Latex Gloves
The first Latex gloves were manufactured
in 1964 by the Ansell Rubber Company founded in 1905 by Eric Ansell
in Melbourne Australia. Initially it manufactured balloons and
condoms, going on to manufacture the first disposable Latex gloves
in 1925. In 1945, Ansell designed and built the first automatic
dipping machine that produced 300 dozen pairs of Latex gloves in
eight hours. The manufacturing of disposable Latex gloves technique
used in this remarkable development was a major Australian
innovation.

Disposable Latex gloves manufacturing is
a long and complex operation that begins with the harvesting of
natural rubber latex (NLR) . Its main objective is to optimize the
properties (flexibility, barrier properties) of the latex material
while minimizing its adverse effects (allergies).
Latex is an emulsion of rubber particles
in suspension in an aqueous medium. The mean dry rubber content is
33%. The fresh latex harvested from the rubber latex tree (Hevea
brasiliensis) is unstable and must be processed rapidly after the
collection of the lartex in order to prevent spontaneous
coagulation. Latex gloves are manufactured from the concentrated
raw latex obtained by centrifuging and stabilization. Several
immersion stages are required to enhance the properties of the
rubber latex, in particular its mechanical strength and barrier
properties.
In order to make Latex gloves, in
addition to latex, one needs water, vulcanizing agents,
accelerators, activators, blockers, retarders, anti-oxidants,
preservatives, odorants, colorants, stabilizers, and processing
aids. In other words, you need a veritable chemical
soup.
Latex Gloves are created by dipping
forms (which look like hands) into vats of liquid Latex and admixed
chemicals. Latex Gloves forms are prepared by washing with a
detergent and rinsing. The latex gloves forms are then dipped in a
coagulant mixture to promote congealing of the latex around the
latex gloves forms. After being dipped in the coagulant mixture,
the latex gloves forms are dipped in the latex material. The coated
latex gloves forms are then dipped in a leach consisting of warm
water and then into a powder slurry consisting of powdered starch.
The coated latex gloves forms are then placed in an oven for 30
minutes. The latex gloves then harden on the molds - it is formed
with what will ultimately be the inside of the latex gloves
(touching your skin) on the outside of the latex gloves mold. Then
the latex gloves, still on the mold, go through one or more rinses
to leach out protein and residual chemicals (better rinsing equals
less residual). Finally, the latex gloves are stripped off the
mold, inspected, and then the latex gloves are
packaged.
