    Our manu­facturing competen­cies – reliable nonwoven solutions

    We at Sandler Group are specialists in nonwoven solutions. From the selection of raw materials to the finished nonwoven: the quality of our products is our top priority. We always select the appropriate manu­facturing method to produce the best possible products. We carry out regular product controls. This includes tests by independent institutes and certi­fications. Our production technologies themselves and their further development distinguish us and our products. At Sandler, we plan and project our nonwovens lines ourselves in order to apply our technological know-how in the best possible way for the implemen­tation of the latest manu­facturing possibilities.

    Meltblown technology – nonwovens for high-per­for­mance filter media

    Meltblown technology enables the production of nonwovens with extremely small fiber diameters. The starting materials for meltblown media are granules that are first molten during the process and then spun out into the finest fibers. Thanks to these finest fibers, our melt­blown nonwovens impress with a high internal surface and are able to efficiently retain the smallest particles and dirt fragments. Optimal for use in high-performance filters.

    The thermal bonding process – nonwovens with high strength

    During the thermal bonding process, synthetic fibers are bonded by means of heat and pressure. The result is nonwovens suitable for a wide range of use(s) and particularly suitable for direct skin contact. They are therefore frequently used for processing into hygiene products, filter media or packaging materials.

      Air-through bonding – soft and voluminous nonwovens

      During the air-through bonding process, fibers with different melting points are bonded by means of hot air in a dryer. The result is soft, homogeneous nonwovens that are also extremely high-performance. Ideal for technical applications and voluminous upholstery materials.

        The Spun­lace Process – versatile nonwovens for Wipes

        In the spunlace process, nonwovens are produced by mechanical bonding. With the aid of high-pressure water jets, the individual fibers are inter­twined to form a uniform material. The finished nonwoven is used primarily in the manu­facture of wipes and other hygiene products. Excellent liquid absorption characterizes our spunlace nonwovens.

        The needle­punch pro­cess – wear-resistant nonwovens

        The individual fibers are bonded together by mechanical needle punches during the needle­punch process. In this process, the strength, density and texture of the nonwoven can be optimally controlled. This technology is used primarily in the production of nonwovens for noise and thermal insulation materials. It is also used to produce nonwovens for the home textiles sector.

          Composite materials – infinite possibilities 

          By means of ultrasonic welding, hot melt or thermal lamination, embossing or pressing, nonwovens can be bonded to nonwovens or other materials. The result: nonwovens for high-performance filters or absorbent diapers. The ability to combine different base materials creates an infinite number of nonwoven solutions for a broad range of industries.
