Unit 3 Lecture 17 Topic 2 Flashcards
Warp yarns:
The yarns that are woven in a lengthwise direction. They are also known as the ‘ends’.
Weft (filling) yarns:
Yarns that are woven in the crosswise direction. They are also termed the ‘picks’.
Woven fabrics are produced on _____.
Looms
What direction is the ‘bias’?
The diagonal direction of fabric. The true bias is at a 45 degree angle to the lengthwise grain.
Selvedge (self-edge):
Finished warpwise edges.
What are the two sides of fabric?
The face (right) side and the back (reverse) side.
Fabric face:
Face is the side seen during wear and use. It is usually more attractive and may be more lustrous, brighter, and have more texture with a possible design or print.
On-grain:
When warp and weft yarns intersect at right angles to each other.
Off-grain:
When yarns have shifted during manufacture (dyeing, printing, finishing, etc.) causing skew/twisting in the drape of the end-use product.
Fabric count:
The number of warp and weft yarns per square cm of
fabric (cm^2), often reported per square inch.
Balanced:
When the number of warp yarns is similar to the number of weft yarns.
Unbalanced:
When the number of yarns is much greater in one direction than the other.
Fabric weight:
The grams per square meter (g/m^2) of fabric, sometimes referred to as “gsm”. It can also be reported as the amount of ounces per square yard (oz/yd^2), or sometimes just shortened to ounces or “oz”.
Top weight:
Shirts, blouses, dresses.
Bottom weight:
Pants, skirts.
