Description
Technical field
The present invention relates to the method for testing of a kind of fabric and goods colour fastness thereof, be adapted to different components, the colour fastness method of testing of the textile of different tissues and goods thereof and all kinds of nonwoven fabrics and goods thereof.
Background technology
Ecology, environmental protection, safe textile receives people's concern day by day, relevant rule and standard oko-Tex 100 and GB18401 have been put into effect in succession with China in Europe, comprised colorfastness to rubbing, PERSPIRATION COLOR FASTNESS and saliva colour fastness, but do not consider this index of urine stain colour fastness.Underwear and children's clothing infant clothing especially when wearing often can be infected with urine, and urine is with after textile/clothes contact, through uniform temperature and pressure condition, meeting and dyestuff generation chemical reaction extract to such an extent that dyestuff can be absorbed by the body by skin, and health is damaged; Simultaneously, the original color of clothes is changed, affect its appearance effect.Based on above reason, the urine colour fastness of textile/clothes and correlated product is particularly important for improving Product Safety.And in present existing domestic and international testing standard, for this problem, also do not have concrete method of testing.Restrict like this quality of production management and product control level, also affected the quality supervision work of correlated quality department simultaneously.
Summary of the invention
Purpose of the present invention just provides a kind of method of testing of urine stain colour fastness, can be adapted to different components, the textile of different tissues and goods thereof and all kinds of nonwoven fabrics and goods thereof.Urine stain colour fastness method of testing of the present invention has been filled up the blank of domestic and international this technical field, comprising the configuration of urine solution, and the method that test procedure and result pass judgment on.
The concrete technical scheme that the present invention takes is as follows:
The method of testing of urine stain colour fastness may further comprise the steps:
A, configuration urine reagent and preparation specimen;
B, place urine reagent to soak specimen;
C, remove urine reagent unnecessary on the specimen after, with its concora crush;
D, the specimen that will still be in the concora crush state are placed appropriate time under preference temperature, then take out specimen, launch and at the air drying that is no more than 60 ℃;
E, with the staining of the multifilament adjacent fabric that adheres on the variable color of ISO gray scale evaluation specimen and the specimen.
The proportioning of urine reagent can be by following operation among the above-mentioned steps a: contain in per 1 liter of urine reagent
A. urea 30-40g
B. sodium chloride 13-18g
C. strong phosphoric acid 2-5ml
D. concentrated sulphuric acid 1-5ml
E. calcium phosphate 1-5g
F. strong aqua 5-10ml
G. concentrated hydrochloric acid 1-5ml
All the other are water.
The mass concentration that the mass concentration that the optional chemical detection of the concentration of said phosphoric acid, sulfuric acid and ammoniacal liquor experiment concentration value commonly used among the present invention, the mass concentration of phosphoric acid are preferably 75%-85%, sulfuric acid is preferably 70%-98%, concentrated hydrochloric acid is that the mass concentration of 35%-37%, ammoniacal liquor is preferably 25%-28%.The content of each composition is preferably urea 35.0g in the urine reagent, sodium chloride 16.5g, phosphoric acid 3.0ml, sulfuric acid 2.0ml, calcium phosphate 1.2g, hydrochloric acid 3.0ml, ammoniacal liquor 6.5ml.
Among the above-mentioned steps a, specimen generally is to get 40mm * 100mm fabric to be measured or its goods one, and the front also contacts with the multifilament adjacent fabric of a 40mm * 100mm simultaneously, sews up along a minor face, forms a composite sample.
Among the above-mentioned step c, specimen can be flat on it between two blocks of glass or the acrylic resin plate, is placed on pressurized in the test unit of preheating.The pressure limit that fabric and goods thereof may be subject to when using according to human body or infant is chosen a suitable pressure, as selected between 5-15kPa all be feasible.
Above-mentioned steps d, said preference temperature refers to the environment temperature of fabric or its goods, and is near the body temperature of human body, the most suitable beyond doubt as probe temperature at 37 ℃ ± 2 ℃ so when generally using as finished product.Temperature retention time can be 4-18 hour scope in 37 ℃ ± 2 ℃ baking oven for the specimen of concora crush, and substantially dry during taking-up is so it is just passable to place 1-2h after launching in being no more than 60 ℃ air.
Beneficial effect of the present invention: the method for testing of urine stain colour fastness provided by the invention, simple and easy to do, can be adapted to different components, the textile of different tissues and goods thereof and all kinds of nonwoven fabrics and goods thereof.Urine stain colour fastness method of testing of the present invention has been filled up the domestic and international technological gap in this field.Restrict quality of production management and product control level, also affected the quality supervision work of correlated quality department simultaneously.
