Petersham is utilized in couture sewing as a form of interfacing as way to stabilize waistbands.

Grosgrain is a plain weave corded [a] fabric, with heavier cords than poplin but lighter than faille, [2] [3] and is known for being a firm, close-woven, fine-corded fabric. [4] Grosgrain has a dull appearance, with little luster in comparison to many fabric weaves, such as satin, often used for ribbons; however, it is comparatively very strong ...
The number of wraps will act as a gauge to assess the thickness of unmarked yarn; for example 12 wraps per inch is 12 WPI, and is used to calculate how much yarn is required for various articles, [3] so that 12 is equivalent to 8 ply (worsted weight, medium weight) yarn.
A paired difference test is designed for situations where there is dependence between pairs of measurements (in which case a test designed for comparing two independent samples would not be appropriate). That applies in a within-subjects study design, i.e., in a study where the same set of subjects undergo both of the conditions being compared.
The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm ...
