how do you find the warp and weft of a fabric?

Question

specifically for fleece fabric; also would fleece even have a warp and a weft as it is synthetic fabric?

Answer 1

Warp and weft are terms for woven fabrics -- most fleece is a knit, and has wales and courses instead. Compare the fabric in your jeans (woven in a twill pattern) to a t-shirt and you'll see the differences.

Answer 2

Some fleece may not have a warp and weft; not because it's synthetic but because it is a knit. The type of fiber has little bearing on whether the fabric has a warp or weft, it has to do with the process of turning the fiber into a fabric. There are three types of fabrics, woven with warp and weft and already explained; knitted, which has threads going one way only and looped together to form fabric, and felted fabrics which have neither warp nor weft.



Knit fabrics are made with one long yarn that goes back and forth along a knitting frame. In commercial production knits are made on long frames comprised of thousand of tiny little hooks that look like latchet hooks, as the yarn goes back and forth along the frame it is drawn through the loops on the hooks as the hooks move in and out, opening and closing, making the rows of the knit. In this there isn't really a warp or weft. For cutting we refer to the stretch properties, the greater stretch goes across the body and this is usually (but not always) across the width of the fabric, while the length is usually more stable. Knits can also be made on tubular knitters and cut after knitting. A few rows will be unravelled to form selvages. Many polar-tech fleeces are made on tubular machines, cut to form selvages, then the surface receives several processes to raise up the fleece surface.

Warp And Weft Of Fabric

Answer 4

"In weaving, weft or woof is the yarn which is drawn under and over parallel warp yarns to create a fabric. In North America, it is sometimes referred to as the "fill" or the "filling yarn", and in India, it is referred to as "baana", which is derived from another hindi word "bun na" or "bunai" which means making with threads or strings, as is done in cane weaving and other forms of primitive weaving techniques.



The weft is a thread or yarn of spun fibre. The original fibre was wool, flax or cotton. Nowadays, many synthetic fibers are used in weaving. Because the weft does not have to be stretched in the way that the warp is, it can generally be less strong.



The weft is threaded through the warp using a shuttle."



There is also a picture showing which threads are warp and which are weft if you go to the web address I included below :)

Answer 5

Dictionary: To arrange (strands of yarn or thread) so that they run lengthwise in weaving.



Tho with fleece, I think there is only "stretchy" and "non-stretchy"
