Knitted fabric is a textile that results from knitting, the process of inter-looping of yarns or inter-meshing of loops. Its properties are distinct from woven fabric in that it is more flexible and can be more readily constructed into smaller pieces, making it ideal for socks and hats. Knitting is a method by which yarn is manipulated to create a textile or fabric; it’s used in many types of garments. Knitting may be done by hand or by machine. Knitting creates stitches: loops of yarn in a row, either flat or in the round (tubular). There are usually many active stitches on the knitting needle at one time. Knitted fabric consists of a number of consecutive rows of connected loops that intermesh with the next and previous rows. As each row is formed, each newly created loop is pulled through one or more loops from the prior row and placed on the gaining needle so that the loops from the prior row can be pulled off the other needle without unraveling.

  2. To know about machine maintenance of knitted machine.
  3. To know about which machine are used in knitting process for make a knitted fabric.
  4. To know about the layout plan of a knitting production.

Layout description:
The entrance to the lab is along the east side. Yarn packages are located in the creel holder. Use of air compressor to remove dust from the yarn. Then on the right side of the entrance is a single, double jersey circular knit machine. Where single jersey machine uses one set of needles and its needle bed is cylinder &dial type. On the left side there will be a lab in charge who will take care of the total lab. There is a store room next door where final products can be stored. And in one serial flat type knitting machine is installed.

Adopting the 4 track cams seal design and equipped with knit cams, tuck cams and MissCams. High precision central raising and falling System can adjust the fabric weight conveniently and quickly. The special design of the feeding yarn carrier makes the option of Lycra more proficient. Featuring an ergonomic design, the additional middle feeding yarn transfer ring makes it easy for personnel to monitor and carry yarn, without the machine touching the operator’s body; at the same time, the yarn carrying system is freer and steadier, satisfying the demand of machine operating and knitting at high speeds.

  • Machine Gauges: 10-36g
  • No. Of feeders: 32f-96/Inch
  • Speed: 15-30RPM

The cams on the lower and upper dials of this machine feature a closed-track design with cams of knit, tuck and miss. The yarn feeder can be adjusted independently allowing knitting of elastic double jersey fiber by installing an additional Lycra attachment. Also comes equipped with varying types of cylinder, easy and quick to transfer, enabling this machine to meet the never-ending demands of the knitting market.

Interlock knit fabric is used in all sorts of elastic garments, such as T-Shirts, tops and sportswear. It is relatively simple to use, but be careful not to stretch the fabric while sewing. Interlock knit fabric are usually used for the production of T-Shirts, Polo and dresses.

  1. Raschel machines used latch needles together with a latch wire or blade.
  2. Raschel machines have a gauge expressed in needles per two inches (5cm) so that for example, a 36 gauge Raschel will have 18 needles per inch.
  3. Their chain links are usually numbered in even numbers 0, 2, 4, 6, 8 etc., generally with two links per course.
  4. Raschel sinkers only perform the function of holding down the loops whilst the needles rise.
  5. Raschel sinkers are not joined together by a lead across their ends nearest to the needle bar so they can move away towards the back of the machine for the rest of the knitting cycle.
  6. The needle trick-plate verge acts as a fabric support ledge and knock-over surface.
  7. The fabric is drawn downwards from the needles almost parallel to the needle bar at an angle of 120 to 160 degrees by a series of take-down rollers.
  8. The warp beams are arranged above the needle bar centered over the rocker shaft so that warp sheets pass down to the guide bars on either side of it.
  9. The beams are placed above the machine so it is accessible at the front for fabric inspection and at the back for mechanical attention to the knitting elements.
