A polyester fiber terry cloth with a braided structure

Abstract

This utility model discloses a polyester fiber terry cloth with a braided chain structure, including a terry cloth body made of polyester fiber material with loops, and a binding fabric around the terry cloth body. The binding fabric has continuous inner wavy braids and continuous outer wavy braids extending out of the binding fabric. The top of each wave unit of the inner wavy braid is connected to the bottom of each wave unit of the outer wavy braid, and the connection is located at the outer edge of the binding fabric. The outer wavy braid and the outer edge of the binding fabric form a spaced hanging hole structure. The entire polyester fiber terry cloth has a hanging hole structure around its entire perimeter, which can hang the terry cloth at any position on the perimeter, making it more convenient to use without the need to prepare an additional hanging rope structure. Since the outer wavy braid is connected to the inner wavy braid, and the inner wavy braid passes through the binding fabric and the terry cloth body and is woven continuously, the sturdiness of the hanging structure is ensured.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0032] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.

Therefore, they should not be construed as limitations on this utility model.

[0034] like Figure 1-4 As shown, this embodiment provides a polyester fiber terry cloth with a woven chain structure, including a terry cloth body 1 made of polyester fiber with loops, and a binding fabric 2 around the perimeter of the terry cloth body 1. The binding fabric 2 has continuous inner wavy braided chains 3 and continuous outer wavy braided chains 4 extending beyond the binding fabric 2. That is, the binding fabric 2 integrates two continuous lace-like edges, namely the "inner wavy braided chains 3" and the "outer wavy braided chains 4". The binding fabric 2, the inner wavy braided chains 3, and the outer wavy braided chains 4 not only seal the outer perimeter of the polyester fiber terry cloth, but also make the polyester fiber terry cloth more aesthetically pleasing.

[0035] like Figure 3-4As shown, the top 31 of each wave unit of the inner wavy braided chain 3 connects to the bottom 41 of each wave unit of the outer wavy braided chain 4, and the connection point 5 is located at the outer edge of the binding fabric 2. A spaced hanging hole structure 6 is formed between the outer wavy braided chain 4 and the outer edge of the binding fabric 2. Because the spaced hanging hole structure 6 is formed between the outer wavy braided chain 4 and the outer edge 21 of the binding fabric 2, the entire polyester fiber terry cloth has hanging hole structures 6 on all four sides. Therefore, the terry cloth can be hung at any position on its outer periphery, making it more convenient to use without the need for additional hanging rope structures. Furthermore, since the outer wavy braided chain 4 is connected to the inner wavy braided chain 3, and the inner wavy braided chain 3 is woven through the binding fabric 2 and the terry cloth body 1 continuously, even if a single wave unit of the outer wavy braided chain 4 is pulled forcefully, it will not come undone, thus ensuring the stability of the hanging structure.

[0036] Furthermore, the inner wavy braided chain 3 has a multi-strand braided winding structure 31 on one side of the terry cloth and a single-strand plain knit structure 32 on the other side. Therefore, users can clearly determine the front and back of the terry cloth through the structure of the inner wavy braided chain 3. In addition, it also creates a three-dimensional tactile feel, allowing users to distinguish the front and back by touch alone, and thus select the appropriate side according to their needs when using it.

[0037] Preferably, the inner wavy braid 3 and the outer wavy braid 4 are formed by continuous loops connected in series. In terms of weaving technology, the inner wavy braid 3 and the outer wavy braid 4 are woven using a lock-stitch technique. The inner wavy braid 3 is a single-row braid structure, interwoven with the terry cloth body 1 using a lock-stitch technique. The outer wavy braid 4 is a double-row braid structure, suspended at the outer edge.

[0038] Preferably, the width of the outer wavy braid 4 is greater than that of the inner wavy braid 3, and the wave height of the outer wavy braid 4 is 3~8mm.

[0039] like Figure 3-4 As shown, the inner wavy braid 3 and / or the outer wavy braid 4 are made of color-changing yarn, which is prepared by dyeing with pH-sensitive dyes and redox dyes. The dyes need to be loaded onto the yarn fibers through microencapsulation or covalent fixation technology. Different stains will cause the inner wavy braid 3 and the outer wavy braid 4, which use color-changing yarn, to change color, thus establishing a stain identification system.

[0040] Stains on the terry cloth body 1 will seep into the binding fabric 2. The inner wavy braided chain 3 is entirely located within the binding fabric 2, so the stain will first spread to the inner wavy braided chain 3, and then slowly spread and seep into the outer wavy braided chain 4 as the inner wavy braided chain 3's weave structure progresses. Therefore, the cleanliness of the polyester fiber terry cloth can be judged by comprehensively observing the extent of discoloration in both the inner and outer wavy braided chains 3 and 4. This braided chain structure provides a gradual indication, which is far more effective than using the entire binding fabric to indicate stains.

[0041] pH-sensitive dyes include bromocresol purple and phenolphthalein. They can be selected based on the application scenario of a woven terry cloth. Under different pH conditions, the wavy weave will change color, thus indicating the pH characteristics of the fabric. Furthermore, the color-changing ability of the yarn decreases significantly after multiple washes, therefore it can be used to assess the number of washes.

[0042] Redox dyes include methylene blue redox dyes and indigo redox dyes. These color-changing yarns are sensitive to oil stains and can reflect the effects of oil contamination on polyester terry cloth. One redox dye can be a combination of methylene blue and indigo, where methylene blue responds quickly to reducing oil stains and indigo responds to solvent-based oil stains. Alternatively, a combination of methylene blue and fluorescent dyes can be used, where oil stains cause fluorescence quenching.

[0043] Preferably, the inner wavy braid 3 and the outer wavy braid 4 are different colors, further enhancing the aesthetics of the polyester fiber terry cloth. This also allows the inner wavy braid 3 and the outer wavy braid 4 to use different color-changing yarns. Specifically, the inner wavy braid 3 uses a redox dye primarily for responding to oil stains, while the outer wavy braid 4 uses a pH-sensitive dye to further assess the level of contamination through pH. This is because grease or organic solvents may affect the pH diffusion rate, leading to a delayed color change. Using a redox dye on the inner wavy braid 3 allows for an initial response to oil stains to assess the cleanliness of the polyester fiber terry cloth. The outer wavy braid 4 itself is a later-responding region, so even if grease or organic solvents affect pH diffusion, it will not cause the entire contamination detection system to fail.

[0044] Based on the capillary gradient diffusion of stains from the loop fabric to the binding fabric 2, then to the inner wavy braid 3, and finally to the outer wavy braid 4. In cases of light oil stains, only the inner wavy braid 3 shows localized discoloration. As the oil stain increases and water-soluble stains appear, the area of ​​the inner wavy braid 3 expands, and the outer wavy braid 4 subsequently develops color. In cases of heavy stains, the colors of the inner wavy braid 3 and the outer wavy braid 4 overlap, allowing for visual judgment of when to clean. This cascaded color development logic of "oil first, then pH" improves the accuracy compared to dyeing the entire binding fabric and avoids misjudgments caused by oil blocking pH dyes.

[0045] like Figure 2 As shown, at least one corner of the terry cloth body 1 is provided with a main hanging rope structure 7, which is formed by extending from the binding fabric 2 and folding it back and fixing it; the inner wavy braided chain 3 and the outer wavy braided chain 4 extend to the main hanging rope structure to meet the requirements of high-strength suspension; the inner and outer wavy coils also extend to the root of the hanging rope to ensure visual continuity and structural uniformity.

[0046] Regarding the material selection for the binding fabric 2, non-woven fabric is preferred. The binding fabric 2 is heat-pressed and bonded to the terry cloth body 1, making the processing more convenient. Alternatively, polyester-cotton fabric can also be used for the binding fabric 2. Besides the two braided structures, "inner wavy braided chain 3" and "outer wavy braided chain 4," the binding fabric 2 requires no other form of fixation.

[0047] Preferably, the terry cloth body is made of a double-sided looped structure woven from a blend of 30% nylon and 70% polyester yarn. Compared with existing polyester-nylon terry cloths with looped structure, this improves abrasion resistance, while the 30% nylon content further improves water absorption, thereby enhancing the user's car washing and wiping experience.

[0048] This invention describes a polyester fiber terry cloth with a braided structure. Specific examples are used to illustrate the principle and implementation of this invention. The descriptions of these embodiments are merely for the purpose of helping to understand this invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this invention.
