Group Business Overview

Continuing our tradition of innovation, today we have a full line of fabrics that are used in the most demanding applications such as seawater desalination, food and dairy, pharmaceuticals and others. Our permeate carrier fabrics are preferred by the world’s leading filtration companies due to our capability to produce extremely thin fabrics with industry-leading consistency. This allows the filter to be more energy-efficient and improve output.

Welknit has a full line of epoxy coated and BPA-free bi-component fabrics for any application. We have options for ultra-high or low pressures, high pH or low pH feed solutions and our fabrics are optimized to ensure maximum performance.

Because our fabric is the last thing that the permeate touches before leaving the filter, our products and manufacturing plants are Food and Drug Administration (FDA) compliant and National Science Foundation (NSF) certified.


The technical production processes at Welknit include the most advanced techniques, including carbon fiber knitting and finishing machines, and we are continually researching new material and machinery to create innovative design effects and performance properties.

We believe that Manufacturing Excellence is delivered through:

  • Philosophy of Lean Enterprise
  • Real-time data
  • Focus on process efficiencies through Six Sigma techniques
  • Unique machinery modifications
  • Investment in high speed and high capacity machinery
  • Cost down and cost out culture throughout the organization
