Introduction of our Technologies
The features of a materials
Polyester
A man made material which replaces shell, bu ff al o and nut materials.
Unsaturated polyester resin made from petroleum is used. Because of its thermosetting feature, it has been
extensively used to make buttons in apparel. In 1955, a technique using polyester resin to represent the glossy
e ff ect of shell was invented i n the U.S.A. This development repla ced acrylic buttons, which ha d been mainly
used up to then. As a substitute for shell buttons, polyester buttons spread all over Japan and they occupy a
great share in the global button product ion now.
Without limits t o designs, tremendous patterns can be made to show natural appeara nces, such as bu ff alo horn,
shell and nut materials, and depending on the di ff erent designs, there is a di ff erent making process for each.
One of the typical methods i s using an aluminum rod into which is poured polyester solution and heat is
applied to harden the material,t his is called "rod" material.
Another way is pouring polyester solution into a large rotating metal cylinder and with centrifugal force, it
forms a sheet of polyester, this is called "sheet" material. Combinations with other materials such as metal,
acryl ic, shell makes polyester buttons more appealing in the market.

The features of a materials
ABS
A materi al containing three kinds of plastics.
ABS is a resin compounded of the three plastics ‒ Ac rylonitrile, Butadiene & Styrene - and have the respective
properties; Acrylonitrile - heat resistible, hardness, petroleum resistance, weather resi stance. Butadiene ‒ elasticity.
Styrene - glossy e ff ect, excellent electrical properties, impact resistance.
It is known as the best material of the resin materials to plate buttons and the injection method is used. In Japan,
after 1970, as a substitute for metal buttons, ABS buttons came into common use and are frequently combined
with other materials.

Metal
Permanent elegant glow
Brass and zinc as the main raw materials. Metal buttons come in a tremendous variet y of colors. Brass
buttons are often seen on uniforms or blazers. Because brass has a soft property, embossing or cutting
processes are frequently used for production. Most brass buttons are formed by putting the top and bottom
parts together with a press / die set and the inside of the button is hollow. More meticulous designs can be
presented by die casting buttons. Zinc alloy is melted by extremely high temperatures and is poured into a
metal mold t o produce buttons. For the delicate designs, the rubber casting method is used. Metal buttons are
widely seen as uniform or branded buttons worldwide.

The features of a materials
Nylon
A man made materi al full of appearance giving natural accent.
Nylon resin came into use as a new material for buttons around 1960. Nylon is a genetic designation of Polyamide.
Nylon products are usually processed by injection molding. For example,to meet th e increasing demands for
combination products,metal part s can be combined without adhesive during the processes of injection. Nylon products
are rich in appearance and various patterns can be designed, such as close texture, leathers, barks and meticulous
motifs. Transparent or pearly e ff ects can be made as well . Nylon products have a high production rate, are light and
have great color fastness for dyeing.

The features of materials
Urea
Rooted in Ita lian craftsmanship
Urea buttons have exc ellent color fastness and are excellent substitutes for horn and nut materials. Urea is a
unique plastic material, which was developed to convey the natural appearances of wood, horn and nut
materials . We at IRIS have incorporated the techniques and machin ery from Italy into our production system.
Since it is not dyeable, all colors are mould - dyed. Each color of sheet is formed and each sheet is set to make
natural look appear. The ready material is pu shed into the machine to form into a round bar, then it is cut into
tablets. Each tablet is set in the metal mould and compressed with heat - treatment to make into buttons.
Compared with other materials,urea buttons have excellent properties of resistance t o weather, impact,
chemicals and heat. Due to its minimu m quantities, urea buttons meet the need of mass production market.

The features of a material
Shell
Beauty from the Southern oceans
Raw shell materials for buttons are mainly obtained in the Southern Pacific Oceans.
White mother - of - pearl shells, black - mother - of - pearl shells, Takase shells and Mexican Abalone shells are
commonly used, but almost all of them are imported. Being natural , the quality of material is graded by its habitat.
Taka se shell is the most frequently used and it comes in variety forms of buttons from thin 2 or 4 - hole style to shank
style. Takase shell is a spiral shell in conic shape, while other shells are bivalves (two - halve shells like mussels).
Because of its excelle nt pearly e ff ects and superb luster, white mother - of - pearl shell is ranked at the top and it fits
very well with the elegant and luxurious wears. For a long time, shell buttons had been a hand - made pro duction
before machinery was invented in the 19th. century. Most of the production processes are cutting processes to treat
the outer shells, and long - experienced skilled techniques are especially required for the finishing processes.

Nuts
So cal led “Ivoly Nuts”
Ecuadorian coconut (Corozo Nut) is the raw material. It is known as "Ivory nuts" or "Vesitable nuts", as the
outer of the seed looks like ivory once the she ll of the nut is removed. The fine grain and gloss are distinctive.
Buttons are made by slicing the nut into an appropriate thickness, taking out the blanks and forming each blank
into a button by cutting. The final process is polishing to make the button shiny. This production process was
originally developed and put int o automation in Germany and spread into northern Italy. Nut buttons are
commonly used with menswear.

Bu ff alo horn
Deep relation with human being.
After nuts and shells had been originally used as accessories ones, horns and hooves came into use. In the
ancient Greek era, these were valuable jewellery equivalent to gold and silver. Slicing so lid horns or splitting
hollow horns in half, blanks are taken out to make buttons. The tip of horns is frequently used as toggle buttons.
In the 19th. century, decorative horn buttons were developed by applying pressure to make a relief on it. With
this me thod, the portrait of Josephine and Marie - Louise (the first and the second wife of Napoleon) was
embossed on the button.

The features of materials
Woods
Adored beauty from the ancient days
From ancient times to present, wood buttons have been long made. Woods buttons were made by being carved out
of a single board of boxwoods, magnolias, cherries, ebonies or olives. But nowadays, plywood is the main material.
The main trees of plywood are birches, beeches and lauans. Phenol resin is impregnated and after it is naturally
dried outside for a half day, it is dried for another three hours inside with the heat at 60 to 70 centigrade. To make
the buttons, cutting processes are conducted. To make the best use of fine grains, a burning e ff ect can be applied or
wood buttons can be combined with other materials. Even the color inconsistency of wood buttons conveys the
sense of natural beauty.

The features of a materials
Leather
Sense of wild nature
Skins of cows, horses and goats are the raw material of leather buttons. The hides are mainly imported from
America and Australia. They are tanned by treatment with tannic acid or chrome. The hide with the tannin
treatment is used for buttons. Leather is cut and shaved o ff to appropriate kinds of forms for button production.
Putting leather strings together by artisans or embossing a design on a plain leather sheet, leather is made i nto
buttons. Artificial animal skins can be represented by embossing a single sheet of plai n leather. Taking di ff erent
textures between top and back of the leather into design or showing di ff erent tones like distressed appearance with
additional processes, d istinctive features of leather gives buttons a unique accent. It is said that a wide variet y of
leather buttons were made in the 19th.century. In the present day, leather buttons are regularly used on coats.

The features of a material
Casein
Moderate sense of milky accent
In t he late 1920, production of casein buttons spread the world after the development of machinery in Germany
made its production automatic. In Japan it was called "Lact " and put into the market from around 1930. The
raw material of casein buttons is rennet ca sein, which is made from milk. Casein is a genuine dairy product. To
give buttons luster or patterns, white pigment, pearl essence or water are added to the rennet c asein and
compounded with heat and pressure treatment. Being formed into a bar or a sheet, drying them for a long time
before making buttons. Through its processes,it requires time and care with skilled artisans. High compression
resistance and chemical re sistance, excellent colorfastness for dyeing are the great properties of casein buttons.

Environment Activities
IRIS Co.,Ltd. have taken a part of
“Ecolog recycling network” since 1994.
The "ECOL OG" items are only made of 100% polyester materials that are superior in waterproofing, ventilation, moisture
retaining & high resistance. "Ecolog" clothes only use outer - fabrics, li nings, interlinings, buttons, zippers and pads, which
are made of 100% pol yester materials. A fter using "Ecolog"products long time, they are collected and recycled to become
materials for buttons, zippers, pads & interlining, etc. again.
"Ecolog recycling network" is the best circular system to recycle used clothes.
But tons become abrasiv es.
When producing buttons, wasted parts of materials are left and they can not be used for button production.
IRIS regard the left - oveer materials as preci ous resources. The main materials are unsaturated polyester of thermosetti ng resin and urea
a mong a various materials for button production,and their ratio of leftover material is very low.
Grinding the leftover materials, they become a powder form of abra sive, which works well to remove paintings o ff airplanes and to
deburr thro ugh semi - conductor production. IRIS have operated abrasive production since 1898.
