Fibre to fabric Class 6

Polyester is a synthetic fiber made from petroleum-based chemicals, whereas silk, cotton, and wool are natural fibers derived from animals or plants.

Cotton is a breathable, absorbent natural fiber that allows air to circulate, making it ideal for keeping cool in hot summer weather.

Cotton fibers are harvested from the cotton plant, then cleaned, spun into yarn, and woven into fabric to create cloth.

To extract silk, the cocoons are boiled to kill the pupa and loosen the sericin, which allows the long, continuous silk filament to be unwound.

The silk worm spins a cocoon around itself during the pupa stage of its life cycle. This is the stage where the silk is harvested.

Wool is obtained from the fleece of sheep (or other animals), and silk is produced by the larvae of silk moths, making both animal-derived fibers.

The silk fiber is produced by the silk worm as a liquid secretion from its glands, which hardens into a cocoon. The silk is harvested from this cocoon.

Both silk and wool are composed primarily of proteins (fibroin in silk and keratin in wool), making them protein fibers.

Silk worms are highly specialized and feed exclusively on the leaves of the mulberry tree.

The process of sericulture, or silk production, was discovered and developed in Ancient China thousands of years ago.

Cotton is a natural fibre derived from the cotton plant. Nylon, Viscose, and Elastane are all man-made or synthetic fibres.

Heat is used to set pleats in fabrics, often in combination with pressure, but heat is the primary agent that alters the fibre structure to hold the shape.

Cotton/polyester is a fibre blend that combines natural cotton with synthetic polyester, giving the benefits of both materials. Rayon, silk, and nylon are each single fibres, not blends. The question has a grammatical error ('examples' should be 'example').

Linen, hemp, and rubber are plant-based (vegetable) fibres. Alpaca is an animal-based fibre, making it the correct choice for NOT being a vegetable fibre.

Fabrics can be created through various methods such as weaving, knitting, and felting. Therefore, the statement is true.

Fibres are the basic units or raw materials used to spin yarns, which are then used to make textiles and clothes.

Nylon is a synthetic (man-made) polymer, whereas wool, metallic (natural mineral), and sisal are considered natural fibres.

A filament fibre is a very long, continuous strand of fibre, as opposed to staple fibres which are short.

A fibre blend combines two different fibres. Silkworm/cocoon is not a blend; it is the source and the life stage of the natural silk fibre.

Protein fibres are composed of natural polymers of amino acids, which are derived from animal sources like wool or silk.

Jute is a natural plant fibre obtained from the jute plant. Nylon and polyester are synthetic fibres made from petrochemicals. 'Ryan' appears to be a misspelling of 'rayon', which is a semi-synthetic fibre made from chemically processed wood pulp. Jute is the only fully natural option.
