TEXTILE FINISHING Talc U used in the back-filling o f cotton goods at the finishing m ills. P rin c ip a l requirem ents are w hiteness of color, freedom from abrasiveness, and fineness of grind. SIERRA SPECIAL TEXTILE TALC meets a l l .h e requirem ents. It is m aintained to a high standard of quality fo r th is industry. SIERRA SPECIA L T E X T IL E TALC is produced from our softest talcs which accounts for its low grit content and freedom from abrasiveness. It reduces the tendency o f filled goods to dull the cutting knives and cause needle heating. It im parts p ro p e r viscosity to the starch m ix tu re w ithout th in n in g . It fills the th read lattices th o ro u g h ly leaving no pin-holes. It assures a smooth, velvety finish. SIERRA FIT'RE RE TAt C is also offered to the Textile trad e where still greater whiteness is required. SIERRA KI-GRARE is suggested w hen m axim um chem ical parity is required.

T h e ta lc m u st be re la tiv e ly low 'in grit content and have good filling and covering characteristics. Talc has several distinct advantages over o th er m ineral fillers. It im parts from 10% to 25% greater m ineral retention th an clay, m aking it superior for heavily filled papers such as order form s, offset paper, and book stock. It is norm ally b righter, lightens the pulp, imparts greater m oisture resistance, and adds greater strength. It ia superior to clay in the better grades of w riting papers because it m akes a less absorptive paper. Talc is an excellent ex ten d er o f titanium dioxide in coated papers and board stock. It is ideal for wax coated stock due to its translucency and smoothness. T h e follow ing a re S ierra's leading p a p e r m ak ers grades: T H I L I I Y S t^ t t r . f 11.

It is com patible with m ost of the killers and releases the toxic base quickly. O ther extenders are volcanic ash, pyrophyllite, diatomaceous e a rth , a n d clays. All o f these, except clay, are highly abrasive and cause excessive wear to the spray equipm ent. Clay has a tendency to "hall u p " and the flowing characteristics are therefore poor. Talc is non-abrasive, soft, sm ooth, and flows readily. S ierra p ro d u ces two excellent talcs for this uses S i r .L F ;/ . W fr. n t TALC " t r . " T h is is a soft talc (m agnesium silicate) o f the steatite variety. It is the sm oother and better flow ing o f the two talcs an d is ideal for sulphur, nicotine, etc. n r CUtC is a unique m ineral of the talc family, being a m agnesium alum inum silicate. It wets m ore easily and has g re a te r adhesiveness. It is less alkaline and has m et with approval as a carrier particularly for DDT and the newer chem ical killers. SOAP MANUFACTURING Talc is used in only the filled hand and laundry soaps, cake, flakes, and powder. . Its principal function is as a filler and an extender. SIERRA WHITE - 20 0 end SURF:L SHOW TALCS are the two recom m ended grades.
