Clothing and Textile MCQ Questions and Answers

The correct answer is Option B: Both A and R are correct

Let's break down why:

Assertion (A): The most suitable method of printing with disperse dyes is transfer printing.
This is TRUE.
Disperse dyes are a type of dye that are commonly used on synthetic fabrics like polyester.
Transfer printing is a great method for disperse dyes because it uses heat to transfer the dye onto the fabric.

Reason (R): Disperse dyes sublime when heated to high temperature.
This is also TRUE.
Sublimation means that a substance goes directly from a solid to a gas, skipping the liquid phase.
Disperse dyes do this when heated, which is what makes transfer printing work so well.

Why it works together:
Because disperse dyes sublime when heated, we can use that property in transfer printing.
The dye is printed onto a special paper and then heat is applied.
The dye turns into a gas and transfers onto the fabric, creating the print.

Therefore, both the assertion and the reason are correct, and the reason explains why the assertion is true.
