in step (9) is made by compressing said combination by said
pressing head with 1600 tons of force for 40 minutes in a mold at
160 degrees of Celsius.
Description
FIELD OF THE INVENTION
[0001] This is a Continuation-In-Part application of applicant's
former patent application with application Ser. No. 09/630,218,
entitled "shoe sole made of bamboo and method for manufacturing the
sole", filed on Aug. 1, 2000.
BACKGROUND OF THE INVENTION
[0002] Conventional shoes are made of plastic material or leather
and generally includes a heel portion, an outsole, an insole and a
vamp. These parts are connected with each other by way of stitching
and/or gluing. Stitching is used to combine leather sheets and
requires a lot of time to finish a pair of shoes so that the
stitching is not suitable for those shoes which have low price and
not composed by plastic sheets. Furthermore, some plastic material
cannot be stitched and some plastic sheets tear off at the
positions where stitching passes. Therefore, the plastic sheets are
usually combined by gluing. Many scrubbing steps are taken on the
plastic sheets before the sheets are glued and this type of shoes
are not suitable to be recycled.
SUMMARY OF THE INVENTION
[0003] In accordance with one aspect of the present invention,
there is provided a method for manufacturing shoes and comprising
the steps of step (1): to remove oily and organic substance from
bamboo; step (2): to split the bamboo into plates; step (3): to
sanitize the bamboo plates; step (4): to dehydrate the bamboo
plates; step (5): to cool the bamboo plates; step (6): to cut the
bamboo plates into sections; step (7): to soften fibers in the
bamboo sections in step (6); step (8): to glue the bamboo sections
in step (7); step (9): to compress the bamboo sections in step (8)
by a pressing head to form a combination; step (10): to heat the
combination in step (9); step (11): to cool the combination in the
step (10), and step (12): to machine the combination in step (11)
to be desired shapes.
[0004] The primary object of the present invention is to provide a
method for manufacturing shoes made of bamboo sections so as to
reduce consumption of woods.
[0005] These and further objects, features and advantages of the
present invention will become more obvious from the following
description when taken in connection with the accompanying drawings
which show, for purposes of illustration only, several embodiments
in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is a flow chart of the method in accordance with the
present invention;
[0007] FIG. 2 is an illustrative view to show a cross section of
the shoes made by the method of the present invention;
[0008] FIG. 3 is an illustrative view to show a combination of
bamboo sections in the method of the present invention, and
[0009] FIG. 4 shows a shoe made by the method of the present
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] Referring to FIG. 1, the method of the present invention
comprises the following steps:
[0011] step (1): To remove oily and organic substance from bamboo
by using a liquid mixed with aqua-ammonia and ammonium-hydroxide.
The liquid is heated up to 120 to 160 degrees Celsius for 24 hours
to remove oily and organic substance from the bamboo in step (1).
The remains in the bamboo can be removed by using steam to
evaporating the remains.
[0012] step (2): To split the bamboo into plates.
[0013] step (3): To sanitize the bamboo plates by using a liquid
mixed with hydrogen peroxide and formadohyde. The liquid is heated
up to 120 to 160 degrees Celsius for 24 hours to sanitize the
bamboo plates.
[0014] step (4): To dehydrate the bamboo plates by heating the
bamboo plates from 40 degrees Celsius to 100 degrees Celsius for
168 hours until the liquid in the bamboo plates is reduced to 6% to
8%.
[0015] step (5): To cool the bamboo plates for 72 hours from 100
degrees Celsius to 13 degrees Celsius.
[0016] step (6): To cut the bamboo plates into sections 1 as shown
in FIG. 3 and arrange these bamboo sections 1 to be overlapped with
each other according to the sizes of fibers 10 of the sections as
shown in FIG. 2.
[0017] step (7): To soften fibers in the bamboo sections in step
(6) by soaking the sections into a liquid comprising
caustic-soda-flake.
[0018] step (8): To glue the bamboo sections by water-base glue
such as poly-ethylene-vinyl, SBR-Latex and hardening agent.
[0019] step (9): To compress the bamboo sections in step (8) by
pressing a pressing head with 1600 tons of force for 40 minutes in
a mold at 160 degrees of Celsius to form a combination.
[0020] step (10): To heat the combination in step (9) in a oven
with 40 to 80 degrees Celsius for a month to prevent from have
fungus.
[0021] step (11): To cool the combination in the step (10) in a
shaded place for three months.
[0022] step (12): To machine the combination in step (11) to have
desired shapes.
[0023] By this way, referring to FIG. 4, the combination can be cut
or machined to be desired area and shapes. For example, the
combination can be made to be a heel portion 22, an insole 21, an
outsole 20 or an upper 23 of a sandal. When the combination is used
for a shoe, the whole sole portion can be made by the bamboo
combination. The bamboo grow quickly and are environmental friendly
so that the method can resolve the shortcomings of the shoes.
[0024] While we have shown and described various embodiments in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
