      First, we were to each dye 6 wool samples in increasingly dark shades of a single dye (the CTC uses Lanaset dyes on protein fibres like wool and silk). Next was to join up with a partner to create a gradient of your two dye colours on silk and nylon. Finally, we created a triangular gradient of three colours on cotton, using a dye called Novacron. loop pile carpets, shading effects of color patterning can appear as panelling down the length of the carpet. Both phasing and panelling are an accepted part of the design and in no way affects the carpet’s performance. All carpets will change in appearance over time, particularly in areas of high foot traffic. Good quality pad will extend aFile Size: 1MB.

    The need for more water brings the need for more energy to heat the water, and more chemistry to treat the water and carpet fibers adequately for the dyeing process. A beck produces one lb dyeload in about three hours, giving a lb/hr output for dyed carpet. This work presents an ecofriendly method for dyeing synthetic fabrics with natural dyes using UV/ozone pretreatment to activate fiber and improve dyeability of polyester and nylon. Fabrics are pretreated with UV/ozone for different periods of time ranged from 5 min to min. Effect of pretreatment on surface morphology was studied by scanning electron microscope (SEM).Cited by:

    Acid dyes - anionic dyes applied to fibers such as silk, wool, nylon and modified acrylic fibers under acidic conditions; Basic dyes - usually water soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Azo dyes - addition of the 2 components to make the azo dye directly on or within the fibre. Colors can increase or decrease the value of an object. Dyes are a water based variety of colors. Dyes have played a vital role in human history. In the book, "Treason's Peace - German Dyes and American Dupes" by Howard Watson Ambruster, the dye industry is directly cited as the primary underlying cause of both WWI and WWII.

Dyeing methods have not changed much with time. Basically water is used to clean, dye and apply auxiliary chemicals to the fabrics, and also to rinse the treated fibers or fabrics. The dyeing process involves three steps: preparation, dyeing and finishing, as follows:Cited by: Godfrey Hirst Carpets has been recognized for saving more than kL of water per day by recycling water used in the carpet dyeing process.

This represents a per cent water reduction for its carpet dyeing operations, equating to 85ML of water over the course of the year, or around 85 Olympic sized swimming pools.

This method is called carpet dyeing. There are several carpet dyeing methods in use, each producing a unique end result. The first technique, often referred to as Beck, or batch dyeing, involves stitching the ends of the carpet together, and then running the tufted carpet loop through large vats of dye and water for several hours.

We use a huge quantity of water in dyeing section. Textile dyes include acid dyes, used mainly for dyeing wool, silk and nylon and direct or substantive dyes, which have a strong affinity for cellulose fibers.

Mordant dyes require the addition of. less water, chemicals and energy consumption. This reduced the pollution load in the effluent. Proper selection of dyes and chemicals is, therefore, vital to achieve environment-friendly polyester dyeing.

Chemical pre-treatment may be broadly defined as a procedure mainly concerned with the removal of natural as well as added impurities in fabric to a level necessary for good whiteness and absorbency by utilising minimum time, energy and chemicals as well as water.

Waste water heat is recovered and re-used in a heat exchange system, reducting energy throughout our dyeing process.
