Jet strips are used in a number of product applications: from producing synthetic leather substrate, to filters or automobile equipment in the technical sector, all the way to medical and hygiene products.

According to a recent study, the wipes market is estimated to be 14.8 billion USD. Almost 1.1 million tons of sanitary wipes were consumed in 2016, and this will increase annually by 6.1% to 1.4 million tons by 2021; a market that is valued at 19.6 billion USD.

Micrometer precision – precision tools from Groz-Beckert

Hydroentanglement makes up the greatest share of production processes producing wipes today.

The key tool in any hydroentanglement system is the jet strip. At Groz-Beckert, these tools are included within the Subdivision Felting under the name HyTec®. The product range includes jet strips at a total length of 80 mm to 6,200 mm and 40 to 20,000 nozzles in one, two, three, or four rows. The nozzle diameters range from 0.08 mm to 0.22 mm. The Groz-Beckert production process absolutely guarantees sharp-edged, homogenous nozzle edges and geometries.

High lifetime, absolutely homogenous jet creation with large impelling force and excellent entanglement ensure the very best productivity, quality, and efficiency. This means that you, the customer, will always have the best possible product to reach your individual goals.

Under high pressure – bonding of nonwovens via jet strips

During the process of bonding nonwoven fabrics, water is fed at high pressure (between 30 and 420 bar) uniformly through the working width of the nozzle bar or injector, and then through the nozzle openings of the jet strip located in the injector. Water jets created in this way strike the fibrous web at a speed of up to 280 m/s, which is faster than the standard traveling speed of a passenger jet.
