A point of reference in Prato’s textile industry
Founded by Ferri Ronaldo, Roccatura Lascialfari was born from a passion for textiles and the commitment of a family deeply rooted in the Prato textile district. Today, under the guidance of his son Claudio, the company continues to grow and establish itself as a pillar of the sector, thanks to expertise, innovation and dedication.


















Winding is a fundamental process for guaranteeing the quality and functionality of the yarn. This operation consists of transferring the yarn from smaller packages, such as pirns, to larger cones, ideal for subsequent processing. During this stage, an automatic knotting system is used to join the strands of yarn coming from several pirns, ensuring continuity and reducing waste.
A distinctive feature of Roccatura Lascialfari is yarn clearing, a process that makes the yarn perfect. Thanks to an advanced electronic device, any thickness imperfections are detected and removed, thus obtaining a homogeneous, high-quality material, ready to face the subsequent production stages.
The company also specialises in oiling, a crucial operation for knitting yarns. This treatment reduces the coefficient of friction, ensuring greater smoothness during processing and improving the final result of the product.
Another key service is twisting, a process that combines two or more strands of yarn, applying a rotation on their axis. This makes it possible to obtain thicker and stronger yarns, ideal for specific and customised uses.
Thanks to Claudio’s passion and continuous investment in technology and quality, Roccatura Lascialfari is today a point of reference for the Prato textile scene. The company stands out for its attention to detail and its ability to respond to customers’ needs, keeping intact the artisan tradition that has accompanied the Lascialfari family for generations.
