[0002] As living standards improve, people have increasingly higher demands for the comfort of textiles. Natural fiber yarns often offer the best comfort, but they all suffer from poor strength. Silk, in particular, is expensive; while wool is not only expensive but also has poor dimensional stability. A common method is to blend various fibers to optimize the performance of pure fiber yarns, but fabrics made from blended yarns are often discarded after their lifespan, resulting in poor recyclability.

[0003] Therefore, it is necessary to improve the existing recyclable polyester filament blended yarns. Utility Model Content

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0023] The terms "outer surface" and "outer side" are used with reference to the normal use state of the recyclable polyester filament blended yarn, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] The recyclable polyester filament blended yarn disclosed in this utility model includes a reinforcing core layer 1, a moisture-absorbing inner layer 2, and a skin-friendly outer layer 3. The reinforcing core layer 1 includes at least one bundle of polyester filament 11 and at least one bundle of recycled carbon fiber filament 10. The moisture-absorbing inner layer 2 is wound around the outer surface of the reinforcing core layer 1, and the skin-friendly outer layer 3 is wound around the outer surface of the moisture-absorbing inner layer 2.

[0026] In some embodiments, the recycled carbon fiber filament 10 is untwisted and positioned at the center, while the polyester filament 11 is wound around the outside of the recycled carbon fiber filament 10.

[0027] In other embodiments, the polyester filament 11 is divided into a first polyester filament 101 and a second polyester filament 102. The first polyester filament 101 and the recycled carbon fiber filament 10 are untwisted and set as the central first reinforcing yarn, and the second polyester filament 102 is wound around the outside of the first reinforcing yarn.

[0028] Polyester filament 11 has high strength and abrasion resistance, which can improve the strength and durability of blended yarns; it can also reduce shrinkage and improve the dimensional stability of fabrics made from blended yarns; and it can also make the finished products easier to care for.

[0029] The raw material for recycled carbon fiber filament 10 is obtained from the recycled material of pyrolytic carbon fiber composite materials. Recycled carbon fiber filament has the characteristics of high strength and light weight; it is conductive, which improves the antistatic properties of fabrics made from blended yarns; and it also enhances the durability of fabrics made from blended yarns.

[0030] The reinforcing core layer obtained by combining polyester filament 11 and recycled carbon fiber filament 10 improves the utilization rate of resources. Combined with the structure of polyester filament and recycled carbon fiber filament winding, a reinforcing core layer with high strength, light weight, abrasion resistance, simple processing and low cost is obtained. After recycling, it can be used as the internal reinforcing layer of antistatic materials.

[0031] The moisture-absorbing inner layer 2 includes wool fiber yarn 21 and viscose fiber yarn 22.

[0032] In some embodiments, wool fiber yarn 21 and viscose fiber yarn 22 are spirally wound sequentially on the outer surface of the reinforcing core layer 1, with the spiral directions of wool fiber yarn 21 and viscose fiber yarn 22 being opposite.

[0033] In other embodiments, wool fiber yarn 21 and viscose fiber yarn 22 are twisted together in a spiral to form a composite yarn, which is then spirally wound around the outer surface of the reinforcing core layer 1.

[0034] The above-mentioned methods reduce the probability of fraying in the blended yarns of the reinforcing core layer 1 and the moisture-absorbing inner layer 2, resulting in higher strength and further cost reduction. Wool possesses excellent warmth retention, moisture absorption, and elasticity; high-quality wool yarn is exceptionally soft and comfortable, allowing the recycled blended yarn to be used as the internal filling layer of insulating materials. Viscose fiber yarn 22 offers good skin-friendliness, enhancing wearing comfort; it also improves fabric breathability; it absorbs and locks in moisture, helping to regulate body temperature and keep the body dry; its soft texture provides a delicate feel and comfortable wear; viscose fiber is low-cost, making its application more cost-effective; and its combination with wool fiber enhances abrasion resistance and elasticity, improving the durability of the blended yarn. To optimize the antibacterial effect of the yarn, an antibacterial layer 210 containing silver or copper ions is provided on the outer side of the wool fiber yarn 21.

[0035] The outermost layer (3) is made of silk (31). Silk fibers have a natural luster and a soft feel, making the garment very comfortable to wear. It has excellent breathability, regulates body temperature, keeping you cool in summer and warm in winter. Silk fibers can absorb and retain a certain amount of moisture, helping to maintain the skin's moisture balance. Silk is not prone to static electricity and does not easily attract dust, making it easy to clean and maintain. Combined with a reinforcing core layer and a moisture-wicking inner layer, it effectively overcomes the disadvantages of silk, such as high cost, poor abrasion resistance, and easy wrinkling.

[0036] Example 1

[0037] like Figure 1 As shown, the recyclable polyester filament blended yarn of Example 1 includes a reinforcing core layer 1, a moisture-absorbing inner layer 2, and a skin-friendly outer layer 3. The reinforcing core layer 1 includes at least one bundle of polyester filament 11 and at least one bundle of recycled carbon fiber filament 10. The moisture-absorbing inner layer 2 is wound around the outer surface of the reinforcing core layer 1, and the skin-friendly outer layer 3 is wound around the outer surface of the moisture-absorbing inner layer 2. The recycled carbon fiber filament 10 is untwisted and positioned at the center, and the polyester filament 11 is wound around the outside of the recycled carbon fiber filament 10.

[0038] The moisture-absorbing inner layer 2 includes wool fiber yarn 21 and viscose fiber yarn 22. The wool fiber yarn 21 and viscose fiber yarn 22 are spirally wound around the outer surface of the reinforcing core layer 1 in sequence, and the spiral directions of the wool fiber yarn 21 and viscose fiber yarn 22 are opposite.

[0039] The outer side of the wool fiber yarn 21 is provided with an antibacterial layer 210, which contains silver ions, and has not only good antibacterial properties, but also excellent antibacterial persistence.

[0040] Example 2

[0041] like Figure 2 As shown, Example 2 is based on Example 1, except that the polyester filament 11 is divided into a first polyester filament 101 and a second polyester filament 102. The first polyester filament 101 and the recycled carbon fiber filament 10 are untwisted and set as the central first reinforcing yarn, while the second polyester filament 102 is wound around the outside of the first reinforcing yarn. The composition of other layers remains unchanged.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
