Abstract
Abstract Process for the production of moldings by pressing textile residual materials with simultaneous gluing, moldings obtained by this process and the use thereof A process for the production of moldings in which a fibrous material is mixed with an adhesive and the mixture is kept in a mold under pressure until the adhesive sets is described. The process comprises employ-ing as the fibrous material comminuted textile residual materials which are obtained during production, during processing and/or after use of clothing and/or home textiles.
The present invention provides a further possibility for utilizing residual materials. The abovementioned textile products can thus be put to renewed use, even after use as specified. In particular, insulating and dumping materials can be built up from the moldings according to the invention.

~h~`~U
Depending on the nature of the ~oiling re~ulting ~rom use, it may be expedient ~irst to chop or tear the 6tarting material coarsely and then to apply the wa~hing or cleaning ~tage mentioned or the combined cleaning process. Further dlminution to 8mall pieces of ~heet, individual pieces o~ the yarn or multifi.lament and al~o individual filament~ can then be carried out.
The comminuted material is mixed inti.mately with an adhesive or binder, preferably such as il3 e~tabli~hed in the building and decor ector~ Preferred adhe~ive~ are customary an~ established products from other field~ of work, the operating temperature of which is below the melting point of the fiber material~ employed. In addi-tion to liquid adhe~ives, pulverulent adhe~ive~ are particularly suitable. It i~ al~o po~ible to use reac-tive adhesives, in addition to pulverulent hot melt adhesives. There are no re~txiction~ on khe choice of adhe~ive in respect of chemlstry. ~hermopla~ti~s which are liquefied by heating and bond the fibrous material after cooling are also partieularly preferably suitable.
The amount of adhe6ive i~ chs~en according to the intended use purpose, the ~malle6t po~sible amount~ of adhesive being aimed for. The amount of adhesive i~
preferably not more than 10~ by weight~ The use of h~t mslt adhesives in ~mall proportional amounts, for example those ba3ed on a copolymer o~ vinyl e~ter, allows renewed xecyclability and i8 therefore particul~rly preferred.
~he mixture of textile products and adhesive i~ spread out to a sheet uniformly according to the later w~ight per m2 and iæ heated in a pre~ until the adhe~ive display~ its full activity. ~he thickness of the ~olding formed follow~ from the platen ~eparation. The preasure is released when the adhe ive has displayed its adhesive power to the extent that no further change in t~i~kness occurs after th~ relea~e~ Wi$h hot ~elt adhesive~, this i8 the case below a certain temperature.

The composition of the t~xtile materi~ based on prov~n textile mixture~ such as are ~u~tomary in the commodity and home textile ~ector. Prefexred examples of ~uch mixtures are re6idual materials o~ polye~ter/cotton 65~/35%, polyester/wool 55%/45~t acrylic/~wool mixtures or also 100~ polyester, cotton, wool, acrylic or vi~cose.
The molding~ thus ob~ainable can b~ employed, in parti-cular, as insula~ing and damping material~ and have k~own textile properties. Thi~ applie~ to, for exa~pl~, the moisture uptake, th~ dimensional stability, the temp~ra-ture properties and the like. Like the corre~ponding textile products, these insulating and damping material~
are comparably insulating and permeable to air and moisture. As with th~ corresponding textile products, thermally insulating, temperature-compen~ating and ~ou~d-damping properties are typically co~bined with one another.
The term "molding" in the context of this invention i~ to be understood as meaning sheet-like material, a8 well as products onto which a certain ~hape corresponding to later use is embossed.
Such insulating and damping material6, which are, for example, 0.5-5 cm thick, are usually flexible and ~elf-. supporting and can be cut. In a~dition, if formulated25 densely, they assume load-bearing fu~ction~, i.e. they can be loaded mechanically beyond accommodation of their own weight.
They can optio~ally be provided with a covering, for example with a decorative, surface. So that renewed recyclability i8 not limited, such a decorative sur~ace will preferably be achi~ved on the ba~is of textile products, such as, for example, by the use of non-woven~, woven fabrics, knitted fabric~ or laid fabric~
For th~ insulating ~ector~ covering with a waterproof -h ~iJ r~
~urface, permeable to vapor if required, i~ preferred, such a~ i~ cu~tomary, for example, with conventional mineral damping substance~.
The shaped article according to the invention can have ~
surface covering on either one or both ~ide~. A eurface covering on one ~ide will pxeferably ~erve to Lmpart an additional pxoperty, ~uch as modification of the decor-ation of the ~urace and/or Lmpermeability thereof ko water r while ~urface cov2ring on both ~i.dea can help to make a ~ub3tantial c~ntribution to stiffening the product.
A particular type of product ~tabilization i5 poeæible i~, or example, stabilization inside the insulating and damping material i8 effected approximately centrally by mean~ of a laid fabric or woven lattice. In thi ca~e, the ability of the material to be shaped i~ not impaired to the extent as is the ca~e with ~tabilization on the surface.
The adhesive can impart to the moldings according to the invention, ~uch as insulating, dampinq and ~upport materials, further functions which are de~irable for the intended use under di~cu~ion for the~e moldings. Thu~, for example, impregnating propertie~ ~water-r~pell~nt character~ can be Lmparted to the moldings by additives ~5 in the adhe~ive. S~lch addi~ional properties aa~ o~ course also be generated by ~ub~equent treatm~t or by intro-duction of separate component~ into the prel~minary mixture~
A æurface desi~n is al~o pos8ible by ~praying on, for example, a dyestuff.
Such products can be employed a~ in~ulating and damping material in the building indu~itxy, and al~o in machinery constru~tion, as an i~ulati~g and soundproQfing mat~rial, if de~ired i~ combinatio~ with a .

self-supporting character or even one which can be ~ub~ected to mechanical load. A preferred field of use i8 insulation and damping in hou~e construction, where known proven combinations o~ textile propertie~ ars transferred to the building in thi6 manner. Proce~ing i~ easy, ~inee these insulating and damping ~aterials ~an be at lea~t ~elf-supporting due to the nature of theLr production.

The composition of the t~xtile materi~ based on prov~n textile mixture~ such as are ~u~tomary in the commodity and home textile ~ector. Prefexred examples of ~uch mixtures are re6idual materials o~ polye~ter/cotton 65~/35%, polyester/wool 55%/45~t acrylic/~wool mixtures or also 100~ polyester, cotton, wool, acrylic or vi~cose.
The molding~ thus ob~ainable can b~ employed, in parti-cular, as insula~ing and damping material~ and have k~own textile properties. Thi~ applie~ to, for exa~pl~, the moisture uptake, th~ dimensional stability, the temp~ra-ture properties and the like. Like the corre~ponding textile products, these insulating and damping material~
are comparably insulating and permeable to air and moisture. As with th~ corresponding textile products, thermally insulating, temperature-compen~ating and ~ou~d-damping properties are typically co~bined with one another.
The term "molding" in the context of this invention i~ to be understood as meaning sheet-like material, a8 well as products onto which a certain ~hape corresponding to later use is embossed.
Such insulating and damping material6, which are, for example, 0.5-5 cm thick, are usually flexible and ~elf-. supporting and can be cut. In a~dition, if formulated25 densely, they assume load-bearing fu~ction~, i.e. they can be loaded mechanically beyond accommodation of their own weight.
They can optio~ally be provided with a covering, for example with a decorative, surface. So that renewed recyclability i8 not limited, such a decorative sur~ace will preferably be achi~ved on the ba~is of textile products, such as, for example, by the use of non-woven~, woven fabrics, knitted fabric~ or laid fabric~
For th~ insulating ~ector~ covering with a waterproof -h ~iJ r~
~urface, permeable to vapor if required, i~ preferred, such a~ i~ cu~tomary, for example, with conventional mineral damping substance~.
The shaped article according to the invention can have ~
surface covering on either one or both ~ide~. A eurface covering on one ~ide will pxeferably ~erve to Lmpart an additional pxoperty, ~uch as modification of the decor-ation of the ~urace and/or Lmpermeability thereof ko water r while ~urface cov2ring on both ~i.dea can help to make a ~ub3tantial c~ntribution to stiffening the product.
A particular type of product ~tabilization i5 poeæible i~, or example, stabilization inside the insulating and damping material i8 effected approximately centrally by mean~ of a laid fabric or woven lattice. In thi ca~e, the ability of the material to be shaped i~ not impaired to the extent as is the ca~e with ~tabilization on the surface.
The adhesive can impart to the moldings according to the invention, ~uch as insulating, dampinq and ~upport materials, further functions which are de~irable for the intended use under di~cu~ion for the~e moldings. Thu~, for example, impregnating propertie~ ~water-r~pell~nt character~ can be Lmparted to the moldings by additives ~5 in the adhe~ive. S~lch addi~ional properties aa~ o~ course also be generated by ~ub~equent treatm~t or by intro-duction of separate component~ into the prel~minary mixture~
A æurface desi~n is al~o pos8ible by ~praying on, for example, a dyestuff.
Such products can be employed a~ in~ulating and damping material in the building indu~itxy, and al~o in machinery constru~tion, as an i~ulati~g and soundproQfing mat~rial, if de~ired i~ combinatio~ with a .

self-supporting character or even one which can be ~ub~ected to mechanical load. A preferred field of use i8 insulation and damping in hou~e construction, where known proven combinations o~ textile propertie~ ars transferred to the building in thi6 manner. Proce~ing i~ easy, ~inee these insulating and damping ~aterials ~an be at lea~t ~elf-supporting due to the nature of theLr production.
