Description

Technical Field

[0001] This utility model relates to the field of textile composite materials technology, specifically to a self-adhesive heat-insulating towel fabric. Background Technology

[0002] In daily production and life, the need to wrap, protect, and insulate objects is widespread. For example, fragile items need to be wrapped to prevent damage during logistics and transportation; temporary insulation is needed for pipes and equipment in the industrial sector; and food and beverages need to be kept warm and fresh in daily life. Currently, meeting these needs usually relies on several traditional materials or combinations thereof.

[0003] First, ordinary terry cloth is a widely used wrapping material. It is soft, has some cushioning and moisture-absorbing properties, and can effectively prevent scratches on object surfaces. However, it has almost no heat insulation function; heat dissipates quickly through the fabric, making it unsuitable for scenarios requiring temperature maintenance. Furthermore, terry cloth itself lacks adhesiveness, requiring additional ropes, tape, or straps for securing it after wrapping. This process is cumbersome, results in poor tightness and consistency, and the securing materials are prone to loosening, leading to wrapping failure.

[0004] Secondly, professional insulation materials, such as foam plastics, glass wool, and rock wool, have good thermal insulation properties. However, these materials usually have the following problems: First, most of them are hard or loose in shape, with poor flexibility, making it difficult to fit tightly to irregularly shaped objects; second, their surfaces usually do not have self-adhesive properties, making the installation and fixing process complicated and requiring the use of tape, cable ties, or special clips, which increases the difficulty and cost of construction; third, some materials have poor appearance and may even shed lint or irritate human skin, making them unsuitable for direct contact with objects or use in home environments.

[0005] Currently, there are also materials that attempt to combine insulation layers with fabrics, but their functional designs are often relatively simple and fail to effectively address the core pain point of "easy fixation" for end users. Designs that separate insulation and fixation functions (i.e., the "insulation material + fixation auxiliary material" model) lead to problems such as complex material management, increased operational steps, and higher overall costs.

[0006] Therefore, there is an urgent need in this field for a new type of fabric that integrates multiple functions. Utility Model Content

[0007] To address the problems of existing technologies, this invention provides a self-adhesive thermal insulation terry cloth fabric. It possesses the softness, cushioning, and friendly touch of terry cloth, while also exhibiting effective thermal insulation properties. It enables quick and convenient self-fixation, eliminating the need for additional fixing materials, thereby simplifying operation, improving efficiency, and expanding application scenarios.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: First aspect, a self-adhesive heat-insulating towel fabric, the fabric comprising a towel fabric substrate and a heat-insulating layer composite with the towel fabric substrate, wherein a self-adhesive layer is provided on one or both sides of the fabric, so that the fabric has heat-insulating properties and self-adhesiveness.

[0009] In one specific embodiment of the first aspect, the insulation layer comprises at least one of a porous material, a foam material, or a textile fiber material, for delaying and reducing rapid temperature loss.

[0010] In one specific embodiment of the first aspect, the self-adhesive layer includes at least one of pressure-sensitive adhesive, hot melt adhesive, or self-adhesive film, enabling the fabric to self-adhere to the surface of objects of various shapes.

[0011] In one specific embodiment of the first aspect, the terry cloth substrate, the thermal insulation layer, and the self-adhesive layer are combined by a lamination composite process, wherein the lamination order is that the terry cloth substrate, the thermal insulation layer, and the self-adhesive layer are arranged sequentially.

[0012] In one specific embodiment of the first aspect, the lamination process includes at least one of hot-press lamination, adhesive lamination, or sewing lamination.

[0013] In one specific embodiment of the first aspect, the stacking order is to first laminate the thermal insulation layer onto the terry cloth substrate, and then apply the self-adhesive layer to the outside of the thermal insulation layer.

[0014] In one specific embodiment of the first aspect, the thickness of the insulation layer is 0.5 mm to 5 mm, and the total thickness of the self-adhesive insulation terry cloth fabric is 1 mm to 10 mm.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through its three-layer composite structure, successfully solves the problem of the single function of traditional fabrics, achieving a synergistic effect of thermal insulation and convenient self-adhesion. Existing ordinary terry cloth only possesses water absorption and wiping functions, while professional insulation materials often lack the flexibility and self-adhesion required for wrapping and fixing. This utility model integrates the terry cloth substrate, functional insulation layer, and self-adhesive layer into a single composite design, not only retaining the inherent softness, shock absorption, and skin-friendly properties of terry cloth, but also endowing it with excellent thermal insulation capabilities that delay heat loss. Simultaneously, the introduction of the self-adhesive layer allows the fabric to self-adhere and fix itself without relying on any external tools, tightly adhering to the surfaces of various irregularly shaped objects. This "three-in-one" structural innovation enables a single fabric to simultaneously possess multiple functions that previously required combining materials, fundamentally overcoming the objective shortcomings of existing technologies such as single fabric function and cumbersome operation.

[0017] 2. This composite structure brings significant improvements in technical performance, specifically in superior heat insulation, enhanced protection, excellent ease of use, and reusable durability. As experimental data shows, compared to ordinary towels, this product can reduce the surface equilibrium temperature by more than 10°C in static heat insulation tests, effectively delaying heat loss; in dynamic anti-scalding tests, it can extend the safe operation time from less than 1 minute to more than 3 minutes, significantly improving safety. Furthermore, its self-adhesive properties more than double the efficiency of wrapping operations, and its internal cushioning layer provides impact protection far exceeding that of ordinary fabrics, significantly reducing the breakage rate of fragile items. More importantly, after multiple washing tests, the fabric's heat insulation performance and structural integrity show extremely low degradation, proving that it is not a disposable product, possessing good durability and reusability, thereby broadening application scenarios and reducing long-term usage costs.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] according to Figures 1 to 2 As shown in Example 1: Basic self-adhesive heat-insulating towel fabric.

[0023] This embodiment provides a basic and low-cost self-adhesive insulating terry cloth fabric suitable for wrapping and insulating general items. Fabric structure:

[0024] Towel fabric base material 1: Made of regular pure cotton towel fabric with a weight of 180-400g / m², it has full pile, good water absorption and soft touch.

[0025] Insulation layer 2: 1.0mm thick PE (polyethylene) closed-cell foam sheet. This material is lightweight, soft, does not easily absorb water, and has good thermal insulation and cushioning properties.

[0026] Self-adhesive layer 3: An acrylic pressure-sensitive adhesive (PSA) is used, and it is evenly coated on one side of the insulation layer 2 at a coating amount of 30g / m².

[0027] Manufacturing method:

[0028] Materials preparation: Prepare the above-mentioned pure cotton towel cloth, PE foam sheet and acrylic pressure-sensitive adhesive.

[0029] Composite process: Hot-pressing composite process is adopted. First, a layer of polyurethane (PU) hot melt adhesive is evenly sprayed onto the uncoated side of the PE foam sheet, with a coating amount of approximately 20g / m². Then, the bottom side (the side without lint) of the terry cloth substrate 1 is placed face to face with the PE foam sheet coated with PU adhesive.

[0030] Hot pressing: The stacked materials are fed into a hot press and hot pressing is carried out for 15 seconds at a temperature of 120°C and a pressure of 0.3MPa, so that the towel cloth substrate 1 and the PE foam insulation layer 2 are firmly bonded together.

[0031] Molding: After cooling, release paper (or anti-stick paper) is applied to the outside of the PE foam of the composite fabric roll (i.e. the outside of the item to be wrapped in the future), and then it is cut and rolled up to obtain the self-adhesive heat insulation towel fabric.

[0032] The advantages of this embodiment are: simple process, controllable cost, and the fabric produced has good heat insulation effect, convenient self-adhesion and soft protection of terry cloth, making it very suitable for wrapping water pipes, room temperature food boxes and other everyday items.

[0033] Example 2: High-performance self-adhesive thermal insulation terry cloth fabric and its manufacturing method

[0034] This embodiment provides a self-adhesive thermal insulation terry cloth fabric with superior thermal insulation performance, suitable for environments with higher requirements for temperature maintenance. Fabric structure:

[0035] Towel fabric base material 1: Made of microfiber towel fabric with a weight of 350g / m². This base material has finer fibers and a better feel.

[0036] Insulation layer 2: 2.0mm thick aluminum foil composite fiberglass wool. This material utilizes the high reflectivity of aluminum foil and the low thermal conductivity of fiberglass wool to effectively block heat radiation and heat conduction, significantly improving the insulation effect.

[0037] Self-adhesive layer 3: A rubber-based hot melt pressure-sensitive adhesive film with a thickness of 0.05 mm is selected.

[0038] Manufacturing method:

[0039] Materials preparation: Prepare the microfiber towel cloth, aluminum foil composite fiberglass cotton and rubber-based hot melt adhesive film mentioned above.

[0040] Stacking: A lamination process is used. The layers are stacked in the following order: "Towel fabric substrate 1 - Hot melt adhesive film - Aluminum foil composite fiberglass wool (fiberglass wool side facing the adhesive film)". The hot melt adhesive film serves as both the adhesive and the self-adhesive layer 3.

[0041] Hot-press lamination: The stacked materials are fed into a flat vulcanizing machine or a continuous laminator and hot-pressed for 20 seconds at a temperature of 150°C and a pressure of 0.5MPa. During this process, the hot melt adhesive film melts, firmly bonding the towel fabric substrate 1 to the aluminum foil composite fiberglass wool. After cooling, it also solidifies into a stable self-adhesive layer 3.

[0042] Post-processing: Similarly, release paper is applied to the surface of self-adhesive layer 3, and then the product is cut according to requirements to obtain the finished product.

[0043] Advantages of this embodiment: Excellent thermal insulation performance, especially suitable for scenarios requiring heat radiation reflection, such as automotive heat shields and temporary insulation wrapping for outdoor equipment. The self-adhesive layer 3 is film-like, preventing adhesive seepage and resulting in a clean appearance.

[0044] Example 3: Environmentally friendly and economical self-adhesive thermal insulation terry cloth fabric and its manufacturing method

[0045] This embodiment focuses on the environmental friendliness and cost-effectiveness of the materials, and is suitable for disposable or short-term use insulated wrapping scenarios. Fabric structure:

[0046] Towel fabric base material 1: Made of recycled polyester towel fabric with a weight of 250g / m², in line with environmental protection principles.

[0047] Insulation layer 2: Made of 0.8mm thick recycled PET (polyethylene terephthalate) nonwoven fabric. The pores formed by the multiple layers of PET fibers can effectively trap air, providing insulation, and the material is recyclable.

[0048] Self-adhesive layer 3: Water-soluble plant adhesive (such as modified starch adhesive) is selected and applied by dot coating. The coating covers an area of ​​about 60%, which not only ensures adhesion but also reduces the amount of adhesive used and facilitates subsequent degradation.

[0049] Manufacturing method:

[0050] Materials preparation: Prepare the above-mentioned recycled polyester terry cloth, recycled PET non-woven fabric and water-soluble plant glue.

[0051] Adhesive application and lamination: A spraying and cold-pressing lamination process is used. First, water-soluble plant-based adhesive is sprayed onto one side of the PET nonwoven fabric in a dot pattern using a spraying device. Then, the terry cloth substrate 1 is immediately bonded to the adhesive-coated surface.

[0052] Cold pressing curing: The laminated materials are passed through a pair of pressure rollers, and a pressure of 0.2 MPa is applied at room temperature to initially fix the two materials together. They are then placed in an drying tunnel and dried at a low temperature of 60°C for 5 minutes to cure the water-soluble adhesive and achieve a strong bond. At this point, the other side of the PET nonwoven fabric becomes the self-adhesive surface.

[0053] Rewinding: After covering the self-adhesive side with release paper, rewind. This fabric is easy to separate and dispose of after its service life, with minimal environmental impact.

[0054] The advantages of this embodiment are: extensive use of recycled materials, low cost, and environmental friendliness. It is suitable for scenarios such as fragile e-commerce parcels and supplementary insulation in short-distance cold chain transportation, meeting basic functional requirements while aligning with green and environmentally friendly trends.

[0143] Option A (this patent): Cost = 0.1 * X;

[0144] Option B (towel cloth + tape): Cost = 0.1 * 0.8X + 0.2X = 0.28X;

[0145] Option C (insulation cotton + tape): Cost = 0.1 * 0.6X + 0.2X = 0.26X;

[0146] Comprehensive cost analysis (considering operating hours, assuming the hourly cost of scheme A is Y);

[0147] Option A (this patent): Total cost = 1000 * 0.1X + 1.0Y (high efficiency, short working time);

[0148] Option B (towel cloth + tape): Total cost = 1000 * 0.28X + 2.5Y (low efficiency, long working hours);

[0149] Option C (insulation cotton + tape): Total cost = 1000 * 0.26X + 3.0Y (lowest efficiency, longest working time);

[0150] Key conclusions:

[0151] Material cost optimization: Although the unit fabric cost may be slightly higher due to the integrated design of this solution, it eliminates the cost of auxiliary materials (tape).

[0152] Significantly reduced overall costs: When considering labor efficiency, the total cost of this patent will be significantly lower than that of traditional combined solutions. This translates to substantial economic benefits in large-scale applications.
