Tennis tips
1, There are many production processes of tennis and high requirements for personnel and equipment. Even so, the air pressure of the products produced in the same batch still has a certain range of fluctuations, so there will always be a customer to report receiving the same bag of balls that have not been opened, and there will be different air pressure after opening. This is more likely to happen in bulk balls.
2This kind of pressure protects the air pressure inside the tennis ball. In this way, the pressure attenuation of the tennis ball becomes much smaller before the lid is opened.
3No pressure ball: this kind of tennis is supported by the gallbladder. The pressure inside the ball is the same as the normal atmospheric pressure. Therefore, the elasticity of the ball comes from the gallbladder instead of the pressure inside the gallbladder.
Products are as follows:
Match ball (pressure, no pressure), training ball (pressure, no pressure), soft tennis, children's tennis, short tennis, sticky ball, color tennis, key chain tennis, pet ball(A zebra,Leopard grain etc.), rubber foam ball, rubber hollow ball, rubber ring, furniture/Tennis ball covers
And balls of various shapes,Including the rod,pentagram,The circle,prismatic,square,Such as football and can be produced according to customer's sample processing and requirements!!!!!!!!!
The surface of the ball is not only printableThe logoCan be used in different colors of woolen wrap, ball can also have fragrance, can shine, can play holes, can wear cotton rope and so on
Because the price by wool, flexibility, bladder and other factors decided, price needs to discuss in detail!
What is chemical fibre:
Fiber made from natural or synthetic polymers. According to different sources of raw materials, it can be divided into synthetic fibers with natural polymers as raw materials and synthetic fibers with synthetic polymers as raw materials. The preparation of chemical fibers usually starts with the spinning melt or solution made of natural or synthetic polymer or inorganic materials, and then through filtration and measurement, the spinning head (plate) is extruded into liquid thin stream and then solidified into fiber. At this time, the fiber is called primary fiber, which has poor mechanical properties and must go through a series of post-processing procedures to meet the requirements of textile processing and use. The post-processing is mainly aimed at stretching and heat setting of the fiber to improve the mechanical properties and dimensional stability of the fiber. Stretching is the orientation of macromolecules or structural elements in primary fibers along the fiber axis. The thermal setting mainly relaxes the internal stress in the fiber. Post-processing of wet spinning fiber also includes washing, oiling, drying and other processes. When spinning a filament, it can be wound into a barrel through the above process. The coiling, cutting and packing process must be added when spinning short fibers.
How to identify genuine wool:There are many methods to identify fiber, which can be divided into two categories. One is more intuitive sensory discrimination, and the other is the use of various fibers with different physical and chemical properties to conduct certain tests to achieve the purpose of identification. The commonly used methods include combustion, microscopic identification and bulk solution.(1)Sensory discrimination. This method does not require the use of any articles or equipment, according to*Own intuition, long - term work experience, according to the feel of the fabric and suede to identify. Due to its unique wool-like characteristics, the acrylic fiber can be difficult to distinguish. But as long as careful observation, distinction comparison, there are differences. Intuitively, wool products are softer and more elastic than heavy, with a softer color,The curl of wool is greater than that of chemical fiber woollen, and usually the anti-pilling property of wool is better than chemical fiber woollen
(2) combustion method. Wool products, when burning, smoke bubble while burning, accompanied by the smell of burning hair, ashes, shiny black must be brittle block. When burning, the acrylic products melt and burn slowly at the same time. The flame is white, bright and strong, slightly black smoke, fishy smell, white and round, crisp and fragile. The polyamide fiber product melts and burns slowly while burning slightly white smoke. The flame is small and blue with celery flavor.
