Provided are a shoe component pretreatment solution and a pretreatment method using the solution, wherein the shoe component pretreatment solution comprises an acidic compound, a salt compound, an surfactant and water. The present invention involves applying the shoe component pretreatment solution to a rubber sole, thereby shortening the process of the pretreatment step, and avoids the use of any MEK organic solvents and also avoids the generation of suspended particulates caused by grinding, thus eliminating harm to the human body and the environment, and reducing the costs in terms of time and money.

A method of forming a fiber-bound engineered material utilizing carrier screens is provided that imparts an intended characteristic at an intended relative location. Also provided are articles formed of fiber-bound engineered materials manufactured utilizing carrier screens. A fiber layer is placed adjacent at least one carrier screen and entangled with additional fibers in a manner to create a non-uniform engineered material. The lack of uniformity of a fiber-bound engineered material may be accomplished through manipulation of the fibers and/or through fiber binding a scrim. The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections.

A transport apparatus is for conveying a shoe sole, and includes a rail unit divided into process and bridge regions, a delivery device and a transfer device. The delivery device is movable in the process and the bridge regions, and includes a conveyor belt for carrying the shoe sole and to move the shoe sole on the rail unit. The transfer device is located adjacent to the bridge region, and includes a transfer roller assembly and a transfer belt, which surrounds the transfer roller assembly and is drivable by the same for carrying the shoe sole. When the delivery device is in the bridge region, the conveyor belt is adjacent to the transfer belt, and is operable to convey the shoe sole onto the transfer belt.

The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections. Variations in the fibers and/or inclusion of scrim materials prior to entanglement allows for an intended characteristic (e.g., a functional characteristic) at an intended relative location (e.g., a position determined by an article to be formed therefrom).
