Abstract

The present invention is for method by manufacture of shaped cushions or filling material for furniture and seats where a filling material being a wad is filled into an enclosing cover which comprises fibres of a material having a lower melting point than the wad. Preferably the cover is entirely made from fibres having a melting point below 100 oC. The wad may comprise fibres having two different melting points and the cover may be divided into several separate sections which are intended to be filled with different materials and/or packing density.

Description

| . . | .1 G1 -v-S N , UT a) --¥ .ån egenskaper hos olika delar av produkterna. Genom uppfinningen blir det möjligt att formgjuta polyesterfiberprodukter. | . . | .1 G1 -v-S N, UT a) - ¥ .ån properties of different parts of the products. The invention makes it possible to mold polyester fiber products.

Vid utövande av uppfinningen framställs fodral av non-woven-material med smältpunkt under 100°C.In the practice of the invention, cases are made of non-woven material with a melting point below 100 ° C.

Fodralet fylls därefter med en blandning av 10-30 vikt-%, företrädesvis ca 20 vikt-% smältbar flber och 70-90 vikt-%, företrädesvis ca 80 vikt-% polyesterfiber av ett material som är osmältbart eller inte smälter vid de temperaturer som förekommer i processen. Fyllningen kan ske på känt sätt med vakuum. Det fyllda fodralet placeras därefter i en form som tillåter uppvärmd luft att strömma in i och genom fodralet och fyllnadsmaterialet. Luftens temperatur är 120-170 °C, lämpligen 130-160 °C och företrädesvis ca 135 °C. Luftgenomblåsningen pågår under en tid av 20 s - 10 min, vanligen 30 s - 5 min och företrädesvis 30 s - 1 min. Härvid smälter dels det omgivande höljet och dels de smältbara fibrerna i fyllningen. Detta resulterar i kuddar av homogent material med mycket god formhållfasthet. Även textilier kan på detta sätt gjutas fast och bilda en homogen enhet med stoppningen. Volymvikten hos den färdiga produkten kan varieras i ett intervall av åtminstone 20-50 kg/ma. Detta kan utnyttjas genom att olika kanaler eller delutrymmen i ett fodral fylls till olika volymvikt vid tillverkning av exempelvis stoppningar för bilsäten, där en mjukare mittendel utgör ryggstöd och/eller sits och fastare sidodelar bildar stödvalkar på ryggstödets och/eller sitsens sidor. u» .. J. ...The cover is then filled with a mixture of 10-30% by weight, preferably about 20% by weight of fusible fibers and 70-90% by weight, preferably about 80% by weight of polyester fiber of a material which is indigestible or does not melt at the temperatures which occurs in the process. The filling can be done in a known manner with a vacuum. The filled sheath is then placed in a mold that allows heated air to flow into and through the sheath and the filling material. The air temperature is 120-170 ° C, preferably 130-160 ° C and preferably about 135 ° C. The air purge lasts for a period of 20 s - 10 min, usually 30 s - 5 min and preferably 30 s - 1 min. In this case, the surrounding casing and the fusible fibers in the filling melt. This results in cushions of homogeneous material with very good dimensional strength. Textiles can also be cast in this way and form a homogeneous unit with the padding. The bulk density of the finished product can be varied in a range of at least 20-50 kg / ma. This can be used by filling different channels or sub-spaces in a case to different volume weights in the manufacture of, for example, upholstery for car seats, where a softer middle part forms the backrest and / or seat and firmer side parts form support rollers on the backrest and / or seat sides. u »..
