Definitions

  • the synthetic oil and / or natural oil (c1) constituting the greasing agent (c) exists as an O / W type emulsion, and the shape of the oil droplet of the oil (c1) is substantially an ellipsoidal sphere.
  • the leather manufacturing method described in (1) above (3) The method for producing leather according to (2) above, wherein the number of oil droplets having a substantially ellipsoidal shape of the oil (c1) is 60% or more of the total number of oil droplets.
  • the number of oil droplets having a substantially ellipsoidal shape of the oil (c1) is 90% or more of the total number of oil droplets.
  • Synthetic oil and / or natural oil (c1) is used as the greasing agent (c) used in the greasing treatment in step (III-1).
  • a mixture of synthetic oil and natural oil is used.
  • the mixing ratio of both of these is not particularly limited, but preferably, the mass ratio of synthetic oil: natural oil is 0.4 to 0.6: 0.6 to 0.4.
  • the oil (c1) preferably exists as an O / W emulsion, wherein the oil (c1): water mass ratio is preferably 1: 4 to 1: 6, more preferably 1: 4. It is .5 to 1: 5.5, and is usually about 1: 5.
  • the number of oil droplets having a substantially elliptical sphere shape is the number of the total number of oil droplets. It is preferably 60% or more, more preferably 70% or more, still more preferably 80% or more, and even more preferably 90% or more.
  • the shaving leather treated as described above is further subjected to the resin tanning treatment using the resin (b) and at the same time the greasing treatment using the greasing agent (c). Be done.
  • the resin (b) as in the above steps (III-0) and (III-1), a polymer consisting of one selected from the group consisting of acrylic acid, methacrylic acid, acrylate ester and methacrylic acid ester, or a polymer thereof.
  • the amount of each substance added in the step (III-0), the step (III-1) and the step (III-2) is less than the range of the present invention.
  • Five pieces of shaving leather (moisture: about 55% by mass) were charged, and in the retanning treatment of step (III-0), 6.3 parts by mass (total) of the retanning agent (d1) chromium and (d2) glutaraldehyde were added. 12.6 parts by mass) and 6.2 parts by mass of Relugan RV as the resin (b1) were added, and in the retanning and greasing treatment of the step (III-1), Ukatan GM was added as the retanning agent (a1).
  • FIG. 10 shows an example of a photograph showing each of the above-mentioned 1st to 5th grade criteria.
  • the grades 1 and 2 are sequentially from the top on the left side, and the grades 4 and 5 are sequentially from the top on the right side. Almost no wrinkles can be seen in the first-class photographs.
  • Comparative Example 9 did not add the retanning agents (d1) chromium and (d2) glutaraldehyde to Example 1 in the step (III-0), and Comparative Example 10 was carried out. Only (d1) chromium was added to Example 1, and Comparative Example 11 was obtained by adding only (d2) glutaraldehyde to Example 1. In both cases, the evaluation of adhesive wrinkles and boarding / alighting wrinkles was extremely poor.
