The warp of the fabric means the lengthwise threads in the fabric. The weft is the horizontal weavers of the fabric.
Weft refers to the threads that run horizontally across the fabric during the weaving process. It is interlaced with the warp threads, which run vertically, to create the fabric structure. The weft threads are inserted over and under the warp threads to create different patterns and textures in the fabric.
The direction for warp is the thread that goes the length of the fabric
Warp count is calculated by determining the number of warp yarns per unit length of fabric, typically measured in ends per inch (EPI). To find the warp count, you can take a sample of the fabric, count the number of warp threads in a one-inch section, and then multiply by the length of the sample to find the total count. For example, if there are 20 warp threads in one inch, the warp count would be 20. This measurement helps in understanding the fabric's density and strength.
The strings on a loom are called warp and weft. The warp refers to the vertical threads that are stretched taut on the loom, while the weft consists of the horizontal threads that are woven through the warp to create the fabric. Together, these elements form the basis of weaving.
The term cloth generally refers to woven fabric that is formed with a warp and the weft, threads running side to side and up to down. Knitted fabric is formed by a series of interlocking loops and it is more flexible or stretches more than woven fabric.

In woven fabric, the horizontal yarns are called the "weft" or "filling" yarns. These yarns run across the width of the fabric and are woven over and under the vertical yarns, known as the "warp." The interplay between the warp and weft creates the fabric's structure and design.
Liseré - Term which refers to a specific type of fabric construction involving a supplementary warp. This supplementary warp, usually multi-colored, can be used to add color and detail in selected areas on the face of the fabric. Where the liseré effect is not seen on the face of the fabric, it is hidden along the back as loosely tacked "floats." Liseré effects are in some ways similar to a tissue pick, however liseré occurs in the warp direction. Most classic liseré designs are stripes, frequently used on wing-back chairs or in formal settings. http://www.regalfabrics.com/learnabout/glossary.htm#L
For Warp Weight, (5315*reed space*EPI*110)/(9000*1000*warp Count) Kgs/100 mtr. For weft weight (5315*reed space*PPI*103)/(9000*1000*weft Count) Kgs/100 mtr. Add both you will get Fabric weight in Kgs for 100 mtr. Here 5 % is warp crimp and 5 % is warp Shrink. 3 % is weft crimp. If you want gms/mtr square i.e GSM then Divide the fabric weight by width of fabric in mtrs.
Yarn count "warp 40s Ne" refers to the thickness of the yarn used in the warp threads of woven fabric, measured in the "English cotton count" system (Ne). The "40s" indicates that there are 40 hanks of yarn per pound, with each hank being 840 yards long, making it a relatively fine yarn. This count is commonly used in textiles for fabrics that require a balance of strength and softness, such as shirts or lightweight garments. The designation specifically highlights its application in the warp direction, which is crucial for the fabric's structure and durability.
Nobody knows, because so far, there is no such thing as warp drive, and the fabric of space is an almost meaningless phrase that's used mainly to talk about Physics to people who don't understand much of it.
It was so hot that the plastic cover began to warp. A spacecraft equipped with a warp drive may travel at velocities greater than that of light by many orders of magnitude The star ship Enterprise can do a maximum speed of warp ten. Each individual warp thread in a fabric is called a warp end.
