Question

Give 1 difference between the following:-
a. Coarse and fine yarn
b. Spun and filament yarns

Answer 1

Staple fiber yarns and textured yarns normally have lower density than continuousfilament yarns made from the same fiber material. Different spinning techniques produce differentdegrees of yarn density as a result of the different patterns of fiber compactness imposed by yarntwisting and spinning 

Answer 2

Answer:

(a) Coarse yarns

Coarse yarns are more strong and have more prominent protection from stripping and cross-threading. The stature of each string is more noteworthy than the comparing fine thread so there is more material between each string making flank engagement more prominent.

Fine yarns

Fine yarns jolts are more grounded than the comparing coarse threaded electrical discharges same hardness. This is in both tension and shear because of the finely threaded bolts having a marginally bigger malleable pressure zone and minor diameter.
