step four: and the outer layer fabric, the interlayer fabric and the inner layer fabric are bonded together in a layering manner by using a bonding lining process to obtain the antibacterial and stain-resistant suit fabric.
Example 4:
the embodiment is a production process of an antibacterial and stain-resistant suit fabric, which comprises the following steps:
the method comprises the following steps: spinning and molding the wool fibers to prepare an outer-layer fabric, and mixing the outer-layer fabric according to a bath ratio of 1: 25, putting the fabric into an organic fluorine fabric finishing agent, treating the fabric in a two-dipping and two-rolling mode, pre-drying the fabric for 6min in an environment with the temperature of 90 ℃, and then baking the fabric for 5min in an environment with the temperature of 160 ℃ to obtain a stain-resistant outer fabric;
step two: spinning and molding polyester fiber to prepare an interlayer fabric;
step three: adding the antibacterial additive from example 2 into water to prepare an antibacterial solution with the mass concentration of 10%, soaking cotton fibers in the antibacterial solution for 5 hours, taking out the cotton fibers, placing the cotton fibers in a vacuum drying oven, drying the cotton fibers at the temperature of 60 ℃ to obtain antibacterial cotton fibers, and spinning and forming the antibacterial cotton fibers to prepare an inner-layer fabric;
step four: and the outer layer fabric, the interlayer fabric and the inner layer fabric are bonded together in a layering manner by using a bonding lining process to obtain the antibacterial and stain-resistant suit fabric.
Comparative example 1:
the difference between the comparative example 1 and the example 4 is that the inner layer fabric is manufactured by spinning and forming without soaking in an antibacterial solution.
Comparative example 2:
comparative example 2 is a light and thin antibacterial wool suit fabric provided in application No. CN 201811037889.5.
Comparative example 3:
the difference between the comparative example 3 and the comparative example 2 is that the light and thin antibacterial wool suit fabric of the comparative example 2 is placed in the antibacterial liquid in the example 4 to be soaked for 5 hours, and then taken out to be placed in a vacuum drying oven to be dried under the condition that the temperature is 60 ℃.
The antibacterial performance of the examples 3-4 and the comparative examples 1-3 is detected according to GB/T20944.3-2008 evaluation of antibacterial performance of textiles, wherein the sterilization method is high-pressure steam sterilization; the shaking solution is 0.03mol/L phosphate buffer solution; the contact temperature is 24 +/-1 ℃; the contact time is 18 h; the test strains are escherichia coli and staphylococcus aureus; the initial concentration of the strain is 2.5 multiplied by 104CFU/mL; the results are shown in the following table:
as can be seen from the data in the above table, compared with the examples, the antibacterial property of the western-style clothes fabric is greatly improved by using the antibacterial liquid in the comparative example 1, the antibacterial property of the fabric is improved by using the tencel and mint fiber blended yarn in the comparative example 2, but the effect is not obvious, and the antibacterial property is obviously improved by using the antibacterial liquid in the comparative example 3.
