The vegetation pad that the present invention relates to a kind of for manufacturing biodegradable loess yarn and the spinning of degradable loess are thus, the wherein degradable composite plastic for being produced by melt spinning and elongation of the vegetation pad of biodegradable yarn, it is main component that it, which is by degradation plastic (PLA), biodegradable plastic loess composition is by being added loess powder, it is sintered and has crushed by being ground to degradable composite plastic, it is elongated with degradation plastic loess composition, while is being meltblown. The vegetation pad of biodegradable loess yarn, it be by it is a kind of manufacture loess yarn vegetation pad, according to the present invention, can natural decomposition scheduled time span can be used as base manure decompose after,By the way that loess powder and degradable composite plastic is added, degradation plastic (PLA) is main component. In addition, the present invention can crush loess fine smash and grind passed through by the loess that is sintered it is one or many, and the uniformly mixed particle of loess powder can be crushed by heating loess powder and milling machine when broken loess, therefore dusting loess, while removing moisture and penetrating into loess powder. Therefore, the loess powder of crushing can be equably in the raising of biodegradable plastic composition and loess yarn qualities. ;The 2014 of copyright KIPO submissions
