Suitability

INVIYA® I-400 is quite adaptable to different makes of Circular Knitting machine available in the market with various kinds of attachments (tensioning device) and feeders

  • INVIYA® is elongated before feeding to plaiting zone at the needles as per required draft. Required draft can be calculated by simply dividing the speed of hard yarn (cotton) by unwinding speed of INVIYA® and can be adjusted accordingly.
  • INVIYA® tension is an effect of draft. The draft/ tension in INVIYA® yarn will depend upon the denier used and its content in the fabric. With a fix combination of hard yarn, count and INVIYA® denier the content can be varied in a range of 20% (e.g. 4 – 5% content).
  • INVIYA® can run at an unwinding speed upto 90 m/min without any hindrances and compromise on working speed of knitting machine.
  • INVIYA® can be stretched up to 6 times of its original length however, the stretch percentage in the knitted fabric can be varied over a wide range both in length and width wise. This can be controlled by fabric engineering. Load and unload power of INVIYA® is balanced which is appropriate for required stretch and recovery property of finished fabric. In addition to stretch property of INVIYA®, it has higher and appropriate modulus to maintain the required pressure of fabric on body while used over a long period.
  • INVIYA® has balanced property in terms of resistance to heat.
  • With INVIYA®, the stretch and recovery power of the fabric is well retained even after repeated washes/ processes.
