Definitions
- the present invention relates to additives for the permanent hydrophilization of Polypropylene fibers.
- the surface of plastic products must have special effects that are either not at all or only during the shaping for technical reasons imperfectly or, for economic reasons, have it produced only disadvantageously.
- Such a Effects include improving wettability with polar liquids such as water -
- Technical applications are, for example, in the field of the production of Hygiene articles.
- nonwovens are usually made of synthetic fibers, such as polyolefin or polyester fibers, since these Fibers are inexpensive to produce, have good mechanical properties and are thermal are resilient.
- untreated polyolefin or polyester fibers are suitable for this Not intended for use because they are not sufficiently permeable due to their hydrophobic surface for aqueous liquids.
- the present invention relates to polypropylene fibers which are obtained by mixing polypropylene with an additive, then heating this mixture until it melts and spinning it into fibers by customary processes, characterized in that the additives are reaction products of 1 part of polyethylene glycol with a molecular weight of 400 2 parts of lauric acid or decanoic acid are selected.
- the additives in polypropylene containing materials preferably Fibers, fabrics such as nonwovens, foils and foams are used for permanent hydrophilization. All known polymer and copolymer types are suitable for this purpose Propylene.
- poly (propylene) such as isotactic polypropylene; syndiotactic polypropylene; Metallocene-catalyzed polypropylene, impact-modified Polypropylene, random copolymers based on ethylene and propylene, block copolymers Based on ethylene and propylene; EPM (poly [ethylene-co-propylene]); EPDM (poly [ethylene-co-propylene-co-conjugated Diene]).
- polystyrene resin examples include polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyrene resin, polystyren
- homopolymers and copolymers based on ethylene and Propylene is particularly preferred.
- exclusively polypropylene in one embodiment of the present invention exclusively polypropylene, in a further embodiment copolymers based on ethylene and Propylene, a.
- the alcohol and the Acid components are reacted in a molar ratio of about 1 to 2. Mixtures of the acids can also be reacted with the polyethylene glycol become.
- the fibers preferably contain the additives in amounts of 0.5 to 10% by weight, preferably 0.5 to 5 wt .-% and 1.0 to 2.5 wt .-% based on the fiber weight.
- the processes for spinning are known to the person skilled in the art and are described for example in WO 95/10648 or in US 3,855,046.
- Another object of the invention is the use of described above fibers for the production of textile fabrics.
- the textile fabrics are Nonwovens.
- these textile fabrics are for Use in diapers.
- the individual Wetting test is a suitable simulation. Diapers are usually over a Period worn from 3 to 5 hours, with the inside averaging up to 3 times with urine is wetted. It must then be ensured that a hydrophilic nonwoven based on a otherwise hydrophobic plastic is sufficiently wettable so that the urine through the fleece penetrate and can be bound by the absorber material of the diaper.
- Nonwovens can be produced using all of the methods known in the art for producing nonwovens, such as for example in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A 17, VCH Weinheim 1994, Pages 572-581.
- Nonwovens are preferred, which are either were manufactured according to the so-called “dry laid” - or the spunbonded or spunbond process.
- the "dry laid” process is based on staple fibers, which are usually carded into single fibers separated and then using an aerodynamic or hydrodynamic process to be consolidated into the unconsolidated nonwoven. This is then, for example, by a thermal treatment combined to the finished fleece (the so-called "thermobonding").
- Example 1 Preparation of a polyethylene glycol 400 dilaurate
- 180g polyethylene glycol 400 are in the presence of 1.68g Svedcat 3 (Sn organic catalyst of Svedstab) with 155.6 decanoic acid.
- the reaction mixture is under nitrogen blanket heated to 100 ° C.
- the water formed is gradually distilled off, the bath temperature is up to increased to 180 ° C. If no more water is separated, the pressure is reduced to 5 mbar and the remaining water was distilled off at 180 ° C. for 45 minutes.
- the reaction is finished if none Water is deposited more.
- SZ 8.7 g KOH / g
- the wetting test is passed if C1 to C3 are less than 5 seconds.
