Description

Technical Field

[0001] This utility model relates to the field of textile protective clothing technology, and more specifically, to a welded garment fabric with a variable weft-weight flat structure. Background Technology

[0002] The sparks and arc light produced during welding can cause harm to the human body. Therefore, appropriate personal protective equipment (PPE) must be worn when performing welding operations, including protective masks, protective clothing, and protective gloves. The protective effect of PPE largely depends on the performance of welding protective fabrics. Currently, welding protective materials with good heat insulation and thermal stability are not comfortable, while welding protective materials with good comfort have poor heat insulation and thermal stability.

[0003] Existing technical solutions mostly improve the fabric by using high-performance fibers or yarns and by applying finishing coatings. However, relying on high-performance fibers results in high material costs, makes market promotion difficult, and struggles to achieve comprehensive performance. For example, Chinese utility model patent CN218521390U discloses a three-dimensional air tube structure welded garment fabric. This primarily uses elastic yarns to create a raised weft yarn, forming a semi-circular air cavity between the radial and weft yarns. This structure allows the fabric to store a certain amount of air, increasing its overall thermal insulation and heat protection performance. However, optimizing the fabric from a planar structure to a three-dimensional structure through the elastic recovery force of the weft yarns can easily lead to poor thermal stability. Furthermore, fabrics relying on finishing coatings to achieve thermal stability still suffer from poor durability and are heavy. Utility Model Content

[0004] The purpose of this invention is to address the problems in the prior art by providing a variable weft-weight flat structure welding garment fabric. By equipping the outer and inner layers of the fabric with yarns of different functions, different protective functions are achieved, solving the problem of poor overall thermal performance of comfortable welding protective clothing, and also providing resistance to molten metal impact.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a variable weft-weight flat structure welded garment fabric, the fabric comprising several layers of warp and weft yarns interwoven in a triple weft structure, each layer of the triple weft structure having a surface structure, an intermediate structure, and a reverse structure:

[0007] The weft yarn includes surface weft yarn, middle surface weft yarn, and reverse weft yarn;

[0013] Optionally, both the second warp yarn and the reverse weft yarn are blended yarns made of aramid 1313 fiber and polyimide fiber.

[0014] Optionally, the intermediate weft yarn is aramid fiber yarn.

[0015] Optionally, the surface texture is a satin surface texture, the reverse texture is a satin reverse texture, and the middle texture is a twill middle texture.

[0016] Optionally, four second warp yarns are arranged between two adjacent first warp yarns;

[0017] The two first warp yarns are respectively arranged on opposite sides of the surface weft yarn and the reverse weft yarn;

[0018] The four second warp yarns are arranged in pairs, with one pair of second warp yarns threaded between the opposite faces of the surface weft yarn and the middle weft yarn, and the remaining pair of second warp yarns threaded between the opposite faces of the reverse weft yarn and the middle weft yarn.

[0025] The beneficial effects of this utility model include:

[0026] 1) This utility model achieves different protective functions by equipping the surface, middle, and reverse sides of the fabric structure with yarns of different functions. The surface yarn has the characteristics of high slippage and high moisture absorption, which can quickly slip off the molten metal droplets when impacted by molten metal, preventing the high-temperature droplets from damaging the skin. The middle yarn has good thermal stability and mainly plays the role of preventing shrinkage when heated in the fabric. The reverse yarn has high strength, forming a stable and three-dimensional fabric structure. The resulting fabric has flame retardancy, thermal stability, abrasion resistance, and heat radiation resistance. While maintaining the comfort of the fabric, it improves the thermal structural stability of the fabric, thereby effectively improving the radiative heat performance, thermal stability, and thermal protection performance of the fabric.

[0027] 2) This utility model uses a specific variation of the weft-weight flat weave structure to cover the middle and reverse sides of the fabric with colored functional yarns that have poor colorability, while the dyeable yarns are exposed on the surface of the fabric. This allows the fabric to be printed with more colors while maintaining its functionality, thereby increasing its market applicability. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. It should be noted that, without conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0034] The sparks and arc light generated during welding can cause harm to the human body. Therefore, appropriate personal protective equipment (PPE) must be worn during welding operations, including protective masks, protective clothing, and protective gloves. The protective effect of personal welding protective equipment largely depends on the performance of the welding protective fabric. Therefore, a welding protective fabric with good protective performance should first be flame-retardant, and to avoid burns, it should also have good resistance to impact from molten metal. In addition, it should have good heat insulation and thermal stability to avoid or reduce damage caused by high heat source temperatures. In existing solutions, products with good heat insulation and thermal stability have poor comfort, while products with good comfort have poor heat insulation and thermal stability. Therefore, this application provides a welding clothing fabric with a variable weft-weight plain structure to solve the problem of poor overall thermal performance of comfortable welding protective clothing.

[0035] This application provides a variable weft-weight flat-structure welded garment fabric, such as... Figure 1 , Figure 2 and Figure 3 As shown, the fabric comprises several layers of warp and weft yarns interwoven in a triple-weft structure. Each layer of the triple-weft structure has a surface structure, an intermediate structure, and a reverse structure: the weft yarns include a surface weft yarn W1, an intermediate weft yarn W2, and a reverse weft yarn W3; the surface weft yarn W1 interweaves with the warp yarns to form the surface structure; the intermediate weft yarn W2 interweaves with the warp yarns to form the intermediate structure; and the reverse weft yarn W3 interweaves with the warp yarns to form the reverse structure. These warp and weft yarns are woven on a loom to form a specific variable-weight plain weft structure fabric.

[0036] Specifically, the warp includes a first warp T1 and a second warp T2, which are arranged in a repeating pattern on the same reference plane at a ratio of 1:2-4.

[0037] like Figure 3As shown, in one embodiment of this application, four second warp yarns T2 are arranged between two adjacent first warp yarns T1; the two first warp yarns T1 are respectively arranged on opposite sides of the surface weft yarn W1 and the reverse weft yarn W3; the four second warp yarns T2 are arranged in pairs, one pair of second warp yarns T2 is threaded between the opposite sides of the surface weft yarn W1 and the middle weft yarn W2, and the remaining pair of second warp yarns T2 is threaded between the opposite sides of the reverse weft yarn W3 and the middle weft yarn W2.

[0038] Specifically, the first warp yarn T1 and the surface weft yarn W1 are both blended yarns of flame-retardant viscose fiber and nylon 6 fiber; the second warp yarn T2 and the reverse weft yarn W3 are both blended yarns of aramid 1313 fiber and polyimide fiber; and the middle weft yarn W2 is aramid fiber.

[0039] Specifically, in the blended yarns that make up the slip-off functional weft and warp yarns, the proportion of flame-retardant viscose fiber is greater than 80% and less than 90%, and the proportion of nylon 6 fiber is greater than 10% and less than 20%; in the aramid fiber yarns that make up the mechanical functional weft yarns, the proportion of aramid 1313 fiber is greater than 90% and less than 95%, and the proportion of aramid 1414 fiber is greater than 5% and less than 10%; in the blended yarns that make up the thermal functional weft and warp yarns, the proportion of aramid 1313 fiber is greater than 70% and less than 80%, and the proportion of polyimide fiber is greater than 20% and less than 30%.

[0040] Specifically, the surface weave is satin surface weave 10, the reverse weave is satin reverse weave 20, and the middle weave is twill middle weave 30. Preferably, the surface weave is an 8 / 5 weft satin weave, the reverse weave is a reverse 8 / 5 weft satin weave, and the middle weave is a 2 / 2 right twill weave.

[0041] Specifically, the weft yarn count is 13.1 tex × 2 (50 S / 2), using a compact spinning process, with an S-twist direction; the warp yarn count is 10.74tex×2(50 S / 2), using a compact spinning process, with an S-twist.

[0042] Specifically, the warp density of variable weft plain weave fabric is 65-70 threads / inch; the weft density is 145-150 threads / inch.

[0043] Specifically, the unit area mass of the variable weft-weight plain structure fabric is 230g / ㎡-240g / ㎡.

[0044] This application's embodiments, based on the principle of triple weft weave, vary the structure and yarn combinations to form a variable weft-weight plain weave welded garment fabric, such as... Figure 1As shown, the fabric includes a surface, a middle surface, and a reverse surface. Both the surface and reverse surface are weft-faced satin weaves, while the middle surface is twill. The surface exhibits high slip resistance, moisture absorption, and flame retardancy; the middle surface possesses high strength, high thermal stability, and flame retardancy; and the reverse surface exhibits high thermal stability, high slip resistance, and flame retardancy. The fabric's structure consists of two warp yarns and three weft yarns, with the surface, middle surface, and reverse surface all composed of interwoven warp and weft yarns. Through specific variations in weft-weight flat structure and specific combinations of functional yarns, a welding protective clothing fabric with excellent thermal properties is formed. This application's embodiment starts with the design of the fabric's structure, combining the functionality of various yarns to design a welding protective fabric with excellent thermal properties. Without reducing the comfort of the welding fabric, it improves the heat insulation, thermal stability, abrasion resistance, and heat radiation resistance of the welding fabric, solving the problem of insufficient thermal performance in existing welding clothing fabrics.

[0045] This application embodiment achieves different protective functions by equipping the surface, middle, and reverse sides of the fabric structure with yarns of different functions. The surface yarn has the characteristics of high slippage and high moisture absorption, which can quickly slip off molten metal droplets when impacted, preventing high-temperature droplets from damaging the skin. The middle yarn has good thermal stability and mainly plays the role of preventing shrinkage when heated in the fabric. The reverse yarn has high strength, forming a stable and three-dimensional fabric structure. The resulting fabric has flame retardancy, thermal stability, abrasion resistance, and heat radiation resistance. While maintaining the comfort of the welding fabric, it improves the thermal structural stability of the welding fabric, thereby effectively improving the radiative heat performance, thermal stability, and thermal protection performance of the fabric. This utility model uses a specific variation of the weft-weight plain weave structure to cover the middle and reverse sides with colored functional yarns that have poor colorability, while the dyeable yarns are exposed on the surface. This allows the fabric to be printed with more colors on the basis of its overall functionality, thereby increasing its market applicability.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
