摘要:
A method and apparatus for producing thread or yarn-like material by electrostatically flocking it or covering it with fibers. Grounded base or carrier threads that are provided with adhesive are moved through an electrostatic field of high voltage, where the surfaces of the carrier threads are flocked all the way around with pretreated short fibers (flock material). During the course of producing the flocked thread or yarn, selective lengths of the carrier threads are nonuniformly flocked in an irregular sequence, with the flock material, in different flock patterns.

NOVEL COMPOSITE YARN IS PRODUCED WHICH COMPRISES A CONTINUOUS POLYMER SUBSTRATE CONSTITUENT COMBINED WITH FIBRIDS WHICH ARE EMBEDDED WITHIN THE POLYMER SUBSTRATE AND CONSOLIDATED THEREWITH; THESE FIBRIDS GENERALLY PROTRUDE OUTWARDLY FROM THE POLYMER SUBSTRATE CONSITUENT IN THE FORM OF FILAMENTOUS UNITS HAVING AN AVERAGE LENGTH OF FROM 1/8 TO 1/2 INCH AND A FINENESS OF BETWEEN 0.2 AND 1 DENIER AS WELLL AS A CHARACTERISTIC SPECIFIC SURFACE ABOVE 2 M.2/G; THEY IMPART TO THE COMPOSITE YARN A FIBROUS SURFACE TEXTURE; THIS NOVEL YARN IS PRODUCED BY A PROCESS GENERALLY INVOLVING EXTRUSION OF THE POLYMER SUBSTRATE AND COMBINATION AS WELL AS CONSOLIDATION OF THE EXTRUDED SUBSTRATE WITH THE FIBRID UNITS THROUGH PRESSURE AND COOLING.

Disclosed are composite elastomeric yarns comprising a polymeric core, a thermoplastic polymeric sheath disposed about the core and fibers disposed about and mechanically anchored in the sheath. The melting point temperature of the material comprising the sheath is at least about 10° C. and preferably from about 50° C. to about 75° C. lower than the melting point temperature of the material comprising the core. Methods and articles relating to such yarn are also disclosed.

Compound threads (1) and the fabrics obtained therefrom are very inexpensive, of acceptable quality and preferably useable to make recyclable disposable garments. Said threads (1) include a thin carrier thread (2) to which a web mass (3) coming from the carding of the fiber used, is adhered preferably by means of use of a water-soluble glue or electrostatic means.The compound thread (1) has the possibility of making use, upon making the web (3), of the shortest fibrils that are usually disposed of.One of the fabrics obtained consists of a band or strip of web (3) that includes several carrier threads (2) placed parallel to each other and that can be cut to obtain compound threads (1.)Another fabric consists of weft thread and crossed warp thread of which all or some, depending on the different combinations, are compound threads (1.)
