Swiss Crealet offers controlled Thread Tension for Fabric Selvedges
Crealet’s long time experience in warp thread feeding for narrow and wide weaving machines and for warp knitting machines makes us your specialist in this discipline of textile manufacturing. Here are two examples in regard to selvedges: weaving brands into the selvedge and weaving of dense fabrics
Example 1: Weaving brands into the selvedge
The weaving of a brand into the selvedge serves to differentiate a product from the competitors and to underline its uniqueness. Thanks to woven-in brands customers benefit from better orientation in the market.
The inclusion of the brand into the fabric reflects a visual presence and is part of the overall corporate identity. Electronic Jacquard machines are especially suited for the inclusion of individual lettering in selvedges and in fabrics for a wide variety of applications.
Selvedge Thread Let-off CS2
In order to reach perfect quality, we recommend to deliver the selvedge threads from separate controlled bobbins.
The Key Advantages
– simple handling
– maintenance free
– independent adjustment of the selvedge threads
– reduce yarn breaks
– higher fabric quality
– for supplying fancy yarns or markers
– for all common disc coils
– Flange diam. max.: 300 mm
– Tube diam. min.: 40 mm
– Full width of bobbin max.: 210 mm
– Max. warp tension: 96 N
– Voltage supply: 24VDC
Example 2: Wavy selvedges in dense fabrics
When weaving dense fabrics, it can happen that the selvedges of the fabric are looser than the rest of the fabric. Due to the wavy fabric selvedges, such fabrics can be further processed only with difficulty, because the selvedges cannot be kept at the same tension as the rest of the fabric.
Often dense fabrics are coated in a second stage. Also during this coating wavy selvedges have a negative effect. Because of the loose selvedges a uniform coating of the fabrics is hardly possible.
These disadvantages can at least be minimized by feeding the selvedge yarn from warp bobbins to the weaving machine, which allows the yarn tension to be set accordingly.
Crealet’s selvedge let-off guarantees a constant warp tension from full to empty warp bobbin. The devices can be equipped with a tension indicator to ensure the reproducibility of the tension settings.
