A method for making an elasticised yarn includes feeding a roving made of a cotton-based natural fibre at a weight percentage of at least 50% and having a linear mass density between 0.1 Nm and 50 Nm, to a stretching unit, and extracting it from the stretching unit at a speed higher than the unwinding speed. The stretched roving and an elastic fibre are jointly pulled through an overlapping unit, forming a spool of the elasticised yarn. The elastic fibre includes a natural rubber containing more than 80% polyisoprene 1,4-cis. The elastic fibre also includes sulphur as a vulcanization agent; a vulcanization accelerator and a vulcanization activator; an anti-tacking agent; an antioxidant agent; and a stabilisation agent. The elastic fibre is obtained by longitudinally cutting a longitudinally cut flat yarn made of the natural rubber, to attain a linear mass density between 50 dtex and 1000 dtex.

The present invention discloses an anti-gravity backpack, which comprises a backpack body and two shoulder straps. A supporting plate is provided on a back of the backpack body, and a pressure reducing plate is provided on a back of the supporting plate. A first elastic band and a length fixing band are provided between the pressure reducing plate and the supporting plate. The existence of the pressure reducing plate, the first elastic band and the length fixing band causes the backpack to bounce up and down to act as a buffer, which not only relieves the pressure on the wearer's shoulders but also saves the wearer's energy with the resilience produced by the elastic band, thus helping slow down the wearer's rate of muscle fatigue and make the wearer feel less burden on the body.
