Embodiment one: single finishing agent arrangement
1,
Hydrophilic finishing agent FZ arrangement
Pending wool is put into the hydrophilic finiss liquid of the variable concentrations for preparing after wetting, by infusion process 1 arrangement.The sample drying that to put in order and be placed in the respective standard wetting balance device balance and measure moisture absorption weight after 24 hours then.
The hydrophilic finiss agent concentration is as follows: 2,3,4,6, and 10g/L
From above-mentioned data as can be known, the hygroscopicity of the wool sample of process hydrophilic finishing agent arrangement all has increase to a certain degree.Analysis on Mechanism mainly is that hydrophilic finishing agent changes fiber surface layer, improves the hydrophily of fiber, makes it to be easy to moisture absorption.
2, single sillicon oil treatment agent 818 arrangements
Pending wool sample put into silicone oil 818 dressing liquids that prepare and handle, then at 100 ℃ of oven dry 30min and be placed in the balancer of each standard humidity balance and measure moisture absorption weight after 24 hours down by infusion process 2.
Silicone oil 818 dressing liquid 8%owf
From above-mentioned data as can be known, after sillicon oil treatment agent arrangement, can improve the hygroscopicity of wool, because from the molecular structure of silicone oil 818, also contain hydrophilic radical, so increase through the wool hydroscopicity of silicone oil 818 arrangements.
The analysis of 818 pairs of wool hydroscopicity influences of hydrophilic finishing agent and silicone oil and finishing effect (feel):
Because more hydrophilic radical is arranged on the hydrophilic finishing agent structure, as-OH,-COOH etc., when finishing agent attached to wool fibre on the time, help the moisture absorption of wool fibre, but because the part finishing agent is deposited on the amorphous region or the fiber surface of fiber, make the wool surface become comparatively coarse, influenced the original smooth hand feeling of wool.And smooth through the wool fibre feel of silicone oil 818 soft finishing agents arrangement, softness, fluffy, drapability, elasticity are good, have gloss.This is because in the soft finish process, soft finishing agent is filled between the scale layer on wool surface, and the rough surface of fiber is repaired, and reduces the rubbing effect of wool fibre, has improved smooth degree.But the wool hydroscopicity rate of change through soft finish is little.Though because when arrangement, soft finishing agent is deposited on the wool scale layer, has covered the hydrophilic radical on wool surface, and the hygroscopicity of wool itself is descended to some extent, but silicone oil 818 is a kind of weak cation improvement silicone oil with reactive amino, has certain moisture.The effect that these two kinds of hydrophilies reduce and increase is offset, so the hygroscopicity of wool fibre integral body changes little.
Embodiment two: composite finishing agent arrangement
1, hydrophilic finishing agent and silicone oil 818 composite finishing agent arrangements
In the composite dressing liquid of following ratio preparation silicone oil 818 with hydrophilic finishing agent.
Silicone oil 818: hydrophilic finishing agent 1=1:1,2:1,3:1,5:1;
The wool sample put into the composite dressing liquid for preparing and handle, then at 80 ℃ of oven dry 30min and be placed in the balancer of standard humidity (RH 75%) balance and measure moisture absorption weight after 24 hours down by infusion process 3.
Composite finishing agent consumption: 8%owf;
2, the composite finishing agent arrangement of hydrophilic finishing agent, nano material and adhesive
The composite dressing liquid that it is good that the wool sample is put into emulsification is handled by padding method.Then at 80 ℃ of following oven dry 30min and be placed in the balancer of standard humidity (RH 75%) balance and measure moisture absorption weight after 24 hours.
By above-mentioned data as can be known, the titanic oxide nano consumption can not add too much, otherwise can influence the hygroscopicity of wool. and from theory analysis, because of no hygroscopicity group in the titanium dioxide structure, so nano powder adds many more, the hygroscopicity of wool is just poor more.
3, the mensuration of wool antistatic behaviour
| Sample | The wool of different disposal | Electrostatic potential (V) | Half-life (s) |
| 1 | Blank sample | 3122 | 2.3 |
