Description

Technical Field

[0001] This invention relates to the field of children's educational shaping toys, specifically to a children's educational shaping wax rope. Background Technology

[0002] Traditional hand-woven bracelets and ropes are mostly made from ordinary cotton thread, wool, or synthetic fibers. These threads tend to spring back after bending, making assembly difficult and shaping challenging. This makes them unsuitable for children's creative DIY projects, letter and pattern building, which require repeated bending, free combination, and arbitrary shaping. While modeling clay is malleable and easy to assemble, it is sticky, prone to color bleeding, easily clumps together, cracks after drying, cannot be restored to its original shape, has poor temperature adaptability (its hardness changes significantly with temperature), and cannot be easily moved after shaping. It also struggles to form stable linear structures, thus failing to meet the needs of children's creative sculpting.

[0003] To address the aforementioned issues, there is a need for a children's educational shaping product that combines the flexibility, malleability, and shape retention of the wire, allowing it to be repeatedly bent, freely assembled, and reused, while also providing good safety and comfort. Summary of the Invention

[0004] The purpose of this invention is to provide a malleable waxed rope for children's educational purposes, in order to solve the problems of insufficient shaping ability, poor shape retention, easy rebound after repeated bending, and insufficient stable shaping effect of traditional hand-woven hand ropes and similar products.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A type of malleable waxed rope for children's educational purposes, comprising a fiber core and a wax coating;

[0007] The fiber core is an acrylic yarn core. In the overall weight of the waxed rope, the fiber core accounts for 10% of the total weight, and the wax coating accounts for 90% of the total weight. The fiber core is a multi-strand twisted composite core mainly composed of acrylic fibers. By weight percentage, it is made of 75%-85% acrylic short fibers, 10%-15% high-twist polyester filaments, and 5%-15% degummed flax long fibers, with a porosity of 15%-25%, a twist of 60-100 twists / meter, and a surface roughness Ra of 3.2μm-6.3μm.

[0008] The wax coating is a wax layer formed with imported microcrystalline wax, which has a melting point of 60℃-72℃.

[0009] The wax coating fills the internal pores of the fiber core and covers the outer surface of the core, forming a solid cylindrical shape. The diameter of a single finished wire is 1.0mm-3.0mm, the Shore A hardness of the wax layer is 20-35, the room temperature bending resilience is ≤8%, and the peel strength between the wax layer and the core is ≥0.2N / mm.

[0010] Furthermore, the acrylic staple fiber has a fineness of 1.5D-3.0D and a length of 38mm-51mm; the high-twist polyester filament has a fineness of 15D-30D and a single filament twist of ≥200 twists / meter; and the degummed flax filament has a length of 40mm-55mm and a residual glue rate of ≤2%.

[0011] Furthermore, the raw material for the wax coating is imported microcrystalline wax.

[0012] Furthermore, the wax coating has a filling rate of ≥90% for the internal pores of the core wire, a wax layer thickness of 0.15mm-0.60mm on the outer surface of the core wire, and a surface friction coefficient of 0.35-0.55.

[0013] Furthermore, the fiber core is made of 3 or 5 strands twisted in the Z direction, with a strand gap ratio of ≤5% and a tensile breaking strength of ≥1.5cN / dtex.

[0014] Furthermore, the content of migratable heavy metals in the waxed rope meets the GB6675.4-2025 standard, the skin irritation reaction score is ≤0.5, and the biodegradation rate after 180 days is ≥30%.

[0015] Furthermore, the waxed rope does not stick or crack in an environment of -5℃ to 45℃, and the wax layer peeling rate is ≤2% after 1000 cycles of reciprocating friction.

[0016] A method for preparing a malleable wax rope for children's educational purposes includes the following steps:

[0017] S1. Acrylic staple fiber, high-twist polyester filament and degummed flax filament are opened, combed and drawn in proportion and then twisted in the Z direction. The twist is controlled at 60-100 twists / meter and then the surface is roughened to obtain composite core yarn.

[0018] S2. Heat the imported microcrystalline wax to 80℃-90℃ to melt it, and stir it at a constant temperature for 20-40 minutes to obtain the wax liquid.

[0019] S3. Impregnate the composite core wire with wax liquid at a speed of 5-10m / min for 3-10s, and keep the wax liquid temperature at 80℃-90℃.

[0020] S4. After being impregnated with wax, the rope is cooled and shaped at 18℃-28℃ for 5-15 seconds. After surface polishing, it is rolled up to obtain the finished product. It is then cut as needed, with the standard cut length of a single finished product being 15.2cm-30cm.

[0021] Compared with existing technologies, the present invention provides a children's educational and malleable wax rope, which uses long rolls of acrylic yarn as the base material and is integrally formed by multiple impregnation and bonding processes using molten imported microcrystalline wax. Through the combination of acrylic, polyester, and linen composite core yarn and microcrystalline wax impregnation and coating structure, the wax rope has a soft feel, good temperature adaptability, stable shaping and retention, and elastic recovery. It can be freely bent, folded, glued, and assembled into any shape, letter, pattern, and three-dimensional model. It can exercise children's hands-on ability, thinking ability, and hand-eye-brain coordination, stimulate children's imagination and creativity, and has good shaping retention, reusability, and safety. It is suitable for children's educational shaping creation and creative DIY activities. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 4As shown, the present invention provides a children's educational and malleable wax rope, comprising a fiber core 1 and a wax coating 2. The fiber core 1 is an acrylic yarn core, and the fiber core accounts for 10% of the total weight of the wax rope, while the wax coating accounts for 90%. The fiber core is made of acrylic, polyester, and linen composite twisted together to form a hollow mesh structure. The wax coating is formed using imported microcrystalline wax, and the internal pores of the core are filled and the outer surface of the core are covered by an impregnation process, so that the wax rope has softness, surface adhesion, shape retention, and repeated bending recovery. After the wax coating is cured, its outer surface retains a certain degree of adhesion. When two sections of wax rope come into contact with each other, overlap, or stick together, the contact area can produce an adhesive effect, so that the two sections of wax rope are relatively fixed, thus completing the combination connection between wax ropes without the need for additional glue, connecting buckles, or other connecting parts.

[0059] Example 4

[0060] This embodiment is a larger-sized, malleable wax rope for children's educational purposes. The finished rope body has a diameter of 3.0mm and is suitable for children's three-dimensional modeling, large-sized pattern assembly, educational model building, and creative DIY activities that require high rope support and shaping retention.

[0061] Raw material selection: Acrylic staple fiber, high-twist polyester filament and degummed flax filament are selected as composite core yarn raw materials. The acrylic staple fiber, polyester filament and flax filament are formulated in a weight ratio of 75:10:15 to increase the proportion of flax fiber in the composite core yarn.

[0062] Raw material pretreatment: The three types of fibers are weighed and mixed in a weight ratio of 75:10:15, and then opened, combed and drawn to make the different fibers evenly dispersed.

[0063] Composite core preparation: The mixed fibers are twisted in the Z direction to prepare composite core, with the twist controlled at 60-100 twists / meter. The core surface is roughened to give it fiber gaps and surface structure suitable for the penetration and bonding of the wax coating.

[0064] Wax preparation: Imported microcrystalline wax is used as the raw material for wax coating. It is heated to 80℃-90℃ to fully melt it, and stirred at a constant temperature for 20-40 minutes to form a uniform wax liquid.

[0065] Impregnation and coating: The prepared composite core wire is impregnated with wax liquid at a speed of 5-10 m / min, so that the molten microcrystalline wax enters the internal pores of the core wire and coats the outer surface of the core wire. By controlling the impregnation time and wax liquid temperature, the diameter of the finished product reaches 3.0 mm.

[0066] Cooling and shaping: The waxed rope is cooled and shaped in an environment of 18℃-28℃ after being impregnated, so that the wax coating changes from a molten state to a stable solid state, and the surface is polished to remove excess wax.

[0067] Performance testing: The 3.0mm larger specification waxed rope prepared in this embodiment has a room temperature bending rebound rate of about 5% and has good bending shape retention ability under the specified test conditions. Due to the use of a high proportion of degummed flax long fibers in the core, the finished product has good biodegradability, with a biodegradability rate of 45% after 180 days.

[0068] The data is shown in the table below:

[0069] Example 1 2.3mm Standard Model 80:12:8 Rebound rate 4%, friction shedding rate 1.2% Example 2 1.5mm fine specification 75:15:10 Rebound rate 7%, friction shedding rate 1.8% Example 3 2.0mm Medium Size 78:14:8 Rebound rate 6%, friction shedding rate 1.5% Example 4 3.0mm Larger Size 75:10:15 Rebound rate 5%, degradation rate 45%

[0070] This waxed rope uses a hollow mesh core structure formed by the composite twisting of acrylic, polyester, and flax fibers. Combined with an imported microcrystalline wax impregnation and coating process, the wax layer evenly penetrates and coats the inside and outside of the core, ensuring a stable bond between the wax layer and the core that is not easily detached. The waxed rope has moderate surface tack at room temperature, is not easily adhered to children's skin, has no obvious odor, and has a delicate and smooth touch. When in use, it can be freely bent and folded. The waxed ropes that come into contact with each other can be bonded and fixed using their own surface tack, eliminating the need for additional glue or connectors to complete the pasting and assembly, and forming a stable linear structure.

[0071] This waxed rope can be made in different colors according to actual needs. By adjusting the color of the wax coating, products in red, yellow, blue, green, orange, purple and other colors can be formed, thereby meeting children's needs for different color matching, pattern assembly and three-dimensional model creation, making the product have a variety of color choices, and not limited to a single color.

[0072] This wax rope uses readily available raw materials and has a simple preparation process, enabling large-scale production. It is suitable for applications such as children's educational shaping toys, creative DIY materials, and line drawing creation.

[0073] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
