The invention relates to a shirt stay-typed collar, a main stitching method of which is that a lapping cloth-typed stay is embedded close to the collar point of a shirt to obtain the supporting effect of reinforcing the collar and keeping the collar point to be sturdy. After a plurality of times of washing, the whole collar, especially the collar point can still keep the appearance effect of roundness, smoothness, flatness and stiffness and the bad phenomena that the collar point bends to the bottom surface of the collar or curls to the front of the collar cannot happen; at the same time, compared with the prior art, the operation method is easier and simpler; at the same time, the operating method is simpler and easier to carry out compared with the prior art; furthermore, the positioning of the stay is more accurate and firmer, the problems of shifting or malposition cannot appear, thus reducing the influence of the tip part of the stay on the water-resistant performance of the collar point which is not easy to be washed to be broken.

The seven-layer coextruded antiswarp composite film with nonsymmetric crystalline characteristics possesses the following structure expression formula: A / B / C / A / B / C, where A is crystalline resin layer, B is adhesive resin layer and C is amorphous resin layer. According to the principle of mechanical equilibrium said invention utilizes the identical charateristics of same kind or same type of materials of design the above-mentioned second layer, third layer and fourth layer into balance bridge structure, and uses said balance bridge structure to counteract the stress imbalance resulted from different crystalline temp. between other layers so as to effectively overcome warp.

The invention reveals a transfer paper manufacture method. The method is characterized in that a surfactant is added, the surfactant is added after pulp refining and before pasting moulding, or the surfactant after pasting moulding is added on the surface of the mould paper by a glue applying mode, and the surfactant comprises an aqueous wax emulsion or a fluorine compound. By adding the surfactant, the paper surface tension is reduced, an off-machine coater is not required, and only a paper machine can be used for completing the transfer paper production, processes can be saved, and the problem of curling of the transfer paper can be thoroughly solved, and the defects that the transfer rate due to ink penetration of the transfer paper produced by the paper machine is low, and the picture and text definition is low can be overcome.

The invention discloses a display panel stripping method, and the method comprises the steps: forming a resin layer and a sealing layer on a light-transmitting substrate, and forming an extension filmon the sealing layer; and stripping the light-transmitting substrate from the resin layer. The technical problem that a display panel is curled and warped when being separated from the light-transmitting substrate can be solved, the flatness of the display panel is guaranteed, and the yield of the display panel is increased.

The invention discloses color printing ink for printing heat shrink film labels and relates to environmental-friendly ink. The color printing ink comprises the following components: acrylic resin, nitrocotton, VINISOL OH, CAB (Cellulose Acetate Butyrate) resin, EVA (Ethylene Vinyl Acetate) resin, a color pigment, additives and a diluent, wherein the additives are polyethylene wax and fumed silica. Compared with the prior art, the color printing ink for printing the heat shrink film labels, disclosed by the invention, has the advantages that the color printing ink is free of benzene and ketone, resists tetrahydrofuran and can be applied to PVC (Polyvinyl Chloride), PET (Polyethylene Terephthalate), OPS (Oriented Polystyrene) heat shrink film base materials, and after the color printing ink is matched with heat shrink films for printing, the shrink films do not curl and are free of tinting. The products printed by adopting the color printing ink are in line with environment-friendly requirements, are safe and non-toxic and can be recycled; and after printing, the shrink films have very strong capability of resisting alcohol and tetrahydrofuran, thus the problem of the compatibility between the thin films and glue occurring when the thin films are subjected to skin packaging and are glued is solved very well.

Embodiments of the present invention provide a flexible substrate and a manufacturing method thereof, which relate to the field of display technology and solve the problem of unnecessary curling when the flexible substrate is peeled off from the carrier substrate in the manufacturing process of the existing display device problems, avoid damage to the performance of the display device, improve the display quality of the display device, and prevent the final product from becoming a defective product. The flexible base substrate is formed of a flexible material, and the base substrate includes: a first flexible film layer, wherein: a plurality of grooves are arranged on the lower surface of the first flexible film layer; the grooves have the same thickness. The invention is applied in the manufacturing technology of the flexible base substrate.
