Interlaced patterns

In crystals containing no zigzag stacking, the orientations of the polygonal elemental spiral steps may be used as a criterion to identify whether the crystal is twinned or contains stacking faults.

These weaves are frequently, though not exclusively, found in belt filters, either of the vacuum, continuous multi-roll press or of the vertical automatic pressure type. Owing to the interlacing pattern of the threads, it is possible to create fabrics with a measure of a solidity and stability that are ideally suited to filters of the types identified. On the debit side, the cost of weaving such high-density fabrics tends to preclude their use in all but a limited number of niche appUcations. 

Still another variation is shown in Fig. 6.4, right. There the elements are placed on both sides of a thin dielectric substrate in one interlacing pattern, as shown. That approach is currently being used by Mission Research Corporation, Dayton, Ohio. Harris uses elements loaded with finger capacitors (see Fig. 10.4 and associated comments). 

Plain weave is the simplest interlacing pattern, as shown in Fig. 8.22 for jute and coir woven geotextiles in the length of the fabric a warp yam crosses over alternate wefts, and in the fabric width, a weft yarn crosses alternate warps. The frictional contact of the yarns at the interlacing points prevents each yarn slipping from its woven position, and it also increases the stiffness of the fabric. The interlacing causes the warp and weft yarns to have a... 

The compliance is the ability of one native soft tissue to adapt its volume unda pressure variations. Regarding fiber and yam interlacing patterns, fibrous structures have specific stress—strain behavior with initial debulking at low-load level and flien strengthening of more aligned fibers at higher-load level. Stress—strain curve patterns of fibrous tissue are similar to those of soft tissue, which is encouraging to mimic ECM. 

While textile processing previously included almost always three to four successive steps to achieve a 3D structure, from fiber to the yam and then from the yam to the surface and volume arrangement, one more recent way to achieve this is 3D printing and 3D deposit of the fibrous component. Even if it is not the only way to obtain desired and optimized stmctures, it points out the willingness to control all the key parameters of fibrous stmctures. Orientation, distribution, and square density of fiber is aimed to be controlled, as well as the fibers properties themselves, their interlacing pattern, at aU scale levels. 

A method of measuring the TOW has been developed by Sereda and correlated with the corrosion rates encountered in the atmosphere [13]. The moisture sensing elements in this sensor are manufactured by plating and selective etching of thin films of appropriate anode (copper) and cathode (gold) materials in an interlaced pattern on a thin nonconductive substrate (Fig. 9.23). When moisture condenses on the sensor it activates the cell, producing a small voltage (0 to 100 mV) across a 10 Q resistor.

Although interlaced packing of chromatographic peaks is more efficient, the packing pattern is difficult to apply. 

The botanical name Convolvulaceae for the morning glory family derives from the Latin convolvo, meaning interlaced, and describes a growth pattern of intertwining vines wrapping around a support, and is characteristic of the majority of the species... 

The structure of the liquid- liquid interfadal layer depends on the difference in polarity between the two liquids (Kaeble, 1971). Asymmetric molecules of some liquids display a molecular orientation on the interface which is indicative of their structure. Thus, interfacial tension at the octane-water interlace is SO.S nm/m whereas at the octanol-water interne it is only 8.8 nm/m. Reduction of inter dal tension in the latter case points to the orientation of octanol hydroxyl groups toward water, in other words to the structure and polarity of the interfadal layer. Because of such an orientation, the stimulus for adsorption of other asymmetric molecules on the interface is decreased. A similar pattern is typical of the homologous series of lower attcy] acrylates at the interface with water the carbonyl groups of their asymmetrical molecules are oriented toward water this orientation is more eSective the higher the polarization of the carbonyl, i.e the smaller the alkyl. Interfadal tension decreases in the same order from 27.2 nm/m for hexyl acrylate (Yeliseyeva et at, 1978) to 8 nm/m for methyl acrylate (datum from our laboratory by A, Vasilenko). 

Woven reinforcement material constructed is by interlacing fibers, yarns, or filaments to form such fabric patterns as basket, plain, harness, satin, leno weaves, scrim, etc. These different weaving patterns are used to provide different processing and/or directional properties. There are filling threads that represent threads in the so-called machine direction warp threads represent those in the transverse direction or at 90° to the filling threads. 

Woven geotextiles. A woven fabric consists of two sets of orthogonally interlaced filaments or staple-fibre yams. The weave design or pattern is determined by the manner in which yams or filaments are interlaced. Filaments or yams placed in the longitudinal and transverse directions are known as warp and weft, respectively. Monofilament and slit woven geotextiles are anticipated to be thinner in comparison to multifilament, spun, and fibrillated woven geotextiles. 

Woven fabrics are constructed by interlacing warp and weft yarns, fibres or filaments in a variety of patterns to form fabric styles such as plain, twill, satin, unidirectional and others. Woven fabrics are usually lighter than woven rovings, have less crimp and may achieve volume fractions of over 50% depending on the method of composite compaction. 

This weave is a version of plain weave in which occasional warp yarns, at regular intervals and usually several yarns apart, interlace every two or more fibers (Figure 21.10). A similar pattern occurs in the weft direction to give a fabric with increased thickness, a rougher surface and additional porosity.
