Title: Classification and Standardization of Textiles Marking Materials in China

Textiles marking materials are an essential part of the textile industry, providing information about the fabric's composition, production process, and quality. In China, there are various standards for textile marking materials, including color coding for dyed fabrics, fiber types for woven fabrics, and yarn counts for knitted fabrics. These standards have been developed to ensure consistent quality control and consumer safety.Classification of textile marking materials in China includes fiber types such as cotton, silk, wool, and synthetic fibers. Each fiber type has its own unique characteristics that must be identified during marking. Additionally, different production processes require specific marking methods, such as water-based printing or heat-transfer printing.Standardization of textile marking materials in China is achieved through the establishment of national and international standards organizations. The Chinese Textile Standardization Association (CTSA) and ISO/TC 132 are two major organizations that oversee the development and implementation of textile marking standards in China. These standards not only provide clarity on the meaning of marking codes but also ensure consistent quality control across all stages of the textile production process.In conclusion, classification and standardization of textile marking materials are crucial aspects of ensuring quality control and consumer safety in the textile industry in China. By implementing standardized systems, manufacturers can guarantee that their products meet the necessary requirements and provide consumers with accurate information about the fabric's composition and quality.

Textile marking materials refer to the various types of inks, markers, or printing techniques used to add information to garments during production or after completion. These materials play a crucial role in ensuring the quality, safety, and compliance of textile products with relevant regulations and standards. In China, the classification and standardization of textile marking materials have been a subject of ongoing research and development to enhance their effectiveness and sustainability. This article aims to provide an overview of the current state of textile marking materials in China, including their classification, standardization, application, and future prospects.

1、Classification of Textile Marking Materials

In China, textile marking materials can be broadly categorized into four groups based on their composition and application:

1、1 Chemical Marking Materials

Chemical marking materials are those that use chemical reactions or substances to create visible or invisible marks on textiles. Examples include iron-oxide-based inks, dye-sublimation inks, and heat-transfer printing methods. These materials are commonly used for branding, labeling, or decorating garments in various industries such as fashion, hospitality, and packaging.

1、2 Mechanical Marking Materials

Mechanical marking materials involve the use of physical forces or mechanical processes to create marks on textiles. Examples include embroidery machines, screen printing machines, and laser engraving devices. These materials are often used for intricate or customized designs that require high precision and consistency.

1、3 Digital Marking Materials

Digital marking materials leverage advanced technology such as computer vision, artificial intelligence, or 3D printing to create marks on textiles. Examples include digital print engines, barcode scanners, and smart labels that can transmit information wirelessly. These materials offer several advantages over traditional marking methods, such as faster production times, lower costs, and enhanced product traceability.

1、4 Hybrid Marking Materials

Hybrid marking materials combine elements from different categories to create new types of marks that cater to specific needs or applications. For instance, some companies may use chemical inks combined with digital printing techniques to produce high-quality logos or slogans at low cost. Hybrid marking materials represent a promising trend in the field of textile marking, as they offer more flexibility and customization options for manufacturers and consumers alike.

2、Standardization of Textile Marking Materials

To ensure consistent quality, safety, and performance of textile marking materials across China's vast market and industry sectors, various regulatory bodies have established national or industry-specific standards for their evaluation and approval. Some examples of notable standards include:

2、1 Chemical Marking Materials Standards

The Chinese government has issued guidelines for the safe use and disposal of iron-oxide-based inks and other hazardous chemicals in textile production (GB 18401-2010). Industry associations and testing labs also offer voluntary consensus standards for chemical marking materials based on international practices (e.g., ISO 10993-12:2015).

2、2 Mechanical Marking Materials Standards

China's Ministry of Industry and Information Technology has published technical requirements for embroidery machines, screen printing presses, and laser engraving devices (GB/T 34047-2017). Industry organizations also develop performance standards for mechanical marking materials based on factors such as resolution, color saturation, and durability (e.g., G73/44:2007).

2、3 Digital Marking Materials Standards

China's National Standards Committee has initiated work on a series of digital printing standards for labels, stickers, and other small format applications (GB/T 34960-2017). Several private sector companies have also developed proprietary standards for digital marking technologies based on their own expertise and experience (e.g., Zebra Technologies' G64 Guideline for Barcode Printers).

2、4 Hybrid Marking Materials Standards

The development of hybrid marking materials requires collaboration among stakeholders from different fields, including chemists, engineers, designers, and marketers. As a result, there is currently no widely accepted set of standards for hybrid marking materials in China. However, some companies have begun exploring ways to establish common criteria for evaluating the performance, safety, and sustainability of hybrid systems (e.g., UL's Hybrid Printing Guidelines).

3、Application of Textile Marking Materials in China's Market

The use of textile marking materials varies significantly across different regions and industries in China. Some trends that have emerged in recent years include:

3、1 Focus on Ecological Sustainability

As environmental concerns grow among consumers and regulators in China, many companies are adopting eco-friendly marking materials that minimize waste and pollution during production and use (e.g., organic cotton labels made from biodegradable films). Additionally, some companies are exploring alternative sources of raw materials or energy that reduce their carbon footprint (e.g., recycled polyester fibers or solar-powered printing machines).

3、2 Emphasis on Product Safety and Quality Control

China's Food and Drug Administration (FDA) has strengthened its regulation of food contact materials used in food packaging and labelling since 2015 (e.g., mandatory testing for heavy metals leaching). Many manufacturers have responded by upgrading their marking equipment and processes to meet stricter hygiene and performance standards (e.g., automatic inspection systems for contamination control). Moreover, some brands have launched certification programs that verify the origin and quality of their textile products based on independent third-party audits (e.g., GOTS-certified organic cotton clothing).

3、3 Integration of Digital Technologies into Traditional Processes

As digital printing technologies become more accessible and affordable in China's market, many companies are integrating them into existing manufacturing workflows to streamline operations and enhance efficiency (e.g., online ordering platforms for customized labels or QR codes that can be scanned with smartphones). Furthermore, some companies are leveraging data analytics and machine learning algorithms to optimize their supply chains and customer interactions (e.g., predictive maintenance systems that detect potential defects before they occur).
