A process for finishing cellulose-containing fibrous material, in which (a) commercially available textile finishing agents are applied to the fibrous material and fixed, (b) the material is subsequently washed and dried, if necessary, and (c) the textile material is after-treated with liquid ammonia. As a result of the after-treatment with liquid ammonia, the mechanical properties of the finished fibrous material, from the textile point of view, and in particular the tear strength and the handle, are considerably improved.

After-treatment of finished, cellulose-containing fibrous materials with

A process for providing textile fabrics, especially polyamide carpeting, with an antistatic finish. The process comprises treating the fabrics with an aqueous film-forming preparation which contains an acid ester of phosphoric acid or phosphorous acid, said ester being derived from an aliphatic diol having an average molecular weight of 400 to 2600, wherein the diol is unetherified or etherified by C.sub.1 -C.sub.4 -alkoxy.

Propylene oxide reaction products

The invention provides a process for the continuous, dry transfer of organic compounds, in particular of finishing and improving agents, to webs of air-permeable organic materials, preferably to textile webs of polyester, polyamide, polyacyclonitrile and/or cellulose by passing the webs and organic compound carriers over a heating means and subsequently over a suction means with the heating being from the carrier side and suction from the web side.

This invention provides an apparatus for the dry thermal transfer of organic compounds, preferably of textile finishing agents, onto webs of organic materials, in particular textile webs and carpets, by means of needle-bearing supports. The apparatus comprises means for:

Dry thermal transfer of organic compounds by needle-bearing support

New phosphorus compounds are provided which correspond to the formula ##EQU1## wherein R.sub.1 and R.sub.2 each denote alkyl with 1 to 6 carbon atoms, X denotes alkylene with 1 to 4 carbon atoms and A denotes phenyl substituted by hydroxyl, alkoxy with 1 to 4 carbon atoms, alkoxy carbonyl with 2 to 5 carbon atoms, phenyl or halogen and n is 1 or 2. These compounds are useful as flameproofing agents for organic fiber material, especially for polyamide, polyacrylonitrile or linear polyester fibers, when applied according to the dry thermal transfer process.

Process for flameproofing organic fiber materials by the transfer process

A process for flameproofing organic fiber material by the dry thermal transfer process is provided. In this process, a preparation is applied to an inert carrier which is then brought into contact with the fiber materials especially polyamide, polyacrylonitrile or linear polyester fibers, thereafter the carrier and the material to be finished are subjected to a heat treatment at not less than 80.degree. C and the finished material is then separated from the carrier. The preparation which is applied in this process contains a halogen compound of the formula

This invention provides a process for the dry thermal transfer of organic compounds, preferably of textile finishing agents, onto webs of organic materials, in particular textile webs and carpets, by means of needle-bearing supports. The process comprises the following steps: 1. applying of a preparation which contains a transferable organic compound to the needle side of the support 2. bringing said needle side of the support into contact with the web, whereby support and web rest against one another, 3. subjecting the support and/or the web to heat until the compound has transferred under atmospheric pressure to the web 4. separating the treated textile web from the support. The invention also provides a suitable apparatus for carrying out said process.

A process for flameproofing organic fiber material by the dry thermal transfer process is provided. In this process, a preparation is applied to an inert carrier which is then brought into contact with fiber materials, such as polyamide, polyacrylonitrile or linear polyester fibers; thereafter the carrier and the material are subjected to a heat treatment at not less than 80.degree.C and the finished material is then separated from the carrier. The preparation used in this process contains a halogen compound of the formula ##SPC1## Wherein A is halogen, hydroxyl, alkoxycarbonyl, halogenoalkoxy or halogenophenyl and X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5 are each halogen, alkyl, hydroxl or hydrogen, but at most one of the radicals X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5 is alkyl or hydroxyl and at least one of the radicals is halogen, and X.sub.1 and A can together be a radical of the formula --CO--O--CO.

Process for flameproofing organic fiber material by the transfer process

An improved dry process for the finishing of organic material, particularly textile material made from natural or synthetic organic fibres ist described, which comprises applying to an inert carrier preparations containing at least one textile finishing agent transferring at atmospheric pressure above 80.degree.C to the organic material, optionally a bonding agent stable below 250.degree.C, water and/or an organic solvent; drying of the said preparation; bringing into contact then of the treated side of the inert carrier with the surface of the organic material to be finished; subjecting thereupon of carrier and the material to be finished, optionally under mechanical pressure, to a heat treatment at a temperature of at least 80.degree.C until the said textile finishing agent has transferred to the material to be finished, and separating of the finished material from the carrier. The advantage of the new process is that, since there is no effluent produced, it is possible to use also textile finishing agents which are not biologically decomposable and it offers the possibility of obtaining finishing effects on the inside which differ from those on the outside surface of a fabric, such as is desired in the practice.
