line of similar strength!
sewing thread factory direct wholesale generally: 602 lines used for thin fabric, such as the summer wear silk, georgette;     603 and 402 line can be basically universal, sewing line is the most common, ordinary fabrics can be used, such as cotton, linen, polyester, viscose and other commonly used fabric;     403 lines for a thick fabrics, such as do business fabric;     202 and 203 line can also be called a cowboy line, line is thick, high strength, used for sewing denim, bags etc..

　　举例：用平 Car line (line 301 step step) sewing knitted polyester elastic coat, a stitch density D=9, double fabric thickness T=2.2mm, 70/3 shares to sewing, the total length of the use of this stitch each dress for 21.3m, try to seek for each piece of clothes with line amount is how much?
　　解：根据计算公式L=1.571+0.07854DT+0.0124D√Tt得
　　L=(1.570+0.07854X9X2.2+0.0124X9X5.036)X21.3=78.555（米）
