Most weft-knit fabrics have stripes in the width direction because it is more economical to produce these fabrics in this manner. The knitting of weft knits involves yarn being fed into the knitting machine, and the knitting taking place from side to side (or in a circular direction) across the width.
Which direction has the most stretch in a weft knit?
The crosswise loops are called courses. They form a row of loops that run across the fabric. Usually the greatest stretch in a knit fabric is in the crosswise direction. However, it is always important to test or check the stretch in a knit before purchasing.
What is weft knitting structure?
Weft knitting is a knitted piece of fabric where the stitches run from left to right horizontally across the fabric. It is usually knitted with one piece of yarn, and can be made either by hand or using a knitting machine. … The knitting machine was invented to speed up the manufacturing process of knitted products.
Which direction is weft?
The warp direction refers to the threads that run the length of the fabric. This is also known as the machine direction because it’s the direction the threads run on the loom. … The fill, or weft, refers to the yarns that are pulled and inserted perpendicularly to the warp yarns across the width of the fabric.
Which direction does the weft yarn travel when weaving fabric?
Woven fabrics are produced on a loom by interlocking yarns lying in a vertical (warp) and a horizontal (weft) direction. Weft yarns are woven over and under warp yarns, and where the weft yarns loop back to form an edge that doesn’t fray , it is called the selvedge.
Do warp or weft knits have more stretch?
Produced in a large variety of weights in a wide range of fiber types, warp knits are run-resistant and don’t ravel. With a few exceptions, weft knits have moderate to great amounts of crosswise stretch and some lengthwise stretch. Some jerseys, however, have little or no crosswise or lengthwise stretch.
Which has more stretch warp or weft?
The warp threads are typically stronger, as they have to run the entire length of a bolt of fabric. Fabrics with warp and weft threads have the most stretch when pulled diagonally, or on the bias.
What are the advantages of weft knit fabrics?
WEFT KNITTED FABRIC
It is the most common form of knitting used because of its simplicity. Advantages: Weft knitted fabric is very elastic, stretchable and comfortable to wear. It is warm to wear, i.e. a good insulator. It does not fray easily and is very cost-efficient.
What is the difference between warp knitting and weft knitting?
Warp knitting differs from weft knitting, basically in that each needle loops has its own thread. … In warp knitting the needles produce parallel rows of loops simultaneously that are interlocked in a zigzag pattern, while in weft knitting the needles produces loops in the widthwise direction of the fabric.
Is the weft horizontal?
Warp refers to the vertical lines on a woven cloth, while weft refers to the horizontal lines. To weave cloth, the warp is pulled tightly on the loom, creating vertical lines that guide the weft over and under.
Which way do stripes run on fabric?
When upholstering, it generally looks best to run a patterned or striped fabric from top to bottom and from back to front. Imagine upholstering a sofa. It would look best for the stripes to have a vertical orientation, like soldiers standing in a row. Most upholstery fabrics are 54 inches wide.
What is weft in fabric?
Definition of weft
1a : a filling thread or yarn in weaving. b : yarn used for the weft. 2 : web, fabric also : an article of woven fabric.
What is one way you can tell the difference between the warp and weft direction in a woven fabric?
In checks, if you find one colour with odd numbers of threads, it is warp. Then it is easy to determine warps as parallel yarns with selvedge is warp. And yarns those are perpendicular to the selvedge are weft or filling yarn.
What is the difference between weft and woof?
is that weft is (weaving) the horizontal threads that are interlaced through the warp in a woven fabric or weft can be (obsolete) something cast away; a waif while woof is the set of yarns placed crosswise in a loom, interlaced with the warp, carried by the shuttle or woof can be the sound a dog makes when barking.
