Description

Technical Field

[0001] This invention belongs to the field of fabric processing technology, specifically relating to a multifunctional field combat uniform fabric and its preparation method. Background Technology

[0002] Field combat uniforms are generally used for outdoor combat operations and need to have tensile strength and warmth retention properties that ordinary fabrics do not have, in order to adapt to the harsh outdoor environment.

[0003] Typical field combat uniform fabrics have good abrasion resistance and will not pill or snag after long-term wear. However, in dense jungles, combatants are often surrounded by low shrubs, some of which have sharp thorns. These thorns can easily penetrate the fabric of the combat uniform and embed themselves in the flesh, causing bleeding or poisoning and increasing the danger of combat. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional field combat uniform fabric and its preparation method in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] This invention provides a method for preparing a multifunctional field combat uniform fabric, the combat uniform fabric including a protective layer, an abrasion-resistant layer sewn to the top of the protective layer, and an insulation layer sewn to the bottom of the protective layer;

[0007] The protective layer is formed by printing multiple interlocking connectors using 3D printing technology with adhesive. Each connector includes a connecting ring. Two Y-shaped limiting rods are integrally formed on the outer side of the connecting ring. The connecting ring has slots that fit into the Y-shaped limiting rods. The radius of the connecting ring is 0.2 mm.

[0008] The adhesive comprises 40-60 parts by weight of photosensitive resin.

[0009] As a further optimization of the present invention, the binder further includes, by weight, 8-12 parts titanium dioxide, 20-30 parts volcanic rock particles, 5-10 parts aconitine and 3-6 parts crosslinking agent.

[0010] As a further optimization of the present invention, the crosslinking agent is one of dicumyl peroxide or diethylenetriamine.

[0011] As a further optimization of the present invention, the wear-resistant layer 3 is made of a blend of 30%-45% cotton fiber, 20%-30% bamboo charcoal fiber and 15%-25% polyester fiber; the heat-insulating layer 2 is made of a blend of 30%-45% cashmere fiber, 5%-10% rabbit hair fiber, 20%-25% alpaca cashmere fiber and 15%-25% spandex fiber.

[0012] This invention also provides a method for preparing a multifunctional field combat uniform fabric, comprising the following steps:

[0013] S1, after mixing and stirring diatomaceous earth powder, titanium dioxide and volcanic rock particles, the mixture is ground in a nano-grinding machine to obtain a mixed powder;

[0014] S2, the mixed powder obtained in step S1 is put into a container containing photosensitive resin and heated and stirred. During the heating and stirring, aconitine and crosslinking agent are added. After thorough mixing, the adhesive is obtained.

[0015] S3, add the adhesive into the 3D printer, and use 3D printing technology to print multiple interlocking connectors as a protective layer;

[0016] S4, a wear-resistant layer is obtained by blending 30%-45% cotton fiber, 35%-50% bamboo charcoal fiber and 25%-35% polyester fiber; a heat-insulating layer is obtained by blending 30%-45% cashmere fiber, 5%-10% rabbit hair fiber, 20%-25% alpaca cashmere fiber and 15%-25% spandex fiber.

[0017] S5, the abrasion-resistant layer and the thermal insulation layer are sewn to the protective layer in sequence to obtain the combat uniform fabric.

[0018] As a further optimization of the present invention, the particle size of diatomaceous earth powder and titanium dioxide after grinding by a nano-grinding machine in step S1 is 1-3 nm.

[0019] As a further optimization of the present invention, the heating temperature in step S2 is 85-95℃; the stirring speed is 85r / min.

[0020] The beneficial effects of this invention are as follows: by sewing an abrasion-resistant layer on top and an insulation layer on the bottom of the protective layer, a combat uniform fabric is obtained. This combat uniform fabric mainly achieves tensile strength and warmth through the protective layer. The protective layer forms a barrier to prevent sharp objects from penetrating the clothing. The diatomaceous earth powder and volcanic rock particles added inside the protective layer can increase the tensile strength of the protective layer, and the volcanic rock particles can increase the warmth retention. The protective layer, printed by 3D printing technology, is located between the abrasion-resistant layer and the insulation layer, forming an air layer, which further increases the warmth retention of the fabric.

[0079] (I) Performance Testing

[0080] 1.1 The fabric samples prepared according to the methods of Examples 1-3 and Comparative Examples 1-4 were cut into 50cm×50cm sizes. The tensile properties of the samples prepared according to the methods of Examples 1-3 and Comparative Examples 1-4 were tested according to GB / T3923.2-2013 "Textiles - Tensile Properties of Fabrics - Part 2: Determination of Breaking Strength by Sampling Method".

[0081] Table 1 Product Performance Test

[0082]

[0083]

[0084] The test results are shown in Table 1 above. Examples 1-3 are superior to Comparative Examples 1-4 in terms of tensile properties, with Example 1 showing the best value.

[0085] Comparing Example 2 with Example 1, it can be seen that the only difference between Example 1 and Example 2 is the crosslinking agent used. The crosslinking agent used in Example 1 is dicumyl peroxide, while the crosslinking agent used in Example 2 is diethylenetriamine. Tensile performance testing shows that the protective layer prepared by using dicumyl peroxide as a crosslinking agent has better tensile strength and better elongation at break.

[0086] Comparing Example 3 with Example 1, it can be seen that the difference between Example 3 and Example 1 is that the protective layer made by photosensitive resin printing does not contain diatomaceous earth powder, titanium dioxide, volcanic rock particles, aconitine, and crosslinking agent. However, after tensile performance testing, it can be concluded that the protective layer made by using the mixed powder obtained in Example 1, after being proportioned, has better tensile strength and better elongation at break.

[0087] Comparing Comparative Example 1 with Example 1, it can be seen that the difference between Example 1 and Comparative Example 1 is that diatomaceous earth powder was added in Example 1, which made the fabric made in Example 1 have better tensile strength and better elongation at break.

[0088] Comparing Comparative Example 2 with Example 1, it can be seen that the difference between Example 1 and Comparative Example 2 is that volcanic rock particles were added in Example 1, which made the fabric made in Example 1 have better tensile strength and better elongation at break.

[0089] Comparing Comparative Example 3 with Example 1, it can be seen that the difference between Example 1 and Comparative Example 3 is that Comparative Example 3 adds the mixed powder, aconitine, and diisopropylbenzene peroxide to the photosensitive resin at the same time and stirs them, so that the fabric made in Comparative Example 3 is slightly inferior to that in Example 1 in terms of tensile properties.

[0090] Comparing Comparative Example 4 with Example 1, it can be seen that the difference between Example 1 and Comparative Example 4 is that Example 1 has a protective layer, which makes the fabric made in Example 1 have better tensile strength and better elongation at break.

[0091] 1.2 The samples prepared by the methods of Example 1 and Comparative Examples 1-5 were washed, and samples after washing 10, 20, 30, 40 and 50 times were selected in sequence. The thermal insulation performance of the samples prepared by the methods of Example 1 and Comparative Examples 1-5 was tested according to the international standard ASTM D1518-2014 "Method for testing thermal resistance of cotton wadding systems (hot plate method)".

[0092] Table 2 Product Performance Tests

[0093] Note: (Unit of thermal insulation performance: W / m) 2 ·K)

[0094] project 10 / time 20 / time 30 / time 40 / time 50 / time Example 1 1.5 1.5 1.4 1.4 1.4 Comparative Example 1 1.4 1.2 1.1 1 0.8 Comparative Example 2 1.4 1 0.9 0.8 0.7 Comparative Example 3 1.5 1.4 1.4 1.3 1.2 Comparative Example 4 1.3 0.9 0.7 0.6 0.5 Comparative Example 5 1.4 1 0.8 0.75 0.6

[0095] The test results are shown in Table 2 above. Comparing Example 1 and Comparative Example 1, it can be seen that the warmth retention performance of the fabric decreased after removing the diatomaceous earth powder.

[0096] A comparison of Example 1 and Comparative Example 2 shows that the warmth retention of the fabric decreases after the volcanic rock particles are removed.

[0097] A comparison of Example 1 and Comparative Example 3 shows that adding the mixed powder, aconitine, and dicumyl peroxide to the photosensitive resin simultaneously and stirring will result in a slight decrease in the fabric's warmth retention performance.

[0098] A comparison of Example 1 and Comparative Example 4 shows that the warmth retention of the fabric decreases significantly after the protective layer is removed.

[0099] A comparison of Example 1 and Comparative Example 5 shows that the protective layer made using only natural resin printing, although without the addition of diatomaceous earth powder, titanium dioxide, volcanic rock particles, aconitine, and crosslinking agent, produces a fabric with better thermal insulation performance than the fabric of Comparative Example 4 without a protective layer. This demonstrates that the protective layer composed of connectors, together with the abrasion-resistant layer and the thermal insulation layer, has a synergistic effect of heat preservation and heat storage.

[0100] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
