[0014] Compared with the prior art, the paper composite yarn of the utility model has the following advantages:
[0015] (1) The paper composite yarn has high strength and can be smoothly knitted on a circular machine.
[0016] The paper yarn has low strength and elongation, for example, the single yarn breaking strength of the paper yarn from 26S coniferous cellulose fiber is only 8.67 cN / tex and the elongation at break is only 5.80% when the twist is 1000 twists per meter; the single yarn breaking strength of the 60S modified polyester supercool yarn is 22.12 cN / tex and the elongation at break is 11.56% when the twist is 800 twists per meter; the single yarn breaking strength of the 75D / 72F modified polyester supercool filament is as high as 32.33 cN / tex and the elongation at break is as high as 23.78% when the twist is weak. Therefore, in the paper composite yarn, the paper yarns with the same twist direction are arranged in parallel with the fine modified polyester supercool yarns with high strength and elongation as the core yarn assembly, the proportion of the paper yarns is high, and the strength and elongation of the core yarn assembly are effectively improved; the modified polyester supercool filaments with higher strength and elongation and finer branches with the opposite twist direction are wrapped around the core yarn assembly at a lower twist, so that the paper composite yarn has high strength and elongation, the paper yarns in the core yarn assembly can be exposed, the style characteristics and performance of the paper yarns are retained, and the paper composite yarn can be directly woven into cloth at a high speed on a circular weft knitting machine.
[0017] (2) The paper composite yarn has stable structure.
[0018] Two paper yarns with the same twist direction are arranged in parallel and modified polyester supercool is used as the core yarn, and a fine modified polyester supercool filament is additionally wrapped around the core yarn assembly at a lower twist in the opposite direction, so that the core yarn assembly of the composite yarn is firmly bound and does not slip or become free, so that the paper composite yarn not only has stable structure, but also can better show the style characteristics and performance of the thicker paper yarn in the whole paper composite yarn.
[0019] (3) The paper composite yarn has the smooth and crisp style and performance characteristics of the paper yarn and the moisture absorption and soft style of the modified polyester supercool.
[0020] Paper yarn made of cellulose fibers of coniferous trees by papermaking, slitting and twisting, the cross section of which is hollow structure, and the paper fiber is light in specific gravity, so the yarn is light in quality and good in moisture absorption, and the textile made of pure paper yarn has the characteristics of hard and crisp touch, dry and breathable style, and has certain antibacterial and deodorant functions. The modified polyester supercool is grafted with hydrophilic groups on the polyethylene terephthalate polymer chain, adopts Y-shaped cross section and micro-groove aperture physical morphology structure, so that it has excellent moisture absorption, moisture conduction and quick drying performance, and when the fiber accounts for a certain mass ratio in the fabric, the moisture absorption, sweat absorption and quick drying functions can be achieved without the need of auxiliary finishing; the grafted hydrophilic groups have good antibacterial properties, and the excellent moisture absorption and quick drying properties of the fiber create a dry environment that is not easy for bacteria to breed, so that the supercool fabric has good antibacterial effect, and the fiber does not contain any silver and other heavy metals, and the moisture absorption, quick drying and antibacterial functions are durable. When the mass ratio of paper yarn and modified polyester supercool fiber in the paper composite yarn is 55-80%:45-20%, the touch style and performance characteristics of paper yarn and modified polyester supercool fiber can be fully exerted, and the comprehensive performance of the two different materials is combined, that is, the smooth and crisp style of paper yarn and the soft touch style of modified polyester supercool fiber are retained, and the moisture absorption, quick drying and antibacterial functions are integrated.
[0021] (4) The mass ratio of paper yarn in the composite paper yarn can be conveniently controlled.
[0022] By selecting paper yarns with different fineness, modified polyester supercool yarns and filaments with different fineness, the mass ratio of paper yarn in the composite paper yarn can be directly controlled. In the embodiment of the utility model, the mass ratio of paper yarn and modified polyester supercool fiber in the paper composite yarn is 55-80%:45-20%, and the proportion of paper yarn is high.
