Sewing needle

1. SEWING NEEDLE
A sewing needle is a long slender tool with a pointed tip. The needle must be able to penetrate
the material being sewn, by pushing the yarns aside according to the application, without damaging
it. The various parts of the needle are: The shank, the shoulder, the blade, Long Groove, Short
Groove, The eye, the point and the Tip.

3.  Parts of needle


1. Shank
The shank is the upper portion of the needle that is inserted into the machine. The front is rounded
and the back is flat. Home sewing machine needles are composed of a flat and a round side, to
assist in always having the needle in the correct position.

2. Shaft
The shaft is the lower portion of the needle that begins at the base of the shank and extends to the
point. The needle size is determined by the shaft diameter.

3. Groove
The groove is the indentation located on the front of the needle. The thread is protected in the
channel as the needle passes through the fabric.

4. Scarf
The scarf is the indentation on the back of the needle above the eye. The scarf allows the bobbin
thread to pass closely to the needle eye catching the needle thread to create a stitch.

5. Eye
The eye is the hole in the lower portion of the shaft. The thread passes from the front to the back of
the needle through the eye. Select a needle with the appropriate size eye to accommodate the
thread you are using. The thread should flow freely through the eye.

6. Point
The point is the tip of the needle that penetrates the fabric. Needle points are designed to penetrate
different fabric types.

4. 1. Needle Sizes:

Needle packages are marked with two size numbers. The higher number is the European metric
system and defines the needle shaft diameter in fractions of a millimeter. The lower number is the
American numbering system.




2. Types of needle: (on the basis of points)

1. Cloth point: Cloth point needles are for all woven fabric. The cloth point is especially helpful
when sewing straight lines and tasks such as tops stitching.




 Accute point: used for elastics attachments. It is not used for light weight or medium weight
fabric as it may damage the fabric.
 Regular point:it is popularly used needle.

5. 2. Ball Point: Ball Point is more rounded than Universal, designed to slide between yarns of
knit fabrics without snagging.





3. Universal needles can be used with woven or knit fabric. The point of a universal needle is
sharp yet very slightly rounded giving it the characteristics of a sharp and a ballpoint needle.


3. Cut Point Needles has Sharp tips and is used for sewing leather and plastics. It modifies
set of stitching and appearance of seam. It also creates decorative effects.

 Narrow wedge points: it cuts at right angle to seam direction. With the help of this needle
high stitched density is used.
 Narrow reverse twist point: Produces incisions at 45 degrees to seam direction. The seam is
slightly turned left on the surface of the material.
 Cross point: Incisions is along line of the seam. Requires large stitch length. Incisions
spaced far apart. Used for heavy decorative seams. Stitche shave straight appearance.
