Description

Technical Field

[0001] This invention relates to the field of jacket technology, specifically to a jacket that combines an imitation oil-wax texture with a three-in-one composite process. Background Technology

[0002] As outdoor lifestyles permeate urban commuting scenarios, and with the continued popularity of "gorpcore" (outdoor functional style) and "neo-retro" styles, consumer demand for transitional season outerwear is no longer limited to simple warmth or wind protection; the market is showing a strong demand for clothing that combines the following characteristics: 1. Enhanced surface texture: Traditional synthetic fiber fabrics have been gradually marginalized in the market due to their glaring luster and strong plastic feel. Consumers prefer retro surfaces with a natural, worn, waxy, or chalky feel, and pursue an aesthetic preference for "mineral-free, natural texture". 2. Functional invisibility: Water-repellent and breathable functions should be achieved through the fabric itself, rather than relying on thick coatings or additional functional layers to maintain the lightness of the garment.

[0003] Currently, most shape memory fabrics on the market use chemical resin finishing to achieve wrinkle resistance or rely on metal coatings to maintain shape. These technologies have the following shortcomings: Fabrics treated with chemical resins feel stiff, have reduced breathability, and are not resistant to washing. Metallic coatings increase fabric weight and pose environmental risks; Existing technologies fail to systematically integrate surface texture treatment with multi-layered composite structures, making it difficult to simultaneously meet multiple requirements for appearance, feel, and functionality.

[0004] Therefore, developing a transitional season jacket that combines a natural waxy texture, crispness and shape retention, lightweight comfort, and basic water-repellent properties, along with its fabric preparation method, has significant market value. Summary of the Invention

[0005] The purpose of this invention is to provide a jacket that combines an imitation oil wax texture with a three-in-one composite process. Through the synergistic effect of the physical modification of the A layer with the imitation oil wax treatment and the three-in-one composite process of the knitted base, the technical problems of poor texture and difficulty in achieving both crispness and comfort in the prior art of chemical fiber fabrics are solved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a jacket that combines an imitation oil wax texture with a three-in-one composite process, and is made of three-layer composite fabric; The three-layer composite fabric includes a surface layer (A), a functional intermediate layer (B), and a skin-friendly bottom layer (C). Layer A is a polyester-nylon fabric that has undergone physical modification to mimic oil wax, possessing an oil wax texture, crispness, shape retention, and slight water-repellent properties; Layer B is a PU waterproof membrane; Layer C has a weight of 100g / m³. 2 Polyester-spandex blended knitted fabric, composed of 92% polyester and 8% spandex, has skin-friendly properties; The jacket features a classic deck suit style, with corduroy and plaid cotton patchwork trim.

[0007] Furthermore, the surface layer of layer A fabric yarn: the warp yarn is PNH high-shrinkage polyester-nylon composite yarn FDY, measured at 56D, with a composition of 70% polyester and 30% nylon; the weft yarn is 50D / 36FP semi-dull T400FDY, 100% polyester.

[0008] Furthermore, the A-layer physical modification imitation oil wax treatment is a purely physical modification, without the addition of chemical resins or the use of metal coatings; through precise control of tension and pressure during the processing, a compact "muscular" structure is formed inside the fabric, and microfibrillation occurs on the fiber surface, reducing the luster of chemical fibers and forming a chalky retro imitation oil wax surface.

[0009] Furthermore, the complete fabric preparation process includes the following steps: S1: Preparation of Layer A The greige fabric is desized and split at 100℃ and then dyed; the initial setting temperature is 150℃, the machine speed is 25m / min, and the overfeed is 13%; an imitation oil wax coating and calendering treatment are carried out, with a calendering temperature of 150℃ and a pressure of 7MPa; then reverse setting is carried out, with a reverse setting temperature of 150℃, a machine speed of 25m / min, and an overfeed of 0%; the fabric is then air-cooled to 60℃ to obtain the A-layer semi-finished product. S2: Three-layer composite The semi-finished product (layer A), PU film (layer B), and knitted fabric (layer C) are hot-pressed together; the hot roller temperature is 130℃, the pressure is 5MPa, and the speed is 8m / min; after lamination, the mixture is cured at 50℃ for 48 hours. S3: Post-shaping and inspection After lamination, the fabric is loosely washed and then stretched and shaped to eliminate curling and stabilize the width. S4: Garment Production After cutting, sewing, and casual ironing to set the shape, the finished jacket is produced.

[0010] Furthermore, the composite fabric has a waterproof rating of >150,000 MVP, a moisture permeability rating of >10,000, and a peel strength of ≥3.5 N / cm.

[0011] Furthermore, layer B is a PU film, and layer C is a 100g / m² blended knitted fabric of 92% polyester and 8% spandex.

[0012] Furthermore, the jacket is sewn with matching 80# core-spun sewing thread, with a stitch length of 6 stitches per 1.5cm.

[0013] Furthermore, the garments undergo a casual ironing and shaping process.

[0014] Furthermore, the A-layer's imitation oil-wax texture is formed by microscopic modification of fibers, eliminating the need for subsequent waxing and maintenance.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The A layer of this invention imparts a permanent natural fuzzy feel, oily and waxy leather feel, and high shape retention to synthetic fiber fabrics through physical modification technology without using chemical resins or metal coatings; this technology solves the market's pain point of demanding "mineral-free, natural texture" shape memory fabrics. Unlike the common approach of achieving "wrinkle resistance" through resin finishing, this technology employs a purely physical modification method. Its core process does not involve adding chemical stiffeners to the fabric surface, but rather alters its physical properties at the fiber molecular level by precisely controlling the tension and pressure during physical processing. Employing a multi-segment special tension adjustment device, a precisely controlled mechanical force is applied to the fabric during processing. This physical action causes the fabric to develop a compact structure resembling "worked muscles" (i.e., "muscular texture"), thus achieving a lasting stiffness and elasticity without increasing chemical burden. Ultimately, this gives the originally soft and easily collapsed polyester / nylon fabric a crisp and structured feel similar to linen or wool, and this texture can withstand repeated washing. 2. This technology not only solves the problem of fabric "stiffness", but also creates a unique "vintage" surface through post-processing: Post-processing-led: After the basic fabric is woven, it is "aged" using specific equipment and temperature and humidity conditions; Composite process system: This treatment is not a single process, but a composite process that combines chemical auxiliary treatment (using specific auxiliaries to make the fibers appropriately swollen) and physical treatment (mechanical rubbing and grinding); Surface micro-modification: Through special processes, micro-damage or microfibrilization is created on the fiber surface, thereby reducing the glaring luster of synthetic fibers and forming a natural, dry, and "chalk-like" retro surface, completely eliminating the cheap plastic feel of synthetic fibers. 3. This invention uses pure physical modification to achieve a retro oil-wax-like surface without using chemical resins or metal coatings. The fabric is breathable and washable. The hot-pressed three-in-one composite avoids the damage to the waterproof integrity caused by sewing. The three-layer structure takes into account the stiffness, shape retention, water repellency, and skin-friendly comfort, making it suitable for wearing in various transitional seasons.

[0026] The following will describe the specific solutions and implementation methods in detail: The present invention provides a jacket that combines an imitation oil wax texture with a three-in-one composite process, and is made of three-layer composite fabric; The three-layer composite fabric includes a surface layer (A), a functional intermediate layer (B), and a skin-friendly bottom layer (C). Layer A is a polyester-nylon fabric that has undergone physical modification to mimic oil wax, possessing an oil wax texture, crispness, shape retention, and slight water-repellent properties; Layer B is a PU waterproof membrane; Layer C has a weight of 100g / m³. 2 Polyester-spandex blended knitted fabric, composed of 92% polyester and 8% spandex, has skin-friendly properties; The jacket features a classic deck suit style, with corduroy and plaid cotton patchwork trim.

[0027] Furthermore, the surface layer of layer A fabric yarn: the warp yarn is PNH high-shrinkage polyester-nylon composite yarn FDY, measured at 56D, with a composition of 70% polyester and 30% nylon; the weft yarn is 50D / 36FP semi-dull T400FDY, 100% polyester.

[0028] Furthermore, the A-layer physical modification imitation oil wax treatment is a purely physical modification, without the addition of chemical resins or the use of metal coatings; through precise control of tension and pressure during the processing, a compact "muscular" structure is formed inside the fabric, and microfibrillation occurs on the fiber surface, reducing the luster of chemical fibers and forming a chalky retro imitation oil wax surface.

[0029] Furthermore, the complete fabric preparation process includes the following steps: S1: Preparation of Layer A The warp yarn is made of (PNH) high shrinkage polyester / nylon composite yarn FDY (measured 56D, 70% polyester / 30% nylon), and the weft yarn is made of 50D / 36FP semi-dull T400FDY (100% polyester). S11: Weaving The fabric is woven using a Tsudakoma ZW8200 Professional water jet loom, with warp and weft densities set according to the requirements of the imitation oil wax style, resulting in a tight and flat greige fabric. S12: Desizing and fiber opening: Using a Circular desizing machine (A2D-0552WM-MPC30), the composite yarn was made ultra-fine and opened at 100℃. S13: Staining: The dyeing process was completed using a Circular overflow dyeing machine (CUT-XF-2L) with the following dye formulation: S-5BL: 0.85%, S-4RL: 1.6%, S-3BG: 0.72% / 2B: 0.32%, GR: 1.01%, N-BL: 0.08%. S14: Shaping: The Monforts ST-2000 stenter is used. Temperature: 150℃, machine speed: 25m / min, overfeed: 13%, air speed: 7m / s. The fabric must be cooled to 60℃ after exiting the machine. S15: Imitation oil wax finish: The Yessing H-10000-3 coating machine was used, with a speed of 8 m / min and a thickness of 10 m / min. 2 Drying temperature: 70-95℃, internal moisture removal temperature: 95℃, oil and wax curing temperature: 110℃, fabric output temperature: 70℃, overall air pressure control: 150Pa; The calendering was performed using an Andritz-Küsters calender (YB-2PIH) at a temperature of 150℃, a pressure of 7MPa, and a speed of 20m / min. S16: Post-processing: The reverse setting process was carried out using a Monforts ST-2000 stenter at a temperature of 150°C, a speed of 25 m / min, an overfeed of 0%, and an air velocity of 7 m / s. The fabric must be cooled to 60°C after exiting the machine to obtain a semi-finished A-layer product. S2: Three-layer composite Layer B is made of PU film, and layer C is made of 100g / m² film. 2 The polyester / spandex blended knitted fabric is composed of 92% polyester and 8% spandex. The A-layer semi-finished product with a B-layer film is used as a carrier and finally hot-pressed with the C-layer knitted fabric. A Yessing LTR1800EH laminating machine is used to bond the exposed surfaces of the C and B layers together. Key process parameters are: TEX18 / W proofness: >150000; MVP: >10000; hot roller temperature: 130℃; pressure: 5MPa; machine speed: 8m / min. After lamination, the fabric is left to cure in a 50℃ constant temperature room for 48 hours to allow the TPU film and the adhesive layers on both sides to fully cross-link and solidify, ultimately achieving a peel strength ≥3.5N / cm. S3: Post-shaping and inspection The Goller vortex loose washing machine (CYCLON A Modul 2200) is used. Pre-wash: 40℃, main wash: 55℃; cold water cooling: fabric is dropped at room temperature of 40℃. The entire piece of fabric is then stretched and shaped to eliminate composite curling and stabilize the width. S4: Garment Production Adopting a classic deck-style cut, the main body of the garment is made of the aforementioned three-layer composite fabric, with corduroy and plaid cotton fabric used for trim. The garment is cut using a computer-automated cutting bed based on the garment pattern, and all sewing is done with 80# core-spun thread in the same color, with a stitch length of 6 stitches per 1.5cm to highlight the retro handmade texture. The finished garment undergoes casual pressing and shaping to ultimately obtain a three-in-one composite jacket that combines retro fashion with transitional season wearability.

[0030] The composite fabric has a waterproof rating of >150,000 MVP, a moisture permeability rating of >10,000, and a peel strength of ≥3.5 N / cm.

[0031] Layer B is a PU film, and layer C is a 100g / m² film. 2 92% polyester + 8% spandex blended knitted fabric, with skin-friendly C layer.

[0032] The jacket is sewn with matching 80# core-spun sewing thread, with a stitch length of 6 stitches per 1.5cm.

[0033] The garments undergo a casual ironing and shaping process.

[0034] Layer A, with its imitation oil-wax texture, is formed by microscopic modification of the fibers, requiring no subsequent waxing or maintenance.

[0035] Example 1: Environmental conditions: During the transitional season of normal temperature and humidity, the temperature is 15-25℃, and the relative humidity (RH) is 40%-60%. Using all standard process parameters of claims 2-4; A layer of raw fabric, B layer of PU film, C layer of 100g / m 2 A 92% polyester / 8% spandex knitted fabric was used; the coating, calendering, lamination, curing, and washing processes all followed the parameters of the original embodiment to obtain a standard imitation oil-wax three-in-one composite jacket fabric, from which the finished jacket was made.

[0036] Example 2: Environmental conditions: High temperature and high humidity environment, 28-35℃, RH 70%-90%, hot and humid transitional environment in summer. The yarn, weaving, desizing, dyeing, setting, coating, and calendering processes are the same as in Example 1; the C layer uses 80g / m³ yarn. 2 92% polyester + 8% spandex thin knitted fabric; B layer uses PU film; composite hot pressing parameters remain unchanged, curing for 48 hours; water washing process remains unchanged; suitable for high temperature and high humidity, improving the overall moisture permeability of the fabric.

[0037] Example 3: Environmental conditions: Low-temperature and dry environment, 0-10℃, RH 20%-35%, dry and cold environment in autumn and winter. Yarn weaving, desizing and dyeing, coating and calendering are the same as in Example 1; layer C uses 120g / m 2 92% polyester + 8% spandex knitted fabric, with antistatic additives added to layer C; conventional PU film in layer B; unchanged composite, curing, and washing processes; increased fabric thickness to suit low-temperature drying environments.

[0038] Example 4: Environmental conditions: Rainy and humid outdoor environment, 10-20℃, RH 85%-95%, rainy and humid outdoor environment. The yarn weaving, desizing, dyeing, setting, coating, and calendering are the same as in Example 1; a high-waterproof PU film is selected for layer B; the bonding and hot pressing parameters remain unchanged; the curing time is extended to 56 hours; the vortex loose water washing reduces the main washing temperature to 50°C, reducing damage to the waterproof film; and improving water resistance and resistance to humid environments.

[0039] Comparative Example 1 (Environmental conditions: normal temperature and humidity, 15-25℃, RH 40-60%; traditional chemical resin stiffening treatment of two-layer fabric) The same A-layer fabric as in Example 1 was used, but the physical modification imitation oil wax process of this invention was not performed. Instead, a chemical resin stiffening treatment was used. The fabric was only two-layer composited, without a C-layer knitted underlayer. The dyeing and setting equipment was the same for the rest.

[0040] Comparative Example 2 (Environmental conditions: normal temperature and humidity, 15-25℃, RH40-60%; ordinary PU film two-in-one fabric, without A layer physical modification imitation oil wax treatment) The greige fabric yarn is the same as in Example 1, and the weaving, dyeing and finishing are completed without imitation oil wax coating or physical modification by calendering; it is directly compounded with PU film without knitted C layer.

[0041] Comparative Example 3 (Environmental conditions: normal temperature and humidity, 15-25℃, RH40-60%; traditional sewing lock-lock three-in-one fabric) The materials of layer A (grey fabric), layer B (film), and layer C (knitted fabric) are the same as in Example 1; instead of using a hot-press bonding process, the three layers are sewn together using a sewing locking method, without a hot-press curing process.

[0042] Experimental Example Samples: For each embodiment and comparative example, take the same width of fabric and cut a 30cm×30cm sample; Hydrostatic pressure was tested according to GB / T4744-2013; moisture permeability was tested according to GB / T12704.1-2009; peel strength was tested according to GB / T2790-1995; water washing test: GB / T8629-2017, 10 washes to evaluate the retention rate of imitation oil and wax texture; flexural length was evaluated according to GB / T18318.1-2001 to assess stiffness; gloss was measured using a 60° gloss meter; basis weight was tested according to GB / T4669-2008.

[0043] Table 1 shows the performance test comparison table.

[0044] Examples 1-4, employing the physical imitation oil wax + hot pressing three-in-one composite process of the present invention, showed significantly better hydrostatic pressure, peel strength, and oil wax texture retention rate after washing compared to the comparative examples. Example 2 exhibited optimal moisture permeability under high temperature and humidity conditions. Example 3 demonstrated greater bending length and better stiffness and warmth retention under low temperature and dry conditions. Example 4 showed the highest hydrostatic pressure under rainy conditions. Comparative Example 1, with its resin finishing, exhibited poor breathability and significant texture degradation after washing. Comparative Example 2, without physical modification, had high gloss and a strong synthetic plastic feel. Comparative Example 3 showed a tendency for water leakage at the sewing and locking points, and poor bonding strength.
