wool question

[brian]

reading up on hunting clothes, and being bloody cold over here ATM has led me to this question. alot of people say wool is better in cold/wet weather because it stays warm even when wet. if this is the case, then what is the actual reason it stays warm when other materials apparently dont?

The air that is trapped between the fibres,warms up by your body heat, acts as a buffer to the cold.

er yes, but..... all insulating materials such as cottons and polyester do this, but are apparently NOT warm when wet.

Maybe because to a certain degree due to the Lanolin in wool it is waterproof . Just look at a wet sheep ,, spread the wool apart and he will be dry underneath :wink:


ah - now there is an answer i'll put my money on. :wink: good one coach - that makes sense to me.

thanks for the replies fellas. :D

dont give coach the loot yet! :D i read somewhere that wool fibres are hollow. that would cause them to trap or hold heat even when wet. there are synthetics available now that are lighter, dry quicker, and conserve heat better than wool. :D you will pay for them but. hope this helps.

[brian]

interesting - if thats the case then i'll back both you with even money.

are there any synthetics with hollow fibers? i imagine manufacturing hollow fibers would be difficult/expensive.

I know I've been caught in the rain with a woolen jumper on, they do get wet.

Wool stays (relatively) warm when wet because it doesn’t absorb water into the fibres like cotton and the natural oils allow it to shed water from between the fibres.
The insulating properties of wool (and other fibres of a similar nature) come from the air trapped between the fibres. Although very course merino wool (and foreign wools like llama and dorper) does have some hollow fibre (called medullation), fine wool does not, and in fact a great value is placed on wools with no medullation as it dyes with a better consistency.

Polarfleece, made from recycled PET bottles has the same properties, although in it’s case the ability for the fibres to resist absorbing moisture is because it is plastic.

WOW jindy. :shock: i wish i'da said that! :lol:

always reliable - and well studied it seems. thanx jindy.
