Description

Technical Field

[0001] The present invention relates to the technical field of functional fabrics, and in particular to a high-strength, wear-resistant and lightweight fabric and a preparation method and application thereof. Background Art

[0002] With the rapid development of the textile industry, the market demand for functional fabrics is growing, especially in the fields of outdoor sports, military equipment, high-end clothing, etc., which put forward higher requirements on the strength, wear resistance and service life of fabrics. However, the high-strength and wear-resistant fabrics currently on the market still have certain technical bottlenecks in terms of performance, lightweight, comfort, etc. This is because lightweight materials are usually difficult to simultaneously meet the balance of high strength, wear resistance and comfort.

[0003] Therefore, providing an innovative method for preparing high-strength and wear-resistant fabrics, wherein the prepared fabrics have good mechanical properties and durability while also taking into account the characteristics of lightness and versatility, and thus can meet the use requirements of various extreme environments and high-demand scenarios, is still a problem to be urgently solved in this field. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a high-strength wear-resistant lightweight fabric and a preparation method and application thereof. The fabric prepared by the method provided by the present invention has a light overall weight and excellent tear strength and wear resistance.

[0005] To achieve this object, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a method for preparing a high-strength, wear-resistant and lightweight fabric, the preparation method comprising the following steps: (1) Plasma modification treatment of ultra-fine denier ultra-high molecular weight polyethylene yarn under the action of argon; (2) mixing and modifying the ultra-fine denier ultra-high molecular weight polyethylene yarn obtained after the plasma modification treatment in step (1) and a finishing agent; (3) The mixed modified ultra-fine denier ultra-high molecular weight polyethylene yarn obtained in step (2) is interwoven with the ultra-fine denier N66 yarn to obtain the high-strength, wear-resistant and lightweight fabric.

[0006] In the present invention, the ultra-fine denier ultra-high molecular weight polyethylene yarn is first subjected to plasma modification treatment, which can greatly increase the surface roughness of the polyethylene yarn. The molecular chain of the polyethylene yarn is composed of long-chain polyethylene (-CH 2 -CH 2-) repeating units, argon gas ionization produces high-density argon ions and other high-energy particles, which bombard the polyethylene yarn surface at high speed, causing some CH molecular chains to break, and the free radicals generated by the break combine with the free radicals on the adjacent molecular chains to form new CC bonds, connecting the originally independent molecular chains into a three-dimensional network structure, achieving overall good interaction, which is beneficial to improving the wear resistance and tear strength of the resulting fabric; at the same time, it is also beneficial to its combination and adsorption with the finishing agent, so that it can absorb more finishing agents in the process of mixing and modification with the finishing agent for sufficient modification, further improving the wear resistance and tear strength of the resulting fabric.

[0007] The present invention adopts the method of first subjecting the ultra-fine denier ultra-high molecular weight polyethylene yarn to plasma modification and finishing agent modification in sequence, and then interweaving it with N66 yarn to obtain the fabric, which not only ensures the lightweight of the material, but also can effectively improve the tear strength and wear resistance of the obtained fabric, thereby well solving the problem that the existing lightweight materials are difficult to simultaneously meet the balance of high strength, wear resistance and comfort, and can thus meet the use requirements of various extreme environments and high-demand scenarios.

[0008] The following are preferred technical solutions of the present invention, but are not intended to limit the technical solutions provided by the present invention. Through the following preferred technical solutions, the objectives and beneficial effects of the present invention can be better achieved and realized.

[0009] As a preferred technical solution of the present invention, in the mixed modification of step (2), the bath ratio of the ultrafine denier ultrahigh molecular weight polyethylene yarn obtained after plasma modification in step (1) to the finishing agent is 1:(35-45), wherein (35-45) can be, for example, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44 or 45, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the said range.

[0010] In step (2) of the present invention, by adjusting the bath ratio of the ultrafine denier ultrahigh molecular weight polyethylene yarn obtained after plasma modification in step (1) to the finishing agent to be 1:(35-45), the ultrafine denier ultrahigh molecular weight polyethylene yarn can be more fully mixed and modified, so that the obtained fabric has better wear resistance and tear strength. When the bath ratio is too high or too low, it may cause uneven distribution of the finishing agent on the yarn surface, thereby causing inconsistency in yarn performance or failure to achieve ideal performance, thereby reducing the wear resistance and tear strength of the obtained fabric.

[0014] The preparation method provided by the present invention is more preferably applicable to 20D ultra-fine denier ultra-high molecular weight polyethylene yarn and 15-20D ultra-fine denier N66 yarn materials, which are lighter in weight and stronger in strength.

[0015] As a preferred technical solution of the present invention, in step (1), the gas pressure of the plasma modification treatment is 60-80 Pa, for example, it can be 60 Pa, 62 Pa, 64 Pa, 66 Pa, 68 Pa, 70 Pa, 72 Pa, 74 Pa, 76 Pa, 78 Pa or 80 Pa, as well as specific point values ​​between the above point values.

[0018] The present invention accurately controls the plasma treatment process parameters for the yarn used (15-20D ultra-fine denier ultra-high molecular weight polyethylene yarn). Within the parameter range of the present invention, it can not only ensure the effective effect of plasma on the yarn surface, but also avoid poor treatment effect or damage to the structure of the yarn itself due to excessively high or low parameters, thereby better achieving the effect of light overall weight of the fabric, excellent tear strength and wear resistance.

Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific points included in the range.

[0026] In the present invention, the polyurethane may be, for example, any one of polyester polyurethane, polyether polyurethane, polycarbonate polyurethane or aqueous polyurethane dispersion, or a combination of at least two thereof.

[0027] Preferably, the cross-linking agent comprises polysiloxane.

[0030] It should be noted that there is no special restriction on the types of fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ester, naphthalene sulfonic acid dispersant and polycarboxylic acid dispersant in the present invention, and the fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ester, naphthalene sulfonic acid dispersant and polycarboxylic acid dispersant commonly used in the art are all applicable.

[0035] The mass ratio of polyurethane to adhesive in the finishing agent of the present invention is (1.25-2.5):1, which can significantly improve the tear strength and wear resistance of the obtained fabric.

[0077] The performance tests of Examples 1-13 and Comparative Examples 1-2 were performed using the following test methods / standards: Abrasion resistance test: refer to GB / T 21196.2-2007 "Determination of the abrasion resistance of textiles by the Martindale method - Part 2: Determination of specimen damage"; Strength test: refer to GB / T 3917.2-2009 "Tear properties of textile fabrics - Part 2: Determination of tear strength of trouser-shaped specimens (single seam)"; Weight test method: Use electronic balance to weigh.

[0078] The test results are shown in Table 2.

[0079] Table 2

[0080] The test results show that: (1) It can be seen from Examples 1 to 13 that the present invention adopts a specific preparation method of first subjecting the ultra-fine denier ultra-high molecular weight polyethylene yarn to plasma modification and then mixing it with a finishing agent for modification, so that the obtained fabric can have excellent wear resistance and tear resistance while ensuring a relatively light weight (30-35 GSM). The wear resistance is 210,000-320,000 revolutions, the radial strength is 24-32 N, and the weft strength is 24-38 N.

[0081] (2) By comparing Example 1 with Examples 4 and 5, it can be seen that the present invention can make the obtained fabric have better wear resistance and tear strength by further limiting the bath ratio of the ultra-fine denier ultra-high molecular weight polyethylene yarn after plasma treatment and the finishing agent during the finishing agent modification process.

[0082] (3) By comparing Example 1 with Examples 6-9, it can be seen that the present invention further limits the gas pressure and power in the plasma modification process, thereby achieving the purpose of ensuring the effective effect of plasma on the yarn surface while avoiding poor treatment effect or damage to the yarn structure itself due to excessively high or low parameters, thereby better achieving the overall light weight of the fabric, excellent tear strength and wear resistance.

[0083] (4) By comparing Example 1 with Examples 10-13, it can be seen that the mass ratio of polyurethane to adhesive in Example 12 is lower than 1.25:1, and the mass ratio of polyurethane to adhesive in Example 13 is higher than 2.5:1. The wear resistance and tear strength of the fabrics obtained by both are lower than those of Examples 10 and 11, indicating that the present invention can significantly improve the tear strength and wear resistance of the fabric obtained by further limiting the mass ratio of polyurethane to adhesive in the finishing agent to (1.25-2.5):1.

[0084] (5) By comparing Example 1 with Comparative Example 1, it can be seen that the present invention, through a specific preparation method of first subjecting the ultra-fine denier ultra-high molecular weight polyethylene yarn to plasma modification and then mixing it with a finishing agent for modification, can ensure that the obtained fabric has excellent wear resistance and tear strength while ensuring its lightness.

[0085] (6) By comparing Example 1 with Comparative Example 2, it can be seen that in the preparation method of the fabric of the present invention, by subjecting the ultra-fine denier ultra-high molecular weight polyethylene yarn to plasma modification treatment, the wear resistance and tear strength of the resulting fabric can be significantly improved while ensuring the lightweight of the resulting fabric. Without this step, the above-mentioned excellent effect cannot be obtained.

[0086] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention are within the protection scope and disclosure scope of the present invention.
