What are the terms for weaving?
- Selvage: The woven edge of a fabric. …
- Shed: The opening created on a loom where the weft passes.
- Tabby: Plain weave and ground weave for a pattern weave. …
- Sett (also epi / ‘ends per inch’): The number of warp threads per inch.
- Threading (drawing in): Drawing the warp threads through the eyes of the heddles.
Which shrinks more warp or weft?
These are the reasons for shrinkage:
In case of a fabric, the warp yarns are under much strain due to interlacement than the weft yarns. Hence when a fabric is allowed to shrink, the warp yarn shrinkage will be more than weft yarns.
What is picks per inch in weaving?
Picks per inch (or p.p.i.) is the number of weft threads per inch of woven fabric. A pick is a single weft thread, hence the term. In general, the higher the picks per inch, the finer the fabric is.
How do you calculate picks per inch?
If it’s plain weave, twill, or lace weaves, this is usually the same number as warp threads per inch. Then you multiply that number (picks per inch) times the number of inches you‘ll be weaving the piece times the width of the weaving plus about 10% (for example, by 11 inches for something 10 inches wide).
Which way do filling yarns run?
The lengthwise yarns (sometimes called the warp) run parallel to the selvage edge of the fabric. They are usually more tightly twisted, stronger, and more stable than the crosswise yarns. The crosswise yarns (sometimes called the woof, weft, or filling) are perpendicular, or at right angles to the selvage.
How do you calculate the end?
The basic formula for calculating ending inventory is: Beginning inventory + net purchases – COGS = ending inventory. Your beginning inventory is the last period’s ending inventory. The net purchases are the items you’ve bought and added to your inventory count.
How do you calculate ends per inch in weaving?
E.P.I. are ends per inch and is what your warp sett will be. It can be determined by wrapping around a ruler just to touch, don’t smoosh together. Count the wraps and divide by 2 for plain weave, divide by 2/3 for twill because you need more warps per inch to weave a balanced twill.
What is course per inch?
The horizontal row of loops or stitches running across the width of a knitted fabric corresponding to course of a knitted fabric. Numbers of course in an inch in knitted fabric is called course per inch (CPI).
How do you calculate a weave?
To calculate the amount of weft, you need to know warp width, the number of picks per inch, and the length of the weaving. I usually add ten percent to that number for weft take-up. (So for an 8″ wide warp woven at 20 picks per inch for 65″: 8″ x 20 x 65″ = 10,400″ divided by 36″/yd = 288 yd plus 10% = 317 yd.
