Thread count
Count is a numerical value, which express the coarseness or fineness (diameter) of the yarn and also indicate the relationship between length and weight (the mass per unit length or the length per unit mass) of that yarn. Therefore, the concept of yarn count has been introduced which specifies a certain ratio of length to weight. Thread count is expressed by warp and weft yarn. Thread count is very important for GSM and cover factor. But the GSM and cover factor are also depend on the thread density.

From the Table-1 and Figure-1; we have seen that the highest warp count is 40 Ne of Plain and the lowest warp count is 8 Ne (16+16) of Boxy. Also we see that the highest weft count is 40 Ne of Plain and the lowest weft count is 5 Ne (10+10) of Ottoman. Ne (English Count) is the indirect system. In theoretically higher Ne must be finer than lower Ne. So all the results we have collected regarding thread count comply with the theory.

Thread density
Thread density is the number of warp and weft threads per inch of woven fabric. Thread density is denoted by EPI and PPI. Thread density is very important for GSM and cover factor but the GSM and cover factor also depend on the thread count.

From the Table-2 and Figure-2; we have seen that the EPI is always greater than PPI. The highest EPI is 154 of Bedford cord and the lowest EPI is 100 of ottoman. Also we see that the highest PPI is 85 of Dobby and the lowest PPI is 48 of 2/1 RHT. In theoretically EPI must be greater than PPI. EPI is greater than PPI in our result. So all the results we have found in thread density comply with the theoretical concept.
