How it’s Made: T-Shirts, Polo Shirts, Sweatshirts, Hoodies
Everyone loves to wear a T-shirt. People of all walks of life; celebrities
or even heads of states; all loves to wear a T-shirt, at some moment of
their life; almost everyday!
People often think that T-shirt is like any other garment; like our
normal shirts & jackets. No, it is not! They are very different.
Technically woven garments and Knitted T-shirts are as different as a
Cow and a Goat. The normal shirts & trousers we wear are woven,
but T-shirt material is knitted. The yarn used for shirts are woven
using weft & warp yarns, where as the yarn used for knitting T-shirts
is ring spun hosiery; a different structure from the very beginning.
The amoebic nature of the knitted T-shirt fabric makes it all the more
difficult in manufacturing.
Two types of
hosiery yarns are
carded. This just
and un-cleaned. Combed yarn is much more expensive and will result
in premium quality T-shirt.
Premium quality T-shirt sellers make it a point
to mention that their T-shirts are made of
combed yarn. Most of these premium brands
outsource their products from large factories in
India or Bangladesh.
There are two types of knitting machines.
Circular knitting and open width / flat
knitting. The flat knitting is generally used for
knitting woolen sweaters. T-shirt fabric is mostly knitted on Circular
knitting machine. This is what makes it possible to have tubular T-
shirts or without side seams. Tubular T-shirts or Polo shirts are no
longer preferred, since it could lose shape after wash, unless knitted
in the right gauge & weight, using good quality yarn. Maintaining the
exact measurements also is an issue, of T-shirts with seamless sides.
The stretchy nature of knitted fabric gives nice fit, breathing comfort
and warmth to your body.
Knitting Rib trims for the neck and cuffs is very similar machine, but
with different head. Similarly for knitting pique for making Polo
Shirts or Sweatshirt Hoodies or Interlock material, are very similar
machines. All these machines look alike very much, but with different
heads to churn out fabric in different patterns.
Collar Knitting Machines are Flat Knitting
Knit fabric is thoroughly checked for defects
and then sent for dyeing for color, or
bleaching for white. Before dyeing color,
the fabric is half bleached by good dyeing
companies, which though expensive,
will result in fabric with extra bright rich
color & feel, and even depth. The new dyeing
method using state of the art SOFT FLOW
machines and AZO FREE reactive dyes, make
T-shirts or Polo shirts look casually formal.
After dyeing or bleaching,
when the fabric is dried, It
undergoes a process called
compacting. Under normal
conditions, this is done at 95
C dry state in new advanced
machines. This process not
only controls shrinkage, but also gives dimensional stability to the
knit fabric. It also decreases the abrasion resistance of the fabric with
less tendency to pilling.
When the fabric is ready every lot is sent to lab,
where it undergoes several stringent tests for
color fastness, shrinkage and other wash tests,
under different modalities. After certified OK,
the cut order is given and from now it gets more
interesting and challenging at the manufacturing
Fabric is cut by machine and there are very advanced CAD assisted
laser-cutting machines available now. Smaller quantities are cut by
standard Lay cutting machine.

Overlock machine, flat lock machine and Single needle machine,

Overlock stitching, using an over lock
Machines is for most seams. A 4-thread
over-lock stitch gives additional

needle cover stitch will give additional
strength, stability and excellent finish to
the garment. The single needle
machine is used for
placket & collar
attachment of the Polo
Shirts, taping from
shoulder to shoulder,
which will re-enforce
construction and also for attaching
labels. At every stage of stit1ching, QCs
check to make sure that high quality
standards are maintained.
Once the garment is stitched, each piece
is manually checked twice for any
defects, and measurements. Then they are ironed; tags are attached
