" Which of the following are primary properties of textile fibers?
A. Tenacity
B. Cohesiveness
C. Luster
D. Uniformity
Choose the correct answer from the options given below:

Correct option is A

1. (B) Cohesiveness:
· Cohesiveness is the ability of fibers to cling together during processes like spinning. This property is crucial in the formation of strong and uniform yarns. It ensures that fibers can interlock, making it a primary property for textile applications, particularly in yarn formation.
· Cohesiveness: Important for yarn formation, especially in shorter fibers like cotton, where the ability to cling together is crucial.
2. (D) Uniformity:
· Uniformity describes the consistency in fiber structure, such as diameter or length. It plays a significant role in the processing and final quality of textiles. Fibers with uniform characteristics are easier to work with and produce better-quality fabrics, making it a primary property.
· Uniformity: Ensures consistency in fiber behavior during spinning and weaving, leading to better-quality fabrics.
Information Booster:
Primary properties of textile fibers include those fundamental characteristics that impact how the fiber behaves during processing and in final textile products. These properties, like cohesiveness and uniformity, are essential for determining the fiber's suitability in fabric and yarn production.
Additional Knowledge:
(A) Tenacity:
· Tenacity refers to the fiber's strength and its ability to withstand tension without breaking. While important, it is considered a mechanical property rather than a primary one. It is essential for determining how a fiber performs under stress but does not define the fiber's fundamental characteristics.
· Tenacity: A key mechanical property that contributes to the durability of the fiber but is not considered a primary property in basic fiber classification.
(C) Luster:
· Luster refers to the shine or glossiness of a fiber, which is determined by how light reflects off its surface. While luster adds to the visual appeal of textiles, it is an aesthetic or secondary property and not considered a primary property in the context of fiber performance.
· Luster: Although important for aesthetic purposes, it is not a fundamental requirement for all textile fibers.
