Polyester, Viscose & Nylon: The Three MMF Families

Imagine three fabrics that all get lumped together under the single label 'man-made fibre', yet start from three genuinely different raw materials and manufacturing chemistries, one built from petroleum, one built from wood pulp, and one built from a different petrochemical process entirely. Polyester, viscose and nylon are exactly this trio, and understanding which is which matters because their entire supply chains, cost structures and environmental footprints differ considerably.

Polyester, by far the dominant MMF globally and in India, is a fully synthetic fibre derived from petrochemicals, connecting it directly to the same naphtha-cracker value chain covered under Fertilisers & Chemicals elsewhere on this site, meaning polyester prices and availability track oil and petrochemical markets rather than agricultural or forestry cycles.

Viscose, sometimes called rayon, works completely differently, it's a regenerated cellulose fibre made by chemically processing wood pulp into a fibre that behaves similarly to cotton, softer and more breathable than polyester, connecting viscose production to forestry and pulp supply chains rather than petrochemicals, a genuinely different raw material dependency from its synthetic MMF cousins.

Nylon, the third major MMF family, is also fully synthetic like polyester but chemically distinct, prized specifically for strength and elasticity, widely used in hosiery, sportswear and industrial applications like ropes and nets, and its raw material chain again ties back to petrochemical feedstocks, meaning two of these three fibres, polyester and nylon, ultimately share the same upstream vulnerability to petrochemical price swings that the broader MMF push covered elsewhere on this site is trying to scale up despite that dependency.
