Product Information

In music, a string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano ( piano wire), and members of the violin family. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably. Strings may be "plain" (consisting only of a single material, like catgut, nylon, or steel). "Wound" strings have a "core" of one material, with an overwinding of other materials. This is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility for playability.

SenseBall is the revolutionary football (soccer) training ball implemented in football clubs and academies around the world such as the Belgian FA, AC Milan, Leicester City FC, Rangers FC, Sevilla FC, Real Sociedad, RSC Anderlecht, KRC Genk, RCSC Charleroi, Sporting Kansas City, FC Metz, FC Nantes, Toulouse FC, Willem II, FC Lugano .... Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft or filling. ( Weft or woof is an old English word meaning "that which is woven". [a]) The method in which these threads are inter woven affects the characteristics of the cloth. [12] Thread is a type of yarn used for sewing. Thread is made from a wide variety of materials. The following table lists common materials, a general description and what they are supposed to be good for. If your machine will sew with the thread, any thread can used for just about any purpose. This is very useful for someone who is trying to learn sewing. However, it should be remembered that where a thread is stronger than the material that it is being used to join, if seams are placed under strain the material may tear before the thread breaks. Garments are usually sewn with threads of lesser strength than the fabric so that if stressed the seam will break before the garment. Heavy goods that must withstand considerable stresses such as upholstery, car seating, tarpaulins, tents, and saddlery require very strong threads. Attempting repairs with light weight thread will usually result in rapid failure, though again, using a thread that is stronger than the material being sewn can end up causing rips in that material before the thread itself gives way.The principle of SenseBall is based on the concept of bilateral activity. Thanks to its specific design, online exercise videos and didactical program, a player practicing with SenseBall will make an average of 500,000 touches of the ball in a season.

String was used in prehistoric times to make fire, as part of a drilling tool called the bow drill, which makes fire by friction, as well as fishing lines, nets, clothing, shelter making materials, bow string, sutures, traps, twine, cordage, and countless other uses. [2] Bow drills were used in Mehrgarh between the 4th and 5th millennium BC. Similar drills were found in other parts of the Indus Valley civilization and Iran one millennium later. In Roman times, the same principle also was used widely in drilling for purposes of woodworking [3] and dentistry. [4] Recommended by professional football players, SenseBall is especially aimed at young players between 6 and 20 years of age. Training with SenseBall makes them two-footed and improves their football skills. SenseBall also improves the performance of all sportspeople for whom high-speed and precise leg movements are essential (basketball, tennis, skiing, handball…). Macramé comes from a 13th-century Arabic weavers’ word migramah meaning “fringe”. This refers to the decorative fringes on camels and horses which help, amongst other things, to keep the flies off the animal in the hot desert regions of northern Africa. One of the earliest recorded uses of macramé style knots as decoration appeared in the carvings of the Babylonians and Assyrians. Fringe-like plaiting and braiding adorned the costumes of the time and were captured in their stone statuary.Dooley, William H. (1914), Textiles (Project Gutenberged.), Boston, USA: D.C.
