The dyeing and finishing process comprises the following process steps: feeding into a dye vat (dyeing temperature is 120 ℃), drying (temperature is 110 ℃), washing with water, drying (temperature is 110 ℃) and adopting tannic acid to treat softening agent.
The dyeing process comprises the following dye components in parts by mass: 0.04 part by mass of disperse yellow, 0.0152 part by mass of disperse red, 0.022 part by mass of disperse blue and 0.5 part by mass of 98% glacial acetic acid. The temperature control of the dyeing process is as follows: the initial temperature is 30 ℃, the temperature is heated to 80 ℃ at 2 ℃/min, the temperature is kept for 5min, the temperature is further heated to 100 ℃ at 1.5 ℃/min, the temperature is kept for 6min, the temperature is further heated to 120 ℃ at 2 ℃/min, the temperature is kept for 40min, the temperature is further reduced to 110 ℃ at 1 ℃/min, the temperature is kept for 6min, the temperature is further reduced to 80 ℃ at 1.5 ℃/min, the temperature is kept for 20min, and the temperature is finally reduced to 33 ℃ at 2 ℃/min.
Waterproof after finishing: the waterproof requirement after dyeing and drying is as follows in the 4-stage process: the waterproofing agent is prepared according to 30g/L, the temperature of the oven is adjusted to be the first 100 ℃ for prebaking, the rest is 120 ℃ for baking, the speed of the vehicle is 48 yards, and the waterproofing agent is discharged out of the oven and cooled by cooling air and cold water cylinder, so that the temperature is reduced to 35 ℃ for stabilizing the form.
The fabric obtained was subjected to targeted performance detection, and the results are shown in table 6 below:
TABLE 6
When the bottom yarn is made of polyethylene, the cool feeling effect is slightly poor, and the surface flexibility of the surface yarn is stronger mainly because the surface yarn is subjected to soft treatment, so that the cool feeling fiber functionality is brought into play.
Example 7:
based on example 4, polyethylene fiber was modified: the process is realized by a double screw extrusion process, the processing temperature is 135-155 ℃, and the content of montmorillonite in the polyethylene fiber is 0.2 percent
The fabric obtained was subjected to targeted performance detection, and the results are shown in the following table:
TABLE 7
Example 8:
based on example 4, polyethylene fiber was modified: the process is realized by a double screw extrusion process, the processing temperature is 135-155 ℃, and the content of montmorillonite in the polyethylene fiber is 0.6 percent
The fabric obtained was subjected to targeted performance detection, and the results are shown in the following table:
TABLE 8
Example 9:
based on example 4, polyethylene fiber was modified: the process is realized by a double screw extrusion process, the processing temperature is 135-155 ℃, and the content of montmorillonite in the polyethylene fiber is 1.4 percent
The fabric obtained was subjected to targeted performance detection, and the results are shown in the following table:
TABLE 9
Example 10:
based on example 4, polyethylene fiber was modified: the process is realized by a double screw extrusion process, the processing temperature is 135-155 ℃, and the content of montmorillonite in the polyethylene fiber is 2.0 percent
The fabric obtained was subjected to targeted performance detection, and the results are shown in the following table:
table 10
The color fastness of the fabric is not increased by continuously increasing the content of montmorillonite, and at the moment, the mechanical properties of the fiber are deteriorated due to the fact that the content of montmorillonite is too high, and phenomena of yarn hairiness and yarn floating occur in the spinning process, so that the quality of the fiber is not improved.
The polyethylene fiber is not a common material in the field for preparing the fabric, the cool fabric is mainly realized by physically modifying the fiber, such as adding jade powder and other materials, and the application difficulty is that the polyethylene fiber is difficult to dye. The montmorillonite modified fiber dyeing technology is applied to polypropylene fibers more and is relatively less in the field of polyethylene fibers, and the dyeing modification of the polyethylene fibers and the application of the polyethylene fibers to the preparation of cool fabric are innovative.
The fiber modified by the montmorillonite has a hole effect, the heat conductivity of the fiber is increased under certain humidity, the rapid heat transfer is facilitated, and the heat absorption performance of the fiber is actually improved.
It should be noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted without departing from the spirit and scope of the technical solution of the present application, which is intended to be covered in the scope of the claims of the present application.
