Description

Technical Field

[0001] This application relates to the field of fabric technology, and in particular to a high tear-resistant and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fiber. Background Technology

[0002] Currently, the apparel market has increasingly higher requirements for the abrasion resistance and strength of fabrics. Traditional fabric materials have certain limitations in terms of abrasion resistance and strength.

[0003] Ultra-high molecular weight polyethylene fiber is currently the fiber with the highest specific strength and specific modulus in the world. It has many excellent properties such as ultra-high strength, ultra-high modulus, low density, wear resistance, low temperature resistance, ultraviolet resistance, anti-shielding, good flexibility, high impact energy absorption, and resistance to strong acids, strong alkalis, and chemical corrosion. It is widely used in military equipment, marine industry, safety protection, sports equipment and other fields.

[0004] Compared to ordinary polyethylene fibers, ultra-high molecular weight polyethylene (UHMWPE) fibers possess superior strength, toughness, impact resistance, cut resistance, abrasion resistance, and chemical corrosion resistance. Specifically, the specific strength of UHMWPE fibers is 15 times that of high-quality steel, 4 times that of glass and nylon 66, 2.6 times that of carbon fiber, and 1.7 times that of aramid fiber. In terms of impact resistance, the total energy absorbed by UHMWPE fiber composites is 1.8 times that of carbon fiber and 2.6 times that of aramid fiber.

[0005] Chinese patent application CN102797086A discloses a blended yarn of ultra-high molecular weight polyethylene (UHMWPE) fiber, which is made by blending UHMWPE fiber and other types of fibers through drawing and twisting; and the other types of fibers are any one or more combinations of polyester, nylon and pure cotton fibers, and all of them are long fibers.

[0006] However, this ultra-high molecular weight polyethylene fiber blended yarn is merely a simple combination of ultra-high molecular weight polyethylene limiter with other types of limiters. The functions and effects of the resulting blended yarn are difficult to achieve through technological breakthroughs, and the tear resistance and abrasion resistance of the obtained fabric are difficult to improve effectively. As a result, the increased cost far outweighs the improvement in performance, and it lacks practical market prospects and needs improvement. Summary of the Invention

[0007] In view of this, the purpose of this application is to provide a high-tear-resistance and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fibers, so as to achieve a significantly improved tear resistance and effective abrasion resistance. The specific solution is as follows:

[0008] A high tear-resistant and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fiber includes a body fabric woven from warp and weft yarns, wherein the warp yarns are nylon 66 and the weft yarns are nylon 66 and ultra-high molecular weight polyethylene fiber.

[0009] The main body fabric is impregnated with a hydrophobic slurry; the hydrophobic slurry consists of 80-100 parts by weight of trichloroacetyl isocyanate, 12-20 parts by weight of trifluoroethylene, and 10-12 parts by weight of [R1(R2)2SiO][(CH3)2SiO]. n [(CH3)2SiR3] and organic solvents, BDO, and dispersants as additives;

[0010] R1 and R3 are alkoxy or heterocyclic groups, respectively, and the heterocyclic group is selected from pyrrolidinyl, thiazolyl or indoleyl; R2 is a C1-C8 alkyl group.

[0011] Preferably, the ultra-high molecular weight polyethylene fiber is obtained by melt blending ultra-high molecular weight polyethylene, amino graphene, and nano-silica in a twin-screw extruder and then extruding; and the mass ratio of ultra-high molecular weight polyethylene, amino graphene, and nano-silica is 10-20:2-3:1-1.3; the temperature of the twin-screw extruder is controlled at 150-160℃ and the rotation speed is 120-140 r / min.

[0012] Preferably, the weft yarn is composed of nylon 66 and ultra-high molecular weight polyethylene fiber arranged in a 9:1 ratio, and the main body fabric is plain weave, with a warp density of 270-280 yarns / 10cm and a weft density of 160-170 yarns / 10cm.

[0013] Preferably, the organic solvent is diethyl ether, xylene, or isopropanol.

[0014] Preferably, the dispersant is polyethylene glycol, PEG-800, or PEG-1000.

[0015] Preferably, the main body fabric is desized, dyed and dried at low temperature after weaving, and then immersed in a hydrophobic sizing agent. After complete immersion, it is taken out and further dried at low temperature. The temperature of the low temperature drying treatment is controlled at 130°C and the dyeing temperature is below 115°C.

[0016] Preferably, the main body fabric is dried at a speed of 30m / min at low temperature, and overfed by 6%.

[0017] Preferably, the nylon 66 is a 320D / 136F CORDURA yarn.

[0018] As can be seen from the above solutions, this application provides a high tear-resistant and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fibers, which has the following beneficial effects:

[0019] 1. By using nylon 66 as the warp and nylon 66 and ultra-high molecular weight polyethylene fiber as the weft, a plain weave fabric is obtained. This fabric is then impregnated with a mixture of trichloroacetyl isocyanate, trifluoroethylene, and [R1(R2)2SiO][(CH3)2SiO]. n A hydrophobic slurry composed of [(CH3)2SiR3] and organic solvents, BDO, and dispersants as additives will, while giving the main fabric a hydrophobic function, utilize trifluoroethylene, [R1(R2)2SiO][(CH3)2SiO] to achieve the same effect. n The combination of [(CH3)2SiR3] and trichloroacetyl isocyanate adheres to the main fabric, thereby further enhancing the fabric structure strength of the high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber in a low-temperature drying process, thus achieving a significant improvement in the tear resistance and abrasion resistance of the high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber, and has broad industrial production value.

[0020] 2. By interlacing the warp and weft yarns in a plain weave structure, the number of interlacing steps is increased and the float length is shortened, which significantly improves the fabric's strength and abrasion resistance, and effectively prevents pilling and improves its anti-snagging properties.

[0021] 3. By controlling the low-temperature drying temperature and the dyeing temperature, effective dyeing of nylon 66 can be achieved while avoiding affecting the limiting strength of ultra-high molecular weight polyethylene fiber, thereby enabling the main fabric to achieve effective structural stability and abrasion resistance.

[0022] 4. By impregnating the main fabric with a hydrophobic slurry to significantly improve its hydrophobic properties, the structural strength of the high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber is further improved, thereby achieving a significant improvement in the tear resistance and abrasion resistance of the high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber.

[0026] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] It should be mentioned that the following will specifically describe the high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber of this application.

[0028] like Figure 1 As shown, a high tear-resistant and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fiber includes a body fabric woven from warp and weft yarns.

[0029] in:

[0030] The main body fabric has a plain weave structure with a warp density of 65-75 yarns / 10cm and a weft density of 38-42 yarns / 10cm. Therefore, through the plain weave structure of the warp and weft yarns, this main body fabric significantly improves durability and abrasion resistance while effectively preventing pilling and enhancing snag resistance, thus increasing the number of interlacing operations and shortening float lengths.

[0031] The warp yarn is nylon 66.

[0032] The weft yarns are made of nylon 66 and ultra-high molecular weight polyethylene fibers. Meanwhile, the weft yarns are composed of nylon 66 and ultra-high molecular weight polyethylene fibers arranged in a 9:1 ratio.

[0033] Specifically, nylon 66 is a 320D / 136F CORDURA yarn.

[0034] It should be noted that ultra-high molecular weight polyethylene (UHMWPE) fiber is obtained by melt blending and extruding UHMWPE, amino graphene, and nano-silica using a twin-screw extruder, with the mass ratio of UHMWPE, amino graphene, and nano-silica being 10-20:2-3:1-1.3. During the production process of UHMWPE fiber, the twin-screw extruder is controlled at a temperature of 150-160℃ and a rotation speed of 120-140 r / min to obtain the appropriate fiber.

[0035] It should be mentioned that, in order to further enhance the structural strength of this high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber and thus improve its tear resistance and abrasion resistance, the main fabric is subjected to further hydrophobic slurry impregnation treatment.

[0036] The hydrophobic slurry consists of 80-100 parts by weight of trichloroacetyl isocyanate, 12-20 parts of trifluoroethylene, and 10-12 parts of [R1(R2)2SiO][(CH3)2SiO]. n [(CH3)2SiR3] consists of an organic solvent, BDO, and a dispersant as additives.

[0037] Therefore, this high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber significantly improves its hydrophobic properties by impregnating the main fabric with a hydrophobic slurry, while further enhancing the structural strength of the fabric, thereby achieving a significant improvement in the tear resistance and abrasion resistance of the fabric containing ultra-high molecular weight polyethylene fiber.

[0038] The amount of additives added is not limited by weight. The weight of BDO and dispersant is determined by the organic solvent, which will not be elaborated here.

[0039] For specific details, the following are included:

[0040] R1 and R3 are alkoxy or heterocyclic groups, respectively, and the heterocyclic group is selected from pyrrolidinyl, thiazolyl or indoleyl.

[0041] R2 is a C1-C8 alkyl group.

[0042] In the hydrophobic slurry of the ultra-high molecular weight polyethylene fiber high tear and abrasion resistant fabric of this application, diethyl ether, xylene or isopropanol is used as organic solvent, and if the organic solvent is ethylene glycol, BDO is not added.

[0043] In addition, the dispersant is polyethylene glycol, PEG-800 or PEG-1000, and accounts for 1-5% of the mass of the hydrophobic slurry.

[0044] Meanwhile, the preparation process of this high-tear-resistance and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fiber is as follows: First, a base fabric is obtained, which is then woven and subsequently desized, dyed, and dried at low temperature. Next, the low-temperature dried base fabric is immersed in a hydrophobic sizing agent, and after complete immersion, it is removed and further dried at low temperature. This low-temperature drying process controls the temperature to 130℃, the dyeing temperature to below 115℃, and the drying speed to 30m / min with a 6% overfeed. This ensures effective dyeing of nylon 66 while avoiding affecting the limiting strength of the ultra-high molecular weight polyethylene fiber, thereby achieving effective structural stability and abrasion resistance in the base fabric.

Therefore, through the plain weave structure of the warp and weft yarns, the main body fabric significantly improves its strength and abrasion resistance while effectively preventing pilling and enhancing its anti-snagging properties, thereby increasing the number of interlacing layers and shortening the float length.

[0049] The warp yarn is nylon 66.

[0050] The weft yarns are made of nylon 66 and ultra-high molecular weight polyethylene fibers. Meanwhile, the weft yarns are composed of nylon 66 and ultra-high molecular weight polyethylene fibers arranged in a 9:1 ratio.

During the production process of UHMWPE fiber, the twin-screw extruder is controlled at a temperature of 150℃ and a rotation speed of 120 r / min to obtain the desired fiber.

[0053] It should be mentioned that, in order to further enhance the structural strength of this high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber and thus improve its tear resistance and abrasion resistance, the main fabric is subjected to further hydrophobic slurry impregnation treatment.

[0054] The hydrophobic slurry consists of 80 parts by weight of trichloroacetyl isocyanate, 12 parts by weight of trifluoroethylene, and 10 parts by weight of [R1(R2)2SiO][(CH3)2SiO]. n [(CH3)2SiR3] consists of an organic solvent, BDO, and a dispersant as additives.

[0055] Therefore, this high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber significantly improves its hydrophobic properties by impregnating the main fabric with a hydrophobic slurry, while further enhancing the structural strength of the fabric, thereby achieving a significant improvement in the tear resistance and abrasion resistance of the fabric containing ultra-high molecular weight polyethylene fiber.

[0059] R2 is a C1 alkyl group.

[0060] Meanwhile, the preparation process of this high-tear-resistance and abrasion-resistant fabric containing ultra-high molecular weight polyethylene fiber is as follows: First, a base fabric is obtained, which is then woven and subsequently desized, dyed, and dried at low temperature. Next, the low-temperature dried base fabric is immersed in a hydrophobic sizing agent, and after complete immersion, it is removed and further dried at low temperature. This low-temperature drying process controls the temperature to 130℃, the dyeing temperature to below 115℃, and the drying speed to 30m / min with a 6% overfeed. This ensures effective dyeing of nylon 66 while avoiding affecting the limiting strength of the ultra-high molecular weight polyethylene fiber, thereby achieving effective structural stability and abrasion resistance in the base fabric.

During the production process of UHMWPE fiber, the twin-screw extruder is controlled at a temperature of 155℃ and a rotation speed of 130 r / min to obtain the appropriate fiber.

[0069] It should be mentioned that, in order to further enhance the structural strength of this high tear and abrasion resistant fabric containing ultra-high molecular weight polyethylene fiber and thus improve its tear resistance and abrasion resistance, the main fabric is subjected to further hydrophobic slurry impregnation treatment.
