Fashion Designer Materials & Techniques 5

Question 1

What is the main difference between woven and knit fabrics in terms of stretch?

Accepted Answer

Woven fabrics have little stretch on grain; knits stretch due to their loop structure

Answer

Woven fabrics are relatively stable on grain (stretching only on the bias), while knit fabrics stretch in multiple directions due to their interlocking loop construction.

Question 2

Which dyeing method involves tying, folding, or clamping fabric before dyeing to create resist patterns?

Accepted Answer

Tie-dye (tie-resist dyeing)

Answer

Tie-dye and shibori are resist-dyeing techniques where sections of fabric are physically prevented from absorbing dye by tying, folding, or clamping.

Question 3

What does 'pre-shrinking' fabric before cutting accomplish?

Accepted Answer

It removes sizing and prevents the finished garment from shrinking after washing

Answer

Pre-shrinking (or pre-washing) removes residual shrinkage from fabric before cutting so the finished garment maintains its size through subsequent laundering.

Question 4

Which seam finishing technique uses an overlock machine to simultaneously trim and encase the raw edge of a seam allowance?

Accepted Answer

Serging (overlocking)

Answer

A serger/overlocker cuts the seam allowance edge and wraps it in thread loops simultaneously, creating a clean, professional finish that prevents fraying.

Question 5

What is 'nap' in fabric, and why does it matter for cutting?

Accepted Answer

The directional surface texture or pile that reflects light differently when viewed from different angles

Answer

Nap refers to a fabric's directional surface (pile, sheen, or print) that looks different depending on which direction you view it, requiring all pattern pieces to be cut in the same direction.
