DESCRIPTION OF THE PREFERRED EMBODIMENT

[0035] All features or steps in all methods and procedures disclosed in the specification may be combined in any way, except mutually exclusive features and/or steps.

[0036] Any feature disclosed in the specification may be replaced with other equivalent or similar features, unless otherwise specified, that is, each feature is only an example of series of equivalent or similar features, unless otherwise specified.

Example 1

[0037] As shown in the figures, the female die comprises a base, an arm portion, a palm portion and finger portions. The base, the arm portion, the palm portion and the finger portions are connected in sequence as a whole. The arm portion and the palm portion are hollow structures. The finger portions comprise a thumb member, a forefinger member, a middle finger member, a ring finger member and a little finger member.

[0038] A first groove is formed on a palm back member. The thumb member, the forefinger member, the middle finger member, the ring finger member and the little finger member are provided with a second groove at one side of the palm back member respectively, and the second groove is connected with the first groove. The depth of the first groove and the second groove is 0.3-1.5 mm respectively. The area of the second groove on the thumb member, the forefinger member, the middle finger member, the ring finger member and the little finger member is 0.5 time that of the thumb member, the forefinger member, the middle finger member, the ring finger member and the little finger member at one side of the palm back member respectively. Surfaces of the first groove and the second groove are respectively provided with a hydrophilic coating with a thickness of 1-300 m.

[0039] In the example, the female die is made of a Al.sub.2O.sub.3 ceramic material by investment casting, and the contact angle of the surface of the female die is 30-70. The hydrophilic coating is prepared from a TiO.sub.2 ceramic material by plasma spraying. The hydrophilic coating forms a porous water-absorbing surface with a contact angle of 2-30.

[0040] In the example, the thumb member, the forefinger member, the middle finger member, the ring finger member and the little finger member are provided with a second groove at one side of the palm back member respectively, that is, the front half finger back of the finger portions has a normal thickness, and the rear half finger back connected to the hand back is depressed, thus achieving thickening of the finger portions of the glove. FIG. 3 is a sectional view of FIG. 2 in A-A direction. As may be seen from FIG. 3, a first groove is formed on the palm back member, and the palm back portion of the glove may be thickened by the first groove. Further, the base is provided with a connecting hole, the connecting hole is a through hole or a threaded hole which helps fix the base to the base. Further, the steps for manufacturing the glove using the female die of the example are as follows. [0041] (1) The female die is cleaned and dried, then dipped in a coagulant and dried, the coagulant is an aqueous CaCl.sub.2) solution with a mass fraction of 3-20%. [0042] (2) The female die treated in step (1) is dipped with an emulsion, then set and dried. Typically but unrestrictedly, the dipping emulsion is mainly composed of a natural rubber latex, a compounding agent and a slurry containing a radiation protection material Bi.sub.2O.sub.3, and the compounding agent is mainly composed of a vulcanizing agent, a vulcanization accelerator, an antioxidant, a reinforcing agent and soft water. [0043] (3) The female die treated in step (2) is vulcanized, released and dried to obtain a finished glove product.

[0044] The thickness of the thickened portion of the glove manufactured in the example is 0.3-2.5 mm, and the thickness of unthickened portions is 0.1-0.3 mm.

Example 2

[0045] As shown in the figures, the female die comprises a base, an arm portion, a palm portion and finger portions. The base, the arm portion, the palm portion and the finger portions are connected in sequence as a whole. The arm portion and the palm portion are hollow structures. The finger portions comprise a thumb member, a forefinger member, a middle finger member, a ring finger member and a little finger member.

[0046] In the example, a first groove is formed on a palm back member. The thumb member and the forefinger member are provided with a second groove at one side of the palm back member respectively, and the second groove is connected with the first groove. The depth of the first groove and the second groove is 0.3-1.5 mm respectively. Different from example 1, in the example, only the thumb member and the forefinger member are provided with a second groove respectively. The area of the second groove on the thumb member and the forefinger member is 0.5 time that of the thumb member and the forefinger member at one side of the palm back member respectively. Surfaces of the first groove and the second groove are respectively provided with a hydrophilic coating with a thickness of 100-200 m.

[0047] In the example, the female die is made of stainless steel by investment casting, and the contact angle of the surface of the female die is 30-70. The hydrophilic coating is prepared from stainless steel by plasma spraying. The hydrophilic coating forms a porous water-absorbing surface with a contact angle of 2-30.

[0048] Further, the steps for manufacturing the glove using the female die of the example are as follows. [0049] (1) The female die is cleaned and dried, then dipped in a coagulant and dried, the coagulant is an aqueous CaCl.sub.2) solution with a mass fraction of 3-20%. [0050] (2) The female die treated in step (1) is dipped with an emulsion, then set and dried. Typically but unrestrictedly, the dipping emulsion is mainly composed of a carboxylic butadiene-acrylonitrite latex, a compounding agent and a slurry containing a radiation protection material WO.sub.3, and the compounding agent is mainly composed of a vulcanizing agent, a vulcanization accelerator, a reinforcing agent and soft water. [0051] (3) The female die treated in step (2) is vulcanized, released and dried to obtain a finished glove product.

[0052] The thickness of the thickened portion of the glove manufactured in the example is 0.3-2.5 mm, and the thickness of unthickened portions is 0.1-0.3 mm.

[0053] With convenient, simple and quick operation, the female die of the example may be used to manufacture a wall thickness-variable glove by one-time dipping. The manufactured wall thickness-variable glove may effectively protect doctors on the premise of ensuring flexible operation, and may particularly satisfy the requirement of protection against X-ray, and has good application prospects. The present invention is not limited to the embodiments, and expands to any new feature or any new combination disclosed in the specification, and steps in any new method or procedure or any new combination disclosed.
