A cotton fabric is printed using resist style with a reactive dye for ground colour and a chemical resist agent. Amongst the following, the correct statement(s) is/are:
Show Hint
In resist printing, the resist agent prevents dye absorption in certain areas, and it is usually acidic in nature to neutralize reactive dyes.

- Printing is followed by dyeing
- Dyeing is followed by printing
- The resist is acidic in nature
- The resist is alkaline in nature

The Correct Option is A, C
Solution and Explanation
Step 1: Understanding resist printing.
In resist printing, the resist agent is applied to the fabric first to prevent the dye from being absorbed in certain areas, leaving those areas undyed during the subsequent dyeing process. Therefore, printing is followed by dyeing.
Step 2: Nature of resist agent.
Resist agents are typically acidic in nature as they inhibit the dye's ability to react with the fabric in the printed areas. Acidic resist agents neutralize reactive dyes, preventing them from bonding with the fabric.
Step 3: Summary.
Thus, the correct sequence is printing followed by dyeing, and the resist agent is acidic in nature.

- Consider a cationic and an anionic softener both having linear alkyl chains. Upon application on cotton fabric, the orientation of the softener molecules on fabric can be described by the following statement(s):
Group I indicates chemical agents and Group II indicates their functions. Match the agent with its function.
- For a textile industry, the revenue of selling \( x \) tons of yarn is \( R(x) = 4x \) and the cost of producing \( x \) tons of yarn is \( C(x) = 10 + 2x + 3x^{2/3} \). The industry decided to calculate the break-even (when revenue is equal to the cost) for \( x \) tons of yarn using the Newton-Raphson method. Assuming the initial break-even of 8 tons, the break-even (in tons) after the first iteration is:
- High drape coefficient of fabric indicates:
