In order to more clearly describe the technical content of the present invention, the following further description is given with reference to specific embodiments.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 4, in this embodiment, the protective fire-fighting glove of the present invention includes a knitted layer structure 1 located at the outermost layer of the glove and located at the back of the hand. The position in which the knitted layer structure 1 is specifically provided in this embodiment can be seen in fig. 1, where the gray zone block position in fig. 1 is the position in which the knitted layer structure 1 is provided. The dashed lines in the figure represent actual suture positions, i.e. the dashed lines represent open lines. It can be seen from the figure that the knitted layer structure 1 extends from the wrist position of the back of the hand up to the finger joints of the near-finger tip portions of the index finger, middle finger, ring finger and little finger.

As shown in fig. 2, in this embodiment, the knitted layer structure 1 includes a first aramid knitted layer 11 and a flame-retardant film layer 12, the first aramid knitted layer 11 is located at the outermost layer of the glove, and the flame-retardant film layer 12 is located at the inner side surface of the first aramid knitted layer 11.

The outermost layer of the glove is made of aramid fiber cloth, so that flame retardance can be effectively realized, and the aramid fiber cloth with a knitted structure has better elasticity than the aramid fiber cloth with a woven structure, so that the glove can achieve the flame retardance effect and increase the flexibility of the glove. Meanwhile, the flame retardant performance can be effectively improved by adding the flame retardant film layer 12, meanwhile, in the embodiment, the flame retardant film layer 12 is formed by adopting a polytetrafluoroethylene film (namely, a PTFE film) which has the characteristic of water resistance, so that water or other solutions can be effectively prevented from entering the interior of the glove during fire-fighting and rescue, the fire-fighting comfort of a fireman is improved, and the knitted layer structure 1 can ensure that the glove has good cut-proof and cut-proof characteristics, so that the hand of the fireman can be better protected, preferably, the polytetrafluoroethylene film is an expanded polytetrafluoroethylene film (namely, the flame retardant film layer is formed by an ePTFE film, wherein ePTFE is an abbreviation of expanded PTFE and is a product processed into a porous structure by using a PTFE resin raw material).

In this embodiment, the first aramid fiber knitting layer 11 has a structure in which the aramid fiber yarns 111 are bent in the transverse direction to form loops and are interlooped with each other, in this embodiment, the first aramid fiber knitting layer 11 is a double-faced aramid fiber woven fabric, and the structure thereof can be seen from fig. 3, and it can be seen that the first aramid fiber knitting layer 11 in this embodiment is a weft-knitted fabric (i.e., it is an Interlock knitted fabric structure) having a double rib structure made of the aramid fiber yarns 111, and the aramid fiber yarns 111 are bent in the transverse direction to form loops and are interlooped with each other.

In this embodiment, the first aramid fiber knitted layer 11 is formed by a double-sided aramid fiber knitted fabric formed by co-weaving m-aramid fiber yarns and p-aramid fiber yarns.

In this embodiment, the meta-aramid yarn is located on the outer side of the double-sided aramid knitted fabric, and the para-aramid yarn is located on the inner side of the double-sided aramid knitted fabric.

In this embodiment, the knitting layer structure 1 further includes a second aramid fiber knitting layer 13, and the flame retardant film layer 12 is located between the first aramid fiber knitting layer 11 and the second aramid fiber knitting layer 13. In this embodiment, the flame-retardant film layer 12 is bonded between the aramid fiber knitted layer 11 and the second aramid fiber knitted layer 13, that is, the first aramid fiber knitted layer 11, the flame-retardant film layer 12 and the second aramid fiber knitted layer 13 are tightly adhered to each other, so that when the glove is used, relative displacement between the structures in the knitted layer structure 1 does not occur, the relative position is fixed, and the cutting resistance, the puncture resistance, the heat resistance and other properties of the back of the hand of the fire-fighting glove are further improved. When the gloves are manufactured, the shapes of the first aramid fiber knitting layer 11, the flame-retardant film layer 12 and the second aramid fiber knitting layer 13 are matched with each other.

In this embodiment, the second aramid knitted layer 13 is made of a para-aramid knitted fabric. Through increasing this second aramid fiber knitting layer 13 can further improve heat-resisting, resistant puncture, anti cutting and resistant tear performance, simultaneously, the setting of second aramid fiber knitting layer 13 also can produce certain protectiveness to fire-retardant rete 12, effectively prolongs the life of gloves.

In this embodiment, the glove further comprises a flame-retardant layer structure 2 disposed at the palm position, and the flame-retardant layer structure 2 and the knitted layer structure 1 are sewn together to form an outer layer of the glove.

In this example, the flame-retardant layer structure 2 is made of flame-retardant kraft.

In the embodiment, as can be seen from fig. 1 and fig. 4, only the back of the hand is provided with the knitted layer structure 1 (namely, the wrist part of the front side of the glove extends to the part of four fingers other than the thumb all by the knitted layer structure 1), and the side surfaces of the palm and the hand are both provided with the flame-retardant layer structure 2, because the knitted layer structure 1 has the characteristic of good elasticity, the glove can well take account of the flame-retardant performance and the use flexibility, the wearing performance of the glove is improved, the bending movement of the fingers is more convenient, and the hand is effectively protected. Meanwhile, as shown in fig. 1, the center of the back of the hand of the glove is also provided with a reflective strip 3, the center of the palm of the hand of the glove is also provided with a reinforcing layer 4, and the reinforcing layer 4 for further protecting the palm of the hand can also be made of flame-retardant cowhide. Meanwhile, the glove opening is provided with a rib opening 5, so that the glove is higher in fitting degree and not easy to fall off when being provided with the glove.

In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
