Mobile phone factory real shot:

1,  there are many tennis production processes, which have high requirements for personnel and equipment. Even so, the air pressure of products produced in the same batch still has a certain floating range, therefore, guests will always encounter the same bag of balls that have not been unpacked, and there will be different air pressures after opening. This situation is more likely to occur in bulk balls.
2, why should tennis be installed: it is not called vacuum packaging, but high-pressure packaging. This kind of air pressure protects the air pressure in tennis, so before opening the cylinder cover, the air pressure attenuation of tennis is much smaller.
3, non-pressure Ball: this kind of tennis ball is supported by the gall. The air pressure inside the ball is ordinary atmospheric pressure, so the elasticity of this ball comes from bladder of a ball instead of the air pressure inside the gall.

Products are as follows:

official Ball (pressure, no pressure), training ball (pressure, no pressure), soft tennis, children's tennis, short tennis, sticky ball, color tennis, keychain tennis, pet ball( zebra, leopard print, etc.), rubber foam ball, rubber hollow ball, rubber ring, furniture/ table and Chair tennis booties

and balls of different shapes, including sticks, five-pointed star, circle, prismatic, square, rugby, etc. can be processed and produced according to customer samples and requirements.!!!

The ball surface can not only be printed LOGO, can be wrapped with different colors of woolen, the ball can also have fragrance, can shine, can be punched, can wear cotton string, etc.

Because the price is determined by many factors such as Woolen, elasticity, liner, etc., the price needs to be discussed in detail!

What is chemical fiber:

fibers made from natural or synthetic polymer materials. According to different sources of raw materials, it can be divided into artificial fibers with natural polymer materials as raw materials and synthetic fibers with list of synthetic polymers materials as raw materials. The preparation of chemical fibers usually starts with making natural or synthetic polymer substances or inorganic substances into spinning melt or solution, and then through filtration and metering, extruded from spinning head (plate) into liquid stream, then it solidifies into fibers. At this time, the fiber is called primary fiber, and its mechanical properties are very poor. It must go through a series of post-processing procedures to meet the requirements of textile processing and use. Post-processing is mainly aimed at stretching and heat setting the fiber to improve the mechanical properties and dimensional stability of the fiber. Stretching is to make large molecules or structural units in the primary fiber Orient along the fiber axis; Heat setting is mainly to relax the internal stress in the fiber. The post-processing of wet spinning fiber also includes washing, oiling, drying and other processes. When spinning the filament, it can be rolled into a cylinder through the above process; When spinning the staple fiber, it is necessary to add processes such as curling, cutting and packaging.

How to identify true and false wool: there are many methods to identify fibers, which can be summarized into two categories. One is more intuitive sensory identification method, and the other is to use various fibers with different physical and chemical properties to carry out some experiments to achieve the purpose of identification. Combustion method, microscope identification method and volume solution are commonly used.(1) sensory identification. This method does not require any articles or instruments, according * my intuitive, long-term working experience, according to the fabric feel and suede to identify. Because acrylic fiber has unique excellent characteristics like wool, it can make people difficult to distinguish. However, as long as you observe carefully, there are still differences in difference comparison. Intuitively speaking, wool products are relatively soft, elastic, large proportion, soft color, degree of curling of wool is larger than degree of curling of Chemical Fiber Wool, and generally wool has better Pilling resistance than Chemical Fiber Wool

(2) combustion method. Wool products, when burning, smoke and bubbles while burning, accompanied by the smell of burning hair, ash, shiny black must be crisp block. Acrylic fiber products, burning, melting while burning slowly, the flame is white, bright and powerful, slightly black smoke, fishy smell, Gray is white round ball, crisp and fragile. Nylon products, melting while burning slowly, burning a little white smoke, the flame is small blue, with celery fragrance, Jie is light brown hard block, not easy to twist into pieces.
