Staple Yarn Processing Flashcards
what processes are involved in the blowroom?
bale laydown, opening and cleaning, and carding
what is the purpose of bale laydown?
blending
what is the output of bale laydown?
clumps of fibers
what is pneumatics?
components of the blowroom are linked by tubing and the fibers are transported using air steam
what is a bale opener?
pulls tuffs of fibers from the bales
what is a horizontal bale opener?
most common and goes horizontally over top
what is an HVI?
high volume instrumentation, does standard measurements of fiber length, uniformity, stength, finess, maturity, color and trash
what is AFIS?
Advanced fiber infromation system, used to rapdily evalute fiber length, fiber fineness and nep content in loose stock fiber and slivers
where are opposing spikes used?
in the opening process
what is the purpose of beating?
beater and grid bar is for opening and cleaning
if the distance between the grid bar and beater decreases, opening and cleaning _ and Damanging _
increases, increases
if the distance between neighboring grid bars increase, opening and cleaning _ and waste_
increases, increase
if cleaning angle decreases, opening cleaning and damanging _ and holding fibers_
increases, decreases
if mounting angle decreases, opening, cleaning damanging_ and waster_
increases, increases
why is air control critical for grid bars?
not enough-trash will be left
too much-dust will blow back to fiber
