Cloth or yarn strips attached to an airfoil so that their movement can be observed during a test of the air flow around the airfoil placed in the flow
The process of of creating a pile fabric by punching loops of yarn through a woven or nonwoven backing material
Anchoring the cover of upholstered furniture or mattresses by sewing through the filler Often buttons are stitched on and arranged to form a pattern such as biscuit tufting (rows of squares) or diamond tufting (staggered rows which form an overall diamond pattern)
A form of hooking, yarns are pushed through the foundation of a rug with an electric tufting gun to form a pattern
The fabric of an upholstered piece or a mattress that is drawn tightly to secure the padding, creating regularly spaced indentations
A method of carpet manufacture in which surface yarns are sewn or "punched" through a primary backing material The needles of the tufting machine form loops that are hooked by loopers on the underside of the backing material and which remain loops in level or textured loop carpet Alternatively, the loops are tufted and cut with knives to create cut pile carpet The tufted fabric is then coated with an adhesive to adhere a secondary back to provide durability and stability In the past 5-7 years there have been significant advances in tufting technology, allowing for more intricate patterns and textures
