Description

Technical Field

[0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a fabric printing process and a method for producing a fine wool fabric. Background Art

[0002] OPTIM fabric is a high-end outdoor fabric. The existing OPTIM fabrics are mostly plain or simple in color, and the styles are not rich enough. If you want to obtain fabrics with rich colors, stripe dyeing, printing and other processes are both feasible solutions.

[0003] Before printing, the fabric in the white grey cloth state needs to be scoured to remove impurities such as wool oil, slurry, wax stains, etc. on the white grey cloth. The scouring process causes the white grey cloth to shrink, making the fabric dense and tight with a waterproof effect. However, since the physical properties of fine wool such as moisture and heat are different from those of ordinary wool, the shrinkage of various parts of the fabric is inconsistent during the scouring process, resulting in different tightness between the peripheral area and the middle area, which in turn leads to different fuel permeability, resulting in unclear edges of the fabric after printing and dyeing, affecting the appearance quality of the product. Therefore, the use of printing technology on fine wool (OPTIM) fabrics is limited.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0005] In view of the above-mentioned defects, the present invention mainly provides a fabric printing process to solve the technical problem that the edge area of ​​the fabric is unclear after being printed and dyed by the printing process.

[0006] In order to solve the above problems, the present invention provides a fabric printing process, comprising the following steps: the fabric is subjected to singeing, continuous boiling, double boiling, dehydration, and primary drying in sequence; intermediate inspection, trimming, sizing, and secondary drying; digital printing, color fixation, and tertiary drying; shearing, moistening, calendering, and tank steaming; and the finished fabric is obtained after printing and dyeing;

[0007] The penetrant is added during the primary drying step.

[0008] According to the fabric printing process of the present invention, the penetrant is a non-ionic penetrant; the addition amount is 1 g / L.

[0009] According to the fabric printing process of the present invention, a softener is added in the three drying steps; the amount of the softener added is 5 g / L to 10 g / L.

[0010] According to the fabric printing process of the present invention, the first drying, second drying and third drying steps are all dried using a hot air dryer; the drying temperature is 120° C. and the vehicle speed is 10 m / min to 20 m / min.

[0011] According to the fabric printing process of the present invention, the color fixing step comprises:

[0012] Open-width washing is used to remove the sizing agent on the fabric after the digital printing step;

[0013] Dyeing vat process: the fabric is treated at 85±2℃ for 60 minutes to eliminate the internal stress in the fabric.

[0014] According to the fabric printing process of the present invention, the temperature of the open-width washing is 85±2° C. and the vehicle speed is 10 m / min to 20 m / min.

[0015] According to the fabric printing process of the present invention, the parameters of the multiple steps of the fabric printing process are set as follows:

[0016] In the singeing step, the flame intensity is 11.6 mbar to 12.6 mbar;

[0017] In the continuous cooking step, the temperature is 80°C to 90°C and the vehicle speed is 20m / min to 30m / min;

[0018] In the double boiling step, the temperature is 90°C and the boiling time is 30 to 40 minutes under normal pressure;

[0019] In the shearing step, the shearing blade distance is 0.35 mm and the vehicle speed is 18 m / min to 20 m / min;

[0020] In the calendering step, the temperature is 110°C, the speed is 20m / min to 26m / min, and the tension is 60%;

[0021] The tank steaming step has a processing pressure of 0.8 bar to 1.0 bar and a processing time of 240 seconds.

[0022] A method for producing a fine wool fabric, comprising a spinning process, a weaving process and the printing process; specifically:

[0023] The spinning process, used to spin finely drawn wool yarn into warp and weft yarns;

[0024] Weaving process, weaving warp and weft yarns into grey cloth;

[0025] The printing process is to print and dye the grey cloth to obtain the drawn wool fabric.

[0026] According to the method for making fine wool fabrics of the present invention, the warp yarns are produced by a weak steaming process, while the weft yarns are not steamed but left to stand naturally.

[0027] According to the method for making fine wool fabrics of the present invention, the weak yarn steaming process is: single cycle, steaming the yarn at 80° C. for 20 minutes.

[0028] In summary, the fabric printing process of the present invention allows the printing slurry to penetrate into the fabric surface by adding a penetrant during a drying process. Therefore, during the subsequent digital inkjet printing, the dye can penetrate into the fabric smoothly, and the dye can be evenly dispersed in various areas of the fabric. Therefore, the edge of the finished fabric after printing and dyeing has clear colors and the appearance quality of the product is good. The present invention also provides a method for producing a fine wool fabric, including a spinning process, a weaving process and the printing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Optionally, the permeabilizer of the present invention is a non-ionic permeabilizer; the added amount is preferably 1 g / L.

[0034] The fabric printing process of the present invention allows the printing slurry to penetrate into the fabric surface by adding a penetrant during a drying process. Thus, in the subsequent digital inkjet printing, the dye can penetrate into the fabric smoothly, and the dye can be evenly dispersed in various areas of the fabric. Figure 1 and Figure 2 Thereby, the pattern and color of the edge of the finished fabric after printing and dyeing are clear, and the appearance quality of the product is good.

[0035] Furthermore, in the three drying steps, a softener is added to make the fabric soft, smooth and soft. The amount of the softener added in the present invention is 5 g / L to 10 g / L. Those skilled in the art can select suitable known softeners, such as cationic softeners, nonionic softeners, anionic softeners and amphoteric quaternary ammonium salt softeners.

[0057] As an embodiment, the warp yarn of the present invention adopts a weak yarn steaming process, and the weft yarn is not steamed and is naturally left to stand; the compact spinning improves the yarn strength and makes the yarn have a temporary shaping effect, which facilitates the smooth progress of subsequent steps. At the same time, the yarn's rebound and shrinkage characteristics are retained, thereby ensuring the overall style of the fabric.

[0058] Optionally, the weak yarn steaming process is: single cycle, steaming the yarn at 80° C. for 20 minutes.

[0059] See also Figure 1 and Figure 2 The inventors set up multiple embodiments, using the above method to print and dye multiple colors and solid colors respectively. From the results, it can be seen that the patterns and colors at the edge of the fabric are clear and not deformed; the patterns in the center area and the edge area of ​​the fabric are consistent.

[0060] In summary, the present invention provides a fabric printing process, by adding a penetrant during a drying process, the printing slurry can penetrate into the fabric. Therefore, during the subsequent digital inkjet printing, the dye can smoothly penetrate into the fabric, and the dye can be evenly dispersed in various areas of the fabric.
