Explain button holing machine?


The high
-
speed lockstitch buttonholing machine incorporates an electronically controlled cloth
feeding mechanism. Using a new technology called "active tension" (electronic thread tension
mechanism), the
machine is capable of not only duplicating the same sewing conditions with
ease but also of ensuring upgraded seam quality with consistency.

Write a note on pattern making tools?


PATTERN MAKING TOOLS

When fashion designers, patternmaking designers, or
pattern makers, ......, produce their draping design, or alter the

patterns and garments, the professional pattern making tools are needed:


Pattern Design Ruler


1.


Hip Curve

24” rulers that is shaped into a curve at one end. Used to curve hiplines on s
kirts and pants for drawing curved
hems, hips and other slightly curved areas.


2.


French Curve

Shaped a curve at one end, individual curves are used to shape armholes, necklines, sleeve caps, darts, crotch
seams, lapels, pockets and collars.


3. L
-
Square

With one side longer than the other, shaped like the letter “L”, used to draft slopers and patterns to establish length
and grainlines on patterns and slopers.


4. Straight Ruler

To straight edge with clearly marked measurements rulers (12”, 18”, 24”)


5.

Tape Measure

A narrow, firmly 60” tape with metal tips on each end.

Pattern Notcher

A hand punching tool which provide a 1/16” x 1/4” nick in pattern paper. Used to establish matching
-
point notches
on the outer edges of pattern pieces.

It also cuts through tag board.


Tracing Wheel

A small hand tool with metal point, used to transfer markings from pattern onto fabric with or without tracing paper.


Awl

A pointed tool with a wooden handle. Used to pierce small holes such as to indicate a
pex.


Cloth Weight

Cloth weights are used to weight down pattern pieces or fabric pieces.


Pattern Punch

A pattern punch is used to cut a circular 3/4” hole on pattern papers to enable hanging up by pattern hooks.


Pattern Hooks

Pattern hooks with cord are

used to properly hang patterns.


Pattern Shears

Cutting is extremely important in patternmaking and sewing. Without good cut, the sloper is doomed, so, with a pair
of professional heavy duty pattern shears(12”) that have an extra long shank and heavy blad
es is very helpful for
patternmaking.


Fabric Scissors

Indursty heavy duty fabric scissors: 8”, 10”, 12”, with extreamly sharp blades, good for cutting fabric.


Draping Pins

A size 17 steel satin straight pin. Used to fasten parts and pieces together.


Dra
ping Tape

Professional draping tape, 3/32” width, 49 feet length, with 5 different colors to select. Very easy to curve and line
up.

How do you clean and oil the sewing machine?


Instructions

Things You'll Need



Manual for your sewing machine



Sewing
machine oil



Can of compressed air



Tweezers



Screwdriver



Lint brush

1.


o

1

Unplug your sewing machine.

o

2

Unscrew and remove the needle and foot and put them in a safe place.

o

3

Remove the throat plate on your sewing machine. Unscrew it if necessary and use the
th
roat plate lever to raise the plate so you can remove it. Your machine's manual should
have specific instructions for this.

o

4

Use tweezers and a lint brush to remove all bits of thread, debris or dust in the sewing
machine.

o

5

Carefully blow out the foot pl
ate and bobbin area with compressed air. Do not blow any
debris further into the sewing machine because this could cause problems later.

o

6

Place a tiny drop of sewing machine oil in each of the oil spots on your sewing machine.
Your manual will show you
exactly where these are located, or they will be marked on
your machine.

o

7

Turn the hand wheel several times to distribute the oil.

o

8

Replace the foot plate and press the lever downward to lower it back into place. Replace
any screws that you removed.

o

9

Re
place the sewing machine foot and needle.

o

10

Sew for a minute or so with a piece of paper towel or a scrap piece of fabric to absorb
excess oil. You do not need to thread the machine for this.

Write a note on commercial pattern?


Pattern making

A custom

dressmaker

frequently employs one of
three pattern creation methods. The flat
-
pattern method
begins with the creation of a

sloper
or

block
, a basic pattern for a fitted,

jewel
-
neck

bodice

and
narrow

skirt
, made to the wearer's measurements. The sloper is usually made of
lightweight

cardboard

or

tagboard
, without

seam allowances

or style details. Once the shape of the sloper
has been refined by making a series of mock
-
up garments called

toiles

(UK) or

muslins

(US), the final
sloper can be used in turn to create patterns

for many styles of garments with varying necklines, sleeves,
dart placements, and so on.

Although it is also used for womenswear, the drafting method is more commonly employed in menswear
and involves drafting a pattern directly onto pattern paper using a

variety of straightedges and curves.
Since menswear rarely involves

draping
, pattern
-
making is the primary preparation for creating
a cut
-
and
-
sew woven garment. The initial measurements and adjustments are created on paper as a draft. More
paper is placed over top of the draft and traced off with seam allowance added to these pieces, which will
then be cut out and used to cut out actua
l fabric for sewing. If this draft will be frequently used, a sloper is
created to speed up the production time. A pattern maker would use various tools such as a notcher, drill
and awl to mark the pattern in places.

The pattern draping method is used for
more elaborate and unique designs that are hard to obtain
through the flat pattern method. This is because it is nearly impossible to account for the way a fabric will
drape or hang on the body without an actual 3
-
dimensional test run. It involves creating

a muslin mock
-
up
pattern by pinning fabric directly on a

dress form
, then transferring the muslin outline and markings onto a
paper pattern or using the muslin as the pattern itself.

Pattern grading

Pattern grading is an essential part of pattern making. It decides how patterns increase or decrease
sizes.
According to countries, pattern grading includes USA's, EUR's, UK's, and CHN's. Generally, pattern
grading adjusts for people of different ages and genders. The fabric type also influences the pattern
grading standards.
[1]

And marker makings are the actual full size print out of how the styles are cut on the
fabric. The cost of pattern grading is incomplete without considering marker making.

Define seam. Mention its types?

SEAM

may refer to:



The ICAO airport code for

Chachoan Airport

Sun Enterprise Authentication Mechanism, an
implementation of

Kerberos

protocol for the Solaris
operating system

There are a number of different types of seams that have been developed over the years to do
diff
erent jobs. While many have largely been superseded by the development of machine
stitches that finish as you sew them, and by the development of the overlocker (or 'serger' in
some parts of the world), it is useful to know some of the basic seams types an
d finishes. A lack
of expensive machinery need not prevent you sewing the garments you want. Also, some of the
older methods have never been bettered.


Here I am concentrating on machine sewn seams
using a standard straight stitch machine.

When you have ch
osen your fabric and pattern, you need to think about the most suitable way
to sew the garment together. This will depend partly on the type of fabric, partly on the use the
garment will get, and partly on the finish you want.

There are a few terms that yo
u will need to know so that you can understand what the different
parts of the seam are:



CUTTING LINE:

the line on which the garment is cut out



STITCHING LINE/SEAM LINE:

the line on which the seam is sewn



SEAM ALLOWANCE:

the area of fabric between the stit
ching line and the cutting line. This is
usually 5/8" or 1.5cm. Some patterns allow more in some areas, and some allow less.

Always
check

before making up a pattern.
