Definitions
- the invention relates to a flame-retardant modified hollow fiber with a silicone-free soft-touch finish, and to a method for the production thereof and to the use thereof for fiber-filled products.
- Fiber fillings can be used in many applications, for example for clothes, cushions, furniture, insulation, quilts, filters, upholstery (e.g. in automobiles), sleeping bags, mattress covers and mattresses.
- the hollow fibers used for these applications are hollow fibers which are made flame-retardant by means of phosphorus-containing compounds.
- the hollow fibers used are preferably polyester hollow fibers.

- a silicone-based softener is used according to the prior art, as disclosed for example in WO 2004/007 347 (Trevira GmbH), U.S. Pat. No. 3,271,189 (Hofmann) and in U.S. Pat. No. 3,454,422 (Mead et al.).
- the object of the present invention is therefore to equip flame-retardant hollow fibers with a soft-touch finish which does not impair the flame-retardant properties of the hollow fibers.

- crimping is understood by the following ratio:
- L k is the length of the crimped staple fiber in the relaxed, released state and L v is the length of the same fiber but in the stretched state, i.e. the fiber is then practically rectilinear without any bends.
- the stretching takes place under the application of the so-called decrimping force. This is determined in preliminary tests by means of a tangent applied to the force/extension diagram for the respective fiber.
- the flame-retardant fibers according to the invention may additionally contain further additives which are usually used in the prior art. These are understood to mean in particular antioxidants, stabilizers (e.g. UV stabilizers), matting agents (e.g. TiO 2 , zinc sulfide or zinc oxide), pigments (e.g. TiO 2 ), additional flame retardants, antistatic agents, dyes, fillers (e.g. calcium carbonate), antimicrobial agents, bioactive agents, optical brighteners, extenders and further processing aids.
- further additives which are usually used in the prior art.

- Such additives may be added to the polymer at any point in time during the polymer production or can be applied to the fibers together with the softener.

Transverse flow, radial, asymmetric or other cooling methods may be used. Air is preferably blown on for quenching purposes.

- Textile fabrics according to the invention are for example clothes, the top and bottom covers of the products mentioned above, as well as mattress covers.
- a staple fiber having a hollow profile is spun from the melt in the manner customary for fibers made from the flame-retardant raw material, is cooled by blowing with air, is provided with a customary staple fiber preparation and is deposited in cans for processing on the conveyor line.
- the spun goods are collected together as a fiber tow over an inlet rake and are drawn in by a first septet, consisting of seven rotating rollers, and passed through an immersion bath, where they are temperature-controlled and once again provided with preparation.
- the spun goods are transported onward by a further septet.
- the stretching takes place on the 6th or 7th roller of this septet, or between said septet and a further septet running at a speed that is greater by the factor of the stretching.
- the fiber is crimped in a stuffer box, fixed or dried in an oven and optionally cut. Between the stretching and the crimping, a silicone-free soft-touch finish is added by spraying or by means of an application roller.
