Description
Technical field
Present invention relates in general to arrangement to textiles, in particular to being suitable for giving the preparation or the reagent of desired properties to textile fabric or by the manufactured goods of textile fabric, described product for example, textiles, knitted fabric or nonwoven fabric.
Type is that aqueous formulation with organo-silicon compound is applied on the fiber and gives these fibers a kind of hydrophilic and softening arrangement result with this under the textile finishing preparation of the present invention.
Consider that from another point of view the textile fabric of arrangement involved in the present invention or textile fabrics have good feel and show required hydrophily simultaneously.
Background technology
Organo-silicon compound are widely used in arrangement and improve yarn and textiles.When organo-silicon compound according to they structure and modifications when being used for this purpose separately, the reagent that can be used as softening agent, defoamer, water-repelling agent, sizing agent (sizing agent) and be used to improve feel.
Because therefore the possibility of using organo-functional group that organosiloxane is carried out modification can make organosilicon be applicable to required application purpose.
A large amount of patent documentations relate to the possibility of use by the dimethyl polysiloxane and the polysiloxanes of other organic group modifications.As the representative of these documents, referring at " textile finishing " (" Textilveredlung ") magazine, 20 (1985), one piece of survey report that the 8-12 page or leaf is delivered.
Goal of the invention
Main purpose of the present invention is the reagent or the preparation of the product finding and be provided for finishing textile fibre or contain textile fabric, and described reagent or preparation can improve the feel of fiber or fiber product, and make their hydrophilings (hydrophilize) simultaneously.Even the free end yarn for firm twisting (firmly twisted) also can make feel be improved.With regard to this purpose, importantly said preparation makes textiles fully wetting, and in the infiltrated fiber composition.Even when arrangement hydrophobicity textile material, also should guarantee wetting and infiltration.Except textile material is had the excellent handle, said preparation also should make them have good hydrophilicity, can dye without difficulty or chromatography (overdye) with textile fabric or the textiles of guaranteeing to put in order again.
Another object of the present invention is that required finishing agent is the aqueous formulation form with high dyebath stability.Even this means after long term storage and in use, particularly in the use after the dilution, finishing agent can layering yet, and the conventional finishing auxiliaries of they and other is compatible.
Another object of the present invention is to provide feel with improvement and highly hydrophilic textile fabric and fiber product.
Another object of the present invention is to provide a kind of method to make fiber and fiber product have the arrangement result of above-mentioned performance.
In general, the objective of the invention is to improve the skill of finishing fiber and fiber product.
Summary of the invention
Surprisingly, use following liquid preparation to obtain required performance combination, described preparation comprises:
0.5-80 the modification organopolysiloxane A of weight % and the mixture of B, wherein the weight ratio of A: B is 10: 1 to 1: 1, wherein organopolysiloxane A is the line style siloxanes that contains polyether group and have at least 40 dialkyl group siloxy units, connect at least two polyether groups on it, the molecular weight of each polyether group is 600 to 4,000 and comprise the oxygen ethylene unit of 40-100 mole %, all the other are the oxypropylene unit, the dialkyl group siloxy units compares more than or equal to 8 with the quantity of polyether group, and wherein
Organic polysiloxane B is the line style siloxanes that contains quaternary ammonium group and have at least 20 dialkyl group siloxy units, described siloxanes is connected with at least two quaternary ammonium groups by carbon atom, and the dialkyl group siloxy units compares more than or equal to 10 with the quantity of quaternary ammonium group.
Said preparation preferably includes:
0.5-80 organopolysiloxane mixture A and the B of weight %, the water of 20-99.5 weight % and/or water miscibility organic solvent.
The linear polysiloxanes that contains polyether group is known already, and is used for the textile finishing purpose to improve feel and to be used as wetting agent.The also known organo-silicon compound that contain quaternary ammonium group of prior art can be used for reducing the static on the textiles.
Yet unexpected and surprisingly, the mixture of now determining the organopolysiloxane A (the line style siloxanes that contains polyether group) of above definition and organic polysiloxane B (the line style siloxanes that contains quaternary ammonium group) has the not available performance with regard to the use separately with regard to two component A and B.Even the prior art of considering, this cooperative effect also are beat all.
As more detailed confirmation in the following embodiments, the cooperative effect of reagent of the present invention or preparation comprises the remarkable improvement of feel, even after the washing cycle through soft (delicate) for several times, this improvement is also remained to a great extent.The ability of making of the textiles of handling is improved in surprising especially mode.This shows as required power of pin of insertion and reduces greatly.The suture needle damage (stitch damage) of making in the process reduces greatly.The ratio resistance (mass resistance) of weighing the static arrangement improves.Textiles with reagent arrangement of the present invention does not have spot.When in dyeing installation, handling, realized bathing completely dying exhaustion (bath exhaustion).
Other finishing agents of effective dose can be added in the preparation of the present invention.The example of conventional finishing agent is: contain to some extent must acidic catalyst subtract wrinkle resin (wrinkle-reducing resin), fluorescent whitening agent and filler.
The organopolysiloxane A of modification and B can be dispersed in the water under the situation of not adding exogenous emulsifying agent.Form clarification by this way to slightly turbid colloidal solution.No matter how its concentration of these aqueous formulations all is stable, promptly they are under the liquid storage form or all be stable under the solution form of diluting at using situation; Even and they are also not stratified after long term storage.
