experimental example 1 dyes base cloth sanding preliminary treatment to the impact of colour fastness to rubbing
Select the red F2B of REACTIVE DYES, dye liquor concentration is that 10g/L carries out dyeing and soft Final finishing to sanding and the cotton plain of non-sanding, get six representative positions of stained clot-h and carry out resistance to dry, wet friction COLOR FASTNESS test, investigate sanding preliminary treatment and the difference without the pretreated stained clot-h colour fastness to rubbing of sanding respectively, manually grade under standard sources, the results are shown in Figure 1.
Known by Fig. 1, be starkly lower than without the pretreated result of sanding through the pretreated resistance to dry wet friction COLOR FASTNESS of sanding.The staining mechanism of textiles colour fastness to rubbing, mainly makes the dyestuff of the non-set of fabric face directly be transferred to standard calico causes under the effect of friction mechanism power.So fabric is after sanding process, the increase that fabric face amasss on the one hand causes the dyestuff being adsorbed on fabric face during dyeing to increase, and forms more loose colour; The villus fiber of fabric face is elongated on the other hand, and add the resistance of friction when rub resistance is tested, so more easily make the dyestuff on DYED FABRICS surface be transferred on standard calico, double action causes the decline of the colour fastness to rubbing of sanded cloth.So can consider to use sanded cloth for the standard fabric dyeing lower grade colour fastness to rubbing.
experimental example 2 dye strength is on the impact of stained clot-h colour fastness to rubbing
Select the red F2B of REACTIVE DYES, dyestuff dye liquor concentration is respectively 1g/L, 5g/L, 10g/L, 40g/L, 60g/L carry out dyeing and soft post processing to the cotton plain of sanding, and the center position getting stained clot-h carries out resistance to dry, wet friction COLOR FASTNESS test, investigate the impact of different dye liquor concentration on colour fastness to rubbing, the results are shown in Figure 2.
Known by Fig. 2, dye strength is larger on the impact of Fabrics Dyed with Reactive Dyes colour fastness to rubbing.The resistance to dry friction COLOR FASTNESS of dye strength of 1g/L is 5 grades, moisture-proof colorfastness to rubbing grade is 4 grades, along with the continuous increase of dye strength, when not changing other techniques of dyeing, the resistance to dry wet friction COLOR FASTNESS of fabric can constantly reduce, when dye strength reaches 60g/L, the resistance to unlubricated friction COLOR FASTNESS of fabric is 3 grades, and moisture-proof colorfastness to rubbing is only 1-2 level.This is because dye strength used is higher, the probability forming loose colour in fabric face accumulation is larger, has a strong impact on the moisture-proof colorfastness to rubbing of fabric.
By testing discovery above, can control by the concentration changing dyestuff the rub resistance standard items dyeing different brackets.
the soft Final finishing of experimental example 3 is on the impact of stained clot-h colour fastness to rubbing
Select the red F2B of REACTIVE DYES, dye liquor concentration is that 10g/L dyes to the cotton plain of sanding, dyeing later half cloth specimen does not do soft Final finishing, second half cloth specimen carries out soft Final finishing, two kinds of cloth specimens are got six representative positions respectively and does rub resistance experiment, investigate the difference without soft Final finishing and the stained clot-h colour fastness to rubbing through soft Final finishing, manually grade under standard sources, the results are shown in Figure 3.
Known by Fig. 3, uneven without each position of soft treatment fabric resistance to dry friction COLOR FASTNESS, between 2-3 level to 4 grade, after soft treatment, resistance to each position of dry friction COLOR FASTNESS of fabric is comparatively even, is 4 grades; Soft treatment is through for moisture-proof colorfastness to rubbing or each position without soft treatment is all more even.The uniformity obviously can improving textile dyeing through soft Final finishing is described, especially the uneven phenomenon of resistance to dry friction can be improved, this may be due in soft last handling process, the dye well dyeing assistant being adsorbed on fabric face once distributes under hygrometric state state again, makes dyeing become more even.
In addition, after soft treatment, resistance to dry, the wet friction COLOR FASTNESS of fabric all increases than the result without soft treatment.This is because one side energy removal part in soft treatment process sticks in the loose colour of fabric face, softener has certain lubrication on the other hand, the smoothness of fabric can be improved, fabric face coefficient of friction can be reduced when friction test, thus minimizing some dyes comes off, and makes colour fastness to rubbing to improve.
To sum up can obtain:
(1) be starkly lower than without the pretreated COLOR FASTNESS of sanding through the pretreated resistance to dry wet friction COLOR FASTNESS of sanding, so use sanded cloth as base cloth in the process of development COLOR FASTNESS standard fabric, its dyeing relatively easily controls, and more easily obtains the especially low-grade colour fastness to rubbing standard fabric of different brackets.
(2) along with dye strength increases, colour fastness to rubbing grade decreases.The rub resistance standard items of different brackets can be obtained by the concentration controlling dyestuff.
(3) the soft Final finishing of DYED FABRICS can improve the uniformity of REACTIVE DYES to cotton dyeing, and can improve the grade of resistance to dry wet friction COLOR FASTNESS to a certain extent.Uniformity and the stability of standard fabric can be improved by increasing soft Final finishing.
