Definitions

• the invention relates to a quilt filled with polyester fibers and a pillow with down-like properties.
• Quilted beds have an upper and a lower web made of a textile fabric. Between these sheets there is a filling that is used for the thermal insulation of the bed. Good insulation results if the filling material provides the largest possible air cushion. The lighter the material with which the desired air cushion is achieved, the more comfortable the ceiling is classified. Large flake down of ducks and geese serve as high-quality filling material. Beds filled with this down also have a special handle that is perceived as pleasant and of high quality.
• Down beds essentially consist of two sheets sewn together at the edges, which are usually additionally sewn in a chessboard-like manner by longitudinal and cross-stitching, so that chambers are formed into which the filling material is blown.
• the chambers usually ensure an even distribution of the filling material over the surface of the bed. In special cases, a different distribution of the filling material can be achieved by filling the chambers unevenly and / or by stitching other than that in the form of uniform rectangles.
• Polyester fibers are particularly suitable as filler materials, because due to their thermal fixability they have a high level of structural elasticity, which gives the bed a large air cushion both when new and during use. Polyester fibers made to fill bedding are mostly made as hollow fibers to reduce their weight. Siliconization applied to the surface of the fibers also gives the bedding an improved grip.
• Convention fibers cannot be blown into quilted beds in the usual way like down. Quilted beds filled with polyester fibers are therefore generally manufactured in such a way that a voluminous material web of carded nonwoven is formed as the filling material, which is then wound onto a supply roll.
• the so-called quilting machines are now used to pull off the upper and lower cover fabrics and the polyester material web between them from the supply rolls and sew them together in the desired manner.
• Such a device is e.g. B. described in EP 0 406 588 A2.
• Carded fleeces do not have a purely random distribution of the fiber direction, similar to the down, but the fibers are oriented in preferred directions due to the fleece formation process.
• the fibers under the quilting seams are strongly compressed by the seams and therefore do not contribute to the void volume of the bed. This does not happen if the fibers are blown into the previously formed chambers.
• the object of the invention is therefore to provide filled covers such as quilts, quilts, pillows and the like, in which the cassette or the cassettes are evenly filled with blown-in synthetic fibers.
• Another object of the invention is to provide filled covers to provide a handle that comes very close to the special handle of covers filled with down from ducks or geese.
• Another object of the invention is to provide filled covers which have a low basis weight and which have good insulation properties.
• covers filled with blown-in polyester fibers such as quilted beds, quilts, pillows and the like, which are characterized in that the filling is crimped, preferably squeezed gel-crimped, siliconized polyester hollow fibers with a titer of 0.9 to 7 dtex, a cutting length of 8 to 24, contains in particular 11 to 28 mm, and a ratio of crimp (Kl) to the number of sheets per cm (Bg), corresponding to the relationship 3.5 ⁇ Kl / Bg ⁇ 4.5 and a number of sheets per cm Bg of at least 3.0.
• the hollow polyester fibers preferably consist of polyethylene terephthalate.
• Polyester fibers with a cutting length of 14 to 20 mm, in particular of 18 mm, are advantageous.
• the hollow polyester fibers consist of a mixture of titers and / or a mixture of fibers of different staple lengths.
• the fibers can have one or more cavities in cross section.
• the fibers can have round, oval and other suitable cross sections.
• the hollow fibers used in the context of the invention are compression-crimped fibers which can be produced on compression crimping machines known per se.
• crimped fibers can also be used by other methods, for example three-dimensionally crimped fibers. It is essential in the context of the invention that the crimped fibers have a minimum number of crimped sheets per cm, namely at least 3 sheets per cm. In addition, the number of sheets per cm (Bg) must be in a certain ratio to the so-called curl Kl.
• L k is the length of the crimped staple fiber in the relaxed, exposed state and Ly is the length of the same but stretched fiber, ie the fiber is then practically rectilinear without crimping.
• the stretching is carried out using the so-called uncurling force. This is determined in preliminary tests with the aid of a tangent applied to the force-elongation diagram of the respective fiber. This method, which has not yet been standardized, is described in Work Instructions No. 320.010.3 from Trevira GmbH.
• the fiber used in the context of the invention is flat, fine-arched fibers. These fibers have a low value of the ratio Kl / Bg with a large number of sheets.
• Kl / Bg 6.0 4.0 The table shows the comparison of conventionally produced fibers with a crimping with a titer of 4.4 dtex in comparison to fibers of 4.4 dtex used according to the invention. These fibers have a higher number of sheets with a significantly lower Kl.
• the ratio Kl / Bg in the fiber according to the invention is 4.0 instead of 6.0 as in the conventional embodiment.
• filled covers according to the invention represent high-quality products.
• they have a down-like handle that easily withstands a comparison with covers that contain duck or goose down.
• the manufacture of a filled cover according to the invention can be carried out as follows, as will be shown in the manufacture of a quilted bed, as follows.
• the fibers delivered in a compressed bale are opened in a shredder or a fiber opener and blown through a pipeline into a container.
• the fibers are constantly moved in this pressurized container by several rollers.
• the fibers are then pneumatically fed to a scale where the fiber quantity required for a cassette is weighed.
• Each cassette is filled separately until all cassettes of the sewn-down quilt are filled. Finally, the blanket is sewn to the blow hole.
• a pillow can be filled, which can be seen as a single large cassette, which is sewn to the blow hole after filling.
• a duvet cover can also be produced which, like a pillow, has no stitching. Pure cotton fabrics, blended fabrics, cotton / synthetics and polyester fabrics can be used as the upper and lower fabric between which the filling is embedded.
• the thread size used is NM160 to NM50, the thread density in warp and weft is greater than 30 threads / cm.
• the air permeability of the fabrics is max. 60 1 / m 2 s (measured according to DLN 53887).
