Fabric grown in vats of tea is being used to produce a new type of material for the fashion industry.

The material, which has a leather-like texture but is extremely lightweight, has already been used to make shirts, jackets, dresses and even shoes. It is the authentic “tea shirt” – an item from a range of clothing made from Britain’s favourite beverage. Fashion designers and scientists have developed a new fabric that is grown in vats of tea.

clip_image002_fabricScientists at Imperial College London have been working with fashion designers from Central Saint Martins College of Art and Design, also in the capital, to create the fabric, for use in the fashion industry.

They believe such innovative, sustainable textiles will become increasingly important for the clothing industry as pressure on the resources needed to create traditional fabrics such as cotton, wool and leather increases. The new fabric is grown in a soup of green tea, sugar and other nutrients, over the course of several days. Bacteria added to the solution produce long filaments of cellulose that clump together to form thin mats of fabric that float on the top of the mixture. Once dried, this becomes become see-through and similar in appearance to papyrus. However, it can be treated, dyed and moulded to produce different textures and effects.

Professor Paul Freemont, a molecular biologist at Imperial College London said: “The bacteria naturally produce these fibres of cellulose and they are laid down into a mat that floats to the surface.  “The mixture produces quite an uneven and random fabric though, so we are working on ways of making it more consistent. “Once it is dried, it feels just like leather and is really tough. You can’t tear it apart.” The green tea mixture helps encourage the bacteria, known as Acetobacter, to produce the cellulose filaments. Over a period of two or three weeks, these fibres meld together to form thin, wet sheets of cellulose that toughen as they are dried out. The project is being led by Suzanne Lee, a senior research fellow and designer at Central Saint Martins College of Art and Design, who has already used the material to make clothes.
