Technical Field

The invention relates to the field of plastic toys, in particular to a preparation method of a pet toy combining PVC and oxford.

Background

The pet toy is a toy for playing with a pet, and is different from the conventional toy. The conventional toy is a toy for a young child or a female child, a male child, for removing a sense of empty or for eliminating time. The pet toy is a parent-child type toy based on the pet as a human partnership, and the purpose of the toy is to enable human beings and their babies to really interact with each other, so that the human beings and their babies can more greatly communicate and interact with each other in emotion.

At present, most of pet toys on the market are made of rubber, TPR (thermoplastic rubber), TPU (thermoplastic polyurethane), materials and products which are too high in production cost, heavy in development cost, low in yield and high in selling price are not favorable for development and updating of the pet toys.
