Double Folding and Sewing machine
The textile industry is known as a global industry. With the development of technology, it is undergoing huge changes. The industry must improve the efficiency of the production process, including cutting, weaving, etc., to adapt to changes in the market. How to efficiently return to the state of tubular cloth for dyeing and finishing of open-width knitted fabrics after heat setting is an important part of improving the efficiency of the knitting industry. Suntech Double Folding and Sewing machine can sew open-width fabrics into tubular fabrics for dyeing and finishing.
The required state of knitted fabrics in the processing process is different, and since lycra is increasingly being used in textile industry, a process of heat fixing of the fabric is required before dyeing. For this reason the raw tubular fabric has to be slit open, heat fixed and then sewn in tubular form again to be dyed. when the knitted fabrics are heat-setting, the fabric need in open width state. In the subsequent dyeing stage, the fabrics need to be in the state of tubular fabrics and then would return to open width fabric. Therefore, in order to reduce the loss of fabrics, Suntech Double Folding and Sewing machine use single-thread sewing. Once the dyeing is finished, the operator just needs to pull the thread and the tubular fabric will come into open width again, which can effectively reduce the waste caused by the secondary damage of the fabric. And there is break thread detecting system, machine will stop automatically when sewing thread breaks, so there will not have problem of loose stitch..jpg)
Knitted fabrics are usually produced by circular knitting machines. Because of the characteristics of its weaving method, the knitted fabrics have tension and curling characteristics. The problem of how to effectively control the fabric tension and curling is a problem that needs to be faced all the time when dealing with knitted fabrics. Only by controlling the tension and curling of the fabric can the fabric be treated to a certain extent without destroying the fabric structure.
How Suntech Double Folding and Sewing machine make sure the edges alignment ?
1.)there is one pneumatic deviation roller at fabric entry, the photo-sensor will detect if the fabric is in middle of machine, and will send signal to move deviation roller up and down to move the fabric in middle of this machine.
2)there is a big centering roller, will make the fabric in center of machine before folding.
3) during folding the fabrics, there would be a pair of edge-alignment raster which will detect these two edges of folded fabrics, when these two edges is not in aligned position, the edge-alignment raster will move left or right to align these two edges.
How Suntech Double Folding and Sewing machine control curled edge of fabric ?
1)There is one group of scroll rollers(two pieces) to open curled edge in fabric inlet.
2)Mechanical uncurling device in front of edge alignment
3)electrical uncurling device and air blowing device before sewing
And Suntech Double Folding and Sewing machine are fast and easily handled and only need one operator, which save labor cost.
