Abstract: A SELF-CRIMPABLE COMPOSITE FILAMENT YARN COMPRISING AT LEAST SINGLE FILAMENT COMPOSED OF TWO KINDS OF THERMOPLASTIC HIGH POLYMERS HAVING DIFFERENT VISCOSITIES AND ARRANGED IN AN ECCENTRIC DISPOSITION IN THE CROSS SECTION OF EACH FILAMENT, MATERIAL HIGH POLYMERS SHOULD BE CHOSEN FROM POLYESTER GROUPS AND THE DIFFERENCE IN VISCOSITIES THEREOF SHOULD BE LARGER THAN 0.05%. A CREPE FABRIC CONTAINING THE FILAMENTS CAN BE PROVIDED WITH REMARKABLY IMPROVED PEBBLES.

Abstract: A POLYESTER COMPOSITE MULTIFILAMENT YARN COMPOSED OF A PLURALITY OF INDIVIDUAL FILAMENTS HAVING COMBINED PROPERTIES OF THE SHRINKING PROPERTIES RESTRICTED AS FOLLOWS.

PERCENT

(1) A RANGE OF APPARENT SHRINKAGE WHEN THE YARN IS TREATED IN HOT WATER AT A STRETCHED CONDITION OF APPROXIMATELY 5 MG./DENIER 0-20 (2) SUBSTANTIAL SHRINKAGE WHEN THE YARN IS TREATED BY THE SAME MANNER AS IN CASE OF MEASURING THE APPARENT SHRINKAGE OF YARN LOWER THAN 3

THE ABOVE-MENTIONED COMPOSITE MULTIFILAMENT YARN CAN BE ALSO DEFINED WITH RESPECT TO THE DENSITY OF FILAMENT, OR NUMBER OF CRIMPS AFTER TREATMENT IN BOILING WATER. THE PREFERABLE CONDITION OF THE DENSITY OF FILAMENT IS RESTRICTED AT MORE THAN 1.3850 WHILE THE NUMBER OF CRIMPS IS RESTRICTED A RANGE FROM 10 TO 35/CM.

Abstract: This invention discloses heat-sensitive stencil paper and a production method thereof. Since no adhesive is used in this paper, the permeability to printing ink is not affected, and thus high-quality prints are obtained. The elimination of the use of adhesive prevents the decrease in resistance to ink, the adhesion to a thermal head, and emission of toxicious chlorine and improves the stability of film coating and productivity. This stencil paper is obtained by thermally bonding a polyester film and a porous support comprising a polyester fiber and co-stretching them, and the peel strength between the film and the porous support is at least 1 g/cm. Accordingly, prints obtained by stencil printing have very high quality.

Abstract: A polyester composite monofilament for screen gauze comprises (a) a sheath part made of a polyester having a glass transition temp (Tg) of 35-73 deg C, and (b) a core part made of a polyester having a higher Tg surface area ratio of (b) to (a) is 70:30-95:5. The strength at break of the monofilament is at least 6g/d and its modulus at elongation of 10% is at elast 3.5 g/d. Pref both sheath and core comprise polyester copolymer formed mainly of polyethylene terephthalate (PET). Pref the sheath component is made by copolymerising at least one of dimer acid, adipic acid, sebacic acid and a cpd of formula R10(CnH2no)mR2 (I) with polyethylene terephthalate. In (I), R1 and R2 = 1-4C alkyl, n = 2-5 and m = 2-250. The monofilament has a concentric core/sheath structure, has a denier less than 9 or it may have at least 5 cores, each core having a strength of at 3d.

Abstract: Highly oriented undrawn polyester fibers show a diffraction peak, due to crystals of the polyester, observable in a wide angle x-ray diffraction image of the fibers and having a birefringence of 0.015 to 0.05. A process for preparing highly oriented undrawn core-sheath type conjugated polyester fibers which may have such diffraction and birefringence properties comprises the step of spinning a polyester as the sheath polymer and a polymer having a gradient of elongational viscosity with temperature larger than that of the sheath polymer, at a spinning speed of 4000 to 12000 m/min. The fibers may be falsetwisted to obtain a textured yarn.
