Disclosed is a pumping method of a large-diameter horizontal pressurized long dewatering well for inexhaustible pumping strata. Clay layers and sand soil layers are determined according to construction positions of foundation pits, horizontal holes are drilled in the sand soil layers with a drill rig with simultaneous casing, and after the designed depth is reached, horizontal wells are placed, the horizontal wells are located above the junction of the clay layers and the sand soil layers, and the horizontal wells comprise drain pipes and air ducts, the drain pipes and the air ducts are located at the same elevation, each air duct is located between the two drain pipes, and the air duct is connected with the air pipe of the air compressor to deliver and pressurize, so as to facilitate water in the strata of aquifer to gather into the drain pipes.

A process for treatment of cellulosic material, for example, knitted or woven cotton fabric or yarn, comprises treating cellulosic material with a pectinase and a surfactant.

Enzymatic treatment of cellulosic textile

A method for treating dyed textile, comprises contacting the dyed textile with a pectolytic enxyme, wherein the said method is not applied during the abrasion stage when the dyed textile is a denim fabric.

Color modification of textile

Provided is an enzymatic treatment on polyester/cellulose blend textile by contacting the textile with a cutinase and preferable with cellulose as well.

Method of treating polyester textile

The use of a peroxidase, a source of hydrogen peroxide and a mediator for providing a modified color in the textile is described.

The present invention relates to the method for manufacturing textile, by treating textile with an isolated polypeptide having endoglucanase activity, especially in biostoning and bio-polishing process.
