Abstract: A process for producing a thermoplastic resin capable of giving a molded article having a very good appearance, by coagulating a thermoplastic resin latex prepared by an emulsion polymerization method which comprises making the latex into a coagulated slurry by carrying out the coagulation procedure in a range of temperatures lower than the solidifying point of the thermoplastic resin, adding an alkaline substance to said coagulated slurry in a range of temperatures lower than the aforesaid solidifying point so that the pH of said coagulated slurry is adjusted to a pH 0.1 or more higher than its pH at the time of the coagulation and that the pH of the whole coagulated slurry after the addition of the alkaline substance is adjusted to 7.0 or lower, and then raising the temperature of said coagulated slurry to solidify the coagulated particles.

Abstract: A screw-type hydro-extracting extruder comprising a raw material supply zone, a hydro-extracting zone and a heat-melting zone, said hydro-extracting zone is comprised of a plurality of doughnut-shaped plates and a slit is formed between every two adjacent plates.

Abstract: There is disclosed a method for treating an emulsified latex which comprises discharging an emulsified latex containing particles of 1 .mu.m or less in diameter into a coagulation solution from fine tubes which satisfy L/D.gtoreq.0.065 Re (L: length of fine tube, and D: equivalent diameter of fine tube and Re: Reynolds number) at a Reynolds number of 300 or less to coagulate the latex and washing and drying the coagulated latex to obtain a particulate of high bulk specific gravity containing substantially neither fine powders nor coarse particles or a pellet-like molded product.

Abstract: A method of producing water-absorbent cloth-like articles is disclosed. A binderless cellulosic nonwoven fabric is placed in a mold and compressed under a pressure of 1100 to 1500 kg/cm.sup.2, preferably 1200 to 1300 kg/cm.sup.2. The molding so produced will recover to original form when water is added to it.
