Question

Amongst the following, the correct reason(s) for high pilling tendency in a woven fabric is/are:

• A. High twist level in the yarn
• B. Low twist level in the yarn
• C. Finer and stronger fibres in the yarn
• D. Weak and brittle fibres in the yarn

Hint:

Pilling tendency increases with low twist yarns and weaker fibers, as these factors allow for more fiber protrusion and breakage.

Answer 1

The Correct Option is B, C

Pilling tendency in woven fabrics is influenced by the structure of the yarn and the fibers used.

Step 1: High twist level in the yarn.
A high twist level in yarn generally reduces the tendency for pilling because it makes the yarn more compact and less prone to fiber ends protruding from the fabric surface.

Step 2: Low twist level in the yarn.
Low twist yarns tend to have more free fiber ends, which are more likely to protrude from the fabric surface and form pills. Therefore, low twist increases the pilling tendency.

Step 3: Finer and stronger fibers in the yarn.
Finer and stronger fibers tend to reduce pilling because they are less likely to break or fray, resulting in less fiber shedding.

Step 4: Weak and brittle fibers in the yarn.
Weak and brittle fibers increase the likelihood of pilling, as they break more easily and contribute to fiber shedding on the fabric surface.
