Description

Technical Field

[0001] The invention relates to the technical field of coated fabrics, in particular to a polymer coated mixed woven fabric and a preparation method thereof. Background Art

[0002] At present, polymer-coated polyester, nylon and other reactive surface fiber fabrics are widely used in the field of industry and protective materials because of their low cost and strong durability. However, their mechanical properties such as tensile, tearing and puncture resistance are poor, and it is difficult to meet high performance requirements. Ultra-high molecular weight polyethylene (UHMWPE) and other inert surface fibers have gradually become the preferred materials for composite materials due to their excellent mechanical properties, but the insufficient bonding strength between them and conventional TPU or PVC polymer coatings limits their application in the field of coated fabrics. Invention patent CN201610004369.9 discloses a new type of ultra-high molecular weight polyethylene braided fire hose and a manufacturing method thereof, which uses ultra-high molecular weight polyethylene filament warp and ultra-high molecular weight polyethylene pure spun staple yarn weft to prepare a tubular fabric by knitting, and coats the surface with modified polyurethane, but does not mention the key indicator of coating bonding strength. In addition, the prior art improves the interfacial bonding performance of inert surface fibers with polymer matrices by plasma treatment, chemical etching and other methods, but the equipment cost is high and the processing efficiency is low. Therefore, developing a polymer-coated fabric with higher coating adhesion strength and better comprehensive mechanical properties through process improvement has become an urgent problem to be solved. Summary of the invention

[0003] The object of the present invention is to provide a polymer coated hybrid fabric and a preparation method thereof. The prepared polymer coated hybrid fabric has higher coating adhesion strength, excellent comprehensive mechanical properties and simple preparation process.

[0004] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions: The present invention provides a method for preparing a polymer coated hybrid fabric, comprising the following steps: Mixing and weaving fiber filament yarns with inert surfaces and fiber filament yarns with reactive surfaces to obtain a mixed knitted fabric; The mixed braided fabric is subjected to corona treatment to obtain a treated mixed braided fabric; The treated mixed woven fabric is dipped in glue, and then allowed to stand for defoaming to obtain a dipped fabric; After the dipped fabric is treated with glue, it is cast and compounded with a polymer matrix to obtain a polymer-coated mixed woven fabric; The fiber with inert surface in the fiber filament yarn with inert surface includes one or more of aramid fiber, ultra-high molecular weight polyethylene fiber, carbon fiber, polybenzimidazole fiber, polyimide fiber, polyetheretherketone fiber and polyhydrazide fiber; The reactive surface fibers in the reactive surface fiber filament yarn include one or more of polyester and nylon fibers; The mixed conditions include: the warp density is 15-30 yarns / inch; the weft density is 15-30 yarns / inch; the warp arrangement ratio of the fiber filament yarn with an inert surface to the fiber filament yarn with a reactive surface is 1-2:1; the weft arrangement ratio of the fiber filament yarn with an inert surface to the fiber filament yarn with a reactive surface is 1:1-2; the twist of the fiber filament yarn with an inert surface is 50-100 twists / meter; the twist of the fiber filament yarn with a reactive surface is 0-10 twists / meter.

[0005] Preferably, the fineness of the fiber filament yarn with an inert surface is 500-1500D; the fineness of the fiber filament yarn with a reactive surface is 1000-2000D.

[0006] Preferably, the mixed weave is plain weave or twill weave.

[0007] Preferably, the conditions of the corona treatment include: power of 50-150 W·min / m 2 , processing speed is 3~6m / min, and electrode voltage is 10~20kV.

[0008] Preferably, the conditions for the dipping treatment include: the viscosity of the glue solution is 150-300 mPa·s, the coating amount of the glue solution is 30-50 g / m 2 ; The drying temperature after the dipping process is completed is 135~155℃.

[0009] Preferably, the standing defoaming time is 40 to 60 minutes.

[0010] Preferably, the conditions for the glue coating process include: the viscosity of the scraping glue solution is 15000-25000 mPa·s; two scraping passes are used on each side of the fabric, and the amount of glue applied in the first scraping pass is 45-55 g / m 2 The second coating amount is 25~35g / m 2 ; The drying temperature after the gluing process is completed is 135~155℃.

[0011] Preferably, the glue used in the dipping process and the coating process is independently a mixture of a polyurethane resin adhesive and a curing agent.

[0012] Preferably, the polymer matrix comprises TPU or PVC.

[0013] The present invention provides a polymer coated mixed braided fabric prepared by the preparation method described in the above technical solution.

[0014] The present invention provides a preparation method of a polymer-coated mixed fabric, which improves the bonding strength between the fabric and the polymer coating by optimizing the surface structure of the fabric, the fiber arrangement, and the differentiated setting of the yarn twist, thereby solving the problem of insufficient bonding strength between the fiber with an inert surface and the surface of the polymer matrix (TPU or PVC). Through the differentiated design of the warp and weft density, the mesh size of the interweaving points on the fabric surface is increased, and the penetration and coating effect of the glue solution is improved. Through the differentiated design of the yarn fineness and twist of the fiber with an inert surface and the fiber with a reactive surface, the area proportion of the fiber with a reactive surface on the fabric surface is increased, and the coating bonding strength advantages of the fiber with a reactive surface and the mechanical property advantages of the fiber with an inert surface are brought into play. At the same time, it is limited that the proportion of the fiber with a reactive surface in the weft direction of the mixed fabric is greater than the proportion of the fiber with a reactive surface in the warp direction, and by reducing the proportion of the fiber with an inert surface in the weft yarn, the shrinkage of the fabric is reduced during the process of dipping, coating, drying, and compounding, and the influence of the shrinkage of the fiber with an inert surface at high temperature on the width of the fabric is reduced.

[0015] In addition, the present invention adds inert surface fibers to the fabric, while maintaining high tensile, tear and puncture resistance, achieving good flexibility and processability. Conventional polymer coated fabrics usually use reactive surface fiber fabrics as the middle layer, but the fabric tensile, tear and puncture resistance are relatively poor. The negative effect of adding inert surface fibers is the decrease in coating adhesion strength, because the surface of the inert surface fibers is smooth and it is difficult to form a strong interface bond with the glue. Therefore, the present invention uses a mixed weaving method to make the fabric have both reactive surface fibers and inert surface fibers, and increase the exposure ratio of reactive surface fibers on the fabric surface, and reduce the exposure ratio of inert surface fibers on the fabric surface, so as to minimize the reduction in coating adhesion strength caused by the presence of inert surface fibers.

[0016] The invention improves the coating bonding strength of the polymer-coated mixed woven fabric by optimizing the fabric structure design and the surface treatment process, has a simple preparation method, and is suitable for large-scale industrial production.

[0017] The present invention optimizes the surface treatment process by combining multiple methods such as corona + dipping + coating, achieves better coating adhesion strength, and increases the interface bonding between fabric and glue from multiple angles. Among them, the corona treatment introduces polar functional groups on the surface of the fabric, especially on the surface of the fiber with inert surface, through high-voltage discharge, increases the surface energy, and enables the coating material to spread and adhere better. The dipping treatment uses a low-viscosity glue to allow the glue to penetrate into the interior of the fabric, and after drying, a base glue coating layer is formed inside and on the surface of the filament yarn inside the fabric. The use of a low-viscosity glue for dipping can reduce the volatilization of organic solvents inside the fabric during the drying process to generate bubbles and thus affect the coating adhesion strength. The coating treatment uses a high-viscosity glue to be applied to the surface of the fabric after dipping to form a glue layer, so that the fabric maintains a high glue application amount, which is convenient for subsequent casting and compounding with TPU.

[0045] Comparative Example 1 The difference from Example 1 is that no dipping treatment is performed, and only the mixed woven fabric in step 2) is coated with glue and then cast and composited.

[0046] Comparative Example 2 The difference from Example 1 is that the scraping is performed in one stroke.

[0047] Comparative Example 3 The difference from Example 1 is that the drying temperature after dipping and coating is set to 160°C.

[0048] Comparative Example 4 The difference from Example 1 is that the warp yarn density and the weft yarn density are both set to 22 yarns / inch.

[0049] Comparative Example 5 The difference from Example 1 is that neither the warp yarn nor the weft yarn is twisted.

[0050] Comparative Example 6 The difference from Example 1 is that in step 1), the fabric is woven with pure polyester, the fineness of the polyester filament yarn is 1500D, the warp density is 20 yarns / inch, the weft density is 18 yarns / inch, the polyester twist is 0 twist / m, and no mixing is performed.

[0052] Performance Testing The performance of the blended fabrics prepared in Example 1 and Comparative Examples 1 to 7 was tested by using methods such as HG T 3052-2008 Determination of adhesion strength of coating layer of rubber or plastic coated fabrics (peeling strength generated by peeling TPU off the blended fabric after glue coating), HG_T 2580-2022 Determination of tensile strength and elongation at break of rubber or plastic coated fabrics, HG_T 2581.1-2009 Determination of tear resistance of rubber or plastic coated fabrics Part 1 - Constant rate tearing method, and GB_T 31064-2014 Test method for puncture resistance of rubber or plastic coated fabrics. The results are shown in Table 1.

[0053] Table 1 Test results of the mixed fabrics in Example 1 and Comparative Examples 1 to 7 serial number Peel strength (N / 25mm) Warp tensile strength (N / 50mm) Weft tensile strength (N / 50mm) Warp tear strength (N / 50mm) Weft tear strength (N / 50mm) Puncture resistance (N) Example 1 74 10161 7296 1929 1797 1149 Comparative Example 1 56 10098 7183 1901 1731 1109 Comparative Example 2 52 10045 7154 1867 1728 1097 Comparative Example 3 65 7540 5479 1287 1355 1124 Comparative Example 4 54 10743 10637 1988 1980 1551 Comparative Example 5 50 10104 7266 1919 1765 1156 Comparative Example 6 98 4203 3834 729 597 687 Comparative Example 7 35 11460 10364 1845 1833 1979 As shown in Table 1, the polymer coated blended fabric obtained in Example 1 has better comprehensive performance; the difference between Comparative Example 1 and Example 1 is that no dipping treatment is performed, and only high-viscosity glue is used for scraping in the glue coating, and the glue is difficult to penetrate into the yarn, which is not conducive to the improvement of the coating adhesion strength; the difference between Comparative Example 2 and Example 1 is that one scraping is used, and since the thickness of the single scraping glue coating is large, the volatile solvent in the glue is difficult to be fully removed, resulting in more bubbles in the glue layer, which has a negative impact on the coating adhesion strength. The difference between Comparative Example 3 and Example 1 is that the drying temperature during the dipping and scraping process is set to 160°C. Since the blended fabric contains ultra-high molecular weight polyethylene, the excessive processing temperature exceeds its glass transition temperature, resulting in thermal damage to the fiber, decreased mechanical properties, and severe shrinkage. The difference between Comparative Example 4 and Example 1 is that the warp and weft yarn densities are both set to 22 strands / inch, and the warp and weft yarn densities are set too high, resulting in the fabric being too tight, which is not conducive to the infiltration of the glue. The difference between Comparative Example 5 and Example 1 is that the warp and weft yarns are not twisted, and the ultra-high molecular weight polyethylene is not twisted. Its proportion on the fabric surface is equivalent to that of polyester. The coating adhesion strength advantage of polyester is difficult to be fully utilized, and the coating adhesion strength is still insufficient. The difference between Comparative Example 6 and Example 1 is that the fabric is woven with pure polyester. Although the coating adhesion strength is very high, other mechanical properties are seriously insufficient. The difference between Comparative Example 7 and Example 1 is that the fabric is woven with pure ultra-high molecular weight polyethylene. Although the tensile, tearing and puncture resistance properties are better, the coating adhesion strength is seriously insufficient.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
