GB/T 24218 "textile non-woven fabric test method" 1 to 18 portions corresponding to ISO 9073 series of standards, in addition to the standard Registration, the other part of the correspondence with ISO 9073 as follows.

--- GB/T 3917.3 "Textiles Tear properties of fabrics - Part 3. Determination of tear force of trapezoidal shaped test specimens" (GB/T 3917.3-1997, eqv ISO 9073-4. 1989);

This section GB/T 24218 Part 6.

The partial modification of the use of ISO 9073-6:2000 "Textiles - Test methods - Part 6 Cloth non-woven. absorption measurement" (in English).

This section according to ISO 9073-6:2000 redrafted, and ISO 9073-6:2000 The main differences are as follows.

--- Scope deleted "This section does not apply to fabric containing superabsorbent material";

--- Normative references in the international standard to replace the corresponding national standards, removed the reference to ISO 186 and ISO 565;

--- The definition of the term "liquid wicking rate" is complemented;

--- Increasing the term "liquid wicking height";

--- 6.6 clear liquid wicking rate Method of seeking.

This part is proposed by the China Textile Industry Association.

This part of the National Standardization Technical Committee based textile branch (SAC/TC209/SC1) centralized.

This part mainly drafted by. Textile Standard (Beijing) Co., Inspection and Certification Center.

1 Scope

This section GB/T 24218 specifies the test method of liquid absorbing nonwoven fabric properties, including the liquid absorption time, the liquid absorbing and measured the amount of liquid wicking rate.

The measurement method of liquid absorbent nonwoven fabric may be related to the end use of the product under test.

3 Terms and Definitions

The following terms and definitions apply to this part of the GB/T 24218 of.

Liquid absorption time liquidabsorbencytime Absorption time is needed to test the liquid completely soaked material samples, that is, under specified conditions, penetration of liquids within the material needed time.

Liquid absorption liquidabsorptivecapacity LAC Under specified conditions, after a predetermined time, the liquid mass per mass of test absorbent material absorbed to account for test-absorbing material Mass percentage.

A liquid wicking rate Measure the capillary effect of the test material to characterize the liquid is transferred to the textile material speed extent that the liquid by capillary action, Per unit time in the textile material reaches a liquid wicking height.

Liquid wicking height Measure the test material when the capillary effect, namely textile end vertically suspended material is soaked in a liquid, the liquid by capillary action, in a Given time along the height of the textile material increase.
