Description

Technical Field

[0001] This utility model belongs to the field of composite yarn technology, specifically relating to a paper composite yarn with unequal twist. Background Technology

[0002] Paper yarn is made from coniferous cellulose fibers that have been pulped into paper, then cut into narrow strips of 0.8-5mm width and twisted. Its preparation process is short, and there are no fly lint or cotton fibers in the textile processing. The fabrics made from it are lightweight, moisture-wicking, dry, breathable, antibacterial and deodorizing, do not generate static electricity, and do not pill.

[0003] However, due to the low strength and elongation of pure paper yarn, defects such as yarn breakage and holes occur when it is woven on a circular knitting machine, resulting in low yield, high production difficulty, and high manufacturing cost. Therefore, developing a paper composite yarn that not only has a high proportion of paper yarn in the composite yarn but also effectively improves the strength of the paper yarn and can be smoothly woven directly on a circular knitting machine has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the shortcomings of the existing technology, the present invention aims to provide a paper composite yarn with unequal twist, which has good moisture absorption, high strength, and large elongation, and can be smoothly woven on a circular knitting machine, making it suitable for the production of knitted T-shirts, polo shirts, and other knitted garments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention provides a paper composite yarn with unequal twist, characterized by comprising: paper yarn; and a first modified polyester supercool multifilament and a second modified polyester supercool multifilament sequentially wrapped around the outer surface of the paper yarn from the inside out. The twist direction of the first modified polyester supercool multifilament and its covering twist direction are opposite to the twist direction of the paper yarn, while the twist direction of the second modified polyester supercool multifilament and its covering twist direction are the same as the twist direction of the paper yarn. The twist of the paper yarn, the twist of the first modified polyester supercool multifilament, and the twist of the second modified polyester supercool multifilament decrease sequentially, and the covering twist of the first modified polyester supercool multifilament and the covering twist of the second modified polyester supercool multifilament also decrease sequentially.

[0007] The paper composite yarn with unequal twist provided by this utility model may also have the following characteristics: the twist direction of the paper yarn, the twist direction of the second modified polyester supercool multifilament itself and the covering twist direction are all Z twist direction, and the twist direction of the first modified polyester supercool multifilament itself and the covering twist direction are all S twist direction.

[0008] The paper composite yarn with unequal twist provided by this utility model may also have the following characteristics: the fineness of the paper yarn is 21-26S and the twist is 900-1000 twists / meter.

[0009] The paper composite yarn with unequal twist provided by this utility model may also have the following characteristics: wherein the first modified polyester supercool multifilament is a modified polyester supercool multifilament with a fineness of 50-75D, a single fiber number of 48-72F, a twist of 50-60 twists / meter, and a network of 90-100 network points / meter.

[0010] The paper composite yarn with unequal twist provided by this utility model may also have the following characteristics: wherein the covering twist of the first modified polyester supercool multifilament is 390-400 twists / meter.

[0011] The paper composite yarn with unequal twist provided by this utility model may also have the following characteristics: wherein the second modified polyester supercool multifilament is a modified polyester supercool multifilament with a fineness of 50-75D, a single fiber number of 48-72F, a twist of 30-40 twists / meter, and a network of 90-100 network points / meter.

[0012] The paper composite yarn with unequal twist provided by this utility model may also have the following characteristics: wherein the covering twist of the second modified polyester supercool multifilament is 290-300 twists / meter.

[0013] The paper composite yarn with unequal twist provided by this utility model may also have the following feature: the fineness of the paper composite yarn is 10-15S.

[0014] Compared with the prior art, the paper composite yarn with unequal twist of this invention has the following advantages:

[0015] (1) Paper composite yarn has high strength and good moisture absorption, and can be smoothly woven on a circular knitting machine.

[0016] Paper yarn has low strength and elongation. For example, paper yarn derived from 26S softwood cellulose fiber has a breaking strength of only 8.67 cN / tex and a breaking elongation of only 5.80% when twisted at 1000 twists / meter. In contrast, 75D / 72F modified polyester supercool multifilament has a breaking strength as high as 32.33 cN / tex and a breaking elongation as high as 23.78% when only weakly twisted. Therefore, in paper composite yarn, paper yarn is used as the core yarn, wrapped with high-strength and high-elongation fine modified polyester supercool multifilament in the reverse twist direction, and then re-twisted with fine modified polyester supercool multifilament in different twist directions. This effectively improves the strength and elongation of the paper composite yarn, which can be directly woven into fabric at high speed on a circular knitting machine. Meanwhile, the difference in twist gradient between the inner and outer sides allows the paper yarn to be fully exposed, preserving its style characteristics and moisture absorption properties. At the same time, the lower twist value on the outer side is beneficial to the moisture absorption of the paper composite yarn, thus improving the overall moisture absorption performance of the composite yarn.

[0017] (2) The paper composite yarn structure is stable.

[0018] The paper composite yarn consists of paper yarn, a middle layer of weakly twisted modified polyester supercool multifilament, and an outer layer of modified polyester supercool multifilament with different twist directions and weak twist. The twist value decreases from the inside to the outside, thus creating a twist difference. The paper composite yarn is not only structurally stable, but also better reveals the style characteristics and performance of the coarser paper yarn in the whole paper composite yarn, and has a soft touch.

[0019] (3) It is convenient to control the mass ratio of paper yarn in composite paper yarn.

[0020] By selecting paper yarns of different fineness and modified polyester supercool multifilaments of different fineness, the mass ratio of paper yarn in composite paper yarn can be directly controlled. In the paper composite yarn of this invention, the fineness of the composite paper yarn ranges from 10 to 15S, and the mass ratio of paper yarn to modified polyester supercool multifilament in the paper composite yarn is 71-75%: 29-25%, with a high proportion of paper yarn.
