Description:A METHOD FOR PREPARATION OF ECO-PRINTING BASED HAND-SPUN GREWIA OPTIVA TEXTILES

FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of sustainable and eco-friendly textile designs and production, specifically, a method for preparation of eco-printing based hand-spun Grewia optiva textiles.

BACKGROUND

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] The textile industry, while being one of the largest global industries, faces significant challenges related to environmental sustainability, resource consumption, and the preservation of traditional craftsmanship. Conventional textile production methods rely heavily on synthetic dyes, chemical treatments, and industrial-scale processes that contribute to pollution, excessive water consumption, and depletion of natural resources. Additionally, mass-produced textiles often overshadow indigenous and hand-spun fabric traditions, leading to a decline in traditional handloom practices. The lack of innovation in integrating eco-friendly processes into traditional textile production further exacerbates the situation, making it difficult for sustainable alternatives to compete in modern markets. The demand for environmentally friendly textile production methods has grown in recent years, but the industry continues to struggle with finding scalable solutions that do not compromise on sustainability, aesthetics, or cultural significance.
[0004] In an attempt to mitigate the environmental impact of textile production, various solutions have been explored, such as the use of organic cotton, natural dyeing techniques, and recycled textiles. Eco-printing, a relatively new technique, has gained some traction in sustainable fashion and textile production, allowing for the transfer of botanical pigments onto fabric without synthetic chemicals. However, these solutions often target commercially available, machine-made textiles rather than hand-spun or indigenous fabrics. Additionally, while natural dyeing methods reduce chemical pollution, they may not always provide long-lasting colour retention or the desired visual appeal required by consumers. Existing sustainable textile solutions also lack a holistic approach that integrates not only ecological benefits but also economic empowerment for artisans. This results in a market gap where truly sustainable, aesthetically appealing, and culturally relevant textile solutions remain limited.

[0021] The present invention discloses a method for preparation of eco-printing based hand spun Grewia optiva textiles. The method produces eco-friendly, durable, and aesthetically appealing textiles using natural materials and sustainable processes.
[0022] FIG. 1 illustrates a flow chart of a method for preparation of eco-printing based hand-spun Grewia optiva textiles, according to an embodiment of the present invention.
[0023] In some embodiments, Grewia optiva based fabric is prepared using hand-spun Grewia optiva fibres, at step 102. The Grewia optiva fibres are extracted from the bark of the Grewia optiva plant which is naturally found in the Himalayan regions. The Grewia optiva fibres are carefully separated from the plant and are processed manually to remove unwanted residues, dust and other impurities while maintaining strength and texture properties of the Grewia optiva fibres. Once cleaned, the Grewia optiva is woven by using hand spinning process that utilizes traditional spinning techniques to create yarns suitable for weaving fabric. The spinning is carefully controlled to produce uniform and consistent yarn thickness.
[0024] The hand spun Grewia optiva fibres are woven into a Grewia optiva fabric using traditional weaving techniques. The weaving of Grewia optiva fabric is performed manually on handlooms by skilled artisans. The weaving pattern is selected with careful consideration to ensure that the Grewia optiva fabric is conducive to eco printing while maintaining the desired strength, flexibility and durability of the textile. The selection of weaving techniques ensures that the Grewia Optiva fabric maintains optimal porosity, which allows it to absorb botanical pigments efficiently during the eco-printing process.
[0025] Natural botanical materials are selected for eco printing that contain rich and vibrant natural pigments. The natural botanical materials comprise flowers, leaves or roots of eucalyptus leaves, indigo plants, and marigold flowers that are rich in natural dyes and pigments. Natural botanical materials such as eucalyptus leaves, indigo plants, and marigold flowers are rich sources of natural dyes and pigments, widely used in sustainable textile dyeing, cosmetics, and medicinal applications. Eucalyptus leaves contain tannins and flavonoids, producing shades of brown, green, and yellow. Indigo plants (i.e., Indigofera tinctoria) are renowned for their deep blue pigment, derived from indican, which converts to indigo through oxidation. Marigold flowers (i.e., Tagetes spp.) are abundant in carotenoids like lutein, yielding vibrant yellow to orange hues. These plant-based dyes offer an eco-friendly alternative to synthetic dyes, providing biodegradable, non-toxic, and skin-friendly coloration while promoting sustainable practices in various industries. The natural botanical materials are chosen for their ability to create intricate and aesthetically unique patterns on the surface of the Grewia optiva fabric. The botanical material is selected based on their pigment characteristics.
[0026] In some embodiments, the Grewia optiva fabric is pre-treated with at least one natural mordant to enhance dye absorption, at step 104. The woven Grewia optiva fabric undergoes a comprehensive pre-treatment process utilizing at least one natural mordant. The natural mordant comprises tannin, iron, alum or plant based mordant selected based on the desired colour and fabric composition. A natural mordant is a substance that enhances the bonding of natural dyes to fabrics, improving color fastness and intensity. Common natural mordants include tannin, iron, and alum, as well as plant-based alternatives. Tannin is found in plants like oak galls, myrobalan, and pomegranate peels, binds well with proteins and cellulose, making it an excellent pre-mordant for deep, rich colors. Further, Iron (i.e., ferrous sulfate) darkens hues and creates muted, earthy tones, often used for modifying shades of natural dyes. Further, Alum (i.e., potassium aluminum sulfate) is a widely used, non-toxic mordant that brightens colors and improves dye absorption. Other plant-based mordants, such as rhubarb leaves, sumac, and tea is configured to provide additional eco-friendly options, reducing reliance on synthetic chemicals while ensuring vibrant and long-lasting natural dyeing results.
[0027] The at least one natural mordant are applied to the Grewia optiva fabric in a controlled environment to ensure even and uniform distribution across all the surfaces of the Grewia optiva fabric. The pre-treatment process enhances the ability of the Grewia optiva fibres to bond with the pigments of botanical material to ensure long lasting colour retention and durability. The process further ensures that the Grewia optiva fabric fibres maintain structural integrity while facilitating an optimal surface for eco printing.
[0028] In some embodiments, the botanical materials are arranged on a surface of the pre-treated Grewia optiva fabric to create patterns, at step 106. The botanical materials are selected based on their natural pigment content for higher colour vibrancy and adherence. The botanical materials undergo cleaning and preparation process to remove impurities, moisture or residue that might hinder the optimal pigment transfer.
[0029] The prepared botanical materials are carefully arranged on the surface of the Grewia optiva fabric in patterns. The placement of the botanical materials determines the final pattern that appears after the eco printing process. Each arrangement is unique and ensures that every eco-printed Grewia optiva fabric exhibits non-replicable and nature inspired patterns. The variation in pattern formation contributes to the exclusivity and artistic appeal of the final textile.
[0030] In some embodiments, the Grewia optiva fabric is rolled and wrapped with the arranged botanical materials, at step 108. After arranging the botanical materials in the desired configuration, the Grewia optiva fabric is tightly rolled and wrapped to secure the botanical materials in position. The rolling process begins from one end of the Grewia optiva fabric, with consistent pressure applied to ensure that the botanical materials remain in uniform contact with the Grewia optiva fabric surface. The rolling is carefully performed to prevent displacement of the botanical materials during subsequent processing.
[0031] Further, the rolled Grewia optiva fabric is then wrapped securely using a wrapping material that is specifically chosen to withstand the conditions of the steaming processes. The wrapping material is selected based on its ability to allow sufficient heat and moisture transfer while maintaining the integrity of the botanical materials throughout the steaming phase. The secure wrapping may ensure that the botanical materials remain firmly pressed against the Grewia optiva fabric to facilitate the optimal transfer of natural pigments and ensuring the formation of well-defined eco printed patterns.
[0032] In some embodiments, the wrapped Grewia optiva fabric is steamed to transfer natural pigments from the botanical materials to the Grewia optiva fabric, at step 110. The steaming process facilitates the absorption of botanical pigments into the Grewia optiva fabric for the formation of natural intricate patterns that are permanent and vibrant.
[0033] The wrapped Grewia optiva fabric is subjected to a controlled steaming process that facilitate the release and transfer of natural pigments from the botanical materials to the Grewia optiva fabric. The steaming process is carried out under regulated temperature and humidity conditions to ensure uniform pigment absorption across the entire surface of the Grewia Optiva fabric. The steam deeply penetrates the multiple layers of the wrapped Grewia optiva fabric, initiating the breakdown of the natural pigments in the botanical materials and allow them to infuse into the pre-treated Grewia optiva fabric, enhancing the natural dye uptake and ensuring a well-defined long lasting unique patterns.
[0034] The duration and temperature of the steaming process are carefully optimized based on the botanical materials used and the required intensity of the final patterns. The steaming process is performed for a specific time frame that allows maximum pigment transfer without over-processing, ensuring that the natural colours remain rich and do not fade prematurely. Further, the steaming process may ensure that the natural pigments bond effectively with the mordant-treated Grewia optiva fabric fibres, thereby producing deeply embedded and visually striking patterns that are resistant to fading and washing.
[0035] In some embodiments, the Grewia optiva fabric are rinsed and dried to obtain an eco-printed textile, at step 112. After the completion of the steaming process, the wrapped Grewia optiva fabric is carefully unwrapped, and the botanical materials are removed from the surface of the Grewia optiva fabric. The removal process ensures that no plant residues remain adhered to the fabric, preserving the clarity and definition of the eco-printed patterns. The Grewia Optiva fabric is then subjected to a thorough rinsing process to eliminate any excess pigments, botanical fragments, or mordant residues that may have remained on the fabric surface.
[0036] The rinsing process is performed using clean, temperature-controlled water to prevent any unnecessary fading or bleeding of the transferred botanical patterns. The rinsing technique ensures that the natural pigments remain securely embedded within the fibres of the Grewia optiva fabric in order to preserve the vibrancy and durability of the patterns. To maintain the eco-friendly nature of the process, minimal water usage techniques are employed in order to ensure sustainability without compromising the quality of the final product.
[0037] Further, the rinsed Grewia Optiva fabric is subsequently dried under carefully controlled conditions to ensure that the eco-printed patterns are preserved in their most vibrant and intricate form. The drying process is performed using natural air-drying methods, as excessive mechanical drying may compromise the structural integrity of the Grewia Optiva fabric. The fabric is spread out in a well-ventilated, shaded area to allow for gradual moisture evaporation, preventing any distortion or unwanted fading of the botanical prints. By employing natural drying techniques, the process remains environmentally sustainable while ensuring that the final Grewia Optiva textile retains its softness, durability, and uniquely crafted aesthetic appeal.
[0038] In some embodiments, a softener is applied to the Grewia optiva fabric. A suitable softener that is compatible with the inherent properties of the Grewia optiva fabric is carefully selected, at step 114. The softener retains the natural durability and structural integrity. Further, the softener may correspond to silicon softener. A silicon softener is applied to the Grewia optiva fabric. The silicon softener improves the overall hand feel and draping qualities of the eco-printed textile. The silicon softener forming a thin, flexible coating on the Grewia optiva fabric, thereby reducing surface friction and imparting a smooth, soft texture. The application of the silicon softener makes the fabric suitable for various applications in fashion and home textiles. The silicon softener is applied in controlled quantities in order to achieve desired softness without compromising the eco-printed patterns or the natural characteristics of the Grewia optiva fabric.
[0039] The method results in eco-friendly, durable, and aesthetically appealing Grewia optiva textiles with unique, non-replicable patterns. The eco-printing process ensures that each eco-printed hand-spun Grewia optiva textile exhibits a distinct design influenced by the natural pigment variations of the botanical materials. Additionally, the method eliminates the need for synthetic chemicals, thereby reducing environmental impact and promoting sustainable textile production. The structural properties of the Grewia optiva fabric combined with the botanical-based printing technique to enhance the longevity and market value of the final product. The use of natural mordant, botanical materials, and silicon softener may ensure that the method has minimal environmental impact. The water usage in the process is optimized at each step to conserve resources while achieving the desired results.
[0040] In an alternative embodiment, the eco-printed hand-spun Grewia optiva textiles are produced using a combination of synthetic dyeing and printing methods. The Grewia optiva fabric after weaving from hand-spun Grewia optiva fibres is subjected to screen printing or digital printing processes. The synthetic dyes are applied to the Grewia optiva fabric using specialized printing equipment that enables precise pattern reproduction. The printed Grewia optiva fabric undergoes heat setting and curing processes to fix the synthetic dyes. The finished Grewia optiva textiles exhibit vibrant colours and precise patterns but lack the unique, non-replicable characteristics achieved via natural eco-printing processes.
[0041] In an alternate embodiment involves the application of conventional eco-friendly dyeing techniques to the hand-spun Grewia optiva textiles. The Grewia optiva fabric is dyed using natural dye extracts without employing the eco-printing technique. The natural dyes are extracted from various plant sources and applied to the Grewia optiva fabric using traditional immersion dyeing methods. The Grewia optiva fabric is pre-treated with natural mordant to ensure colour fastness. The dyeing process creates uniform coloration across the Grewia optiva fabric surface, but without the intricate patterns characteristic of eco-printing. This embodiment maintains environmental sustainability while offering simpler production processes.
[0042] In one another embodiment, the eco-printing process is applied to machine-made sustainable fabrics instead of hand-spun Grewia optiva textiles. The base fabric is manufactured using industrial processes from sustainable fibres such as organic cotton, hemp, or bamboo. The machine-made fabrics undergo the same eco-printing process, including pre-treatment with natural mordant, arrangement of botanical materials, rolling, wrapping, and steaming. The finished products demonstrate the aesthetic appeal of eco-printing but lack the unique textural characteristics and cultural significance of hand-spun Grewia optiva fabrics.
[0043] In an another alternate embodiments eco-printing process is replaced with traditional hand-painting or block printing techniques applied to hand-spun Grewia optiva textiles. The Grewia optiva fabric is decorated using natural pigments applied via hand-painting or carved wooden blocks. The process involves preparing natural pigments from botanical sources and applying them directly to the mordant Grewia optiva fabric. The finished Grewia optiva textiles feature repeatable patterns that lack the subtle variations and impressions characteristic of botanical contact printing.
[0044] In a yet other embodiment, digital printing technology is utilized with eco-friendly inks to create patterns on hand-spun Grewia optiva textiles. The Grewia optiva fabric is processed using digital textile printers equipped with water-based, eco-friendly inks. The method produces precise pattern reproduction and complex design capabilities. The printing process is computer-controlled, allowing for consistent pattern reproduction across multiple pieces of Grewia optiva fabric. The finished Grewia optiva textiles exhibit high-quality prints but miss the authentic, nature-derived characteristics of eco-printed fabrics.
[0045] It should be noted that the method (100) of preparation of eco-printing based hand spun Grewia optiva textiles in any case could undergo numerous modifications and variants, all of which are covered by the same innovative concept; moreover, all of the details can be replaced by technically equivalent elements. In practice, the components used, as well as the numbers, shapes, and sizes of the components can be of any kind according to the technical requirements. The scope of protection of the invention is therefore defined by the attached claims.
