Pure cotton canvas density calculation units in the metric system, refers to a square inch of Canon of weft arrange the root of the number. The size of the density, directly affects the appearance of the fabric, feel, thickness, strength, folding resistance, air permeability, abrasion resistance and thermal physical and mechanical indexes such as performance, at the same time he also relates to the size of the product cost and production efficiency. Pure cotton canvas measurement method has the following two kinds:
1.direct count method
(1) method is according with cloth or fabric density analysis mirror to complete. Scale length is 5 cm of fabric density analysis of mirror, on the analysis of the lens below, a strip of glass engraved with a red line, based on the analysis of the fabric density, move the camera, the glass on the red line and scale on the red alignment between two root yarn, at the same time as a starting point, moving the camera while count yarn, until 5 cm scale line for this;
(2) the number of yarn multiplied by 2, that is, to 10 cm fabric density values.
2.this method is suitable for the density, the rules of the yarn count small fabric of the organization. First of all, through the analysis of the warp yarn fabric and its organization cycle number circular weft count (organization), and then multiplied by the number of organization cycle in 10 cm, income is the product of the weft yarn density.
The above methods to determine the density of pure cotton canvas has been determined, welcome for technical communication and discussion, field trips can contact with the company if necessary.
