Various Terms Used in Knitting Technology

Course: Horizontal row of loops produced by adjacent needles in knitting cycle is called the course of the fabric. A course is a predominately horizontal raw of needle loops produced by adjacent needles during the same knitting cycle. Wales: Vertical column of loops produced by same needle in knitting cycle is called the wales of the fabric. Number of vertical columns of loop of knitted fabrics is called wale. Face Loop: If the legs of new loop are passes over the old loop is called face loop. Back Loop: If the legs of new loop are passes under the old loop is called back loop. Stitch Density: The term stitch density is frequently used in knitting instead of a linear measurement of courses or wales; it is the total number of needles loops in a square area measurement such as...

Variables of Knitting Technology

In flat knitting, the fabric is usually turned after every row. However, in some versions of double knitting with two yarns and double-pointed knitting needles, the fabric may turn after every second row. Knitting Variables  - Yarn Count  - Yarn Twist  - Spinning System  - Yarn Ply  - Stitch Length  - Yarn Tension  - Take Down Tension  - Machine Gauge ...

Classification of Knitting

Knitting is two types: 1. Warp Knitting 2. Weft Knitting Weft Knitting is again two types: 1. Circular Knitting 2. Flat Knitting Circular Knitting is again two types: 1. Single Jersey 2. Double Jersey Warp and Weft Knitting There are two major varieties of knitting: weft knitting and warp knitting. In the more common weft knitting, the Wales are perpendicular to the course of the yarn. In warp knitting, the wales and courses run roughly parallel. In weft knitting, the entire fabric may be produced from a single yarn, by adding stitches to each wale in turn, moving across the fabric as in a raster scan. By contrast, in warp knitting, one yarn is required for every wale. Since a typical piece of knitted fabric may have hundreds...

Maintenance of Knitting Machine

Knitting m/c needs to be maintained regularly for getting excellent performance of m/c and also maintain the proper quality of production. Maintenance for circular and flat bed knitting m/c is different. There needed separate maintenance for different types of knitting machines. Maintenance of Circular Knitting Machine: 1. Check out the m/c before starting the m/c. 2. Check out the yarn type, fabric type before starting the m/c. 3. Check out the fabric which is producing by the m/c. 4. Check out the m/c motor, belt, panel card. 5. Check out the m/c wheel. 6. Check out; is the roller pulling the produced fabric regularly? 7. Check out the fabric detector and needle detector. 8. Check the knot catcher. 9. If needle or sinker breaks, then submit the broken needle and take new one. 10. Remove...

4 point system for detecting or calculating fabric faults

There need international standard quality inspection section in all knitting industry where the fabrics will be inspected by inspection m/c for detecting the faults and remark the fabric roll as grade A, B, C and R (Reject). They are using 4 point system for detecting the fabric faults. There point and grade of fabric inspection are as below: 1. Up to 01 to 15 Point = “A” Class 2. Up to 16 to 20 Point = “B” Class 3. Up to 21 to 30 Point = “C” Class 4. More than  30 Point = “R” Class (R=Reject) N.B: Any Hole = 4 Point Actual Grade Formula: Points*3302/Length (meter)*Width (inch) Calculation Points/100 SQ. M = Total Points*39.37*100/Roll Length (m)*Actual Width (inch) ...
