Which of the following fibre is made from refined plastic?

In contrast, nylon is a synthetic fibre obtained from plastics derived from petroleum. The plastic is first melted at high temperature and then forced out through a device with many holes in it known as a spinneret. Since, nylon is developed from plastic, a spinneret is needed to make nylon fibres.

Which of the following fibres is made from plastic?

Nylon- Nylon was first commercially synthesized fibre. Nylon is synthesized from coal, water and air. Nylon is very strong and its fabric is like silk. Polyester- Polyester, one of the most popular man-made fibres.

Which of the following is a synthetic fibre a cotton B acrylic C jute D wool?

Correct option- B. Explanation: Synthetic fibers are obtained from chemicals and are stronger due to strong intermolecular forces. Nylon is a synthetic fiber composed of polyamide and cotton, jute, wool are natural fibers are they are naturally obtained.

What is polyester made of Class 8?

Polyester. Polyester is manufactured from petroleum. It is a category of polymer which contain an ester group in their main chain. PET (Polyethylene terephthalate), the commonly used polyester, is made from two monomers by condensation polymerization.

Which one of the following is a synthetic fibre a nylon B Rayon C polyester D all of these?

Some natural fibres obtained from plants are cotton, jute, etc and natural fibres that are obtained from animals are wool, silk, etc. So, nylon is a synthetic fibre.

Synthetic Fibres - Introduction | Don't Memorise

Which fibre is used as artificial wool A acrylic B rayon C nylon D cotton?

Acrylic- Acrylic is a man-made fibre. Acrylic is known as artificial wool or synthetic wool because it resembles wool.

Which is a best fibre a nylon B rayon C spandex D acrylic?

Answer: (c) Nylon.

How is rayon made?

Rayon is described as a regenerated fibre because the cellulose, obtained from soft woods or from the short fibres (linters) that adhere to cottonseeds, is converted to a liquid compound, squeezed through tiny holes in a device called a spinnerette, and then converted back to cellulose in the form of fibre.

How is terylene made?

Terylene fibre was first discovered by two chemists Lanca and Shire in 1941. It is a synthetic polyester fibre which is made by a process of polymerizing ethylene glycol and terephthalic acid. The ethylene glycol and terephthalic acid are obtained from petroleum. It is widely used in textile industries.

Is polyester A fibre?

Polyester is a generalised term for any fabric or textile, which is made using polyester yarns or fibres. It is a shortened name for a synthetic, man-made polymer, which, as a specific material, is most commonly referred to as a type called polyethylene terephthalate (PET).

Which of the following is a synthetic fibre a Terrywool B Terrycot C Terylene D all of them?

Explanation: Terrycot is made up from terylene or polyester and cotton. Terylene is basically an artificial or synthetic textile fibre that is made up from polyester. Hence, in all the above three polyester is used as a monomer.

Which of the following is a cellulose Fibre a cotton B wool C Rayon D polyester?

Answer: Rayon is a synthetic fiber, made from natural sources of regenerated cellulose, such as wood and related agricultural products. It has the same molecular structure as cellulose.

Which of the following fibres are made from petroleum products a acrylic B decron C Acrylon D All of the above?

Answer: (4) All of these

Petrochemicals are the products of petroleum by which different types of fibres like nylon, polyester and acrylic all are prepared.

What is plastic synthetic fiber?

Polyester (Poly + ester) is made up of the repeating units of a chemical known as an ester. Plastic is also a sort of polymer like the synthetic fiber. Polythene (Poly + ethene) is a common example of a plastic.

What are plastic for Class 8?

A plastic is a synthetic material which can be moulded or set into desired shape when soft and then hardened to produce a durable article. Plastics are also polymers. They consist of very long molecules made by joining many small molecules together. For Ex:Polythene,Polyvinyl chloride,Bakelite,Melamine,teflon etc.

Is Terylene a plastic?

Solution : Terylene is a fibre , and not a thermosetting plastic because on heating they melt and do not show plastic property while rest options are true regarding terylene.

What is acrylic fiber made from?

Acrylic fibers are made by spinning acrylonitrile copolymers containing at least 85% acrylonitrile monomer. To produce continuous filaments, the polymer is dissolved in a solvent and extruded through spinnerets. Afterwards, the continuous filaments are washed and dried.

What fibre is terylene?

Terylene is the registered trademark of Imperial Chemical Industries Ltd., for their polyester fibre.

Is rayon made of plastic?

Yes, rayon is any type of synthetic or semi-synthetic fiber (depending on who you ask) that is made from cellulose. Because rayon fibers are made from tree and plant pulp, companies now market rayon as natural fibers.

What is polyester made of?

Polyester is a synthetic fiber, but its raw materials still come from nature. Most polyester is made out of petroleum, a natural non-renewable resource.

What is viscose silk?

Viscose is a semi-synthetic type of rayon fabric made from wood pulp that is used as a silk substitute, as it has a similar drape and smooth feel to the luxury material. The term “viscose” refers specifically to the solution of wood pulp that is turned into the fabric.

Which of the following is semi-synthetic a nylon B polyester C rayon D acrylic?

Ans. Rayon is a semi-synthetic fiber.

Which of these fibres is made of protein a wool B silk C both A and B d none of these?

Hint: As we know, silk is obtained naturally from cocoons of the larvae of the silkworm. Moreover, silk is a natural as well as a protein fibre too. So, it is a natural protein fibre. Complete step by step answer: Silk fibres are one of the examples of the natural fibres.

What are synthetic fibres Class 8?

Answer: The fibres which are produced chemically by human beings are called as synthetic fibres. Most of the synthetic fibres are obtained from coal, petroleum and natural gas. Nylon and rayon are two examples of synthetic fibres.
