The present invention discloses a kind of production process for a fully covered leather sheath product, which comprises the following steps of: determining peripheral dimensions of leather such as the length and width according to the size of the product, and coating the leather with an adhesive; putting the shell of a product to be covered into the upper die of a mold, placing the trimmed leather into the lower die of the mold, and positioning it by a positioning post; heating the above-mentioned leather placed in the lower die of the mold; closing the upper die and the lower die immediately after the heating treatment is complete; opening the mold until the lamination is complete, taking out the product from the mold and fitting it with a fixture for the stretching folding treatment; heating the product along with the fixture to bond the leather with the interior of the product shell; and pressing it along with the fixture after heating; taking the pressed product out of the fixture and cutting excessive leather, attaching an inner lining material of the same dimensions after the excessive leather is cut, and pressing the inner lining material for bonding. The objective of the present invention is to provide a production process for the fully covered leather sheath product, which has high production efficiency and can improve the overall product design effect.

The present invention provides a preparation method of PET environmental protection flooring, which facilitates preliminary mixing and plasticization of raw materials while preventing over-plasticization through coordinating a high-speed mixer and a low-speed mixer, thereby ensuring uniform mixing of the raw materials. Besides, a roller press is used to pr-bond a wear-resistant layer and a decorative film layer while base patterns are is embossed on a substrate layer, thus to achieve rapid molding, bonding, and surface pattern decoration of the three layers, thereby improving production efficiency. The present invention further provides a PET environmental protection flooring, which replaces traditional PVC materials with polyethylene terephthalate for reducing potential risks to human health and the environment. Through the design of multi-layer structure, the wear resistance, decorativeness and structural stability of the floor can be enhanced, thus to prolong the service life of the flooring.
