Description

Technical Field

[0001] This utility model relates to fabric structure, and more particularly to an anti-wrinkle fabric structure. Background Technology

[0002] In the textile manufacturing industry, the shape retention of fabrics is a key selling point, and wrinkle resistance is one of the most important properties of shape retention. Whether it's high-end clothing, shoe uppers, or home textiles, both manufacturers and consumers want fabrics to remain smooth and crisp after wear and use, requiring minimal ironing.

[0003] There are two main manufacturing methods for wrinkle-resistant fabrics on the market: Adding anti-wrinkle resins, such as formaldehyde-containing N-hydroxymethyl resins, cross-links with the fiber molecular chains to enhance the fiber's elastic recovery. While this method is relatively effective, the chemical auxiliaries may cause skin allergies in consumers, and there is a risk of excessive formaldehyde release. The anti-wrinkle effect significantly diminishes after multiple washes. Chemical cross-linking damages the natural softness of the fabric fibers, resulting in a stiff feel, poor breathability, and reduced wearing comfort.

[0004] Increasing the density of warp and weft yarns or using high-count yarns can make the fabric structure more compact, but such fabrics become very thick, stiff, have poor breathability, lose elasticity, and are difficult to recover once wrinkles form.

[0005] Spandex can be wrapped around the weft yarns, or high-elastic polyester filaments can be used. Compared to high density and high count, the fabric has a certain degree of elastic recovery, but not only is spandex expensive, but such a fabric structure also lacks a sense of structure and is difficult to meet the requirement of crispness. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides an anti-wrinkle fabric structure.

[0007] To solve the above technical problems, the technical solution adopted by this utility model is: an anti-wrinkle fabric structure, including warp yarns and weft yarns woven together. The warp yarns include multiple warp units. Each warp unit is formed by the cross-twisting of the first warp yarn and the second warp yarn to form several twist knots and weft yarn channels are formed between adjacent twist knots. The twist knots and weft yarn channels are arranged alternately along the length of the warp yarns to form a twisted structure.

[0008] The weft yarn is woven into a braid by twisting together multiple weft threads.

[0009] Furthermore, the warp yarns include corrugated warp yarns and support warp yarns arranged periodically, with each unit centimeter containing 3 to 5 periodic units.

[0010] Furthermore, each set of periodic units includes three corrugated warp yarns 11 and one support warp yarn 12, with three corrugated warp yarns 11 arranged on the other side of the support warp yarn 12 in a mirror image of the three corrugated warp yarns 11.

[0011] Furthermore, the path of the corrugated warp extends in a sinusoidal wave shape, the elongation of the supporting warp is ≤5%, and the corrugated structure of the corrugated warp gives the fabric lateral elastic recovery force.

[0012] The support warp extends in a straight line, with an elongation of 8–15%, and provides longitudinal rigid support.

[0013] Furthermore, the first warp 14 is a thermoplastic synthetic fiber filament, and the second warp is a synthetic fiber profiled filament.

[0014] Furthermore, the twist of the braid is 200–500 twists / meter.

[0015] Furthermore, the axial spacing of the twisted knots is 0.5–2 mm, and the width of the weft channel is 0.3–1 mm.

[0016] Furthermore, the ratio of the diameter of the braid to the width of the weft channel is 1:1.2–1:1.8.

[0017] A wrinkle-resistant fabric structure replaces traditional chemical resin cross-linking with a physical interlocking structure of warp yarn twist knots and weft yarn braids, eliminating the risk of formaldehyde release at the source. The corrugated warp yarns support the fabric's lateral elastic recovery ability, while the supporting warp yarns provide longitudinal rigid support. The periodic arrangement of the two forms a wrinkle-resistant fabric skeleton with dynamic cushioning. At the same time, the combination of the braids and the weft yarn channels allows the weft yarns to slide slightly when subjected to external forces, but there is no displacement after washing, making the fabric wrinkle-resistant, breathable, and environmentally friendly.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-3 As shown in the figure, this embodiment of the anti-wrinkle fabric structure includes interwoven warp yarns 1 and weft yarns 2, as follows: Figure 1 As shown, the warp 1 includes multiple warp units, each of which is formed by the cross-twisting of the first warp 14 and the second warp 15. In terms of material selection, the first warp 14 in this embodiment is made of thermoplastic synthetic fiber filament, preferably PET material, and the second warp 15 is made of synthetic fiber profiled filament, preferably PTT material. The cross-twisting of the first warp 14 and the second warp 15 also forms several periodically alternating twist knots 31 and weft channels 32. The weft channels 32 are located between two adjacent twist knots 31. That is, the twist knots 31 and the weft channels 32 are arranged alternately along the warp length direction, thereby forming a twist structure 3. Based on the above structure, the weft 2 is braided into a braid 21 by twisting multiple weft yarns together. Thus, the interwoven warp 1 and weft 2 constitute the skeleton of the wrinkle-resistant fabric.

[0024] Combination Figure 2 It should be noted that the twisted knot 31 in this embodiment refers to the cross knot structure formed by the cross twisting of the first warp 14 and the second warp 15. The twisted knot 31 forms a physical anchor point, providing support for the fabric. On this basis, the weft channel 32 is the regular weft-passing space formed between the twisted knots 31. The weft channel 32 not only provides structural strength support, but also provides a physical locking structure for the connection of the weft yarn 2, solving the problem of the warp yarn 1 and the weft yarn 2 being woven into the fabric. Furthermore, the bonding method in this embodiment does not require resin cross-linking, or in other words, eliminates the necessity of chemical adhesives. On this basis, it also achieves the effect of wrinkle resistance and crispness of the fabric by improving the structural support capacity of the space, further eliminating the unnecessary addition of chemical reagents for wrinkle resistance, and eliminating formaldehyde release from the source. The knot structure can still remain intact after several washes.

[0025] Preferably, the axial spacing of the twisted knots 31 is 0.5–2 mm, and the width of the weft channel 32 is 0.3–1 mm.

[0026] like Figure 1 As shown, the warp 1 includes corrugated warp 11 and support warp 12 arranged periodically. Each unit centimeter contains 3 to 5 periodic units. Each group of periodic units includes three corrugated warp 11 and one support warp 12. On the other side of the support warp 12, there are three corrugated warp 11 arranged in a mirror image of the three corrugated warp 11. It should be noted that due to the characteristics of the fibers, the mirror image arrangement of the corrugated warp 11 cannot achieve a perfectly symmetrical state, but it is sufficient to meet the overall skeleton shape arrangement.

[0027] Preferably, the path of the corrugated warp yarn 11 extends in a sinusoidal wave shape, and the elongation of the supporting warp yarn 12 is ≤5%. The corrugated structure of the corrugated warp yarn 11 gives the fabric lateral elastic recovery force. That is, the corrugated warp yarn 11 is arranged in a meandering state to accumulate recovery force through amplitude compression when subjected to lateral force, i.e., to disperse external force through bending shape. The processing of the corrugated warp yarn 11 is achieved by heat setting. Taking advantage of the glass transition temperature of PET raw material, it is preheated, set, and cooled. At the same time, the heat setting process is conducive to maintaining the shape of the twist knot 31 and the weft channel 32. Preferably, the path of the supporting warp 12 extends in a straight line, and the elongation of the corrugated warp 11 is 8-15%. The supporting warp 12 provides longitudinal rigid support, that is, the supporting warp 12 is relatively straight and provides rigid support in the longitudinal direction to suppress permanent deformation. In summary, the corrugated warp 11 and the supporting warp 12 of the warp 1, together with the weft 2, interweave to form a grid structure. Through elastic deformation, the structure adapts to changes in shape, while providing lateral connection and elastic support on the warp 11, which together improves the overall strength and wrinkle resistance of the fabric, and also helps to improve breathability.

[0028] Combination Figure 2-3 As shown, the twist of the braided body 21 is 200–500 twists / meter. The twisting and weaving of the braided body 21 can improve tensile and tear resistance. In this embodiment, the regular braided body 21 can help improve the wrinkle resistance of the fabric; such as Figure 2 As shown, the braided body 21 penetrates into the weft channel 32, and the ratio of its diameter to the width of the weft channel 32 is 1:1.2–1:1.8, which ensures that the weft yarn is tightly filled while retaining elastic sliding space. Specifically, the high twist structure of the braided body 21 can resist shear force, and the 1:1.2–1:1.81 design can ensure tight filling while retaining a 0.05mm rebound gap, suppressing water washing displacement, and the weft yarn 2 is not easy to slip and wrinkle after water washing.

[0029] This embodiment achieves a superposition of multiple anti-wrinkle capabilities by combining the physical interlocking structure of the twisted knots of the warp yarns and the braided structure of the weft yarns with the lateral elastic recovery force of the corrugated warp yarns and the longitudinal rigid support of the supporting warp yarns.

[0030] This application discloses an anti-wrinkle fabric structure that replaces traditional chemical resin cross-linking with a physical interlocking structure of warp yarn twist knots and weft yarn braids, eliminating the risk of formaldehyde release at the source. The corrugated warp yarns support the fabric's lateral elastic recovery ability, while the supporting warp yarns provide longitudinal rigid support. The periodic arrangement of the two forms a fabric anti-wrinkle skeleton with dynamic cushioning. At the same time, the combination of the braids and the weft yarn channels allows the weft yarns to slide slightly when subjected to external forces, but there is no displacement after washing, enabling the fabric to achieve anti-wrinkle, breathable, and environmentally friendly properties.

[0031] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
