Foreword
The standard proposed by China Textile Industry Association.
This standard by the National Standardization Technical Committee on Basic Standards Subcommittee Textiles (SAC/TC209/SC1) centralized.
This standard is mainly drafted by. Textile Standard (Beijing) Co., Inspection and Certification Center.
The main drafters of this standard. Zhou Shixiang.
Determination of anti-ethanol solution properties of textiles
1 Scope
This standard specifies the wetting and surface tension of different series of standard test solution for testing and evaluation of anti-textile ethanol and other organic solvents
Standard Test Method for Performance of penetration.
This standard applies to all textile fabrics.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. Undated document, the latest versions apply to this standard.
GB/T 6529 Textiles conditioning and testing using standard atmosphere (GB/T 6529-2008, ISO 139.2005, MOD)
3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
The highest number of stages within the specified time, so that the fabric is not wetting/penetration of the respective aqueous ethanol.
Principle 4
Using aqueous ethanol having different surface tension of test solution consisting of a series of standards, the test specimen surface in dropwise, within a certain time,
Observe the standard test solution droplets wetting and penetration of the surface of the sample, and to determine the anti-alcohol levels.
5 Safety Precautions
5.1 ethanol, methanol, isopropanol, and other organic solvents are toxic, especially toxic methanol, and may cause a fire. Laboratory should have
Appropriate security protection, such as proper ventilation or protective mask.
5.2 In dealing with the liquid, should wear protective gloves and safety goggles or protective goggles.
5.3 Do not tested in an open flame or other sources of ignition exist.
6 equipment, reagents and materials
6.1 Ethanol, a chemical alcohol.
NOTE. The parties agree that other agents may be methanol, isopropanol and the like be used.
6.2 deionized or distilled water.
6.3 dropper capacity of 60mL, with a plastic head dropper.
6.4 filter.
6.5 routine laboratory use gloves.
6.6 preparation of standard test solution according to Table 1, and indicate the appropriate number of levels.
