Garment Manufacturing Process: Step by Step Section Wise

Garment manufacturing is a huge process. All operations are done in different departments in garment industry. It is not possible to describe briefly about apparel production. Garment manufacturing is a sequential processes such as designing, sampling, laying, marking, cutting, stitching, checking, finishing, pressing and packaging etc. In this process, raw materials convert into finished products. I will describe all operations of garment manufacturing step by step in section wise.

Garment manufacturing process in different departments of garment industry are described below:

Sample Section:

There are many types sample are needed when garments are going to make a product.

Types of sample:

  1. First pattern sample
  2. Development sample
  3. Second pattern sample
  4. Counter sample
  5. Salesman sample
  6. Photo sample
  7. Approval sample
  8. Pre-production sample
  9. Production sample
  10. Shipment sample

Types of sampling with their details:

1. First pattern sample:

A design given by buyer and make it physical version of the garment.

Here are some criteria to develop a first sample. They maintain sequence to develop it.

Thinking of a design

Draw in CAD

Pattern

Sample

2. Development Sample:

Which sample are developed by sample section from primary pattern sample.

3. Second Pattern Sample:

Usually designer/ developer always ask for some changes to the first pattern. Second pattern is made as per comments.

4. Counter Sample:

Where first pattern is made on designers artwork, Counter sample is to make not on designer’s artwork, has to follow another sample given by the merchandiser.

5. Salesman Sample:

Salesman Sample is made when PRICE is confirmed and order are on speculation. Buyer held a meeting with its customer and record their response on order quantity per COLOR, SIZE etc. and finally plac order to their vendor.

6. Photo Sample:

Photo samples are made with actual color and material to be worn by models on the event of SHOOTING for catalog.

7. Approval Sample:

It is sent to buyer for his APPROVAL of the conformity that the revision is done correctly. If any fault found then the sample go back to garments.

8. Pre-Production Sample:

When the production accessories come to the garments for the production then garments makes a sample for a buyer. Which is called pre-production sample.

9. Production Sample:

Assurance to the buyer that the bulk is being produced as per specifications.

10. Shipping Sample:

This sample send to shipping inspector. Who give the product to the buyer. It is important sample because of shipping inspector give a note to buyer as sample base.

Sample making procedure:

There are many types of procedure to make sample. But in my garments, they follow this type procedure. I am giving a flow chart to making sample in my garment manufacturing industry.

Cutting Section:

Fabric is a single piece of sheet. When we need garments then we need to cut. Cutting is final step of sample, marker and fabric spreading. Because next process is sewing. When sewing starts then other process also starts.

There are many types of cutting process but in Bangladesh almost everyone uses a same process. And this is manually process. Cutting master cut the fabric by hand cutting machine. There is a big long table where cut the fabric.

garment cutting section
Fig: Garment cutting section

Maker paper kept up on the fabric surface, and cutting muster follow the line and cut the fabric.

Pattern Making Section:

Pattern making process is drawing or art in a flat paper of flat fabric. Basically, garment manufacturing industries make their pattern by using flat paper. Because pattern can easily removable from pattern paper. So, garments industries follow the pattern making process by using paper. In Divine Textile Ltd, they also make their pattern by using paper. And the paper name is pattern paper.

Pattern is important because, it is primary stage of a garments making. If pattern is accurate then the garments should be accurate. Buyers give the size list to the garments, then the garments follow the size and make the pattern with allowance. Pattern is the big issue for every garment.

Marker Making Section:

Marker is a process where every pattern is kept in a long fabric. And this process factory minimized the wastage of the fabric before cutting. Marker increase the efficiency of the fabric.

Types of marker making:

  1. Manually marker making process
  2. Computerized marker making process

1. Manually marker making process:

This is a process where a man done the maker by manually. No computer software is used them. Basically, who do this process he will be very experienced person, and he know how to do this. In my garments the maker making process is manually.

2. Computerized marker making process:

This is hundred percent done by computer, by using CAD (Computer aided design) or many others software.

Effect of Marker Making:

  1. Increase efficiency
  2. Minimize fabric wastage
  3. Maximized using of fabric

Fabric Spreading Section:

In this process fabric laid on a big table which is used for cutting. Fabric spreading is important because of if fabric do not lay properly then outcome product (after cutting) was not correct. So, when the fabric go for production then its make difficulties in making garments. So proper fabric spreading is important for garment manufacturing industry.

When fabric lay properly, they used one kind of clip (Fabric attaching clip) for fixed the fabric. Marker paper also keep up on the fabric surface. Then they attach the fabric with clip.

Types of fabric spreading system:

  1. Automatic
  2. Manual

1. Automatic:

When fabric spread by machine on the cutting table then its called automatic fabric spreading.

2. Manual:

When fabric spread by man on the cutting table then its called manual fabric spreading. In my factory they work in manually.

Cutting Process:

  1. Marker Making
  2. Fabric Spreading
  3. Marker placement
  4. Attaching with clip
  5. Cut the fabric
  6. Numbering
  7. Bundling

Heat Cutting system:

When we need to cut non-woven fabric then normal cutting machine is not suitable for cutting, because non-woven fabric is basically slippery then other fabric. So we need to heat cutting machine.

Types of cutting process

  1. Manual Cutting
  2. Heat Cutting
  3. Lesser Cutting

1. Manual Cutting:

It is a process which done by man is called manual cutting process. In my garments they cut the fabric in manual process. Cutting master give the instruction to worker and worker follow the instruction.

2. Heat cutting:

Basically, a heat machine is used for this process and the machine has copper coil. And electricity passing the coil and it became hot. Then it cut the fabric. This machine is not suitable for cloth type fabric, it is used for non-woven fabric.

3. Lesser Cutting:

A lesser light is used for cutting. It is very expensive cutting method but cutting is very effective.

Sewing Section:

Sewing is big important part of a garment’s product. Without good sewing we cannot introduce our products in worldwide. Sewing is a process where two pieces of fabric are join. Many factors are related with sewing. (i.e.: Needle size, Machine type, Thread count, Worker capacity, Production line etc.) So sewing section is not only fabric join, it is core part of a garment manufacturing industry.

Elements of sewing:

  1. Sewing Machine
  2. Needle
  3. Thread/Yarn

Sewing Machine:

There are many types of machines are used in Divine Textile Ltd. Every types of sewing machines are available here. They (my garments) produce jackets, trousers etc so they need heavy machines for sewing.

List of sewing machine:

  1. Plain Machine
  2. Overlock machine
  3. Bar tack machine
  4. Button hole machine
  5. Button attaching machine
  6. Feed of the arm

Discuss About Sewing Machine:

1. Plain machine:

Plain machine is basically use for attach two fabric. For long stitch this machine is use. There are many brands in plain machine. Some is manual and some is automatic. But every machine works same thing.

Brands:

  1. Juki
  2. Hakkari
  3. Brother

JUKI is a well-known brand in sewing machine. Every company used this machine. Initial power of machine is very good. This machine origin is China. This machine is manual machine. Operators need set the machine, because settings are going change when products are changed.

HIKARI is also well-known brand in sewing machine, and this machine is semi-automatic machine. If one system is input in this machine then no need gives same settings once again. Every data is stored in this machine. Production rate are automatically calculated in this machine.

BROTHER is a Chinese brand, which produce many textile and other machineries. They made manual, semi-automatic, fully automatic machines for sewing. But in my garments, they have used manual machine. This machine is manual but this machine is safe for human. Brother ensure the workers safety. They introduce many devices in this machine for workers safety.

Example: if any needle breakdown then machine automatically gives sound. There are many types of facility in this machine.

2. Overlock machine:

An overlock is a kind of stitch that sews over the edge of one or two pieces of cloth for edging, hemming, or seaming. It is very effective machine for garments good, because without overlocking edge finishing is not to be good. There are many brands available in market but Divine Textile Ltd. use only one brand for overlock.

3. Bartack machine:

Bartack machine specially use for lock stitch. It contains a needle and a bobbin. It produce high density lock stitch in short place. In my garments they use bartack machine to stitch the side of pocket in jacket and pants. Stitch density depends on the GSM of fabric. If the GSM is high then the stitch density is high, If GSM is low then stitch density is also low.

4. Overlock machine:

This machine basically used for protect the edge of fabric and trim the extra part of fabric. This machine used when product is done by plain stitch. Five thread are used in overlock stitch machine. A sharp blade also attaches with the machine. This sharp blade cut the extra part of the fabric and gives a plain finishing in the garment’s products. This machine is very fast machine so need good experienced worker to run this machine, otherwise any types of accident can be happened.

5. Button attaching machine:

This machine basically used for attach button on the jackets or garments goods. It is very high speed machine and this machine can attach up to 60+ button in a minute. In my garments there are two types machine. One is plastic or normal button attaching machine another is steel or clip or tip button attaching machine.

6. Feed of the arm:

Feed of the arm machine is actually a chain stitch machine for chain stitch designs working with sew and stitch. It contains looper instead of bobbin. By this machine, multi thread chainstitch can be produced on garments. By this machine, stitch can be produced on heavy fabrics, like denim or jeans.

Discuss About Needle:

Needle is an essential product for sewing. Only machine cannot sew without needle. Needle made by stainless steel with sharp head. In sewing machine, there are different types of needle is used. In my garments industry I was found three types of needle. Which is used on plain, overlock and bartack machine. Some needles are quite bigger usually it depends on fabric. If fabric is courser then need courser needle.

Needle varies machine to machine:

In JUKI sewing machine the needle name is BP. And needle size is 9,11,14,16,18,20

In Sunstar sewing machine they used, DP, and needle size is 9,11,14,16,18,20

In Overlock machine, the needle size is small then stitch machine. Needle size of overlock machine is DC, 9,11,14,16,18,20

Sewing Process:

In my industry they follow a process to maintain sewing.

Collect fabric from cutting section

Input the fabric into the line

Set the machine settings

  1. These are used by a variety of different people in different settings, so it’s important that you know what to look for when searching for metal detectors. Once you know what you are looking for, it should be easier to narrow down your search for the best metal detector for your needs. You should also keep your prices in mind, so that you don’t overspend.
