PRE WASHED
Pre-Washed helps minimize shrinkage, however there may be a slight shrinkage with the
first wash.
PRE SHRUNK
Pre-Shrunk is generally is used incorrectly to describe that it will not shrink further
when laundered, however all cottons (all uniforms) will continue to shrink depending on
water temperature and washes. Shrinkage will vary with all uniforms.
SHRINKAGE
Most uniforms will shrink, some more than others. For the uniforms that shrink, use of a
dryer will affect the overall shrinkage. Depending on the uniform and washing procedures,
the uniform could shrink anywhere from 2-5 inches on the sleeve. The cotton used in
production of a uniform will determine shrinkage, fit and softness.

Wash Jacket and pants in cold water only! Cold
water will remove blood stains and hot water will set them. DO NOT USE BLEACH , as bleach will eat into the fabric and weaken it. Drip dry. Hot
tumble drying is not recommended because the tumbling in the dryer will fray the
fabric over time. 100% cotton will shrink in Hot Water or use of a Dryer.
REVERSIBLE AND BLUE UNIFORMS
1: Turn the gi inside out, then soak overnight in a bath of vinegar
and cold water. About half a cup of vinegar to every gallon of water is sufficient; the
acidity of the resulting solution will set the dye, and help reduce fading. After soaking,
rinse out the gi a couple of times in your washing machine or by hand - add some washing
powder (and fabric conditioner if desired) for a pleasant, vinegar-free smell. Sebsequent
washings may include additional vinegar or salt to further slow fading.
2: Wash pants separately, blue with blue and white with white.
3: Ensure all soap is rinsed out thoroughly, residue will
cause blue to bleed.
Can
I set the dye in my Blue judogi?
Vinegar is not the answer!
Many people who know nothing about this subject
recommend 'setting' dye in cotton clothing with vinegar. In fact,
vinegar can do nothing useful for cotton dyes. Vinegar will help set
some acid dyes, but only if applied while it is gradually heated to a
simmer (generally in the presence of salt), solely in cases in which
this necessary part of acid dyeing was omitted; acid dyes are used on
silk, wool, or nylon, but never cotton.
True Dye Fixatives
A
product called "Retayne", sold by local quilter's supply shops as
well as by most dye supply houses, such as Dharma Trading Company and
PRO Chemical & Dye,
is recommended by both Dharma and ProChemical for fixing dyes in
commercially purchased cotton fabrics or clothing to prevent color
bleeding during washing. This product is an ionic bulking agent, which
acts to seal in the dye by purely physical means, rather than the
chemical means which are so dependant on the type of dye. It seems
that the particles of Retayne adhere to the dye molecules, effectively
making them larger, so they do not come out of the fabric as easily.
Note that Retayne is washed in as a laundry additive, and thus can be
used only on things that can be immersed at least once without the dye
immediately floating off and ruining other parts of the same item.
Retayne may be removed by washing with overly hot water, and thus
treated items must be washed in cool water (which is always a the best
for your judogi).
Dharma Trading Company also sells a product
called "Dharma Dye Fixative", which they claim increases the
washfastness, wetfastness, resistance to persperation staining, and
resistance to seawater fading of several different kinds of dye. It
may be a generic version of Retayne, or a related product,
instead. Aljo Dyes strongly suggests the use of their equivalent
product, Aljo Pro-fix PCD after-treatment, after using direct dyes,
which would otherwise run too much to be at all desirable.
We would be very pleased to
hear from any of you who try these.
Perhaps we could give more
detailed recommendations with some
actual user feedback.
