The Natural Laboratory
Taiwan organic cotton fabric mill, HerMin's project studies the science of bionics in order to transfer natural features and phenomena to textile surfaces with a focus on renewable raw materials such as cotton, wool, and linen as well as cellulose and palm fibers. The goal is to highlight the natural characteristics of these materials and to combine them with the newest weaving, yarn, and equipment technologies. The resulting fabrics are a natural alternative to modern synthetic materials and are manufactured in harmony with the environment.

Waterproof Cotton Fabric
Taiwan organic cotton fabric manufacturers, HerMin's waterproof cotton fabric is made from extra thin and long-staple cotton fibers using a very tight and traditional weaving technique. When dry, the fabric opens up its pores to breathe. When wet, the overtightened cotton fibers swell, thereby sealing the weave and making it waterproof.
Depending on its intended application, the material is available from 200 to 286g/sm and presents a true alternative to hardshell synthetic fabrics. GOTS certified organic cotton fabric options are available.

Downproof Cotton Fabric
HerMin organic cotton mill's wind and down proof fabric is manufactured from thousands of thin cotton fibers with special weaving techniques. Based on the principles of geological compaction, the weave is durably compacted using pressure and temperature, thereby giving the material its characteristic glossy appearance. No coating of any sort is applied.
The material is available in cotton and Tencel in a ripstop weave, between 90 to 100gsm. It is a natural alternative to lightweight synthetic cotton. GOTS certified organic cotton fabric options are available.

BioShell
Our fluffy cozy fabric is manufactured using 100% natural fiber. Unlike traditional fleece, through the finishing process, we do not create any microplastic and are completely biodegradable. The extra refined brush effect provides natural warmth and insulation, while the piles are kept sturdy. This creation is currently the most natural alternative to synthetic softshell products. GOTS certified organic cotton fabric and Tencel options are available.
