Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically relating to a high-strength tear-resistant fabric. Background Technology

[0002] As a product line of textiles, webbing has long been used as a fastening and / or sling for securing, binding, or lifting various types of objects. When such fastenings and / or slings are used in certain scenarios, such as animal bite restraint webbing or outdoor climbing safety webbing, their outer surface often comes into contact with animal teeth or sharp rocks. When these teeth or sharp rocks move or cut into the outer surface of the webbing, they can cause wear and tear, and in severe cases, even tearing or ripping the webbing. This can allow animals to escape from the restraints or climbers to fall, thereby endangering public safety.

[0003] To address the issue of existing webbing being easily worn, torn, or snapped by sharp objects, a single high-strength polyethylene fiber (e.g., Polyethylene fiber) or aramid fiber (e.g.) While webbing made from a single high-strength polyethylene fiber or aramid fiber can exceed expectations in meeting practical needs, its relatively high price leads to higher production costs, which is disadvantageous. On the other hand, to reduce production costs, it is easy to consider blending high-strength polyethylene fiber or aramid fiber with other lower-priced fibers. However, the variety of lower-priced fibers used for blending and the difficulty in determining the blending ratio often result in the blended webbing's abrasion resistance, tear resistance, and bite resistance not meeting expectations.

[0004] In view of the above-mentioned defects, it is necessary to provide a high-strength tear-resistant fabric with lower production cost. Summary of the Invention

[0005] The main objective of this invention is to provide a high-strength tear-resistant fabric, which aims to solve at least one of the following technical problems: the production cost of existing webbing made from single high-strength polyethylene fibers or aramid fibers is high; when high-strength polyethylene fibers or aramid fibers are blended with other lower-priced fibers, it is difficult to determine the type of lower-priced fiber; and the resulting blended fabric has poor tear resistance.

[0006] To achieve the above objectives, the present invention provides a high-strength tear-resistant fabric, comprising:

[0020] Furthermore, the polyethylene filament and polyester filament in the second fabric yarn are twisted, and the twisting is either in the "S" direction or in the "Z" direction.

[0021] Furthermore, when the second fabric yarn is an untwisted multifilament yarn or a twisted multifilament yarn, the mass percentage of the polyethylene filament in the second fabric yarn is 40% to 57%.

[0022] Furthermore, the linear density of the polyethylene filament is 60 to 400 denier, and the linear density of the polyester filament is 900 to 1000 denier.

Detailed Implementation

[0032] The various aspects of the present invention will be further described in detail below.

[0033] Unless otherwise defined or stated, all technical and scientific terms used herein have the same meaning as are familiar to a user skilled in the art. Furthermore, any methods and materials similar to or equivalent to those described herein may be applied to the methods of this invention.

[0034] Unless otherwise expressly specified and limited, the term "or" as used in this invention includes the relationship of "and". "And" is equivalent to the Boolean logic operator "AND", and "or" is equivalent to the Boolean logic operator "OR", with "AND" being a subset of "OR".

[0035] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of this disclosure.

[0036] In this invention, the terms "mainly composed of" and "composed of" are included in the terms "containing", "comprising" or "including".

[0037] Unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediate medium, or a connection within two elements or an interaction between two elements. Users of ordinary skill in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0038] For example, if an element (or component) is referred to as being on, coupled to, or connected to another element, then the element may be directly formed on, coupled to, or connected to the other element, or there may be one or more intermediate elements between them. Conversely, if the expressions "directly on," "directly coupled to," and "directly connected to" are used herein, then it indicates that there is no intermediate element. Other terms used to describe relationships between elements should be interpreted similarly, such as "between" and "directly between," "attached" and "directly attached," "adjacent" and "directly adjacent," etc.

[0039] Additionally, it should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a particular component, respectively. It is understood that these terms are used here to describe the relationship of one element, layer, or region relative to another element, layer, or region, as shown in the accompanying drawings. These terms should also encompass other orientations of the device in addition to those described in the accompanying drawings.

[0040] Other aspects of the invention will be apparent to those skilled in the art from the disclosure herein.

[0041] To more clearly illustrate the technical solutions in the embodiments of this disclosure or the prior art, specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For users skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0042] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this disclosure. The drawings only show components relevant to this application and are not drawn according to the actual number, shape, and size of the components in the actual implementation. In the actual implementation, the form, quantity, and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex. For example, the thickness of the elements in the drawings may be exaggerated for clarity.

[0043] Because existing fabrics made from single high-strength polyethylene fibers or aramid fibers have high production costs, blending high-strength polyethylene fibers or aramid fibers with other lower-priced fibers presents technical problems such as difficulty in determining the lower-priced fiber types and poor tear resistance of the resulting blended fabrics.

[0044] To achieve the above objectives, as shown in the appendix Figure 1 As shown, the present invention proposes a high-strength tear-resistant fabric, comprising:

[0045] First fabric yarn 1, the first fabric yarn 1 is polyester filament yarn;

[0046] The second fabric yarn 2 is a multifilament yarn, which includes polyethylene filament and polyester filament.

[0047] In the fabric, the mass percentage of the polyethylene filament is not less than 15% and not more than 50%.

[0048] It should be noted that the mass fraction of polyethylene terephthalate (PET) in the polyester filament is greater than 85%. Suitable examples of PET for the preparation of polyester filaments can be found in US patents US5235893B2 and US6395386B2.

[0049] It should be noted that the term "fabric" describes a structure that may include one or more fiber layers, which may or may not be attached or bonded together. The term "filament" refers to an elongated fiber whose length is much greater than its width and height. The cross-section of the filaments described in this disclosure can be circular or irregular, such as elliptical, with filaments having a substantially circular cross-section being the most preferred. The term "multifilament" is a combination of multiple monofilaments, essentially a "filament bundle," wherein the monofilaments are filaments.

[0050] It should be noted that the term "denier (D)" refers to the unit of linear density, equal to the mass (grams) of 9000 meters of fiber. The "tensile modulus" of a fiber is a material property representing its resistance to deformation, referring to the rate of change in strength, expressed in grams per denier (g / d), while the change in strain is expressed as a fraction of the original fiber length (inches per inch).

[0051] The polyethylene filament and polyester filament should have a suitable range of linear densities. The suitable linear density of the polyethylene filament may be about 40 to 500 deniers, or about 50 to 450 deniers, or about 60 to 400 deniers, or about 70 to 350 deniers, or about 80 to 300 deniers, or about 90 to 250 deniers, or about 100 to 200 deniers, or about 110 to 150 deniers; the suitable linear density of the polyester filament may be about 600 to 1300 deniers, more preferably about 650 to about 1250 deniers, even more preferably about 700 to about 1200 deniers, even more preferably about 750 to 1150 deniers, even more preferably about 800 to 1100 deniers, even more preferably about 850 to 1050 deniers, even more preferably about 900 to 1000 deniers. In a preferred embodiment, the polyethylene filament has a linear density of about 60 to 400 denier, or about 70 to 400 denier, or about 80 to 400 denier, or about 90 to 400 denier, or about 100 to 400 denier, or about 110 to 400 denier; and the polyester filament has a linear density of about 900 to 1000 denier, or about 910 to 1000 denier, or about 920 to 1000 denier, or about 930 to 1000 denier, or about 940 to 1000 denier, or about 950 to 1000 denier.

[0052] The minimum tensile modulus of the polyethylene filament is at least 155 g / d, and preferably has a breaking energy of at least about 9 J / g or higher, as measured by ASTM D2256.

[0053] For polyester or polyethylene yarns, the corresponding filament yarns have better strength than staple fiber yarns. This is mainly because filaments have higher continuity and are easier to form a tighter fiber structure during processing, thereby improving the strength and tear resistance of the fabric. In contrast, staple fiber yarns have poorer interweaving between fibers and are more prone to breakage, which can have an adverse effect on the strength of the fabric.

[0054] In a preferred embodiment, the elongation of the fabric is from about 1% to about 10%.

[0055] In a preferred embodiment, the first fabric yarn 1 is a weft yarn, and the second fabric yarn 2 is a warp yarn.

[0056] It should be noted that the second fabric yarn 2 is placed in the fabric as a warp yarn, thereby giving the fabric the desired tensile strength and tear resistance. The fabric can be obtained by weaving or knitting. "Weaving" is intended to include any fabric made by weaving; that is, at least two yarns are typically interlaced or interwoven at right angles. Generally, such fabrics are made by interlacing one set of yarns called warp yarns with another set of yarns called weft yarns or weft threads. Woven fabrics can have virtually any weaving pattern, such as plain weave, four-warp broken satin weave, square plain weave, satin weave, twill weave, unbalanced weave, etc. Plain weave is the most common, in which the first fabric yarn 1 and the second fabric yarn 2 are woven together at orthogonal 0° / 90° directions. "Knitting" is intended to include structures formed by interlocking a series of loops of one or more yarns using needles or thread, such as warp-knitted fabrics (e.g., Trico warp-knitted fabrics, Milanese warp-knitted fabrics, or Rachel warp-knitted fabrics) and weft-knitted fabrics (e.g., circular or plain knitted fabrics).

[0057] As a preferred embodiment, see the attached document. Figure 2 As shown, the second fabric yarn 2 is an untwisted multifilament yarn.

[0058] In a preferred embodiment, the core of the untwisted multifilament yarn is the polyester filament, and the covering yarn of the untwisted multifilament yarn is the polyethylene filament, wherein the covering yarn at least partially covers the core.

[0059] It should be noted that the covering yarn is designed to enhance the strength and tear resistance of the untwisted multifilament yarn and to protect the yarn core. The covering yarn may consist of at least a single polyethylene filament to meet the needs of practical application scenarios.

[0060] In a preferred embodiment, when the second fabric yarn 2 is an untwisted multifilament yarn, the mass percentage of the polyethylene filament is about 40% to about 57%, more preferably about 45% to about 55%, even more preferably about 49% to about 50%, and even more preferably about 50%.

[0061] In a preferred embodiment, the surface of the coating line is provided with a hydrophobic and oleophobic coating.

[0062] It should be noted that the polyester filament, serving as the core yarn, consists of at least a single polyester filament. This arrangement was not intentionally designed to provide strength and tear resistance in conjunction with the covering yarn. However, the inventors unexpectedly discovered that, under certain conditions, the fabric containing the aforementioned core yarn and covering yarn exhibits excellent strength and tear resistance, which will be described later. Furthermore, the hydrophobic and oleophobic coating allows the second fabric yarn 2 to maintain a certain degree of self-cleaning properties. This makes the fabric more convenient to use, especially when used as animal bite restraint webbing or outdoor climbing safety webbing, as it can prevent stains from adhering to the fabric to a certain extent.

[0063] In a preferred embodiment, the polyethylene monofilament is a high-performance polyethylene filament.

[0064] It should be noted that the high-performance polyethylene filaments enable an elastic response to loads applied to the fabric, while simultaneously limiting the overall stretching of the fabric. Preferably, the high-performance polyethylene filaments are filaments containing ultra-high molecular weight polyethylene (UHMWPE) fibers (e.g., or Tekmilon TM Suitable examples of ultra-high molecular weight polyethylene (UHMWPE) for the preparation of filament fibers can be found in US patents US4411854B2, US4413110B2, and US 4422993B2.

[0065] As a preferred embodiment, see the attached document. Figure 3 As shown, the second fabric yarn 2 is a twisted multifilament yarn.

[0066] It should be noted that the polyethylene filament and polyester filament in the second fabric yarn 2 can be twisted using conventional twisting equipment and joined together using conventional twisting techniques, so that the polyethylene filament and polyester filament are in a double helix shape. The polyethylene filament used for twisting is at least a single strand; similarly, the polyester filament used for twisting is at least a single strand.

[0067] In a preferred embodiment, the polyethylene filament and polyester filament in the second fabric yarn 2 are twisted, either in an "S" direction or a "Z" direction. For example, a single polyethylene filament and a single polyester filament are twisted in an "S" direction or a "Z" direction to form a twisted yarn bundle. It should be noted that twisting can increase the strength of the twisted yarn bundle.

[0068] In a preferred embodiment, the polyethylene monofilament is a high-performance polyethylene filament.

[0069] In a preferred embodiment, when the second fabric yarn 2 is a multifilament yarn or an untwisted multifilament yarn, the mass percentage of the polyethylene filament in the second fabric yarn 2 is about 40% to about 57%, more preferably about 45% to about 55%, even more preferably about 49% to about 50%, and even more preferably about 50%.

[0070] It should be noted that the inventors of this disclosure have also unexpectedly discovered that when the mass percentage of the polyethylene filament in the fabric is about 20% to 25%, the fabric composed of the second fabric yarn 2, which is presented in the form of twisted multifilament yarn or twisted multifilament yarn, and the first fabric yarn 1 has particularly desirable strength and tear resistance.

[0071] As a preferred embodiment, the fabric is webbing, especially animal bite restraint webbing or outdoor climbing safety webbing.

[0072] It should be noted that at present, the unit price of polyethylene fiber and aramid fiber is more expensive than that of polyamide fiber and polyester fiber. By adopting the technical solution disclosed herein, it is possible to maximize the reduction of fabric production costs while ensuring fabric strength and tear resistance.

[0073] Example 1

[0074] The following embodiments and comparative examples (taking animal anti-tear restraint webbing as an example) are only for further illustrating that the technical solution of this disclosure can achieve the technical effect of maximizing the reduction of fabric production costs while ensuring fabric strength and tear resistance.

[0075] Experiment Name: Pet Product Bite Mark Durability Test

[0076] Experimental procedure:

[0077] 1. Place the sample webbing between the bite-resistant jaws;

[0078] 2. Apply a bite force of 350 pounds (equivalent to the bite force of a medium-sized dog) to the sample webbing, and then release the sample webbing;

[0079] 3. Repeat the above biting and releasing actions 1000 times;

[0080] 4. Observe once every 200 bites and after release;

[0081] 5. Evaluate whether the sample weave has obvious damage or exposed holes after the test.

[0082] Note: The sample webbing is sample C. The first fabric yarn 1 of sample C is the weft yarn, which is a polyester filament yarn with a linear density of 1000 denier. The second fabric yarn 2 is the warp yarn, which is formed by twisting polyester filament with a linear density of 1000 denier and polyethylene filament with a linear density of 400 denier. The width of sample C is 25 mm, and the thickness is 2.7 mm. The mass percentage of ethylene filament in the second fabric yarn 2 is approximately 50% to 57%, and the mass percentage of polyethylene filament in the webbing is approximately 20% to 25%.

[0083] Reference Appendix Figure 4 The test results are as follows: After the test, a slight dent was observed on the webbing of sample C at the interlocking position. After the test, there were no cracks, internal exposure, tearing or loss of function on the surface of sample C webbing.

[0084] Comparative Example 1

[0085] Note: The test procedure is the same as in Example 1. The sample webbing is sample B, where the weft yarn is polyester filament yarn with a linear density of 1000 denier, and the number of weft yarns is the same as in Example 1; the warp yarn is formed by twisting polyester filament with a linear density of 1000 denier and polyethylene filament with a linear density of 400 denier, and the number of warp yarns is the same as in Example 1. Sample C has a width of 25 mm and a thickness of 2.7 mm. The mass percentage of polyethylene filament in the warp yarn is greater than 57%, and the mass percentage of polyethylene filament in the webbing is greater than 25%.

After the test, there were no cracks on the surface of sample B webbing, no obvious internal exposure, tearing, or loss of function.

[0087] It should be noted that, for pure polyester filament yarn and polyethylene filament yarn, the strength of polyethylene filament yarn should be greater than that of polyester filament yarn. However, the inventors unexpectedly discovered in Example 1 and Comparative Example 1 that increasing the mass percentage of polyethylene filament in the warp yarn (multifilament yarn) did not give the B sample webbing better tear resistance than the C sample webbing. On the contrary, the test results of Comparative Example 1 were worse than those of Example 1.

[0088] Comparative Example 2

[0089] Note: The test procedure is the same as in Example 1. The sample webbing is sample E, and both the weft and warp yarns of sample E are made of polyethylene filaments with a linear density of 400 denier. The width of sample E is 25 mm and the thickness is 2.5 mm.

[0095] Note: The test procedure is the same as in Example 1. The sample webbing is sample D, which is made of nylon / Kevlar filaments with a linear density of 390 denier for both the weft and warp yarns. The width of sample D is 25 mm and the thickness is 2.4 mm.

[0096] Reference Appendix Figure 8 The test results are as follows: After the test, moderate fabric breakage was observed at the interlocking position on sample D webbing. Sample D webbing showed internal exposure, tearing, or loss of function after the test.

[0097] Comparative Example 5

[0098] Note: The test procedure is the same as in Example 1. The sample webbing is sample F webbing, in which the weft yarn is made of nylon / Kevlar filament with a linear density of 840 denier; the warp yarn is formed by twisting nylon filament with a linear density of 840 denier and polyethylene filament with a linear density of 400 denier. The sample F webbing is 25 mm wide and 2.4 mm thick.

[0099] Reference Appendix Figure 9 The test results are as follows: After the test, slight fabric breakage was observed at the interlocking position on sample F. After the test, there were no cracks on the surface of sample F, no obvious internal exposure, tearing, or loss of function.
