Embodiment Construction
[0035] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0036] like figure 1 As shown, the original process flow is as follows:
[0037] (1) Add a penetrant to the cylinder, the concentration is 2g / L, the temperature is raised to 50 °C, and the polyester-cotton knitted fabric is added to the cylinder to run for 5 minutes, so that the polyester-cotton knitted fabric is fully soaked in the aqueous solution;
[0038] (2) Add NaOH for the next 10 minutes, the concentration is 4g / L, and run for 5 minutes after adding NaOH to make the fabric run evenly in the solution;
[0039] (3) Add H for the next 10 minutes 2 O 2 , the concentration is 3g / L, after adding H 2 O 2 After running for 5 minutes, make the fabric run evenly in the solution;
[0040] (4) Rapidly heat up from 50°C to 95°C, keep at 95°C for 40 minutes, then cool down to 75°C and release water;
[0041] (5) Re-add water and raise the ...

The invention belongs to the technical field of polyester-cotton knitted fabric treatment. Aiming at the problem that the existing fabric dyeing and finishing process cannot effectively improve the diffusion performance of polyester-cotton fabrics, the present invention provides a method for improving the sweat-absorbing and quick-drying performance of polyester-cotton knitted fabrics, which includes the following steps: adding a penetrating agent into the cylinder with a concentration of 2.0±0.3g / L, heat up to 50±3°C, add polyester-cotton knitted fabric into the tank and run for 5 minutes; add NaOH, the concentration is 10±0.5g / L, run for 5 minutes after adding NaOH; add H 2 o 2 , the concentration is 10g±0.5 / L, add H 2 o 2 Then run for 5 minutes; quickly heat up from 50±3°C to 110±3°C, keep warm at 110±3°C for 30 minutes, then cool down to 75±3°C and release water; re-add water and heat up to 50±3°C, Incubate at 3°C for 10 minutes. The invention fundamentally improves the diffusion performance of the fabric, and can obtain a more durable effect starting from the microstructure of the fabric fiber.
Description
technical field [0001] The invention belongs to the technical field of processing polyester-cotton knitted fabrics, and particularly relates to a method for improving the sweat-absorbing and quick-drying properties of polyester-cotton knitted fabrics. Background technique [0002] Sweat-absorbing and quick-drying fabrics are widely used in sportswear, outdoor, travel and leisure wear, underwear and other fields because of their excellent characteristics such as light weight, moisture conduction, quick drying, coolness, comfort, easy cleaning and no ironing. [0003] The methods of improving the sweat-absorbing and quick-drying properties of fabrics include: increasing the heat dissipation area of the fabric through the weaving process, such as weaving the fabric into a honeycomb mesh-like double-layer fabric. The fiber cross-section is deformed (Y-shaped, cross-shaped, W-shaped and bone-shaped, etc.) to form grooves on the surface of the fibers. With the help of the wickin...
