Assignment on manufatcturing industries


Q. What are agrobased industries?
A. Industries which use agriculture as their raw material are called agro based industries.For example—cotton, jute, silk, wollen textile, sugar and edible oil.
Q. How can we say that textile industry occupies a unique position in the Indian economy?
A. It has a unique position because:
a) It contributes significantly to the industrial production-14%
b )Employment generation—35 million persons; second largest after agriculture.
c) Brings in foreign exchange earnings—about 24.6%
d) Contributes 4% towards GDP.
e) The only industry which is self-reliant and complete in the value chain ie., from raw material to value added products.
Q. Discuss the growth of cotton textile industry in India.
A. In ancient India cotton textiles were produced with hand spinning and handloom weaving techniques.
--After the 18th century power looms came into use.
--The first textile mill was established in 1854.
--During world wars Indian cloth was in demand in UK hence the development of textile industry in India.
--Today there are 1600 cotton and human made fibre textile mills in India.-80% in the private sector and the rest in the public & cooperative sectors. There arer also thousands of small factories with 4 to 10 looms.
--As this industry has close links with agricultural and provides a living to farmers, cotton boll pluckers, workers engaged in ginning, spinning, weaving, dyeing, designing, packaging, tailoring and sewing.
--By creating demands it supports many industries such as chemicals, dyes, mill stores, packaging materials & engineering works.
--Spinning centers are centralized in Maharashtra, Gujrat, Tamil Nadu, weaving is highly decentralized to incorporate traditional designs.
--Hand spun khadi provides large scale employment to weavers in their homes as cottage industry.
--India exports yarns to Japan, U.S.A., Nepal, Singapore, Sri Lanka & African countries.
--India has second largest installed capacity of spindles in the world & we share one-fourth of world trade of cotton yarn .
Q. What are the major drawbacks or the problems faced by the cotton textile industry?
A. Our weaving, knitting and processing units can not use much of high quality yarn produced in the country thus low quality fabric.
b)Our trade in garments is only 4% of the world’s total.
c) There are large and modern factories but most of the production is in fragmented small units which cater to local markets. This mismatch is the major drawback of this industry.
Therefore our spinnres export yarn while our apparel/garments manufacturers import fabric.
d) Erratic power supply
e) Machinery needs to be upgraded in weaving, processing sectors.
f) low out put of labour.
g) Stiff competition from the synthetic fibre.
