Micro Project
- Importance of pretreatments: Collect various pretreated samples of polyester and carry out dyeing under sim conditions and compare dyeability.
- Dyeing of polyester, nylon and acrylic: Dye different varieties of polyester/ nylon/ acrylic with same dyes a dyeing conditions, compare their dyeuptake and find out fastness properties.
- Dyeing of Different commercial blends of polyester, nylon and acrylic: Collect different commercial dyed b from different industries and reproduce the same in the laboratory.
- Dyeing machineries used in industries: Collect information from different manufacturers of machineries use dyeing of synthetic fabrics and compare their working, structure and techno commercial importance.
