the fabric is enhanced as is its value a secondary fiber yarn is fed together with the very fine cotton yarn in an interlock knitting machine so as to create double knit fabric loops formed by the very fine non elastic yarn cotton on both the external and internal surfaces of the fabric while the loops created by the secondary fiber preferably elastane also known as spandex are arranged on both inner surfaces of the fabric the secondary fiber yarn most preferably comprises elastane fiber yarn other fiber yarns such as elaspan lycra u00ae or a similar type fiber yarn can also be used as the secondary fiber the linear mass density of the secondary fiber is preferably between about 17 u2014 about 44 decitex and is most preferably between about 22 decitex u2014 about decitex the very fine cotton yarn is fed in parallel with the secondary yarn in an interlock knitting machine this interlock knitting process allows the secondary fiber yarn to form its loops on the inner side of the double jersey fabric and the very fine cotton yarn to form its loops on the external surfaces of the double jersey fabric the yarn feeding tension should be adjusted to make stable conditions so that knit fabric can be knitted with constantly adjusted yarn feeding tension the very fine cotton yarn and secondary fiber yarn are tightly knitted together using an interlock knitting machine in a preferred embodiment the interlock machine is a 24 gauge interlock knitting machine in a preferred embodiment the knitting machine is run smoothly at between about 20 rpm and about 25 rpm due to the yarn strength and so that there is no.
