Title: Filament yarn comprising multi-component fiber and production thereof and fiber surface structure comprising therefrom
Inventor: HAINTSU RINHARUTO
IPC: D02G1/02
Filed: 1981-09-24
Abstract: Filament yarns composed of multicomponent fibers of the matrix/segment type are produced and processed into textile fabrics by false-twist texturing the multicomponent fibres made up of segments of varying deniers to cause softening the matrix to bond the filaments together over short, medium or longer sections of the yarn. After conversion of the yarns into fabrics, the fabrics are subjected to a shrinking treatment. The fabrics so treated have a reduced tendency to crease or wrinkle, better crease recovery and better dyeing properties. The denier of the lower denier segments should be finer than 0.6 dtex and the denier of the high denier segments should be at least 1 dtex; the weight ratio of low to high denier segments in the yarn ranges from about 25:75 to about 75:25. The matrix is preferably made of polyamide 6 while the segments are polyethylene terephthalate. The cross-sectional shapes of the fibers may e.g. resemble a toothwheel with fine peripheral segments and a coarser core, combinations of three-toothed wheels with 12 or 6 peripheral teeth or similar combinations of orange-shaped cross-sections such as 3 and 6 "slices".

Title: Manufacture of composed product
Inventor: TAKAHASHI SHINICHIROU
IPC: B29C45/00
Filed: 1979-11-19
Abstract: PURPOSE: To enable smooth rotation by composing a base body and a rotary body rotatably with each other through molding thereof from synthetic resin and by eliminating a molding flash on the rotating surface.  
     CONSTITUTION: Melted synthetic resin such as ABS resin containing glass is injected into molding dies consisting of the 1st cavity 6 and a core 7 to form a chassis 1 and a retaining part 3 monolithically. Next, the core 7 being used commonly, the chassis 1 is pressed between the core 7 and the 2nd cavity 10 and thereby the tip of the retaining part 3 is transformed into a conical shape. Under the condition, polyacetal resin is injected into the 2nd cavity 10 and thus the rotary body 2 is molded secondarily. On the occasion, by the heat and the pressure of the mold in the secondary molding, the retaining part 3 is transformed into a conical shape. By this, the rotary body 2 turns to be rotatable within the retaining part 3. In addition, since no molding flash and the like are produced within the retaining part 3 of the chassis 1 which is the primary product, the rotation of the rotary body 2 is smooth.

Abstract: PURPOSE:To improve both an ornamental effect in a cabin and workability by configurating a device in such a way that a skin material is coated first over the inner surface of a mold, then synthetic resin is injected into the mold, and then the inner liner which combines a resin skin with the other skin, is formed while being stuck over the base material through an elastic material. CONSTITUTION:A trim 26 which is provided for a quarter panel of a vehicle, is composed of a base material 28, polyurethane foam 30, and of an inner lining 32. Though the inner lining 32 is composed of two kinds of materials: a PVC skin 34 and a skin material 36, as they are integrally molded, an ornamental effect in a cabin is improved. In combining the PVC skin 34 with the skin material 36, when the PVC skin 34 is formed by a slush molding, the skin material 36 is coated over the molding surface first in advance, then synthetic resin in a sol form is injected into the mold allowing a part of the synthetic resin to penetrate into the skin material 36. Subsequently, the synthetic resin in the mold is heated until to be gelatinized and is allowed to be the PVC skin 34. Thus the skin material 36 in which the synthetic resin is impregnated, can be combined with the PVC skin 34.
