ותולעת שני, wool dyed red is called תולעת. The colour itself is called שני. We know this from Nachum 2,4 אנשי חיל מתולעים, “soldiers dressed in crimson.” The word also occurs in that sense in Lamentations 4,5 האמונים עלי תולע, “the ones who used to be robed in purple, etc.” The prophet Isaiah 1,18 holds out the hope that “if our sins were staining our clothing red, repentance would result in their becoming white as snow.” The prophet considers both the word שלג and שני as dyes, the former being a white dye, the latter a red dye. However the words תולע and צמר both refer to wool, the latter being undyed wool.
Malbim
And she went down (Shemot 2:5). Now, the reasons for which God presented him that he would be saved will be told: that he would be "reared in purple" (Eicha 4:5) in the king's house, but despite all this his people and his tribe would recognise him.
1. God invited bat Par'oh - regarding whom, "all the glory of the king's daughter is within" (Tehillim 45:13) - and "she went down" from her height "to wash in the Y'or", in an open place and a public thoroughfare. For if it weren't, his sister [Miryam] wouldn't have been able to reach her.
2. That her young women weren't directly with her - she would have been afraid before them to transgress her father's commandment and save those given to death.
3. "And she saw the ark" (Shemot 2:5) and wasn't it also that God may They be blessed was within the reeds, concealed and covered by the reeds.
4. That she took it by means of her slavegirl - the lesser one, that she wasn't embarassed to do anything she wanted in front of her. And there's a difference between young women [ne'arot] and slavegirls [amahot]: young women are given to her as a staff and they're honoured and the daughters of dignitaries, and slavegirls are lesser and stand in her service.

Radak
From the dunghill (ashpot): It is singular with the construct of achot (sister), which when it is complete (plural) is achiyot. And the gathering [of dunghills) is (like in Lamentations 4:5), "embraced the ashpatot," in exchange for the accent being soft.
