Problems solved by technology

And the pilling is at level 2 or worse
In this way, even if the touch luster meets the customer's requirements, the physical and chemical indicators such as pilling and strength do not meet the customer's requirements.
Generally, the softener improves the hand feel, but the pilling and strength have a linear downward trend. On the contrary, the pilling and strength are done well, and the hand feel is not normal.

Embodiment 1

[0046] Embodiment 1. Optimization of the boiling and bleaching step

[0047] In this embodiment, a scouring and bleaching step is provided, and the scouring and bleaching step includes scouring and bleaching, wherein,

[0048] The working liquid formula of described scouring step is as follows:

[0049] Each 1 liter of scouring working solution contains:

[0050] NaOH 30~50g

[0051] Complexing agent Sirrix 2UD Liq 1~5g

[0052] Alkali-resistant scouring agent 2137 2~10g;

[0053] The finishing condition of the scouring step is 90-110°C, 20-60 minutes;

[0054] The working solution formula of described bleaching step is as follows:

[0055] Each 1 liter of bleach working solution contains:

[0056]

[0057] The finishing condition of the bleaching step is 90-110° C. for 20-60 minutes.

[0058] In order to study the influence of the above-mentioned parameters on the weft breaking strength of semi-finished products (after cooking and bleaching) and the weft breaking st...

Embodiment 2

[0080] Example 2. Optimization of the biopolishing step

[0081] In this embodiment, a biopolishing step is provided, and the working fluid formula of the biopolishing step is as follows:

[0082] Tencel decomposing enzyme Sincell 700 0.1~1%, owf%

[0083] Acetic acid 0.1~1%, owf%

[0084] The finishing condition of the biological polishing step is 6 times at 30-70°C.

[0085] The applicant has done test screening to a large amount of polishing enzyme art from several major aspects: a) the concentration of polishing enzyme b) the pH value of polishing process c) the temperature of polishing process, d) the time (that is, the number of passes) of polishing process f ) The weft fracture strength of the cloth determined by the polishing process g) The fluff of the cloth surface determined by the polishing process. The optimization process that finally determines the polishing step is as follows:

[0086] The working fluid formula of described biological polishing step is as f...

Embodiment 3

[0090] Example 3. Optimization of softening step

[0091] Soft step is provided in the present embodiment, and the formula of working liquid of described soft step is as follows:

Abstract

The invention provides a printing and dyeing technology of purified cotton home textile fabric. The printing and dyeing technology includes the first step of singeing enzyme desizing, the second step of scouring and bleaching, the third step of mercerized finishing, the fourth step of biopolishing, the fifth step of printing or dyeing, the sixth step of softening, the seventh step of primary calendaring, the eighth step of shrinking and the ninth step of secondary calendaring. According to the printing and dyeing technology, by means of optimization of the pretreatment process, addition of the biopolishing step, selecting and matching of softening addition agents and the soft gloss finishing of the physical property of the steps of calendaring, shrinking and calendaring, the purified cotton home textile fabric has silky gloss and the super soft hand feeling. Meanwhile, the zonal breaking strength and the anti-pilling performance of the purified cotton home textile fabric are ensured.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a printing and dyeing process for pure cotton home textile fabrics. Background technique [0002] 186×95 60s / 60s 100%C 105″ satin fabric is made of long-staple cotton, which has good strength. In recent years, new fibers such as tencel, modal, bamboo fiber, and milk fiber have attracted much attention, but in In the minds of consumers, pure cotton still has an irreplaceable absolute advantage. [0003] Due to the lack of domestic processing technology, there is still a big gap between high-quality pure cotton home textile fabrics and Europe and the United States in terms of gloss and feel. Especially for home textile fabrics with 250-300 threads, the fabrics produced by domestic printing and dyeing manufacturers cannot achieve the style of fabrics imported from Europe and the United States in terms of gloss and physical and chemical indicators. [0004] Taking the fab...
