PRESENT SITUATION OF DENIM

HOW IS DENIM FABRIC PRODUCED ?
Warp fiber in a definite number of warp filament that is dyed when transferring to beam shaft is tied to beam weaving loom and transformed into raw non-washed fabric by throwing raw fiber from weft yarn. Then they go to treatment and their width is fixed here, they are sanforised against shrinkage and transferred to confection in their original color after they are tightly packed against oxidation.

WHAT ARE THE COLORS IN DENIM FABRIC ?
Color in denim (indigo dyed) fabrics is only dark blue, unfortunately. However, due to the characteristics of the dyestuffs, after the fabric is shipped, crude fabrics for pants can be obtained in confection factories and part washing establishments by subjecting them to processes that transfers them from dark blue to ice blue, homogeneous or non-homogeneous color, authentic, and on which various effects can be created.

WHAT IS THE SITUATION WITH WEAVING BASED FABRICS ?
We can say that weaving fabric sector could not get that much share from denim (indigo) market up to now, unfortunately. In fact, creating denim effects in weaving fabrics is much more exciting and has more variety. However, the reason for not applying this up to now is the difficulty in obtaining fibers in bobbin form. Even if they can be obtained, there are not that many firms having large capacity that can continuously support the establishments, available fibers are in general weaving torsion (with weaving strength and handle), and it is not possible to go above 20 Ne based on fiber producing principles. While the fashion of denim and wear out fabrics in the world markets is so popular, this deficiency is tried to be filled up with piece washing and wear out method of fabrics that are dyed with reactive and sulfur dyestuffs. The reason for this is only to fill up the place of denim fabric. It is well known that denim fabrics are completely those that are based on wear out principle.

In fabric sectors, reactive wear out, sulfur dye wear out and denim fiber must be held at the same concept because a dye that does not wash out as a result of reactive wear out causes deformation, shortage in usage life in fabric since its physical appearance is distorted as a result of force and chemical applications. On the other hand, fabrics on which wear out is applied by sulfur dyestuffs have cancer-causing characteristics. The demand in the market conveys us to productions that we do not want to conduct or that actually should not be approved.

HOW DOES FIBER IN WEAVING BASED FABRICS PREPARED ?
We already talked about technologies used in indigo fiber production, and as it can be seen, it is not quite possible to produce fiber compatible with weaving sector with these technologies. However, they can be used anyway. A difficult and risky process such as taking the used fiber to bobbin after the application of two techniques, such as dying from hank and another one is applied. More importantly, it is necessary to use thick and high twist, hard handle fiber as the fiber number to be obtained.

• In principle, it is certain that it is useful to allocate machine park in textile and weaving establishments where indigo fiber will be used to indigo dyed fiber only. If this is not possible, it will be adequate to take only measures in related establishments.
• Similar to measures we take during we work in the same space for dyed fiber or different raw fibers, the machine tool that will work indigo must be isolated from other machine tools, although not too much. It will be enough to put a curtain around machine for this purpose. This is a measure for spill up around machine. If ventilators are available in weaving machines, it will be useful to direct the air towards locations other than those nearby machines we perform other work, air hauling in weaving halls must be towards air channel under the hall so that there will be no spillage in other machines. In short, the mentioned measures are the same with those measures that must be taken in establishments where raw or white types work together in a hall in which dyed fiber or dyed yarn types work together.
• Indigo dyed fibers have the ability of giving color after dying due to the nature of the dye. Due to this characteristic, desired washing effects form at the end of product washing processes. This situation is a desired and expected situation. In general, color giving will be felt even with hand contact, especially in dark colors. As a result of dying process we developed, the indigo dyed fiber that can be used in all kinds of textile and weaving establishments was working previously with other indigo qualities only in denim establishments. When compared with fibers dyed with conventional systems, color giving is reduced by 50%. The fibers that are dyed with this process that can be used in every type and that can be applied without any problems with the measures we mentioned above will create a new era...
