At present, the whitening process of cotton fabrics in the market generally adopts the whitening method of tentering. Some low-affinity whitening agents are selected, and the whitening of the fabrics processed in this way is completed by padding and drying in the same bath with the softener. low density, not bright color, poor washability, can not meet the requirements of high-grade fabrics

Embodiment 1
[0030] A high-whiteness pure cotton fabric processing technology, the fabric is CM80 / 2*CM80 / 2*160*72 tissue CP, including the following steps:
[0031] 1) Oxygen bleaching of the fabric after singeing, desizing and scouring;
[0032] 2) The bleaching agent used in the oxygen bleaching process is as follows: H 2 O 2 10g / L, organic peroxyacid U-2510g / L, NaOH 5g / L, chelating agent 6g / L, stabilizer 6g / L, the balance is water, the temperature of the steamer is 98℃, and the stacking time is 30min;
[0033] 3) mercerizing again;
[0034] 4) Then carry out the whitening process: choose a washing machine with a rolling groove and a steaming box, the rolling groove is a guide roll type rolling groove, the steaming box is a guide roll type steaming box with a cloth capacity of 60 meters, and the washing tank is a volume 10 washing tanks for 600L. The selected whitening solution is that the concentration of whitening agent PC is 10 g / L, the penetrating agent MRZ is 2 g / L, and the bala...

Abstract
The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a high-whiteness pure cotton fabric processing technology which comprises a whitening process. The whitening process comprises the following steps: conducting padding on a pure cotton fabric by use of a whitening liquid, carrying out steaming in a steaming box fully filled with saturated steam, and then carrying out water washing, neutralization and drying, wherein the pH value of the dried pure cotton fabric is controlled to be 6-7.5. According to the processing technology, padding by the whitening liquid, steaming, water washing, drying are conducted on the pure cotton fabric which is subjected to singeing, desizing, scouring, oxygen bleaching and mercerization, and then tentering and pre-shrinking are carried out; in the oxygen bleaching process, H2O2 is utilized for bleaching, and meanwhile organic peracid is added; a brightening agent with a medium or relatively high affinity is selected as the whitening liquid; after the pure cotton fabric is subjected to padding by the whitening liquid, the pure cotton fabric subjected to padding enters the guide roller type steaming box fully filled with the saturated steam for steaming, and then water washing, neutralization and drying are carried out; after the pure cotton fabric is treated according to the processing technology, the whiteness of the pure cotton fabric is improved to 155 or above, and the whitened pure cotton fabric is bright in color and has the soaping fastness of four-level or above.
Description
technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a process for processing high-whiteness pure cotton fabrics. Background technique [0002] All-cotton woven fabrics are natural cellulose fibers and are widely loved by consumers. All-cotton white fabrics are widely used in business suits. At present, the whitening process of cotton fabrics on the market generally adopts the method of tenter whitening. Some low-affinity whitening agents are selected, and padding and drying are completed in the same bath with softener on the tenter frame. Low degree, not bright color, poor washing effect, can not meet the requirements of high-end fabrics. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a high whiteness pure cotton fabric processing technology. After being processed by this technology, the whiteness of the pure cotton...
