摘要:
A method for continuous liquid treatment of a cloth comprising transporting a cloth soaked with a treating solution continuously under width expansion by the use of a tenter while subjecting the cloth successively to wet heat treatment by jetting high temperature hot water thereto and drying the resultant cloth by jetting hot blast thereto. Under certain circumstances, it is preferably to swell the cloth by applying high temperature hot water thereto after the cloth is soaked with the treating solution for expanding width of the cloth and/or to dry the cloth tentatively before the wet heat treatment thereof for preventing the peeling off of the treating agent applied to the cloth.

摘要:
A process for expanding or puffing fibrous or plastic materials such as paper, tobacco, cotton, asbestos, plastic films, etc., whereby the expandable material in sheet or filament form and a puffing agent are continuously advanced under pressure through a pressure zone defined between a pair of opposed surfaces which continuously separate at the zone outlet so that as the expandable material and puffing agent pass out of the pressure zone the agent expands and puffs the material. Heat is usually applied to the pressure zone to generate or increase the pressure therein. The puffing may be in the form of a liquid, such as water or fluorinated hydrocarbons, or a gas, such as steam. The puffing agent may be supplied separately to the pressure zone or concurrently with the expandable material.
摘要:
Cellulosic textile materials are reacted with ethylenically unsaturated compounds which, in polymer or copolymer form, have a glass transition temperature in excess of 50* C. to produce a material which may be set under heating conditions in a desired configuration which is durable to the effects of wetting with water.
摘要:
Granular detergent compositions with through-the-wash fabric softening properties are prepared from conventional detergent ingredients, clay fabric softeners, and microfine particles of a complex of long-chain amine and fatty acid. The amine fatty acid complex provides fabric softening performance in the compositions when fabrics washed therein are dried. Importantly, the drying operation can be simple line-drying and machine drying is not required to secure the benefits of the invention, although machine drying may be used, if desired.
摘要:
The disclosure is directed to a system for the recovery of spent ammonia, in connection with the processing of fabrics and the like with liquid ammonia, and concerns particularly the elimination from the recovered ammonia of undesired water.Economic processing of fabrics by liquid ammonia requires recovery and reuse of substantial quantities of ammonia. In the course of processing, the ammonia unavoidably becomes contaminated with water. Separation of water from ammonia on a laboratory level or, in any kind of batch processing is a theoretically simple matter and can be coped with by conventional differential evaporation techniques, or otherwise. However, in a continuously operating processing line where large quantities of anhydrous liquid ammonia are being used as the treating medium, water accumulates rapidly, not only from the fabric being processed, but also from a certain inevitable amount of air leakage in the system. Because so much of any given increment of the treating medium must be recycled, as compared to that actually "used up" in the treating process, water accumulates rapidly in the system and must be removed on a continuous basis. The specification discloses a unique and highly efficient procedure for removal of water by effecting condensation of water and ammonia vapors, constituting the process effluent, by feeding the effluent to a desuperheating vessel, where it is brought into direct contact with a body of low temperature liquid ammonia. This is done in conjunction with a preliminary low temperature condensation of the effluent in a non-contact heat exchange stage. The condensed body of liquid ammonia in the desuperheater vessel, including residual condensed water from the process effluent combined with re-liquefied ammonia, forms the feed supply of liquid ammonia solution to the process. The condensed water, which in the new process constitutes a portion of the feed supply, is applied to the fabric being treated, along with the liquid ammonia. Typically, some of the water is carried away with the processed fabric as a constituent of its moisture content. The remainder, which is driven off as steam in the process, is recycled.A key factor in the new process is that the re-liquefied ammonia, instead of being sent directly back to the process, is directed into the desuperheater vessel, there being combined with the condensed process effluent. The combined solution, containing a minor fraction of condensed residual water is then fed back to the process. In this manner, the total water fraction in the process solution may be kept a satisfactorily low level, typically on the order of two or three percent maximum, under extreme process conditions, and desirably much lower than that under more favorable process conditions.
