This document summarizes common defects that can occur during the weaving process and their causes and remedies. It identifies defects such as double ends, wrong end color, slubs, broken ends, double picks, balls, holes, oil spots, reed marks, foreign materials, and thick and thin places. Each defect is explained along with how it can occur and recommendations for preventing or fixing the issue, such as ensuring proper sizing, drawing, spinning, tension control and cleaning of yarns. The goal is to identify defects early to maintain fabric quality and the aesthetic appeal of final garments.

2. Common faults of weaving
 Defects found in fabric ruin the aesthetic appeal and quality of the final garment,
making it really important to identify and take corrective measures at the right time.
 Defects in woven fabric can be a result of
 Yarn imperfections
 Incorrect weaving process
 Errors in the finishing process.

3. Common Faults
 Double end
 Wrong end color
 Slub or slug
 Broken end
 Double pick
 Balls
 Holes
 Oil spot
 Reed mark
 Foreign material
 High twist yarn
 Thick and thin places

4.  DOUBLE END
 REASON
 This kind of fault is produced in woven fabric when the
two ends of warp sticks get together after sizing.
 REMEDIE
 Proper sizing.

5.  WRONG END COLOR
 REASON
 It happens due to wrong drawing of
colored yarn.
 REMEDIE
 Proper drawing

6. SLUB
 It is caused by an extra piece of yarn that is woven into fabric.
 It can also be caused by thick places in the yarn.
 REDMIDIE
 Ensure proper spinning and yarn cleaning during winding.

7. Broken ends
 Space created in the fabric when a yarn partially or completely is missing
from the fabric
 Caused by improper working of warp stop motion
 Remedies
 Check warp stop motion assembly before weaving starts

8.  DOUBLE PICK
 REASON
 This defect happens when more than one pick is
inserted in the single shed.

 REMEDIE
 Proper pirn changing with weft feeder
mechanism.

9.  BALLS
 REASON
 If the warp is hairy or thick then reed will beat it
then creates the ball.
 REMEDIE
 Change the reed or reduce the tension of warp
ends .

10.  HOLES
 REASON
 Hairy yarns.
 REMEDIE
 If we control the balls the holes will control
automatically .

11.  OILL SPOT
 RAESON
 Too much oiling on loom shed.
 REMEDIE
 Can be removed by dry cleaning.
 It is remove in the scouring process .

12.  REED MARK
 REASON
 Caused by high warp tension.
 REMEDIE
 Ensure warp tension as required
 Early shed timing.

13.  FOREIGN MATERIAL
 REASON
 If the yarn contain foreign material like plastic
,seed etc.
 REMEDY:
• to check the yarn in during spinning

14. HIGH TWIST OF YARN
 REASON
 High TPI of yarn.
 REMEDIE
 To buy a suitable tpi yarn.

15. Thick and Thin places
 Reason .
 Count variation
 Remedies.
 To ensure constant count during the process.
