Everything begins with the material’s treatment

may, 2018
Wool is considered one of the most resistant materials and it has an advantage over its maintenance because it isn´t a fiber in which dirt accumulation is biased. The material comes to our company with a unique whiteness, thus allowing the dyeing and absorption of all colors and tones.

Mohair (or fine wool) is one of the oldest natural fibers. Coming from the hair of the Goat Angora, this material has in its composition the hair of the goat and silk. This material, like wool, is easily dyed but also has several colors without dyes thanks to the tone of the animal's hair (white, brown and black).

In dyeing, wool comes in untreated yarn and is 100% natural. This is where the magic begins. The material is washed in the “arm machine” with hot water and specific product to eliminate the animal fat and to purify the wool. This machine is automatic, however, we still do the washing by hand in a metal tank with the same use of product.

It is in the laboratory that we create all the colors. With the dyeing department of Ferreira de Sá, we offer a varied range of colors to satisfy the needs of our customers without creating barriers. In these 72 years, we have created more than 318 colors in wool and fine wool that are present in the boxes of pompoms. Each color has its recipe: dye junction, way to reach and dry. This process is one of the company's best kept secrets and undoubtedly an essential step in creating a special and unique rug.

Yarn Colour
After the dye is created, the yarn is dyed in the "cabinet" machine. It is in this step that the material moves from its natural color to the color that the customer wants. Each color has its dyeing time and the process is carried out with water vapor and specific products. The wool can be dyed as many times as necessary without losing the quality of the yarn.

Drying is the last step of dyeing. After reaching the right color, the yarn is led to the dryer. This process is defined depending on the type of color and different colors are not mixed in the same drying. The material is then transported to the centrifuge where excess water is withdrawn. Finally, the wool is stored in the drying oven.

After finishing the dyeing process, the wool is transported to the winders, where it will be transformed into a reel or roller. Finally, they are stored in their stocks and ready to use.
