Ends per inch (EPI or e.p.i.) is the number of warp threads per inch of woven fabric. … Terms do vary (for instance, in North America, the weft is sometimes referred to as the fill or the filling yarn). Each individual warp thread in a fabric is called a warp end or end.
What is the number of threads per inch in warp or filling?
A term describing the total number of warp and filling yarns that are present in one square inch of fabric. When determining threads per inch, plied yarns count as one yarn.
What is picks per inch?
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.
What term describes the process of interlacing two sets of yarns at right angles to each other?
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting.
What is the fabric sett?
The foundation of any type of weaving is based on the relationship between your warp and your weft. This relationship is complex and comprised of different aspects: warp and weft material and weight and even the spacing of your warp. The spacing of your warp is called your sett.
How do I find the horizontal thread count?
It is worked out by counting the lengthwise (warp) threads, and then the width-wise (weft) threads. Once counted, the amount of weft threads and warp threads are added together to form the thread count. (E.g. a fabric with 100 warp threads and 100 weft threads is said to have a thread count of 200).
What is the number of ends per inch for warp yarns referred to?
Ends per inch (EPI or e.p.i.) is the number of warp threads per inch of woven fabric. In general, the higher the ends per inch, the finer the fabric. … Terms do vary (for instance, in North America, the weft is sometimes referred to as the fill or the filling yarn).
What is GSM formula?
Method: – Cut 5 swatches from the different place of the fabric. … – Multiply the average weight of swatches by 100 to calculate GSM of the sample fabric. (Normally, the area of round GSM cutter is 1/100 square meters.)
How do you count ends and picks?
Step 3: Count number of ends and Picks inside those squares.
In case yarns are thicker and visible with open eyes count numbers of Ends and picks using a needle or a pin. In case, yarns in the fabrics are not visible and not possible to count with open eyes, pull out warp and weft yarns one by one from the cut squares.
What is 40s cotton?
Cotton 40-40 is the heaviest. The weight of 40s count yarn is 1.5 times that of a yarn of 60s count. This is cheaper than both cotton 60-60 and cotton 60-40. Durability of clothes is a major issue and cotton 40-40 is the most durable fabric among all.
How many sets of yarns are used to make knits?
knitted fabrics are produced by set of connected loops from a series of yarns. Woven fabrics are produced by the interlacing two types of threads. One set of yarn is used in this method. Two sets of yarn is used for this method.
What is done by interlacing two sets of yarn?
Weaving, production of fabric by interlacing two sets of yarns so that they cross each other, normally at right angles, usually accomplished with a hand- or power-operated loom. … In weaving, lengthwise yarns are called warp; crosswise yarns are called weft, or filling.
How do you calculate sett?
To guesstimate a weaving sett from wraps-per-inch, divide the wraps-per-inch by two to get an approximate sett for plain weave. By reducing the number of yarns in an inch by half, you leave room for the weft to go over and under the warp.
How is WPI calculated?
To calculate the wraps per inch (WPI), simply wrap the yarn around a pencil or knitting needles. Don’t wrap too tightly, just provide the normal slack you would if you were knitting. Wrap the yarn for approximately 3-4” along the pencil/needle. Use a ruler and count the number of wrap per inch.
