[0051] The raw materials used in the yarn of the embodiment are all natural fibers, and the antibacterial effect is derived from antibacterial natural fibers;Moisture absorption and quick drying performance is derived from water repellent natural fibers and natural fibers;By drawing together natural fiber strip 21 and water repellent natural fiber strip 22 to form covering tape 23 to wrap antibacterial natural fiber core yarn 1, water repellent natural fibers are gathered on the outer periphery of the yarn, which can form good moisture absorption and quick drying effect under the condition of directional moisture absorption and guide, and can meet the functional requirement of water repellency under the premise of ensuring low proportion application.

The yarn of the utility model has simple structure and is easy to manufacture, reliable in performance and low in cost;It can meet the requirements of environmental protection, washing resistance and good wearing comfort.

[0052] It should be noted that: natural fiber strip 21 can be conventional or ordinary natural fiber strip. Conventional or ordinary natural fibers mainly include cotton, hemp, wool and silk. These fibers are directly obtained in nature and are an important material source for the textile industry.

[0053] In some embodiments, the mass percentage of each component of the yarn is: 25-35% of the antibacterial natural fiber core yarn 1, 20-50% of the water-repellent natural fiber strip 22, and 15-55% of the natural fiber strip 21; the thickness of the natural fiber strip 21 and the water-repellent natural fiber strip 22 is consistent, and the width of the water-repellent natural fiber strip 22 accounts for 1 / 4-1 / 3 of the total width of the covering strip 23.

[0054] The proportion of these fibers is mainly affected by functionality and cost, and the size of the basis weight; production practice shows that the minimum use ratio of the antibacterial natural fiber core yarn 1 for making the fabric have antibacterial properties can reach 25%, and the upper limit is limited by the maximum basis weight of the core yarn and the minimum basis weight of the wrapped strip; the minimum use ratio of the water-repellent natural fiber strip 22 for meeting the moisture absorption and quick drying performance can reach 20%, and the higher the ratio, the higher the cost, and the spinnability is not good; while ensuring the moisture absorption and quick drying effect of the yarn, the cost is reduced.
