Nonwoven - Measuring systems and process control for non woven fabric

Solutions for the production, processing and finishing of non woven material

Due to its versatile properties, nonwoven is used today in countless industries for numerous purposes. The production of non woven fabric is a complex and costly process in which quality control plays a special role. Depending on the requirements, staple fibre nonwoven, meltblown nonwoven, spunbonded nonwoven or wetlaid nonwoven is used for web formation. After web formation, the non woven web is bonded by thermal, chemical or mechanical processes. Mechanical web bonding produces, for example, needlepunched nonwoven and hydroentangled nonwovens. A final process step is nonwoven finishing, in which the non woven material is given special properties such as flame retardant, hydrophilic or oil repellent.

Non woven web is used for a wide variety of applications. A large field of application is hygiene and cleaning products. These include diapers, interlinings, wet wipes, microfibre cloths or vacuum cleaner bags made out of non woven web. Medical products such as surgical drapes and gowns, mouth-nose protection masks, dressings or plasters are also made of nonwoven. Non woven materials also are often found in technical applications such as geotextiles for drainage layers or erosion protection. Nonwoven filters, insulations and decorative components in the automotive sector, prepregs for transformers or battery separators are also included. This list for non woven applications could be continued endlessly.

For the entire nonwoven sector - whether wet wipes, diaper components, non woven geotextiles or medical nonwoven - Mahlo supplies a quality control system that is tailored to the specific application and your individual measurement and control requirements. 
Systems ranging from fixed measuring points to traversing measuring systems for single and double-sided measurement with several synchronized scanners are available.
We use different methods such as beta radiation, X-rays, near infrared or white light interference for quality measurement. Decisive parameters such as thickness, moisture, basis weight or layer thickness can be determined. We also have the possibility to control fabric width, air permeability and static charge.
Many of the renowned manufacturers of non woven fabric trust Mahlo’s longstanding experience in on-line process monitoring and control technologies. Our expertise reaches back several decades, and we strive to improve ourselves every day, to optimise efficiency and quality of your production process. 
 

Our experience in the nonwoven sector and corresponding understanding of process control enables Mahlo to tailor systems especially for the following processes
  • Airlaid / Dry Laid
  • Carded
  • Hydroentangled
  • Melt Blown
  • Needlepunched
  • Spunbond / SMS
  • Spunlaced
  • Wetlaid
  • etc.
