Man-Made Fibres (MMF) and Technical Textiles

Man-made fibres are fibres that are made in a factory instead of being grown on a plant or taken from an animal. Polyester, nylon, acrylic and viscose are the most common examples. Technical textiles are fabrics made mainly for a job (to protect, filter, hold, heal or strengthen) and not mainly for looks or fashion.

A seat belt, a surgical mask, a fire-fighter's suit and the sheet laid under a highway are all technical textiles. Many technical textiles are made from man-made fibres, which is why the two ideas are usually discussed together.

How are fibres classified?

Every textile starts with a fibre: a thin, long thread-like strand. Fibres fall into two big families:

• Natural fibres: these come from nature. Cotton and jute come from plants. Wool comes from sheep, and silk comes from the cocoon of the silkworm.
• Man-made fibres (MMF): these are produced in factories. They are of two kinds:
• Synthetic fibres: made fully from chemicals that mostly come from crude oil and natural gas. Examples: polyester, nylon, acrylic, and elastane (also called spandex or Lycra, the stretchy fibre in sportswear).
• Regenerated (semi-synthetic) cellulosic fibres: made by taking a natural material, usually wood pulp, dissolving it with chemicals and pulling it out again as a fibre. Examples: viscose (also sold as rayon), modal and lyocell.

A simple way to remember: synthetic fibres start from oil, regenerated fibres start from wood, and natural fibres start from a plant or animal and are used almost as they are.

How is a man-made fibre made?

The basic idea is the same as making noodles in a machine. A raw material is melted or dissolved into a thick liquid. This liquid is pushed through a plate with very fine holes, called a spinneret. The thin streams that come out are cooled or hardened into long threads, called filaments. These filaments can be used as they are (filament yarn) or cut into short pieces (staple fibre) and spun like cotton.

For polyester, the two main raw materials are PTA (purified terephthalic acid) and MEG (mono ethylene glycol), both made from petroleum. Nylon is made mainly from a chemical called caprolactam, and acrylic from acrylonitrile.

Why do man-made fibres matter so much?

Worldwide, man-made fibres are now far bigger than natural ones. In 2024, polyester alone made up about 59% of all fibre produced in the world, while cotton made up only about 19% (Textile Exchange, Materials Market Report 2025). MMF has some clear advantages:

• Steady supply and price: cotton depends on rain, pests and the harvest, but a fibre plant can run all year.
• Special qualities: MMF can be made strong, stretchy, quick-drying, water-proof or fire-resistant as needed.
• Lower cost per use: polyester clothes last long and need less ironing.

The main downsides are that synthetic fibres come from fossil fuels, do not break down easily in nature, and shed tiny plastic pieces (microplastics) when washed.

India's position in MMF

India has traditionally been a cotton country. It is one of the world's largest producers of cotton, and for decades most Indian clothing and exports were cotton-based. But India's demand is changing. The Ministry of Textiles' National Household Survey 2024 (released in 2026) found that MMF and blended products now make up about 52.2% of household textile spending, against 41.2% for cotton products.

India is also among the world's largest producers of polyester and viscose. Big Indian firms make polyester (from petrochemical complexes in Gujarat and Maharashtra) and viscose. Still, India's share in the world's MMF garment trade is small compared with China, Vietnam and Bangladesh, which is why the government gives MMF special support.

What are technical textiles?

Normal textiles are chosen for comfort and appearance. Technical textiles are chosen for performance. The Ministry of Textiles groups them into 12 segments:

• Agrotech: for farming, such as shade nets, mulch films and crop covers.
• Buildtech: for construction, such as scaffolding nets and roofing fabrics.
• Clothtech: functional parts of clothing, such as zips, labels and interlinings.
• Geotech: fabrics laid in soil for roads, dams and slopes (geotextiles), to stop soil erosion and drain water.
• Hometech: in the home, such as mosquito nets, mattress and furniture fillings.
• Indutech: for industry, such as filters and conveyor belts.
• Meditech: for health, such as masks, gowns, bandages and sutures.
• Mobiltech: for vehicles, aircraft and trains, such as seat belts, airbags and tyre cords.
• Oekotech: for protecting the environment, such as oil-spill absorbers and landfill liners.
• Packtech: for packing, such as jute and plastic sacks and big bulk bags.
• Protech: for protecting people, such as bullet-proof jackets and fire-proof suits.
• Sportech: for sports, such as sports shoes, parachutes and artificial turf.

A useful trick: almost every segment name tells you its use (Medi = medical, Mobil = mobility, Geo = earth).

How has India supported this sector?

The main steps are:

• 207 HSN codes (2019): the government gave technical textiles their own trade codes. An HSN code is an international product code used in customs and GST. Before this, technical textiles were mixed with other goods, so the government could not even measure how much was made, imported or exported. More codes were added later.
• National Technical Textiles Mission (NTTM): approved by the Cabinet Committee on Economic Affairs in February 2020, with an outlay of Rs 1,480 crore, first for 2020-21 to 2023-24 and later stretched to 2025-26. It has four parts: research and development; promotion and market development; export promotion; and education, training and skilling.
• PLI Scheme for Textiles (2021): Rs 10,683 crore, aimed only at MMF apparel, MMF fabrics and technical textiles, not cotton. This was a deliberate choice to push India into the faster-growing part of the world market.
• PM MITRA Parks: seven large integrated textile parks with an outlay of Rs 4,445 crore, in Tamil Nadu, Telangana, Gujarat, Karnataka, Madhya Pradesh, Uttar Pradesh and Maharashtra, where the whole chain from fibre to garment can sit in one place.
• GST correction (2025): earlier, MMF fibre was taxed at 18%, MMF yarn at 12% and fabric at 5%. Since the raw material was taxed more than the product, money got stuck with manufacturers. This problem is called an inverted duty structure. From 22 September 2025, the GST on MMF fibre was cut from 18% to 5% and on MMF yarn from 12% to 5%.
• Export target: the government aims for technical textile exports of USD 10 billion by 2030. Exports were about USD 2.5 billion in 2022-23.

Commonly confused concepts

• Man-made vs synthetic: all synthetic fibres are man-made, but not all man-made fibres are synthetic. Viscose is man-made but not synthetic, because it comes from wood pulp, not oil.
• Viscose vs cotton: both are made of cellulose (the material that makes up plant walls), but cotton is grown as a fibre while viscose is chemically made from wood.
• Technical textiles vs MMF: MMF is a type of raw material. Technical textiles are a type of end use. A jute sack is a technical textile (Packtech) but is made from a natural fibre.
• NTTM vs PLI for Textiles vs PM MITRA: NTTM funds research, skills and market building for technical textiles. PLI pays companies for extra sales. PM MITRA builds big parks (land, power, water, common facilities).
• Filament vs staple fibre: filament is one long continuous thread; staple fibre is short pieces cut to length and then spun.

Issues, criticism and the way forward

• Raw material cost: Indian MMF raw materials like PTA, MEG and viscose fibre have often cost more than in China. Industry groups have argued that import curbs and quality-control orders on these inputs raised prices for small weavers and garment makers.
• Scale: Indian garment units are often small. Buyers abroad want huge, quick orders, which favours larger factories in China, Vietnam and Bangladesh.
• Weak research base: many high-end technical textiles (aramid fibres for bullet-proof vests, carbon fibre) are still imported. Building them needs long-term research money.
• Low awareness and standards: many Indian users do not know about geotextiles or agro-textiles. The government has been making their use compulsory in some public works and has issued quality-control orders for some products.
• Environment: synthetic fibres come from fossil fuels and release microplastics. Recycled polyester (from used plastic bottles) and better waste rules are part of the answer.
• Way forward: experts suggest cheaper raw materials, larger integrated parks, faster approvals, more research under NTTM, wider use of technical textiles in government projects and trade deals that give Indian MMF goods better access abroad.

Concepts to Know

• Fibre, yarn and fabric: a fibre is the basic strand; yarn is many fibres twisted into a thread; fabric is cloth made by weaving or knitting yarn.
• Cellulose: the natural material that forms the walls of plant cells. Cotton is almost pure cellulose; wood is also rich in it.
• Petrochemicals: chemicals made from crude oil or natural gas. PTA and MEG, used to make polyester, are petrochemicals.
• HSN code (Harmonized System of Nomenclature): a number given to each type of product, used all over the world for customs and in India for GST, so goods can be counted and taxed correctly.
• Inverted duty structure: when the tax on raw materials is higher than the tax on the finished product. The maker pays more tax on inputs than it collects on sales, so its money gets blocked.
• Microplastics: plastic pieces smaller than 5 mm. Washing synthetic clothes releases tiny fibres that end up in rivers and seas.
