摘要： The invention relates to leather for furniture and automotive upholstery and protective footwear, surface finished with titanium dioxide nano particles doped with 10% silica with an average particle size of 46 nm and with self-cleaning properties and improved resistance to heat transmission and combustion. The process for obtaining leather with self-cleaning properties and resistance to heat/fire consists in applying the base coat containing 0.05-10% titanium dioxide nano particles (% relative to the amount of binder) doped with 10% of silica which are dispersed in an equal amount of polyethylene glycol 600 and, according to another variant, 0.01-15% sodium polyacrylate, by mechanical stirring for 10 minutes, followed by sonication for 5 minutes, with pigment paste based on macro titanium dioxide, water and acrylic binder. This composition is applied by spraying in successive coats with intermediate drying and final pressing at 110°C and 20 kgf, followed by fixation with nitrocellulose lacquer in successive coats, with intermediate drying and final pressing in the same conditions. Self-cleaning properties are provided through photocatalytic degradation of organic dirt under the influence of ultraviolet and visible light and resistance to heat transfer and combustion.

摘要： The invention relates to a composition based on dolomite or limestone and collagen hydrolysate and to its application in encapsulating legume seeds in order to obtain full spherical and durable coatings that stimulate germination, increase biomass and resistance of plants to drought. For this purpose, for coating 1 kg of legume seeds, 150-400 g dolomite or limestone and 9-34 g collagen hydrolysate are mixed in a disc-type granulator, at an angle of 45° and a rate of 20 RPM. The method of extraction collagen hydrolysate allows for obtaining a product with 30% dry substance, molecular weight of 16000 Da, binding properties for encapsulation composition and biostimulating for legume seeds and seedlings and consists in alkaline hydrolysis with 10% calcium oxide, decanting, filtration, enzymatic hydrolysis with 0.4-1% Alcalase 2.5L, followed by advanced refining by decanting, vacuum concentration at 70°C, decanting and filtration.

摘要： The invention relates to a process for the conservation of raw hides, wet-blue or crust leathers by irradiation with gamma radiation, at a dose of 25 kGy, as an ecological alternative for the use of sodium chloride and organic biocides, potentially toxic for the environment. The process, according to the invention, consists of sealing hides in polyethylene bags and introducing them into the SVST Co-60/B irradiator, with sources of Co-60 of 100,000 Ci, for 12 hours, at a temperature of 18°C, during which the samples rotate around the irradiation source until the 25 kGy dose is accumulated. The hide thus treated is sterile immediately after irradiation and 28 days after treatment and shows minimal physico-chemical changes, compared to the classically treated hide.

摘要： The invention relates to leather with antimicrobial and self-cleaning properties in the visible domain, surface-finished with nitrogen-doped titanium dioxide nanoparticles and 1.6% nano silver deposits with a mean particle size of 30 nm. The process for obtaining antimicrobial and self-cleaning leather consists of the application of a base coat containing 0.01-8 g/L nitrogen-doped titanium dioxide nanoparticles and 1.6% nano silver deposits dispersed with 0.001-8 g/L of sodium polyacrylate by mechanical stirring for 10 minutes followed by 5 minutes of ultrasonic stirring with pigment paste, water and acrylic binder. This basic composition is applied by spraying in successive layers with intermediate drying and ironing at 110°C and 100 kg/cm 2 followed by fixing with nitrocellulose lacquer in successive layers with intermediate drying and final ironing at 110°C and 120 kg/cm 2 . Antimicrobial and self-cleaning properties are ensured by photocatalytic degradation of organic dirt under the influence of visible light.

摘要： The invention relates to a product based on collagen polydispersions used for cereal seed treatment in order to stimulate growth, reduce the intake of pesticides and the process of manufacturing thereof.
Extraction of collagen polydispersions from leather waste occurs in two phases carried out through a compact process in the first phase through alkaline hydrolysis of chrome tanned leather waste, with 8-12% calcium oxide, or thermal hydrolysis of rawhide waste, at a solid/liquid ratio of 1/4, at a temperature of 70.....85°C, stirring for a period of 3.....5 hours and static until the next day without thermal input, followed by enzymatic hydrolysis with enzymatic preparation Alcalase 2.4L in concentration of 2.5.....4.5 enzyme units/total nitrogen gram, at a temperature of 63°C ± 2°C continuously stirring for 3.....5 hours for tanned leather waste, and static until the next day without thermal input in the case of extraction from rawhide waste. This process enables protein mass recovery in a proportion of 85.....95% and cleavage of peptide chains, yielding collagen polydispersions containing free amino acids, with average molecular weight of 4000-6000 Da for systemic cereal seed treatment, with effects on stimulating germination and increasing resistance to insect and fungal attacks.
