Knotplex

From timelab

Knotplex is a product of Knotfactory, next to Knotpot.

Testing Knotplex recipes[edit | edit source]

Knotplex, our first semi-finished product based on Japanese Knotweed. During this research, we do not focus on product applications, but on the different characteristics of the material when changing the recipe. We chose a plate, as this being a simple and representative shape to explore the recipe and compare characteristics.

During the research we explore settings such as temperature, pressure, matrix and binders.

20 g casein
50 g hide glue

SETTINGS
8 ft
20 minutes pressing time
80°C heat press, one side

STEPS
1° We shredded the hide glue and mixed it with the casein
2° We added the 66 g of short fibres of Japanese Knotweed
3° We mixed it with 120 ml water
4° We put it in the press (between baking paper) for 20 minutes, and 80°C, only the bottom side of the press was heated.


ANALYSIS

Pros Cons
- very strong
no prep time needed to heat the glue
- both casein and glue is maybe an overload
longer drying time (2 days)
sticked to the mold


LEARNING LESSON

take the plate of of the mold and let it dry into a drying mold, to avoid sticking to the mold.

3° Press for 15 min each side.


ANALYSIS

Pros Cons
strong, no glue needed very wet, a lot of water came out
'holes' because of the larger particles.


LEARNING LESSON
use less water? good idea to turn plate half time to heat each side.
More filler needed to fill the holes in between the larger particles.

These experiments where inspired on a recipe from Precious Plastic. The sheets are pressed during a hot proces.

experiment with orange with heat


INGREDIENTS
100 g orange peels
10 ml water

SETTINGS
5 ft
20 minutes pressing time
140°C

STEPS
1° Dry the orange peel and crunch them so it becomes like coffee grounds
2° Add the measured water to the orange grounds and mix it thoroughly.
3° Put it in the mold and press it like described in the settings.

ANALYSIS

Pros Cons
The surface is more smooth and equal The material fell apart
This knotplex was ready after 20 minutes pressing. That means it doesn't need to go in a drying mold for days Heat was added in the process


LEARNING LESSON
This test didn't turned out to what was expected. It didn't came out in one piece and felt more friable.



N° 2[edit | edit source]

This is a test with only water and Japanese Knotweed pressed under heat.

experiment with only japanese knotweed and water


INGREDIENTS
100 g Japanese knotweed
10 ml water

SETTINGS
5 ft
20 minutes pressing time
140°C

STEPS
1° Add the measured water to the Japanese knotweed and mix it thoroughly.
2° Put it in the mold and press it like described in the settings.
3° After 20 minutes, the test is 'baked' and doesn't need to dry afterwards.


ANALYSIS

Pros Cons
It only contains 2 ingredients It's not strong
It's friable


LEARNING LESSON
The heat from the hot process does something to the structure within. This test contains only water and Japanese knotweed, yet after serveral week it crumbled.

N° 3[edit | edit source]

In this test we wanted to add protein in a hot process. We already used this ingredient in a cold one and that turned out in a interesting test. Therefor we added some protein from protein shake in to the mixture.

Experiment with protein


INGREDIENTS
80 g Japanese knotweed
40 g protein
10 ml water

SETTINGS
5 ft
20 minutes pressing time
140°C

STEPS
1° Add the measured water to the mixture with Japanese knotweed & protein and mix it thoroughly.
2° Put it in the mold and press it like described in the settings.
3° After 20 minutes, the test is 'baked' and doesn't need to dry afterwards.

ANALYSIS

Pros Cons
Less water High temperature, more energy
It feels strong The edges crumbles a little


LEARNING LESSON
This experiment was quit interesting. The protein became hard in comparingson to the test with only Japanese Knotweed.

N° 4[edit | edit source]

We combined eggshells with a protein mix to explore the properties compared to the test with only one of the ingredients.

Experiment with protein and eggshells


INGREDIENTS
80 g Japanese knotweed
40 g protein
30 g eggshells
10 ml water

SETTINGS
5 ft
40 minutes pressing time
140°C

STEPS
1° Add the measured water to the mixture with Japanese knotweed, eggshells & protein and mix it thoroughly.
2° Put it in the mold and press it like described in the settings.
3° After 40 minutes, the test is 'baked' and doesn't need to dry afterwards.

ANALYSIS

Pros Cons
Hard material It crumbles in pieces


LEARNING LESSON
This test result compared to the test with only one ingredient shows us that maybe eggshells aren't a great addition to the recipe. The test with only eggshells and Japanese Knotweed crumbles also and is very brittle.

N° 5[edit | edit source]

In this experiment we searched for a filler that can be collected in a local setting. Eggshells for example is a large waste stream.

Experiment with eggshells


INGREDIENTS
80 g Japanese knotweed
30 g eggshells
10 ml water

SETTINGS
5 ft
20 minutes pressing time
140°C

STEPS
1° Add the measured water to the mixture with Japanese knotweed & eggshells and mix it thoroughly.
2° Put it in the mold and press it like described in the settings.
3° After 20 minutes, the test is 'baked' and doesn't need to dry afterwards.

ANALYSIS

Pros Cons
A cheap filler The eggshells won't easily attach to the Japanese Knotweed
Brittle


LEARNING LESSON
Same conclusion as test 4. Adding the eggshells makes the test more brittle ans fragile.

N° 6[edit | edit source]

This experiment contains a mixture with coffee grounds. Coffee grounds is also a bigger and local waste stream.

experiment with coffee grounds


INGREDIENTS
80 g Japanese knotweed
40 g used coffee grounds
10 ml water

SETTINGS
5 ft
20 minutes pressing time
140°C

STEPS
1° Dry some used coffee grounds so they won't mold
2° Add the measured water to the coffee grounds and mix it thoroughly.
3° Put it in the mold and press it like described in the settings.
4° After 20 minutes, the test is 'baked' and doesn't need to dry afterwards.

ANALYSIS

Pros Cons
Waste stream The mixture did not attach to each other and crumbles down
Fragile

STEPS
1° Measure the fibers and the casein. Mix them together.
2° Add water and stir until the mixure become foamy.
3° Put it in the mold and press it like described in the setting.
4° After 40 minutes, the test is 'baked' and doesn't need to dry afterwards.


ANALYSIS

Pros Cons
Solid plate
The orange color is a natural dye due to the hot process
It feels lighter than the other experiments (with hide glue)


LEARNING LESSON




N° 8[edit | edit source]

In this mixture we added starch because of its properties in the cuisine.

experiment with potato starch


INGREDIENTS
80 g Japanese knotweed
40 g Potato starch
10 ml water

SETTINGS

Japanese knotweed and Fish glue

In this result I want to test another type of glue. Just so we exclude question about other glues.
INGREDIENTS
192 g Japanese knotweed
100 ml water
112 g fish glue

SETTINGS
7 ft
30 minutes pressing time

STEPS
1° Measure the fish glue and add the water until it's a consitent mix.
2° Mix the glue with the fibers.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, put the sheet in a drying mold.

ANALYSIS

Pros Cons
It doesn't smell like Hide glue This glue did not attach to the Japanese knotweed fibers.
Cold process Fish glue is a very sticky composite


LEARNING LESSON
Using Fish glue in this application was a bad idea. The fibers didn't attach to each other, which results in just a pile of Japanese knotweed and some dried glue.

N° 2[edit | edit source]

Casein used as a binder

In search of another binder, I only used casein and water as a binder in this cold process.
The result was a good first step towards finding a binder in a cold process.
INGREDIENTS
80 g Japanese knotweed
120 ml water
40 g Casein

SETTINGS
7 ft
90 minutes pressing time

STEPS
1° Measure the fibers and the casein. Mix them together.
2° Add water and stir until the mixure become foamy.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, put the sheet in a drying mold.

ANALYSIS

Pros Cons
No hide granules needed The surface is not equal
It didn't smell like the hide granules During the drying period, it molded
Cold process


LEARNING LESSON
The casein could replace the hide granules. The process needs to be more explored to find a better recipe that fits our requirements.

24/03/2022[edit | edit source]

More water added


INGREDIENTS
185 g Japanese knotweed (155g fine + 30g rough fibers)
300 ml water
160 g hide glue

SETTINGS
8 ft
30 minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, put the sheet in a drying mold.

ANALYSIS

Pros Cons
The sheet is hard The glue became more flexible
More water added to the granules When under pressure the liquid glue diffused to the sides of the mold
Cold process


LEARNING LESSON
It looks like this result has a more equal surface. The glue is more divided and the fibres are more smooth.
Yet there was a lot of glue that under pressure came out of the mold. So maybe we need to use less glue.

Selina's first knotplex result


INGREDIENTS
185 g Japanese knotweed (155g fine + 30g rough fibers)
200 ml water
160 g hide glue

SETTINGS
7 ft
45 minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, put the sheet in a drying mold.

ANALYSIS

Pros Cons
The material is hard The surface is rough, unequal
Cold process


LEARNING LESSON
I wonder if the proportion glue/ fibers has something to do with the unequal surface. Maybe if I used less glue, the fibers can have more space to settle.
