What is the canvas?
The canvas is a simple woven fabric with an even number of threads between the warp and the weft. It is the fabric used for most of the sheets and tablecloths.
The canvas is the basic weave, the simplest because each warp thread is intertwined with each weft thread at each crossing. It is therefore also very robust and resistant; the right side is the same as the reverse and the surface is a bit dull. The canvases can be full and compact, but also open, sparse, depending on the result to be obtained.
The canvas is manufactured with any fiber, but the most widespread use is in linen or cotton linen and in light summer fabrics. Technical characteristics of cotton cloths are the relationship between weft and warp threads. For example, in the "20/24 canvas" the first number expresses the yarn count both in warp and weft (normally it is the same in warp and weft, the canvases are said to be square, unless otherwise specified), the second number indicates the (warp) threads and the weft beats.
The different types of fabrics also differ in their resistance, given by the number of warp and weft threads per centimeter, which can also be in the ratios 27/27, 27/30 and 30/30. In general, the following rule applies: the greater the number of cotton threads, the greater the resistance of the material and the fabric will shrink less during washing, ensuring a high quality of the garment in question. Dalfilo sheets use only 30/30 cotton canvas, the highest in terms of quality and resistance.
If the count of the warp threads is different from that of the weft, the warp thread is usually thinner and more beautiful. A canvas is said to be double twisted when it is made up of twisted threads both in warp and weft.
