Indian VSF Industry
Viscose IS the first man-made fiber to be produced in India. Viscose fiber production is mainly concentrated In Asia which contributes to more than 51% of the world’s production. The major players in Viscose fiber production are China, India, Indonesia, Taiwan, Germany, Austria, etc. India Stands as one of the major Producers of Viscose staple fiber.
There are only two players in India, namely Grasim Industries Ltd and SIV industries Ltd. Grasim Industries commenced production in 1954 and SIV Industries Ltd in 1961, From a modest beginning of about 50,(‘000)Mtons per annum of Man-made Fibre & Filaments in India, it has grown over a period & in ‘94.‘95, it has recorded production of 887(‘000) Mtons which is nearly 17 Times growth. This fiber was initially expected to be a replacement for cotton. However, with the market trends & changing fashion, Pure Viscose spun yarn fabrics are being popular, and “Erode” in South India is the hub of Pure Viscose weaving and processing. Fabrics produced will find usage in printing & dyeing for various end uses.
In ’70s when there was an acute shortage of cotton, the Government of India made it compulsory that at least 10% of Viscose should be blended with cotton. India being a tropical country, with the arrival of Polyester, Viscose friends a blending Partner and Polyester-Viscose which IS unique to India have found innumerable usage in Suiting, Shirtings and Dress materials. With the rapid developments of the Viscose market, in the present Situation, Viscose has been recognized as a fiber by itself and in India Viscose is no longer dependent on the up and downs of the Cotton Market.
VSF Exports of India
Viscose spun yarn and the fabrics made thereof, forms an important Segment in the export earnings of India. Pure Viscose spun yarn exports which were Rs. 200 million in (‘90-‘91) have shown a remarkable increase of 7 times to Rs. 1400 million (40million US $) in (‘95’96). During the same period, Polyester- Viscose Yarn has increased from Rs.293 million to ‘Ps. 2040 million. (58 million US $). The export of fabrics made of Viscose spun yarn and polyester/viscose spun yarn has also been steadily increasing and in the year (‘94.‘95) the export of the above fabrics accounted for Rs.2502.3 million (71.49 million US$). In India, there is a good potential in improving the export of Viscose-based items and with the encouragement from the Government of India, heavy capital investment in spinning, weaving, processing, and garment manufacture, the exports will scale new heights.
Industry Entry Barriers
The VSF industry continues to remain highly concentrated due to the following reasons :
- New players were unable to enter the industry in the 1980s due to government licensing issues. In the 1990s, no new players set up capacities, given the stringent environmental laws and conditions that the new VSF plants had to conform to.
- Any new entrant needs to make arrangements for an adequate and reliable supply of wood pulp. Arrangements would have to be either through captive facilities or long-term import contracts.
India’s Viscose Production Capacity
The past few decades have witnessed predominant use of natura1 cellulose from wood pulp to create a very wide range of Viscose fiber. India accounts for nearly 10% of the World’s VSF Capacity. At present installed capacity in India is 223.9 (‘000) M Tons per annum with M/s.Grasim Industries Ltd has an installed capacity/ of 184.9 (‘000) M Tons per annum worth plants at Nagda, Harihar & Mavoor. MIS. SIV Industries Ltd with an installed capacity of 38.95 (‘000) MTons per annum accounts for 18% of India’s Capacity and the plant is located at Sirumugai in Tamil Nadu, South India. Both the manufacturers have ambitious expansion programs.
The total capacity in India is likely to reach a level of 338.2 (‘000) Mtons per annum by 2000 AD. The demand for Viscose is increasing year after year due to its specific properties like high absorbency & better dye uptake.

Trends in Usage
Viscose Staple Fibre produced in India finds an outlet in pure spinning which is converted into fabrics for both dyeing and printing qualities and is characterized by ease of dyeing, good absorbency, rich and full dying properties, and is mainly exported. Viscose, as an excellent fiber for blending, has an outstanding future both in clothing and increasingly In the Nonwoven and hygiene sectors. In blended yarns, viscose staple fiber is popular in Polyester blends. This is mainly because of the hygroscopic property of Viscose and its clean nature. It also has the advantage of staple tut length and ease in spinning on a cotton spinning System.
Hence, viscose will serve as a major complementary fiber. Although the nonwoven Segment imports infancy in India. there will be a demand for absorbent fibers in various fields & nonwovens like personal hygiene, wipes, medical applications, disposables, and filter industry Quality has become an increasingly important distinguishing feature.
Recently, there is a rise in the manufacture of fine denier fibers. The Change In market behavior In the fine denser area exerts a direct influence on process control in viscose manufacture. Parallel to the development in the synthetic fiber area, the shift of market shares in favor of finer deniers in the recent past took place at an extreme Speed. This represents a threat which is explained by the decrease in linear production on one hand and on the other hand, the sensitivity of fine denier fibers towards the production process leading to a drop in quality. This has prompted manufacturers to narrow the process Parameters and maintain effective process control using electronic control devices.
Challenged faced by the Indian Viscose Industry
Viscose Industry is basically highly capital Intensive and this makes it unviable for new entries and hence makes expansion more sensible. The capital cost in India is very high and the rising cost of production makes it difficult to gain a foothold in the international market.
The cost of energy is high due to the low plant load factor and excessive transmission losses. Pulp cost is another major cost component that leaves the manufacturers with no other option but to modify the infrastructure and technology to suit the location for feasibility and attain a competitive edge. The Problem of pollution in the Pulp and Viscose industry needs to be analyzed carefully since the pollution control is highly capital intensive and also results in high running costs.
In India, the problem of pollution is well recognized and the manufacturers are making large investments in this direction. India is carefully watching the latest developments in solvent spinning technology and very soon, manufacturers may opt for this based on the viability.
Alternate Raw-materials for Viscose Manufacturing
Since the beginning of Viscose manufacture, renewable forest wood such as Eucalyptus, Pines Paula, Wattle, and Bamboo has been the major raw material for wood pulp manufacture in India. Nonavailability and high costs have prompted producers to look for alternatives, There is considerable headway in using green jute and Biogases as a substitute for wood. These are agricultural or industrial byproducts and India being the second largest Producer of Jute, there is abundant availability Use of these raw materials also prevents deforestation and hence aids in preserving ecology. Trials in developing hybrid varieties of eucalyptus grown in the plains have also been successful.
Viscose fiber industry technology development direction
With the development of science and technology of modern society and people return to nature and environmental awareness enhancement, viscose fiber with its complete varieties, excellent properties, more and more application industry, and consumers. Its application scope has been expanded from traditional industries to clothing, adornment, health and industrial products, etc. But viscose fiber production with other chemical fiber production, there exist problems of environmental protection. In addition, viscose process of production equipment and also too multifarious, the equipment investment is high. Therefore only in solving these problems, under the premise of viscose fiber industry can more quickly develop healthily.
Viscose fiber industry technology development direction of roughly can be summarized as the following several aspects:
- reduce the pollution of the environment, development of new spinning cellulose fiber manufacturing system.
- production process rationalization and optimization.
- strengthen the basic theories of viscose fiber.
- the development of new technology, expand the pulp pulping sources of the raw materials.
- to improve the existing fibers with a special performance, the development of new varieties.
The price of Viscose Staple Fibre was on an upward trend since the start of 2010-11, backed by rising wood pulp prices and supplemented by firm cotton prices. Although high prices dented the domestic demand for VSF in 2010-11, manufacturers kept prices firm, drawing support from an unprecedented rise in cotton prices. VSF prices reached an all-time high of ₹ 155 per kg in 2011.
Viscose staple fiber market followed a downward trend and prices went down due to sluggish demand from the downstream market in the Chinese domestic market. The viscose staple fiber market remained weakened due to a sluggish market outlook during the second half. Viscose staple fiber prices moved down triggered by the rumors about low price product availability in the market during the period.

The rapid increase in demand for fibers in the coming years will require major expansions in the capacities of fiber production. This situation will cal1 for expansion In the man-made fiber sector as natura1 fibers may not be able to address the requirement. Synthetics will certainly grow but will require a good blending component. Viscose will have a strong Position in the future as an alternate raw material because of:
- Growing demand for absorbent fibers
- Renewable raw material sources
- Excellent for blending
- Niche fiber in fashion design
- Excellent dyeing and comfort characteristics.
In the future, the market demand for cellulosic fiber and yarn will continue to be buoyant due to the positive physical properties of the fiber. The main reason behind this is the constant increase in Viscose productivity paralleled by the reduction in average denier acting as a guarantee towards Viscose industry’s continued importance in the next century. The quality of the product and the economic production of the same and necessary measures taken regarding environmental protection will a play crucial role in the development of viable solutions for the long term. As an important raw material with unique properties, Viscose has all the necessary strengths to reign in the future in the Indian Textile Industry.
