Abstract

The present application relates to the technical field of fabric weaving, and provides a wool-ultra-high molecular weight polyethylene large jacquard fabric, which comprises a surface fabric, an intermediate fabric and a back fabric; the three-layer fabric is connected by large jacquard composite organization; the surface fabric is connected with the back fabric by point connection formed by linking organization; and the intermediate fabric is connected with the surface fabric and the back fabric by line connection formed by long floating threads. Thus, the present application is woven by large jacquard composite organization once, and the three-layer fabric is directly interwoven and formed in the weaving process. The surface fabric is used for linking yarn, which improves the interlayer bonding force and avoids interlayer peeling. At the same time, the difference in shrinkage rate of the surface fabric and the back fabric produces bulging and bubbling, which forms a static air layer in the fabric, and significantly improves the heat preservation performance. The lycra component of the back fabric provides elastic recovery rate, and the three-dimensional plush finishing forms a delicate suede, which improves the comfort of contact with the skin. The present application also provides a preparation method and a garment.

Description

Technical Field

[0001] This invention belongs to the field of fabric and textile technology, and particularly relates to a wool-ultra-high molecular weight polyethylene jacquard fabric, its preparation method, and finished garment. Background Technology

[0002] In the field of protective and thermal insulation fabrics, especially in outdoor work, extreme environment wear, and high-end protective clothing, the requirements for the comprehensive performance of fabrics are becoming increasingly stringent. They need to possess excellent protective properties (such as cut resistance, high strength, and abrasion resistance) while also ensuring good warmth retention and skin-friendly comfort. Simultaneously, the fabric must be lightweight and integrated to avoid the problems of bulkiness, poor breathability, and easy delamination caused by multi-layer composites. Furthermore, it must meet the differentiated needs of different parts of the fabric for windproofing and breathability, achieving localized functional optimization.

[0003] Chinese patent CN 119329133 A discloses a wool outdoor fabric based on aerospace materials. This fabric uses ultra-high molecular weight polyethylene (UHMWPE) masterbatch yarn as the core yarn, and prepares a three-component composite yarn by alternately spirally winding wool yarn and polyester masterbatch yarn. This is then woven into a base fabric and laminated with a modified bio-based TPU film to obtain the fabric. The aim is to combine the protective properties of UHMWPE with the skin-friendly warmth of wool. However, this technology has significant drawbacks: 1. The layered composite process of "woven base fabric + composite TPU film" relies on hot-pressing of the layers with a hot-melt web film. Long-term wear and washing can easily lead to interlayer peeling, and the high temperature of the composite may cause film aging, further reducing fabric durability. 2. It does not employ a layered structural design, relying solely on a single composite yarn to achieve performance integration. It cannot separately optimize protective, warm, and skin-friendly functions; protective properties depend on the core yarn, and the improvement in warmth and skin-friendliness is limited. 3. It does not involve differentiated adjustments to the fabric structure, making it impossible to achieve functional zoning for localized windproofing and breathability, and thus difficult to adapt to the wearing needs of different parts of the body.

[0004] Chinese patent CN202411597390.5 discloses a method for manufacturing a composite fabric of wool and ultra-high molecular weight polyethylene (UHMWPE) fiber. The method involves spinning wool and UHMWPE fibers together, achieving the composite through alternating warp and weft yarns. While this technology improves the fabric's strength and abrasion resistance, it suffers from the following problems: Since the composite is achieved through yarn plying, the fabric has a single-layer structure, failing to form a three-dimensional insulating air layer, resulting in limited warmth retention. The fabric exhibits uniform performance across the entire piece, making it impossible to achieve differentiated functional designs (such as zoned control of localized windproofing and breathability); the elongation at break of pure UHMWPE fabric is only 3.5%; it has a high thermal conductivity, feels cold to the touch, and is not resistant to high temperatures.

[0005] In addition, existing technologies also employ three-layer composite processes for protective and thermal insulation fabrics. These fabrics are typically made by bonding an outer protective layer, a middle thermal insulation layer, and an inner skin-friendly layer using adhesives and hot pressing. However, these fabrics generally suffer from poor interlayer bonding, easy delamination and peeling, and are heavy and not breathable. Furthermore, the composite process requires specialized equipment, resulting in high investment costs and a high scrap rate. Moreover, it cannot achieve synergistic optimization of the structure after one-piece molding. Some jacquard fabrics attempt to achieve performance differences through density control, but these are mostly single-layer or double-layer structures, failing to combine jacquard technology with a three-layer integrated structure. This makes it impossible to balance protection, warmth, and localized functional differentiation, and presents a contradiction between breathability and warmth retention—high-density areas offer good warmth and windproofing but poor breathability, while low-density areas offer good breathability but insufficient warmth and windproofing, making it difficult to achieve a synergistic balance between the two.

[0006] Therefore, existing technologies, whether for layered composite fabrics, blended fabrics, or ordinary jacquard fabrics, all suffer from the following core defects: 1. Multi-layer composite fabrics are prone to delamination and have poor durability, while one-piece woven fabrics have limited functions and cannot meet the multiple needs of protection, warmth and skin-friendliness. 2. Without utilizing jacquard weaving techniques to differentiate the inner layer structure, it is impossible to achieve a synergy between localized windproof and warmth retention (tight structure) and localized breathability (loose structure) in the fabric, making it difficult to adapt to the functional needs of different parts of the human body. 3. Lacking a coordinated design of three integrated layers, it cannot form a 3D air layer through inner layer shrinkage, resulting in limited heat retention efficiency; 4. It is difficult to balance protection, warmth, and breathability, making it impossible to achieve multi-functional zone optimization on a single fabric.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0008] To address the aforementioned shortcomings, this invention provides a wool-ultra-high molecular weight polyethylene jacquard fabric, which solves the technical problems of existing fabrics such as interlayer peeling, limited functionality, and poor comfort.

[0009] To address the above problems, the present invention provides a wool-ultra-high molecular weight polyethylene jacquard fabric, comprising an outer fabric, a middle fabric, and an inner fabric; the three fabrics are interwoven and connected by a jacquard composite structure. The outer fabric is connected to the inner fabric in a dotted manner through a bonding structure, and the middle fabric is connected to the outer fabric and the inner fabric in a linear manner through long floats.

[0010] In the wool-ultra-high molecular weight polyethylene jacquard fabric of the present invention, the bonding structure is formed by the surface warp bonding method.

[0011] According to the present invention, the wool-ultra-high molecular weight polyethylene jacquard fabric is made of ultra-high molecular weight polyethylene yarn; the surface fabric is plain weave with a warp density of 300-400 threads / 10cm and a weft density of 280-350 threads / 10cm; the yarn specification is 100D-300D, and the breaking strength is ≥30cN / dtex. The intermediate layer fabric 2 is woven from low-count network yarn with yarn specifications of 300D-500D / 48-96F and network density of 80-120 loops / m. The inner layer fabric is made of high-count wool yarn containing low-temperature Lycra; the yarn specifications are 48Nm-80Nm, and the spandex content is 3%-8%; the structure of the inner layer fabric is a variable structure.

[0012] According to the wool-ultra-high molecular weight polyethylene jacquard fabric of the present invention, the high-count wool yarn of the inner layer fabric has a setting temperature of 120°C, a machine speed of 35m / min, and an overfeed rate of 18%.

[0013] According to the wool-ultra-high molecular weight polyethylene jacquard fabric of the present invention, the wet and heat shrinkage rate of the inner layer fabric is 12~18%, the wet and heat shrinkage rate of the middle layer fabric is ≤3%, and the wet and heat shrinkage rate of the outer layer fabric is ≤1%.

[0014] According to the wool-ultra-high molecular weight polyethylene jacquard fabric of the present invention, the variable weave of the inner layer fabric has specific weave structures in different areas of the fabric, forming corresponding functional zones, specifically: The inner fabric has a plain weave structure, forming a warming zone; the warp and weft of the inner fabric in the warming zone are tightly interwoven, forming a still air layer with a thermal resistance value ≥0.15 m. 2 *K / W; The inner fabric has a variable weave structure that creates a perforated area; The inner layer fabric has a variable weave, which is a twill weave, forming a transition zone.

[0015] According to the wool-ultra-high molecular weight polyethylene jacquard fabric of the present invention, the perforated structure is a 6-perforated structure or a honeycomb structure, forming regular gaps, with a porosity ≥15% and an air permeability ≥80 mm / s.

[0016] According to the wool-ultra-high molecular weight polyethylene jacquard fabric of the present invention, the inner layer fabric is a 1 / 2 twill weave.

[0017] A preparation method for preparing the wool-ultra-high molecular weight polyethylene jacquard fabric includes the following steps: S1, made from wool elastic yarn 10tex / 2-12.5tex / 2 wool elastic yarn is spun from dyed, stretched, and non-permanently shaped wool with 30D low-temperature Lycra with a 3.2-fold draw. S2, Warping Wool elastic yarn and ultra-high molecular weight polyethylene fiber are slit and warped in a 1:1 ratio. S3, weaving Wool elastic yarn, low-count polyester network yarn and ultra-high molecular weight polyethylene yarn are weft-beaten in a 1:1:1 ratio; through a large jacquard loom, wool elastic yarn is interwoven into the inner layer fabric, ultra-high molecular weight polyethylene yarn is interwoven into the outer layer fabric, and low-count polyester network yarn is filled between the two to form the middle layer fabric. S4, Post-processing The inner layer fabric is steamed under humid and hot conditions, and the wool elastic yarn rebounds and returns to its pre-stretch state. Heat setting is performed at 120°C, and the low-temperature Lycra in the wool elastic yarn rebounds. The inner layer fabric shrinks and causes the outer and middle layers of fabric to bulge and wrinkle, thus obtaining the fabric.

[0018] A garment made using the aforementioned wool-ultra-high molecular weight polyethylene jacquard fabric; comprising a garment body, the garment body being the insulating area; the garment having breathable areas at the armpits, cuffs, or side arms; and the garment having transition areas at the back or side arms; the insulating area, breathable area, and transition area occupying 60%, 25%, and 15% of the total area of ​​the garment, respectively.

[0019] In summary, the wool-ultra-high molecular weight polyethylene jacquard fabric of this invention is woven in a single step using a jacquard composite structure, with the three layers of fabric directly interwoven during the weaving process. Ultra-high molecular weight polyethylene yarn is used as the outer layer for bonding, improving interlayer bonding strength (exceeding 25N / 5cm) and preventing interlayer delamination. Simultaneously, the difference in shrinkage rates between the outer and inner layers creates raised folds, forming an additional static air layer within the fabric, significantly improving thermal insulation. The inner layer is woven from high-count wool yarn containing spandex (low-temperature Lycra), with the Lycra component providing 8-15% elastic recovery. A three-dimensional fleece finishing process creates a fine nap, enhancing comfort against the skin. This invention also provides a preparation method and a finished garment.

Detailed Implementation

[0021] See Figure 1-3 The present invention provides a wool-ultra-high molecular weight polyethylene jacquard fabric, comprising an outer fabric 1, a middle fabric 2, and an inner fabric 3; the three fabrics are interwoven and connected by a jacquard composite structure. The outer fabric 1 is connected to the inner fabric 3 by a splicing structure to form a point-like connection, and the middle fabric 2 is connected to the outer fabric 1 and the inner fabric 3 by long floats to form a linear connection. Preferably, the bonding structure of the present invention is formed by epidermal bonding.

[0022] As one embodiment, the surface fabric 1 of the present invention is woven from ultra-high molecular weight polyethylene (UHMWPE) yarn; the surface fabric 1 has a plain weave structure with a warp density of 300-400 threads / 10cm and a weft density of 280-350 threads / 10cm; the yarn specification is 100D-300D, and the breaking strength is ≥30cN / dtex. The use of ultra-high molecular weight polyethylene (UHMWPE) as the surface fabric 1 in this invention provides high strength, cut resistance, and abrasion resistance.

[0023] Combination Figure 2 In this invention, scissors 4 are used to cut open the outer fabric 1 and fold the cut opening to expose the middle fabric 2. The middle fabric 2 is woven from low-count yarn with a yarn specification of 300D-500D / 48-96F and a yarn density of 80-120 loops / m. The middle fabric 2 primarily serves a warming function, employing a continuous weft float length and interlacing with the outer fabric 1 and inner fabric 3 only at the seams to form a fluffy, warming layer.

[0024] Combination Figure 3 In this invention, scissors 4 are used to further cut the middle layer fabric 2 of the fabric, and the cut is folded over to expose the inner layer fabric 3. The inner layer fabric 3 of this invention is woven from high-count wool yarn containing spandex (low-temperature Lycra); the yarn specifications are 48Nm-80Nm, and the spandex content is 3%-8%; the weave of the inner layer fabric 3 is a variable weave. The inner layer fabric 3 of this invention undergoes a three-dimensional fleece finishing process to form a skin-friendly fleece surface.

[0025] As one embodiment, the inner layer fabric 3 of the present invention has a variable weave structure: plain weave, openwork weave, or twill weave.

[0026] Furthermore, unlike existing Lycra yarn (setting temperature 185°C), the inner fabric 3 of this invention uses high-count wool yarn containing low-temperature Lycra, with a setting temperature of 120°C, a machine speed of 35m / min, and an overfeed rate of 18%. Its melting point is close to that of the ultra-high molecular weight polyethylene (UHMWPE) of the outer fabric 1 (130-136°C), thus reducing the impact of high temperatures on the fibers of the outer fabric 1 during the fabric preparation process.

[0027] Even better, the wet heat shrinkage rate of the inner fabric 3 of the present invention is 12~18%, the wet heat shrinkage rate of the middle fabric 2 is ≤3%, and the wet heat shrinkage rate of the outer fabric 1 is ≤1%.

[0028] During the fabric preparation process, the inner fabric 3 experiences significant shrinkage during the subsequent wet heat finishing process, resulting in substantial longitudinal shrinkage. This, in turn, causes the outer fabric 1 and the middle fabric 2 to form raised pores, creating a 3-8 mm thick static air layer inside the fabric, thus improving its thermal insulation performance. Experimental verification shows that this invention can improve the fabric's thermal insulation performance by 15%-25%.

[0029] The wool-ultra-high molecular weight polyethylene (UHMWPE) jacquard fabric of this invention is woven in a single step using a jacquard composite structure, with the three layers of fabric directly interwoven during the weaving process. UHMWPE yarn is used as the outer layer fabric 1 for bonding, improving interlayer bonding strength (exceeding 25N / 5cm) and preventing interlayer delamination. Simultaneously, the difference in shrinkage rates between the outer and inner layers creates raised folds, forming an additional static air layer within the fabric, significantly improving thermal insulation. The inner layer fabric 3 is woven from high-count wool yarn containing spandex (low-temperature Lycra), with the Lycra component providing an 8-15% elastic recovery rate. A three-dimensional fleece finishing process creates a fine nap, enhancing comfort against the skin.

[0030] See Figure 4 As one embodiment, the variable weave of the inner fabric 3 of the present invention has specific weave structures in different areas of the fabric, forming corresponding functional areas, specifically: See Figure 6-8 The inner fabric 3 has a plain weave structure, forming the insulation zone 5; the inner fabric 3 of the insulation zone 5 has a tight warp and weft interweaving, forming a still air layer with a thermal resistance value ≥0.15 m. 2 *K / W; Optionally, to provide better protection, the yarn of the outer fabric 1 of the insulation zone 5 is fine and dense; the yarn of the middle fabric 2 is coarse and the yarn of the inner fabric 3 is fine and dense; the yarn arrangement adopts the 2a1b2c scheme.

[0031] See Figure 9-11 The inner fabric 3 has a variable structure of perforated structure, forming a breathable zone 51; further, the perforated structure is a 6-perforated structure or a honeycomb structure, forming regular gaps, with a porosity ≥15% and an air permeability ≥80 mm / s.

[0032] See Figure 12-14 The inner fabric 3 has a variable weave of twill, forming a transition zone 52; preferably, the inner fabric 3 has a 1 / 2 twill weave, which is between tight and loose.

[0033] The present invention also provides a method for preparing the wool-ultra-high molecular weight polyethylene jacquard fabric, comprising the following steps: S1, made from wool elastic yarn 10tex / 2-12.5tex / 2 wool elastic yarn is spun from dyed, stretched, and non-permanently shaped wool with 30D low-temperature Lycra with a 3.2-fold draw. S2, Warping Wool elastic yarn and ultra-high molecular weight polyethylene fiber are slit and warped in a 1:1 ratio. S3, weaving Wool elastic yarn, low-count polyester network yarn and ultra-high molecular weight polyethylene yarn are weft-beaten in a 1:1:1 ratio; through a large jacquard loom, wool elastic yarn is interwoven to form inner fabric 3, ultra-high molecular weight polyethylene yarn is interwoven to form outer fabric 1, and low-count polyester network yarn is filled between the two to form middle fabric 2. S4, Post-processing The inner fabric 3 is steamed under humid and hot conditions, and the wool elastic yarn rebounds and returns to its pre-stretch state. Heat setting is performed at 120°C, and the low-temperature Lycra in the wool elastic yarn rebounds. The inner fabric 3 shrinks and causes the outer fabric 1 and the middle fabric 2 to produce raised bubbles, thus obtaining the fabric.

[0034] As one embodiment, the warping in step S2 is precisely controlled by layering and splitting axes; the ultra-high molecular weight polyethylene fibers of the surface fabric 1 are warped at a warping tension of 18±2cN and a low speed of 200m / min, in conjunction with a hair-feathering roller to reduce fuzzing. The low-count polyester network yarn of the middle layer fabric 2 is warped with constant tension of 25cN and a high-voltage electrostatic elimination roller is added to prevent the chemical fiber filaments from breaking. The wool elastic yarn of the inner fabric 3 is warped with low tension of 15±1cN in an environment with a humidity of 65%RH to suppress electrostatic adsorption. The warp yarns of the three-layer fabric are independently split, with a warp beam spacing of ≥15cm; this avoids interlacing friction and ensures a tension difference of ≤3%, providing a high-precision warp yarn foundation for jacquard weaving.

[0035] See Figure 5 The present invention also provides a garment made using the aforementioned wool-ultra-high molecular weight polyethylene jacquard fabric.

[0036] As one embodiment, the garment includes a garment body, which is a warming area 5; the garment has breathable areas 51 under the armpits, cuffs, or side arms; these areas are breathable and facilitate heat dissipation. The garment has a transition area 52 at the back or side arm position; this area combines heat dissipation and warmth retention functions.

[0037] Furthermore, the warming zone 5, the breathable zone 51, and the transition zone 52 account for 60%, 25%, and 15% of the total area of ​​the garment, respectively.

[0038] The fabric of this invention underwent multiple performance tests according to industry-standard national criteria, and all results reached a high level, as detailed in Table 1.

[0039] Table 1. Fabric performance testing standards and results In summary, this invention provides a wool-ultra-high molecular weight polyethylene (UHMWPE) jacquard fabric, woven in a single step using a jacquard composite weave, with the three layers directly interwoven during the weaving process. UHMWPE yarn serves as the outer layer for bonding, improving interlayer bonding strength (exceeding 25N / 5cm) and preventing delamination. Simultaneously, the difference in shrinkage rates between the outer and inner layers creates raised folds, forming an additional static air layer within the fabric, significantly improving insulation performance. The inner layer is woven from high-count wool yarn containing spandex (low-temperature Lycra), with the Lycra component providing 8-15% elastic recovery. A three-dimensional fleece finishing process creates a fine nap, enhancing comfort against the skin. This invention also provides a preparation method and a finished garment.
