Description

Mixed spun yarn comprising antibacterial extract and manufacturing method thereof}

The present invention relates to a mixed spun yarn containing an antibacterial extract and a manufacturing method thereof.

Wool and polyester are examples of the most commonly used fibers for sportswear. Wool is a natural animal fiber made from sheep's wool, and has low thermal conductivity and high air content between fibers. Polyester fibers have excellent elasticity, hardly generate wrinkles, and have a cool touch.

Wool is more breathable than polyester. Although the weave of polyester can be adjusted to increase breathability, wool has excellent breathability if the same density and same weight are used. On the other hand, polyester has excellent durability and wool is relatively less durable. However, wool is widely used as a material for sports socks because the deodorizing effect of wool is superior to that of polyester. In terms of water absorption, wool has a whopping 5 times water absorption capacity compared to polyester. Wool can absorb up to 35% of its weight in moisture.

As such, wool and polyester have distinct advantages and disadvantages, and there is a limit in that their use is limited depending on the purpose. In order to solve the above problems, clothes have been produced by blending wool and polyester fibers, but clothes manufactured by simple blending with conventional polyester fibers do not effectively alleviate the shrinkage property, and only the hygroscopicity is still It absorbs sweat because it is strong, but it does not release it, so there was a disadvantage that it could not maintain comfort.

Korean Patent Registration No. 10-2262770 has produced a blended yarn using wool and polyester, but there is no mention of water repellency and other performance, so there is a limit to overcoming the limitations of the conventional blended yarn.

Accordingly, the inventors of the present invention completed the invention by developing a blended spun yarn with excellent functionality for use in sportswear, underwear and other clothing by imparting water repellent and other performance and processing natural extracts.

Hereinafter, the present invention will be described in detail below.

Step (1) is a step of preparing a wool saw and polyester fibers. This step is a step of preparing a fiber material for producing a blended spun yarn. The step of preparing the wool saw and the polyester fiber may be to prepare the wool saw and the polyester fiber having an average diameter of 1 to 4 denier made of wool yarn having an average diameter of 20 to 22 μm.

At this time, if the diameter of the wool yarn constituting the wool top is less than 20 μm, the strength of the wool yarn constituting the wool top may be reduced, and if it exceeds 22 μm, the shrinkage of the wool top is strong, so that the mixture prepared according to the embodiment of the present invention The washing stability of the spun yarn may decrease.

The polyester fiber may be a polyethylene terephthalate (Poly Ethylene Terephthalate, PET) fiber.

If the thickness of the polyester fiber is less than 1 denier, the strength of the polyester fiber may be reduced, and if it exceeds 4 denier, the thickness of the polyester fiber is thicker than that of wool, making it difficult to spin uniformly with wool. There may be difficulties in the manufacture of blended yarns.

Preferably, the polyester fiber in the fiber preparation step may be a COOLMAX (E.I. DuPont) fiber having a thickness of 1 to 4 denier.

Preferably, the fiber preparation step may be to prepare a wool saw having a yarn diameter of 21 μm and a Coolmax fiber having a thickness of 2 denier.

If the Coolmax fiber is prepared as polyester fiber in the fiber preparation step, the mixed spun yarn manufactured according to the embodiment of the present invention can absorb and release sweat more smoothly together with the wool, so that the mixed spun yarn manufactured according to the embodiment of the present invention It is possible to maximize the sweat perspiration and quick-drying properties of clothes made of spun yarn.

The step (2) is a step of soaking for 24 hours by adding 10 to 20 parts by weight of purified water to the wool saw, and the step (3) is to heat the wool saw after the soaking process at 70 to 110 ° C. for 2 to 4 hours As a step, it is a step to prepare the wool top for easy post-processing. After step (3), a step of immersing the wool top in a nonionic surfactant may be further included to remove foreign substances from the wool. Non-limiting examples of the nonionic surfactant may be polysorbate 60, PEG-60, octyldodeceth-16, and ceteareth-6olivate.

Step (4) is a step of treating the pretreated wool top with an extract of one or more natural substances selected from the group consisting of rosemary, lavender, pine nut, chamomile, hibiscus, eucalyptus, peppermint, jasmine, propolis, and combinations thereof. This is a step in which the pre-treated and washed wool top is treated with natural extracts to impart antibacterial properties.
