Weave – it is one of the oldest human inventions. In ancient times, people without a loom, weaving fabric by hand. With the development of weaving people, for beautiful designs, were to unite in one several types of fabric weaves. Quick Reference Dictionary of Weaving – is the order of overlapping warp threads weft. Weave – it is one of the main indicators of its structure.

Tools weave in the weaving industry join the warp and weft and woven fabric are – fabrics and textiles. Use two strands are intertwined system of mutually perpendicular. The basis is called threads, running along the fabric, weft – the threads are located across the horizontal. Way to connect these threads determines the type of weave. A plain weave, this most ancient weave the fabric fibers is – plain (it is call – taffeta) weave. This is the simplest and most common way to weave.

Produce a plain weave cotton fabrics, cotton prints, calico, linen dresses and fabrics, virtually all of the linen tissue, and many fabrics from natural silk and chemical fiber. Less commonly, plain weave used for making woolen cloth. Plain weave – a basic and accurate alternate weft yarns in a ratio of 1:1. In this case, if the first warp thread left on the surface, the second weft thread is closed, etc. Of all existing plain weaves, the smallest differ rapport: the two strands of the basis and the two strands of a duck. Each thread of the story is interwoven with each weft thread through one. This weave provides excellent fusion of tissue structure and, consequently, most of its strength. Plain weave fabrics are characterized by flat matt surface and the same facial appearance and seamy sides. Fabric goes way, because the warp and weft are distributed equally on both sides. In plain weave the increase on the basis of density leads to contraction of fibers in the vertical direction, the weft – the horizontal. Because of this, the cells formed by weaving, are no longer symmetrical and elongated in one direction or another. At significant difference in linear density of weft yarn and the main fabric in plain weave are longitudinal or transverse ribs, there is a rep effect. Thin filaments are bent around the thick and cover them. Therefore, the thick filaments are located within the tissue, and thin – on the surface. This structure allows even plain weave fabric surface to create a system of filaments. If you apply high-thread twist on fabric formed crapy effect, the surface becomes 'grainy'.

With different approaches to estimating the number of homes to buy the spread of digital indicators that lead analysts in their reports too large. Representatives of conservative realtor companies, based on experience communication with customers, believe that the apartments, who buy for resale, not more than 10%.

"The exclusion of simultaneous market entry as large volumes residential area of the collapse in prices is inevitable ", – noted by Professor Sternik. This dramatic scenario could be realized in the autumn of 2008, when came the global financial crisis. "The situation began to change not in favor of investors Apartments: construction has slowed, prices are pushed down and the real estate market went into a lethargic sleep, even the percentage of apartment per day has decreased, "- noticed by experts. If at the time, as selling an apartment, even with 25% – 30% discount percentage, and invest in securities or financial device, homeowners could disrupt a good sum.
