RMC jeans brand does not use the modern projectile looms, only the old-style shuttle looms which are by far the best and the only old selvedge denim production machines to use and so the story begins.
Simply put, this means that in the weaving process, the thread goes back and forth across as a continuous thread, rather than as a separate thread for each cross weave. Therefore, the fabric is more resilient, while the denim side lined with a clean edge is known as the selvedge. Modern yarns are woven with a different edge to the original.
The traditional fabric of the loom is narrow, from 28 inches to 34 inches; an ordinary size pair of jeans takes about three yards of fabric. To maximize production by manufacturers and so that the fabric has been used to the edge of the cloth side seam with a straight outside, when the cuff of the jeans is turned up you can see the two selvedge edges where the denim is sewn together (some designs can be seen hidden in the coin pocket).
The selvedge seam line colour is usually white with red lines but in earlier manufacturing there was white outside with green lines, yellow lines or more different colours all used in the selvedge edge.
In the originals this difference made it easy to distinguish between the different companies factory cloth fabric. In the original style of the jeans they can from the selvedge edge confirm the distinction.
In today's market the Japanese selvedge denim production is considered the best as it is the rarest. Historically, the U.S. denim was considered the best. However, because the weaving machines were only 30 inches wide they became obsolete. In 1950 when the U.S. manufacturer of denim jeans saw a surge in demand for products they searched for other faster, more beneficial and cheap ways to produce denim fabric. They abandoned the traditional shuttle looms and used projectile looms, a more modern production accounting for 60 inch wide fabric (or sometimes wider) and their profits grew. Manufacturers then replaced real indigo dye with synthetic dyes and began pre-washing all the fabric to control shrinkage and distortion. The lack of a by-product of these changes the selvedge edge denim character.
After the 1980s, Japan's economy bubble burst and took off, many Japanese companies realised there was a market space for traditional jeans. They started in the United States buying the old style shuttle looms, no longer used in the USA and began to re-design distinctive American jeans. In the Japanese apparel company, the "senior Cowboy" craze began to implement a number of visionary companies, but also deliberately introduced the old selvedge jeans and real indigo cloth dyeing. These ancient shuttle looms produced denim lines so natural and irregular, and this unique cloth has also increased the variety of body styles and age. The traditional indigo dye for denim and the dyeing method can also be reproduced. Indigo is dissolved in heated vats and the cotton is dipped several times to build up a dark colour, with airing between each dip, this allows the textile to oxidize and thus fix the colour. The soaking and oxidizing steps are repeated over and over until the final desired colour has been produced.
The old original jean production technology is copied at each stage, including the chain-type line of sewing techniques which is given great care and attention and gives the seams a very high quality and robust finish. This requires a special sewing machine. Again, in the past 40 years, no manufacturer has been producing these special sewing machines. And for a long time the primary users of these machines are the most superior denim manufacturers. They use (union special) "Union Special" brand sewing machines, which are the "Rolls Royce" of the U.S. sewing machine, from the 1950s to the modern day no other brand of sewing machine can be a substitute.
In the production of old types of jeans there must be a lot of technical input and also detailed description of this unique old denim fabric, from cotton to weaving, dyeing and sewing, to create a superior quality, a necessary condition for any jeans brand.
In general the only changes in faded dark blue jeans are through the use of real indigo dye. These details will allow users knowledge of the real authenticity of old denim. Step by step the denim becomes perfected by continuous wear and the natural fabric reduction leaves a unique natural fade, impossible to do under artificial reproduction.
RMC brand having learnt from the history of this old cowboy jean has used and increased the fabric technology and its unique design which enhances the natural changes. In owning and wearing a pair of selvedge jeans people will have a very personal experience and nothing else in the world can give you this same experience.
