2. Moulded Zippers These zippers of the teeth are produced by injection moulding using high grade engineering plastic materials. 3. Metal Zippers The teeth of the zippers are stamped out of metal strips such as brass, aluminum, bronze or nickel silver alloys. The constructions of metal zippers are shown in Figure 13.6. Fig. 13.6 Construction of a typical stamped Metal Teeth (Source: www.ansun.com) 4. Innovative Zippers Due to the specific performances of textile and clothing, requirement of specialty zippers are also necessary to meet the functional performance of the garements. As a result, innovations were made to produce novel types of zippers. Few of the innovative zippers are given below. • Flame-resistant zippers • Airtight …show more content…

Weaving of textile fabric – The cotton or some other blended yarn in warp and weft are used for weaving a narrow fabric with a high speed needle loom t produce a woven edge braiding. Before the complete edge braiding of zipper must be through weaving, cutting and winding processes. Zipper chain forming – The resin (if it is polyester) is fed into the injection moulding machine to form a zigzag line. Zipper slide head and end stopper – metal or aluminium alloy is fed into the die casting machine to produce a slider and end stopper with required size and shapes. Sawing and Fitting – The textile fabric and zipper chain are attached together by means of sawing machine. Then the slider, top and bottom stopper of zipper are fitted and …show more content…

It could be manufactured from an extensive variety of materials, such as natural materials like antler, bone, horn, vegetable ivory, ivory, shell, and wood; or synthetics like celluloid, bakelite, glass, metal and plastic. Hard plastic is the most common material for manufacturing of buttons (Carr & Latham 2006). 13.1.2.1 Types of buttons • Shank buttons have a small ring or a bar with a hole known as shank projecting from the back of the button, through which sewing thread is sewn to join the button as shown in Figure
