[0037] In this invention, the spinning process sequentially includes the opening and cleaning process, the carding process, the drawing process, the roving process, the spinning process, and the winding process.
[0038] In this invention, the preferred conditions for the cotton opening and cleaning process include: the mixing method preferably uses cotton bales for mixing; the preferred beater speed of the opening machine is 400-500 r / min. Since the lyocell fibers are soft and easily damaged, this invention preferably reduces damage to the lyocell fibers by lowering the beater speed of the opening machine.

[0039] In this invention, the preferred conditions for the carding process include: the distance between the carding machine cover and the cylinder is preferably 0.35–0.4 mm. This invention preferably avoids lyocell fiber entanglement by optimizing the distance between the carding machine cover and the cylinder. The licker-in speed is preferably ≤800 r / min. This invention reduces damage to the lyocell fibers by lowering the licker-in speed. In this invention, the carding cloth used in the carding process is preferably a low-density, shallow-tooth carding cloth, thereby reducing electrostatic adsorption.
[0040] In this invention, the preferred conditions for the drawing process include: 3 drawing passes, 6 pre-drawings for the first drawing, and 8 mixed drawings for the second and third drawing. This invention preferably improves the mixing uniformity of lyocell and cotton fibers by controlling the number of drawing passes. The preferred total draft ratio is 6 to 8 times; by controlling the draft ratio, this invention reduces unevenness in yarn count.
[0041] In this invention, the twist of the roving process is preferably 60-100 T / M. By controlling the twist of the roving process (60-100 T / M) to be 10-15% higher than that of the pure cotton roving process, this invention can prevent Lyocell fiber slippage. The relative humidity of the environment is preferably 60-65%, and the relative humidity meter measures the relative humidity of the workshop environment in the roving process.

The warp tightness is preferably 60-80%, more preferably 70-75%, the weft tightness is preferably 30-50%, more preferably 40-45%, and the total tightness is preferably ≥65%, more preferably 65-70%. This invention preferably optimizes the crispness of the lyocell fiber linen-like woven fabric by controlling the warp tightness, weft tightness, and total tightness.
[0046] In this invention, the weaving conditions preferably include: the weaving tension < 2.5N. This invention preferably controls the weaving tension to avoid excessive stretching that causes fuzz.
[0047] In this invention, the weaving preferably employs a plain weave or a twill weave structure.
[0048] In this invention, during the weaving process, a plain weave or twill weave structure is adopted. By adjusting the overall tightness, weft tightness, and warp tightness of the fabric, the fabric exhibits a texture and crispness similar to linen.
[0049] In this invention, the finishing process preferably includes sequentially performing a singeing process, a desizing process, a weft straightening process, and a shrinkage process.
[0050] In this invention, the preferred conditions for the singeing process include: flame temperature preferably 900-1000℃; wind speed preferably 15-40Hz; and vehicle speed preferably 60-100m / min.
[0051] In this invention, during the singeing process: the flame temperature is preferably 900-1000℃. Too low a temperature will result in incomplete singeing of the fuzz, while too high a temperature may damage the fibers or cause discoloration of the indigo dye (indigo is prone to sublimation at high temperatures, causing the fabric surface to turn reddish); the wind speed range is preferably 15-40Hz. Wind speed affects the stability and penetration of the flame: if the wind speed is too low, the flame will flicker and singeing will be uneven; if the wind speed is too high, the flame will be blown away, reducing thermal efficiency. The machine speed is preferably 60-100m / min. The machine speed and temperature must be matched: if the machine speed is too high, the fuzz removal rate will be insufficient (fuzz residue >10%), while if the speed is too low, it will easily lead to overheating and discoloration of the fabric surface; the purpose is to remove the fuzz from the fabric surface and bottom, making the fabric surface smooth and reducing pilling.
[0052] In this invention, the desizing materials used in the desizing process preferably include: biological desizing enzyme preferably 6-10 g / L, and nonionic penetrant preferably 3-5 g / L; the conditions of the desizing process preferably include: temperature preferably 50-60℃, and machine speed preferably 40-70 m / min.
[0053] In this invention, the desizing process is preferably carried out with the following materials: biological desizing enzyme at a concentration of 6-10 g / L, nonionic penetrant at a concentration of 3-5 g / L, temperature at a concentration of 50-60°C, and machine speed at a concentration of 40-70 m / min. The purpose is to remove the sizing agent (starch / PVA) added during weaving, restore the fiber's absorbency, and facilitate subsequent processing or hand feel requirements. This process can be increased or decreased according to actual needs.
[0054] In this invention, the weft straightening process is preferably electronic automatic weft straightening, with photoelectric sensors detecting the weft yarn angle → adjusting the roller tilt or segmented stretching in real time, and the weft skew is preferably ≤3%; the purpose is to correct the weft yarn skew (weft skew / weft bend) of the fabric, ensure the fabric surface is flat, and avoid garment twisting.
[0055] In this invention, the preferred shrinkage process includes: moisture regain setting (before entering the rubber blanket): preferably 12-18%; preferred steam temperature in the rubber blanket area: 100-110℃; preferred drying cylinder temperature: 120-140℃; preferred machine speed: 30-60m / min; preferred rubber blanket compression rate: 15-22%; preferred target warp shrinkage rate: preferably 1-3% for warp shrinkage rate and 1-3% for weft shrinkage rate, with the weft shrinkage rate being as small and stable as possible.
[0056] The present invention provides a lyocell fiber imitation linen woven fabric obtained by the manufacturing method described in the above technical solution.
[0057] In this invention, the lyocell fiber imitation linen woven fabric is preferably a denim woven fabric.
[0058] This invention provides the application of the lyocell fiber imitation linen woven fabric described above in clothing or home textiles.
[0059] In this invention, the clothing is preferably summer clothing, such as shirts, skirts, and casual jackets.
[0060] To further illustrate the present invention, the technical solutions provided by the present invention will be described in detail below with reference to the embodiments, but they should not be construed as limiting the scope of protection of the present invention.
[0061] Example 1
[0062] This embodiment provides a lyocell fiber linen-like woven fabric, the specific manufacturing process of which includes:
[0063] 1. Raw material preparation and quality proportion design:
[0064] Fiber selection: Custom-made 52mm long lyocell fibers were blended with 15-20mm long combed cotton fibers. The lyocell fiber imitation linen woven fabric prepared in this embodiment contains 85% lyocell fiber by mass.
[0065] In this embodiment, the yarn is spun into yarn. When the yarn is composed of lyocell fiber and cotton fiber, the mass content of lyocell fiber in the yarn composed of lyocell fiber and cotton fiber is 85%, and the mass content of cotton fiber is 15%.
[0066] Pretreatment: Lyocell fibers need to be pre-humidified (control the moisture regain to 12-14%) to reduce static electricity; cotton fibers need to be cleaned to remove impurities.
[0067] 2. Main spinning production processes
[0068] 2.1 Cotton opening and cleaning process
[0069] Mixing method: "Cotton bales mixed with cotton";
[0070] Key points of the process: Lyocell fibers are soft and easily damaged, so the opening beater speed needs to be reduced (e.g., reduced to 500 r / min);
[0071] Reduce the number of impact points to prevent fiber breakage and knot formation.
[0072] 2.2 Carding process
[0073] Spacer adjustment: Increase the cylinder-cover spacer (0.4mm) to avoid Lyocell fiber entanglement.
[0074] Speed control: Reduce the speed of the licker-in roller (800 r / min) to reduce fiber damage.
[0075] Needle cloth selection: Use low-density, shallow-tooth needle cloth to reduce electrostatic adsorption.
[0076] 2.3 Drawing process
[0077] Number of merging passes: 3 merging passes (first merging: 6 pre-merging; second and third merging: 8 mixed merging), to improve the uniformity of mixing.
[0078] Draft ratio: Total draft ratio is controlled at 8 times to reduce unevenness of yarn.
[0079] 2.4 Roving process
[0080] Twist coefficient: Increase the twist appropriately (15% higher than pure cotton) to prevent Lyocell fiber slippage.
[0081] Humidity control: Maintain relative humidity in the workshop at 60-65% to reduce fuzz.
[0082] 2.5 Spinning process
[0083] The ring spinning process is adopted, and the required yarn twist coefficient is 410.
[0084] Drawing process: The back zone draw ratio is reduced to 1.4 to 1.5 times;
[0085] The roller spacing is slightly larger than that of pure cotton (e.g., 25mm×45mm) to increase the yarn evenness and produce a hemp-like appearance.
[0086] Steel ring wire coil: A wear-resistant coated steel ring is selected to reduce fiber melting caused by frictional heat.
[0087] 2.6 Winding process
[0088] Tension control: Low tension (15cN) is used to avoid Lyocell fibers breaking due to poor tensile strength.
[0089] Yarn clearer setting: Off.
[0090] 3. Weaving process
[0091] The yarns are dyed and sized sequentially. During dyeing, the warp yarns are dyed with indigo dye, while the weft yarns are natural white. This embodiment does not have any special limitations on the sizing process.
[0092] Tightness design: Warp tightness is designed to be 75%, and weft tightness is designed to be 45%. Weaving tension setting: Low tension of 2.0N to avoid excessive stretching and pilling. Yarn selection: Warp yarn: 16S, weft yarn: 16S, single yarn. During the weaving process, a plain or twill weave structure is used. By adjusting the weft density and warp tension, the fabric exhibits a texture and crispness similar to linen.
[0093] 4. Finishing process
[0094] Post-finishing process: singeing process -- desizing process -- weft straightening process -- shrinkage process.
[0095] 1) Singeing process:
[0096] Flame temperature: 900℃. Too low a temperature will result in incomplete burning of fuzz, while too high a temperature may damage the fibers or cause discoloration of the indigo dye (indigo is prone to sublimation at high temperatures, causing the fabric surface to turn reddish); Wind speed range: 20~25Hz. Wind speed affects the stability and penetration of the flame: too low a wind speed will cause the flame to flicker and the fuzz to burn unevenly; too high a wind speed will cause the flame to be blown away, reducing thermal efficiency; Speed: 80m / min. Speed and temperature must be matched: too high a speed will result in insufficient fuzz burning rate (fuzz residue >10%), while too low a speed will easily cause the fabric surface to overheat and discolor; Purpose: To remove fuzz from the fabric surface and backing, making the fabric surface smooth and reducing pilling.
[0097] 2) Desizing process:
[0098] Desizing materials: 8g / L biological desizing enzyme, 5g / L nonionic penetrant; temperature: 60℃; machine speed: 60m / min; purpose: to remove the sizing agent (starch / PVA) added during weaving, restore the fiber's water absorption, and facilitate subsequent processing or hand feel requirements. This process can be increased or decreased according to actual needs.
[0099] 3) Weft straightening process: Electronic automatic weft straightening, photoelectric sensor detects weft yarn angle → real-time adjustment of roller tilt or segmented stretching, weft skew is controlled within ≤3%; Purpose: to correct weft yarn skew (weft skew / weft bend) in the fabric, ensure the fabric surface is flat and avoid garment distortion.
[0100] 4) Shrinking process (mainly pre-shrinking finishing):
[0101] Moisture regain setting (before entering the rubber blanket): 18%;
[0102] Steam temperature in the rubber blanket area: 110℃;
[0103] Drying cylinder temperature: 120℃;
[0104] Vehicle speed: 50m / min;
[0105] Rubber blanket compression rate: 20%;
[0106] Target meridional shrinkage rate: meridional shrinkage rate controlled at 1-3%, zonal shrinkage rate controlled at 1-3%.
