The high consumption of flax for linen in the U.S. and the fact that the U.S. does not
produce any flax or linen has prompted research into the ultimate goal of re-establishing a
flax/linen industry. An improved retting method for flax stems using pectinase-rich mixtures
is developed and evaluated on a variety of fiber and seed flax samples. The method, termed
spray enzyme retting (SER), is as follows: crimp stems to enhance penetration of enzyme
formulations into the stems tissues, add chelators with enzymes in water at pH 5.0 to
improve enzyme effectiveness, spray the formulation on crimped stems to soaking, and
incubate at high humidity for several hours. Total fiber yield, collected from dried and bench
carded SER flax, and fiber strength and micronaire (modified to use 5 g of fiber) are
determined and compared for various sample types, forms, and amounts. A test of 19
samples indicates that the liquid : fiber ratio (in ml/g), after subtracting excess run-off of
enzyme formulation, is 1.86 ± 0.5. Total fiber yields are about 25 to 30% of starting crimped
weight of fiber flax stems and considerably higher for samples previously dew retted prior to
SER. Micronaire values are high (about 7-8) for bench carded samples and lower (about 4
to 5) for the finer proportion from samples cleaned through a Shirley analyzer. Depending on
the samples, fiber strengths (Stelometer) are equal to or consid erably greater than dew
retted "cottonized" flax or typical cotton fibers.
