Antibacterial yarn and its production process and acetate fabric

technical field

The invention relates to the field of textiles, in particular to an antibacterial yarn, a production process thereof and an acetate fabric.

Background technique

Acetate fabric is a fabric woven from acetate fiber, and acetate fiber is a man-made fiber made from acetate and cellulose through esterification reaction. It has good thermoplasticity, silk-like luster, and is not easy to generate static electricity. , but the tensile strength of acetate fiber is poor, and the fabric made of acetate fiber is more likely to be damaged.

Polyester fiber is made of polyterephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials, through esterification or transesterification and polycondensation. Polymer——polyethylene terephthalate (PET), a fiber made by spinning and post-processing, polyester fiber has the advantages of high strength, good thermal stability, wrinkle resistance, wear resistance, etc., but polyester fiber Static electricity is easily generated due to low water absorption.

Therefore, by blending acetate fiber and polyester fiber, the performance can be complemented, but both acetate fiber and polyester fiber lack antibacterial and antibacterial properties, and the fabric obtained after blending still has a large lack of antibacterial performance, which is difficult to satisfy consumers. demand, so there is still room for improvement.

Experiment 1

According to 20944.1-2007 "Evaluation of Antibacterial Performance of Textiles Part 1: Agar Plate Diffusion Method", the antibacterial effect of the acetic acid fabrics in each application example was tested, and the control page used 100% cotton fabrics.

After washing the acetic acid fabric once, test it, and record it as the antibacterial effect of washing once.

After washing the acetic acid fabric 100 times, test it, and record it as the antibacterial effect of washing 100 times.

When cleaning, put the acetic acid fabric with a length of 1m and a width of 1m into the washing machine, inject 1L of water into the washing machine, add 1ml of laundry detergent (Blue Moon Deep Cleansing Care Laundry Liquid), stir and wash in the washing machine for 30 minutes, rinse with clean water twice, and dry in the air , which completes 1 wash.

When cleaning 100 times, the interval between each cleaning is 30 minutes.

The specific detection data of Experiment 1 are shown in Table 1.

Table 1

According to the comparison of the data in Table 1, it can be concluded that the composite plant extract obtained by compounding water hyacinth, cassia bark, and houttuynia cordata has good compatibility with polyester blends, and can firmly adhere to the surface of spinning yarns to play a role. To achieve a long-lasting antibacterial effect, it can still maintain a good antibacterial effect after repeated washing, and when any one of water hyacinth, cinnamon, and houttuynia is replaced by other antibacterial medicinal materials, even if it is replaced The medicinal material with better antibacterial effect can only make the newly prepared fabric have good antibacterial effect, but after repeated washing, the antibacterial effect decreases significantly, and the antibacterial persistence is not good.

Through the combination of linear alkylbenzene sulfonate and nonylphenol polyoxyethylene ether, it can better improve the fastness of the active ingredients of the plant compound extract to the surface of the yarn, and it is more washable and antibacterial. It is maintained more permanently, and when any one of linear alkylbenzene sulfonate and nonylphenol polyoxyethylene ether is replaced by other surfactants, it can help improve the adhesion of the active ingredients of the plant compound extract to the The effect on the fastness of the yarn surface appears to decrease.
