Abstract:
An improved sieve drum device for bonding of textile material containing thermoplastic binder fibers which become tacky or melt upon the application of heat, which comprises a first sieve drum means subjected to a suction draft and rotatably mounted in a housing for heating the textile material, rolls located at the outlet of the housing for applying pressure to the textile material, and a second sieve drum means for cooling of the textile material, the first sieve drum means being operatively associated with means for providing a fresh air intake opening adjacent to the rolls.
Abstract:
A device for effecting tension-free wet treatment of textile material lengths (e.g. sheets, webs or the like continuous material) which comprises a wash bowl containing a predetermined level of processing liquor, a rotating perforated drum at least partially immersed in the processing liquor, and guide means for feeding the textile material onto the perforated drum and for removing the material from the drum. The guide means includes a beating device for forming the textile material into the wavelike plaits on the perforated drum. This device contacts the textile material above the level of liquor in the bowl, and the drum rotates at a constant speed which is lower than the speed at which the textile material is fed into the bowl onto the drum.
Abstract:
A godet for transporting and heating fibers comprises an outer and an inner cylindrical shell which define an annular space therebetween for the flow of a fluid heating medium, an end wall secured to the outer shell, and a bearing shaft attached to the end wall via radial and axial fitting surfaces. A continuous layer of heat-insulating material is provided for the radial and axial fitting surfaces. Also, a godet construction having means to collect and return leakage oil from the outside of a bearing housing to the inside of the housing is disclosed.
Abstract:
THE PRESENT DISCLOSURE IS DIRECTED TO A PROCESS AND APPARATUS FOR THE WET-TREATING, FULLING AND/OR KNEADING OF TEXTILE MATERIAL LENGTHS WHICH COMPRISES AT LEAST ONE LIQUOR CONTAINER ADAPTED TO CONTAIN A TREATMENT LIQUOR, SAID LIQUOR CONTAINER CONTAINING A SIEVE DRUM MEANS, ROTATABLY DISPOSED THEREIN, DRIVE MEANS FOR ROTATING SAID SIEVE DRUM MEANS, A LIQUID-PERMEABLE TROUGH MEANS PROVIDED IN THE LIQUOR CONTAINER AND EXTENDING A DISTANCE FROM THE SURFACE OF THE SIEVE DRUM MEANS, SAID TROUGH MEANS AND THE SURFACE OF SAID SIEVE DRUM MEANS DEFINING A COMPRESSION CHANNEL THEREBETWEEN, INLET MEANS FOR OVERFEEDING THE MATERIAL TO BE TREATED TO THE COMPRESSION CHANNEL THEREBY PLAITING THE MATERIAL AT THE BEGINNING OF SAID CHANNEL, MEANS FOR SUPPORTING AND DRIVING THE SIEVE DRUM MEANS SO THAT IT PERFORMS AN OSCILLATING MOTION DURING ROTATION, THEREBY SUBJECTING THE PLAITED MATERIAL LENGTH IN THE COMPRESSION CHANNEL TO A MECHANICAL TREATMENT DUE TO THE VARYING COMPRESSION FORCE OF THE SIEVE DRUM MEANS AGAINST THE PLAITED MATERIAL IN SAID COMPRESSION CHANNEL, AND OUTLET MEANS FOR REMOVING THE PLAIT-LIKE OVERFEED AT THE OUTLET OF THE COMPRESSION CHANNEL. THE PRESENT DISCLOSURE IS ALSO DIRECTED TO THE COBINATION OF THE WET-TREATMENT PROCESS AND APPARATUS WITH AN ACIDIFYING, A CARBONIZING, PADDING, AND A DRYING PROCESS AND APPARATUS. D R A W I N G
Abstract:
The present disclosure is directed to a process and apparatus for the heat-treatment of textile materials wherein the material to be treated, for example thick material layers, can be heated shock-like to the treatment temperature and subsequently heated very uniformly. According to the present disclosure the treatment medium, for example steam, is evenly distributed throughout the treatment chamber.
Abstract:
The present disclosure is directed to an apparatus for the treatment of endless textile material lengths which comprises a container means adapted to contain a treatment liquor and composed of a conveying zone and a dwell zone, partition means dividing the dwell zone into two channels and a perforated drum means subjected to a suction draft rotatably disposed in the conveying zone in such a manner that it is adapted to receive the textile material from one of the channels and introduce it into the other of said channels.
Abstract:
The present disclosure relates to a process and apparatus for bonding felts or feltlike materials which comprises adding to the materials to be bonded a synthetic bonding fiber thereby forming a fiber blend and fuse-bonding the fiber blend by heat-treating said blend to the sticking or melting point of the bonding fibers and setting the fiber blend by cooling down the bonded fibers, said heat-treatment and cooling down stages being effected shocklike by passing at least part of the heating and cooling treatment medium through the material being treated. The present disclosure is particularly directed to the use of steam during the treatment process as well as to the application of pressure to the fiber blend while said blend is in a heated state.
Abstract:
THE PRESENT DISCLOSURE IS DIRECTED TO A CONTINUOUS PROCESS FOR PAD DYRING, PRINTING OR BLEACHING TEXTILE MATERIALS WHICH COMPRISES IMPREGNATING THE MATERIAL TO BE TREATED WITH THE TREATMENT LIQUOR, AND RAPIDLY AND UNIFORMLY HEATING-UP AND SETTING THE MATERIAL IN A TREATMENT CHAMBER WITH A GASEOUS OR VAPOROUS TREATMENT MEDIUM, SAID TREATMENT MENDIUM PENETRATING THE TEXTILE MATERIAL IN AN UPWARD DIRECTION SO THAT THE TEXTILE MATERIAL AT LEAST PARTIALLY RESTS ON A STEAM OR GAS CUSHION HEREBY ENSURING PROPER MATERIAL SHRINKAGE. THE PRESENT DISCLOSURE IS ALSO DIRECTED TO AN APPARATUS FOR PERFORMING THE ABOVE PROCESS.
Abstract:
A PROCESS FOR FINISHING, ESPECIALLY BLEACHING AND/OR DESIZING KNITTED FABRICS AND HOSIERY GOODS, SUCH AS FOR EXAMPLE CELLULOSE FIBERS, WHEREIN THE KNITTED FABRICS AND HOSIERY GOODS ARE IMPREGNATED WITH THE TREATMENT LIQUOR, STEAMED, WASHED AND/OR RINSED AND DRIED. THE KNITTED FABRICS AND THE HOSIERY GOODS ARE CONTINUOUSLY TRANSPORTED AND GUIDED IN OPEN WIDTH AND WITHOUT ANY SUBSTANTIAL TENSION DURING THE INDIVIDUAL TREATMENT PROCESSES.
