Description

Technical Field

[0001] This utility model relates to the field of color-absorbing sheets, and more specifically, it relates to a color-absorbing sheet for composite laundry detergent pods. Background Technology

[0002] In the laundry industry, color-absorbing sheets are a commonly used auxiliary washing accessory. Their core is made of non-woven fabric substrate, and active adsorption ingredients (such as cationic adsorbents, polymer chelating agents, etc.) are usually added inside. They can adsorb free dye molecules in the water during the washing process, effectively preventing color bleeding and mixing of clothes. They are especially suitable for washing multi-colored clothes in the same machine, ensuring the color vibrancy and cleanliness of the clothes. Most color-absorbing sheets on the market are single-layer or simple double-layer non-woven fabric structures, which need to be removed and placed separately during use, and have the following technical defects: First, the structure is fixed and the area used at one time cannot be adjusted, which can easily lead to material waste when washing a small amount of clothes, and insufficient absorption capacity when washing a large amount of clothes; Second, there is a lack of synergistic design with detergent (such as laundry detergent pods). Laundry detergent pods need to be added separately, which is not only cumbersome, but also prone to damage to the outer film due to the rolling and collision of laundry detergent pods in the washing tub, resulting in premature release of liquid and uneven concentration, which affects the washing effect. To address the aforementioned operational inconveniences, some products have attempted to combine color-absorbing sheets with laundry detergent pods. However, existing composite structures still have significant shortcomings: either they use a simple stacking method to place the laundry detergent pods on the surface of the color-absorbing sheet, causing the pods to easily fall off or shift; or they use adhesives to fix the laundry detergent pods to the color-absorbing sheet, and adhesive residues may not only affect the adsorption performance of the color-absorbing sheet but may also be difficult to completely dissolve in water, posing environmental risks and failing to fully leverage the synergistic effect of washing and color protection. Therefore, there is an urgent need to design a composite laundry pod color-absorbing sheet that combines color absorption and laundry pod carrying functions, has an adjustable structure, is easy to use, and is environmentally friendly, in order to make up for the shortcomings of existing technologies. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a color-absorbing sheet for composite laundry detergent pods.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a color-absorbing sheet for a composite laundry detergent pod, comprising two non-woven fabric layers, wherein a folded and bent portion is formed between the two non-woven fabric layers by a hot-pressing composite process, the folded and bent portion separating the double-layer non-woven fabric layers into two relatively independent and foldable stackable sides. After the two nonwoven fabric layers are separated, the three sides of each side that are not heat-pressed are fixed by sewing with water-soluble fiber thread, so that the two sides form closed internal spaces respectively. Laundry detergent pods are placed inside the internal space, and positioning devices are provided in the internal space. The laundry detergent pods are distributed in an array through the positioning devices. A row of easy-tear grooves is stamped on the folded and bent part. By tearing open the row of easy-tear grooves, the overall amount of color-absorbing sheet composed of non-woven fabric layers and the amount of laundry detergent pods inside can be adjusted.

[0005] The present invention is further configured such that: the positioning element is a cross-shaped water-soluble suture, which is fixedly connected to the two layers of non-woven fabric, and a receiving cavity is formed between adjacent cross-shaped water-soluble sutures, and the laundry detergent beads are received one by one into the receiving cavity to achieve an array distribution.

[0006] The present invention is further configured such that: the water-soluble fiber thread is a polyvinyl alcohol fiber thread, the complete dissolution condition is a water temperature of 20-40℃, and the tensile strength is not less than 3cN / dtex, and the stitch spacing of the polyvinyl alcohol fiber thread is 2-3mm.

[0007] The present invention is further configured such that the laundry detergent pods are spherical in shape, with a diameter of 3-8 mm, and are composed of a water-soluble film encapsulating laundry essence.

[0008] The present invention is further configured such that: the two nonwoven fabric layers are separated by a folded and bent portion, and the two sides are an inward folded structure; the water-soluble fiber thread is used to sew and fix the overlapping edge formed by the inward folding of the nonwoven fabric layer; when the water-soluble fiber thread dissolves in water, the nonwoven fabric layer can be unfolded outward along the overlapping edge, and the area of ​​a single nonwoven fabric layer after unfolding is 1.5-2 times that in the folded state.

[0009] The present invention is further configured such that: a plurality of viscose fibers are provided on the nonwoven fabric layer.

[0010] In summary, this utility model has the following beneficial effects: it integrates the color-absorbing sheet and laundry detergent pods, eliminating the need for separate handling and solving the problem of cumbersome operation in traditional products. It is also flexible and adjustable; the easy-tear groove on the folded and bent part allows for adjustment of the amount of color-absorbing sheet and laundry pods as needed. The inner fold structure, when unfolded, can increase the adsorption area, adapting to the washing needs of different garments. It uses water-soluble materials such as polyvinyl alcohol fiber threads, leaving no adhesive residue and completely dissolving during washing. The structure is stable and reliable, with strong fiber thread stitching, preventing the laundry pods from falling off or breaking during transportation or storage. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0014] A color-absorbing sheet for a composite laundry detergent pod, such as Figure 1 , Figure 2 and Figure 3 As shown, the product includes two non-woven fabric layers 1. Cationic adsorbents and polymeric chelating agents are pre-added to the non-woven fabric layers 1. Simultaneously, several viscose fibers are laid on the surface of each non-woven fabric layer 1. The viscose fibers are fixed to the non-woven fabric layers 1 by hot pressing. The viscose fibers have good toughness, making them less prone to breakage and shedding during washing, thus improving the toughness and strength of the non-woven fabric layers 1. Next, the two non-woven fabric layers 1 are processed by forming a folded section 2 in the middle of the two layers through a hot-pressing composite process. This folded section 2 separates the two layers into relatively independent left and right sides, and both sides can be folded and stacked along the folded section 2, reducing storage space. Simultaneously, a row of easy-tear grooves 5 is stamped on the folded section 2, with a spacing of 1cm, allowing the color-absorbing sheets of the composite laundry pods to be torn apart for separate use, facilitating users to adjust the amount used according to the amount of clothing. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the two-sided structure after separation on the color-absorbing sheet of the composite laundry detergent pod, the non-woven fabric layer 1 on both the left and right sides is treated by inward folding, so that the outer side of each side is an overlapping edge 7. Then, water-soluble fiber thread 3 (specifically polyvinyl alcohol fiber thread) is used to sew and fix the three sides of each side that are not heat-pressed and laminated. The sewing process adopts a flat sewing technique with a stitch distance controlled at 2.5mm. The polyvinyl alcohol fiber thread can be completely dissolved at a water temperature of 25℃ and has a tensile strength of 3.2cN / dtex. This can not only ensure that a closed internal space is formed after sewing to prevent the laundry detergent pod 4 placed later from falling off, but also avoid the environmental hazards of adhesive residue, thus solving the problem of poor environmental protection of existing composite structures. like Figure 1 , Figure 2 and Figure 3As shown, before placing laundry pods 4 in the internal space, a cross-shaped water-soluble suture 6 is first sewn in each internal space using polyvinyl alcohol fiber thread. The spacing between the intersections of the cross-shaped sutures is set to 10mm, and a square receiving cavity is formed between adjacent cross-shaped sutures. Then, laundry pods 4 are placed into the receiving cavity one by one, and then the next cross-shaped water-soluble suture 6 is sewn, and then laundry pods 4 are placed in. This process is repeated to complete the positioning and placement of laundry pods 4. The laundry pods 4 are spherical structures with a diameter of 5mm, made of laundry essence wrapped in a water-soluble film. The essence contains 22wt% surfactant, 1.2wt% enzyme preparation, 3wt% color protectant and the remainder deionized water. Several laundry pods 4 are placed in each internal space. The receiving cavity formed by the cross-shaped sutures can accurately fix the pods and achieve an array distribution, avoiding displacement or collision of the pods during transportation or washing, which can lead to damage. This solves the problems of easy breakage and uneven concentration of pods in existing products, and can also maintain the uniformity of the color-absorbing sheet of the composite laundry pod after folding. When using the washing machine, if washing a small amount of clothes, simply place the absorbent sheet directly into the washing machine. At this time, the absorbent sheet is folded, the internal space is sealed, and the laundry pods 4 are stably placed. If washing a large amount of clothes, an additional absorbent sheet can be added on top of the original amount. Tear off a portion along the easy-tear groove 5 of the folded section 2 to adjust the overall amount of absorbent sheet used and the amount of laundry pods added, avoiding material waste or insufficient absorption. After the washing machine is filled with water, the water temperature reaches 25℃. The polyvinyl alcohol fiber threads (including water-soluble fiber threads 3 and cross-shaped water-soluble stitching 6) gradually dissolve, the internal space opens, the water-soluble film dissolves simultaneously, and the laundry essence is released evenly. As the fiber threads completely dissolve, the non-woven fabric layer 1 unfolds outward along the overlapping edge 7. After unfolding, the area of ​​a single non-woven fabric layer 1 is 1.8 times that in the folded state, increasing the adsorption area. At the same time, the viscose fiber works synergistically with the original adsorption components to efficiently adsorb free dye molecules in the water, preventing color bleeding of clothes. The entire process does not require separate removal and placement of color-absorbing sheets and laundry detergent pods, making it convenient to operate. All water-soluble materials are completely dissolved without residue, taking into account practicality, environmental protection, and washing and color protection effects. It comprehensively solves the technical problems existing in the background technology, such as fixed structure, poor synergy, and environmental hazards.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
