Clever Uses of Zippers

  • Unsmooth opening and closing of a slider

    Unsmooth opening and closing of a slider

    The gearing of the elements can be damaged by forcing a slider that does not open or close smoothly. Apply paraffin or the lubricating spray "FastenerMate" to the front side and back of the elements and move the slider up and down several times to work in the lubricant and make the slider work smoothly.

  • Loss of elements

    Loss of elements

    Trying to forcibly close the zipper of an overfilled bag will cause an excess load on the elements. This stress may cause the element to slip out from the tape. This is a fatal problem with a zipper, so the zipper should be closed only after bringing the two element’s sides near each other so that the slider can move more easily.

  • Slider caught in cloth

    Slider caught in cloth

    The slider may catch on thread or cloth when opened or closed. Attempting to free the slider by force will only worsen the problem. Pull the slider back, removing the trapped thread or cloth. When the slider bites deeply into the cloth, do not force back but work back gently. When sewing zippers on garments, take care to avoid the possibility of the zipper getting caught.

  • Putting on or removing clothing

    Putting on or removing clothing

    Clothing should be put on or taken off only after completely opening a zipper. When closing the zipper, the slider will move smoothly if the hook or the top button is fastened beforehand. If the slider is left midway, excessive stress is placed on the elements, bottom stop or the slider itself, and may cause damage. The same attention given to boots, gloves and accessories which have a zipper will keep problems which have a zipper will keep problems to a minimum.

  • Proper ironing with appropriate heat depending on the material

    Proper ironing with appropriate heat depending on the material

    Using the proper heat for the material being ironed is not limited to clothing but is also applicable to zippers. Zippers can be kept durable and beautiful by considering the material of which they are made and ironing with the proper heat. A zipper should always be closed, before ironing, the slider fixed in the proper position and the zipper covered with a piece of cloth regardless of what material it is.

    Elements or sliders may be altered by direct ironing.

  • Suitable method of Cleaning

    Suitable method of Cleaning

    A zipper should be closed and the slider fixed before cleaning. Left open, the tip of the slider may damage the fabric or the tape may become stretched or may shrink. Strong alkaline detergents or chlorine bleaching agents used to remove oil or stains dissolve paraffin or oily film and must be used with care. If a zipper does not work smoothly after cleaning, and work the slider up and down several times until it works smoothly.
