The warp knitted interlining is a kind of Fusible Lining, and some people also say it two way stretch interfacing or tricot interfacing. It is made of warp knitted fabric as basic fabric and coated with glue powder. In general, warp yarns are crocheted into each other in weft direction. This kind of structure makes warp knitted fabric soft and elastic.The characteristics and purposes of warp knitted interlining are as follows.The organization of the interweave of the warp yarn is the method of filling in the weft insertion, which is low cost and high efficiency.
When you are making bags or craft projects, in order to solve the problem that the ordinary fabric is too soft and not enough stiff, ususally we have to attach a layer of fusible interlining or cotton on the back of cloth. But wrong ironing method could lead to adhesion stripping, cloth surface bubbling and other problems.So how can we iron on the fusible fleece alternative smoothly and bonding firmly? You must correctly grasp the three elements of temperature, pressure and time.Hot melt adhesive has its melting point, low temperature will not melt or completely melted, and high temperature can cause loss of viscosity.
Generally, the ironing temperature of fusible interfacing should be controlled between 120℃ ~ 150℃.The pressure of pressing is determined according to the thickness of fabric, the pressure of thin material should not be heavy, otherwise, it will result in glue seeping, Conversely, you can push the iron a little bit heavier on thicker fabric.Ironing time usually takes 5 ~ 8 seconds, if the time is too short, glue melt too late, but long time can cause hot melt glue to penetrate or sublimate.The above three elements also interact with each other. If the ironing temperature is high, the pressure and time can be reduced appropriately and the temperature is low, so it should increase the pressure and lengthen the ironing time.
The tricot interfacing needn’t go through resin finishing so it doesn’t contain formaldehyde. Because the technical process is short, there is little pollution during processing, it can be called environmental protection fusible interfacing.The base cloth of warp knitted interfacing is polyester filament yarn or viscose yarn. The warp direction is smooth and the weft direction has the good elasticity, better flexibility and adapt to elastic fabrics.The excellent characteristics of warp knitted fabrics make it possible to meet the needs of different textures and styles from light to heavy weight. Fully adapted to the various kinds of fabrics and clothing requirements for the adhesive lining.
