INTRODUCTION

What if the daily garments could clean the air from the Co2?

The fashion industry is notorious for being the second most polluting on Earth, next to oil and gas. Fast fashion brands have made clothes cheaper, trendier, and more accessible than ever, but this comes at the high cost of diminished resources, dangerous production conditions, chemical exposure, energy spent on transportation, and GHG emissions when these items are thrown in a landfill.
The 50 % of fast fashion items are discarded within a year of purchasing. Less than 1 % of textiles are recycled, and 1 garbage truck full of textiles is landfilled or burnt every second.
Driven by technology, this multidisciplinary research focuses on the application of environmental “cleaning” material able to reduce the Co2 in the air placed on a garment. Pursuing these goals would be enabled for the fashion industry to boast better economic, environmental, and social outcomes — opportunities lost by the current linear textiles system.

TECHNOLOGY

Today, many technologies are exploring new strategies for environmental “cleaning”. One of these merging technologies is from PrimLab company with “CO2pure”, a mineral compound that converts Carbon dioxide and Nitrogen oxide into environmentally safe minerals.
CO2pure,  excellent product in microparticles, is a 100% natural mineral compound with the property of mineralising the main greenhouse gases (CO2 and NOx), reducing these gases on the area where they are applied. As the product reduces CO2 and NOx, simultaneously is also reducing the VOC (volatile organic compounds). Also, the product acts as a photocatalytic and catalytic modulator to interact with NOx at the chemical level. Furthermore, its catalytic modulators allow the material to be active in both day and night. Assuming that the CO2pure is handy material able to be applied on a soft, flexible and widely surface such as textiles, yarns and 3d printer filament, this research investigates the application of the Co2Pure in the additive manufacture process for the garment design production.

HYPOTHESIS

Based on the above knowledge, the Wearpure project starts the material investigation with a question: How can we maximize the capacity of Co2Pure once is applied on a garment?

To answer, we take into consideration the two main actors that influenced the behaviours of the Co2Pure material on garments: the wind, as environment forces necessary to catalyze the Co2, and the human body as a transmitter of needs. A 3d walls will be generated as tunnels over the body, to canalized the wind, consequently, a human body will be observed to understand the application of the Co2Pure in the strategic areas of the tunnels, in order to maximize the efficiency of the material and not disrupt the movement of the garment.

METHODOLOGY

The design strategy is defined by three sequential steps: a) Digital simulation b) Material fabricability and d) Design application. The aforementioned design strategies allow for accuracy as well as high-performance optimization and predictability in such complex design tasks, enabling the creation of customized products, designed for individuals.

DIGITAL SIMULATING

Virtual testing can take place as part of a digital experience that links the diverse steps in a production cycle—from the resource extraction stage to production and then. The digital model allows exploring the impact that proposed projects will have, optimizing logistics, infrastructure, environmental and disaster management and security—and beyond. Virtual cloth modelling and simulation provides a means to demonstrate and assess its performance before the cloth is made. The design has been the outcome of a digital juxtaposition of various data, such as body curvature maps, airflow and textile behaviours. Data body curvature of women athletes has been taken into consideration for the purpose of this research.

Analysis
Projecting the body curvature in the smallest area, for a case study development,  we investigate the forces and variables that will affect the tunnels shape over the human body.The research begins with a series of lines shaped by forces arising from body curvature and the variation, in term of density, length, and forces power.

In order to understand and prove the capacity of the tunnels to trap the air, we analyze the wind force in case study geometries. Using the CFD analysis (Computational fluid dynamics ) with one wind direction, the airflow gets velocity according to the tunnel geometry. By the colours, It is possible to see where the wind is taking velocity, mainly on the edge of the objects and on the narrow spaces,  and where it stopped.

Forme founding
Through the analysis, we collect enough information to generate a tunnel geometry able to perform for both material argumentation and garment comfort. In order to find the shape we have used an Evolutionary solver, a tool called Galapagos which facilitates this process within grasshopper(graphical algorithm editor).

Simulation
The Wearpure patterns have been designed with the simulation software support, Kangaroo, which allow us to preview the connection behaviours between the patches.

MATERIAL FABRICABILITY

Additive manufacturing
Addressing the overcome environmental pollution issue, Wearpure project developed a new PLA 3D filament material composed of Co2Pure powder with a biodegradable polymer.
Along the investigation, we observed the suitability of the 3D Co2Pure Filament on the additive manufacturing process, testing different sets of a 3D printing machine, in order to achieve a clean and well controlled 3d printed process. For the test, we needed taking into consideration that the filament contains a  Co2Pure powder (thickness, 30 µm diameter ) and its height resistance at the temperature. Therefore the test has been run using a nozzle 0.7 mm.

3D print on textile
In this stage, we analyzed how the 3d printing process behaves above the textile.  We selected eight different textile compositions, which goes from pure cotton to pure polyester with different characteristics as thickness and texture. The main purpose of the test is to define a good attachment between the 3D element and the textile as well as the flexibility and bending reachable by the geometry printed on specific textile
