Geometrical prints are basically the prints which are made/developed from
geometrical shapes like circle , rectangle, straight lines etc. as below

have a horizontal as well as veritcal axis as

4. WHY DOES BOWING HAPPEN?
• In Textile mills, maximums motions are negative motions i.e. the front rolls
drives the fabric & due to tension created by the fabric movement, back roll
moves. In this condition the central part of fabric runs in tension while the
side selvedge area become loose causing displacement
• Displacement is higher in case of lighter weight fabric like voiles , chiffons ,
gauzes etc where as in case of heavy fabrics like poplin/canvas, displacement
is very minimal.
• The yarn displacement becomes the prime reason for bowing in fabrics.
• As a standard rule, for a medium weight fabric like cambric, the skewing
%age is 3-5% where as in case of light weight chiffons & voiles the bowing
goes up to 8-10%also.

5. BOWING IN GEOMETRICAL PRINTS
• In geometrical prints, 2grains lines are visible, horizontal & vertical.
• Hence in case of geometrical prints, even a slightest yarn displacement
will be visible in form of bowing/skewing.
• As a normal case, same bowing level of geometrical prints will have a
higher visibility than floral / abstract prints

6. PRECATIONS TO BE TAKEN TO
CONTROL BOWING
• Light weight qualities should be run on such machinery which exerts
lesser tension. Like in case of voile, mill prefers winch or soft flow
machine instead of CDR or jiggers
• The fabric rolls should be stitched correctly to avoid bowing at stitching
areas
• Bowing controller to be installed at stenter are to minimize bowing.
