Cutting and sewing

Working principle of Straight Knife as Cutting Accessories

 The Working Principle of Straight Knife of Garment Manufacturing which is used on Cutting Section are as belows-

1. Firstly, switch on this cutting machine.
2. Then, place the cutting machine at any corner of the table.
3. Then switch on the blade.
4. Then the operator moves the machine by hand through the stationary fabric layers and cut along marker lines until finish the marker.
Disadvantages of Straight Knife as Cutting Machine:
1. Blade deflection occurs so quality may be hampered.
2. Skill hand required.

Methods of Cutting Fabric & Uses of Scissor

There are three major methods that used in our garment industry.

1. Fully Manual: By using scissor. In this method it is not possible to cut fabric directly from the lay.

2. Manually Operated Powered Knife Method.
3. Computerized Method.

Uses of Scissor in Garment Industry:

In Sample Section:
1. To cut fabric for sample garment.
2. Used for pattern cutting & making.
In Cutting Section:
1. Not possible to cut fabric directly from the lay.
2. To cut roll end during fabric processing.
3. Used for faulty parts replacement.
In Sewing Section:
1. For thread cutting.
2. Used for label cutting if needed.
Finishing Section:
In finishing section scissor is used for packaging and cartooning purpose.

Drill Cutter & Die Cutter | Cutting Machine of Garment

Drill Cutter:

1. This is a secondary cutting machine.
2. Drill holes are helpful guide to positioning of various items.
3. Used for positioning of pockets, buttons & button holes, etc.

Die Cutter:

1. Mainly used for mass production of slow change items.
2. Dies having the exact shape of the garment pieces.
3. Some dies are sued over a long period.

Advantages of Die Cutter:

Very accurate and excellent for small components.

The Knife Band | Features of Band Knife Machines

The features of the Band knife which is used in cutting section of Garment manufacturing are described below:

Features of Band Knife Machine:

1. This machine worked as saw mill technique.
2. Not possible to cut fabric directly from lay.
3. Block pieces of fabric required in bundle form to cut by this machine.
4. Blade moving vertically through a flat working table.
5. Machine remains stationary and fabric is moveable.
6. Specially used to cut small parts more accurately.

Disadvantages of Band Knife Machine:

1. Fabric wastage is high.
2. Work load high.
3. Push cutting needles in better vision but is more dangerous.

Cutting Tools that mostly used on cutting department in garment industry

Here is a list of cutting tools and accessories often used on cutting department in garment industry:
1. Scissor

2. Straight Knife.

3. Band Knife

4. Round Knife

5. Die Cutter

6. Computerized Knife Cutter.

7. Computerized Laser Cutter.

8. Drill Machine.

Here Scissor is used in 100% cases in cutting section. Straight Knife is used in 100% cases for bulk cutting directly from lay cutting.

The drill machine is specially used for position marking on the fabric that would be cut for making garment.

CUTTING AND SEWING OF TOWEL

In this stage, towels pass through five steps:
Longitudinal cutting
Longitudinal hemming
Cross cutting
Cross hemming
and of course inspection.

Cross Cutting Machine

These processes are achieved by scissors and standard sewing machines by workers or by machines specialized in towel cutting machines in most modern mills. The automatic machines which can carry out some of or all of these processes. Lengthwise cutting machines are used for the first step of this stage, longitudinal cutting of towels which have been produced on the weaving loom as several panels joined side by side. In these machines, there are several cutters which cut lengthwise between the towel panels in order to separate them. The cutting process can be carried out by means of a pressing blade on a motorized roll in the lengthwise cutter.
Next, longitudinal hemming is achieved by lengthwise hemming machines, most of which are usually equipped with two 401 chain stitch sewing machines, one on the right side and one on the left side, for the longitudinal hemming of towels.
After lengthwise hemming, towels pass through cross cutting as the third step. Labels can be attached during cross cutting and hemming. Transversal cutting machines carry out product stacking and automatic discharge.
The cut product is stacked in layers one on the other.
Most American wash cloths are sewn by hand as they require a special stitch around the rounded corners, the European wash cloth is square and therefore can be done an the automatic side and cross stitching machines.

Hand Sewing Wash Cloths

After the towels are stacked, they are inspected and folded according to the customers specifications. Most retailers will have independent inspectors come to the factory and take representative samples of the towels for measurement and weight. Often they will also take samples and send them to outside laboratories to be tested for washing and use to be sure that the towels so in fact perform to their requirements. Some of the largest and most reliable factories will do this testing themselves to be sure that the products they are making are up to their own standards. Then they are put into cartons and sealed and marked with the carton markings as per the customer request.

Inspection and Folding

From the Packing room the cartons of the towels are usually stored for a short time in a warehouse so as to accumulate the entire order from the retailer. Once the order has been completed, the cartons are put into ocean containers and shipped to the closest ocean port for loading on a container ship.
Between three to four weeks later the container is delivered to a port in the US. Customs brokers with with the US Customs officials to clear the containers and have them picked up by either trucks or train and delivered to the retailers distribution center.
To give you an idea as to how much toweling is being made, in the larger factories in the world, each factory is shipping between 15-20 containers per day. Each container will hold about 15 tons of towels. That is a lot of towels.
From here our tour of the towel factory has ended, but we still have much more to tell you, so be sure to go forward to the Types of Towels to learn about all of the different kinds of towels you will find in the retail stores and on line.
After that please check out the World Factories to see the largest towel factories in the world as well as the names of some of the better smaller factories.
