7. Textile as Scaffold#
Technical textiles have various applications, among which agrotech, building, clothes, geotech, sports. In this class we will use textiles for composites, polymerisation, solidification, fabric formwork, crystallization, composites and biocomposites, agglomerates.
This class focuses on exploring techniques and applications of technical textiles in the industry.

Assignment#
Each student can 2 out of 5 different techniques to make a prototype of a textile composite.
I focused on crystallizahtin and molding.
leather Molding#
Blending traditional moulding techniques with digital fabrication
Tools I need:
- chefoun instead of leather
- Wooden Block for 3D mold 7 mm thickness
- Clamps
- I used Glycerine instead of Vaseline
- gypsum instead of textile hardner
- CNC machine
Steps on CNC milling#
1) Create 3D modeling with Rhino i don’t have a vacuum, so I designed my mold as a positive - negative
2) Using the Shopbot to cut the 3d model, so the first thing was to take the stl file and uploading it to VCarve in order to get the profile toolpath and the pocket toolpath to start milling. I upload the .stl file from file menu then press on import - import stl I edit the job size to (X= 200, Y= 350 Z= 40 mm) the dimension of the wood block, I chose 7 mm thickness, and complete all the sittings that need to start cutting. After send the file to SHOPBOT3. 3) Fixing the block on the CNC milling machine 4) Start cutting
Steps for Molding fabric#
After 4h on cnc machine, its time for leather molding
1) Before molding ,there is steps for fabric Processing,
- first, soak the leather in cool water (10 minutes),
- next heat a second pot of water,
- finally dunk the leather in the hot water.
but I did not used these steps because I chose ( chefoun ), so I think it depends on what fabric you choose.
2) I paint the mold with Glycerine to prevent chefoun adhesion
3) painting the fabric with gypsum instead of textile hardner (to make it harder)
4) finally molding, I put the chefoun in the mold and press it and leave it for the next day.

Crystallization#
Refer to the solid-liquid separation and purification technique in which mass transfer occurs from the liquid solution to a pure solid crystalline phase.
Copper Sulphate Crystals#
Copper sulfate crystals are among the easiest and most beautiful crystals you can grow. The brilliant blue crystals can be grown relatively quickly and can become relatively large.
Recipe:
- Copper Sulphate
- Water
- Jar or beaker
Steps for crystallizing:
1) Stir copper sulfate into very hot water until no more will dissolve.(You can just pour the solution into a jar and wait a few days for crystals to grow, but if you grow a seed crystal, you can get much larger and better-shaped crystals.
2) Put a thread inside the solution for few hours, I put the thread for 2h and got a nice result.
*note:
1) uspend the seed crystal in a clean jar that you have filled with the solution you made earlier. Don’t allow any undissolved copper sulfate to spill into the jar. Don’t let the seed crystal touch the sides or bottom of the jar. - I thuaght if keeping the seeds in side the jar will give me a quaick, but it gives me a mass of crystal and also the jar covered with crystal.
2) I was trying to add color in the solution to see if it gives me a new color. - I chose Indigo (blue) and food coloring (red) color addition. - I have got a new color. the solution with indego gives me a darker blue. And the solution with red gives me a green crystal.
3) Place the jar in a location where it won’t be disturbed.
