Investigación, desarrollo, innovación y tecnología

At Sati Envirotech company, the ideas do not come due to the short moments of inspiration! The ideas are studied , analysed, discussed, improved and, finally, developped only if they are good ones. This way of work is based on research and development of technical fabrics.

Production - SATI Envirotech Technology

Since 2015 the new workshop has been located in Caldes de Montbui.

With the surface over 6,000m2, it contains the whole production process : warping, weaving, treatment and quality control.

This complete production process allows us to control and secure  every step of manufacturing till the product delivery  to our clients.



A production facility comprising numerous high accuracy electronic weaving looms  Sulzer and  Dornier  which allow manufcaturing of fabrics with width over 300cm.
We are actually capable of producing more than  1,5 million linear meters of fabrics per year with over 30 weaving looms.
Due to our experience of more than 50 years in fabrics manufacturing for industrial filtration, we can offer the wide range of technical fabrics.
We have developed over 500 various fabrics and we still continue our research and development of new materials in accordance with  our clients' requirements.
Our fabrics are used in a big variety of industrial sectors.


SATI Envirotech also has all the necessary materials for fabrics treatment according to the clients' needs, the sector of activity and application.

  • Heat setting
    This thermal process allows fabrics dimensional stability in order to  avoid its possible shrinkage later. SATI carries out this type of treatment with all their fabrics to assure the initial quality of the product.
  • Calendering
    The calendering process is  to adjust the air permeability of the fabrics, that allows to vary their physical properties. This process can stabIlize, polish and smooth fabrics surface.
  • Singeing
    Due to the singeing process, the loose fibres on the fabrics surface are removed which improves the cake release from the fabrics or  felt surface.

Quality control

During the whole production cycle we carry out various tests, laboratory trials, measurements,.. as well as thorough and strict quality control; this allows us to guarantee the high quality of  SATI Envirotech products.
