Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a warping slashing process of a linen yarn according to an embodiment includes the steps of:
step S110: the linen yarns are humidified to ensure that the moisture regain of the linen yarns is 9-11%.
Wherein, the linen yarn in the step S110 is the yarn spun by the linen fiber.
Specifically, the steps of humidifying the linen yarns are as follows: the linen yarn is put into an environment with the temperature of 26-28 ℃ and the relative humidity of 65-75% RH for spray humidification, so that the moisture regain of the linen yarn is 9-11%. The flax yarn is humidified to reduce the warping breakage rate of the flax yarn, improve the production efficiency and improve the warping quality.
Step S120: the linen yarn is subjected to a warping process so that the linen yarn is wound on a beam.
Specifically, the apparatus used in step S120 is a warping machine.
Specifically, in the step of warping the linen yarns, the warping parts are 300 to 400 per beam so as to reduce the warping breakage rate of the linen yarns.
Furthermore, in the step of warping the linen yarns, the distance between two adjacent linen yarns is 0.4-0.5 cm, so that the adhesion condition of long hairiness between the adjacent yarns can be reduced, and the warping efficiency is improved.
Furthermore, in the step of warping the linen yarns, the warping reed adopts a mode of 1 reed empty and 1 reed. Through setting up warping row reed according to this mode for the yarn when appearing jumping the reed, it can jump to adjacent empty dent with it in, continues to carry out the warping and handles, thereby avoids the yarn to jump the reed to adjacent flax yarn corresponding dent in and the reed that leads to on have two yarns and slashing to form hank, the end of meeting, improves the warping quality.
In the present embodiment, in the step of warping the linen yarn, the linen yarn is warped using a warping machine, a creel of the warping machine is V-shaped, and the tension of the pre-tension lever is zero by closing the yarn gripper during the warping process. The pre-tension rod is used for providing certain tension for the yarn when the yarn feeder is opened so as to prevent the yarn from loosening. The V-shaped creel is not adopted for warping treatment of the linen yarns generally, the linen yarns are easy to loosen due to the fact that the linen yarns are heavy in weight in the production process due to the fact that the V-shaped creel is a tension-free creel, and the tension of the pre-tension rod is controlled by closing the yarn clamping device during warping treatment, so that warping treatment of the linen yarns by the warping machine directly adopting the V-shaped creel can be achieved, and the application range of the warping machine of the V-shaped creel is expanded.
Step S130: sizing the linen yarns.
Referring to fig. 2, the sizing process for the linen yarn comprises the following steps:
step S132: the linen yarn wound on the beam is pre-wet treated in water with the temperature of 65-75 ℃.
Specifically, the device used for sizing the linen yarn is a sizing machine. When sizing the linen yarn, a warp beam wound with the linen yarn is mounted on a sizing machine.
Specifically, the linen yarn wound on a beam is passed through a water tank filled with water at 65-75 ℃ to be subjected to pre-wetting treatment.
Step S134: the moisture regain of the linen yarn is controlled to be 35-45%.
Specifically, 30000N-50000N pressure is applied to the linen yarn so as to control the moisture regain of the linen yarn to be 35-45%. Wherein, the higher the pressure, the more water is pressed out, and the lower the moisture regain is.
Step S135: sizing treatment and wet leasing treatment are carried out on the linen yarns in sequence.
Before sizing treatment, the linen yarn is placed in hot water at the temperature for pre-wetting treatment in the step S132, the moisture regain of the linen yarn is controlled to be 35% -45% in the step S134, air in the yarn is extruded out through pressurization in the process, and water permeates into the linen yarn, so that the linen yarn capillary effect is promoted to be carried out in the subsequent sizing process, the contact area ratio of the serous fluid and the fiber is enlarged, the penetration depth of the serous fluid in the linen yarn is improved, the serous fluid is distributed in the linen yarn more uniformly, the sizing quality is better, and the weaving efficiency of the linen fiber is improved.
The sizing treatment is directly carried out on the sized linen yarns without drying, and the wet splitting treatment is beneficial to reducing the hairiness of the linen yarns.
Specifically, the sizing treatment comprises the following steps: the linen yarn is sized in the size and then pressure is applied to the linen yarn out of the size to press the size into the linen yarn and control the sizing amount. Wherein, the pressure applied by the pressure roller to the linen yarns in the pulp outlet groove is 15000N-25000N, and the sizing amount is controlled by controlling the pressure of the pressure roller.
Specifically, the slurry used in the sizing treatment step comprises the following components in percentage by mass: 40 to 45 percent of starch, 20 to 25 percent of polyacrylamide, 12 to 16 percent of polyvinyl alcohol, 12 to 16 percent of glycerol and 5 to 7 percent of emulsifying wax.
Wherein the starch is modified starch, such AS AS-1 modified starch from emollient assistant, Inc. of Changzhou city. The emulsifying WAX is WAX-1 emulsifying WAX from Changzhou lubricating aid Co.
Specifically, the wet leasing treatment is realized by adopting a wet leasing device.
Step S136: drying the linen yarns to ensure that the moisture regain of the linen yarns is 13-15%.
The moisture regain of the linen yarns is controlled to be 13% -15% through drying, so that the linen yarns have a proper moisture regain in the subsequent weaving process, and the weaving efficiency is improved. The wet strength of the linen yarn is usually higher than the dry strength, and within the moisture regain range, the linen yarn can be ensured to be always in an optimal state in the weaving process.
Specifically, the device used in the sizing treatment process of the linen yarns is a sizing machine, the speed of the sizing machine is 55-65 m/min in the sizing treatment process, and the drying temperature in the drying treatment is 100-105 ℃.
The speed of the whole sizing treatment process is controlled to be 55-65 m/min, so that 13-15% of moisture regain can be obtained at the drying temperature of 100-105 ℃ when the linen yarn passes through the drying zone (namely when the speed of the sizing treatment process is constant, a plurality of drying temperatures are too high, the moisture regain is low, and a plurality of drying temperatures are too low, the moisture regain is high).
Step S137: sequentially carrying out waxing treatment and coiling treatment on the linen yarns.
The surface of the linen yarn is coated with the wax film through waxing treatment, so that the surface friction coefficient of the linen yarn is reduced, and the weaving efficiency is improved.
Specifically, the device used in the waxing process is a double-sided waxing device. In the step of waxing, the waxing amount of the linen yarns is 0.4 kg/km to 0.6 kg/km. The surface friction coefficient of the linen yarns is smaller by controlling the waxing amount of the linen yarns. More specifically, in the step of waxing treatment, the temperature of wax liquid is 70-80 ℃; the rotating speed of the wax roller is 0.2 m/min to 0.4 m/min.
Further, in the step of sizing the linen yarns, the unwinding tension of the warp beam is 2.0 Bar-3.0 Bar; the tension of the linen yarn in the sizing treatment is 240N-300N; the tension of the linen yarn during drying treatment is 240N-300N; the tension of the linen yarn in the waxing process is 1760N-1980N; the winding tension during winding treatment is 2160N-2430N, the flax yarn is wound on the reel by using the reel and the yarn pressing shaft, and the pressure of the yarn pressing shaft during winding treatment is 1900N-2250N. The unwinding tension of the warp beam, the sizing tension of the linen yarn, the drying tension, the waxing tension, the winding tension and the pressure of the yarn pressing shaft are controlled according to the parameters, so that the linen yarn has a certain elongation after sizing treatment, the brittle fracture property of the linen yarn is improved, and the weaving efficiency is improved.

(1) in the warping slashing process of the linen yarns, the linen yarns are placed in hot water at the temperature for prewetting treatment before slashing treatment, and the moisture regain of the linen yarns is controlled to be 40%, so that the surface tension of the linen yarns can be reduced, the size absorption condition of the linen yarns can be improved, the penetration of size in the subsequent slashing treatment process is facilitated, the wear resistance of the linen yarns is improved, the hairiness on the linen yarns is better attached, and the hairiness amount is reduced; wet leasing treatment is adopted before drying treatment, so that the hairiness of the linen yarns can be further reduced; the linen yarns can have a proper moisture regain in the subsequent weaving process through the subsequent drying treatment; and the surface of the linen yarn is coated with the wax film by waxing treatment, so that the surface friction coefficient of the linen yarn is reduced, and the linen yarn obtained by the slashing process of the linen yarn can improve the weaving efficiency.
(2) The moisture regain of the linen yarns is controlled to be 9% -11% by humidifying the linen yarns before warping, warping ends are 300/shaft-400/shaft, the distance between two adjacent linen yarns is 0.4-0.5 cm, warping breakage rate can be effectively improved, warping breakage rate can be reduced to 3.2 times/million meters from 10.8 times/million meters before, and warping efficiency is improved.
(3) Because the linen yarns may jump to the reed corresponding to the adjacent linen yarns due to yarn jumping during the warping treatment process, two yarns are arranged on one reed, and when the warping arrangement reed adopts a mode of 1 reed empty 1 reed, the yarns can jump to the empty reed dent adjacent to the beaming arrangement reed and continue the warping treatment.
