Problems solved by technology

However, nano-compounds are inorganic substances, and textiles are organic substances. How to realize the combination of inorganic and organic is a technical problem. How about their combination fastness? How to detect? At present, scanning electron microscopy, scanning tunneling electron microscopy, atomic force microscopy, photoelectron spectroscopy, and X-ray diffraction are generally used to analyze the microstructure of nanotextiles (see literature: Li DP, Sun G., Dyes and Pigments 2007; 72:144), The above analysis means can qualitatively characterize the type, shape, distribution and surface element content of nanomaterials on textiles. However, the testing instruments used are expensive and are rarely used by enterprises except for scientific research and professional testing units. Ordinary It is impossible for consumers
In addition, what these instruments test is the characterization of local microscopic nanomaterials in textiles, which cannot macroscopically reflect the appearance of nanomaterials and the distribution and fixation of nanomaterials on textiles.

Embodiment 1

[0022] Cotton fabric containing nano-zinc oxide (32 combed cotton, 110g / m 2 ) According to the Chinese national standard GB8629-2001 (household washing and drying procedures used in textile experiments), the washing methods are respectively washing 0 times, 10 times, 20 times, and after drying, the obtained samples and control samples are cut into 3cm The shape of ×2cm is marked as A0, A10, and A20 respectively, and the textile without nanomaterials is selected as the blank control sample, and the control sample is marked as A.

[0023] Put the control sample A into the muffle furnace. When the temperature rises to 1100°C, A is completely burnt out, and 1100°C is determined to be the effective temperature of the test. Then, put A0, A10, and A20 in sequence and raise the temperature to 1100°C In the muffle furnace, take out the sample when the fibers are completely burnt out, take pictures with a digital camera, observe the morphology of the residue, and measure the area and we...

Embodiment 2

[0028] Cotton knitted fabric containing nano-titanium dioxide (21 combed cotton, 135g / m 2 ) According to the Chinese national standard GB8629-2001 (household washing and drying procedures used in textile experiments), wash 0 times, 20 times, after drying, cut the obtained samples and control samples into the shape of 5cm×3cm, respectively marked as B0 , B20, mark the control sample as B. Put the control sample B into the outer flame of the alcohol lamp and burn it. After 1 minute, the control sample B is completely burned to confirm that the burning test of the alcohol lamp is effective. Then put B0 and B20 into the outer flame of the alcohol lamp and burn it until the fibers are completely burned. Remove the sample, take pictures with a digital camera, observe the morphology of the residue, and measure the area and weight of the residue at the same time. The results are shown in Table 2.

Embodiment 3

[0034] The silk fabric containing nano iron oxide (100% mulberry silk, 85g / m 2 ) According to the Chinese national standard GB8629-2001 (household washing and drying procedures used in textile experiments), wash 0 times, 20 times, and cut the obtained samples and control samples into 3cm×2cm shapes after drying, respectively marked as C0 , C50, the control sample is marked as C. Put the control sample C into the muffle furnace. When the temperature rises to 1000°C, C is completely burned out, and 1000°C is determined as the effective temperature of the test, and then put C0 and C50 into the muffle furnace with the temperature raised to 1000°C in turn. In the furnace, take out the sample when the fibers are completely burned out, take pictures with a digital camera, and measure the area and weight of the residue at the same time.

[0035] Table 3 shows the morphology, area and weight of the residue after washing and calcining the silk fabric containing nanometer iron oxide for...

Abstract

The invention discloses a method for judging an inorganic nanometer material on a textile. By utilizing the method, simple and effective identification on the existing condition and combination firmness of the inorganic nanometer material on the textile is realized by utilizing the characteristics of high-temperature resistance of the inorganic nanometer material and non high-temperature resistance of a natural textile through a burning method according to the color, distribution and firmness of the nanometer material remained on the textile. In the detection method, special equipment is not needed; and the detection method can be used for detecting the inorganic nanometer materials on a plurality of textiles, has the advantages of generality, portability, high efficiency and environmental friendliness.

Description

technical field [0001] The invention relates to a method for quickly judging inorganic nanometer materials on textiles, which can be used to detect nanometer materials, distribution and fixation properties in textiles. Background technique [0002] As one of the three major industries in the 20th century, nanotechnology has attracted widespread attention from the scientific and technological circles and industrial circles all over the world due to its broad application fields, diversity of additional functions and convenient application methods, and has become the current international One of the cutting-edge research topics in the world. The textile field is a bridge for nanotechnology to enter the lives of ordinary people. Nanotechnology has also officially entered the traditional textile industry.
