The disclosure provides embodiments of environmentally acceptable fishing lines or fishing nets. Embodiments of the disclosed fishing line or net may comprise a degradable polymer having components derived from i) biomass sources, ii) protein, fatty acid or lipid sources, iii) microbial-based monomers and polymers, iv) agro-based monomers and polymers, v) sugar or starch based monomers and polymers, or combinations thereof, as well as fishing lines and net that further comprise an additive having components derived from i) polyol sources, ii) citrate sources, iii) fatty acid sources, iv) biomass oil sources, or combinations thereof. Some of the embodiments of the disclosed fishing lines or nets may have a suitable fiber core, while other embodiments of the disclosed fishing lines or nets are degradable over a predetermined period of time. The disclosed embodiments are preferred because of the low environmental impact of the disclosed fishing lines or nets when compared to, for example, well known synthetic polymer fishing lines or nets.

The present invention provides a knitted fabric with leather fibers comprising a ground yarn layer and a face yarn layer directly connected with the ground yarn layer through double knitting. The ground yarn layer includes a plurality of first yarn loops, each of the first yarn loops is formed by a plurality of ground yarns. The face yarn layer includes a plurality of second yarn loops, each of the second yarn loops is formed by at least one face yarn attached with the leather fibers obtained from a piece of leather by a pulverization operation. A course ratio of the face yarn layer to the ground yarn layer is in a range between 1:1.25 and 1:4. Accordingly, the invention provides an innovative knitted fabric and solves the problem that the leather cannot be recycled after being discarded.
