      Stitch Formation and its Uses 

 

Stitch Type
No.
Formation
Characteristics
Application
Single thread chain stitches
101
One needle thread intralooping with itself
elastic, easy to unravel
basting, buton sewing, label setting, back closing , tacking
103
use a curve needle to penetrate the fabric surface but stitich does not show on the face
invisible on garment surface
hemming of pants and skirts
Hand stitches
200
Done by hand with one needle thread
Flexible use
Basting on tailored jackets
Lock Stitches
301
interlacing of needle thread and bobbin thread
reversible, strong, versatile, secure,neat flat but not stretchable
top stitching, common seam sewing
304
similar to 301 but in a zigzag pattern
similar to 301 but stretchable
attaching elastic/lace to lingerie decoration
Multithread chain stitches
401
one needle thread and one looper thread, interlooped and interlaced together
continuous running, strong, duarable, extensible, thick and can be unravelled
waist bands, inseam of jeans, side seam/sleeve seam of shirts, rainwear
402
a looper thread travels betwen two needle threads on the underside of the fabric and form a ridge
for stimulative effect
stimulate permanant crease on the knitted pants and cording backs of gloves
402
similar to 401 but zigzag pattern
higher elasticity than 401
attach waist band lining to men's trousers
406
similar to 402 but does not ridge up
concealed raw edges on the underside to produce a flat and comfortable seam
cover seaming, sewing belt loops,binding and attaching elastic to underwear,hemming t-shirts and sportswear
407
similar to 406 but with 3 needle threads and one looper thread
high elasticity , stronger and better coverage effects
attaching elastics to briefs, panties and undergarments
Overedge Stitch
501
one needle thread interlooping itself warps and protects the edge
ealstic , allow the seam to break open, easily unravelled
break open seaming
502
formed by 1 needle thread and 1 looper thread
Stronger than 501
bag seaming
503
similar to 502 but the needle thread interlocks with the looper threads on the edge of the plies
better edge coverage than 501 and 502, highly elastic
thin surging on thread,blind hemming on T-shirts
504
one needle and 2 looper threads interlock on the edge of the plies
higher extensible, tighter structure, prevent fraying but bulky and easily runback
popular serging and seaming of knit garments
514
formed by 2 needle thread and 2 looper threads
produce a wider bright than 504, strnger and more elastic
strong seaming of knits and woven fabrics
Cover stitch
602
similar to 406 but it has a covering thread on the top surface
provide excellent top and bottom cover and flat seam
attaching knit collar on kint garments
605
similar to 407 but it has a covering thread on the top surface
better coverage than 602
cut edge bining , elastic attaching
