With reference to polythylene terephthalate, the use of which is so widespread in our daily lives, consider the following statements: 1. Its fibres can be

1. A. 1 and 3
2. B. 2 and 4
3. C. 1 and 4
4. D. 2 and 3

Answer: A

Explanation

Polyethylene terephthalate (PET or PETE), a strong, stiff synthetic fibre and resin and a member of the polyester family of polymers. PET is spun into fibres for permanent-press fabrics and blow- molded into disposable beverage bottles. Statement 1 is correct: They are often used in durable-press blends with other fibres such as rayon, wool, and cotton, reinforcing the inherent properties of those fibres. Statement 2 is not correct: Plastic packaging is dangerous to human health and the country liquor and country made foreign liquor cannot be sold in such bottles. Statement 3 is correct: PET bottles are made of one of the few polymers that can be recycled into the same form – a new beverage bottle – again and again. During the process the PET is generally blended in a ratio of virgin to recycled, to give strength to the material for use in a new product. Some other everyday items recycled plastic bottles can be made into are: Plastic packaging, Clothing and shoes, Carpets and soft furnishings, Furniture, Automotive parts etc. Statement 4 is not correct: Globally, in this year alone, researchers estimate that the production and incineration of plastic will pump more than 850 million tonnes of greenhouse gases into the atmosphere. Producing a 16 oz. PET bottle generates more than 100 times the toxic emissions to air and water than making the same size bottle out of glass.
