Definitions
- the instant invention makes it possible favorably to change the surface structure of the fibers or filaments and simultaneously to achieve a dulling thereof.
- pilling effect refers to the slow but continuous loosening of individual fibers from the surface of the fabric. The result thereof is a rolling together or intertwining or felting of the gradually protruding fibers in the form of knobs.
- the polyamide fiber be treated with monohydric or polyhydric alcohol solutions or with metallic salt solutions such as zinc chloride solutions or magnesium chloride solutions.
- monohydric or polyhydric alcohol solutions or with metallic salt solutions such as zinc chloride solutions or magnesium chloride solutions.
- fibers made of polyethylene terephthalate do not emerge satisfactorily from such after-treatments.
- polyethylene terephthalate fibers be wetted with highly concentrated solutions of caustic soda. The result of such treatment is merely the production of a dulling effect. A reduction and much less an elimination of the pilling effect, cannot be obtained by that treatment.
- polyethylene terephthalate fibers may be simultaneously roughened and dulled by a novel after-treatment.
- polyethylene terephthalate containing from 5% to 30%, preferably 7% to 12% of the solvent is spun in accordance with conventional techniques and the still warm fibers containing solvents are guided through a short distance in the air.
- the fibers are then conducted through an aftertreatment bath of organic liquids, the effect and purpose of which is to dissolve or extract the solvent contained in the outer layer of the fiber.
- solvents which m y be employed in carrying out the solvent-condensation of ethylene glycol terephthalates there are for example: diphenyl methane, diphenyl oxide, diphenyl,
- Suitable agents or means for effectuating the aftertreatment are characterized by the feature that: (a) they do not dissolve polyethylene terephthalate fibers, but (7;) do possess the property of dissolving or extracting the aforesaid residual solvents present in the outer layer of the fibers.
- agents possessing such characteristics are: carbon tetrachloride, tetrachloroethylene, acetone, tetrahydronaphthalene, etc.
- Example Polyethylene terephthalate containing 10% of alphamethyl-naphthalene is spun by the conventional melt spinning method.
- the still warm, solvent-containing fibers after passing through a short air gap of about 10 centimeters, are conducted into an after-treatment bath consisting of coldcarbon tetrachloride.
- the fibers are spooled in conventional manner after being withdrawn from the bath and are highly stretched.
- the stretched fibers are then spooled upon perforated rollers and are subjected to a treatment with steam having a temperature of C. whereby the solvent contained in the fibers is expelled.
- the fibers thus produced are strongly dulled and show the desired roughening.
- Method of roughening and dulling polyethylene terephthalate fibers which comprises spinning a molten mass of solvent-containing polyethylene terephthalate into a fiber which retains a portion of said solvent, the solvent in said molten mass being present in an amount of from 5% to 30%, passing the spun fiber through a bath wherein the aforesaid solvent is extracted from a surface layer of the fiber, stretching the so treated fiber, and subjecting the stretched fiber to the action of superheated steam to expel the residual solvent.

- Process of roughening and dulling polyethylene terephthalate fiber which comprises spinning a molten mass of solvent-containing polyethylene terephthalate into a fiber which retains a portion of said solvent, the solvent in said molten mass being present in an amount of from 5% to 30%, extracting the solvent retained in the freshly spun fiber from a surface layer of the fiber by a cold organic solvent, stretching the thus treated fiber, and then subjecting the stretched fiber to the action of superheated steam to expel the residual solvent.
