  • Publication number: 20100288962
    Abstract: Various fluoropolymers have been proposed for imparting oil and water repellency to leather. Commonly, these fluoropolymers are amphiphilic; i.e., they are made from at least one monomer which is hydrophobic and at least one monomer which is hydrophilic. The present invention identifies and remedies disadvantages associated with the ability of amphiphilic fluoropolymers to impart oil and water repellency to leather. Contrary to conventional thinking, it has now been discovered that the incorporation of hydrophilic groups in a fluoropolymer undesirably reduces its ability to impart water resistance to leather. Correspondingly, it has also been discovered that a fluoropolymer incorporating fewer or no hydrophilic groups imparts superior oil and water repellency to leather when compared to fluoropolymers incorporating more hydrophilic groups. Therefore, this invention provides fluoropolymers which incorporate reduced levels of hydrophilic groups.

  • Publication number: 20100281622
    Abstract: This object relates to a natural leather which is obtained by forming a coating film through the greasing step following re-tanning and dyeing and the drying step. The purpose of this object is to provide a natural leather, wherein the generation of free formaldehyde and acetaldehyde is inhibited, and a treating agent to be added in the greasing step for natural leather. A natural leather wherein formaldehyde and acetaldehyde generated by a tanning agent, a re-tanning agent, a dye and a greasing agent having been incorporated into a leather are confined in the leather with a treating agent to be added in the greasing step for natural leather which contains a hydrazide compound optionally together with sodium hydrogen sulfite to thereby inhibit or prevent the generation of formaldehyde and acetaldehyde, and an automobile interior part coated with this natural leather.

  • Publication number: 20100068541
    Abstract: The present invention provides aqueous flesh coating compositions comprising one or more aqueous acid-functional acrylic or vinyl copolymer and from 0.03 and up to 1.0 equivalent, based on equivalents of carboxylic acid in the polymer, of one or more active compound chosen from an aminoguanidine, semicarbazide, dihydrazide, guanamine, hydrazine and a salt thereof. Further, the invention provides methods of applying the coating composition to leather crust or to tanned leather, and to the flesh coated leather or coated leather crust produced thereby. The leather crust and tanned leather produced by the invention, for example fleshcoated or finished leather, will emit greatly reduced levels of aldehydes over time and especially valuable in scrubbing aldehydes from perforated leather for automotive use.
