp length, and density.

machines (direct or
sectional warping
machines).

equipment (tension
devices, creels,
etc.).
Operational Costs:
•Cost of yarn.
•Labor costs.
•Maintenance and
repair costs of
warping machinery.
Efficiency and
Waste Management:
•Efficient use of
yarn to minimize
waste.
•Regular
maintenance to
prevent machine
downtime and
repair cost

6. • . Sizing
• Definition: Sizing is the process of applying a protective adhesive
coating to the warp yarns to strengthen them and reduce breakages
during weaving.
• Calculations
• Size Pick-Up Percentage: (Weight of sized yarn - Weight of unsized
yarn) / Weight of unsized yarn * 100
• Size Recipe: Amount of sizing agents needed based on yarn type and

7. • Management
• Recipe Management: Formulate and maintain
recipes for different yarn types.
• Process Monitoring: Ensure consistent
application of size to maintain yarn quality.
• Quality Control: Regularly check the
strength and flexibility of sized yarn.
• Working Principle
• Preparation: Mix sizing agents (starches,
resins, etc.) with water to create a size
bath.
• Application: Pass the warp yarns through the
size bath and then through drying cylinders to
remove excess moisture.
• Drying: Dry the yarns uniformly to ensure
even application of size.
• Budget
• Initial Investment: Sizing machine, drying
cylinders, and mixing equipment.
• Operational Costs: Sizing agents, water,
energy for drying, labor costs.
• Maintenance: Regular cleaning and
maintenance of sizing equipment to prevent
clogging and ensure efficiency.

8. • 2. Drawing-In
• Definition: Drawing-in
is the process of
threading warp yarns
through the various
parts of the loom
(heddles, reed, etc.) to
prepare for weaving.
• Calculations
• Ends per Dent: Number
of warp yarns per dent
in the reed.
• Total Ends: Number of
warp ends needed for the
width of the fabric.
• Drawing-In Time: Time
required to draw in a
specific number of warp
ends.
• .

9. • Management
• Plan: Develop a drawing-in
plan based on the fabric design.
• Training: Ensure workers are
skilled in the drawing-in
process to minimize errors.
• Inspection: Regularly inspect
the threading to prevent weaving
defects.
• Working Principle
• Preparation: Set up the loom
with the appropriate heddles and
reed.
• Threading: Pass each warp yarn
through the heddles and the reed
according to the drawing-in
plan.
• Verification: Check for
correct threading to ensure the
pattern and structure of the
fabric.
• Budget
• Initial Investment: Drawing-in
frame or machine.

10. • . Looming
• Definition: Looming is the process of
setting up the warp beam on the loom
and getting it ready for weaving.
• Calculations
• Warp Beam Tension: Calculate the
tension required based on yarn type
and fabric specifications.
• Loom Efficiency: Measure the weaving
efficiency based on the loom's speed
and downtime.

11. • Management
• Setup: Efficiently set up the
warp beam and other loom
components to minimize downtime.
• Monitoring: Continuously monitor
the loom during operation to
detect and fix issues promptly.
• Maintenance: Regular maintenance
of the loom to ensure smooth
operation.
• Working Principle
• Mounting: Mount the warp beam
onto the loom.
• Tensioning: Apply the correct
tension to the warp yarns.
• Weaving Setup: Adjust the loom
settings (e.g., shuttle, heddles)
according to the fabric design.
• Budget
• Initial Investment: Purchase of
looms and auxiliary equipment.
• Operational Costs: Labor,
energy, and consumables (e.g.,
shuttle).
• Maintenance: Routine maintenance
and repairs of looms.

12. • . Folding
• Definition: Folding is the process
of folding the finished fabric in
preparation for storage or shipping.
• Calculations
• Fold Length: Determine the length of
each fold based on fabric width and
storage requirements.
• Fold Count: Calculate the number of
folds needed for a specific fabric
length.

13. • Management
• Efficiency: Streamline the folding
process to minimize handling time.
• Quality Control: Ensure uniform
folding to prevent creases and damage to

folded manually or using automated
folding machines.
• Precision: Ensure precision in folding
to maintain fabric quality and
presentation.
• Budget
• Initial Investment: Folding tables or
folding machines.
• Operational Costs: Labor costs for
manual folding or maintenance for
automated machines.

materials (e.g., boxes, pallets).

14. • 5. Dispatch

schedule dispatches accordingly.
• Logistics Coordination:
Coordinate with logistics
providers to ensure timely and
cost-effective delivery.
