Which of the following is a common method for recycling polyester textiles?

  1. Mechanical Recycling

  2. Chemical Recycling

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Mechanical recycling involves shredding and melting polyester textiles to create new fibers or products, reducing the need for virgin materials.

What is the primary goal of closed-loop recycling in the context of textiles and fabrics?

  1. Producing new textiles from recycled materials

  2. Reducing the amount of waste generated

  3. Eliminating the use of virgin materials

  4. Increasing the lifespan of textiles


Correct Option: C
Explanation:

Closed-loop recycling aims to create a circular economy where textiles are repeatedly recycled and reused, minimizing the need for extracting and processing raw materials.

Which technology involves breaking down textile fibers into their chemical components for reuse?

  1. Mechanical Recycling

  2. Chemical Recycling

  3. Biological Recycling

  4. Thermal Recycling


Correct Option: B
Explanation:

Chemical recycling employs chemical processes to depolymerize textile fibers, enabling the recovery of monomers or other valuable chemicals for use in new products.

What is the primary benefit of using recycled textiles in the production of new fabrics?

  1. Reduced production costs

  2. Improved fabric quality

  3. Enhanced sustainability

  4. Increased fabric durability


Correct Option: C
Explanation:

Using recycled textiles reduces the demand for virgin materials, conserves natural resources, and minimizes waste, contributing to a more sustainable textile industry.

Which of the following is a common challenge associated with recycling textiles made from blended materials?

  1. Difficulty in separating different fibers

  2. Lower quality of recycled fibers

  3. Increased energy consumption

  4. Reduced recyclability of the fabric


Correct Option: A
Explanation:

Separating different fibers in blended textiles can be challenging, affecting the quality and efficiency of the recycling process.

What is the term used to describe the process of converting textile waste into new fibers or materials?

  1. Upcycling

  2. Downcycling

  3. Recycling

  4. Composting


Correct Option: C
Explanation:

Recycling refers to the process of transforming textile waste into new materials or products, aiming to reduce waste and conserve resources.

Which of the following is an example of a mechanical recycling technology for textiles?

  1. Hydrolysis

  2. Pyrolysis

  3. Melt Spinning

  4. Gasification


Correct Option: C
Explanation:

Melt spinning is a mechanical recycling process that involves melting textile fibers and extruding them through spinnerets to create new fibers.

What is the primary advantage of using recycled cotton fibers in textile production?

  1. Reduced water consumption

  2. Enhanced fabric breathability

  3. Improved fabric strength

  4. Lower production costs


Correct Option: A
Explanation:

Using recycled cotton fibers significantly reduces water consumption compared to producing virgin cotton, contributing to water conservation efforts.

Which of the following is a common method for recycling wool textiles?

  1. Mechanical Recycling

  2. Chemical Recycling

  3. Biological Recycling

  4. Incineration


Correct Option: A
Explanation:

Mechanical recycling is commonly used for wool textiles, involving shredding and reprocessing the fibers to create new wool products.

What is the term used to describe the process of converting textile waste into energy?

  1. Pyrolysis

  2. Gasification

  3. Incineration

  4. Hydrolysis


Correct Option: C
Explanation:

Incineration involves burning textile waste to generate energy, although it is generally considered less sustainable than other recycling methods.

Which technology involves using enzymes to break down textile fibers into their constituent components?

  1. Mechanical Recycling

  2. Chemical Recycling

  3. Biological Recycling

  4. Thermal Recycling


Correct Option: C
Explanation:

Biological recycling employs enzymes or microorganisms to degrade textile fibers into simpler compounds, enabling the recovery of valuable materials.

What is the primary challenge associated with recycling textiles made from natural fibers?

  1. Difficulty in separating different fibers

  2. Lower quality of recycled fibers

  3. Increased energy consumption

  4. Reduced recyclability of the fabric


Correct Option: B
Explanation:

Natural fibers, such as cotton and wool, can undergo degradation during recycling processes, resulting in lower quality recycled fibers compared to virgin materials.

Which of the following is an example of a chemical recycling technology for textiles?

  1. Hydrolysis

  2. Pyrolysis

  3. Melt Spinning

  4. Gasification


Correct Option: A
Explanation:

Hydrolysis is a chemical recycling process that involves breaking down textile fibers using water or acids to produce monomers or other valuable chemicals.

What is the term used to describe the process of converting textile waste into compost?

  1. Upcycling

  2. Downcycling

  3. Recycling

  4. Composting


Correct Option: D
Explanation:

Composting involves breaking down textile waste into organic matter through the action of microorganisms, creating a nutrient-rich soil amendment.

Which technology involves heating textile waste in the absence of oxygen to produce valuable chemicals or fuels?

  1. Hydrolysis

  2. Pyrolysis

  3. Melt Spinning

  4. Gasification


Correct Option: B
Explanation:

Pyrolysis is a thermal recycling process that involves heating textile waste in the absence of oxygen to produce valuable chemicals or fuels.
