Abstract: A chrome-free tanning process of an ecological leather is characterized by a TWS+sodium lignosulfonate+TWLZ ternary tanning process system. The sodium lignosulfonate added can not only have a fixation effect on a TWS tanning agent to make the TWS tanning not undergo detanning at a low pH, but also significantly improve the uniformity of distribution of a TWLZ tanning agent in a hide/skin and promote the formation of a stable cross-linked network structure by the TWLZ tanning agent in a collagen fiber, which effectively overcomes the defects of tanning performance of the existing tanning systems to obtain a leather with uniform and sufficient tanning, a high isoelectric point, a strong electropositivity, excellent absorption for post-tanning chemicals, and a prominent softness, and gives a leather a wide use range and a high quality.

Abstract: A fall protection apparatus has a first cover plate and a second cover plate opposite each other; a rope clamping member located between the first cover plate and the second cover plate and provided with a limit groove as well as a locking position and an unlocking position; a shifting button having a first end connected to the rope clamping member and a second end penetrating through the first cover plate and partially exposed from the first cover plate; and a brake assembly including a pressing portion, a connecting portion, and a brake portion that are connected sequentially.
