Fibrillated fibres - Pulp
Fibrillated fibres have the same characteristics as fibre fillers and short chopped fibres of the same base material e.g. the required chemical resistance and mechanical strength. The main difference between fibrillated fibres and chopped or ground fibres is their fibrillated structure (fibrils) and their exceptionally large fibre surface. These properties create effects which cannot be achieved with unfibrillated fibres.
For many years STW has sold fibrillated polyethylene and propylene "pulp" under the trade name SWP. Recently we have commenced production of fibrillated fibres made from polyacrylonitrile, aramid and Lyocell. These successfully complement our range of products.
P PAC - Polyacrylonitrile pulp
We designed a process specifically aimed at producing polyacrylonitrile pulp. This was developed to maximise pulp fibrillation. Now, with the help of this technology, we are fibrillating a diverse range of raw materials. The most outstanding characteristic of these pulps is the exceptionally large surface area of up to 35 m2 /g fibre, depending on the type. The vast surface area of these pulps is key to their application. There is no production limitation on the quantities of pulp we can produce.  |

Approximate length and surface area:
P PAC 841 3,5 mm > 35 m2 /g
P PAC 843 2,5 mm > 35 m2 /g
P PAC 845 1,5 mm > 35 m2 /g
P PAC 851 3,0 mm > 15 m2 /g
P AR - Aramid pulp
The above technology also enables the production of aramid pulp which is a recycled product, and therefore only available in limited quantities. There are distinct applications which require of this pulp.
Approximate length and surface area
P PAR 2,5 mm ~ 8,5 m2 /g
PLY - Lyocell pulp
Lyocell is a chemical fibre based upon cellulose, produced in a special ecologically friendly spinning process. In comparison with viscose fibres, Lyocell fibres have significant advantages regarding dry and wet strength.
Approximate length and surface area
PLY 861 ~ 3,5 mm > 2 m2 /g
PLY 863 ~ 2,5 mm > 2 m2 /g
PLY 865 ~ 1,5 mm > 2 m2 /g
More Informationen STW produces fibrillated fibres from polyethylene and polypropylene under the name SWP. The main difference between these fibrillated fibres and cutted or grounded fibres are the fibrils which means the structure is more branched and the surface much bigger.
With the fibrillated fibres from polyacrylonitrile, aramid and Lyocell which are obtainable under P PAC Polyacrylonitrile pulp, PAR Aramid pulp and PLY Lyocell pulp, the Schwarwälder Textil Werke Heinrich Kautzmann GmbH increased its range of products.
Products of our range are fibres made from fibrillated fibres, polyethylene, polypropylene, SWP Polyacrylonitrile, aramid fibres, Lyocell, P PAC Polyacrylonitrile pulp, PAR Aramid pulp, PLY Lyocell pulp, fibre fillers, short cut fibres, pulp from aramid, fibrids, pulp from Lyocell, pulp from polyacrylonitrile, cellulose, cotton fibres, jute fibres, viscose fibres, hemp fibres, sisal fibres, polyacrylonitrile fibres, polyamide fibres, polyester fibres, polypropylene fibres,
polyvinyl alcohol fibres, peroxidised PAN fibres, carbon fibres, mineral fibres like mineral wool fibres, glass fibres, synthesis pulp, polyester cord fibres coated with latex, cord threads, thixotropy fibres, light-weight silica fillers, pieces from cotton fabrics, cellulose fibres and rayon.
A special process especially developed for the production of P PAC – Polyacrylonitrile pulp serves the purpose to produce highly fibrillated fibres. This process enables us to produce fibrids from the different kinds of raw material.
The outstanding properties are the big surface of the fibre which is again a criterion for the prevailing application of the pulp. On principal, pulp is available in unlimited quantities.
It is also possible to produce PAR Aramid pulp with the same technology. This Aramid pulp is exclusively produced on the basis of recycling. However, there are applications where this pulp finds its employment beside the fibre fillers like cotton fibres, viscose fibres, hemp fibres, flax fibres, jute fibres, sisal fibres, as well as polyamide fibres, polyester fibres, polyacrylonitrile fibres, polypropylene fibres, polyvinyl alcohol, aramid fibres, carbon fibres, glass fibres, mineral wool fibres which we have been producing since years.
Lyocell is a chemical fibre which is produced in a special environmentally friendly procedure of spinning on the basis of cellulose. In comparison to a viscose fibre the Lyocell fibre is has considerable advantages due to higher dry- and wet strengths.
This fibre available under the name PLY – Lyocell pulp, is used amongst Polyolefin fibres, cotton fibres, cellulose fibres, polyacrylonitrile fibres, rayon, fibrids, polyethylene and polypropylene as well as short cut fibres produced from polyacrylonitrile fibres, polyamide fibres, polyester fibres, polypropylene fibres and rayon for several applications.
Our fibres from cotton, cellulose, polyacrylonitrile, rayon, polyethylene, polyamide, polyester and polypropylene can be used amongst other applications for safety papers, malleable papers, cement slaps, isolations for catalytic converters, friction linings, filter papers for the car industry, the building industry and also for the food industry.
