Which of the following fibers has the highest tensile strength?

  1. Cotton

  2. Wool

  3. Nylon

  4. Polyester


Correct Option: C
Explanation:

Nylon is a synthetic fiber known for its exceptional tensile strength, making it resistant to stretching and breaking.

In the context of yarn manufacturing, what is the process of twisting fibers together called?

  1. Spinning

  2. Weaving

  3. Knitting

  4. Dyeing


Correct Option: A
Explanation:

Spinning is the process of twisting fibers together to form a continuous yarn, which is a fundamental step in yarn manufacturing.

Which weave pattern is characterized by a series of parallel warp and weft yarns interlacing at right angles?

  1. Plain Weave

  2. Twill Weave

  3. Satin Weave

  4. Jacquard Weave


Correct Option: A
Explanation:

Plain weave is the simplest and most common weave pattern, where warp and weft yarns interlace at right angles, creating a basic and balanced fabric structure.

What is the purpose of singeing in textile processing?

  1. Removing impurities

  2. Improving fabric luster

  3. Increasing fabric strength

  4. Reducing fabric shrinkage


Correct Option: A
Explanation:

Singeing is a process that involves passing a fabric through a flame to remove surface fibers, impurities, and protruding yarns, resulting in a smoother and cleaner fabric surface.

Which test method is commonly used to determine the colorfastness of textiles to light?

  1. Abrasion Resistance Test

  2. Tensile Strength Test

  3. Colorfastness to Light Test

  4. Pilling Resistance Test


Correct Option: C
Explanation:

The Colorfastness to Light Test is specifically designed to assess the resistance of textiles to fading or color change when exposed to light, ensuring the durability of colors in various lighting conditions.

What is the primary function of a sizing agent in textile manufacturing?

  1. Improving fabric drape

  2. Increasing fabric strength

  3. Reducing fabric shrinkage

  4. Enhancing fabric color


Correct Option: B
Explanation:

Sizing agents are applied to yarns or fabrics to increase their strength, improve weaving or knitting efficiency, and reduce yarn breakage during weaving or knitting processes.

Which of the following factors primarily determines the count of a yarn?

  1. Fiber length

  2. Fiber diameter

  3. Twist per inch

  4. Yarn strength


Correct Option: B
Explanation:

Yarn count, typically expressed in units like Ne or Tex, is primarily determined by the fiber diameter, as finer fibers result in higher yarn counts.

What is the purpose of a reed in a weaving loom?

  1. Controlling fabric width

  2. Separating warp yarns

  3. Inserting weft yarns

  4. Beating up the weft


Correct Option: B
Explanation:

The reed in a weaving loom is responsible for separating the warp yarns and maintaining the desired spacing between them, ensuring the proper interlacing of warp and weft yarns.

Which of the following is a common method for printing designs onto fabrics?

  1. Screen Printing

  2. Digital Printing

  3. Embroidery

  4. Heat Transfer Printing


Correct Option: A
Explanation:

Screen printing is a widely used method for printing designs onto fabrics, involving the transfer of ink through a mesh screen onto the fabric surface.

What is the primary purpose of a tenter frame in textile finishing?

  1. Drying fabrics

  2. Stretching fabrics

  3. Sanforizing fabrics

  4. Calendering fabrics


Correct Option: B
Explanation:

A tenter frame is used in textile finishing to stretch fabrics in both warp and weft directions, ensuring dimensional stability and preventing fabric distortion.

Which of the following is a common method for testing the abrasion resistance of textiles?

  1. Martindale Abrasion Test

  2. Pilling Resistance Test

  3. Tensile Strength Test

  4. Colorfastness to Light Test


Correct Option: A
Explanation:

The Martindale Abrasion Test is widely used to assess the resistance of textiles to wear and abrasion, simulating the effects of repeated rubbing and friction.

What is the primary function of a loom in textile manufacturing?

  1. Spinning yarns

  2. Twisting fibers

  3. Weaving fabrics

  4. Knitting fabrics


Correct Option: C
Explanation:

A loom is a machine used in textile manufacturing to weave fabrics by interlacing warp and weft yarns, creating a structured and durable fabric.

Which of the following is a common method for testing the tensile strength of textiles?

  1. Martindale Abrasion Test

  2. Pilling Resistance Test

  3. Tensile Strength Test

  4. Colorfastness to Light Test


Correct Option: C
Explanation:

The Tensile Strength Test is commonly used to determine the resistance of textiles to breaking under tension, measuring the maximum force a fabric can withstand before breaking.

What is the purpose of a back-coating process in textile manufacturing?

  1. Improving fabric drape

  2. Increasing fabric strength

  3. Reducing fabric shrinkage

  4. Providing a barrier to moisture


Correct Option: D
Explanation:

Back-coating is a process in which a coating material is applied to the back of a fabric to provide a barrier against moisture, making it water-resistant or waterproof.

Which of the following is a common method for testing the pilling resistance of textiles?

  1. Martindale Abrasion Test

  2. Pilling Resistance Test

  3. Tensile Strength Test

  4. Colorfastness to Light Test


Correct Option: B
Explanation:

The Pilling Resistance Test is specifically designed to assess the resistance of textiles to the formation of pills or small balls of fibers on the fabric surface.
