Unit 4 - Yarn numbering systems/designation of netting yarn

4.4.Calculation of Resultant tex
The final product and netting yarn may be designated by the resultant density indicated by symbol “R” to be put before the numerical value. Thus R tex means the mass in gm per kilometer of the final product. Size or linear density of twine and ropes are designated by resultant tex (R-tex). It is roughly 10-15 percent more than the combined tex value of the constituent yarns in the finished product. Example for calculation to be included
