Desizing
Desizing is an important first step in textile processing where manufacturers remove the protective starch coating (called 'size') that was applied to yarn during weaving. This coating helps protect threads during weaving but needs to be removed before dyeing or printing can take place. Think of it like removing a protective layer from fabric so it can be properly colored or treated. It's similar to how you might need to remove a protective film from a new phone screen before using it. When candidates mention desizing experience, it means they understand this crucial preparatory process in textile manufacturing.

Example Interview Questions
Senior Level Questions
Q: How would you improve the efficiency of a desizing process while maintaining quality?
Expected Answer: A strong answer should discuss monitoring enzyme/chemical concentrations, temperature control, timing optimization, and quality testing methods, while considering cost and environmental impact.
Q: What safety measures would you implement in a desizing department?
Expected Answer: Should cover chemical handling procedures, protective equipment requirements, emergency protocols, staff training programs, and environmental compliance measures.
Mid Level Questions
Q: What are the different methods of desizing and when would you use each?
Expected Answer: Should explain enzymatic desizing, oxidative desizing, and acid desizing, with basic understanding of which method works best for different fabric types.
Q: How do you verify if desizing is complete?
Expected Answer: Should mention iodine drop test, water absorption test, and visual inspection methods, explaining why each test is important.
Junior Level Questions
Q: What is the purpose of desizing in textile processing?
Expected Answer: Should explain that desizing removes starch/size from fabric that was used during weaving, making the fabric ready for dyeing and finishing.
Q: What basic safety precautions should be taken during desizing?
Expected Answer: Should mention wearing proper protective equipment, following chemical handling guidelines, and basic machine safety procedures.
