Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.
[0036] Such as figure 1 As shown, the original technological process is as follows:
[0037] (1) Add penetrant into the tank with a concentration of 2g / L, heat up to 50°C, add the polyester-cotton knitted fabric into the tank and run for 5 minutes, so that the polyester-cotton knitted fabric is fully soaked in the aqueous solution;
[0038] (2) Add NaOH in the next 10 minutes, the concentration is 4g / L, and run for 5 minutes after adding NaOH, so that the fabric runs 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 Finally, run for 5 minutes to make the fabric run evenly in the solution;
[0040] (4) Rapidly heat up from 50°C to 95°C, keep warm at 95°C for 40 minutes, then cool down to 75°C and release water;
[0041] (5) Add water again and heat up to 50°C, ...

The invention belongs to the technical field of polyester-cotton knitted fabric treatment. Aiming at the problem that an existing fabric dyeing and finishing process cannot effectively improve the diffusion performance of a polyester-cotton fabric, the invention provides a method for improving the sweat-absorbing and quick-drying performance of the polyester-cotton knitted fabric. The method comprises the following steps of: adding a penetrant with the concentration of 2.0 + / -0.3 g / L into a cylinder, heating to 50 + / -3 DEG C, adding the polyester-cotton knitted fabric into the cylinder, and operating for 5 minutes; adding NaOH with the concentration of 10 + / -0.5 g / L, and operating for 5 minutes after the NaOH is added; adding H2O2 with the concentration of 10 g + / -0.5 / L, and operating for 5 minutes after the H2O2 is added; quickly heating to 110 + / -3 DEG C from 50 + / -3 DEG C, preserving the heat for 30 minutes at the temperature of 110 + / -3 DEG C, then reducing the temperature to 75 + / -3 DEG C, and draining water; and adding water again, heating to 50 + / -3 DEG C, and keeping the temperature at 50 + / -3 DEG C for 10 minutes. According to the method for improving the sweat-absorbing and quick-drying performance of the polyester-cotton knitted fabric provided by the invention, the diffusion performance of the fabric is fundamentally improved, and a more durable effect can be obtained from a microstructure of a fabric fiber.
Description
technical field [0001] The invention belongs to the technical field of polyester-cotton knitted fabric treatment, and in particular relates to a method for improving the sweat-absorbing and quick-drying performance of polyester-cotton knitted fabric. 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 properties such as light weight, moisture conduction, quick drying, coolness, comfort, easy cleaning, and no ironing. [0003] The methods to improve the sweat-absorbing and quick-drying performance of the fabric include: increasing the heat dissipation area of the fabric through the weaving process, such as weaving the fabric into a honeycomb mesh double-layer fabric. Grooves are formed on the surface of the fibers by means of fiber cross-section special-shaped (Y-shaped, cross-shaped, W-shaped, and bone-shaped, etc.), and the wicking and ...
