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 an environmental “cleaning” material able to reduce the Co2 in the air placed on a garment. Achieving this, the fashion industry will be able to boast better economic, environmental, and social outcomes — opportunities lost by the current linear textiles system.


Today, many technologies explore 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 is a 100% natural, mineral microparticles, a compound with the property of mineralising the main greenhouse gases (CO2 and NOx), reducing these gases on the area where they are applied. While the product is reducing CO2 and NOx, simultaneously it is also reducing the VOC (volatile organic compounds). In addition, 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 during both day and night. Assuming that the CO2pure is a  handy material applicable on a soft, flexible and widely surface such as textiles, yarns and 3d printer filament, this research investigates the implementation of the Co2Pure in additive manufacture processes for the garment production.


Wearpure is a textile solution able to eliminating the Co2 and to reducing the GHG gases around us.
Wearpure’s challenge is to introduce new material solutions in the world of textiles and fashion, generating an ecosystem of climatic agents cable of reducing GHG gases simply by being in contact with the new material. Wearpure, made by 3d printing methods,  transforms the Co2 into no harmful minerals. By simply using the WearPure material on textile is possible to reduce the contaminated air in our daily space.







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

To answer, we take into consideration the two main actors that influence the behaviour 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 canalize the wind, consequently, a human body will be observed to understand the application of the Co2Pure in the strategic areas of the tunnels. The aims are to maximize the efficiency of the material and to not disrupt the movement of the garment.

 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.


Virtual testing takes place as part of a digital experience that links the diverse steps in a production cycle—from the resource extraction stage to production. The digital model allows exploring the impact that proposed projects will have, optimizing logistics, infrastructure, environmental and disaster management, security—and beyond. Virtual cloth modelling and simulation provides a mean 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.


To approach the digital analysis, we reduce the working area, taking as a case study a 10x10cm patch area.  We investigate the forces and variables that affect the tunnels shape over the human body. The research begins with a series of lines shaped by forces arising from body curvatures and the variation, in terms of density, length, and forces power.


In order to understand and prove the capacity of the tunnels to trap the air, we analyzed 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 range o colours from white to black, It is possible to see where the wind is accelerating (mainly on the edge of the objects and on the narrow spaces)  and where it stopped.


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


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



Additive manufacturing

Addressing the environmental pollution issue, Wearpure project developed a new PLA filament material composed of Co2Pure powder and a biodegradable polymer. Along the investigation, we observed the suitability of the 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 took into consideration that the filament contains a  Co2Pure powder (thickness, 30 µm diameter ) and the fact that it is highly resistant at the hight temperature. Therefore the test run using a nozzle 0.7 mm.


3D print on textile
At this stage, we explore how we can 3D print on top of a textile.  We selected eight different textile compositions, which vary from pure cotton to pure polyester with different characteristics as thickness and texture. The main purpose of the test was to identify a good adhesion between the 3D element and the textile as well as the flexibility and bending of the geometry printed on specific textile.
