Textile auxiliaries testing knowledge

Textile auxiliaries testing is an important part of the quality and performance evaluation of textile auxiliaries, aiming to ensure that textile auxiliaries meet relevant standards and regulations and ensure the quality and safety of textiles. The following is a detailed introduction to textile auxiliaries testing:

1. Purpose of testing
Ensure quality: Through testing, ensure that the quality of textile auxiliaries meets relevant standards and regulations and meets production and use requirements.
Evaluate performance: Evaluate the various performance indicators of textile auxiliaries, such as detergency, stability, environmental protection, etc., to provide a scientific basis for production and use.
Ensure safety: Detect the content of harmful substances in textile auxiliaries to ensure that they will not cause harm to the human body and the environment.

2. Testing items
Textile auxiliaries testing items usually include the following aspects:
Appearance and odor: Check whether the appearance of textile auxiliaries is uniform, free of impurities, and whether the odor is normal.
pH value: Determine the pH value of textile auxiliaries to ensure that they are suitable for different textile processes.
Active ingredient content: Detect the content of active ingredients in textile auxiliaries, such as surfactants, enzyme preparations, etc., to ensure that they meet the specified standards.
Stability test: Evaluate the stability of textile auxiliaries under different conditions, such as high temperature, low temperature, light, etc., to ensure that they will not deteriorate during use.
Harmful substance detection: Detect the content of harmful substances such as heavy metals, formaldehyde, volatile organic compounds (VOCs) in textile auxiliaries to ensure that they meet environmental protection and safety standards.
Biodegradability: Evaluate the ability of textile auxiliaries to be decomposed by microorganisms in the natural environment to determine their environmental protection.
Detergency test: Evaluate the cleaning effect of textile auxiliaries by simulating the washing process.
Fiber damage test: Detect the degree of damage of textile auxiliaries to textile fibers to ensure that they will not damage the textile structure during use.

3. Detection method
Textile auxiliaries detection methods usually include the following:
Chemical analysis method: Use chemical reagents and instruments to conduct qualitative and quantitative analysis of the components in textile auxiliaries.
Instrumental analysis method: Use spectroscopy, chromatography and other instruments to separate and detect the components in textile auxiliaries.
Biological experimental method: Evaluate the biodegradability and safety of textile auxiliaries through microbial experiments.
Sensory evaluation method: evaluate the appearance and smell of textile auxiliaries through visual, olfactory and other sensory means.

4. Testing agency
Textile auxiliaries testing agencies usually have professional laboratories, advanced testing equipment and experienced testing personnel. These agencies can conduct comprehensive and accurate testing of textile auxiliaries according to customer needs and industry standards. When choosing a testing agency, customers should pay attention to its qualification certification, testing scope, testing technology and service quality.
