The weaving mill was established in 1977 and is today run by Frank Hansen who is third generation of a family of weavers. KE Fibertec weaving mill exclusively manufactures fabrics for textile duct ventilation which is a unique situation on the global market, and which gives us a valuable know-how on the woven materials to the benefit of our customers.
To have our own state of the art weaving mill just across the parking lot gives KE Fibertec a very flexible supply chain, that can meet our demands and requests on especially quality control and supply security.
KE Fibertec weaving mill has very strict demands on suppliers of yarn, and all raw materials are subject to extensive input control to ensure that the permeability is unchanged even after many washes. All permeable KE GreenDuct materials are produced with materials from the KE Fibertec Weaving Mill.
Entry Control (Raw Materials)
In the entry control phase our yarn's colour, shrinkage, and oil content is carefully checked. Our weaving mill won’t allow a colour difference of any more than 1 ΔE. The normal shrinkage rate of standard polyester or TCS is from 8-12 %, but we won’t accept any yarn with a shrinkage rate of more than 5 %. This is to ensure that the permeability of our textiles remains static and standardized throughout the production process, from the weaving loom all the way to the finished product and beyond. That means you’ll never have to worry about shrinkage from washing cycle to washing cycle.
The normal amount of spinning oil is between 3.5-7% added in the spinning process. But once again we impose a far stricter oil content limit of just 1%. This ensures that any remaining oil will be evaporated off in the heat setting of the finished product without altering our textile’s permeability.
After heat setting, our textiles are sent off for inspection, where a set of human eyes susses out any defects or irregularities. The product’s permeability is given one last check and, if everything looks good, is finally approved. We measure the textile’s permeability with a portable handheld testing device, which provides precise measurements from the entire width of the textile (between 50-70 measure points all across the width). Whenever a textile’s permeability falls beyond our approved range, the entire roll is destroyed and begun anew.
Each roll contains a barcode with 11 identifying marks.
These specify the textile’s:
- Air permeability
- Length in metres and m²
- Loom number
- Lot number of yarn
- Date of production
This gives us full traceability on every roll we produce - from cradle to grave.
Entry control (Duct Production)
Before forming the textile roll into the final duct we once again check that its permeability, colour and strength are up to par.
