Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, in particular to a heat-resistant tablecloth and a preparation process thereof. BACKGROUND

[0002] A tablecloth is a textile covering a table, mainly serving the purposes of aesthetics and protection of the table.

[0003] Using a tablecloth on a dining table can reduce the heat of food transferred to the table, and avoid soup and oil from dropping on the table, thereby increasing the protection of the table and facilitating cleaning.

[0004] After food is heated, if a large amount of water exists inside the food, water vapor is formed during the heating of the food, and people around can determine the temperature of the food through the water vapor. However, for fried food, the water content inside the food is small, and little water vapor is generated, so it is difficult to determine the temperature of the food at this time. Often, because of the misjudgment of the temperature of the food, the phenomenon of scalding occurs when contacting the container or the food.

[0005] Therefore, the present application provides a tablecloth capable of prompting the temperature of an object located on the tablecloth. SUMMARY

[0006] The present application is to solve the problems in the prior art, and provides a heat-resistant tablecloth and a preparation process thereof.

[0007] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0008] The heat-resistant tablecloth comprises, in sequence, a base layer, a light-transmitting heat-resistant layer, and a light-transmitting waterproof layer. The light-transmitting heat-resistant layer is formed with a plurality of grooves on the side facing the base layer. The grooves are filled with light-transmitting heat-conducting gel. The light-transmitting heat-conducting gel is connected to the base layer. The base layer is impregnated with a heat-induced color change finishing agent.

[0009] The present application is further provided that the heat-induced color change finishing agent comprises, by mass percentage: 15-40% heat-induced color change microcapsule powder, 6-20% water-based PU adhesive, 2-5% penetrating agent JFC, and the balance of distilled water.

[0010] The present application is further provided that the base layer is woven from fiber bundles in a plain weave manner. The fiber bundles comprise core yarns and wrapping yarns. The wrapping yarns are spirally wrapped outside the core yarns. The wrapping yarns are twisted from polyester profiled fibers with a cross-section in the shape of a cross. The core yarns are twisted from a plurality of para-aramid fibers.

[0011] The application further provides that components of the light-transmitting waterproof layer are PVDF-HEP, nano silicon oxide, acetone and heptadecafluorodecyltrimethoxysilane, and the mass ratio of the PVDF-HEP and the nano silicon oxide is 1-2:2-1.

[0012] The application further provides that the length directions of the grooves are consistent, and the length directions of the grooves are perpendicular to the length direction of the tablecloth.

[0013] The application further provides that the side, away from the light-transmitting heat-resistant layer, of the base layer is attached with a plurality of silica gel protrusions.

[0014] The preparation process of the heat-resistant tablecloth comprises the following steps:

[0015] S1, preparing a light-transmitting heat-resistant layer, pouring UV resin into a mold, irradiating the mold by a UV lamp, curing the UV resin to form a light-transmitting heat-resistant layer with grooves;

[0016] S2, curing light-transmitting heat-conducting gel, coating the light-transmitting heat-conducting gel on the grooves of the light-transmitting heat-resistant layer obtained in S1, and heating and drying the light-transmitting heat-resistant layer to complete the curing of the light-transmitting heat-conducting gel;

[0017] S3, spraying a light-transmitting waterproof layer, adding PVDF-HEP and nano silicon oxide into acetone, then adding heptadecafluorodecyltrimethoxysilane into the acetone while heating and stirring to obtain a spraying liquid, and spraying the spraying liquid to the side, without grooves, of the light-transmitting heat-resistant layer obtained in S2 by a spray gun to form the light-transmitting waterproof layer;

[0018] S4, finishing the base cloth, adding heat-induced color-changing microcapsule powder, water-based PU adhesive and penetrating agent JFC into distilled water, mixing and stirring to obtain a heat-induced color-changing finishing agent, immersing the base cloth into the heat-induced color-changing finishing agent, repeatedly rolling the base cloth by a small roller to complete the immersion and padding of the base cloth, baking the base cloth to complete the finishing of the base layer;

[0019] S5, compounding, brushing glue on the base layer obtained in S4, and rolling and pressing the base layer and the light-transmitting heat-resistant layer completed by spraying in S3 by a high-temperature roller to bond the base layer and the light-transmitting heat-resistant layer, and completing the production of the tablecloth.

[0020] The application further provides that, in S4, after completing the baking of the base cloth, the base cloth is soaped, and after completing the soaping, the base cloth is cleaned by clean water and then dried.

[0021] In summary, the application has the following beneficial effects:

[0022] When the container with food is placed on the tablecloth, the heat of the food will be transferred to the tablecloth through the container, the light-transmitting heat-resistant layer will reduce the heat transferred to the light-transmitting heat-conducting gel and the base layer due to the characteristics of the UV material, and the base layer will further reduce the heat transfer due to the characteristics of the para-aramid fiber, so that the heat transferred to the dining table is reduced, and the damage of the heat to the dining table is reduced.

[0023] The light-transmitting heat-conducting gel will transfer heat, increase the radiation range of heat on the tablecloth, and reduce the damage of excessive heat concentration to the tablecloth and the dining table.

[0024] The heat will be transferred in a straight line due to the distribution of the grooves, and when the heat is transferred to the base layer, the base layer will change color under the action of the thermochromic finishing agent, so that a plurality of color stripes will be formed on the tablecloth corresponding to the container, and the length and color depth of the color stripes will remind people around the temperature of the container.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. In the description of the application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all embodiments.

[0030] As Figure 1 and Figure 2As shown, the present application provides a heat-resistant tablecloth, which can be laid on the surface of the dining table to avoid the contact of food containers with the dining table and protect the dining table. The heat-resistant tablecloth comprises, in sequence, a base layer 1, a light-transmitting heat-resistant layer 2 and a light-transmitting waterproof layer 3. The base layer 1 and the light-transmitting heat-resistant layer 2 are bonded by hot pressing with glue, and the light-transmitting waterproof layer 3 is arranged on the light-transmitting heat-resistant layer 2 by spraying. The light-transmitting heat-resistant layer 2 is made of UV resin, and the side of the base layer 1 away from the light-transmitting heat-resistant layer 2 is adhered with a plurality of silica gel protrusions 4. The UV resin and the silica gel material both have good heat insulation effect. When a container containing food is placed on the tablecloth, the light-transmitting heat-resistant layer 2 and the silica gel protrusions 4 can reduce the heat transferred to the dining table, thereby protecting the dining table. At the same time, the silica gel protrusions 4 can increase the relative friction between the dining table and the tablecloth, increase the anti-skid effect of the tablecloth, and ensure the stability of the position of the tablecloth on the dining table.

[0031] The components of the light-transmitting waterproof layer 3 comprise PVDF-HEP, nano silicon oxide, acetone and heptadecafluorodecyltrimethoxysilane, and the mass ratio of PVDF-HEP to nano silicon oxide is 1-2:2-1. The use of PVDF-HEP and nano silicon oxide makes the light-transmitting waterproof layer 3 have hydrophobic and oleophobic effects, reduces the probability of soup and oil adhering to the tablecloth, facilitates the cleaning of soup and oil, reduces the probability of soup and oil penetrating into the base layer 1, reduces the corrosion of soup and oil to the base layer 1, and prolongs the service life of the tablecloth.

[0032] As shown, Figure 3 The base layer 1 is woven by fiber bundles 5 in a plain weave manner, wherein the fiber bundles 5 comprise core yarns 6 and wrapping yarns 7, the wrapping yarns 7 are spirally wrapped outside the core yarns 6, and the wrapping yarns 7 are twisted from polyester profiled fibers 8 with a cross-section structure, and the core yarns 6 are twisted from a plurality of para-aramid fibers 9. The para-aramid fibers 9 have good heat insulation effect, which can further reduce the heat transferred to the dining table.

[0033] As shown, Figure 3 The base layer 1 is impregnated with a heat-induced color change finishing agent through a cloth padding process. The components of the heat-induced color change finishing agent, by mass percentage, comprise 15-40% heat-induced color change microcapsule powder, 6-20% water-based PU adhesive, 2-5% penetrating agent JFC and the balance of distilled water. The heat-induced color change microcapsules adhere to the surface of the polyester profiled fibers 8. When the base layer 1 is heated, the heat-induced color change microcapsules will change color, thereby causing the base layer 1 to change color. Through the change of color, people around are reminded to pay attention to the temperature of the container, thereby achieving a warning effect and reducing the probability of burns. Since the surface of the polyester profiled fibers 8 has multiple channels due to the cross structure, the channels increase the surface area of the polyester profiled fibers 8, which can increase the heat-induced color change microcapsules adhering to the surface of the polyester profiled fibers 8, increase the color change degree of the base layer 1, and increase the warning effect.

[0034] As shown in Figure 2 The side of the light-transmitting heat-resistant layer 2 facing the base layer 1 is formed with a plurality of grooves 10, the length direction of the plurality of grooves 10 is consistent, and the length direction of the grooves 10 is perpendicular to the length direction of the tablecloth. The grooves 10 are filled with light-transmitting heat-conducting gel 11, which is connected to the base layer 1. When a container containing food is placed on the tablecloth, the heat of the container will be transmitted to the light-transmitting heat-conducting gel 11 after being blocked by the light-transmitting heat-resistant layer 2. The light-transmitting heat-conducting gel 11 will transmit heat to the light-transmitting heat-conducting gel 11 in the same groove 10, with the position of the container as the center, which can increase the radiation range of the heat on the tablecloth and reduce the damage to the tablecloth and the table caused by excessive concentration of heat.

[0035] The light-transmitting heat-conducting gel 11 is distributed in a straight line, so that the heat of the container is also transmitted in a straight line. When the heat is transmitted to the base layer 1, the base layer 1 will continue to change color under the action of the heat-induced color-changing finish, so that a plurality of color stripes will be formed on the tablecloth corresponding to the container. The higher the temperature of the light-transmitting heat-conducting gel 11, the greater the color change degree of the corresponding position of the base layer 1, and the less heat the light-transmitting heat-conducting gel 11 receives. The smaller the range of heat transmission of the light-transmitting heat-conducting gel 11 in the same groove 10. In this way, people around can judge the temperature of the container by the length of the color stripes and the color depth of the color stripes. At the same time, due to the change range of the color not being limited to the surrounding of the container, people around can more easily find the color stripes.

[0036] The preparation process of the heat-resistant tablecloth includes the following steps:

[0037] S1, preparing a light-transmitting heat-resistant layer 2, pouring UV resin into a mold, irradiating the mold with a UV lamp, curing the UV resin to form a light-transmitting heat-resistant layer 2 with grooves 10;

[0038] S2, curing the light-transmitting heat-conducting gel 11, coating the light-transmitting heat-conducting gel 11 in the grooves 10 of the light-transmitting heat-resistant layer 2 obtained in S1, and heating and drying the light-transmitting heat-resistant layer 2 to complete the curing of the light-transmitting heat-conducting gel 11;

[0039] S3, spraying a light-transmitting waterproof layer 3, adding PVDF-HEP and nano silicon oxide to acetone, then adding heptadecafluorodecyltrimethoxysilane to the acetone while heating and stirring to obtain a spraying liquid, and spraying the spraying liquid to the side of the light-transmitting heat-resistant layer 2 obtained in S2 without grooves 10 through a spray gun to form a light-transmitting waterproof layer 3;

[0040] S4, finishing of the fabric, adding the thermochromic microcapsule powder, water-based PU adhesive, penetrating agent JFC into distilled water, mixing and stirring to obtain a thermochromic finishing agent, immersing the fabric into the thermochromic finishing agent, repeatedly rolling the fabric by a small padder to complete the padding of the fabric, baking the fabric, after the baking of the fabric, soaping the fabric, after the soaping, cleaning by clean water, and then drying, completing the finishing of the base layer 1;

[0041] S5, compounding, brushing glue on the base layer 1 obtained in S4, rolling and pressing the base layer 1 and the light-transmitting heat-resistant layer 2 completed by spraying in S3 by a high-temperature roller, so that the base layer 1 and the light-transmitting heat-resistant layer 2 are bonded, and the production of the tablecloth is completed.

[0042] In summary, the heat-resistant tablecloth provided by the embodiment reduces the damage of heat to the tablecloth and the table, and at the same time, relies on the heat of the food container to make the tablecloth form a plurality of color stripes, uses the length and color depth of the color stripes to warn and remind the surrounding people to pay attention to the temperature of the container and reduce the probability of scalding.
