Description

Technical Field

[0001] This invention belongs to the field of down jacket fabric technology, specifically relating to a volcanic rock antibacterial and thermal insulation fabric for down jackets and its preparation method. Background Technology

[0002] Down jackets consist of the fabric used to sew the garment shape and the down itself. They are generally worn in the cold winter. To maintain the good warmth of down jackets and to prevent the down fibers from breaking and causing down leakage, down jackets are washed less frequently. However, after prolonged wear, the down jacket fabric is prone to accumulating stains, sweat, and sebum secreted by sebaceous glands, which can easily lead to bacterial growth. Therefore, when choosing down jacket fabrics, warmth and antibacterial properties are important quality indicators.

[0003] Volcanic rock fiber is a functional fiber with added special substances from volcanic rock (volcanic stone). This substance can absorb light waves of various wavelengths and convert the absorbed light waves into heat and store it. The human body and the surrounding environment continuously release heat into the environment in the form of infrared rays. Volcanic rock (volcanic stone) can absorb this energy and convert it into heat energy, thereby raising the temperature of people wearing clothes and achieving the effect of keeping warm. Volcanic rock fiber also has certain antibacterial properties. Therefore, volcanic rock fiber can be used as a fiber material for textile down jacket fabrics.

[0004] However, in the dry winter, static electricity easily forms between down jackets, sweaters, and thermal underwear when putting on and taking off down jackets and when the body moves and rubs inside down jackets. This can easily lead to dry skin, and static electricity can also cause pain when putting on and taking off down jackets, resulting in low comfort. Therefore, a volcanic rock antibacterial and thermal fabric based on down jackets and its preparation method are provided. Summary of the Invention

[0005] The purpose of this invention is to provide a volcanic rock antibacterial and thermal insulation fabric for down jackets and its preparation method in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A volcanic rock antibacterial and thermal fabric for down jackets, wherein the volcanic rock antibacterial and thermal fabric is woven from modified volcanic rock fiber yarn, cotton fiber yarn, and soybean fiber yarn;

[0008] The modified volcanic rock fiber is obtained by adding velvet fiber, velvet seed oil, epoxy resin and nano silver to volcanic rock fiber in a certain proportion and then treating it with microwave irradiation.

[0009] As a further optimization of the present invention, the volcanic rock antibacterial and warm fabric, by weight, comprises 60-75 parts modified volcanic rock fiber yarn, 10-20 parts soybean fiber yarn, and 10-25 parts cotton fiber yarn.

[0010] As a further optimization of the present invention, the raw materials for preparing the modified volcanic rock fiber thread, by weight, include 45-54 parts of volcanic rock fiber thread, 20-30 parts of velvet fiber, 10-15 parts of velvet seed oil, 6-10 parts of epoxy resin, and 5-12 parts of nano silver.

[0011] A method for preparing volcanic rock antibacterial and thermal fabric for down jackets involves blending modified volcanic rock fiber yarn, cotton fiber yarn, and soybean fiber yarn to obtain yarn, then using this yarn as warp and weft yarn to obtain fabric, and finally hot-pressing and shaping it at 150-165℃ and allowing it to cool naturally to obtain the volcanic rock antibacterial and thermal fabric.

[0012] As a further optimization of the present invention, the preparation method of the modified volcanic rock fiber thread is specifically as follows:

[0013] Step 1: Clean the roots and stems of the jute to remove the soil, and then dry, soak, degumme, wash, bake, and crush them to obtain jute fiber. Mix the jute fiber with jute seed oil extracted from jute seeds and epoxy resin, and then ultrasonically disperse it into volcanic rock fiber thread.

[0014] Step 2: The volcanic rock fiber thread and nano-silver processed in Step 1 are placed into a processing device for microwave irradiation treatment to obtain modified volcanic rock fiber thread.

[0015] As a further optimization of the present invention, in step one, the roots and stems of Abutilon theophrasti are dried to a moisture content of 12% to 24%, the soaking temperature is 35℃ to 42℃, and the soaking time is 6 to 9 hours.

[0016] As a further optimization of the present invention, in step one, the vibration frequency of ultrasonic dispersion is 120-240 kHz.

[0017] As a further optimization of the present invention, in step two, the microwave irradiation treatment time is 6 to 10 minutes, the microwave irradiation treatment power is 500 to 600 W, and the microwave irradiation temperature is 100 to 125°C.

[0018] The beneficial effects of this invention are as follows:

[0019] 1) The volcanic rock antibacterial and thermal insulation fabric of the present invention has good antibacterial, antistatic and thermal insulation effects. The volcanic rock antibacterial and thermal insulation fabric is obtained by modifying the volcanic rock fiber yarn and blending the modified volcanic rock fiber yarn with cotton fiber yarn and soybean fiber yarn.

[0020] 2) In the modification process of the volcanic rock antibacterial and warm fabric of the present invention, the volcanic rock fiber threads can be activated by nano-silver under microwave irradiation treatment, and form a synergistic effect with velvet fiber and velvet seed oil, thereby improving the antibacterial performance and antistatic effect of the fabric.

[0021] 3) The present invention adds velvet fiber, velvet seed oil, epoxy resin and nano silver to volcanic rock fiber yarn and obtains modified volcanic rock fiber yarn after microwave irradiation treatment. The modified volcanic rock fiber yarn can still maintain or even exceed the heat preservation effect of the unmodified volcanic rock fiber yarn. That is, the addition of velvet fiber, velvet seed oil, epoxy resin and nano silver and microwave irradiation treatment will not reduce the original heat preservation effect of volcanic rock fiber yarn.

[0022] 4) The volcanic rock antibacterial and thermal fabric of the present invention can be used as the fabric of down jackets. It can be used as the lining of down jackets and come into contact with the sweaters and thermal underwear worn by the user. It is not easy to generate static electricity when putting on and taking off the clothes and when the body moves, making it more comfortable to use. Detailed Implementation

[0104] Experimental verification:

[0105] I. Antibacterial Test of Volcanic Rock Antibacterial and Thermal Fabric

[0106] Antibacterial tests were conducted on the volcanic rock antibacterial and thermal insulation fabrics produced according to Examples 1-3 and Comparative Examples 1-5 above. A blank group was also set up. The fabric of the blank group was woven from volcanic rock fiber yarn, cotton fiber yarn, and soybean fiber yarn. The antibacterial test method was carried out according to the test method of GB / T20944.2-2007. The test data are shown in Table 1.

[0107] Table 1. Antibacterial Performance Test Data

[0108]

[0109] Note: All the above data have been validated for variance.

Therefore, it can be concluded that modified volcanic rock fiber yarn has a significant effect on improving the antibacterial properties of the fabric.

[0112] Based on the data from Example 2 and Comparative Examples 1-5, it can be seen that nano-silver can be activated under microwave irradiation treatment, and the activated nano-silver can form a synergistic effect with velvet fiber and velvet seed oil, thereby improving the antibacterial properties of the fabric.
