Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1, the glove with high temperature resistance and particle splashing prevention disclosed in this embodiment includes a first knitted liner 1, the material adopted by the first knitted liner 1 is preferably flame-retardant non-melting fiber, and the flame-retardant non-melting fiber may be at least one of flame-retardant post-treatment fiber, flame-retardant acrylic fiber, fiber with polyamide group, pre-oxidized fiber and polybenzimidazole, or may be non-pure flame-retardant blended material.

The improvement of the embodiment is that at least one layer of outer sleeve layer 2 is sewed outside the first knitting inner container 1 through sewing threads. Of course, multiple layers are also possible, and the number of layers should not be limited here. The material of the outer jacket layer 2 may be selected from leather or thermoplastic elastomer, rubber or fabric. The materials can achieve the effect of high temperature resistance and difficult generation of molten liquid drops deep into the inner layer only through deformation.

Meanwhile, the gum dipping glue surface layer 3 is arranged on the palm surface, so that the flame retardant effect can be achieved, the glove thickness can be increased, the heat insulation effect is achieved, and the glue surface layer is a smooth surface and is not easy to cause knitting burning to generate molten drops. Only the palm surface is provided with the rubber surface layer, so that the other parts of the glove can ensure the air permeability, the softness and the comfort.

Referring to fig. 2, in this embodiment, a first air insulation layer 5 is left between the first knitted liner 1 and the outer jacket layer 2, and the air insulation layer plays a role in blocking heat and isolating radiation for the gloves.

The method of making the glove of this example is as follows:

the method comprises the following steps: weaving a first knitted liner 1 by adopting flame-retardant non-melting fibers;

step two: cutting the outer sleeve layer 2 by using leather or thermoplastic elastic materials;

step three: sewing the outer sleeve layer 2 with the back of the hand of the first knitted liner 1;

step four: and sleeving the semi-finished glove on a hand mold, dipping the palm part with glue, taking out and drying to obtain the finished glove.

The implementation principle of the embodiment is as follows: when an operator performs electric welding work, splashed sparks are sputtered on the back of the hand, the outer sleeve layer 2 can play the roles of resisting high temperature and preventing particles from splashing, and the gloves are thick and solid, so that the operator cannot easily feel heat. In addition, the inside gas permeability of gloves of this embodiment is good, and is soft, and operating personnel still feels comfortable after wearing for a long time, experiences and feels good.

Example two:

referring to fig. 3, the present embodiment is different from the first embodiment in that: at first knitting inner bag 1 internal connection has at least one deck inside lining 4, inside lining 4 for weaving integrative or polylith concatenation knitting fabric for the hand type, this knitting fabric is preferred with the knitting inner bag (being complete gloves) of the same structure of first knitting inner bag 1, or for cutting out integrative or polylith concatenation cutting out fabric for the hand type, inside lining 4 can adopt to sew up with the connected mode of first knitting inner bag 1, bonding etc. if adopt to sew up the connection, the preferred fire-retardant infusible fibre of sewing thread here. If a knitted liner is selected, the same first knitted liner 1 made of the same material can be used as the liner 4. But the knitting density can be slightly controlled. For example, the knitting density of the knitted liner as the inner lining 4 can be controlled to be 0.04g-0.1g per square centimeter gram weight, and the knitting density of the first knitted liner 1 as the outer layer can be controlled to be 0.05g-0.15g per square centimeter gram weight. The inner layer is light and thin, can guarantee air permeability, heat retention and travelling comfort, and after the intensive tissue of outside, can prevent that the melting liquid drop from permeating inside lining 4.

Referring to fig. 4, a second layer of air insulation 6 is typically left between the first knitted liner 1 and the inner liner 4. When the inner lining 4 is an integrated knitted liner, referring to fig. 5, a third air insulation layer 7 is also left in the knitted liner. Thus, double-layer air heat insulation is formed, and the high-temperature resistant effect can be improved.

The preparation method of the high-temperature-resistant and particle-splashing-preventing glove comprises the following steps:

the method comprises the following steps: weaving a first knitted liner 1 by adopting flame-retardant non-melting fibers;

step two: using a knitted liner integrated with weaving or a fabric liner integrated with cutting as a lining 4 layers;

step three: sewing the lining 4 layer with the back of the hand of the first knitted liner 1 through sewing threads;

step four: and turning over the semi-finished glove, sleeving the semi-finished glove on a hand mold, dipping the palm part with glue, taking out and drying to obtain the finished glove.

The implementation principle of the embodiment is as follows: when an operator performs electric welding work, splashed sparks are sputtered to the back of the hand, the multilayer gloves can play a role in heat insulation and high temperature resistance, and the flame-retardant non-melting fibers provide a flame-retardant self-extinguishing effect for the gloves. In addition, the gloves of this embodiment are inside gas permeability good, and are soft, and operating personnel still feels comfortable after wearing for a long time.

Example three:

the difference from the first embodiment is that: referring to fig. 6, a part of hollow fibers 8 are further woven into the first knitted liner 1, and a small metal fiber layer 9 is further hot-pressed on the outer surface of the gum dipping glue surface layer 3. The first knitted liner 1 ensures the comfort of the part of the glove directly contacting the skin, the hollow fiber 8 increases the strength of the glove, provides the heat preservation performance in winter, and can filter the toxic gas. The metal fibre layer 9, while providing flame-retardant and anti-melting properties, may also be used for particulate adsorption of the generated welding fumes, thereby reducing the risk of fumes to workers near the source.

The implementation principle of the embodiment is as follows: during the contact process of the welding rod and a weldment in the electric welding process, smoke dust is generated under the condition of high-temperature combustion, contains manganese dioxide, ozone and the like, and is harmful to a human body when floating in the air. The first contact place of the smoke is the gloves of workers, after the smoke is generated, the metal fiber layer 9 positioned on the outermost layer can absorb a part of particulate matters at the first time, and the hollow fiber 8 can absorb a part of harmful gas, so that the working safety of the workers is comprehensively improved.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
