Fibres


Natural Fibres:
     
There are two types of natural fibres; Cellulose and Protein.
    
Cellulose fibres come from plant materials. These fibres are very absorbent, shrink when washed, crease readily but can withstand high temperatures. Resistant to alkali's, bleaches and organic solvents but damaged by acids. Cool to wear.

  • Cotton (Seed fibre)
  • Kapok (Seed fibre)
  • Linen (Bast/stem fibres)
  • Jute (Bast/Stem fibres)
  • Hemp (Bast/stem fibres)
  • Sisal (leaf fibres)
  • Ramie
  • Bamboo
  • NZ Flax

Protein fibres are divided into two classes; keratin (hair or fur) or secreted (insect) fibres. Wool is relatively weak with low wet strength, shrinks, high natural crimp, resilient and warm but absorbent. Silk is lustrous, stronger than wool, moderately resilient, absorbent, low abrasion resistance. 

  • Wool
  • Silk
  • Hair
These fibres will then be made into a yarn which will go on to be constructed into a material/fabric.

Construction:

Material/fabric fit into 3 different classes; woven, knit and non-woven.

Natural Dying:

Information Found: http://www.sweetlivingmagazine.co.nz/create-natural-dyes-with-plant-materials/


Dyeing can be a little messy, but the colours you can achieve by mixing natural cloth with colours from Mother Nature are well worth it. Natural dyeing is simply the process in which yarn or fabric is immersed in a solution produced by boiling up selected raw materials, or dye-stuffs. These may be from an animal, vegetable or mineral source.
Natural dyes are a renewable resource – almost every plant in the world will give a fantastic colour and they are literally on your doorstep. If they’re not free, they can be created inexpensively or are the waste product of cooking or gardening. Dyeing with natural dyes has obvious ecological advantages – no chemicals, no nastiness. But they also create colours that are just magical, so I think the combination is a win-win on both practicality and aesthetics.
There are many books and courses that offer an in-depth education in the art of dyeing. For Cloth, I thought we’d keep it simple – a starting point to something that can become very addictive, very quickly. There are two types of natural dyes. Substantive dyes are those that give a fast, lasting colour without the need for extra chemical processes (or mordants) to fix the colours. Adjective dyes require the yarn or fabric to be treated with a mordant to make it more absorbent and allow the dye to bite and take hold. Different dyes use different mordants, but most mordants are mineral based – such as alum, tin, chrome or iron. However, the oldest is urine – not very lovely to think about, but very effective. Most dyes fall into the second category. If you don’t mind the colour being lighter or fading over time (and possibly bleeding) then you can skip the mordant when heating your water for dyeing. A simple mordant to use on all natural cloth is alum – readily available in a salt form. The simplest option is probably common table salt.
To dye fabric you need to bring water and your choice of dye to the boil, reduce to a simmer and then add the mordant. After concocting the mixture, add the fabric and then allow it to soak in the dye. The longer the soak, the more intense the colour. Once you have the colour you’re aiming for, remove the fabric and rinse it in lukewarm water until the water runs clear. Then hand wash it with a gentle detergent. The final colour will vary depending on whether you use fresh or dried dyes, whether the water is hot or cold, what fabric you use, the type of mordant and the pH level of the water. In addition, every natural cloth will take dye differently as some fabrics are protein based and some plant based. This sounds very complicated but it isn’t. I like a slight sense of ‘winging it’ when I dye, but you can always use scraps of cloth to test colour.

Dye-stuffs

Here is a list of plants, berries, bark, leaves and powders that are perfect for dyeing. Have a rummage in your pantry or wander through your garden and neighbourhood to find the perfect colour.
Useful equipment for dyeing
:: Metal pots or saucepans (only to be used for dyeing)
:: Tongs
:: Stirrers or sticks
:: Insulated rubber gloves – from a DIY store
:: A couple of buckets or plastic containers
:: Pegs, clips and rubber bands
:: Glass jars for mordants to keep them safe
:: An apron or a selection of old clothes
:: Alum salts
:: Your choice of dye-stuff
