Test method for water repellency of synthetic staple fibers

1 Scope

This document specifies a test method for the water repellency of synthetic staple fibers. This document applies to synthetic staple fibers. Note. Short fibers with water-repellent properties generally include. polyethylene (PE)/polypropylene (PP) composite staple fibers, polyethylene (PE)/polyester (PET) composite staple fibers Dimension, polyethylene terephthalate (PET) short fiber, etc.

2 Normative references

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to this document.

3 Terms and Definitions

The terms and definitions defined in GB/T 4146 (all parts) and the following terms and definitions apply to this document. 3.1 Slippage topsheetrun-off The volume that is not absorbed when a certain amount of test solution flows over the surface of an inclined specimen. [Source. GB/T 28004-2011, 3.1] 3.2 airlaidpaper Dry-laid nonwovens Non-woven fabrics are produced from wood pulp fibers by air-laid technology and thermal bonding process; they have extremely high water absorption and good stability. Good water retention properties.

4 Principles

Under the specified conditions, the solution obliquely flows through the surface of the fiber sample, and the water-repellent performance is indirectly characterized by the amount of slippage. The better the water repellency Fiber, after the solution flows through, the less the amount of absorption, the more the amount of slippage.

5 Instruments and tools

5.1 Roller Fiber Extender The distance between the feeding roller and the feeding roller is 16mm~60mm.
