Abstract
Official abstract text for this publication.
The present disclosure is relates to a TPU ball structure and a manufacturing method thereof. The TPU ball structure includes a ball bladder layer, a yarn layer and a surface layer. The ball bladder layer is made of TPU material. The yarn layer is made of TPU material, and the yarn layer is disposed to cover the ball bladder layer. The surface layer is made of TPU material, and the surface layer is disposed to cover the yarn layer. The above layers of the TPU ball structure are made of TPU material to satisfy a requirement for environmental protection, and are recyclable. There is no need to use adhesive to adhere the above layers of the TPU ball structure. Therefore, the peeling strength between the layers of the TPU ball structure can be increased so that the whole peeling strength of the TPU ball structure can be increased.
First claim
Opening claim text (preview).
What is claimed is: 1. A TPU ball structure, comprising: a ball bladder layer, including a thermoplastic polyurethane (TPU) long fiber, wherein the TPU long fiber has a 200-500 den fineness and a 5-15 g/d tenacity; a yarn layer, made of a TPU material and disposed to cover the ball bladder layer; and a surface layer, made of a TPU material and disposed to cover the yarn layer; wherein the surface layer comprises an outer surface layer and a latex layer; wherein the latex layer comprises a foamed latex layer and an unfoamed latex layer, the foamed latex layer is disposed on the unfoamed latex layer, and the outer surface layer is disposed on the foamed latex layer; wherein the thickness composite ratio of the outer surface layer to the foamed latex layer to the unfoamed latex layer is 1:8:1. 2. The TPU ball structure of claim 1 , wherein the TPU yarn is wound to cover the ball bladder layer. 3. The TPU ball structure of claim 1 , wherein the yarn layer is made of TPU winding yarn or TPU hot melt yarn.
