SINTEF test Lanullva - Tested under extreme conditions

Lanullva SINTEF test Lanullva - Testet under ekstreme betingelser

The wool underwear that came out best - Thanks to a completely unique knitting method

From a dilapidated old prayer house in the village of Lyngstad, Brit sat and knitted the wool sweater that would eventually turn out to win awards and come out best in Sintef reports.

The year is 1995.

Brit is called by Arvid Påsche who has heard about a revolutionary wool sweater that kept someone warm, in extreme cold down to -40 on Svalbard. He wants to come on a company visit.

Modestly, Brit replies that she knits her woolen products in a basement of an old prayer house.

Arvid takes the trip anyway, because this knitting technique was something he had to look into more closely.

Field testing of Lanullva Underwear

The test took place in Svalbard, where the woolen underwear was used as the only undergarment under a padded snowmobile suit in -23 degrees and at a speed of 60km/h.

For temperature monitoring, sensors were attached to the calf, thigh, stomach, chest, shoulder and upper back area.

Evaluation of Lanullva wool underwear

Extreme working environment July 1997

The underwear has been tested by SINTEF and its own extensive customer group who have used the products under various climatic conditions, and have demonstrated very good thermal properties, and with a small degree of sweat accumulation in the clothing during physical activity.


It has been established that wool underwear with a loose structure does not develop/accumulate sweat odor as quickly as a lot of synthetic fiber underwear.

The thermal properties of underwear are directly related to the air content of the garments. Rather, the knitting method. The greater the air content in the garment, the greater the garment's insulating properties.

Evaluation of Lanullva wool underwear

The products tested were Lanullva and 2 other wool manufacturers in addition to standard cotton underwear.

Execution

The test was carried out at SINTEF Unimed's climate laboratory during the summer and autumn of 1999.

6 people – 1 woman and 5 men – took part in the testing.

The total exposure time was 2 hours in -6 degrees.

They alternated between physical activity for 40 minutes, rest for 20 minutes, before another period of activity and rest.

Thermally assessed, Lanullva scored the highest and throughout the trial period was considered to be the warmest. Also kept the people warm during rest periods. The cotton underwear is rated as the coldest

Of the 4 types of wool underwear, the Lanullva products have the best thermal properties, and appear as a product for extreme conditions. The thermal properties of underwear are directly related to the air content of the garments.

The greater the air content in the garment, the greater the garment's insulating properties." -Head of Research, Arvid Påsche.

Britain won The Reodor felgen prize in 1995 for his innovative thinking.

A revolutionary knitting method that keeps you dry and warm, even in extreme weather conditions and high activity.

That is why we always talk about air having to enter the garment for maximum insulation and ventilation. This knitting method, which captures the air in each small stitch, is what makes our wool even better.
