Costing of Folded Yarn: The cost of folded yarn is the sum of the cost of the component threads required and the cost of folding. The quantity of component threads required includes also waste made during the process of folding. This may or may not be significant. Here, we will discuss costing of folded yarns…
The weight of all textile materials varies with the variations in the relative humidity of the surrounding atmosphere in which they are kept. The variations in the weight of different textiles are different. Therefore, the normal practice in the trade is to have the conditioned weight of textiles as the basis of the purchase or…
The calculations involved in determining the average counts in the tex system are much simpler than those of the indirect systems. This is because it is a direct system and the length and weight units are in the metric system. In this article, we will discuss average count calculation in tex system with different examples….
Regain: Regain is estimated from the warp length on a sample cloth. The usual procedure for a grey cloth is to cut the cloth of a convenient length. Then a warp thread is taken out from the cloth and straightened out without unduly stretching it. The length of the thread is then measured and from…
Weft Calculation: During weft calculation in weaving, the following weft calculation formulas and examples in weaving, will be found useful for determining various particulars required in practice. They have all been derived from the fundamental formula, Count = Number of hanks per lb. Different Formulas of Weft Calculation in Weaving 1. Width of warp in…
Efficiency: Efficiency depends on the amount of time lost due to loom stoppages. Less the production loss due to loom stoppages more is the efficiency. In general, the factors on which production depends are also responsible for efficiency. In this article, we will discuss a calculation of loom and weaving shed efficiency in weaving. Efficiency,…
