[0039] Embodiment 1:

[0040] A method for preparing a lightweight wear-resistant composite base fabric provided in this embodiment includes the following steps:

[0041] S1: Yarn selection, warp yarn chooses 10D / 5F semi-bright DTY nylon 66 yarn, weft yarn chooses 10D / 5F semi-bright DTY nylon 66 yarn.

[0042] S2: Slitting warping, at a speed of 200m / min, the warp yarn selected in step S1 is warped into a whole beam through a slitting warping machine.

[0043] S3: Sizing: using HW-126 sizing agent to size the entire shaft of step S2 at a speed of 150 m / min through a sizing machine to form a sizing shaft to prevent the warp yarn from fuzzing and breaking.

[0044] S4: combining the pulp beams in step S3 into one weaving beam at a speed of 40 m / min through a combining machine.

[0045] S5: Weaving, using 408 double-jet machine, at a speed of 230rpm, the warp yarn is sent out by the head, and the up and down opening movement of the heald frame is coordinated with the reed reciprocating beating movement to cross-weave the head warp yarn and the weft yarn into a checkered grey cloth with a warp density of 110 strands / inch and a weft density of 92 strands / inch. The checkered grey cloth has a single checkered edge and the checkered side length is 5mm. Figure 7 shown.

[0046] S6: Desizing and washing: the lattice fabric woven in step S5 is processed by a tension-free desizing machine at a speed of 10 m / min and a temperature of 80°C for 10 minutes to clean the sizing agent and impurities on the fiber surface. The desizing aid includes: 8 g / L NaOH, 2 g / L degreasing agent, and 3 g / L scouring agent.

[0047] S7: dyeing, using acid dye to perform overflow dyeing on the checkered fabric after desizing and washing in step S6. Figure 8 As shown, the dyeing process includes: adding acid leveling agent at room temperature for 5 minutes, adding acid dye acid control for 40 minutes, controlling the pH to 3-6, heating to 60°C and holding the temperature for 10 minutes, heating to 120°C at a heating rate of 1°C / min and holding the temperature for 40 minutes, dyeing, cooling to 80°C at a cooling rate of 1°C / min, holding the temperature for 20 minutes, draining and washing after fixing, and discharging the cloth after washing.

[0048] S8: In the middle setting, the track setting machine heat sets the checkered grey cloth after dyeing in step S7 in an oven at a speed of 60m / min and a temperature of 160°C for 2min. At the same time, the weft bend is adjusted through the cloth mesh corrector to make the warp and weft yarns perpendicular to each other.

[0049] S9: Splashing and shaping, using liquid preparation equipment to prepare treatment agents and pouring them into the rolling tank. The treatment agents include 30g / L of Dajin fluorine water-splashing agent, 5g / L of isocyanate bridging agent, 2g / L of amino silicone softener, and 40g / L of isopropyl alcohol penetrant. Using a track-type shaping machine, the checkered fabric after heat setting in step S8 is rolled through the rolling tank and roller at a speed of 10m / min. After rolling, it enters the pre-oven with a liquid rate of 60% and pre-baked at 150℃ for 2min, followed by baking at 160℃ for 2min, and cooling to obtain a lightweight wear-resistant composite base fabric. Physical property test: The abrasion resistance tested by ISO 12947-2:1998 (2000) (9KPA) can reach 30,000 times. The tear strength tested by ISO 13937-2:2000 can reach 8N in warp direction / 7N in weft direction. The tensile strength tested by ISO 13934.1-2013 can reach 175N in warp direction / 134N in weft direction. It feels dry.

[0050] The present invention selects nylon 66 yarn and matches it with a checkered lattice structure to reinforce tearing, so that the fabric can be both lightweight and wear-resistant. Nylon 66 yarn has high strength, can reach 5g / d, and has good wear resistance. By designing a complete set of process combinations including yarn selection, fabric structure, dyeing and finishing, the disadvantage of insufficient wear resistance of the lightweight composite base fabric is improved, while retaining a dry touch to the maximum extent; the lightweight wear-resistant composite base fabric (5mm three-checkered edges) processed by this process can achieve a wear resistance test of more than 40,000 times according to the Martindale method GB / T21196.2-2007 (9KPA).

[0051] like Figures 1 to 6As shown, the liquid preparation equipment includes a liquid preparation frame 1, a stirring assembly 2, an air supply assembly 3, a mounting frame 4, and a ring body 5. The top of the liquid preparation frame 1 is fixed with a ring body 5, the top of the ring body 5 is fixed with a mounting frame 4, the stirring assembly 2 is fixed to the mounting frame 4, the stirring end of the stirring assembly 2 is located inside the liquid preparation frame 1, and an elliptical hole 6 is opened inside the ring body 5. The air supply assembly 3 is fixedly connected to the rotating end of the stirring assembly 2 and cooperates with the elliptical hole 6 to realize the air supply operation of the air supply assembly 3. The stirring end of the stirring assembly 2 has a plurality of air outlets 24, and the gas provided by the air supply assembly 3 is discharged through the air outlets 24. The upper left wall of the liquid preparation frame 1 is fixedly connected with a liquid inlet pipe, and the liquid inlet pipe is connected with the material-liquid ratio system. The lower right wall of the liquid preparation frame 1 is fixedly connected with a liquid outlet pipe. The mixing uniformity of the treatment agent affects the subsequent water-spraying shaping effect. The mixed liquid is stirred and mixed by the stirring component 2. At the same time, the stirring component 2 drives the air supply component 3 to rotate. The air supply component 3 cooperates with the elliptical hole 6 of the ring body 5 to realize automatic air supply of the air supply component 3, and the gas is injected into the rotating end of the stirring component 2, and finally discharged through the air outlet 24 at the stirring end of the stirring component 2. The mixed liquid is stirred and mixed in two different forms by the discharged gas, and the stirring efficiency is higher and the mixing is more uniform. In addition, the air supply does not require an additional power source. By cleverly cooperating with the elliptical hole 6, automatic air supply without electricity is realized, which is more energy-saving and environmentally friendly.

[0052] Among them, the air supply component 3 includes a cylinder body 31, an air outlet pipe 32, an air inlet pipe 33, a first one-way valve 34, a second one-way valve 35, a piston 36, a spring 37, a push rod 38, and a roller 39. The upper part of the rotating end of the stirring component 2 is fixedly connected with the air outlet pipe 32, the first one-way valve 34 is arranged on the air outlet pipe 32, the outer end of the air outlet pipe 32 is fixedly connected with the cylinder body 31, the inner side of the bottom of the cylinder body 31 is fixedly connected with the air inlet pipe 33, the second one-way valve 35 is arranged on the air inlet pipe 33, the inside of the cylinder body 31 is slidably connected with the piston 36, the upper and lower sides of the outer wall of the piston 36 are fixed with springs 37, the outer end of the spring 37 is fixedly connected to the outer wall of the cylinder body 31, the middle part of the outer wall of the piston 36 is fixed with a push rod 38, the outer end of the push rod 38 is arranged with a roller 39, the roller 39 cooperates with the elliptical hole 6, and the setting of the spring 37 ensures that the roller 39 is always in contact with the inner wall of the elliptical hole 6. When the stirring assembly 2 rotates, the outlet pipe 32 and the cylinder body 31 are driven to rotate, so that the push rod 38 and the roller 39 rotate. During the rotation process, they cooperate with the elliptical hole 6 to repeatedly push and pull the push rod 38, thereby repeatedly pushing and pulling the piston 36, sucking air from the air inlet pipe 33 into the cylinder body 31, and then blowing it to the rotating end of the stirring assembly 2 through the air outlet pipe 32, thereby realizing automatic blowing operation. The setting of the first one-way valve 34 allows air to flow from the cylinder body 31 to the stirring end of the stirring assembly 2 only through the outlet pipe 32, and the setting of the second one-way valve 35 allows air to flow from the outside to the cylinder body 31 only through the air inlet pipe 33. In this way, air is prevented from flowing back from the stirring end of the stirring assembly 2, and air is prevented from being discharged from the cylinder body 31 through the air inlet pipe 33.

[0053] A vertical rod 7 is fixed to the bottom of the push rod 38, and a plurality of stirring plates 8 are arranged at the lower part of the vertical rod 7. The vertical rod 7 is arranged on the push rod 38, and the stirring plates 8 are arranged so that the vertical rod 7 and the stirring plates 8 rotate with the push rod 38, further improving the uniformity of stirring and mixing; and while the push rod 38 rotates, it also performs an inward and outward translation action, driving the vertical rod 7 to rotate and translate inward and outward, so that the stirring plates 8 rotate and translate inward and outward, so that the stirring and mixing is more comprehensive and the stirring effect is better.

[0054] The stirring assembly 2 includes a motor 21, a hollow rotating shaft 22, and a first hollow stirring blade 23. The motor 21 is fixed to the mounting frame 4. The bottom end of the motor 21 is fixed with a hollow rotating shaft 22. The upper part of the hollow rotating shaft 22 is fixedly connected to the air outlet pipe 32. The lower part of the hollow rotating shaft 22 is fixedly connected with a plurality of first hollow stirring blades 23. The front and rear side walls of the first hollow stirring blades 23 are provided with a plurality of air outlet holes 24. The motor 21 rotates, driving the hollow rotating shaft 22 to rotate, so that the first hollow stirring blades 23 rotate to stir and mix the mixed liquid. The air sent in by the air supply assembly 3 enters the hollow rotating shaft 22, and enters the first hollow stirring blades 23, and is finally discharged from the air outlet holes 24.

[0055] The first hollow stirring blade 23 is staggered with the stirring plate 8. The staggered first hollow stirring blade 23 and the stirring plate 8 make the mixing more comprehensive and thorough.

[0056] The bottom end of the hollow rotating shaft 22 is fixedly connected with a second hollow stirring blade 25, which is located below the lowest stirring plate 8, and a plurality of exhaust holes 26 are provided at the bottom of the second hollow stirring blade 25. The second hollow stirring blade 25 is provided with a plurality of exhaust holes 26. The second hollow stirring blade 25 is provided with stirring at different positions to further improve the mixing effect, and the airflow blown out by the exhaust holes 26 arranged downward further promotes the liquid to flow, mix, and collide with the bottom wall of the liquid dispensing frame 1, which helps to mix different liquid components more quickly and improve the mixing uniformity.

[0057] The plurality of exhaust holes 26 include a first hole 261 and a second hole 262. The first hole 261 is vertically disposed at the center of the bottom of the second hollow stirring blade 25, and the second hole 262 is outwardly inclined disposed at the left and right sides of the bottom of the second hollow stirring blade 25. The orientation and position of the first hole 261 and the second hole 262 are disposed to better meet the mixing requirements, so that the liquid at the bottom and the liquid above it are circulated, exchanged and mixed.
