Keilim28: 10
סְבָכָה שֶׁהִתְחִיל בָּהּ מִפִּיהָ — טְהוֹרָה עַד שֶׁיִּגְמוֹר אֶת קוּרְקוּרְתָהּ. הִתְחִיל בָּהּ מִקּוּרְקוּרְתָהּ — טְהוֹרָה עַד שֶׁיִּגְמוֹר אֶת פִּיהָ. שָׁבִיס שֶׁלָּהּ — טָמֵא בִּפְנֵי עַצְמוֹ. הַחוּטִין שֶׁלָּהּ — טְמֵאִין מִשּׁוּם חִבּוּר. סְבָכָה שֶׁנִּקְרְעָה, אִם אֵינָהּ מְקַבֶּלֶת אֶת רֹב הַשֵּׂעָר — טְהוֹרָה.
[Concerning] a hairnet, [if] one began [to make] it from its rim, it remains tahor until one finishes its bottom. [If] one began from its bottom, it remains tahor until one finishes its rim. Its frontlet is tamei by itself. Its strings are tamei because they are [considered] attached [to it]. [If] a hairnet became torn, if it cannot contain a majority of the hair, it is tahor.
