Definitions
- the invention relates to a method for producing a fabric at least partially split yarns, fibers or filaments.
- Document EP 0 814188 A describes the production of easily cleavable, conjugated fibers known. These are made from two by a spinning process primarily incompatible starting materials such as polyethylene terephthalate and Polyamide spun and can be affected by mechanical forces such as e.g. a water jet treatment can be split into its filaments. From documents JP A 1 00 96119, JP A 2000017519 or JP A 2001181931 are known conjugated fibers and textiles made therefrom, that of two mutually compatible polymers in a spinning process be produced and by a gap treatment in these filaments be split up.
- the object of the invention is to provide a method which the manufacturing process of fabrics made of splittable fibers, yarns or filaments simplified, the degree of splitting increased, or at least partial splitting of mutually compatible polymers allows conjugate fibers.
- the object is achieved according to the preamble by yarns, fibers or filaments which are formed from at least two filaments and which originate from a common spinneret and are formed to form a surface which is at a temperature between the glass transition temperature (T g ) and the melting temperature of the or the polymer (s) used are compressed to at least 10% of the density of the polymer (s) used, so that subsequent mechanical action at least partially results in a splitting into the filaments.
- T g glass transition temperature
- T g glass transition temperature
- the polymer (s) used are compressed to at least 10% of the density of the polymer (s) used, so that subsequent mechanical action at least partially results in a splitting into the filaments.
- conjugated yarns, fibers or filaments of mutually incompatible polymers can be almost completely split into their filaments and yarns, fibers or filaments of mutually compatible polymers at least partially show a split in their filaments.
- the method is advantageously carried out in such a way that the compression at a temperature of up to max. 10 ° C below the melting temperature of the polymer with the lowest melting temperature. This enables a maximum splitting result to be achieved without the yarns, fibers or filaments fusing in the fabric.
- a method in which the starting sheet is particularly preferred to a density of at least 15% of the density of the one or more Polymer (s) is compressed.
- Yarns, fibers or filaments made of mutually incompatible polymers Achieve gaps greater than 99% with a reduction in energy consumption for high pressure water jet treatment. They are opposite one from the State of the art high pressure water jet splitting and Consolidation only requires two treatment stages.
- the compression of the starting fabric is also Made using a roller calender.
- This type of compression leaves integrate particularly easily into a continuous manufacturing process.
- the splitting into the filaments is advantageously carried out by means of a Hydrofluid treatment carried out at pressures of 120 - 500 bar.
- the Hydrofluid treatment at pressures of 120 - 500 bar leads, depending on Composition of the conjugated yarns, fibers or filaments into one at least partially up to an almost complete split into the Filaments and to entangle and solidify the resulting existing fabric.
- the split into Microelement threads lead to flat structures with very small pores.
- melt-spun filaments or alternatively staple fibers are used.
