Description of the invention (2) high elastic racket line structure The research of the method and its manufacturing method and the idea of integration are invented, and the invention is to produce a molten TPE that is mixed between the nylon monofilament bundles, so that it exists between the nylon monofilaments of the core yarn in a uniform and stable control state. Three coating layers such as a TPU and nylon mixed layer, a τρΕ nylon mixed layer, and a TPU layer are sequentially covered thereon to form a racket line body and / ,,,, and Q structure, which can ensure that the racket line has More stable abrasion resistance and elasticity 'in order to achieve excellent industrial applicability and practicability. "Objective of the Invention" Therefore, the main purpose of the present invention is to provide a wearable, highly elastic racket, structure and manufacturing method, It is mainly by melting and melting τρΕ between the bundles of right nylon monofilaments, so that TpE can be uniformly and stably controlled. I exists between the nylon monofilaments that are threads; by this, 俾Can ensure Tight and loose combination, while providing more stable elasticity. The secondary object of the present invention is to provide a wear-resistant highly elastic racket string structure and its manufacturing method, which is to sequentially cover a mixed layer of TPU and nylon outside the core line A TPE and nylon mixture layer and a τρυ layer, and the tpu in the first coating layer has the property of increasing the wear resistance of the racket line, so that the τρυ and nylon mixed layer can increase the strength of the coating interface, and at the same time through the first The two coating layers τρΕ and the nylon mixture layer have better elastic recovery rate and recovery rate after being stressed. The outermost TPU layer has stability and better abrasion resistance, so that the racket line made by this method can have both stability. Abrasion resistance and elasticity, and can be widely used in a variety of rackets.

Please refer to the second figure, which is the racket line of the present invention Schematic diagram of the production process 'It does not have a molding equipment (50)' It includes two pay-off tables (51) (52), two bundles (53) (54), an oven (55), two coating devices (56) (57) and a take-up table (58); when molding, first nylon 6 or nylon 6/66 copolymer nylon monofilament (1 2) from the spool (511) on the take-up table (50) ) —Release all together (please refer to the third picture), and wind it in the positive direction and then bundle it at the concentrator (53) to form a thread structure, and then use molten TPE (ll) to press and fuse to each nylon sheet. A bunch of threads is formed between the filaments (12) as the core (10), and the manufactured core (10) is passed through the first coating device (56) so that the outside can be covered with a TPU and nylon mixture layer ( 2〇), and then pass it through the second pay-off table (52) and the bundler (54), and then wound a nylon monofilament (31) layer in the opposite direction, and then fused with tpe (32) The second coating layer of τρε and nylon mixture layer (30) is formed between each nylon monofilament (31). After the coating is completed, it is dried and cured through an oven (5 5), and then passes through the last coating. After the device (57) is covered with a Tpu layer (40), the forming process of the racket string body (A) can be completed, and then it is rolled up through the take-up table (58). 1 As mentioned above, The abrasion-resistant high-elastic racket string structure and manufacturing method thereof are provided by using molten TPE to mix between the nylon monofilament bundles, so that τρΕ is present in the core thread under a state of uniformity and stable control. Between the monofilaments, three coating layers such as TPU and nylon mixed layer, τρΕ and nylon mixed layer, and TPU layer are sequentially covered thereon, and the method and structure of forming the racket string body can ensure that the long racket string has more Stable abrasion resistance and elasticity, with more than 4 吝 sauce 杳 ΪΒ Λ 山 η V ,, "527200
