Boiled wool fabric: The production and benefits of our high-performance material

January 17, 2020

Boiled Wool Fabric

Wool is an impressive, natural material that has great properties from the ground up. Through the boiling process, these properties are further strengthened. The result is a thick, soft, and especially durable fabric - which is ideal for use in our high-quality products.

 

But how is GIESSWEIN boiled wool actually produced?

 

Step 1: Choosing the Yarn

Yarn for boiled wool fabric

In general, boiled wool is made of wool or wool-mixes. The quality of the final boiled wool product thus depends upon the selection of its base materials. In our production process, only the finest, high-quality yarn makes the cut.

 

Step 2: Knitting

Knitting boiled wool production

After the yarn is selected, it’s then knitted. In order to make sure that we don’t get any cramped hands or stiff fingers, our knitting machines do this step for us. Depending on each product’s specific needs, different machines and patterns are used. For our unique “3D Stretch Merino Wool”, we’ve even developed a special knitting technique. This technique increases the flexibility of the Merino wool, which makes for an especially comfortable fabric.

 

Step 3: Boiling

Boiling

Now it’s time for the most delicate part of the process: just like cooking the perfect steak require finesse, our boiling process requires the correct temperature and timing. Now’s when the knitted products are washed in large machines with the supervision of our experienced employees. Through this process, the fabric’s surface is roughened - which results in the forming of countless air chambers. The resulting boiled wool is then much softer, more durable and better at sealing in warmth. During the boiling process, we only use fresh water without any artificial additives. That’s what allows us to reuse up to 90% of the water that we use during our production processes.

 

Step 4: Refining

Refining boiled wool fabric

At the end, the boiled wool must be dried and further worked. There are many different ways in which we carry out our refining process: for example, by steaming the wool, we’re able to refine it into the desired thickness. Our hemming machine, or our “make-the-wool-soft-machine” as we like to call it, leaves the high-quality fabric feeling softer than ever.

 

That’s how we turn high-quality wool into our high-performance boiled wool: the 3D Stretch Merino Wool.

 

The Benefits of Boiled Wool Fabric

The natural properties of wool are further strengthened throughout the boiling process. Through this process, the wool becomes even more:
  • Long-lasting and durable
  • Breathable
  • Wind resistant
  • Dirt- and water-repellant
  • Insulating
  • Wrinkle-free

Throughout our many years of experience, we found a way to produce our fabrics with even higher quality, and yield products that are softer than ever.  The special knitting and boiling techniques that we’ve developed - which makes a fabric we call “3D Stretch Merino Wool” - makes Merino wool even more flexible and comfortable. It’s thanks to processes like this that we’re able to craft products with such high quality and comfort…right here in our facilities in Tyrol, Austria.
