Twisted chain warp yarns offer considerable savings over cotton spun yarns because of the increased length of yarn per kilo which results in fewer beam changes and better production efficiency. Polypropylene chain warp yarns are more stable, have less elongation and reduce creep more than polyester blend yarns. This gives a better interlock within the carpet construction.

Bonaclave

Bonar's autoclave yarns are steam treated at a temperature of 150°C. The principal benefits are near zero shrinkage on every metre of yarn, twist retention and general stabilisation of yarn configuration, especially for an open weave carpet construction.

Bonastuffer

Bonar's polypropylene stuffer warp yarns are specifically made with minimum extension and minimum shrinkage to provide a stable back for all woven carpets. High twist levels ensure better weavability.

All Bonar's stuffer warp yarns can be made twist-set for higher beaming efficiency. This extra treatment to the yarn eliminates the natural twist liveliness of polypropylene fibrillated yarn.

Bonaweft

Bonar's polypropylene weft yarns, twisted or untwisted, are made to very tightly controlled shrinkage specifications enabling the carpet to be processed through the latex finishing operation without fear of shrinkage. The uniformity of the yarn ensures smooth running and reduces stoppages caused by yarn breaks.

Additionally, Bonar has developed 89 Tex and 105 Tex yarns to satisfy the demands of clients requiring in excess of 1.5 million knots per square metre. All Bonar weft yarns are available either lubricated or unlubricated.

Bonaflame

Bonar's flame retardant yarns meet stringent health and safety requirements and are manufactured under our ISO 9001:2000 Quality Control System. Bonaflame yarns help the finished carpet system meet international FR standards. They are particularly well suited for specialist areas including aircraft and shipping line carpeting.

Bonaeco

Bonar Yarns has developed a recycling program which could have a dramatic impact on the way in which polypropylene carpet backing yarns are produced in the future. Using a dynamic process, Bonar are developing PP warp and weft yarns made from 100% recycled material that technically meet all tex and shrinkage requirements consistently, so that the quality of the end product is in no way compromised.

In addition to BonaEco, Bonar’s regular range of fibrillated polypropylene yarns are recyclable. In conjunction with polypropylene pile yarn, these carpets can be reprocessed more easily than those with mixed fibre yarns.
