INTRODUCTION

The design language is often interoperable in various fields, and the use of the same elements in different fields will produce new functions and aesthetics. We defined it as properties transferring. And this project is about the properties of a material transferring to another one contrastive material.

We mainly focus on the design language of fabric transformation in fashion design, taking these common techniques in fashion design as our design vocabulary, and organizing them into our design language. Decorative textures and functional seams that are used on flat fabrics in fashion design

become the primary structure in our designs, forming three-dimensional objects of different sizes, such as different sizes of chair, on a whole piece of two-dimensional fabric.

While exploring the morphology, we are also studying the process technology that can transfer the morphology of one material to other materials.Here we have chosen the lost wax casting that allows us to transform soft fabric into lightweight and hard metal. The aesthetics of fabrics that are not related to traditional architecture can be presented as a metal architectural language with strong material contrast.

CHAPTER 1:

INITIAL STUDIES OF MATERIALS

INTRODUCTION OF LOST WAX CASTING

INITIAL STUDIES OF MATERIALS

- Material Research

- Material testing

- Metal Casting testing

The first key point of this project is to understand the special properties of the material we need. In order to realize our theme, we selected various soft fabrics in fashion design as the research objects, took strong metal as the target, and explored the possibility of fabric shape that cannot be achieved by other materials. In the experiments, we used wax to assist the fixing of the fabric form.

1 Creating an object 3 Fireproof clay is put into the impression, making a sharply defined duplicate of the original model.

5 Hot wax is poured into the gap which produces a clay model covered in wax

7 A finely granulated flour is applied to the surface of the model for making an “investment mold"

8 Pouring in the liquid bronze at the top

2 The model is put into a bed of elastic and shapable material held in place by a rigid outer mold. When the model is removed, its impression remains.

4 When this second model is returned to the mold, there is a gap between the model and the mold for pouring wax.

6 Wax pipes are attached to the wax-covered model for flowing molten wax, molten metal and air when pouring metal in.

Variable:Number of times that dipping in wax

Cotton rug canvas dipping in the wax liquid for different times in order to observe the morphological changes of the wax attached to the mesh fabric. The wax liquid formed a drop-like solid wax column more evenly along the grid. Since the cotton rug canvas hardly absorb the wax liquid, the adhesion of the wax is directly related to the temperature of the wax liquid.

Variable: 3 dimensional shape of the fabric

Cotton rug canvas in 3 dimensional shape dipping in the wax liquid for different times in order to observe the form changes Comparing with 2 dimensional fabric mesh, the wax liquid formed the drop-like solid wax column in different directions. In addition, the fabric cube with wax also was burnt with fire to create holes on the surface which increased morphological possibility.

Variable:Mixing of different substances with wax liquid

Different substances are mixed with wax liquid such as pigments and glues. Some are paints and glues mixed with wax liquid acting on the fabric mesh. Some are the paint and glue first attached to the fabric mesh and then dipped in wax.

INITIAL STUDIES | MATERIAL TESTING

Creating texture: Burning

We used two-dimensional mesh fabric to make a three-dimensional box and then dipped it in wax, then used it as a candle and burned it in a few unevenly distributed places. The burnt area presented unique texture.

INITIAL STUDIES | MATERIAL TESTING

Creating texture: shaping wax in water

There are two ways to shape wax with water which are stirring while pouring, and stretching by lifting solidified wax in water. Water created a natural, organic texture on the wax.

Creating texture: Shaping wax and fabric in water

We combined all the previous experiments and did a new experiment of shaping both wax and fabric in water. Waxes not only held deformable fabrics in shape but also created texture on their surface.

INITIAL STUDIES | MATERIAL TESTING

Creating form: Exploring the potential of fabric by using fashion design techniques

According to our research on properties of different fabric, we decided to use spongiprene to continue the further development which is exploring the language of form through sewing and stitching. Then the fabric can be solidified with the shape by dipping in wax.

Preliminary material experiments helped us select the best fabric for further development. The next step to do is to conduct research experiments on this specific fabric. It started with some research common techniques in fashion design and taking them as our design vocabulary, and then organizing them into some more complex forms as our design language.

This part is looking at the feasibility of casting precision, which inspired us that in the step of waxing and fixing the fabric. Here we introduced a frame as a measurement to control the precision of the shape.

INITIAL STUDIES | IDEA APPLICATION

We used the frames for fixing 5 pieces of fabric with stitches and the edges of part of the fabric according to the ruler on the frame so that each fabric can be connected together one by one. Not only the function of controlling the connecting part, but also made fabric stretch to a great extent. After that we brushed wax on the fabric so that the fabric solidified and fixed in these shape and can be removed out of the frame. Because of the wax dipping process, these unique shapes can be preserved and transferred to different materials.

Based on a detailed study of the stitches, we further extracted the language use the fabric.

Taking into account the casting process and necessity, the area of thecloth was reduced and the three-dimensionality of the stitches increased, usingcurves to guide the framing and development of the entire project.

In our experimentation, we found that dividing a fabric surface into strips of equal widtharrangement and interpreting the stitches on the strips reduced the area of the fabric, while such stitches had the potential to create a richer form.

The three-dimensional samples thus generated from a flat surface are subject to a number of design constraints.

Firstly, the form of the sample is related to the drawing on a flat fabric.

Secondly, the stitches of the thread shapes are linked to each other in different places, which can also produce variations.

Finally, the process of hanging the sample on a square frame in ccordance with the shape of the sample allows further control over the form of the sample.

APPLICATION | 1:1 SCALE OF CHAIR

A full-size chair is assembled from several parts. Every piece is cut and sewd symmetrically and also assembled to form a symmetrical chair.

With a proven workflow, we tried to make a chair on a 1:1 scale. We made the chairin several parts separately. They were then assembled and fixed to the frame, eachpart being connected to the other using interlocking, juxtaposing and nestingmethods.

APPLICATION 1:1 SCALE OF CHAIR

We have a rich approach to the details of our projects. This is not only in the size ofthe stitches, but also in the combination of stitch curves and fabrics, the interlacingbetween stitches, etc.

The design has been in a symmetrical design context for a long time and we havetried to break it from certain angles.

By cutting the threads of some of the fixed parts.each time a control thread is reduced, a part of the chair changes under the influence of gravity. The symmetrical sewing with the free flowing state of the objectbetter expresses the fluidity of the material and at the same time breaks thedistanced and serious atmosphere of the project.

APPLICATION | ASYMMETRIZATION

After cutting the controlling threads, we repeatedly reversed the entire frame tocreate a rich variation in the form of such a soft chair. We weakened the control overthe fixation of the chair, using gravity to create variations in form and observation.The symmetrical handwork produces a rich variety.

APPLICATION | DEFORMATION

The focus of the work shifts from trying to achieve a symmetrical figure to allowingthe chair to produce a more free-flowing form. This state of affairs is not only moreplayful, but also an expression of our reflection on materials, craftsmanship and howto introduce free change

At this stage we wanted to incorporate wax into part of the design so that the stool would maintain its shape with the wax before moving on to the metal casting step. In addition, we also hoped that the fabric stool can be separated from the wooden frame support to achieve self-support after being hardened by wax.

Stool Development | Design for metal casting

After testing the ideas previously, in this optimization stage we aimed to design the stool which is potential to move on to the metal casting step. So we designed the basic shape of the stool with a quadrilateral seat and 3 chair legs, and scientifically considered the structure of the distribution of the fabric to achieve self-support.

Structural Optimization | Selected Structure

Following the structual optimization, a material layout calculation resulted in reducing parts of the volume, while still enabling the necessary stiffness, comfort and functional requirements to be met. On this basis, a variety of forms were generated for selection, and we selected an ideal form as a reference for subsequent development.

In practice, the position of the fabric followed the direction of the optimized structure in the digital model as much as possible. Although it is impossible to completely follow every structure, it also covered all parts of the optimized structure with fabric to ensure that the stool could stand stably.

Stool 1 | Limitation

In this stool, several overlapping layers of fabric resulted in a heavy visual effect. Each single piece of the fabrix is also too wide, so the excessive use of materials led to the ineffectiveness of the optimized structure.

Stool 2 | Distribution of the fabric following the selected structure

This stool is a relatively successful result. On the basis of following the optimized structure, it reduced 30% of the fabric compared with the previous chair. Therefore, this stool will be sent to be cast into metal.

Stool 2 | Optimization of waxing technique

For the problem of texture loss caused by the previous operation of brushing wax on the fabric, a technical improvement has been made at this stage.

It is difficult to maintain the high temperature of the wax liquid by first melting the wax into a wax liquid and then brushing it on the fabric, so the wax liquid can only soak into the shallow layer of the fabric which would cause the loss of texture.

The solution to this problem is to paste warm wax on the surface of the fabric first, then use a heat gun to melt the wax and make it soak into the deep layer of the fabric in a high-temperature liquid state.

STOOL DESIGN | DEVELOPMENT

Stool 2 | Optimization of waxing technique

Stool 2 | Comparison of Fabric Sections

From the comparison of the cut surfaces of the fabric, it can be seen that the optimized waxing method enables the wax liquid to harden the inside of the fabric, so that the originally soft fabric becomes strong enough to be the self supporting structure.

Step 1: Pasting warm wax on the surface of the fabric Step 2: Melting the wax with high temperature and low speed wind Step 3: Blowing the wax liquid into the deep layer of the fabric with low temperature and high speed wind Limitation: Improper control of the use time of the hightemperature and low-speed wind would cause the fabric to be overheated and then damaged.

The 1st step of coating is to apply a layer of liquid that can make the coating gypsum slurry better adhere to the object. The 2nd step is covering the stool with gypsum slurry. The final step is to coat the outermost layer with a specific flour.

Step 3 - Metal Casting

After the fabric was burned off along with the wax, the plaster shell that remained was ready for metal casting. After burying the stool with sand that controls the temperature of the shell and fixes the position of the object, metal liquid can be poured from the opening. So the metal casting step is done.
