Notes on tent zipper

February 19, 2018 BY TRIMS CO.,LIMITED Zippers Knowledge

We often see metal zippers, plastic zippers and nylon zippers on clothing, bags and tents .Zippers for tents usually have higher requirements.Due to the characteristics of tents, special care should be taken when selecting and sewing tent zips. We will share some useful tips to help you make your tent zipper more durable.

Please select the source chain and slider from the same zip supplier. If there is a mismatch between the zipper chain and the slider, the elements at the corners of the tent are likely not to engage perfectly. So in order for the chain and slider to fit each other perfectly, we recommend purchasing from the same zipper manufacturer

If you would like to source differently, please take care both the chain specifications like single side teeth width, double side teeth width and double side teeth thickness when the zip is completely closed, and the slider specifications like the mouth height, mouth width and tape gap should all be in conformity with the industry standard speculated.

It is recommended that you choose a larger zipper size to ensure greater tension and strength, and to ensure greater safety in use. The special properties of tents also require better physical performance of tent zips in comparison with their counterparts in the garment industry, including the slider puller pull-off strength, slider mouth deflection strength, resistance to twist of puller and slider, chain crosswise strength and the resistance to reciprocation.

Generally speaking, 5#/7#/8#/10# nylon zip can be used for tents. However, it is advisable to opt for larger zip sizes like 7# and 8# to accommodate the special characteristics of the sewing technique.

At last, please ensure the alignment of the seam line on the zip tape, and ensure the location of the seam lines aligns on both sides of the tape. Additionally, make sure the seam line aligns on the same side of the tape while sewing the zip.

Great difference in the location of the seam lines on both sides of the tape, and misalignment of the seam line on the same side of the tape when the zip is sewn onto the tent will result in uneven tension applied to the left and right sides of the zip, causing sliding resistance for the slider. When there is excessive resistance along the sliding track of the slider, closing the zip quickly by force would lead to the pressing and deformation of the teeth elements within the inner cavity of the slider, causing the teeth elements to mis-engage.
