Embodiment 1
[0077] A graded standard sample of color fastness to rubbing of cotton cloth, the color fastness to dry rubbing of the standard sample is grade 2 to grade 5, and the color fastness to wet rubbing is grade 1 to grade 3. The specific preparation method is as follows:
[0078] 1) Gray cloth: Choose pure cotton woven plain gray cloth with relatively flat surface and less surface defects. The parameters of the gray cloth are: warp density 84 threads / inch, weft density 60 threads / inch, warp and weft yarn count 32Ne, square meter weight 112g / ㎡, width 90cm.
[0079] 2) Pretreatment: raw fabric preparation, singeing, desizing, scouring, bleaching;
[0080] Singeing→fire extinguishing→cloth falling, the singeing series reaches 3~4 grades.
[0081] Pre-treatment process of annealing, boiling and bleaching: the one-bath pre-treatment process of alkali oxygen is adopted, and the whiteness is required to reach more than 80%. Process flow: padding working liquid → steaming (90-95°C / 80min)...
Embodiment 2
[0121] A graded standard sample of color fastness to rubbing of cotton cloth, the color fastness to dry rubbing of the standard sample is grade 2 to grade 5, and the color fastness to wet rubbing is grade 1 to grade 3. The specific preparation method is as follows:
[0122] 1) Gray cloth: Choose pure cotton woven plain gray cloth with relatively flat surface and less surface defects. The parameters of the gray cloth are: warp density 90 threads / inch, weft density 56 threads / inch, warp and weft yarn count 40Ne, square meter weight 104g / ㎡, width 90cm.
[0123] 2) Pretreatment: raw fabric preparation, singeing, desizing, scouring, bleaching;
[0124] Singeing: Gas singeing machine is adopted, and the technological process is: cloth feeding → brushing → singeing → fire extinguishing → cloth falling, and the singeing series reaches 3-4 levels.
[0125] Pre-treatment process of annealing, boiling and bleaching: the one-bath pre-treatment process of alkali oxygen is adopted, and th...
Embodiment 3
[0164] A graded standard sample of color fastness to rubbing of cotton cloth, the color fastness to dry rubbing of the standard sample is grade 2 to grade 5, and the color fastness to wet rubbing is grade 1 to grade 3. The specific preparation method is as follows:
[0165] 1) Gray cloth: Choose pure cotton woven plain gray cloth with relatively flat surface and less surface defects. The parameters of the gray cloth are: warp density 80 threads / inch, weft density 62 threads / inch, warp and weft yarn count 32Ne, square meter weight 100g / ㎡, width 90cm.
[0166] 2) Pretreatment: raw fabric preparation, singeing, desizing, scouring, bleaching;
[0167] Singeing: Gas singeing machine is adopted, and the technological process is: cloth feeding → brushing → singeing → fire extinguishing → cloth falling, and the singeing series reaches 3-4 levels.
[0168] Pre-treatment process of annealing, boiling and bleaching: the one-bath pre-treatment process of alkali oxygen is adopted, and th...
