Knitted fabric for producing indigo-dyed cotton denim jeans

Abstract

A fabrics for producing jeans, in particular, a knitted fabric for producing indigo-dyed cotton denim jeans, which is suitable for producing four-season type jeans, is provided. Here, raw yarn obtained by dyeing 100% cotton yarn with natural indigo dyestuffs is knitted by a ring-type knitting machine, to thus provide a knitted fabric for producing four-season type indigo-dyed cotton denim jeans which possesses color tones such as blue and black peculiar to jeans as well as possesses functions such as flexibility, ventilation, warmth-keeping performance, and elasticity, and which can be also put on in midsummer and midwinter. Cotton denim jeans are not knitted by a cotton knitting machine which discriminates warp and weft to thus cause skin friction and creases, but are knitted with the knitted fabric by a ring-type knitting machine without discrimination of warp and weft. Accordingly, the knitted fabric possesses functions of flexibility, ventilation, warmth-keeping performance, and elasticity, according to textual features of the knitted fabrics. Also, raw yarn before knitting is colored with blue or black which is a natural indigo dye, to thereby possess a color peculiar to the jeans and impose no burden of friction with the skin on a wearer. Also, although the four-season type indigo-dyed cotton denim jeans closely contact any portion of the wearer's body, they can be put on even in midsummer and midwinter due to a soft feeling to the touch. To realize this, a knitted fabric for producing cotton denim jeans is produced by the steps of: obtaining raw yarn by dyeing 100% cotton yarn with natural indigo dyestuffs of blue or black; directly inserting rubber yarn which has spandex features into the raw yarn; and simultaneously knitting the rubber-yarn inserted raw yarn by a ring-type knitting machine, to thus provide the knitted fabric for producing indigo-dyed cotton denim jeans which possesses spandex features.

What is claimed is:  
     
         1 . A knitted fabric for producing cotton denim jeans, the knitted fabric produced by the steps of: 
 obtaining raw yarn by dyeing or immersing 100% cotton yarn with or into natural indigo sol-type dyestuffs of blue or black;    directly inserting rubber yarn which has spandex features into the raw yarn; and    simultaneously knitting the rubber-yarn inserted raw yarn by a ring-type knitting machine, to thus provide the knitted fabric for producing indigo-dyed cotton denim jeans which possesses spandex features, and peculiar functions of preventing creases and friction with the skin.
