Correct use of the zipper

- Feb 28, 2019-

Reasonable and correct use of the zipper is an important way to improve the service life of the zipper.

Reasonable use includes the meaning of the second layer. First, the matching is appropriate. The zippers of different specifications and different varieties are matched on the appropriate clothing, and the second is the correct sewing and use.

1. Important tips for purchasing a zipper

Because the zipper has different adaptability in different environments and occasions, different specifications have a certain scope of application. The requirements for ordinary zippers and special zippers are different. Therefore, when using zippers, the manufacturers must pay attention to the following problem: 1.1 zipper application object When purchasing the zipper, the purchaser should inform the zipper manufacturer whether the zipper is used on the product or not, and whether there is any special post-processing requirement for the product. If the ordinary washing or the acid enzyme is washed, it is convenient for the zipper manufacturer. The requirements of the supporting products will be adjusted appropriately for the quality and individual requirements of the zipper.

1.2 zipper length and allowable tolerance

The meaning of the length of the zipper is different in different zipper forms. Since the zipper is a flexible fabric, it will have a certain expansion ratio due to the external force. When purchasing the zipper to determine the size, it must be considered.

1.3 Requirements for zipper components

Because different countries and regions have different environmental and ecological requirements for textiles, the methods of inspection are not the same. In particular, the grade requirements for azo, heavy metals, and needles are very different, so in the procurement of zippers. It is best to indicate the country or region where the product is exported, or directly request the zipper component.

1.4 Children's clothing zipper safety tips

In order to ensure the safety of zippering in children's clothing, we must not only control the chemical composition of the zipper products, but also the requirements of the metal fittings. For example, it is recommended to use the injection molding to stop and stop, the metal fittings have no sharp edges, etc., to avoid sharp angles. Injure and scratch the skin of children.

2 .The zipper finished product should be paid attention to during use. 

2.1 The correct selection and use of the slider Different sliders have different functions and should be selected correctly. In the washing process of clothing, some chemical components of the detergent are worried about corrosion. For example, denim is best to use a spring-loaded slider that is resistant to washing. The zipper is washed in the pulled state, and the agitation process is used. The lock puller receives a sudden pull or causes some debris to enter the slider, causing damage to the slider.

2.2 Correct use of zipper accessories

Since the metal upper and lower stops are sharper than the design of the penetrating chain, the sharp parts are inadvertently exposed during the manufacturing and use process, and there are unsafe factors. Therefore, it is recommended that the children's clothing be selected when the zipper is selected. Use the upper and lower stops of the injection molding. The same is true for zippers that include underwear. For the open zipper, be sure to insert the cannula into the bottom end of the socket cavity, insert it into the end, and then pull the slider. If the cannula is not inserted in place, forcibly pull the slider, which is easy to cause the first zipper. The chain element is deformed or displaced, and the two chain elements can not be articulated or the head can not be pulled. Even if it can be pulled, the element can be broken. The insertion of the cannula is not in place and it is easy to cause damage to the insert. The correct way When the slider is not pulled, please pull the slider back and check that the intubation is in place and there will be no problem.

2.3 The problem of discoloration of metal zipper elements 

The chemical nature of copper alloys is a chemical reaction that occurs when acid, alkaline, oxidizing agents or reducing agents are encountered, causing color discoloration. The zipper may change color when the chemical remaining on the fabric chemically reacts with the fastener element, slider or open-end part of the metal zipper. This is reflected in high temperature and high humidity conditions (the sewing product is steam-ironed, sealed and packaged). It is easier to occur in a plastic belt for a long time, etc. This is not a quality problem with the zipper itself. The metal zipper is treated in a protective process, but due to the oxidizing nature of the copper material, even if the protective treatment is sitting well, there is an inevitable occurrence. For example, when a copper zipper is used for leather products or wool products, it turns black due to the oxidation of the metal. This is because the leather products are bleached with chromic acid, tannic acid and wool products during the bleaching process (ammonium sulfite). After that, because the neutralization is incomplete, the residual substances in the product are caused by gaseous substances. In order to prevent the oxidation of the copper alloy, it is necessary to carry out anti-rust treatment, but it will promote discoloration due to the use of a strong treating agent and sealing in a polyethylene packaging bag. The rubber band itself contains sulfides, which tend to cause blackening of the oxidation reaction of the copper material, so it is necessary to avoid the use of rubber bands to bundle metal zippers.

Remind the manufacturers of metal zippers, clothing bags should not be sealed, keep breathable, use moisture-proof paper, anti-wetting agent, the effect will be better.
