The present invention provides a hard coating film comprising: a substrate; a first hard coating layer formed on one surface of the substrate; and a second hard coating layer formed on the other surface of the substrate, wherein the first hard coating layer includes a cross-linked polymer of an oligomer having an elongation of 50 to 350%, the second hard coating layer includes a cross-linked polymer of an oligomer having an elongation of 0.1 to 50%, and the crosslinking density of the first hard coating layer is smaller than the crosslinking density of the second hard coating layer, and a flexible display having the hard coating film. The hard coating film according to the present invention has excellent impact resistance and curling properties and also has excellent bending resistance.

The invention relates to a full interposition aromatic polysulfonamides fibre production method, which includes three steps: the spinning serous producing, wet method spinning and post treatment. The spinning serous producing includes the following steps: dissolving 3' 3-diaminodiphenyl sulphone in an organic polar solvent, cooling to -20-20 EDG C; adding metaphenylene dimethylamine acyl with the same molecular of 3' 3-diaminodiphenyl sulphone for executing polymerization reaction; and then adding inorganic base with the same molecular of 3' 3-diaminodiphenyl sulphone for executing neutralization reaction with the hydrogenchloride produced in the polymerization reaction, thereby manufacturing spinning slurry with 10%-20% of dry content. The fabre obtained by the invention method, has largely improved curl performance compared with the conventional aromatic polysulfonamides fibre, obviously improves the elongation at break and improves the resultant yarn leptogenesis.

Disclosed herein is a UV surface-coated laminate wood flooring for an under-floor heating system comprising a back-grooved base, an adhesive layer and a printed wood veneer layer wherein the printed wood veneer layer is produced by impregnating and coating a low-basis weight printed paper with a thermoplastic or thermosetting resin, integrally forming the paper layer with a low-price reinforcing layer by pressing under high pressure, treating the surface of the paper layer with an acryl based primer, and coating the primer-treated paper layer with a solvent-free type UV coating paint, and wherein the back-grooved base and the printed wood veneer layer are adhered to each other by the adhesive layer.

The present invention relates to a hair iron which can reduce hair damage while forming straight or curled hair. According to an aspect of the present invention, disclosed is a hair iron configured to allow hair to pass between a first heating body and a second heating body formed to extend along the front and rear direction, the hair iron comprising: a first heating body which includes a first central part configured to have a plate-shaped surface extending along the front and rear direction, and a comb tooth protrusion part in which a plurality of comb teeth protrusions having ridges which extend and protrude along the lateral direction of of the first heating body are arranged symmetrically on the left and right sides of the first central part along the front and rear direction of the first heating body; and a second heating body which includes a second central part configured to have a plate-shaped surface extending along the front and rear direction, and a receiving groove part in which a plurality of protrusion receiving grooves for receiving each of the comb teeth are arranged symmetrically on the left and right sides of the second central part along the front and rear direction of the second heating body.

The invention relates to the field of cable manufacturing equipment, in particular to cable manufacturing equipment. The cable manufacturing equipment comprises a supporting structure, a dust removingstructure, a telescopic structure, a winding structure, a height adjusting structure, a guide structure and a conveying structure, wherein the height adjusting structure is arranged inside the supporting structure, the end part of the height adjusting structure is connected with the winding structure, the winding structure and the supporting structure are connected in a sliding mode, then the winding structure can be driven to slide on the supporting structure through the height adjusting structure, and then winding frames with different diameters can be fixed conveniently, so that winding ofcable frames with different diameters is facilitated, and the winding flexibility is greatly improved; and the dust removing structure is arranged at the end part of the telescopic structure, then after the position of the dust removing structure is adjusted, cables are limited and guided through the dust removing structure, meanwhile, cooling and dust removal of the cables can be conveniently carried out again, so that the packaging of a heat shrinkable film is influenced at the later stage caused by too high temperature is avoided, and meanwhile, the dust and sweeps are prevented from beingadhered to the cables.
