Cutting is an extremely dangerous process.
Computerized factories use laser to cut the
fabric, eliminating much of the danger.
Cutting can be contracted out to cutting
factories.

Clothing production:
1.
Line
assembly relies heavily on hierarchy with each person assigned a task or tasks.
Most know only the task they perform. Most factory personnel do not understand
the process from start to finish. There are various methods used to produce
patterns and to sew garments. Most home sewing and custom methods cannot be
used in the industry.
Industrial
methods can best be described as low-level engineering. Patternmaking must be
to 1/32 of an inch, sewing to 1/16 of an inch. Grade rules determine the fit
throughout a size range. Patterns must be drafted to the grade-rule
measurements. Sewing must be sewn on gauge to maintain the grade-rule fit and
the customers’ fidelity.
2. The steps in the process vary, depending on the type of garment being manufactured.
3. Sewing skills vary from person to person and from factory to factory. An operator may be proficient at setting sleeves, but not know how to set a collar. A patternmaker may not be able to sew samples, a sample maker may not be able to draft patterns.
4. Factory personnel (and design room personnel, once out of college) learn their trades by oral tradition. Books aren’t used. No one sits in a class. The instructor (usually the forelady) sits by the new trainee who observes, learns, and memorizes the sewing procedure.
A
newly hired sewing machine operator is first instructed how to sew on gauge.
The instructor gives the trainee strips of fabric to sew on gauge. The trainee then
practices alone until proficient - about an afternoon’s length of time.
After
learning gauge sewing the trainee is taught the easiest step in the
manufacturing/sewing process. Once the second lesson is learned – usually
within an hour or so, the trainee is now sewing on the line. It’s possible for
one instructor to train as many as 10 new seamstresses at a time.
5. Before a clothing style is sent to the factory every detail must be tested and written down in the designing department, then checked and rechecked for possible error. These instructions are sent with the patterns to the factory. The factory follows these procedures to the letter, conferring with the designing department when necessary. Factories are often required by independent designing departments to first make a sample for approval before being given the OK to manufacture the garment. Several factories may bid on the contract, each sending in a sample as part of the bidding.
Design room
procedures include:
designing the type of clothing to be made, drafting the patterns, making
samples, and grading the patterns. A set
of graded patterns, a pattern check (sample garment cut and sewn from the
sample size) a Cutter’s Must list (of the pieces that make up the garment) and
markers (layouts) are sent to the factory.
Some of this may be digitized if the factory is computerized.
Designing
departments cut and sew sample garments. If the company also has a couture
line, those garments may also be cut and sewn in the designing department. But
this is unusual.
7. If a factory switches to another clothing style new machinery may be needed. An industrial sewing machine costs from $1000 used, up to $10,000, maybe more. For this reason and many others factories specialize in particular types of clothing. Any change in production often requires relocation of machinery as speed is essential. Since machinery is bolted down to the floor, even that small a change requires financial justification.
8. Mass-production produces huge quantities of clothing. Factories traditionally cut 1000 garments at a time, although small shops may cut as few as 500 at a time. A shop of 80 seamstresses can produce 450 or more lined sleeveless jumpers with back zippers and ties in a day. A sample maker can sew 6 in one afternoon.
A
T-shirt takes 5 minutes to sew. If the factory operates 6 hours a day, 5 days a
week, each operator can produce 72 shirts a day, 360 a week. A small factory of 10 operators can produce
3600 T-shirts a week.
9. Pricing is determined by cost of materials.

Suggested brief evaluations to
determine if a project is feasible:
1.
Survey a selected small typical
group of potential factory workers whom you hope to train - maybe 10. Keep a chart of
the answers.
a. Ask if they have ever sewn.
b. Ask if they would be interested in sewing in a small factory.
c. If they are interested, have them sew fabric strips on gauge on a basic industrial sewing machine (industrial, single-needle, straight-stitch machine with a bobbin.)
d. If they are still interested, have them sew a few muslin samples, such as a mock up sleeve set or collar to determine if they have hand dexterity, or can develop it.

d. If they are still interested, have them sew a few muslin samples, such as a mock up sleeve set or collar to determine if they have hand dexterity, or can develop it.
2. Evaluate
the machinery available.
One must look carefully at what machinery is needed for suggested projects and
then try to choose projects that can be sewn with existing machinery. Most industrial sewing machines do one operation. Some can be switched to additional operations, but a mechanic must do this.
3.
Write a brief business plan
that sets up the proposed product’s manufacturing procedures. Look carefully at what
machinery is needed for suggested project(s), then try to choose projects that
can be sewn with existing machinery.
a. Write the step-by-step
procedure required to sew the garment. List
the machinery needed to do each operation, availability, & cost of that
machine.
For example: a T-Shirt
from a reputable mail order company
1. Hem pocket with cover stitch machine
2. Sew pocket to front shirt with
single-needle lockstitch machine
(a basic straight
–stitch sewing machine with a bobbin)
3. Lockstitch the shoulder
4. Lockstitch neckband closed
5. Cover stitch neckband
6. Band back neckband and shoulder
– probably a cover stitch machine
7. Set sleeves with cover stitch machine
8. Mock-stitch side seam/sleeve seam
9. Hem body and sleeve with cover
stitch machine
b. If making the proposed garment looks
feasible, list the machinery needed and its cost
Machinery needed to make the T-Shirt:
1. Lockstitch (straight stitch
machine with bobbin)
2. Cover stitch
3. Mock-stitch (4-thread overlock
– NOT a safety-stitch)
4. A fourth sewing machine may
have been used to finish the shoulder seams – there are so many different types
of industrial sewing machines, I can’t be sure.
c. To make sure manufacturing this
garment will be profitable add:
1. Layouts with yardages
2. Cutters Must list of all fabric
pieces
3. Time chart for sewing each step
of operation
4. Cost sheet
4.
Determine whether there are national
markets for this clothing. Reps
wholesale garments to stores throughout the USA. Asking a rep if the product
will sell nationally may yield valuable information about the validity of this
project. At least one rep, probably more will be needed to market the clothing,
as they serve different regions throughout the USA. They often represent more
than just one manufacturing company. Since they work on commission, it’s in
their interest to sell as many garments as possible.
Attending
a trade show at the Javits Center in NYC will also yield information about the
feasibility and market for the intended garments. Some reps sell clothing for
several manufactures at trade shows.
Other
factories are competing for work. The industry does not copyright most
garments. What matters is marketing and price competition: getting something
new on the market first and keeping the price below the competitor’s.
Any
garment can be copied and off a competing factory’s line within a week. Price
matters to the consumer. Companies often compete by reducing their product’s
wholesale price by $.50 ($1.50 retail). This is enough to put a small startup
out of business overnight. Reps have
been known to take a product to another company and ask them to produce it at a
lower price.
