The invention discloses a preparation method of superfine fiber high-imitation grain synthetic leather. The preparation method comprises the following steps of: spinning sea-island composite fibers by utilizing nylon 6 and low-density polythene as raw materials, manufacturing non-woven fabric by utilizing the sea-island composite fibers, coating one surface of the non-woven fabric by utilizing high-solid-concentration polyurethane slurry, infiltrating the non-woven fabric by utilizing low-solid-concentration polyurethane slurry, enabling the non-woven fabric to pass through an aqueous solution of dimethylformamide after infiltrating, solidifying polyurethane and forming a cellular structure to obtain synthetic leather semi-finished products, enabling the synthetic leather semi-finished products to pass through methylbenzene to separate sea-component low-density polythene out of the sea-island fibers, peeling off the sea-island composite fibers to be superfine fibers, washing away methylbenzene through boiling water, and drying to obtain the superfine fiber high-imitation grain synthetic leather. The product manufactured by the method disclosed by the invention has the advantages of strong gradient, abundant hand feeling, fine and smooth surface wrinkles and strong toughness after being bent, and has the beneficial effects on aspects of pollution reduction, animal protection, ecological protection and the like.

A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on fibrous mat of non-woven fabric. The TPU coating contains a barrier layer to retard the migration of styrene from the liner to the media used to force the liner against the damaged pipe and to activate the thermoset resin. The thermoset resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe.

The invention relates to a non-woven fabric winding and cropping combined device. The non-woven fabric winding and cropping combined device comprises winding equipment and cropping equipment which coordinate with each other. The winding equipment comprises a supporting frame. The cropping equipment comprises a material carrying assembly and a cropping assembly, wherein the material carrying assembly comprises a roll shaft frame and a plurality of first tension adjusting rollers, the roll shaft frame is installed on the supporting frame and extends towards one side of the supporting frame, andthe multiple tension adjusting rollers are rotationally installed on the roll shaft frame; and the cropping assembly comprises a supporting vertical plate, an abutting roller, a plurality of second tension adjusting rollers, an extending plate and a plurality of sets of cropping cutters, the supporting vertical plate is arranged on one side of the material carrying assembly and corresponds to theroll shaft frame, the abutting roller is installed on the side face of the supporting vertical plate and is perpendicular to the supporting vertical plate, the multiple second tension adjusting rollers are installed on the side face of the supporting vertical plate and located between the abutting roller and the roll shaft frame, the extending plate is installed on the side face of the supportingvertical plate and located over the abutting roller, and the multiple cropping cutter sets are arranged on the side face of the extending plate in a lifting manner and are arranged at intervals. The non-woven fabric winding and cropping combined device can wind non-woven fabric and crop the non-woven fabric in the length direction, and the production efficiency of the non-woven fabric is advantageously improved.

The invention discloses a puncture-resistant structural layer and an application thereof to preparation of puncture-resistant gloves. The puncture-resistant structural layer is puncture-resistant woven fabric, a plastic sheet, coated fabric or plastic composite fabric; the coated fabric comprises base cloth and a coating applied to the surface of the base cloth, and the base cloth is the puncture-resistant woven fabric; the plastic composite fabric is a sheet layer prepared from a plastic base material and the puncture-resistant woven fabric by high-temperature pressing. The puncture-resistantstructural layer is soft and has quite strong puncture-resistant and anti-cutting functions; the puncture-resistant gloves prepared from the puncture-resistant structural layer have excellent dexterity and comfort while realizing the puncture-resistant and anti-cutting functions.

The invention relates to a roll cover for treating a paper, cardboard, tissue or other fibrous web in a machine for manufacturing and / or converting them, comprising one or more plastic layers, of which at least one is of compressible configuration, and at least one carrier element in the form of a woven fabric, laid scrim or the like. Here, the loading of the support structure is intended to be reduced by at least one carrier element being embedded into a compressible plastic layer.
