More and more people, choose a good time out of the time to fly a kite, but the kite line, strong and fine, kite line fine appearance, extremely flexible, in the wind to play a great power, many people do not know, in fact, The line is mostly twisted fiber as the main material. Twisted fiber not only has excellent flexibility, and can be any dyeing, multi-layer twist can be dyed, can make ordinary kite line, from the monochrome, and kite style any match, become brilliant.
Twisted fiber twisting refers to the two cross-section of the yarn to produce relative rotation, then the yarn in the original parallel to the yarn axis of the fiber tilted into a spiral, the short fiber, the twist is mainly to improve the strength of the yarn , And filament twist can not only improve the strength of the yarn, but also produce three-dimensional effect. The number of yarn twist and the twist and twist of the yarn in the fabric with the appearance and performance of the product have a greater impact.
High strength yarn: refers to the tensile strength can withstand more than 8 grams / Danny yarn, high strength yarn for high tensile requirements of the ribbon. Twist is the yarn twisted, the yarn in a single yarn or yarn in a single yarn showing the tilt direction. Points S twist and Z twist two, S twist = hand twist, Z twist = backhand twist. Any single strand will have twist.
Twist refers to the fiber has a certain strength, elasticity, elongation, gloss, feel and other physical and mechanical properties, must be twisted by changing the yarn, the fiber structure to achieve yarn twist, in fact, the use of cotton yarn cross- Angular displacement, so that the original straight parallel to the fiber and the yarn axis tilt to change the yarn structure, the thickening process in the twisting process gradually shrink from the width of the two sides gradually folded into the center of the yarn to form a twisted triangle, In the twisted triangle, the width and cross section of the sliver changes, from the flat ribbon, gradually into a cylindrical yarn.
The role of fiber twisting:
1
On the length of the yarn. After twisting, the fibers are tilted so that the length of the yarn is shortened to produce twist.
2
On the yarn density and diameter. When the twist coefficient is large, the yarn is dense, the inter-fiber gap is reduced, the density of the yarn is increased, and the diameter is reduced. When the twist factor is increased to a certain extent, the compressibility of the yarn is reduced and the density and the diameter change little, whereas the fiber is slightly thicker due to excessive fiber inclination.
3
Impact on yarn strength. For single yarns, when the twist factor is small, the strength of the yarn increases as the twist coefficient increases; but when the twist factor increases to a certain critical value, the twist factor is increased and the yarn strength decreases. For the strands, the twist factor of the strands is the same as the single yarn in addition to the twist, and the uniform twist can make the fiber uniform.
4
On yarn elongation at break. For the single yarn, the elongation at the spun yarn has increased with the increase of the twist factor in the range of the twist factor. For the strands, the twist elongation increases with the twist factor increase The
5
When the yarn twist coefficient is large, the fiber inclination angle is large, the gloss is poor and the feel is hard.
Fiber twisting not only improves yarn strength, but also changes the fabric style. In the twisting process, the fibers are subjected to tension, elongation deformation occurs, the outer fibers of the yarn are subjected to tension and elongation, and the outer fiber produces centripetal pressure between the inner fibers of the center of the yarn. As the twist increases, many of the physical and mechanical properties of the yarn are changed, the tightness of the yarn increases, the diameter decreases, the strength increases, the feel becomes hard and the gloss changes.
According to the principles of physics, the kite line itself is very fine, when the force on the object, the pressure will be great, the process of line or take the line, and "rope saw wood off" the same reason. If the high-speed movement of the object and the kite line collision, then it will have a strong destructive effect. So, the more the more powerful the kite line is more dangerous.
Experts say that the bite of the kite line, the ability to cut the object similar to the dagger, outdoor kite fly, be sure to stay away from the play of the children, and the best to wear gloves to protect the hand from harm.
