Description

Technical Field

[0001] The present invention relates to the technical field of yarn spinning, and particularly relates to a processing device for improving the moisture absorption and moisture discharge performance of chemical fiber yarns. Background Art

[0002] Yarns are the raw materials for textiles. In terms of sources, yarns include yarns made of natural fibers such as cotton yarns and silk, as well as chemical fiber yarns including polyester filaments, nylon filaments, and polypropylene filaments. In the fields of clothing and home textiles, with people's increasing attention to health, clothing and home textile products made of natural fibers such as cotton yarns and silk are more favored by people because of their better moisture absorption and moisture discharge performance, and the moisture regain rate is close to that of human skin, compared with products made of chemical fiber raw materials with poor moisture absorption and moisture discharge performance. However, clothing and home textile products woven with chemical fiber yarns also have their own advantages such as relatively low prices and excellent ultraviolet resistance. Therefore, how to improve the moisture absorption and moisture discharge performance of chemical fiber yarns and produce inexpensive and high-quality textiles using chemical fiber yarns with improved moisture absorption and moisture discharge performance has always been a technical issue of great concern and interest in the textile industry. Up to now, the industry has mainly explored various methods to improve the moisture absorption and moisture discharge performance of chemical fiber yarns by imitating natural fibers. For example, chemical fiber filaments are processed into a hollow state with both ends of the chemical fiber filaments being penetrated. However, the periphery of the chemical fiber filaments processed in this way is still closed, so the improvement effect of the moisture absorption and moisture discharge performance is limited. Another example is to perform surface alkali weight reduction treatment on chemical fiber filaments to generate pits on the surface of the chemical fiber filaments to improve the moisture absorption and moisture discharge performance of the chemical fiber filaments. However, the chemical fiber filaments processed by this method still cannot achieve the moisture absorption and moisture discharge performance formed by natural fibers using the siphon principle, and the effect is also limited. Another example is that the method of strengthening the twist of chemical fiber filaments cannot increase much moisture absorption and moisture discharge amount because the density increases. Even there is, for example, a method for increasing the moisture absorption and moisture discharge function of chemical fiber filaments disclosed in the Chinese patent document with the application number 202010749908.8. By adding and twisting chemical fiber filaments and water-soluble filaments and then hydrolyzing them, this method can at most make the chemical fiber filaments fluffy to generate moisture absorption and moisture discharge, but it pollutes the environment and also increases a large cost. All in all, the current methods for improving chemical fiber filaments (chemical fiber yarns) generally have problems such as difficult implementation, high cost, limited improvement in the moisture absorption and moisture discharge performance of chemical fiber filaments, and easy environmental pollution.

[0022] The raw material yarn bobbin 1 is used to wind the chemical fiber yarns 100 to be processed.

[0023] The yarn unwinding tension loop 2 is used for tension compensation adjustment when the chemical fiber yarn 100 to be processed is radially unwound from the raw material yarn bobbin 1. The yarn unwinding tension loop 2 is a commercially available component.

[0024] The first turntable 3 is used for clockwise twisting of the chemical fiber yarn 100 unwound from the yarn unwinding tension loop 2; the first turntable 3 is a disk-shaped structural member that rotates clockwise during operation, and the first turntable 3 is provided with an eccentric hole for the chemical fiber yarn 100 to pass through; the chemical fiber yarn 100 unwound from the yarn unwinding tension loop 2 extends towards the first traction rubber roller 4 after passing through the yarn passing hole of the first turntable 3. The structures of the second turntable 5 and the third turntable 7 are the same as that of the first turntable 3.

[0025] The first traction rubber roller 4 is used for traction of the chemical fiber yarn 100 passing through the yarn passing hole of the first turntable 3 to make it move. The first traction rubber roller 4 is preferably a pair of rollers that rotate towards each other during operation.

[0026] The second turntable 5 is used for counterclockwise twisting of the chemical fiber yarn 100 passing through the first traction rubber roller 4; the second turntable 5 rotates counterclockwise during operation.

[0027] The second traction rubber roller 6 is used for traction of the chemical fiber yarn 100 passing through the eccentric hole of the second turntable 5 to make it move. The second traction rubber roller 6 is preferably a hybrid roller composed of a first roller rotating clockwise, a second roller rotating counterclockwise, and a third roller rotating clockwise.

[0028] The third turntable 7 is used for clockwise twisting of the chemical fiber yarn 100 output by the second traction rubber roller 6 again through its eccentric hole, and makes the chemical fiber yarn 100 after passing through the yarn passing hole of the third turntable 7 rotate spirally around the periphery of the heating rod 8. The third turntable 7 rotates clockwise during operation.

[0029] The heating rod 8 is arranged below the third turntable 7 and is used for generating and maintaining a temperature of 160 - 190 °C by energization to thermally set the chemical fiber yarn 100 spirally rotating around its periphery into a corrugated chemical fiber yarn 100. In this embodiment, the heating rod 8 is preferably made of a steel wire with a diameter of 3 mm.

[0030] The rubber pressure roller 9 is used to cooperate with the patterned roller 10 to apply pressure to the chemical fiber yarn 100 wound around the patterned roller 10; in this embodiment, the rubber pressure roller 9 is a textile rubber pressure roller with a smooth, elastic surface and a certain degree of hysteresis and weight.

[0031] The flower roller 10 is used to generate and maintain a temperature of 160 - 190 °C when electrified, heat iron the corrugated chemical fiber yarn 100 after passing through the rubber pressure roller 9, and under the pressure cooperation of the rubber pressure roller 9, randomly form spiral grooves 101-1 on the surface of the corrugated chemical fiber yarn 100. In this embodiment, the flower roller 10 is a roller with a number of turns of electric heating wires continuously wound obliquely on the surface of a cylinder. In this embodiment, the electric heating wires are preferably made of steel wires with a diameter of 0.5 mm.

[0032] The grooved drum 11 is used to wind the formed finished chemical fiber yarn 101 onto the finished yarn bobbin 12. The grooved drum 11 is a commercially available part commonly used in textile industry.

[0033] The finished yarn bobbin 12 is used to cooperate with the grooved drum 11 to collect the formed finished chemical fiber yarn 101.

[0034] The working principle, process and processing effect of the processing device for improving the moisture absorption and moisture discharge performance of chemical fiber yarns in this embodiment are briefly described as follows:

[0035] During operation, under the traction of the first rubber traction roller 4, the chemical fiber yarn 100 to be processed is unwound from the raw material yarn bobbin 1 and passes through the yarn unwinding tension loop 2 and the eccentric hole of the first turntable 3 rotating clockwise. The chemical fiber yarn 100 is twisted clockwise, and then the chemical fiber yarn 100 is pulled by the second rubber traction roller 6 and passes through the eccentric hole of the second eccentric wheel 5 rotating counterclockwise and is twisted counterclockwise again. After continuous clockwise and counterclockwise twisting, the chemical fiber yarn 100 becomes loose. The loose chemical fiber yarn 100 coming out of the second rubber traction roller 6 passes through the eccentric hole of the third turntable 7 rotating clockwise, and then under the drive of the rotation of the third turntable 7, the chemical fiber yarn 100 rotates spirally around the outer periphery of the electric heating rod 8. The high temperature generated and maintained by the energized electric heating rod 8 thermally shapes the chemical fiber yarn 100 rotating spirally around it into a corrugated chemical fiber yarn 100. The corrugated chemical fiber yarn 100 is wound around the flower roller 10 and under the pressing cooperation of the rubber pressure roller 9, is heat ironed by the electric heating wires of the flower roller 10, so as to randomly form spiral grooves 101-1 on the surface of the corrugated chemical fiber yarn 100. The processed finished chemical fiber yarn 101 is wound onto the finished yarn bobbin 12 by the grooved drum 11.

[0036] After being processed by this device, the chemical fiber yarn 100 becomes a finished chemical fiber yarn 101 in a fluffy corrugated shape with spiral grooves 101-1 on its surface. When the finished chemical fiber yarn 101 is used as warp and weft yarns to weave into cloth, the whole finished chemical fiber yarn 101 is fluffy and easy to absorb moisture. The spiral grooves 101-1 just pass through the front and back of the cloth surface. The tiny spiral grooves 101-1 are prone to generate a siphon effect to absorb and discharge moisture, thus significantly improving the moisture absorption and moisture discharge performance of the existing chemical fiber yarn 100.

[0037] The above embodiments are illustrative of the specific implementation manners of the present invention, rather than limitations thereof. Those skilled in the relevant technical field can still make various transformations and changes to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should fall within the scope of patent protection of the present invention.
