Embodiment 1

[0025] Using 60 counts of pure cotton in the warp and weft direction, the density is 180*100, the finished product width is 58 inches, the weave is 1 / 1 plain weave, and the finishing method is ordinary finishing. The specific implementation steps are as follows:

[0026] (1) Singeing: Confirm the process according to the organizational specifications, select the position of the burner, burner 2, the flame intensity is 12mbar, and the vehicle speed is 90 m / min.

[0027] (2) Desizing: process parameters: steamer temperature 98°C, cloth stacking time 13 minutes, washing temperature 90°C, vehicle speed 80 m / min, desizing with enzymatic desizing.

[0028] (3) Mercerizing: According to the tissue specifications, determine the alkali concentration of 21 degrees Baume, the spray temperature of 65°C, the washing tank of 70°C, and adjust the pH value to 7.

[0029] (4) Whitening: add stabilizer 4g / L, hydrogen peroxide 15g / L, caustic soda 4g / L, whitening agent 5g / L according to tissue sp...

Embodiment 2

[0035] Using 70 counts of pure cotton in the warp and weft direction, the density is 200*100, the finished product width is 59 inches, the weave is 1 / 1 plain weave, and the finishing method is ordinary non-ironing. The specific implementation steps are as follows:

[0036] (1) Singeing: Confirm the process according to the organizational specifications, select the position of the burner, burner 2, the flame intensity is 12mbar, and the vehicle speed is 90 m / min.

Abstract

The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a preparation method for pure cotton white fabric with long-lasting whiteness. The preparation method of the pure cotton white fabric with long-lasting whiteness according to the present invention comprises the following steps: singeing → desizing → mercerizing → whitening → post-finishing treatment; the fabric is a variety of warp and weft all-white yarn, and the finished product width is 53-61 inch. The whiteness value of the finished product prepared by adopting the preparation method of the pure cotton white fabric with lasting whiteness described in the present invention is high, and the whiteness value of the finished fabric after processing reaches more than 150, and is washed according to the AATCC 135 standard washing method, and washed 50 times The whiteness is reduced within 2%; the soaping fastness reaches above 4‑5, and the strength of the fabric does not decrease before and after whitening. This method is simple in process and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a preparation method for pure cotton white fabric with long-lasting whiteness. Background technique [0002] Cotton fiber is one of the most widely used textile raw materials due to its excellent performance such as moisture absorption, breathability, soft feel, and comfortable wearing. For yarn-dyed white fabrics, the whiteness is affected during the weaving, sizing and finishing processes, resulting in low whiteness of white fabrics; and the whiteness will still decrease after washing during wearing. [0003] At present, there is a great demand for white fabrics in the market, especially white fabrics with high whiteness and washability. Although there are some white fabrics on the market that can meet high whiteness, their washing fastness is not enough. Therefore, we need to study the process of fabric finishing and processing to achieve the g...
