Crude correction widens polyester edge, Indian spinners shift to blends

...

A sustained correction in global crude oil prices is beginning to alter the economics of India’s yarn and fabric industry, with cheaper petrochemical feedstocks widening the cost advantage of polyester over cotton. The decline in crude benchmarks has filtered through purified terephthalic acid (PTA) and monoethylene glycol (MEG), the principal inputs for polyester production. Domestic chemical producers have adjusted pricing in line with softer Asian import parity, bringing virgin 1.4-denier polyester staple fibre (PSF) prices down to Rs 98-103 per kg.

The impact has moved beyond staple fibre. Drawn textured yarn (DTY) and partially oriented yarn (POY) prices have also reduced, giving relief to spinning mills, powerloom operators and downstream manufacturers in Gujarat, Maharashtra and Tamil Nadu. For mills, the timing is significant. Export demand remains uneven, while Indian suppliers face aggressive pricing from competing manufacturing hubs such as Vietnam and Bangladesh. Synthetic raw-material procurement costs have reportedly declined 5-8 per cent over the past two quarters, creating an opportunity to defend conversion margins.

But falling prices have also exposed another vulnerability: inventory. Mills that purchased polyester fibre during earlier feedstock rallies are facing valuation pressure as replacement costs fall. This is encouraging a move towards shorter inventory cycles and procurement formulas linked more closely to weekly petrochemical benchmarks.

The fibre gap

The fundamental change lies in the widening gap between cotton and polyester economics.

The raw-material comparison becomes even more significant after processing losses. Shankar-6 cotton at Rs 161-167 per kg can effectively approach Rs 185 per kg once cleaning and spinning losses are considered. Polyester, by contrast, remains near Rs 101 per kg on an effective mill-input basis. That shows a cost gap of close to 45 per cent, giving spinners a strong incentive to increase the synthetic component of blended yarns.

Blending becomes the hedge

The result is a shift from fibre substitution as a tactical decision to blending as a margin-management strategy. Instead of relying on conventional 50/50 polyester-cotton ratios, mills can increase polyester content to 65  per cent in applications where price, durability and performance are more important than a pure-cotton proposition. Such changes allow manufacturers to reduce exposure to cotton volatility without abandoning cotton altogether.

The economics also place a ceiling on how aggressively cotton prices can rise. If cotton becomes sufficiently expensive, downstream buyers have an increasingly viable alternative in poly-cotton yarns and fabrics. This dynamic is particularly relevant for mass-market apparel, uniforms, casualwear and institutional clothing, where the material specification is often more flexible than in premium or sustainability-led categories.

Surat has the advantage

The shift is already visible in India’s synthetic textile clusters. Surat’s weaving industry has benefited from lower PSF costs by expanding poly-cotton and poly-viscose production. Micro-denier fabric manufacturers and water-jet weaving units are using synthetic-rich yarns to compete against cotton-dominant manufacturing centres.

The cluster’s ability to engineer lighter blended fabrics with cotton-like drape and breathability is also expanding its addressable market. Suppliers can serve garment manufacturers in Noida and Bengaluru while retaining a cost advantage over comparable all-cotton fabrics.

Bhilwara is following a similar path. Suiting and spinning companies are adjusting seasonal product mixes towards synthetic-rich blends, particularly for formalwear, uniforms and institutional orders. Blended fabrics priced 20-25 per cent below comparable cotton alternatives provide a useful buffer against weaker demand and higher operating costs.

Exporters face a tougher choice

For garment exporters, the fibre spread is becoming an important sourcing variable. Tiruppur and NCR manufacturers are under pressure from international buyers seeking lower landed prices while simultaneously shortening working-capital cycles.

Poly-cotton knits and synthetic performance fabrics allow exporters to manage those pressures in products such as casual tops, athletic shorts and loungewear. The immediate benefit is straightforward: lower material costs can help exporters defend prices without entirely sacrificing factory margins.

However, the strategy creates a sustainability dilemma. Virgin polyester remains significantly cheaper than recycled polyester. Domestic rPET is estimated to command a Rs 15-20 per kg premium over virgin fibre because collection, sorting and recycling capacity remain constrained. Consequently, exporters face a trade-off between short-term cost competitiveness and the growing demand from international brands for recycled and traceable materials. European circularity regulations and Digital Product Passport requirements are likely to make this trade-off more consequential. The cheapest fibre today may not necessarily represent the lowest compliance-adjusted sourcing cost tomorrow.

Integrated players gain resilience

The changing economics also favour integrated producers. Reliance Industries, with operations spanning PTA, MEG, polyester staple fibre and filament yarns, is positioned across multiple stages of the synthetic value chain. Its expansion in specialty fibres and recycled polyester gives it additional exposure to both conventional cost-driven demand and the emerging circular-material market.

For independent spinners, the challenge is different. Lower polyester prices improve current margins but increase the risks associated with inventory accumulation and commodity volatility. India’s textile industry is therefore entering a phase where fibre selection is becoming a more active financial decision. Cotton remains indispensable across premium and natural-fibre categories, but the widening polyester discount is changing the economics of mass-market production.

For Indian mills, the immediate opportunity is not to replace cotton, but to use cheaper polyester strategically. As long as the crude-led cost advantage persists, poly-cotton blends are likely to become an important tool for protecting margins, winning price-sensitive orders and managing raw-material volatility.
