Study Notes
What is Knitting?
- Knitting transforms soft yarn into loops that intermesh, creating knitted fabric.
- Knitting yarn, known as hosiery yarn, has a twist multiplier (TM) of around 2, while weaving yarn has a TM of 3 to 6.
- The interlooping process forms loops linked to adjacent loops, done manually with needles or via high-speed commercial knitting machines.
Knitted Vs. Woven Fabrics
- Knitting has a shorter fabric formation route and faster production rates compared to weaving.
- Knitted fabrics are preferred where stretch is needed, making them versatile for various applications.
Knitted Structure – Needle Loop
- One loop is the basic repeating unit in knitted fabric, analogous to the interlacement point in woven fabric.
- Circular knitting produces tubular cloth, with diameters ranging from 8" to 60".
- Circular weft knitting is faster than flat knitting due to continual needle movement and space efficiency.
Warp Knitting
- In warp knitting, multiple threads are collected in a beam similar to weaving and then processed into knitted fabric.
- Warp loops are made vertically from warp threads, allowing high-speed production, though design limitations exist.
- Warp knitting machines occupy more space than weft knitting machines.
Bearded Needles
- Invented by William Lee in 1589, bearded needles are simple, cheap, and easy to manufacture.
- The knitting cycle involves yarn laying, loop formation, landing, bridge formation, and linking-up through intermeshing.
Latch Needles
- More expensive to produce than bearded needles, latch needles utilize a tongue to catch yarn for bridge formation, completing interlooping.
Pitch & Machine Gauge
- Pitch refers to the distance between consecutive needles, influencing the machine gauge (number of needles in a reference length).
- A specific pitch accommodates particular yarn counts, impacting wales per unit length and knitted fabric properties such as appearance and weight.
Basic Knitted Structures
- Four basic knitted structures can be formed using the stitch:
- Plain knitted structure
- Rib knitted structure
- Purl knitted structure
- Interlock knitted structure
- These are primarily associated with weft knits but can also appear in warp knits.
Patterning Elements
- Various techniques enhance knitted fabric designs beyond basic structures, including:
- Using different types of stitches
- Tuck loops/stitches
- Float loops/stitches
- Inlaid yarn
Characteristics of Knitted Fabrics
- Knitted fabrics are elastic and stretchable in both directions but have limited design capabilities compared to woven fabrics.
- They are produced faster than woven fabrics, though handling and processing can be challenging.
- Dyeing is feasible, but printing techniques are limited with knitted fabrics.
