Packing for cushions

In addition to feathers and natural fibers, in particular wool, synthetic fibers are also increasingly being used to fill cushions used. Such pillow fillings offer the possibility of particularly easy cleaning, since the pillows without difficulties can be washed, if necessary even in washing machines. .Because the low water absorption capacity of the synthetic fibers the pillows dry quickly.

As fiber material for pillow fillings are due to their physical Properties of polyester, especially polyethylene tereph * thalat particularly suitable.

In addition to the advantages mentioned above, come out with pillow fillings synthetic fibers, however, also have a number of disadvantages. So you can often build up a lump after prolonged use Find out which is not like with feather pillows by shaking them can be undone. In addition, the fiber ends - like the feathers - tend to pierce through the cushion cover

Attempts have been made to counteract these disadvantageous measures by means of various measures To report phenomena, for example by mechanical or adhesive bond slipping of the fibers against each other and thus to push back a lump formation as much as possible.

GW .137? Gbm. '

The object of the innovation is a filling body for cushions, which eliminates the above-mentioned disadvantages © from the outset. The filler body is characterized by a fleece made of endless polyester hollow fibers, in particular hollow fibers made of polyethylene terephthalate, the void volume of which makes up Io to Jo fo and which has a crimp of 50 to 12o arcs per Io cm, preferably 65 to 100 arcs per Have Io cm.

The fillers according to the innovation are particularly soft and voluminous and also considerably more dimensionally stable than fillings made of fibers. Both when the hollow fiber fleece is deposited in winding form as well as in a large number of layers, you can avoid that by placing the beginning or end of the fleece inside Thread ends lie on the surface of the filling and can pierce through the casing. But even if you click on it If measures are not taken, there is a risk that the thread = ends step through the cushion cover, considerably less than with fiber fillings »

The polyester tow, which is prepared from the webs _p may be crimped by any known method, but preferably it applies a compressive crimping "

After the crimping process and the usual fixing of the crimp the thread cables are opened to form a fleece and laid down in layers or opened in a winding form,

The void volume of the individual threads and the number of crimped arcs within the specified limits are important for the good properties of the packing elements. If the void volume of the threads is less than 10% or more than -jo % , the bulkiness and bulkiness are adversely affected. Hollow threads with less than 10% void volume practically do not differ from normal filaments in terms of their properties, while with a larger void volume of more than 30 % the tendency of the filaments to lay flat during the stretching or crimping process and to assume a ribbon-like character is the voluminoside fleece affected to an even greater extent "

GW IJJJ Gbm.

To achieve optimal properties, the number of crimped arcs should be within the range of 50 to 12o arcs per 10 cm, where every change in direction of the thread counts as an arc, ie * a sinusoid counts two arcs. There are practically no restrictions with regard to the thread denier, but one will generally choose a denier between 0.5 and 20 denier, preferably between 3 and 8 denier.
