Types of garment production systems

Garment production system is defined as a structure in which machines, material handling, people and production processes are integrated to convert fabric into garments.

Typed of garment production systems differ from each other by following factors:

  1. How many operations does one sewing operator perform?
  2. How many pieces flow together in the sewing line?
  3. How are material transferred from one workstation to other?
  4. How many pieces flow together in the sewing line?
  5. How many machines does one sewing operator operate?

Reduce Matching Time in an Assembly sewing line using workaid

I was doing my apparel internship with one of the top jacket manufacturer . There I found that lining – Body – Sleeve matching was one of major bottleneck in production. Matching operator would pick up sewn front, lining and sleeve hang them all up on an iron rod. Then she would pick up one front body piece and search for matching lining and sleeve. At one point of time there used to be atleast 50-100 lining and sleeve. So finding a particular number lining , sleeve from a stack of 50 -100 would take a lot of time . Clearly this is a highly inefficient process which affects loading in assembly line . To solve this matching /pairing problem many apparel manufacturers make use of pigeon holes.

Line balancing in garment industry and how it can be improved ?

line balancing in garment industry is the technique of levelling output of every operation in a garment sewing production line.

The main objectives of balancing the line is to produce the same expected output at every process of an assembly line .There should neither be accumulation of work between two process nor absence of work between the processes. It is important to maintain this balance because in an assembly line output of one process is the input for other.

If a production line is not balanced then there would be following production problems:

Difference between Lycra and Spandex

Difference between Lycra and Spandex has baffled many people in this post we are going to compare spandex and lycra to clear the confusion.

Specific garments or clothes come with inbuilt stretchability qualities. This excellence of the material is due to the existence of spandex.

The content of spandex present in the material is often interchangeably used with Lycra. Most people generalize or evaluate lycra as the synonym of spandex. However, there is a minor distinction between Lycra and Spandex.

Acceptable Quality level(AQL) sampling for garments quality inspections

Inspecting 100 % of the garments is time taking and practically impossible for manufacturers or buyers as the order quantities are higher in the garment industry .So there is a need to mathematically find out the optimum number of products (garments in this case) which can be inspected to judge the quality of the whole order. That is where AQL sampling comes to play.

How to calculate Weighted average SAM or weighted average SMV ?

Whenever there is a need to find the average SAM, It becomes quite clear that simple average doesn’t give us the right picture. This is because simple average divides the SAM equally between all the styles. This division is wrong because there will be some styles with bigger order Quantity and some styles with lesser order quantity and the effect of order quantity will not be reflected in the averaged SAM. Therefore we need to calculate weighted average SAM whenever there is need to find average. Continue reading “How to calculate Weighted average SAM or weighted average SMV ?”
