Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: polyester fabrics often have relatively large oil content during the weaving process, and polyester fabrics themselves are hydrophobic fabrics, so there are often more oil stains attached to polyester fabrics
Then, during the high-temperature and high-pressure dyeing process of polyester fabrics, the oil stains that come off from polyester fibers will easily lead to the aggregation of dye molecules, and the aggregated dyes will adhere to polyester fabrics, which will cause color stains and seriously affect product quality.
However, in the above-mentioned technical scheme, the oil stain adhering to the polyester is not treated in the whole printing and dyeing process, so the polyester fabric is prone to color stains during the dyeing process.

Embodiment 1
[0067] The invention discloses a printing and dyeing process of polyester fabric, which specifically comprises the following process steps:
[0068] S1: Preliminary pretreatment of gray cloth, specifically including the following process steps:
[0069] a. Pre-shrinking, specifically putting the gray cloth into a sodiumhydroxide solution with a mass concentration of 4%, and treating it at a temperature of 130° C. for 40 minutes to obtain a gray cloth 1; then cleaning the gray cloth 1 to the pH value of the cleaning water It is equal to 8, that is, gray cloth 2 is obtained;
[0070] b. Presetting, specifically presetting the second gray cloth obtained in step a at a temperature of 180° C. to obtain a pretreated gray cloth.
[0071] S2: Secondary pretreatment of the gray cloth, that is, using a cleaning agent to wash the pretreated gray cloth obtained in step S1 with oil stains to obtain a cleaned gray cloth.
[0072] And the cleaning agent comprises the following components ...
Embodiment 2
[0105] The difference between embodiment 2 and embodiment 1 is that the gray cloth is not subjected to three pretreatments between step S3 and step S4, but the alkali weight reduction gray cloth is directly dyed.
[0106] The difference between embodiment 3-6 and embodiment 1 is that in step S1, each process parameter is calculated as the following table:
[0107]
[0108]
[0109] The difference between embodiment 7-9 and embodiment 1 is that the percentage by weight of each component in the cleaning agent is calculated as the following table:
[0110]
[0111] The difference between embodiments 10-13 and embodiment 1 is that in the preparation process of surfactant, each process parameter is calculated as the following table:
[0112]
[0113]
[0114] The difference between embodiments 14-17 and embodiment 1 is that in the alkali reduction process of gray cloth, each process parameter is calculated as the following table:
[0115]
[0116]
[0117] The...
Embodiment 31
[0124] The difference between Example 31 and Example 1 is that no pretreatment is performed three times between step S3 and step S4, that is, the alkali weight-reducing fabric obtained in step S3 is not put into the treatment liquid for treatment, but the step S4.

Abstract
The invention relates to a printing and dyeing process for a terylene fabric, belonging to the technical field of fabric printing and dyeing processes. The process comprises the process steps of: S1.performing primary pretreatment on blank cloth to obtain pretreated blank cloth; S2. performing secondary pretreatment on the blank cloth, i.e., using a cleaning agent to wash oil stains on the pretreated blank cloth obtained in step S1 to obtain cleaned blank cloth; S3. reducing the use level of alkali of the blank cloth, i.e., performing alkali reduction on the cleaned blank cloth obtained in step S2 to obtain alkali-reduced blank cloth; S4. dyeing the blank cloth, i.e., dyeing the alkali-reduced blank cloth obtained in step S3 to obtain dyed blank cloth; and S5. performing aftertreatment. The process has the advantage of reducing the possibility of generating color spots on the terylene fabric.
Description
technical field [0001] The invention relates to the technical field of fabric dyeing and finishing technology, in particular to a printing and dyeing process of polyester fabric. Background technique [0002] Polyester is currently the most used variety of synthetic fibers in the world. In the process of polyesterprocessing, the dyeing process is quite different from other fibers. This is because there is no active group required for normal dyeing on the polyesterfiber. Therefore, the dyeing of polyester is often achieved through the swelling of the polyester fiber, and the disperse dye enters the polyester fiber to achieve the purpose of dyeing. [0003] For example, the Chinese invention patent application with the application publication number CN108978266A discloses a short process and method for printing and dyeing of all polyester fabrics. The all-polyester fabric is placed on the inspection table, mainly to check whether there are abnormalities such as drawing, wef...
