The Structure of the Zipper...

Tape

The zipper tapes are generally knot with 300 denye 100 % Polyester thread in narrow knitting machines. The tapes are knot according to the type and characteristics of the zipper to be produced, and with sizes shown in the table below. During the knitting, the piping which provides that the metal and bone zipper tapes cling to the gears side is knot together. The nylon tapes are knot without piping. They are later sown with the gears. The tapes can be knot on Cotton and Mixture as required. The piping are generally of 100 percent Polyester. They can be of cotton as required. The tapes can be on any design (Fish Back, Sand Design) as the related company requires acconding to its own standard. In the narrow knitting machines like these, tapes with vertical stripped designs can also be knot using color threads. Moreover, as required, tapes with ladder-mender can be knot for the Fabric producers. Designs, images, reflectors and foils can be printed over the tapes with hot transfer. The zipper tapes are knot with raw threads unless is required otherwise. The knot threads are painted at 130 C in the high temperature and high pressure (HT) system painting machines according to order quantity and color. They are fixed, too. The painted tapes are dried at 120-130 C. And they are prepared for usage.

Cursors

They are produced by Zamak. They are produced with a variety of sizes according to different types of zippers. They are colored with covering or epoxy according to the type o fthe zipper.

Matters to be concerned in Zipper Selection

  1. In selecting a zipper, be careful about the garment weight and thickness. Do not select thin type zipper for thick garments.
  2. Seek special lock in the zippers of baby and child wear.
  3. In order to make the correct selection, ask for zipper performance tests, quality documents and ecotext certificate from your customer representative.
  4. Do not select metal oxide zipper for the light color wears.
  5. Prefer zippers which are environment friendly and which do not harm the human health.
  6. Do not use secret zippers in stretch wears.


Matters to be concerned in Zipper Ordering

  1. Information is given during the ordering for the zippers to be sown to the contrast colors. Precaution is taken against color speciality and color flowing.
  2. In order to fix the sought color at the zipper, at least a 5X5 cm garment sample should be sent. Moreover, the colors can also be selected from the color scale.
  3. The difference between the length of the zipper stated at the label and the length of the product should not exceed +/- 3 mm, or the proportion of this difference to the product length should not exceed +/- 1,5 %.
  4. Ir orders, up to 7 % over products are delivered. The zippers with bottom that are shorter than 14 cm are priced over 14 cm while the separate ones that are shorter than 30 cm are priced over 30 cm.
  5. For the bone zippers, three different paints are used. For this reason, prefer lesser orders and silver or oxide gears for samples.
  6. The production of the zippers are done for normal usage conditions and washing at home condition. If the zipper is to be handled with a special manner and/or to be subject to chemical washing, state this situation during the ordering.
  7. Information should be given during the ordering for the colors to be looked at under conditions other than the daylight. Since the wavelengths of the daylight lamp and fleuresant lamp are different, different colors may be percepted over the same garment. Unless there is a special request, the colors are adjusted according to the daylight.
  8. The zipper tapes are 100 % Polyester. It should be noted that there shall be tone variances because of the mixing with cotton, light surface and melange garments.
  9. The color OK request should be informed at the ordering stage.
  10. If you order secret zipper, you are recommended to state 2 cm zipper length.
  11. If the zipper tape subject to the order is less than 1,5 kg, there may be tone variance in the colors.


Matters to be concerned in Zipper Usage

  1. The zippers are completely closed, cursor is locked, the product is turned inside out at the products that are subject to washing operation.
  2. For washing operations, 30-50 C temperatures are recommended.
  3. The zippers to wait for long should be waited in their package and under none-damp conditions.
  4. The product to which zipper is sown should be packaged after being subject to vapor ironing and press operation and cooling.
  5. At the separate zippers, the mutual tapes should not be mixed to each other. (There may be difference in tones, designs and lengths.)
  6. Chemical materials should not be used in the washing of the painted cursors. The product should be turned inside out and the temperature should not exceed 40 C and there should be sufficient product in the washing tank.
  7. Leave sufficient distance between the garment and the zipper where the tape can easily operate. The zippers should be sown to the flexible garments without stretching. Note that the pedal of the sewing machine should not press the cursor. Also ensure that the press iron is not extremely hit on the zipper.
  8. Do not touch the needle to the metal parts of the zipper while sewing the zipper to the garment. This needle can be broken. The needle that is pressed between the stops may cause injuries.
  9. While sewing the zipper in the sewing machine, do not cut the zipper tape; otherwise, the zipper tape shall be torn down since the tapes are knitted garment.
  10. A thread or a garment may intervene the cursor while opening or closing the zipper, and forcing the cursor in order to continue opening or closing may increase the problem. The cursor should be pulled back. The intervening thread or garment is put out. The zipper is sown to the product with great care such that it does not push the cursor.
  11. Parafin type material is applied to the gears of the zipper in order that the zipper is easily opened and closed. While ironing, put a piece of garment or paper over the parts touching to the zipper in order to prevent the garment from becoming stained.
  12. Put on and take off your wears after completely opening or closing their zippers, respectively. Otherwise, the gears, bottom stop or cursor can be overloaded, thus the zipper might be damaged.
  13. If the zipper is operating stretch after washing, apply candle or soap over its gears.
  14. While sewing the secret zipper to the product, you should exactly fix the special secret zipper sewing apparatus to your sewing machine. Otherwise, you may face problems.
  15. Take care so that the solutions and plushes do not harm the gears in the production of boots, shoes and bags.
