Yarn Dyeing: 
Yarn dyeing is a special type of dyeing process. This dyeing process is slightly difference from woven or knit dyeing. Dyed yarns are used for making stripe knit or woven fabrics or solid dyed yarn fabric or in sweater manufacturing. Yarn can dye in two form, package or hank form. Flowchart of yarn dyeing can be divided into three stages. Preparatory process, Dyeing and After-treatment process.

Quality: 
Quality is a relative term. It means customer needs is to be satisfied. Quality is of prime importance in any aspect of business specially of export oriented products. Customers demand and expect value for money. As producers of apparel there must be a constant endeavor to produce work of good quality. Process flow chart of quality section of garment is given below.

Garments Quality Control: 
Quality is a relative term. It means customer needs is to be satisfied. Quality is of prime importance in any aspect of business. In the competitive world no alternative of quality. Worlds trend is now quality not quantity. In the apparel business severely maintain quality of products. In this case, buyers satisfaction is the primary and basic goal. For maintaining quality of garments, quality is strictly control in garments industry. In this article, I will give a flowchart of garments quality control.
Quality Control System in Garments Industry
 
Flow Chart of Quality Control System in Garments Industry:

Check the batch information compare with the fabrics information’s. 
↓ 
Match the shade with the bulk production fabrics. 
↓ 
Check the running shade among the roll or roll to roll.( as per guide line). 
↓ 
Check the GSM, DIA and hand feel.(as guide line). 
 
Check the shrinkage (as guide line). 
↓ 
Check the any marks like sinker, needle, DIA, crease mark etc. 
↓ 
Check other faults. 
↓ 
Make report, Discussed with the respective persons to take actions. 
↓ 
Make grading as guide line. 
↓ 
Delivery the okay goods to the Stores. 
↓ 
Reject goods send to MIS store. 
↓ 
Follow up.

Knitting:
There are three types of fabric manufacturing process. They are weaving, knitting and non-weaving. Knitted fabric produced by loop forming. Such type of fabric huge demand in present world. For manufacturing of knitted fabric, process flow chart of knitting technology are given below.

Dispatching

Unload Garment is a basic need of human being. It's manufacturing process is complicated. Garment/Apparel manufacturing processing depends on some steps and techniques. It starts from order receiving and will be end to dispatching shipment of the finished garments. A process flow chart helps to understand how raw materials are moved from one process to another process until raw materials are transformed into the desired product (garments).

In details apparel manufacturing sequence are given below:

Operation
Job
Method

01. Design/sketch
It is given by buyers to manufacturers containing sketches including measurements of the style
Manual/computerized   

02. Basic block
Without any allowance
Manual/computerized

03. Working pattern
Assimilating of diagram of net dimension on paper each and individual part which is called pattern and when we move with it throughout the  whole manufacturing processes. We term it working pattern.
Manual/computerized

Manual/computerized
04. Sample making
After getting all the speech the sample is made and sent to the buyers for approval to rectify the faults.
Manual

05. Basic manufacturing difference
The critical path is identified i.e the problem during the several operations.
Manual

06. Approved sample
After rectify the faults, sample is again sent to buyers. If it is ok, than it is called approved sample.
Manual

O7. Costing
  • Fabric required
  • Making charge
  • Trimmings
  • Profits
Manual

08. Production pattern
Add allowance with net dimension.
Manual/computerized

09. Grading
It is done according to different size.
Manual/computerized

10. Marker making
Maker is a thin paper which contains all the components of all sizes of a particular style.
Manual/computerized

11. Fabric spreading
Fabric is spreaded in lay form.
Manual/computerized

12. Cutting
To cut fabric according to the dimension by special types of cutter.
Manual/computerized

13. Sorting or bundling
Sorting out the component according to size and for each size make individual bundle.
Manual

14. Sewing
Sewing is done by different types of machines by the operation. Quality inspection is also done in that time
Manual

15. Ironing and finishing
Garments are treated by  steam. Also several finishing processes are done for example extra loose thread cutting.
Manual

16. Final inspection
Should meet specs given by buyer.
Manual

17. Packing
Poly packing.
Manual

18. Cartooning
After packing the garments are placed in a hard paper box .for export so as to minimize damage. The cartoons contain all the information over the box according to buyer specs.
