The method of storage fur and wool
(57) Abstract:The invention relates to the storage of products and materials, and in particular to methods of storage and protection of fur and charlesdarwin fibrous materials from ceratapion /larvae of the moth and cojiedo/, mildew, and other pests. The essence of the invention lies in the fact that fur and wool are placed in a chamber filled with nitrogen gas with a relative humidity of 65% at ambient temperature. The invention relates to the storage of products and materials, and in particular to methods of storage and protection of fur and charlesdarwin fibrous materials from ceratapion (larvae of moths and cojiedo), mold and other pests.Insects that feed on keratin (hair, fur), live in damp dark places, therefore, the greatest damage to wool and fur get when stored in warehouses.There is a method of keeping the skins in a closed chamber with a germicidal environment.The disadvantage of this method is the impossibility of long-term storage of furs.The solution environmentally friendly effective universal protection of fur and wool from pests during storage can be implemented using the Delia of them (raw materials in bales, cloth, shoes, clothes, felt), placed in a chamber which is filled with gaseous nitrogen with a relative humidity 655% and stored permanently in a nitrogen atmosphere at ambient temperature.The technical result is achieved in that in an environment of nitrogen gas cannot exist in any living organisms, which for the normal functioning of the necessary oxygen.In the environment of liquid nitrogen ceases functioning of all pests, so you may secure storage fur and wool at ambient temperature and do not require expensive, difficult to manufacture, and operation of refrigeration equipment. Nitrogen neutral organic gas. Relative ambient humidity of 65% ensures the preservation of the condensation wool fiber, fur and articles thereof. The method allows to increase efficiency and reduce storage costs while maintaining the quality of stored products and materials and simplifying maintenance stores. The method of storage of furs and fur in the camera with a germicidal environment, characterized in that as a germicidal environment using nitrogen gas with a relative humidity of 65 5% and storage is carried out at the pace of the
FIELD: tannery industry.
SUBSTANCE: claimed method includes treatment of chrome-tanned semi-finished product with antiseptic such as polymineral obtained from natural non-metal fossils (minerol), which is used in amount of 5-10 mass % based on semi-finished product. Minerol is also used as filler being introduced in retanning step with chrome compounds in amount of 5-10 mass % based on semi-finished product.
EFFECT: effective biological leather conservation after chrome tanning.

SUBSTANCE: modified leather is meant for making internal components of shoes with good biocidal properties and relates to light industry. The modified leather includes a collagenic base with a multilayer structure, tanning, retan, oiling compounds and a biocidal additive, the later being in form of silver nanoparticles and alkyldimethylbenzyl ammonium chloride in ratio of 1-:-0-1.5 respectively. Content of silver nanoparticles is 7×10-5 - 6.4×10-3 wt %.
EFFECT: wide range of lining leather while cutting on number of biocidal agents used on the leather and stabilisation of deformation-strength characteristics of the leather during its use, as well as improved environmental friendliness of the process of manufacturing said leather.
FIELD: veterinary science.
SUBSTANCE: method consists in fur treatment with acoustic (audible) sound of certain frequency in the range of 20-20000 Hz, its intensity varies in the range of 10-100 dB for the time of treatment in the range of 1-10 min.
EFFECT: reduced toxicity of treatment.
