Vertical conveying channel and uses thereof

A vertical conveying channel, comprising:

• an inner surface and outer surface,
• an inner space that longitudinally extends with at least one end opened,
• the inner surface of the channel is elastic, and an inner diameter of the channel is less than a diameter of an object to be transported along the channel,
• and the object to be transported along the channel is pressed by contracting of the inner surface of the channel during use, to slow down a falling speed of the object;
• wherein, the inner surface of the channel is made of elastic fabric,
• the elastic fabric has a latitudinal elastic deformation rate of 100% to 450%, a latitudinal resilience of 300N to 2500N on condition of latitudinal elongation at break of 80%, a latitudinal elastic recovery rate of 70% to 100%, a latitudinal breaking strength of 800N to 4000N, and a latitudinal plastic deformation rate of 5% to 25%;
• and
• the elastic fabric has a longitudinal elongation at break of 2% to 45%, the elastic fabric has a longitudinal breaking strength of 1500N to 5000N,
• wherein, the elastic fabric is weaved as a latitudinal twofold structure textured in the latitudinal direction, based on 3/1 cross-twill, or is weaved with twill weave, plain weave, or is knitted as a two-side weft-knitted structure with rib-knit.
