To cater to diverse requirements for more economical products & faster lead times, this technique has emerged. It's basically like the hand-tufting process with a change of using a modified sewing machine to do the tufting.
Depending on the intricacy of the design, these tufting machines are available from single needle to upto 20 needles or even more if required. Also, as it has a motor, the tufter has the freedom to regulate the speed of tufting, and the number of tufts per inch (which are mainly modified stitches). It can be operated by foot pedal or by the control terminal on the machine case.
This technique is useful to produce polyester yarn carpets and bathmats.
