EFFICIENT MANUFACTURING FOR GEOTEXTILES
Geotextiles are an ever-growing market, with one prime consideration for producers - machine efficiency.
Geotextile manufacturers produce in large quantities and since the quality requirements are not so high, neither are the margins per meter. Thus, the technologies integrated in the production process make a difference in terms of profitability.
Therefore, weaving mills in this segment rely on a proven Loepfe solution from the WeftMaster series for TWO reasons.
Firstly, weaving mills achieve a high level of efficiency during the weaving process by using the WeftMaster SFB electronic weft thread brake. As the number of weft breaks can be substantially reduced, production is not interrupted - and obviously weft break repair time is also saved.

Geotextiles are used for basic functions such as filtration, drainage, separation of soil layers, reinforcement, or stabilisation in locations like road and railway embankments, earth dikes and coastal protection structures. And, of course, to aid in plant propagation by holding seeds, fertilizers and topsoil in place. In fabric production, a distinction is made between woven, non-woven and knitted geotextiles. Whereas the woven fabrics are said to have a higher resilience since woven fabrics are reinforced by thread crossing thread, which creates a strong barrier. Weaving mills are nevertheless subject to price pressure and therefore many manufacturers decide to dispense with the prewinder device. This eliminates the need for its purchase, cleaning and maintenance. While this approach contains a drawback in machine efficiency caused by different incidents, the latter can be completely overcome with the advantages WeftMaster SFB.
Secondly, weaving directly from the bobbin creates yarn tension differences due to the diameter differences of a full bobbin and an almost empty bobbin. This leads to weft breaks, loose weft, weft burst and lost weft. The WeftMaster SFB compensates for the tension differences perfectly and prevents all of these issues and weaving directly from the bobbin goes effortlessly.
