Company anniversary - 30 years of textile production in Germany

16 December 2020

The knitting factory Helmut Peterseim in Mühlhausen turned 30 on December 14th. We warmly congratulate on the company anniversary! Industrial production of textiles and clothing is still an exception in Germany today. And the knitting factory in Thuringia is such an exception. Shortly after the fall of the Berlin Wall in 1990, Helmut Peterseim founded Peterseim Strickwaren GmbH. It was time to take advantage of new opportunities and turn a vision into a company. Over the years, the knitting manufacturer had to adapt its structures and products, be open to new possibilities, demonstrate a willingness to innovation and show readiness for change. With this, Helmut Peterseim managed to defy all adversities in the textile sector. Before he retired, in 2017 he handed the company over to a group of shareholders who also represent his views of tradition, value and innovation. High-quality production of knitwear in Germany as sustainable action in the time of the new economy. Together with their loyal employees, they pursue their motivation "presence consists in niches and intrinsic value" and this motivation is what makes the company so successful.

30 years of knitting from Germany - that deserves a big applause. Congratulations!

Here you can read how the company Peterseim Strickwaren GmbH looks back on a successful existence with a lot of creativity and perseverance and what drives it further on.

Together through the corona pandemic

9 December 2020

Shortly after the new year 2020 started, the virus pandemic Covid-19 spread across the world. The pandemic has a huge impact on all areas of our lives. The fashion industry in particular had to react quickly in order to hold the existing supply chain framework together. We are now in the last month of 2020. The corona pandemic still has the world under control, but we are slowly learning to deal with it, to continue to operate creatively and to defy the situation through value in material and quality in production.

We asked our two business partners, the Peterseim knitting mill in Mühlhausen and the Woolyarns spinning mill in New Zealand, about their summary of the effects of the corona pandemic. Despite all the difficulties, we stick together and look forward to the new year 2021! is forward to the Swedish fashion market

Hall B2 / 02G does the pilling test

22 February 2019

What is pilling? We speak of pilling when small fibers loosen from the wool due to friction while wearing an item of clothing and form pebbles. What about pilling with our products? We wanted to know and sent knitting samples to a laboratory. With the Martindale method, our two yarn blends were tested according to the pilling behavior DIN EN ISO 12945-2. The knitting samples were subjected to a mechanical friction of 1000 turns against each other. Our yarn mix of merino, possum fibre and silk achieved only a slight and isolated pod formation on the wool material with this high number of tours. The cashmere-possum fibre-silk mixture showed no change with the same number of tours. The very positive result is due to the possum fibre. This component in our mixture ensures that the nodule formation remains in the range of the natural low-pilling effect. This means that our knitwear will retain its place in the wardrobe of every wool lover for a long time.

Think spring, wear Summit by

29 March 2018

Spring is in the starting blocks. The icy temperatures are over, the snow begins to melt and lures the first buds on the branches. With the warm rays of the sun, the flowers show their delicate colors and leave behind the monochrome winter landscape. For our new fashion label Summit by, we were inspired by the delicate colors of spring. In the cool silver color and the pastel bloom we are starting the spring with a new yarn mix. The fine cashmere-possum-silk mix makes the knit even softer and light as a feather. What is so special about this spring companion? Find it out in the current magazine of natural nature.
