preparation example Construction

[0023] The preparation method of traditional pure cotton woven white gray cloth comprises the steps:

[0024] Step 1, the original cloth preparation;

[0025] Step 2, carrying out singeing treatment to former cloth;

[0026] Step 3, desizing the white gray cloth after singeing;

[0027] Step 4, scouring the white gray cloth processed in step 3;

[0028] Step 5, the white gray cloth after step 4 is processed is bleached; Generally only adopt hydrogen peroxide (H 2 o 2 ) for bleaching. The principle of hydrogen peroxide bleaching: The main component of bleaching is hydrogen peroxide ion HO2-, hydrogen peroxide ion HO2- destroys the conjugated double bond of the pigment to achieve the purpose of decolorization and bleaching. Among them, bleaching with hydrogen peroxide needs to go through padding bleaching, steaming and washing in sequence, and the technological conditions for bleaching are: hydrogen peroxide H 2 o 2 The dosage is 2.5-3g / L; the dosage of sodium silicate wi...

Embodiment 1

[0034] Embodiment 1: a kind of preparation method of improved pure cotton woven white gray cloth, comprises the steps:

[0035] Step 1, prepare the original fabric, inspect the pure cotton woven white gray fabric in sequence, turn over the fabric and seam;

[0036] Step 2, singeing the white gray cloth after seaming, wherein the singeing adopts one front and one reverse singeing, the singeing effect reaches level 4, the vehicle speed is 100m / min, the burner is II, and the air pressure is 10mbar;

[0037] Step 3, carry out cold pad-batch desizing treatment to the white gray cloth after singeing; wherein the temperature of the feed liquid for cold pad-batch desizing is 70°C, the content of desizing enzyme is 8g / L, anion nonionic surfactant and oligomeric The content of body fat compound (scouring stabilizer ONE) is 10g / L;

[0038] Wrap the white gray cloth after cold pad-batch desizing treatment tightly with plastic film, take it out after rotating and stacking at room temperat...

Embodiment 2

[0049] Embodiment 2: to select gray cloth yarn count 40 * 40 for use, the plain weave poplin white gray cloth of density 130 * 80 is example, illustrate the pure cotton weaving white gray cloth preparation method of the present invention, comprise the steps:

[0050] Step 1. Raw fabric preparation: inspect, turn over and seam the woven white gray fabric;

[0051] Step 2. Singeing the white gray cloth after seaming, the singeing is required to be clean, and the singeing effect reaches level 5, wherein the singeing adopts one front and one reverse singeing, the speed is 130m / min, the burner is II, and the air pressure is 14mbar ;

[0052] Step 3, carry out cold pad-batch desizing and washing to the white gray cloth after singeing: desizing enzyme 8g / L, the compound (refining stabilizer ONE) consumption of anionic nonionic surfactant and oligomer fat is 10g / L L, the temperature of the material liquid is 70°C, roll it in the cold pad batch, wrap it tightly with plastic film after...

Abstract

The invention provides a modified preparation method of cotton woven grey cloth. Grey cloth prepared herein has very high whiteness; after the grey cloth is washed with water, the whiteness has very little decline; the whiteness of the grey cloth can last long. Cold pad-batch bleaching and washing are performed on the cotton woven grey cloth via a complex of sodium hydroxide, hydrogen peroxide solution, a negative non-ionic surfactant and an oligomer ester; bleaching is then performed via a complex of sodium hydroxide, hydrogen peroxide solution, a negative non-ionic surfactant and an oligomerester; the grey cloth is additionally brightened with stilbene bis-triazine brightener RSB. The grey cloth prepared via the modified preparation method herein has high whiteness, with the final whiteness reaching 155 and above, and has good washing fastness, the whiteness has a very low decline after 20 times of common domestic washing, and the decline value is less than 5.

Description

technical field [0001] The invention belongs to the technical field of fabric weaving and preparation, and in particular relates to an improved preparation method of pure cotton woven white gray cloth. The prepared white gray cloth is super white and washable. Background technique [0002] Pure cotton fiber is processed into primary color gray cloth after spinning and weaving, referred to as raw cloth or white gray cloth. Because white gray cloth contains a lot of impurities, it not only feels rough, yellow in color, but also has poor water absorption. If white gray cloth is to be processed into bright-coloured and colorful clothing fabrics, scouring and bleaching must be carried out to remove impurities, improve fabric whiteness and water absorption performance, etc., so as to meet the needs of subsequent processing. In daily life, white clothes or white home textile products are an indispensable color. In colorful and colorful clothing fabrics or home textile fabrics, whit...
