English term

pattern of fibre strain distribution

English Tech/Engineering Engineering (general) textile engineering
Yarn density is a very
important yarn parameter, as it governs the initial non-linear deformation of the yarn as well as the
pattern of fibre strain distribution during yarn deformation, and this point will be amplified
theoretically in section 2.8.

the way the strains on the fibres are distributed as the yarn is deformed

Not sure if that makes it any clearer.

It means the way the fibres are put under tension, which may elongate, deform or modify them if the tension rises above a certain level.
Note from asker:
Thank you...what is the meaning of strain here: elongation, deformation or modification of the fibers as a result of applied stress?

Thank you.
agree Ken Cox : 'strain' here is a well-defined engineering term and refers to any change in dimension or shape of a solid material (including deformation and elongation) as a result of stress

sone strains are curly, some are straight and others are twisted

Yarn is made up of interconnecting fibers to create one length, each fiber is a strain, a different thickness, or other, and where they connect the pattern causes a knot when the strains are very different when they are joined.
I will look it up for you but, I am sure.
straight fiber strains are a round fiber
gentle wavy/ curling fibers are oval
and very curly fiber strains triangular in shape

Below you can see the differing fiber construction from different strains.

Strain= where it comes from. Sheep (different breeds), Goat, alpaca, hemp even polymer fibers are strains due to their different compositions.

Ken, They are talking about "the pattern of fiber strain distribution" not the strain put on the fiber under load. as seen in image..http://www.p2pays.org/ref/04/03812/Image63.gif
the different fiber strains are set in a patten and distributed according to dimensional sizes, "Yarn density is a very important yarn parameter, as it governs the initial non-linear deformation of the yarn" If the wrong fiber strain is in the wrong place the yarn parameter will be knotty and the yarn density will be compromised.
