Sewing the items of dense materials is the task causing a lot of troubles. Such fabrics have tendency to wrinkle, shift, and crumple under the metal presser foot, the element that retains and straightens the material parts to be sewn together.
This occurs because of high friction coefficient between the fabric and the presser foot surface. The presser element doesn’t slide well along the material, and as a result the latter starts puckering and shifting.
The sewing shops making the items of natural and artificial leather (for instance, shops sewing items for car interior) remark that fabric rumpling leads to significant fall of works productivity, and to loss of the finished items’ quality.
To make sew masters’ work easier, and to improve productivity of the sewing process, the presser feet with the Teflon coating are used. Their base is made of polymer material, and after that a Teflon layer is applied onto the item.
However, application of such elements is related with a number of difficulties. The Teflon presser feet have a short service term, and the expensive components have to be often replaced. The anti-friction layer on such parts has tendency to damages, and cannot be restored. Besides, the parts assortment is limited, it’s not so easy to find a suitable Teflon presser foot for each sewing machine model. The users frequently have to seek for the components on the foreign websites.
As more effective and available alternative for the Teflon presser feet, MODENGY 1009 anti-friction solid-film coating is used. It is applied onto the metal presser feet surface.
This coating forms a smooth dray layer on the parts that reduces friction coefficient of the mated surfaces, makes sliding of the presser foot along the leather or other dense material easier, prevents forming creases, crumpling, and shifting.
The coating is applied onto the prepared parts surface by the standard painting methods, and polymerizes at heating in a kiln.
The strong layer formed on the presser foot surface after the product gets cured is resistant to mechanical damages, has no tendency to scuffing. MODENGY 1009 needs no refreshing for the entire service lifetime of the sewing machine pressing element.
Use of the anti-friction solid-film coating enables to minimize number of rejects at sewing items of complicated materials, to make sewing masters’ work easier, and to increase sewing rate.
