2) According to the invention, the film layer is formed on the outer layer of the reflective yarn after low-temperature plasma treatment and immersion treatment (sodium alginate powder, glycerol and polyethylene glycol), so that the damage, peeling and falling off of glass beads on the surface of the reflective yarn can be reduced during textile processing, and the continuous protection effect is also realized in the later use process, so that the fabric has good reflective performance and is kept stable and durable, the mechanical property of the fabric can be obviously improved by using the sodium alginate, and the air permeability and moisture permeability of the fabric are not influenced;

3. Performance testing
3.1, Test of reflective Property
Washing the washed sample according to the standard program of GB/T8629-2001 household washing and drying program for textile test, adopting a horizontal rotary drum type washing machine to carry out washing test, carrying out washing test on the sample with a total load of 2kg at 40 ℃ for 18min, carrying out washing cycle times of 30 times, dehydrating for 5min after the last washing cycle is finished, and drying the sample at the temperature of (50+/-5) °.
The samples before and after washing were measured under two rotation angles of 0 ° and 90 °, respectively, under the test conditions of 12 ° observation angle, 5 ° incidence angle, and with a reflectance meter according to the specifications and requirements of standard GB 20653-2020 "high visibility warning clothing for protective clothing occupation", each group of samples was tested 6 times (3 times each under two rotation angles of 0 ° and 90 °), and the average value of the test results was recorded in table 1 below:
table 1 reflective performance test data
The experiment conclusion shows that when the undrawn masterbatch yarn is prepared, compared with zinc stearate, calcium stearate and polyethylene wax, the ethylene bisstearamide is added in a nylon 66 fiber slice and masterbatch melt mixed system, the undrawn masterbatch yarn can remarkably improve the reflective performance of the fabric and is still better after multiple times of washing, and in addition, the reflective yarn forms a film layer on the outer layer of the reflective yarn after low-temperature plasma treatment and impregnation treatment (sodium alginate powder, glycerol and polyethylene glycol), so that the damage, stripping and falling off and other conditions of glass beads on the surface of the reflective yarn can be reduced during textile processing, and the continuous protection effect is realized in the later use process, so that the reflective performance of the fabric is durable and stable.
3.2 Mechanical Property test
The samples were subjected to stress-strain testing using a dynamic mechanical analyzer model Q800 (DMA, TA instruments ltd, usa) to determine the strength and elastic modulus of the samples. The sample was cut into strips of 30 x 10mm in size and placed in a stretching jig with one end fixed and the other end movable with the jig. The temperature was maintained at 25℃and the frequency was set at 1Hz, and the applied stress was gradually increased from a value of 0 at a rate of 5MPa/s, and the strain change of the sample was recorded until the sample broke. Taking the stress at the breaking point as the tensile strength of the sample, taking the ratio of the stress to the strain at the breaking point as the elastic modulus of the sample, and testing the data as shown in Table 2:
Table 2 data for tear resistance test of fabrics
The experiment conclusion shows that the toughened reflective yarn can be obtained after the reflective yarn is subjected to low-temperature plasma treatment and immersion treatment (sodium alginate powder, glycerol and polyethylene glycol) according to the data in the table 2, so that the mechanical property of the fabric is improved, but the effect of improving the mechanical property of the fabric is less when the hydroxyethyl cellulose powder with the same quality is used for replacing the sodium alginate powder.
3.3 Test of air and moisture permeability
The sample was tested for breathability with a fully automatic breathability meter for YG461G type fabrics, with reference to the national standard (GB/T5433). The specific parameters of the experiment are set as that the ambient temperature is 23 ℃, the relative humidity is 55%, the pressure difference is l00Pa, the ventilation area is 20cm 2, the diameter of an air nozzle is 0.8mm, the fabric sample is respectively tested for 10 times at different positions, and the average value is taken as final ventilation data;
According to the national standard GB/T12704.1-2009 (a), a FX3180 type moisture permeability measuring instrument is used for moisture permeability test of a sample, wherein in the test process, the temperature is 40 ℃, the humidity is 90.0%, the air flow speed is 0.5m/s, and the test area is 25cm 2. The test chamber is pre-conditioned prior to testing. After the automatic humidity adjustment is finished, the instrument starts the moisture permeability test, and moisture permeability data are automatically recorded once every 1 hour, and the total time is two. After the experiment was completed, the moisture permeability data of the samples were manually recorded, and each group of samples had an average value of 5 groups of experimental data as final data, as shown in table 3:
table 3 fabric air and moisture permeability test data
The experimental conclusion shows that the ethylene bis-stearamide is added into a nylon 66 fiber slice and masterbatch melt mixed system, so that the air permeability and the moisture permeability of the fabric are hardly affected, and the air permeability and the moisture permeability of the fabric can be ensured by the processing technology of dipping (sodium alginate powder, glycerol and polyethylene glycol) and low-temperature plasma treatment of the reflective yarns.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
