Transcript of Self Cleaning & Repairing Textiles

Clean Break Fabrics By Julia Lamb,Rose Holleran,Becky Miller,Beth Heaton,Kelly Preston and Catherine Burgess Introduction A range of SMART upholstery fabrics designed for sofas for the home or public use which have been treated with a non-visible self-cleaning and repairing nano-particle coating. Why This Product Past Cleaning Methods Self Cleaning Technology There are currently two self-cleaning processes being developed that both involve nanotechnology:-
Extremely water repellent, microscopically rough surfaces mean that dirt particles do not stick to the surface and therefore can be removed by a simple rinse in water.

This is known as 'Lotus Effect', where water 'rolls' off the leaf -

The second process is given by photo
-catalytic layers:
This consists of a layer of
nanocrystalline titanium oxide or silver
ions, which reacts with the dirt particles
and are destroyed or 'cleaned' by UV solar rays.

Current self cleaning fabrics not only resist coffee and red wine stains but are also repellant to water, dirt, odour and are antibacterial as well. Self Repairing Technology The way that it works is by having tiny capsules that are filled with the self healing agency which are embedded into the fabric.

When there is damage to the fabric this causes the capsules to break and the self healing agency leaks into the tear filling it in.

It will then polymerize
which means that the monomer
molecules bond forming a
polymer chain. Trends and Designs Although through our market research survey we found that not everyone was interested in trends for the home, we imagine our fabrics would be launched in 2014, coinsiding with the Epoch interiors trend. This trend is fitting as it's classic and timeless, inspired by vintage 1900s which was also the era of new technological discoveries; linking well with the sustainability of our product and the smart, innovative concept being a new 'discovery'. Women spend over 18 hours a week on cleaning and housework. Fabric Samples/Swatches The group decided our product would be best suited to upholstery fabrics, initially for sofas, as they are widely known to be one of the most awkward surfaces to clean easily.

We agreed that Self Cleaning and Repairing Technology would be most useful and beneficial to products such as sofas and curtains that often require professional cleaning which can be very costly, time consuming, and bad for the environment.

This Self Cleaning and Repairing nanotechnology is a
cheap non-toxic and eco friendly treatment that can be
applied easily onto fabric during manufacturing, which
can make cleaning of the upholstery far less necessary.

Your mind can be at rest as spilled drinks and food will no
longer need rigorous cleaning as liquids will not soak in and stain the
fabric due to the chemical coating. Research into biomimicry shows how new nano-particle finishes and coatings can be added to fabrics, which then greatly reduce the need for chemical cleaning. The Lotus leaf repels water, this can be mimicked by new technology which can then achieve the same effects.

Self Cleaning titanium dioxide based technology can offer an easier removal of stains, and repels dirt and water and has no loss of effectiveness over time. Dust & Asthma ?
Testing? The process to create anti-microbial fabric is done by coating the polymers and mono filaments of the fabric in silver ions and incorporate biocide agents into the fibers.

The silver ions can destroy the bacteria on contact or they can inhibit growth of more. Existing Products Market research survey Mintel Reports research Stain removers account for 70% of UK retail sales of fabric care products
82% buy fabric care products from 'grocery multiples' (Tesco, Asda...)
77% of people said that removing the toughest stains is the most important factor influencing their choice of stain remover
55% of people were worried about using stain removers on expensive fabrics
45% of people regularly bought upholstery cleaner out of a range of products
9% of people use upholstery cleaners once a week
12% of people have paid to have carpets and upholstery cleaned professionally Future Developments Industry feedback Materials Sustainability Households are saving money as products such as sofas that use the technology will last longer, and so will not need to be updated as often
Fabric care products will also be bought less frequently
The technology used is non-toxic and environmentally friendly; there is no waste from self cleaning methods
Less water and energy would be used, e.g. through professional cleaning
Less time would be spent on household cleaning
Some of the sofa fabrics have to be professionally cleaned therefore this is not cost efficient
Even though some sofa covers can be washed, they have to be washed at 40 degrees which is bad for the environment. 30 degrees is the recommended temperature popular sofa fabrics:
Hollowfill fibre
wool blend fibre
100% cotton
100% polyester chenille
plain linen
brushed polycotton
quallofil fibre '' Any product that helps keep sofas clean is a bonus as it can become a very expensive job if a stain cannot be removed. Also household dust after a length of time can work its way into the fibres of the fabric and make the fabric look grubby''.-Jill Blackburn, Websters Furniture 'Multi York' sofa company offer washable covers for their sofa's. This has to be washed at 40 degrees which is bad for the environment anyway. 'I do agree that nanotechnology has its uses in mass market textile construction, in fact i wrote an piece on the subject way back when i studied textile technology at college. Self cleaning products, or antibacterial/nano silver at least, if im right have now started filtering into technical fabrics such as nurse/doctor uniforms, hospital and hotels etc.'-Victorian Plumbing An online survey was carried out, to find out the market's opinions of our product. Through this survey we found:
100% of people surveyed thought the concept was a good idea
Our market would be families with children and pets
People clean their homes 'a few times a week', so the task of upholstery cleaning and refreshing removed could improve this
The main cause for dirt is spilt food and drinks - stains that can be broken down with our technology
Other future development suggestions were carpets, clothing and cars
Trends for the home (colours, fabrics...) were not as important to people as we thought We can imagine our concept to be used within a range of fabrics for products such as curtains, cushion covers and bedding

Market research told us that carpets were an area people found difficult to clean within the house, so carpet, rugs and flooring are also potential product areas

Children and baby products such as clothing, car seats, high chairs, bibs and mats are also products that could benefit from self cleaning and self repairing technologies

Pet bedding, toys and mats are another potential development Before modern detergents were invented soda crystals and bluing was used to wash fabrics. Soda crystals are white crystals, Used to wash fabrics that had stains, oils and grease on them, these crystals were rather harsh on clothes/fabrics and hard on the skin.

Devises such as dolly sticks (used to agitate the fabrics), a wash board to scrub the clothes of even more dirt and the mangle, used to wring the fabrics/clothes out were used.

This was a lengthy and tiersome process. Sport & Apparel wear The U.S. military spent more than $20 million developing fabric, protect soldiers from biological attack.
Jeff Owens, one of the scientists who developed the process, said "During Desert Storm, most casualties were from bacterial infections -
We treated underwear for soldiers who tested them for several weeks and found they remained hygienic. Self Cleaning Shark Bed Company of Animals unveils the future of pet bedding at Crufts.
Nano Pet Products LLC creates a cleaner and healthier environment for both you and your pet using nanotechnology The shark-skin suit worn by world-record breaking Olympic swimming champion Michael Phelps. The suit, which includes a plasma layer enhanced by nanotechnology to repel water molecules. Nanotech Coating Uses Sunlight to Banish Smelly Socks Forever

Today cleaning methods have become easier with the invention of the washing machine and dry cleaning in the1700's however this is still expensive and time consuming.
Dust mites are most commonly found in soft furnishings
like carpets and upholstery fabrics.

To combat dust mites regular vacuuming for a time of six
to seven minutes needs to be done, carpets and soft
furnishings need to be thoroughly cleaned every twelve
to eighteen months.

This is requires a huge amount of time and energy. Dust mites are the most common trigger of allergy and asthma symptoms. Dust and dirt particles collect and the easiest way to stop this happening is by having clean surfaces. Self cleaning surfaces will reduce the amount of dust mites settling on fabrics creating a healthier environment to live in. This tells us that people do care about upholstery care, yet want convenience (buying in supermarkets, paying for professional cleaning...)
