Definitions

  • the present invention relates to a heat-sterilizable blanket which is characterized by good thermal insulation properties and preferably also by light weight and is intended for use in hospitals, homes, in particular old people's homes, shelters, etc., and a method for producing this blanket.
  • Blankets that are to be used in hospitals or hostels must on the one hand have at least one surface that can be sterilized and on the other hand have good heat insulation properties in order to be able to cope with a blanket at normal room temperature.
  • the ability of the surface to be sterilized by heat or a cooking process with simultaneous, good heat insulation ability could only be achieved by attaching suitable sterilizable coatings, which increased the weight of the blanket and meant a lot of work when it was changed frequently.
  • This increased weight plays a major role especially in hospitals and old people's homes, since patients who are sensitive to pressure, particularly on the extremities and who cannot tolerate heavier blankets, must also be cared for here.
  • the requirement for light weight and good thermal insulation was also not compatible with the requirement for skin friendliness and good absorbency, which can only be met by a surface made of cellulosic fibers.
  • DE-OS 28 50 474 is also the construction of a double fabric made of synthetic fibers, e.g. can be used for ski clothing, in which a filler w.o. is integrated like a pique at regular intervals and has a latent ripple. This crimp is developed by means of a wet finish following manufacture and then fills the voids between the layers. Cookware and sterilization of such materials is naturally not intended.
  • the present invention has for its object to provide a blanket which can be heat sterilized as a whole, and without a separate coating, by washing at the cooking temperature and drying at a correspondingly high temperature, and yet with such a good, also over numerous, washes resistant, thermal insulation ability that it can be used as a single blanket at normal room temperature and does not require a further heat-insulating cover. It should also be absorbent and skin-friendly and preferably have a light weight in order to also be suitable for sensitive patients.
  • This task could be solved by a blanket made of yarn in a double fabric with a hard-wearing upper and lower layer cellulosic fibers a little twisted, crimped filler from a synthetic fiber yarn is pique-like, whereby this blanket bulges, especially after washing, and thereby maintains good thermal insulation properties.
  • the present invention accordingly relates to a heat-sterilizable blanket with good thermal insulation properties, in particular for use in hospitals, homes or hostels, consisting of a regularly tied double fabric with an interposed filling weft, which is fixed at regular intervals by a pique-like binding of the two layers of the double fabric that the upper and lower layers of the double fabric consist of strong twists woven from plain weave from high-strength cellulosic fibers and that a slightly twisted, uncrimped synthetic fiber yarn with a thickness of 100 to 1000 tex serves as an interposed filling wobble over long distances.
  • both the top layer and the bottom layer consist of a skin-friendly, absorbent material, so that a coating is no longer necessary.
  • a cotton thread is preferably selected for these layers, and for decorative reasons the top layer can also be kept in a color that is true to cooking.
  • the thermal insulation ability of the blanket according to the invention is imparted by the filling weft in between, which due to the selected pique-like weave is freely movable over longer distances within the double fabric and therefore after the first boil washes in which both the cellulosic fibers and the synthetic fiber yarn used for the filling weft shrink , bulges and gives the ceiling the desired thickness while increasing the pore volume.
  • This bulking effect is particularly pronounced when the synthetic fiber yarn, which is not crimped and has no latent crimp, has a thickness of 200 to 500 tex.
  • all synthetic fibers that can be used for textiles are such as polyester fibers, polyacrylonitrile fibers or polyvinyl chloride fibers.
  • polyester fibers polyacrylonitrile fibers or polyvinyl chloride fibers.
  • Yarns made of polypropylene have proven particularly useful here, since they are not only very light, but also have a very good building effect.
  • Polypropylene yarns with a thickness of 250 to 333 tex are particularly preferred as fill weft.
  • cavities are best obtained when choosing a waffle pique-like binding, and it is particularly preferred to choose a weapon pique that is stretched in the warp direction from the weft direction.
  • the cavities in the warp direction preferably have a length of over 5 mm, for example about 1.8 to 2.5 cm.
  • bonds are also suitable which produce hollow tissue-like character by filling filler insertion.
  • FIGS. 1 to 4 An example of a double-woven construction with a pique-like filling fill that has proven particularly useful for the blanket according to the invention can be seen in FIGS. 1 to 4.
  • 1 means the top wefts, 2 the bottom wefts, 3 the top warps, 4 the bottom warps and 5 the fill wefts.
  • the dashed and solid lines each show the threads in longitudinal section, the circles indicate the threads in cross-section, with the numbers in the circles indicating the number of weft and warp threads.
  • Figure 1 shows a chain cut after the binding cartridge at a point where the topstitching 6, which is the pique-like character, can be seen. This section shows the 1st, 2nd, 3rd and 4th weft as well as the 1st to 24th warp.
  • FIG. 3 is a weft cut at the 1st to 4th warp thread, which extends over the 1st to 8th weft thread. Here you can see both the topstitching 7 and the 9th and 10th filling section 5. From the 5th to the 24th warp thread, the weft cut gives the picture which is shown in FIG. The filling weft threads 5 and their free floatation can also be seen here, but no stitching.
  • the fabric formed from upper weft 1 and upper warp 3 or lower weft 2 and lower warp 4 remain unattached over long distances, which together with the floating floating weft 5, which shrinks when washed at cooking temperature, gives the building effect.
  • Another object of the present invention is a method for producing the heat-sterilizable blanket according to the invention, according to the upper weft and upper warp as well as lower weft and lower warp, each made of solid twine from cellulosic fibers, which are bound in plain weave, together with the uncrimped synthetic fiber yarn of a thickness of 100 to 1000 tex can be processed as a filling weft to form a regularly tied double fabric with an additional pique-like filling weft. Since both the cellulosic fibers and the synthetic fibers used for the filling weft shrink during cooking, the subsequent shrinkage must be taken into account when choosing the dimension of the raw blanket.
  • the final dimension of the blanket has set.
  • the building effect also occurs, which is particularly favorable for polypropylene as a material for the filling weft, so that blankets of a thickness of approximately 3 to 5 mm can be obtained, although in principle they consist of only two layers of cotton.
  • the shrinkage of the blanket is about 9 to 12% in the warp direction by the first cooking treatments, but in the weft direction it is about 13 to 17%.
  • the yarns used can be produced by all common spinning processes.
  • a yarn size of about 85 to 25 tex, preferably about 30 tex can be used.
  • the yarn for the filling weft can also be produced on conventional spinning machines, such as open-end spinning machines or ring spinning machines, whereby excessive twisting or twisting should be avoided, since the yarn would otherwise curl, which is undesirable.
  • the woven raw blanket can then be edged in any conventional manner, such as quilting or binding.
  • the blanket according to the invention offers significant advantages, in particular in companies in which a frequent change is required. Above all, there is complete hygiene, since the entire blanket can be boiled out after every change. It also helps to save work because it can be used without any coating due to its washability and skin-friendly features. If it is carried out with polypropylene as a filling shot, it is very light with good thermal insulation properties, so that it is well tolerated by sensitive and frail people, for example seriously ill or injured patients in hospitals or inmates of old people's homes. The absence of a coating is also a significant advantage in terms of weight. Due to the type of weaving technique, the blanket is also porous and therefore breathable. After all, it is characterized by its particular durability, because no easy-to-remove quilting is necessary and the surfaces can be made from sturdy threads that can easily handle many washes.
