Bound seams

Garments made of coated fabrics are used in outdoor sporting activities and would include the construction methods of superimposed, double-lapped and bound seams. Also, welded methods might be employed on highly synthetic fabrics with more than a 60% synthetic blend. Acute needle points are used to pierce the fabric making a small needle hole that... 

Bound seams deliver extra durability and strength (Figure 10.31) to the sewn product. 

Class 3 — Bound seam, constructed by binding one component edge with another narrow component. The seam is produced with a minimum of two pieces of component. One component is limited on one end and the other is limited on both ends (Figure 10.37). 

Bias binding is used as a decorative finish for the raw edges of a fabric and is used either for hemming or as a form of a bound seam where the ends of the fabric are tucked within a tape, so that no raw ends are exposed (Figure 10.46). 

Recent examples of this kind of methodology can be found, for example, in the work of Rebek et al. [10] The catalyst used is a cavitand armed with a Zn salen-type complex (Figure 1.2). The cavitand adopts a vase-like conformation that is stabilized by a seam of hydrogen bonds provided by the six secondary amides. The structure of the catalyst permits a slow dynamic exchange between free and bound guest (reactant) on the H NMR time-scale that is controlled by the folding and unfolding of the cavitand. 

The bulk mineralogy of the coal, also represented in Table III, is characterized by quartz, calcite, bassanite, kaolinite, and pyrite. Bassanite is probably a low-temperature ashing product of organic sulfur fixation with organically bound calcium (13). Pyrite content appears to increase with depth in the seam relative to calcite and kaolinite. 

On either side of the shear zone proper (the term is used here to designate the zone that accommodates most of the fault displacement and is typically bounded by D-shears), a much wider zone of continuous and/or discontinuous (slip) deformation is usually discernible. Faulted monoclinal flexures in shale layers (Plate 3) furnish the most prominent examples of continuous, fault-related deformation. At places, the coal seam is flexed together with an over-lying or underlying shale. Almost everywhere along a fault, a fringe zone of (discolored) shears is observed in the sands (Plate 4). On the downthrown side, the flexed shales are often intersected by these shears... 

It was the first naturally occurring crown ether, and the earliest for which the antibiotic activity could be traced to its ionophoric properties (4). The actins give one-to-one complexes with many alkali and alkaline earth metal ions, with nonactin showing selectivity in the order NH4+ > K+ = Rb+ > Cs+ > Na+ > Ba2+ (5). The first X-ray crystal structure of an ionophore-metal complex was obtained from the nonactin-potassium thiocyanate complex (6). The potassium is bound by coordination to all four tetrahydrofuran oxygens and to the four ester carbonyl oxygens, which creates overall a "tennis ball seam" conformation to the carbon framework as it wraps around the metal. 

Seam BSa is used for edges bound with ribbon or braid, BSb for T-shirt necklines or sleeve edges with knot trim, BSc for neckline or front edges bound with bias-woven material, and BSd and BSe for seaming and binding, respectively.
