technical needle felt

for quality products and special applications

Our innovative technical textiles are the first-choice material in many quality products and special applications. Nonwovens from Lydall Gutsche are ideally suited for the combination with other fabrics. This makes them the basis of individual composite fabrics which serve as carrier material, filter medium or insulation material.

We fulfil complex requirements: In close cooperation with our customers, we look for suitable composite materials, such as foil, fabric and equipment, and take care of the perfect lamination, manufacture and wrapping. This ensures that our customers receive customised solutions, perfectly tailored to the individual operation requirements.

We process all common fibres in our highly-functional needle felts - pure fibres, homogeneous mixtures or layered structures

Fibre properties at a glance:

mechanically high-strength (e.g. aramid fibres)

chemically stable (e.g. PTFE, polyimide)

flame-retardant and non-combustible (e.g. polyester flame retardant)

standard polymers (e.g. polyester, polypropylene)

compliant to EU and FDA regulations

Filter mediA

our gutsche porotex^® product programme

Dust and flue gases which are harmful to our environment are the by-product of many incineration and production processes. Thanks to our innovative filtration media, particles can be filtered out highly efficiently, ensuring for example optimal flue gas cleaning. We stand for perfectly customised solutions and excellent service on-site around the clock. As reliable partners, we support our customers from the first product idea to the supervision of the final filter solution in daily operation.

Our high-performance filter media can be ordered as rolled material, and as manufactured filter bags. Our valued customers can benefit from our many years of experience in numerous, demanding sectors.

Every single brand of the GUTSCHE porotex^® filter media programme stands for an innovative, tried and tested solution for the future. Insiders associate highest quality and efficiency with our products.

advantex^® combines the economical features of a mineral scrim, with the positive characteristics of a needlefelt. This results in a high temperature filter medium, which is not only low in cost, but provides the flexibility and efficiency to ensure lifetimes and outlet emissions, which are comparable to many conventional high temperature needlefelts.

condutex^® is our product range for customized conductive filter media. This media is tested to DIN 54345 part 1 and 5 by accredited institutes and is also tested during production.

With microvel^® the direction is now heading towards zero outlet emissions. By using the micro-batt technology, which results in a significantly higher filtration surface and -efficiency, we are leading the way with a new generation of micro-webbed needlefelts

antafin^® a highly effective, anti-adhesive treatment for greasy and oily dusts. Resistance to acids, hydrolysis and other chemicals is increased and at the same time the cleaning performance is improved.

With membratex^® the surface now offers a “cake grab” feature which encourages the build up of an homogeneous filter dust cake. This filter cake is essential for the reaction of additives with most harmful flue gas components.

With optivel^® we use the positive features of different fibres has enabled us to manufacture blended needlefelts for a wide range of applications The blend of PPS and PI in filters on coal fired boilers and the blend of PAN and PES in cement or metallurgical applications, has helped to achieve far better results than either 100 % polyester or polyacrylic felts.

createx^® involves the combination of an optimised needlefelt with a PTFE membrane. This development has made it possible to add to the existing characteristics and advantages of a modern needle felt, combined with those of a PTFE membrane, resulting in the lowest possible dust emissions and the highest filtration efficiency.

mpt is a microporous coating based on polyurethane for GUTSCHE filter media. The product has been used successfully in technically demanding applications, with difficult to handle dusts, materials and gases, especially where an extremely low emission rate has to be achieved.

sparktex^® is a heat protective barrier that prevents damage to the needlefelt substrate. It effectively protects against sparks, smoldering, glowing and burning particles and provides a high separation efficiency.
