摘要:
Process for the continuous wet-treatment of textile material under pressure on a sieve-drum device, by leading the textile material in its open-width continuously through a rotating sievedrum device filled with the heated treatment bath and operating under atmospheric excess pressure, while the circulating liquor is pressed through the goods into the sieve-drums.
摘要:
Process for the semi-continuous dyeing of flat structures made from high-quality synthetic fibres, wherein the textile material that has been padded or printed with a dyestuff and an adjuvant is wound up on a perforated cylinder and this cylinder loaded with the goods is placed in the form of a skein into a pressure vessel, in which the pressure is greatly reduced and the padded or printed material is treated with a superheated liquid fixing medium and finished in usual manner.
摘要:
Non-aqueous process for improving a functional property of flexible, natural and synthetic, organic polymeric substrates, such as textiles, film and paper, for example, polyethylene terephthalate or cotton fabric, by applying thereto an agent other than a dye, which agent is capable of imparting the desired improved functional property to the substrate, which process comprises:1. applying said agent to the substrate from a liquid medium;2. optionally, drying the substrate to remove the liquid while substantially retaining the agent on the substrate; and3. contacting the agent-treated substrate with a fluorocarbon fluid at a temperature and for a time sufficient to effect fixation of the agent on the substrate, said fluorocarbon having an atmospheric pressure boiling point of at least 25.degree. C., a fluorine to carbon atom ratio of at least 1.5 and a solubility parameter of not greater than 7.0 and being selected from the group consisting of saturated fluorocarbons and perfluorotrialkyl and perfluorotetraalkyl ethylenes.
摘要:
Process wherein an organic disperse dye is applied, for example, to a synthetic organic polymer in the form of a film or textile fabric, for example, a polyethylene terephthalate fabric, by printing, spraying or padding and the dye-containing film or fabric is then passed through a fluorocarbon fluid at atmospheric pressure and at a temperature greater than the glass transition temperature of the polymer, said fluorocarbon having a boiling temperature of at least 125.degree.C., a fluorine to carbon atom ratio of at least 1.5 and a solubility parameter of not greater than 7.0, preferably 6.5 or less, for example, a fluorocarbon of the formula F[CF(CF.sub.3)CF.sub.2 O].sub.n CHFCF.sub.3 wherein n is at least 3.

摘要:
A method includes coating a substrate to provide a flame resistant substrate. In an embodiment, the method includes preparing a solution. The solution includes an anionic material, a cationic material, and water. The method further includes exposing the substrate to the solution to produce a coating on the substrate. The coating has cationic material and anionic material.
摘要:
A system for the fixing of prints with reactive and vat dyes in the two phase printing method on textiles made of cellulose and, in particular, continuously running webs of material made of textile, knitted material, fleece, and the like, wherein the required auxiliary means for fixing is applied onto the web of material by electrostatic spraying. The system is characterized by the provision of a device for the electrostatic spraying of the auxiliary means onto the web of material which is positioned in the fixing device.
摘要:
A PROCESS FOR THE CONTINUOUS REFINEMENT AND TREATMENT OF WIDE WEBS OF MATERIAL SUCH AS TEXTILES, WHEREIN EVERY UNIT OF LENGTH OF THE MATERIAL FLOWING THROUGH A TREATMENT BATH IS COORDINATED WITH THE QUANTITY OF PROCESSING LIQUID WHICH IS SNYCHRONOUS WITH IDENTICAL CHEMICALS IN AN INITIAL STATE THAT CAN BE EXTENDED OR REJUVENATED BY ADDITIONAL TREATMENT DURING THE EXHAUSTION OR CONSUMPTION OF THE PROCESSING LIQUID. THE PROCESSING LIQUID IS REMOVED FROM THE BATCH FOLLOWING THE EFFUX OF THE BATCH OF MATERIALS FROM THE PROCESSING APPARATUS SO THAT AS THE LAST OF THE PROCESSING FLUID IS REMOVED, A CLEANSING LIQUID IS INTRODUCED TO CLEAN THE PROCESSING APPARATUS AND REMOVE ALL TRACES OF THE PROCESSING LIQUID.
摘要:
A system and method for cationization of textiles preferably starting with the dry raw greige tubular or open width goods that are made from either a cellulosic or cellulosic blended fabric. The system can include an inducer apparatus with chemical dosification system. In a preferred embodiment, the dry tubular goods are sent in a flat configuration to a first impregnation tank where it receives a multi-functional reaction fluid. After leaving the first impregnation tank, the now wet fabric is turned (when in a tubular width fabric form) by a turning unit and then sent to a second impregnation tank where it again is exposed to the multi-functional reaction fluid. The turning of the fabric causes the side edge positions of the flat tubular fabric to change its physics dynamics which allows for the multi-functional reaction fluid to be evenly applied to the entire fabric. Turning is not needed for open with fabric as it is flat, thus having only one dynamic when analyzed with physics.
