Performance test
Detection method
Taking the wearable and washable shea butter modified composite fabric obtained in examples 1-18 and comparative examples 1-2, weighing the fabric with the mass of W1, placing the fabric in a beaker, adding absolute ethyl alcohol with the weight being five times that of the fabric, extracting for 72 hours at a constant temperature of 80 ℃ in a water bath to obtain an extract, performing an absorbance test on the extract at a fixed wavelength of 212nm by using an ultraviolet spectrophotometer to obtain the mass of shea butter W1 in the extract, wherein the initial oiling rate R1 of shea butter is W1/W2 × 100%, and the test results are shown in Table 3.
The wearable and washable shea butter modified composite fabrics of examples 1 to 18 and comparative examples 1 to 2 were washed 30 times, 50 times and 100 times, respectively, and then the oiling rate R2 after N times of washing was measured according to the above method, and then the (%) loss rate was (1-R1-R2/R1) × 100% according to the formula, and the test results are shown in table 3.
TABLE 3 of examples 1 to 18 and comparative examples 1 to 2
By analyzing the examples 1 to 5 and the comparative examples 1 to 2 and combining the table 3, under the synergistic effect of the binding agent and the emulsifier, the loss rate of the shea butter is only about 15% after 30 times of washing, and half of the oiling rate can be still maintained after 100 times of washing, so that the fabric has long service life and good fastness to washing.
By analyzing examples 1 to 5, 6 and 7 and combining table 3, it can be seen that the leaching rate of the fabric after 30 times of washing is reduced to about 13% after the component ratio of the binding agent is adjusted.
As can be seen from analysis examples 8, 9 and 10 and table 3, the binding force between shea butter and fiber was reduced by further adjusting the component ratios of chitosan, monoglyceride and N-methylol acrylamide, and the loss rate after 30 washes was about 11%.
Analysis of examples 11, 12 and 13 in combination with table 3 shows that the emulsifier ratio is further optimized to make the shea butter more easily migrate in the finishing liquor and the fibers, and the wash loss of the fabric 30 is reduced to 10%.
It can be seen from the analysis of examples 14 and 15 and the combination of table 3 that the adjustment of the finishing time of the fabric and the pretreatment time of the fiber makes the internal structure of the fiber more uniform and consistent, and the bonding force with shea butter is better.
By analyzing the example 16, the example 17 and the example 18 and combining the table 3, it can be seen that the bonding force of the fiber after the dimethyl sulfoxide pretreatment and the shea butter is better, the washing loss rate of the fabric is reduced to 7% after 30 times of washing, and the washing fastness is better.
To sum up, the wear-resistant and wash-resistant shea butter modified composite fabric has the advantages of skin moistening and wear-resistant washing, and is suitable for being applied to high-grade underwear fabrics and female clothes.
