The correct answer is (a), (b) and (c) only.

Key Points

(a) Z-twist
Z-twist refers to the direction of twist that resembles the letter "Z." When looking at the yarn from one end, if it twists in a direction that goes from the top left to the bottom right, it is considered Z-twist. This type of twist tends to be used in the production of many types of yarns, contributing to their strength and stability.

(b) S-twist
S-twist is the opposite of Z-twist and resembles the letter "S." If you view the yarn from one end and see that it twists from the top right to the bottom left, it is classified as S-twist. S-twist is also common in yarn production and can affect the fabric's drape and texture.

(c) Zero-twist
Zero-twist means that the fibers are not twisted at all. This results in a softer, more delicate yarn and is often used in specialty fabrics where a gentle, fluffy texture is desired. Zero-twist yarns can be more prone to fraying but are ideal for lightweight, airy textiles.

These twists are important in textile manufacturing as they influence the yarn's strength, elasticity, and appearance, ultimately affecting the quality and characteristics of the finished fabric.

The correct answer is 'Density'

Key Points

• Density:
  • Density is a secondary property of fibers, referring to the mass per unit volume of the fiber material.
  • It affects the weight and bulkiness of the textile products made from the fibers.
  • Density is crucial for applications where weight and thermal properties are important, such as in insulation or lightweight fabrics.

Additional Information

• Uniformity:
  • Uniformity refers to the consistency in the diameter and length of fibers, which is a primary property because it directly affects the smoothness and strength of the yarn and fabric.
• Cohesiveness:
  • Cohesiveness is the ability of fibers to stick together during spinning, a primary property crucial for the spinning process and yarn formation.
• Tensile Strength:
  • Tensile strength is the maximum stress a fiber can withstand while being stretched or pulled before breaking, a primary property essential for the durability and performance of the textile.

The correct answer is 'Filtering'

Key Points

• Filtering:
  • Filtering the spinning solution is a crucial step in yarn preparation as it removes impurities and ensures a consistent quality of the fiber.
  • If the solution is not properly filtered, air spaces can form within the fabric, leading to defects and reduced fabric strength.
  • Proper filtering ensures that the fibers are uniform and compact, which is essential for high-quality textile production.

Additional Information

• Bleaching:
  • Bleaching is a process used to remove the colour from fibers, yarns, or fabrics, making them white or preparing them for dyeing. It does not affect the air space in the fabric directly.
• Xanthating:
  • Xanthating is a chemical process used in the production of viscose rayon fibers. It involves treating cellulose with carbon disulfide and caustic soda. This process is unrelated to the formation of air spaces in the fabric.
• Ripening:
  • Ripening refers to the aging process of the spinning solution in the production of certain synthetic fibers. While important for fiber quality, it does not directly cause air spaces in the fabric.

The correct answer is '(A) is incorrect, but (R) is correct.'

Key Points

• Assertion (A):
  • The assertion states that it is possible to dye textiles containing fibers with different dye affinities with one solid colour using a single dye bath.
  • This is generally incorrect because different fibers often require different dye types and conditions to achieve consistent colouring.
• Reason (R):
  • The reason states that dyes having affinity for different fiber types can be used to produce one solid colour.
  • This is correct as certain dyes, like disperse dyes for synthetic fibers and reactive dyes for natural fibers, can be chosen to match the desired colour on different fiber types.
