Objectives: The objective of the chemistry course is to acquaint the students with the
basic phenomenon/concepts of chemistry, the student faces during course of their study in the
textile industry and engineering field. The student with the knowledge of the basic chemistry
will understand and explain scientifically the various chemistry related problems in the textile
industry/engineering field.

Outcome: After learning basic concepts of chemistry, the student will be able to select and apply proper chemicals in manufacturing, dyeing and finishing steps of fabrics. The students with the knowledge of the basic chemistry will find out the reaction related problems in the engineering field and hopefully they will be able to solve those problems.
