From Detection to Trust: Quality at Hilandería Lurín

Hilandería Lurín in Peru, part of the Idetex Group, is one of South America’s most modern cotton spinning mills and a leading producer of premium yarns for demanding international markets.

Mr. Manuel Tenorio, Plant Manager at Hilandería Lurín, explains the reasons behind the mill’s recent investment in advanced contamination control. To further strengthen its quality assurance strategy, Hilandería Lurín selected Loepfe’s YarnMaster® PRISMA DMFP as the final quality control solution in winding, complemented by a Loptex EXA in pre spinning — a combination that ensures comprehensive contamination control across the entire production process.

Overcoming the limits of conventional detection

Before upgrading, Hilandería Lurín faced challenges typical for mills serving high-end customers:

• Rising demand for contamination free yarns
• Limited detection of certain colored foreign fibers
• Risk of costly claims due to undetected contamination
• Pressure to improve quality without sacrificing efficiency

As global quality standards tightened, it became clear that conventional yarn clearers were no longer sufficient to meet premium export requirements.

Additionally, installing a Loptex EXA contamination sorter in the pre spinning process has further strengthened results across the entire production line.

Would you recommend PRISMA to other spinners and why?

• Absolutely. Any spinner targeting premium yarn quality and high production efficiency will benefit from PRISMA. It combines exceptional detection precision, reliable yarn clearing performance, and strong local support, a combination that is critical for consistent results in demanding markets.
