Question

Which of the following terms refers to the density of knitted fabric measured by the weight of the given fabric?

• A. Ends per Inch (EPI)
• B. Picks per Inch (PPI)
• C. Grams per Square Metre (GSM)
• D. Thread Count

Answer 1

The Correct Option is C

In the context of knitted fabric, the term that refers to the density of the fabric measured by the weight of the given fabric is "Grams per Square Metre (GSM)." This is a standard metric used to describe how much a fabric weighs for a specific area. A higher GSM number indicates a denser, heavier fabric, while a lower GSM suggests a lighter fabric.

Explanation: 

• Ends per Inch (EPI): This term is used to denote the number of warp yarns in an inch of woven fabric. It refers to fabric construction rather than weight.
• Picks per Inch (PPI): Similar to EPI, this term is used for measuring the number of weft yarns in an inch of woven fabric, also related to fabric construction and not weight.
• Grams per Square Metre (GSM): This term measures the weight of fabric over a given area, specifically a square meter, making it the correct answer to the question.
• Thread Count: This refers to the number of threads per inch in woven fabrics and is generally used to describe the quality and fineness of the fabric rather than its weight.

Answer 2

Grams per Square Metre (GSM) refers to the density of a fabric, measured by its weight. It indicates the weight of the fabric in grams for a square meter area, which is used to determine the fabric's density.

Other options:

• Ends per Inch (EPI): Refers to the number of yarn ends (threads) per inch in a woven fabric.
• Picks per Inch (PPI): Refers to the number of picks (weft threads) per inch in a woven fabric.
• Thread Count: Refers to the number of threads woven into a fabric in one square inch, but it is usually used in the context of woven fabrics and not as a direct measure of density.

The correct answer is (C): Grams per Square Metre (GSM).
