1.
Which of the following yarns of same fineness is supposed to have highest strength?
Correct Answer
B. Ring spun yarn
Explanation
Ring spun yarn is supposed to have the highest strength among the given options. This is because ring spinning is a method that produces a tightly twisted yarn, resulting in a stronger and more durable yarn compared to other types. Carded yarn, woollen yarn, and novelty yarn are produced using different spinning techniques that typically result in a less tightly twisted yarn, making them comparatively weaker in terms of strength.
2.
Novelty yarns are used for:
Correct Answer
D. Both
Explanation
Novelty yarns are used for both strength and aesthetics. These types of yarns are designed to have unique textures, colors, and patterns, making them visually appealing and adding visual interest to the fabric or garment they are used in. At the same time, they are also engineered to have good tensile strength, making them suitable for various applications where durability is required. Therefore, novelty yarns serve the purpose of enhancing the appearance of the final product while also providing the necessary strength.
3.
Example of indirect count is:
Correct Answer
A. Cotton Count
Explanation
Indirect count refers to a method of measuring the fineness or thickness of a textile material. Cotton count is one such example of indirect count, which is a system used to measure the thickness of cotton yarn. It is calculated by determining the number of hanks of yarn that weigh one pound. The higher the cotton count, the finer and thinner the yarn. This measurement is commonly used in the textile industry to determine the quality and characteristics of cotton yarn.
4.
2/40s yarn is:
Correct Answer
D. Plied yarn
Explanation
A plied yarn is made by twisting two or more single yarns together. This process increases the strength and durability of the yarn. In this case, the yarn is described as "2/40s", which means it is made up of two strands of yarn with a count of 40. Therefore, the correct answer is plied yarn.
5.
Cotton yarn can be classified as ______________ yarn only.
Correct Answer
Spun
Explanation
Cotton yarn can only be classified as spun yarn because spun yarn is made by twisting or spinning fibers together, and cotton fibers are spun to create cotton yarn. Other types of yarn, such as filament yarn, are made from long continuous filaments and are not applicable to cotton yarn. Therefore, spun is the correct classification for cotton yarn.
6.
In between cotton and polyester, monofilament yarn is possible with ______________ only.
Correct Answer
Polyester
Explanation
Monofilament yarn refers to a single, continuous strand of yarn. Cotton does not have the properties to be spun into a monofilament yarn, as it is a natural fiber with shorter staple lengths. On the other hand, polyester, being a synthetic fiber, can be extruded into a continuous filament, making it suitable for monofilament yarn production. Therefore, polyester is the only option that can be used to create monofilament yarn.
7.
In indirect count, a higher number of yarn fineness denotes a ___________ yarn.
Correct Answer
Finer
Explanation
In indirect count, a higher number of yarn fineness denotes a finer yarn. This means that the yarn has a smaller diameter or thickness. A finer yarn is generally considered to be of higher quality as it is more delicate and can be used to create finer and more intricate designs in textiles. It is also often associated with a softer and smoother texture.
8.
is a thick and thin yarn with randomly spaced soft, lofty portions produced by irregular intervals of twist and lack of twist in the yarn formation.
Correct Answer
Slub yarn
Explanation
Slub yarn is a type of yarn that has both thick and thin sections, which are created by irregular intervals of twist and lack of twist during the yarn formation process. These irregularities result in randomly spaced soft and lofty portions in the yarn.
