leather bag.
Answers
Answer:
Preparatory Stage
The first step involves editing and cutting of unwanted raw material/skin. The raw material/skin is then treated from one of the several existing techniques. E.g includes Soaking, Liming, Splitting, Bleaching e.t.c
2. Tanning
The second and most important step is Tanning. It involves converting protein of raw material/skin into a stable material. After tanning the material dries out to a flexible form that does not become putrid when wetted back. Based on the requirement of end application several tanning techniques exist. One of the most common techniques includes chromium.
Other techniques include: Brain tanning, Tannin tanning
3. Crusting
Crusting is used to make the material thin and lubricated. It includes dying and softening operations that involve further sub steps.
BAGS STITCHING/MANUFACTURING
Bag manufacturing process involves the following sub processes:
1. Cardboard Pattern
First of all the card board is cut into different parts. These parts are joined into a prototype of the bag.
This helps in estimating the amount of leather required for the bag and gives an abstract overview of the end product.
2. Leather Cutting
After the prototype is approved, the leather is cut into identical pieces as that of step 1.
3. Stitching & Lining
These pieces of leather are than stitched together neatly. The inside is accustomed with the lining. Requirements for zipping or locking are also fulfilled in this step.
4. Waxing & Polishing
The bags are than waxed and polished into their desired color & look.
5. Quality Check
The quality control department thoroughly examines for minor defects. If needed the bag is sent back to the production department for minor adjustments.
