| Studied ancient Chinese history but not a silk expert, here's my
| 2c.
|
| Critical background is that silk takes a lot of labour to
| prepare. First you must have the right kind of insects (various
| species of moth in the larval stage are commonly known as
| "silkworm"), then you must have the right kind of trees to feed
| them (commonly mulberries), then you add a lot of labour for
| capture, harvesting, spinning, dyeing, weaving. In modern times I
| have only really seen it prepared commercial scale in Jiangsu
| province (near Xuzhou). If you head too far north the insects
| probably suffer from the cold, and if you head too far south any
| artificial farming monoculture is probably readily outcompeted by
| other flowering plants and predatory insects which are more
| suited to the tropics (on account of higher moisture, food
| availability and temperature).
|
| Relative to existing fabrics such as hemp, silk has at least in
| other contexts been of value militarily because of its relative
| strength to weight ratio and dense weave when applied to
| important tasks such as resisting arrows, although I'm uncertain
| if this use had emerged yet. Any military use would tend to
| reinforce a cultural link between life and death owing to its
| spatiotemporal proximity to mortality events.
|
| The fact that it is soft and labour-intensive (expensive / in
| short supply) means it was probably reserved for the wealthier or
| higher ranking figures.
|
| Although the paper doesn't state it clearly, it actually deals
| with the archaeological findings of a _non-Han Chinese_
| civilization in the area of Sichuan which was illiterate and was
| based around what appeared to be a bird and tree cult (the Shu
| kingdom of the Sichuan basin[1]). It is therefore possible that a
| kind of soft, reflective-refractive, feather-like, readily dyed
| textile with a fine weave may have contributed to some sort of
| ritual purpose in line with these beliefs. Later this
| civilization was destroyed by the Han Chinese.
|
| The wicking properties of silk are fair (I was unable to find a
| quantitative reference) as was the major early textile of hemp
| (which is also tough and therefore long-lasting) which is
| significant as we know that Sichuan in the Shu kingdom period was
| a vast, tropical inland basin criss-crossed by regularly flooding
| rivers descending from the Himalayas, thickly forested and with
| crocodiles, elephants, rhinos, giant cats, colourful birds, etc.
| Both silk and hemp textiles would help to cool anyone wearing
| them, relative to other options (animal skins, etc.).
| Furthermore, in the absence of modern medicine, fine-weave
| capable wicking fabrics would assist with resisting potentially
| lethal bacterial and fungal infections in the tropical
| environment and may therefore have been used as wound dressings
| or undergarments.

| Silk's just easier in general. Unlike vegetable fibers, silk
| can be reeled to yarn/thread directly. With cotton (or wool),
| there are about 4-6 other processes before you can even get to
| spinning. Hemp's worse still, I think there's a retting process
| in there like with linen.
|
| Or perhaps, it's more true that the labor-intensive portions
| are up front... you're feeding the dumb little worms up to 4
| times a day early on, transferring them off of the eaten leaves
| (so as to avoid disease), and this only lightens up to twice a
| day later in the lifecycle. And this isn't tapping out a little
| pinch of food like for a goldfish bowl, they'll often do 10,000
| worms at a time just to have some modest quantity of fiber
| (perhaps enough for 5 or 6 yards of fabric). This ends up being
| like 60+ lbs of mulberry leaves there at the end.
|
| All told though, I'd much rather raise the worms than sit there
| for six months trying to card cotton by hand.

|
| Considering how little regard we have for what was

| *EDIT: Perhaps a better way to say this: the ultimate
