Description

Multi-layer carpet Technical Field

[0001] The utility model relates to the technical field of detachable carpets, in particular to a multi-layer carpet. Background Art

[0002] Since its introduction, removable and washable two-in-one carpets have gained widespread popularity due to their washability, replaceability, and convenient storage. However, traditional methods for installing the carpet layer and anti-slip layer typically rely on traditional Velcro, singed non-woven fabric, or a combination of singed barbed and fleece knitted fabric. This has drawbacks during use, such as loud noise when ripping, prickly hooks that can easily damage clothing, dust collection, and damage to the suede, shortening its lifespan. Therefore, a textile fabric with excellent adhesion that doesn't rely on chemical adhesives is needed to replace traditional Velcro, singed non-woven fabric, and singed barbed fabric to improve the assembly and disassembly of two-in-one carpets, thereby enhancing the user experience and extending their lifespan.

[0034] Example 1

[0035] The carpet structure of this embodiment is shown in FIG1 , and the structures of the upper carpet 3 and the lower carpet 6 are shown in FIG2 and FIG3 respectively. A method for preparing a multi-layer carpet is provided, which specifically includes the following steps:

[0036] 1. Choose a 250GSM nylon BCF flat-cut tufted printed blanket with a pile height of 4mm and a 100GSM filament non-woven base fabric. Use EVA glue to secure the tufted and printed blanket.

[0037] 2. The solidified pile blanket surface and 150GSM non-woven fabric are flame-laminated together to form the first blanket surface layer 1. The purpose of laminating the non-woven fabric is to better maintain the appearance and size after washing.

[0038] 3. Polyester DTY150D / 36F (monofilament yarn approximately 4.17 DPF) is knitted on a single-needle-bar knitting machine. The fabric is then brushed, cut, dyed, and heat-blown to produce a silent monofilament bundle layer comprising monofilament bundles 7, or blanket backing layer 2. This layer has a grammage of approximately 200 grams per square meter, a pile length of approximately 2.5 mm, and a monofilament density of 174,960 strands per square inch. The silent monofilament bundle layer is then laminated with blanket surface layer 1 from step 2 to produce upper blanket 3.

[0039] 4. The 75D / 200F island-in-the-sea fiber and the 75D polyester high-elastic yarn are paralleled and stretched, and then weft-knitted (knitted) to obtain a weft-knitted ant cloth (i.e., knitted fabric). At 130°C, the fabric is degreased by alkali reduction (i.e., high-temperature dyeing and degreasing) with a 32% mass concentration NaOH solution and added to a dye vat to obtain a silent microfiber layer having a high-shrinkage fiber tow 8 and a microfiber tow 9, i.e., the second blanket surface layer 4, with a pile height (i.e., thickness) of 1.5 mm and a single-filament fineness of the microfiber tow 9 of 0.375D.

[0040] 5. Use PUR hot melt adhesive to compound the silent microfiber layer fabric prepared in step 4 with 700 g / m2 dot-molded non-woven fabric, i.e., the anti-slip layer 5, to obtain the lower blanket 6.

[0041] 6. Complete cutting, finishing, packaging and shipping.

[0042] Example 2

[0043] This embodiment provides a method for preparing a multi-layer blanket, which specifically includes the following steps:

[0044] 1. Choose 360GSM printed flannel as the blanket surface.

[0045] 2. A 500GSM printed flannel blanket surface and a 200GSM non-woven fabric are laminated together with PUR glue to form a first blanket surface layer 1 with a pile height of 5mm.

[0046] 3. 105D / 36F*37 polyester-nylon composite yarn and 100D high-shrinkage yarn are combined and tied with a heavy interlaced knot as the warp, and 150D / 14F polyester filament yarn is used as the weft to form a 180GSM warp microfiber fabric in a plain weave. This fabric is dyed and degreased at high temperature (130°C), then dried and shaped, and then subjected to high-speed fleece / sanding to produce a silent microfiber tow layer. The DPF of the microfiber tow 9 is approximately 0.08 DPF. This silent microfiber tow layer is then laminated with the first blanket surface layer 1 from step 2 to form the upper blanket layer.

[0047] 4. 1800D / 144F black polypropylene BCF yarn was used on a 1 / 12 gauge tufting machine to produce a cut-pile carpet with a row spacing of approximately 12.70 needles / inch and a pile height of 3.5 mm. 200gsm of stiffening agent (model TF-639B, ratio 30g / L) was sprayed on the carpet surface. The carpet was then placed in an oven for hot air treatment, causing the top ends of the BCF filament bundles 7 to bend and diverge, forming the second carpet surface layer 4. The filaments in the filament bundles 7 had a fineness of approximately 12.50 DPF and a density of approximately 21,946 strands per square inch.

[0048] 5. The back of the silent monofilament layer fabric is coated with 500GSM TPE anti-slip glue. During the coating, a hot air blower blows hot air to the blanket surface at a temperature of 120 degrees Celsius, further making the monofilaments on the blanket surface divergent and inclined, thereby obtaining the lower blanket of the present invention.

[0049] 6. Complete cutting, finishing and packaging.

[0050] Example 3

[0051] This embodiment provides a method for preparing a multi-layer blanket, which specifically includes the following steps:

[0052] 1. Select 700GSM jacquard fabric as the blanket surface, as the first blanket surface layer 1.

[0053] 2. Greige fabric was woven on a warp knitting machine using 215D / 36F*37 island-in-the-sea yarn (DTY) as the pile yarn and 150D / 72F polyester DTY as the base yarn. The fabric was then opened and degreased using 2g / L YZ-101 fiber opener and 6g / L 100% caustic soda at a bath ratio of 1:15. The opening temperature was controlled at approximately 95°C for 30 minutes. The fabric was then dyed, dried, and set, and finally high-speed brushed / fleshed to produce a silent microfiber tow layer. The microfiber tow 9 on the surface of the silent microfiber tow layer had a DPF of 0.16.

[0054] 3. The first blanket surface layer 1 in step 1 and the silent microfiber bundle layer in step 2 are combined to form the upper blanket 3 of the present invention.

[0055] 4. 1800D / 30F polyester BCF monofilament yarn and a 120GSM polyester imitation bonded nonwoven fabric were woven on a 1 / 6 tufting machine to create a blanket. The blanket was then sprayed with 300GSM of JISENNO electrostatic dust absorber (i.e., static enhancer), model 4957758, at a ratio of 30g / L. SBR adhesive was then applied to the back of the blanket and dried in a hot air oven to form the second blanket surface layer 4. The stitch count was approximately 10 stitches / inch, the pile height was 5mm, and the monofilament density was approximately 1800 strands / square inch. The drying and setting temperature was 160°C. After setting, the ends of the monofilament bundle 7 exhibited a slightly curved, diffuse shape.

[0056] 5. The fabric prepared in step 4 is compounded with 3D mesh cloth using PUR adhesive to obtain lower layer carpet 6. The back of the 3D mesh cloth is coated with 30GSM SEBS hot melt anti-slip adhesive.

[0057] 6. Complete cutting, finishing and packaging.

[0096] Experiment 2: Example 2 and Example 4 were quickly opened and closed, opened again, and closed again, and repeated 1000 times. The appearance of the four fabrics of the comparative example was observed and the durability was tested. The results are as follows:

[0105] Example 3 = almost no change;

[0106] Example 5 = Almost no change.

[0107] In summary, it can be seen that under the filament fineness and filament density of the silent monofilament bundle layer of the present invention, the obtained multi-layer carpet has excellent horizontal bonding tension, durability and economic value. In addition, stiffeners are usually used on flat fabrics to make the fabric more stiff. The present invention creatively uses stiffeners to add a small amount of stiffeners in the processing steps of the silent monofilament bundle layer, and unexpectedly finds that the horizontal bonding tension of the carpet can be improved, the use scenarios of the carpet can be expanded, and the durability of the carpet can be enhanced. At the same time, the present invention creatively adds a small amount of electrostatic enhancer (electrostatic dust absorber) in the processing steps of the silent monofilament bundle layer to further enhance the horizontal bonding tension of the upper and lower carpets. More importantly, unlike the hook-and-hook bonding of the traditional loop and hook structure, the surface of the silent microfiber layer of the present invention is distributed with microfiber bundles, which easily generate a strong electrostatic adsorption effect under the action of gravity and external force. After bonding with the silent monofilament bundle layer, it has a strong horizontal bonding tension, achieves a strong bonding effect, and has higher durability.
