Bico BCF Yarn Approval from Barmag and Object Carpet

Collaboration Between Barmag and Object Carpet in Carpet Yarn Production

German carpet tile manufacturer Object Carpet, operating in the commercial and residential floor coverings sector, has collaborated with textile machinery manufacturer Barmag on Bico BCF carpet yarn production [1], [3].
Barmag, specialized in textile machinery manufacturing, is part of the Swiss-based global industrial group Rieter, and the company is headquartered in Remscheid, Germany [1], [2].
The company's BCF carpet yarn technologies, polymer extrusion and filament processing systems are developed at the Neumag business unit located in Neumünster, Germany [1], [2].
This joint industrial project is based on the principle of simultaneously bringing together two different polymer components within a single filament cross-section [1].
The objective of this structure is to impart bulk to the yarn [1].

Bico BCF Yarn Structure and Bulking Mechanism

The fundamental engineering principle of Bico BCF technology relies on utilizing the differing physical and thermal shrinkage characteristics of polymer components within the filament cross-section [1].
On the spinning line and during subsequent fixing and heat-treatment stages, two separate polymers within the same filament exhibit differential shrinkage behavior [1].
When one surface of the filament shrinks more than the other surface, the resulting internal stresses cause the yarn to curl spirally on its own without requiring an external mechanical texturing process [1].
Thanks to this differential shrinkage mechanism, a three-dimensional wave and natural bulkiness occur along the filament [1].

Safety Norms and International Quality Standards

Fire performance and environmental standards of carpet yarns are evaluated under international norms [6], [7].
The EN 13501-1 standard determines reaction-to-fire classification for floor coverings and carpets [6].
ISO 14001 is a certifiable environmental management system standard [7]; color fastness is evaluated using AATCC methods [8].
