The industrial Revolution of the late eighteenth and the nineteenth centuries symbolized the arrival of the machine age and advanced the button industry. To achieve mass production of buttons, the factory improved mechanically to increase productivity and cut production cost. During the late nineteen century, the button industry began to use new synthetic that allowed unheard of versatility in color and design in the mass production. After the Second World War, mechanization has become the standard production process in the button industry to cope with the advent of mass consumption in garment. The use of plastic buttons provides the low-cost material for the mass-manufactured process.
There are two types of plastic materials: thermosetting and thermoplastic. Thermosetting substances, such as polyester, urea and epoxy, can be moulded when heated, but the reaction is accompanied by a chemical change, so the material is permanently hardened and heat-resistant thereafter. Thermoplastic substances, such as nylon, acrylic and ABS can be reheated and reformed. The following is a brief introduction to the production process of plastic buttons, including polyester button, urea button and nylon/ABS button.
