The present invention provides a method of manufacturing leather, which not only significantly suppresses the occurrence of adhesive wrinkling and boarding/alighting wrinkling when used for an automobile seat, for example, but also exhibits appropriate flexibility. The present invention is a method of manufacturing leather including a pretreatment step, a tanning step, a retanning step, and a drying and finishing step in this order, the retanning process including, in the following order, subjecting a shaving leather obtained from the tanning process to a stage of performing treatment using a predetermined retanning agent and a predetermined resin, a stage of performing treatment using a predetermined retanning agent, a predetermined resin, and a predetermined fatliquoring agent, and a stage of performing treatment using a predetermined resin and a predetermined fatliquoring agent, and the drying in the drying and finishing process including, in the following order, subjecting a leather obtained from the retanning process to a stage of drying under reduced pressure under predetermined conditions and a step of drying at atmospheric pressure under predetermined conditions.

The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection infrared range of the electromagnetic spectrum reduce heating by sunlight in the near infrared dark tinting in the visible range. Low density conductivity are obtained inter alia by inserting in the near in order to area despite and low heat light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.

Present invention related to method of washing and finishing leather, canvas, cotton and any other material, as well as the finished products such as, but not limited to shoes, bags, accessories, clothing, denim, T-Shirts, and components of these products by washing in brewed coffee. Material, for example leather, canvas, cotton, denim, washed in coffee before manufacturing the product.

The present invention relates to N-acylmorpholines as solvents for use in processes for preparing polymer dispersions.

Compositions containing an aminoalkyl-containing polydimethylsiloxane, a silicon compound containing silicon-bonded alkoxy groups, and a zirconium, titanium, or zinc carboxylate catalyst provides water repellency and stain resistance to substrates, particularly woven and non-woven textile and leather substrates.

The present invention discloses a process for preparing a flame-retardant, lightfast, low fogging and degradable car seat leather wherein ammonia salt deliming is replaced with an ammonia free one, tetrakis hydroxymethyl phosphonium sulfate and the flame-retardant starchy leather surfactant are used as the tanning agents to replace the conventional chrome tanning agent, hot water washing is used to reduce the fogging value of the seat leather, the flame-retardant performance is enhanced by combination of retanning, greasing and coating, the lightfast material is applied to enhance the lightfastness of the coating and the spray coating is replace with the roller coating to lower the consumption of the paints.

A process for the production of coated textiles comprises the steps of: providing a textile substrate having a first side and a second side opposing the first side; contacting at least a part of the first side of the textile substrate with a spreadable polyurethane mechanical foam; applying a reduced pressure to at least a part of the second side of the textile substrate opposing the first side which has been contacted with the polyurethane mechanical foam; and solidifying the polyurethane mechanical foam with which the textile substrate has been contacted. The invention further relates to a coated textile obtainable by such a process, in particular a synthetic leather.
