Issued by the Ministry of Industry and Information Technology of the People 's Republic of China
Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard is modified using ISO 17608..2015 "Textile bare rubber fiber resistance to chlorinated water (swimming pool water) performance test".
The main differences between this standard and ISO 17608..2015 are as follows.
--- the normative reference document in the international standard replaced by the corresponding national standards;
- the normative reference documents to increase the relevant national standards and industry standards;
- Terminology and definition of the definition of elastic fibers to be replaced by GB/T 4146.1 "Textiles Chemical fibers Part 1.
Name ";
- a detailed description of the instrument and utensil to cancel the isokinetic elongation strength machine, instead of referring to the FZ/T 50006 "spandex
Tensile properties test method ";
- Increased sampling requirements in the test general;
- a detailed description of the elimination of the rupture test in the test procedure, instead of quoting the FZ/T 50006 "spandex yarn tensile test
method".
This standard is proposed by China Textile Industry Federation.
This standard is under the jurisdiction of Shanghai Textile Industry Technical Supervision.

3 terms and definitions
The following definitions and definitions as defined in GB/T 4146.1 and GB/T 4146.3 apply to this document.
3.1
Breaking strength retention
The ratio of the breaking strength after the treatment under specified conditions to the breaking strength before treatment is expressed as a percentage.
4 principle
Uncoated spandex filament in a certain concentration of chlorine solution after immersion, by the impact of active chlorine, fiber physical properties have changed.
The strong retention rate of spandex filament is used to characterize the chlorine resistance of spandex filament.
5 instruments and appliances
5.1 Mechanical devices
A suitable mechanism consists of a water bath with a rotating shaft. Rotation axis is radially supported by more than the capacity of about
550mL ± 50mL, 75mm ± 5mm in diameter, high 125mm ± 10mm stainless steel containers, containers can be sealed to seal. Rotate
The distance from the center of the shaft to the bottom of the container is 45 mm ± 10 mm. Rotation axis and container assembly speed of 40r/min ± 2r/min. Water bath temperature
Degrees controlled by the thermostat, keep the set temperature within ± 2 ℃.
Note. Other devices that can achieve the same effect can also be used.
