preparation Embodiment 1）

[0041] *Preparation of forsythia extract

[0042] Four P.P. nonwoven bags each containing 2 kg of pulverized powder of forsythia were put into a high pressure decocter, and 20 kg of water was added. After boiling at 130 °C for 3 hours, the decoction was pressurized in a hydraulic linkage to yield 15 kg of extract. Manufactured by concentrating it to 5kg through two rounds of filtration through a 5 micron filter.

[0043] This procedure was continued until 65 kg of concentrated extract was obtained.

preparation Embodiment 2～4）

[0045] *Preparation of honeysuckle, ginkgo leaf and cinnamon bark extracts

[0046] Concentrated extracts of honeysuckle, ginkgo leaves and cinnamon bark were prepared in a similar manner to Preparation Example 1, respectively.

preparation Embodiment 5～8）

[0048] Each of the extracts prepared in Preparation Examples 1 to 4 was mixed with a polypropylene substrate in an amount of 2 wt %, and then dried in a rotary hot air dryer at 60° C. for 2 hours to obtain a coated substrate.

[0049] Using a bench spinner, 2 kg of the coated substrate was spun in a typical fashion at 225°C to produce 150 denier / 28 filaments.

Abstract

The present invention relates to an antibacterial synthetic fiber manufactured by selecting one or more antibacterial plant extracts, mixing the plant extracts and a polymeric material for forming fibers, and melt-spinning the mixture at a temperature of 200 to 300 DEG C. The antibacterial synthetic fiber of the present invention may exhibit both very superior as well as continuous antibiotic action. In addition, the physical properties of the antibacterial synthetic fiber of the present invention are superior to those of conventional antibacterial synthetic fibers, and are thus very suitable for materials for general clothing.

Description

technical field [0001] The present invention relates to a method for producing antibacterial synthetic fibers. More specifically, the present invention relates to an antibacterial synthetic fiber comprising a plant extract and a method for manufacturing the same. Background technique [0002] Various attempts have been made to provide synthetic fibers with antimicrobial activity. Common among these is the incorporation of antimicrobial inorganic substances into synthetic fibers. Barleystone, jade, mica and silver nanoparticles are representative of such inorganic substances. However, the inorganic substances are used in trace amounts which are not sufficient to ensure the desired level of antimicrobial activity since they interfere with the fiber manufacturing process. In particular, silver nanoparticles, known for their good antibacterial activity, additionally have the disadvantage of negatively affecting the light fastness of fibers after the dyeing process, which is l...
