M4Q1.Justify, if the fiber fineness is varied from coarser to finer what is the impact on yarn properties? (assume count spun is same)
Answer: The number of fibers in the yarn cross section will get increase, and this intern will give less mass variation (CV %), higher strength, good cover factor in the fabric, etc.
M4Q2.Explain briefly suitable method to measure fiber fineness having circular cross section.
Answer: Refer: Fiber fineness ----->Method of Measurement ---->(c) By Microscope
M4Q3.What is the relation between specific surface area and fiber diameter in air flow testing of fineness value? Explain the relation with suitable graph.
Answer: The surface area of the fibers will increase with the increase of fineness of fibers; it is due to no. of fibers will be more in particular region than coarser fiber.
M3Q4.Briefly write about the working of Fiber Diameter Analyzer with neat diagram.
Answer: Refer: Fiber fineness -----> Method of Measurement ----> (f) Light Scattering Method
M4Q5.Explain briefly suitable method to measure fiber fineness having circular cross section.
Answer: Refer: Fiber fineness ---> Method of Measurement ---> (c) By Microscope
M4Q6.Briefly write about the working of Fiber Diameter Analyzer with neat diagram.
Answer: Refer: Fiber fineness ---> Method of Measurement ---> (f) Light Scattering Method
