Problems solved by technology

However, this recycling method requires the use of equipment such as cutting, melting, granulating, and molding. These high-power equipment consume a lot of energy, and high-frequency operations also consume a lot of manpower. In the process of cutting fibers, a large amount of The dander and dust will further cause physical damage to the operators, and the secondary pollution and large consumption of energy will have an irreversible impact on the environment.

Embodiment 1

[0051] Embodiment 1: the above-mentioned method for manufacturing the soft bottom carpet that utilizes recycled yarns to prepare may further comprise the steps:

[0052] (1) Carpet fiber tufting

[0053] Nylon fibers are tufted on the first long-fiber non-woven fabric by tufting carpet weaving machine equipment to form a carpet fiber layer, and rolled into rolls for later use. The piled side of the carpet fiber layer is the carpet pile, and the other side is the tufted back, which is to be pre-coated with latex.

[0054] (2) Latex pre-coating and drying

[0055] Water-based environmentally friendly latex SBR is used, and the ratio is SBR: antibacterial agent: calcium carbonate: foaming agent = 62-100: 0-1:0-35: 0-2, preferably 65-70: 0-1: 28-35: 0 to 1, wherein the content of antibacterial agent and foaming agent can be 0, put the above raw materials into the mixing tank according to the proportion, after stirring evenly, use a foaming machine to carry out air foaming, the f...

Embodiment 2

[0064] Embodiment 2: Resilience ratio of wheelchair experiment

[0065] The size of the finished square blanket is 500mm*500mm, and the thickness of the sample is measured with a thickness gauge, and the valid data is recorded. Place the measured carpet on the bottom plate of the wheelchair tester to fix it, place the simulated wheelchair foot with a load of 90kg on the carpet surface, set the number of rotations to 2000 revolutions, and start the instrument. After the rotation, take out the sample blanket and place it horizontally for 24 hours. After the above steps are completed, use the thickness gauge again to measure the full thickness of the sample to obtain valid data. Calculate the resilience ratio after comparing the valid data.

[0066] The soft-bottom carpet of recycled yarn and the recycled yarn soft-bottom carpet without non-essential structure are manufactured with reference to the method of embodiment 1.

[0067] Conclusion: The higher the percentage, the hig...

Abstract

The invention discloses a soft-bottom carpet prepared from recycled yarns, and belongs to the technical field of carpet manufacturing. The carpet sequentially comprises a carpet fiber layer and a recycled fiber layer from top to bottom, the carpet fiber layer comprises carpet fibers and a first long-fiber non-woven fabric, the carpet fibers are tufted on the first long-fiber non-woven fabric, therecycled fiber layer comprises recycled fibers and a second long-fiber non-woven fabric, and the recycled fibers are tufted on the second long-fiber non-woven fabric. And the carpet fiber layer and the recycled fiber layer are fixedly bonded. The soft-bottom carpet has the advantages of being soft in material, high in comfort level, good in elasticity, stable in physical property, good in heat insulation effect and the like.

Description

technical field [0001] The invention belongs to the technical field of carpet manufacture, and in particular relates to a soft-bottomed carpet prepared from recycled yarns and a manufacturing method thereof. Background technique [0002] At present, most domestic carpets use PVC or asphalt as the substrate after the carpet surface is tufted, and a glass fiber layer can be added in the middle to improve the dimensional stability of the carpet, or a non-woven substrate can be attached after the carpet surface is tufted. . However, PVC substrates are used on carpets, usually with hard texture and poor comfort. Major manufacturers have been trying to find a new material to replace PVC as carpet substrates; and non-woven substrates , although compared with PVC material, it is relatively soft, but due to its dimensional instability and physical properties that are easy to warp, the quality disadvantages continue to appear during use. Therefore, we have been committed to creating...
