Mussock Saffron Cotton Yarn

The only NZ importer of Saffron Cotton Yarn — the industry standard for commercial mussel socking.

Ritex International is the exclusive New Zealand importer of Saffron Cotton Yarn — the industry's most trusted yarn for mussel socking applications.

Designed specifically for use on Mussock machines originally developed by Andy Joines, Saffron yarn delivers consistent strength, uniform twist, and dependable performance across both Mussock and continuous-rope cultivation systems. Produced to tight tolerances, it minimises tearing, slippage, and breakage during continuous operation.

The yarn holds its integrity through crop establishment, then breaks down naturally in the marine environment once mussels are securely attached. That balance between strength and degradability sets it apart from general-purpose cotton yarns.

Stock is held locally in Nelson for fast nationwide dispatch — giving growers reliable access without depending on offshore lead times. Standard stocked lines include 12/1 and 16/1 cotton and 20/1 poly-cotton for knitting. Additional counts can be sourced on request.

For New Zealand producers, the ability to source this yarn locally through Ritex — without relying on long offshore lead times — supports planning, continuity, and efficient in-season operations.

Why choose Saffron Mussock Yarn?

Saffron yarn is produced in the most widely used counts for NZ mussel farming, with 12/1 and 16/1 held in stock and additional specifications available on request. Each batch is manufactured to stable twist and low variation, ensuring predictable performance on commercial Mussock machines.
Developed specifically for Mussock systems, this yarn feeds smoothly through continuous runs. The uniform construction reduces breakage, improves machine efficiency, and supports reliable socking across small-scale and high-volume operations alike.
Every line is manufactured under tight quality controls, providing reliable tensile strength and uniform twist during crop establishment. The degradation profile is designed to hold as long as needed — then break down naturally in the marine environment once mussels are fully set.
Ritex carries stock locally in Nelson for fast nationwide dispatch, providing flexibility for farms of all sizes. Larger volumes can be imported on scheduled shipments, giving growers consistent access to the quantities required throughout the season.
