A new technical innovation in the field of zippers will help prevent zippers from shrinking or arching on coming in contact with steam irons-SBS Zipper
Zipper shrinkage or arching is a common phenomenon that affects zippers when garments to which they are attached are steam ironed. The common technical challenge is caused on account of uneven shrinkage of the cloth and the zipper sewed on to it. Researchers have been trying to work out a way to avoid zipper arching for a long time and a technological breakthrough has finally been achieved after repeated efforts.
The expert team from China Textile Academy Haixi Branch collaborated with Jinjang Municipal Government as well as research and development teams of various zipper manufacturing companies including SBS Zipper to develop the groundbreaking innovation that combats zipper arching. Industry experts dealing in various fields such as the textile sector, fibre industry, inspection sector, dyeing and finishing industry and machinery industry worked together with technical personnel from various zipper manufacturing firms to come up with solutions. Key manufacturing technologies as well as the raw materials used for making zippers were also thoroughly examined on-site to figure out the changes required to put an end to the arching phenomenon.
The research team finally found a solution that had the potential to help avoid zipper shrinkages when steam ironing clothes with zippers. The researchers developed polyester filaments, which are especially meant to be used in industries along with a new machine for making zipper tapes. These innovative discoveries led to the improvement in the technologies that are commonly used in the process of manufacturing zippers. The modifications in the production process proved to be a groundbreaking solution to stop zippers from arching.
In order to ensure that the new solution does work, the finished zippers created using the modified production process went through some tests at SBS Zipper's quality inspection centre and none of these new finished zippers arched. Besides reducing shrinkage and arching, zippers made of the modified technology can also help manufacturers deal with uneven dyeing of zipper tapes.
The technical innovation is expected to help Chinese zipper manufacturers to improve the overall quality of zippers to meet international standards. It is expected to improve the competitiveness of Chinese zippers and gain a larger market share across the globe. Chinese zipper manufacturers can also increase the market share in middle and high-end markets by using the new and improved zippers.
Alternative methods to avoid arching
While a technical innovation has been developed to stop zippers from arching, here are some alternative methods that can be used for avoiding shrinkage. These include:-
Placing a cloth on the zipper to prevent the iron from coming in direct contact with it
Closing the zipper and ironing before sewing to avoid zipper arching
Testing the zipper for arching due to high temperature steam before it is sewn
Avoiding direct ironing of electroplated or painted sliders to prevent lacquer or paint from peeling of
