Example 1: A red (or corresponding color card number) combed polyester/cotton blended corn dyed yarn with a linear density of 14.8 tex, composed of 65% polyester and 35% cotton, and intended for knitting, shall be labeled as: Red (or corresponding color card number) JT/C 65/35 14.8 tex K. Note 1: JT/C is the code for combed polyester/cotton blended yarn. Example 2: A black (or corresponding color card number) corn dyed yarn with a linear density of 14.8 tex, made of carded cotton and intended for weaving, shall be labeled as: Black (or corresponding color card number) C 14.8 tex W. Note 2: C is the code for carded cotton.
