A method of making a lightweight foamed recycled leather is described. The method includes pulverizing the collagen fiber waste generated in a controlling a thickness of the leather during a leather process; neutralizing the resultant of step (a) by a soda ash with a water; (c) dyeing and fat-liquoring process treating the resultant of the step (c); (d) mixing a latex, a dispersant, a coagulant, and a thermally expandable microspheres with the resultant of step (c); (e) coagulating a collagen fiber powder and the latex by adding a coagulant into the resultant of step (d); (f) dehydrating and drying the resultant of step (e); and (g) heat treating the resultant of step (f) to foam thermally expandable microspheres, thereby to impart functionality to the recycled leather.

Method for manufacturing lightweight foamed recycled leather and recycled leather produced by the method thereof

A seed planter capable of removing soil, which is capable of: forming holes in which seeds can be planted by applying downward pressure to soil furrows covered by vinyl and by removing the covered vinyl and soil all at once, and at the same time inserting a supply pipe into the formed holes such that the seeds, water, and a fertilizer can be selectively placed therein; enables the removed covered vinyl at a fixing pin and within a needle member; and has a measuring tape such that holes can be precisely formed at proper intervals for growing plants.
