Preface: Nonwovens test method of GB/T24218 textile products, divided into the following parts: - part 1: determination of mass per unit area; - part 2: the thickness of the determination; - part 3: determination of the breaking strength and elongation at break) (strip method; - part 5: determination of mechanical penetration resistance (ball bursting method); - part 6: determination of the absorbent; - part 8: the liquid penetrating time determination of urine (simulation); The determination of flocculant - part 10: fall; - part 11: measurement of flow capacity of; - part 12: compression absorptive determination; - part 13 : liquid many times through the determination of time; - part 14: cladding materials back to the determination of moisture content; - part 15: the determination of permeability; - part 16: the determination of water permeability resistance method (hydrostatic pressure); - section 17: the determination of water permeability (spray impact method); Part - 18: broken The determination of splitting strength and elongation at break (grab sample method); - part 101: the determination of physiological saline resistance (mason jar method). Nonwovens test method of GB/T24218 textile products, part of the above (except part 101) with that of the corresponding part ISO9073 series standard. With ISO 9073 part 4, part 7 and 9 parts corresponding to the national standard is as follows: tears --, GB/T3917.3 textile fabric performance Part 3: the trapezoid tearing strength measurement (GB/T 3917.3-2009 Textiles - Tear properties of fabrics - Part 3: Determination of tear force of trapezoid-shaped test specimens, ISO9073 - now 97, MOD); --, GB/T18318.1 textile bending performance measurement Part 1: method (GB/T 18318.1-2009 Textiles - Determination of bending behavior - Part 1: Incline method, ISO9073 - John 95, MOD); --, GB/T23329 textile fabric drapability measurement (GB/T2332 9-2009, the ruler ISO9073-08, MOD). This part is divided into GB/T24218 part 11. This section according to GB/T1.1-2009 gives the rules of the draft. This part use redraft loathsome method to modify the ISO9073-02 "textiles Test method for weaving cloth part 11: flow capacity. (English version). This section and the main differences of the loathsome ISO9073-02: - deletes the preface and introduction; --, simplifies the chapter 1; -- - the international standard of normative reference file the corresponding national standards, deleted to ISO 186 references; - increased in 2 samples of mesa Angle tolerance; - increased 4.2.5 note; - the detailed note in 4.2.6 content; --, modify the sampling method of 4.3 and 5.3; - increased in type (1) the interpretation of the alphabetic character; 12 - will note 1 in 6.5 4.5.10 into 4.5.10 and 4.5.11. This part put forward by China textile industry association. This part of the national textile standardization technical committee based norm technical committee (SAC/TC209 / SC1) under centralized. This part of the drafting unit: national spinning Woven products quality supervision and inspection center, measurement testing technology co., LTD., shenzhen China ZhongFang standard inspection certification center (Beijing) co., LTD. This part of the main draftsmen: Zhou Shixiang, clever, Zhu Ping.   
Description:The provisions of this part of GB/T24218 a quality of test liquid (simulated) in urine by nonwoven sample after absorption, overflow liquid quality measurement method.
this section can be used to compare different nonwoven sample flow capacity, but is not used for simulating the actual conditions of use of the final product.
the provisions of this part of the three different test methods:
A) method Ⅰ: basic experiment, suitable for hydrophilic nonwoven fabric;
B) method Ⅱ: repeat test method, and A) in the same test parameters;
C) method Ⅲ: small Angle test method, using with different slope in A) test rig, suitable for hydrophobic nonwoven.
