Our materials

 

We strive to minimize pollution to the environment at any stages of production. Our goal is to make natural materials accessible to more people and this is our input to maintain ecological balance, thus decrease the negative effect of industry to the environment.

Sheep Wool

Our main material is locally sourced semi-coarse and semi-fine sheep wool. The harsh conditions of the mountains make the local sheep wool unique by its curly structure. This allows to produce denser and durable material which can best serve for making felt shoes, carpets, thermal insulation panels and yurts.

Chrome-free leather

We use only chrome-free leather, which is tanned by natural means without involving any heavy metals and does not leave toxic effects on the enviroment. Unfortunately, leather is not animal free resource. Therefore, if you prefer all vegan materials, please request us via tumar@tumar.com and we will make you offer.

Natural Rubber

Natural rubber is stretchy, strong and waterproof. It is made from milky white liquid – latex which is found in certain plants. Such tree-derived rubber has minimal impact to the environment while harvesting and using the product itself. Rubber can be recycled into another product, like tyres and recycled again after the second life.

Production Process

 

We strive to minimize pollution to the environment at any stages of production. Our goal is to make natural materials accessible to more people and this is our input to maintain ecological balance, thus decrease the negative effect of industry to the environment.

Wet Felting Technology

 Sheep Shearing

Sheep shearing takes place once a year in spring. Hair shaving tool is run along a sheep’s skin without cause any pain. 

 Drying

After achieving the necessary shape, density and size, we dry them on  shoe molds.  Slippers  are then shaved on the surface to remove the loose fibers. 

 Cleaning Wool

We clean wool by removing all the dirt and raw hair. Wool fibers are then untangled, washed with hot water and dyed.

 Outsoles

After being dried, we glue and sew outsoles around the edges. Brand labels and additional bands are also sewn to the shoes at this stage. 

Wet Felting

We make felt by adding hot water and soap to the cleaned wool. By rolling felt around shoe molds we regulate the shape.

 Wastewater

The water used for the felt-making process is then cleaned with the mechanical filtering system  and provided for planting at the local farms.  

 

Sewing Technology

Preparing felt sheets

We first prepare felt sheets by wet-felting wool and regulating to achieve the necessary thickness and density.  

Cutting & Sewing

Felt sheets are then cut into shoe patterns designed for each model. The cut-outs are then sewn together on a machine.

Forming

The pre-forms are then worn on shoe molds, ironed on the outside and corrected to achieve the necessary shape.

 
 

Quality Standards

Due to the handmade production processes, some deviation from the standard parameters is inescapable. However, for each production process, quality indications are defined and checked during each stage of production. Such verification is complied with the international quality control system.

Shape

For compliance with the shape and size, each pair is measured and checked by special markings on shoe lasts.

Density

The standard is 0.27-0.28 gram / cm3. There are standardized thickness and weight measurements for each pair of felt slippers. The standard thickness for wet-felted slippers is 6.5 mm. The standard thickness for sewn slippers is 5.5 m. The soles of sewn slippers consist of two layers of felt with 4.5 mm thickness.

Color

Due to the handmade processes of production and use of heat and water, we allow 0-5%deviation from the reference color in Pantone TPX system. The quality of the applied dyes is determined by resistance to wet and dry methods of abrasion.

Gluing

The quality of gluing work (attaching a leather or rubber outsole to a slipper) is subject for external inspection and selective testing by twisting and tearing. All types of soles, except for rubber, must be stitched additionally around the perimeter of soles. The quality of glue and sole materials must be confirmed by quality certificates received by a supplier.
