What are blended fibres?

  1. Mixture of two natural fibres

  2. Mixture of two synthetic fibre

  3. Mixture of natural and synthetic fibres

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Blended fibres are made by combining various fibres to enhance the property of the product. For eg: spandex and cotton is a natural mix for sports clothing and undergarments to improve stretching properties and prevent odour. A blended fabric helps overcome the disadvantages of natural and synthetic fibre.

Multiple choice

Silk is produced from Caterpillar larvae

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silk is a natural protein fiber, some forms of which can be woven into textiles. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm.

Multiple choice

Materials that are formed naturally are

  1. Biodegradable

  2. No biodegradable
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Materials formed naturally (like plant matter, wood, paper, food waste) are biodegradable because microorganisms have evolved to break them down through natural processes. Synthetic materials typically lack this property unless specifically engineered. 'No biodegradable' is grammatically incorrect.

Multiple choice

This bag is made of artificial leather.

  1. modern

  2. synthetic

  3. new

  4. natural
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Synthetic is the standard term for materials that are man-made or artificial. Modern, new, and natural do not carry the same meaning as artificial in this context.

Multiple choice zoology sustainable agriculture microbes and farming biopesticide environmental protection

Refer to the given dichotomous key and select the correct option.
I.   (a) Fibre obtained from natural sources - Go to II
     (b) Fibre obtained from chemical, - K
II.  (a) It is a cellulosic fibre - Go to III
     (b) It is a protein fibre. - Go to IV
III. (a) It is obtained from leaves. - L
     (b) It is obtained from seeds.
IV. (a) It is obtained from mammals. - N
     (b) It is obtained from an insect. - O

  1. Fabrics fibres K and N could be water proof.

  2. When fibres L and M are burnt separately they give smell of burning paper and burning hair, respectively.

  3. Fibre L is separated from leaves by retting process whereas from seeds by ginning process.

  4. N can be obtained from the same animal repeatedly whereas O can be obtained from source animal only once in its lifetime.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fabrics fibers K and N are usually laminated to or coated with a waterproofing material such as rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, fluoropolymers, and wax

So, the correct option is 'Fabrics fibers K and N could be waterproof'.

Multiple choice dyes dyes and pigments chemistry in daily life applied chemistry chemistry

Different dyes are used for dyeing different materials. Which of the following statements is false?

  1. Nylon can be dyed with acid dyes

  2. Cotton can be directly dyed with malachite green

  3. Terylene is mainly dyed with disperse dyes

  4. Polyacrylonitrile can be dyed with basic dyes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The color of the wool cloth dyed directly by dipping in hot solution of malachite green dye is fast. The color of cotton cloth dyed directly (without using mordant) by dipping in hot solution malachite green is not fast to washing and is of low intensity.

Vat dyes are essentially incapable of dyeing:

  1. fiber

  2. stone

  3. wood

  4. none of the above
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

Vat dyes are essentially insoluble in water and incapable of dyeing fibers directly. However, reduction in alkaline liquor produces the water-soluble alkali metal salt of the dye, which, in this leuco form, has an affinity for the textile fiber. Subsequent oxidation reforms the original insoluble dye. The color of denim is due to indigo, the original vat dye.

Hence option A Is correct.









Multiple choice dyes dyes and pigments chemistry in daily life applied chemistry chemistry

Which type of dyes are not used to dye nylon and polyester fibres?

  1. Vat dyes

  2. Basic dyes

  3. Disperse dyes

  4. Insoluble azo dyes
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Vat dyes are not used to dye nylon and polyester fibres but used to dye cotton fibres. 


Basic dyes disperse dyes and insoluble azo dyes are used to dye nylon and polyesters.
