With reference to polyethylene terephthalate, the use of which is so widespread in our daily lives, consider the following statements : 1. Its fibres can be blended with wool and cotton fibres to reinforce their properties. 2. Containers made of it can be used to store any alcoholic beverage. 3. Bottles made of it can be recycled into other products. 4. Articles made of it can be easily disposed of by incineration without causing greenhouse gas emissions. Which of the statements given above are correct ?

Lists synthetic fibres (e.g., dacron, teteron, terylene) alongside natural fibres in textile manufacture, showing synthetics are already integrated into textile production.

A student could note PET is a common polyester (like dacron/terylene) and so infer that similar production/usage practices might allow blending with cotton/wool to modify properties.

States cotton 'competes with' wool, silk, rayon, nylon and synthetic fibres, implying synthetic fibres are alternatives/co-used in the textile market.

Using basic knowledge that competition often leads to blends/variants, a student could investigate whether cotton products are blended with synthetics to gain desired traits (e.g., strength, wrinkle resistance).

Describes wool's key properties (insulation, moisture absorption, durability), which are specific attributes manufacturers might want to retain or modify by blending.

A student could consider which wool properties to enhance or protect (e.g., increase strength or wrinkle resistance) and whether adding a polyester like PET could plausibly provide those effects.

Notes mechanization of textile manufacture and broad use of fibers, indicating production processes exist that can handle large-scale fibre processing and mixing.

A student might infer that industrial spinning/weaving equipment can blend different fibre types (natural + synthetic) and so check technical sources on blending methods for PET with cotton/wool.
