Description

Technical Field

[0001] The utility model relates to the technical field of reflective fabrics, in particular to a breathable reflective fabric that is washable and rainproof. Background Art

[0002] Reflective materials are not only used in the field of traffic safety, but also the continuously developed functional reflective fabrics are used in various types of casual clothing. The reflective fabrics used in clothing need to have functions such as breathability, washability, and rainproof.

[0003] The existing rainproof and breathable reflective fabrics have a one-time rainproof treatment on the reflective layer. After one wash, the rainproof performance is lost. Secondly, the reflective fabric products made by making a PU waterproof layer on the cloth base are not breathable. The current rainproof and breathable fabrics cannot meet the requirements of breathability, washability and rainproof at the same time, so it is necessary to improve the above problems. Summary of the invention

[0004] The utility model aims at the defects in the prior art that the fabrics cannot be breathable, washable and rainproof at the same time, and provides a new breathable reflective fabric that is washable and rainproof.

[0005] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:

[0006] A washable and rainproof breathable reflective fabric comprises a reflective layer and a fabric base layer, wherein the reflective layer is connected to the fabric base layer, an upper washable breathable waterproof layer is arranged on the upper side of the reflective layer, and a lower washable breathable waterproof layer is arranged on the lower side of the fabric base layer.

[0007] The utility model realizes a washable and rainproof breathable reflective fabric by arranging an upper washable breathable waterproof layer and a lower washable breathable waterproof layer, and directly connecting the reflective layer and the fabric base layer, so as to have the functions of breathability, washability, rainproof and reflective, thereby greatly improving the user experience.

[0008] Preferably, in the above-mentioned washable and rainproof breathable reflective fabric, a glass bead layer is provided between the reflective layer and the upper washable breathable waterproof layer.

[0009] The provision of the glass bead layer can ensure the reflective effect of the reflective layer.

[0010] Preferably, in the above-mentioned washable and rainproof breathable reflective fabric, the upper washable breathable waterproof layer is a wave-like structure, and the upper washable breathable waterproof layer cooperates with the glass bead layer.

[0011] The upper washable, breathable and waterproof layer with a quasi-wavy structure can provide more air flow space, thereby enhancing the breathability of the fabric and helping to form a waterproof barrier on the surface of the fabric. The upper washable, breathable and waterproof layer cooperates with the glass bead layer, and corresponds and fits in structure, ensuring the reflective effect of the reflective layer. The surface of each glass bead in the glass bead layer forms an upper washable, breathable and waterproof layer with a quasi-wavy structure. During the soaking and drying process, the gaps between the glass beads will allow the water-repellent agent to penetrate into the base fabric. After being fixed and combined at high temperature, it is both waterproof and breathable, and the water-repellent performance is improved.

[0012] Preferably, in the above-mentioned washable and rainproof breathable reflective fabric, the particle size of the glass beads in the glass bead layer is 32 μm to 55 μm.

[0013] Glass beads with a particle size of 32μm to 55μm can better reflect light and provide a better reflective effect. When selecting, a single particle size will be selected, among which the two particle size segments of 32μm to 42μm and 50μm to 55μm have better effects and more uniform adhesion to the washable, breathable and waterproof layer.

[0014] Preferably, in the above-mentioned washable and rainproof breathable reflective fabric, the surface of the glass bead layer is provided with an aluminum-plated layer.

[0015] The aluminum coating can significantly improve the reflective ability of the glass bead layer and ensure the durability of the reflective effect.

[0016] Preferably, in the above-mentioned washable and rainproof breathable reflective fabric, the base fabric is a pongee layer or a nylon layer.

[0017] The polyester pongee layer and the nylon spun layer have a soft and comfortable hand feel, which improves the comfort of the fabric. In addition, the polyester pongee layer and the nylon spun layer have good air permeability, high strength, and wear resistance, making the fabric more durable. The polyester pongee layer and the nylon spun layer can provide better drape, and also have good wrinkle resistance and applicability. The types of clothing made of the fabric of the utility model are more diverse, more fit and more beautiful.

[0018] Preferably, in the above-mentioned washable and rainproof breathable reflective fabric, the thickness of the upper washable breathable waterproof layer is 1 μm to 5 μm.

[0019] The above thickness can ensure washability, breathability and waterproofness, while maintaining lightness and improving comfort through thin layer design.

[0020] Preferably, the production process of the washable and rainproof breathable reflective fabric described above comprises the following steps:

[0021] S1: Take a PET film, apply water-based bead-planting glue on the PET film, and then treat it in an oven, take glass beads with a particle size of 32μm to 55μm, adhere the glass beads to the PET film to form a glass bead layer, and then use a vacuum aluminum plating machine to aluminum the glass bead layer to form an aluminum plating layer, thereby completing the manufacture of the reflective layer;

[0022] S2: Take the release film, apply fabric glue on one side of the release film, take the polyester pongee layer or the nylon spun layer as the base fabric, compound the release film and the base fabric with the fabric glue, then peel off the release film, attach the reflective layer, peel off the PET film of the reflective layer, and form a semi-finished fabric;

[0023] S3: Put the semi-finished fabric into the drying room for curing for 3 to 5 days at room temperature or 50℃ to 80℃. After the curing is completed, the semi-finished fabric is soaked in the water-repellent agent through the unit for 5 to 10 seconds. After the soaking is completed, the semi-finished fabric is dried at 5kg / cm 2 ~7kg / cm 2 The excess water-repellent on the semi-finished fabric is dried under line pressure, and then the semi-finished fabric is locked by the unit, and then the water-repellent is attached and fixed in an oven at a temperature of 170℃~190℃ to form an upper washable breathable waterproof layer and a lower washable breathable waterproof layer, and finally a washable and rainproof breathable reflective fabric is obtained.

[0024] Step S1 is used to manufacture the reflective layer through bead planting and aluminum plating processes, which simplifies the production process of the reflective layer and improves production efficiency. Using water-based bead planting glue instead of solvent-based adhesives reduces the emission of volatile organic compounds and is more environmentally friendly. The aluminum plating layer is formed on the glass bead layer by vacuum aluminum plating technology, which significantly improves the reflective efficiency. The stability of the PET film and the adhesion of the glass beads, plus the protection of the aluminum plating layer, improve the durability of the reflective layer. Oven treatment ensures the uniform curing of the bead planting glue and improves the consistency of product quality. When selecting glass beads, a single particle size will be selected, among which the two particle size segments of 32μm~42μm and 50μm~55μm have better effects, and the adhesion effect with the washable, breathable and waterproof layer is also more uniform. Aluminum plating can be carried out by evaporation using a vacuum aluminum plating machine, taking into account both cost and effect.

[0025] Step S2 is used to form a semi-finished fabric through a gluing and laminating process. By using a release film and fabric glue, the laminating process is simplified and production efficiency is improved. The use of fabric glue ensures a firm bond between the base fabric and the reflective layer. The laminating process improves the structural stability of the fabric, making it more durable and washable.

[0026] Step S3 is used to obtain the final fabric through curing, soaking, drying, and attachment and fixing processes. Through curing treatment, the physical and chemical properties of the fabric are stabilized, reducing deformation or damage during subsequent processing. Curing treatment helps the fabric glue and water-repellent agent to finally bond more firmly to the fabric and enhance adhesion. The fabric after curing is less likely to be damaged during the washing process, which improves the washability. Through the soaking and drying process, it is ensured that the water-repellent agent evenly penetrates each layer to react and firmly adheres, thereby improving the water-repellent performance. Through the units, especially the fully automated units, the steps of soaking, drying and locking are carried out, which reduces manual operation and improves production efficiency. The attachment and fixing treatment is carried out in an oven at a temperature of 170°C to 190°C, so that the water-repellent agent is more firmly bonded to the surface of the glass bead layer, and at the same time, it is combined with the yarn of the cloth base layer, and the attachment is more firmly.

[0027] The utility model adopts the above-mentioned design to immerse and roll the semi-finished fabric and fix it in an oven, thereby obtaining a washable and rainproof breathable reflective fabric, which has the functions of breathability, washability, rainproof and reflective at the same time, greatly improving the use experience. The utility model soaks the semi-finished fabric in a water-repellent agent, quickly and under high pressure squeezes out the excess water-repellent agent, and at the same time allows the water-repellent agent to thoroughly penetrate into the yarn of the base layer of the fabric and the surface of the glass bead layer, and then uses the high temperature of the oven to allow the water-repellent agent to react with the base layer of the fabric and the glass bead layer, and finally rolls up the washable and rainproof breathable reflective fabric.

[0028] Preferably, in the above-mentioned production process of a washable and rainproof breathable reflective fabric, the fabric glue is a mixture of acrylic modified adhesive, aluminum paste, thickener, curing agent, solvent and stearic acid in a mass ratio of 60-80:1-3:3-5:2-3:15-20:0.5-1.

[0029] The mixed formula of the above mass ratio provides better adhesion and ensures a strong bond between the base layer and the reflective layer. The acrylic modified adhesive has good water resistance and chemical resistance, so that the fabric glue can remain stable during the daily washing process of the fabric. The addition of aluminum paste enhances the wear resistance and weather resistance of the fabric and improves the service life of the fabric. The use of thickener helps to control the fluidity of the glue, simplifies the coating and laminating process, and improves production efficiency. Compared with traditional adhesives, acrylic modified adhesive has lower volatile organic compound emissions and is more environmentally friendly. The addition of stearic acid helps to maintain the softness of the fabric and improve the wearing comfort of clothing made of the fabric. The use of curing agent helps to improve the stability of the fabric glue during high temperature treatment. The use of solvent helps to improve the permeability and drying speed of the glue, thereby improving the overall performance of the fabric. The above fabric glue formula enables the fabric to adapt to a wider range of application environments and conditions. The above fabric glue formula can also add various additives with a mass ratio of less than 5 as needed to enhance various required properties.

[0030] Preferably, in the above-mentioned production process of a washable and rainproof breathable reflective fabric, the water-repellent agent is one or more of amino-modified silicone oil, epoxy-modified silicone oil, polyether-modified silicone oil, carboxyl-modified silicone oil, alcohol-hydroxyl-modified silicone oil, phenol-hydroxyl-modified silicone oil, and mercapto-modified silicone oil, and the solid content of the water-repellent agent is 5% to 10%.

[0031] Using modified silicone oil as a water-repellent can significantly improve the waterproof performance of fabrics and prevent water penetration. Modified silicone oil has excellent washability, allowing fabrics to remain waterproof after multiple washes. The durability of modified silicone oil helps to increase the service life of fabrics. Water-repellent agents with a solid content of 5% to 10% can maintain the breathability of fabrics. Modified silicone oil can form a strong chemical bond with the surface of the fabric and improve the adhesion of the water-repellent agent to the fabric. The use of modified silicone oil can maintain the softness of the fabric and improve the wearing comfort of clothing made of the fabric. Modified silicone oil has anti-fouling properties, making the fabric easier to clean and reducing the adhesion of stains. Modified silicone oil helps fabrics maintain their performance during high-temperature treatment. Modified silicone oil can resist the erosion of chemicals and improve the chemical corrosion resistance of fabrics. The choice of a variety of modified silicone oils provides flexibility in production, and the formula can be adjusted as needed. BRIEF DESCRIPTION OF THE DRAWINGS
