Page 64 - ... which can be spun into a yarn or made into a fabric by interlacing in a variety of methods, including weaving, knitting, braiding, felting, and twisting.
Page 7 - By using various combinations of three basic weave patterns, ie, plain, twill, and satin, it is possible to produce an almost unlimited variety of fabric constructions.
Page 42 - Surface is smooth and level such that any shallow depressions and humps do not exceed 6 in. in depth and height. All larger depressions are filled. Alternatively, a smooth working table may be placed. Subgrade has been cleared of obstacles larger than small Moderate to moderate-sized tree limbs and rocks.
Page 41 - Minimum-Use value in weaker principal direction. All numerical values represent minimum average roll value (ie, test results from any sampled roll in a lot shall meet or exceed the minimum values in the table). - Stated values are for noncritical, nonsevere conditions.
Page 65 - ... is an angle the tangent of which is equal to the ratio of axes of the ellipse characterizing the state of polarization. (The sign of...
Page 69 - A planar structure produced by interlacing two or more sets of yarns, fibers, rovings, or filaments where the elements pass each other essentially at right angles and one set of elements is parallel to the fabric axis.
Page 66 - D 4523 nonwoven fabric, n. — a textile structure produced by bonding or interlocking of fibers, or both, accomplished by mechanical, chemical, thermal, or solvent means and combinations thereof.
Page 7 - ... that are bundles of tapelike fibers still partially attached to each other. Such bundles are film strips that have been nicked and broken up into fibrous strands. Knitted geotextiles include two types: the classical knits and the insertion knits. Classical knits are formed by interlocking a series of loops of one or more yarns to form a planar structure. The way the loops are interlocked identifies the type of knit, such as jersey. The knitted geotextiles of the classical knit type are highly...
Page 5 - The first step consists of producing linear elements such as fibers and yarns. The second step consists of combining these linear elements into planar structures usually called fabrics.
