GB/T 24253-2009 Textiles - Evaluation for anti-mites activity
Textiles - Evaluation for anti-mites activity
1 Scope
This standard specifies the test and evaluation methods of anti-mites activity of textiles using repellent method and inhibition method.
This standard is applicable to all kinds of textile products, including down feather, fiber, yarn, fabric and products. The repellent method is applicable to all textile products; and the inhibition method is applicable to products that are not washed frequently, e.g. padding (cotton wool, down feather, etc.) and carpets.
The evaluation of the safety of anti-mites products is not covered by this standard.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply to this standard. However parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
GB/T 12490-2007 Textiles - Tests for colour fastness - Colour fastness to domestic and commercial laundering (ISO 105-C06:1994, MOD)
3 Terms and definitions
For the purposes of this standard, the following term and definition apply:
3.1
mites
a kind of tiny animal with spherical or elongated body, belonging to arthropoda, arachnoidea and order acari, with the basic structure of the polypide consisting of gnathosoma and idiosoma, with four pairs of feet for adult and nymph and three pairs of feet for larva
Note: Mites in this standard are dust mites capable of causing allergic reactions in humans.
3.2
anti-mites activity
performance of the product to repel mites or inhibit the growth and reproduction of mites
3.3
control sample
material used to verify the test mite growth conditions which is made of the same material as the specimen but without anti-mite finishing or, if necessary, is 100% cotton fabrics without any treatment, steamed and boiled at high temperature and washed with distilled water
Note: It’s proved that the standard cotton adjacent fabric for color fastness test is suitable as a control sample after being steamed and boiled at high temperature and washed with distilled water.
4 Safety precautions
Mites can easily spread under test conditions and pose a hazard to the test personnel or others, so the test shall be conducted by trained personnel in a defined test environment.
