Understanding Environmental Standards and Certifications
The first step in selecting environmentally friendly textile auxiliaries is understanding the relevant environmental standards and certifications. Internationally, Oeko-Tex Standard 100 is a well-known eco-safety certification for textiles, which strictly limits harmful substances in textile auxiliaries. Domestically, standards such as GB 18401, the "National Basic Safety Technical Specifications for Textile Products," stipulate limits on harmful substances such as formaldehyde, pH value, and decomposable aromatic amine dyes in textile products. Choosing textile auxiliaries with these authoritative certifications ensures their environmental friendliness from the source. For example, auxiliaries certified with Oeko-Tex Standard 100 pose less harm to the environment and human health during production and use, and can be safely used in textile processing.

Examining Ingredients and Formulations
Carefully reviewing the ingredient list of textile auxiliaries is crucial. Avoid auxiliaries containing heavy metals (such as lead, mercury, cadmium, etc.), formaldehyde, halogenated hydrocarbons, volatile organic compounds, and other harmful substances. Prioritize auxiliaries made from natural and renewable raw materials, such as plant extracts and bio-based materials. Simultaneously, pay attention to the simplicity of the auxiliary formulation; excessive chemical additives may increase environmental burden and health risks. For example, some new environmentally friendly softeners use natural oils and plant extracts as their main components, offering not only excellent softening effects but also environmental friendliness.

Evaluating Performance and Stability
Environmentally friendly textile auxiliaries must not only be environmentally friendly but also possess good performance and stability. While meeting environmental requirements, examine whether they achieve the expected processing results. For example, dyeing auxiliaries should ensure uniform dyeing and high color fastness; finishing auxiliaries should give textiles a good hand feel and wrinkle resistance. Furthermore, the stability of auxiliaries under different processing conditions is also crucial. Stable performance can reduce waste and defect rates during production, indirectly reducing environmental impact.
