The above potential crimping composite fiber exhibits crimping at a reduced temperature and also has thermal adhesiveness.
A space between the scrapers defines a crimping chamber.
These composite fibers are in an actualized crimped state in which three-dimensional crimping has been developed, or are potentially crimpy, i.e., they develop three-dimensional crimping upon heating.
In general, the fibers are produced by crimping a polymeric fiber and then cross-linking a polymer and/or monomer contained within the fiber.
The instant invention is a stuffer box crimper and a method for crimping.
The aim of the invention is to obtain a good creping effect and at the same time reducing the wear of the crepe band.
A creping adhesive may be deposited on the creping surface according to a predetermined pattern.
The closed pocket creping normally produces a thicker, less dense tissue but with coarse crepe.
The aim of the invention is to obtain a good creping effect and at the same time reducing the wear of the crepe band.
Creping adhesives, and methods for making and using them in the creping of cellulosic fiber webs.
For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation.
In accordance with the present disclosure, the additive composition is applied to a creping surface.
For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation.
For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation.
For instance, in one embodiment, the additive composition may be applied to the sheet as a creping adhesive during a creping operation.
In accordance with the present invention, the multicomponent filaments contain a crimp enhancement additive.
A process for dry creping tissue paper comprising the application of creping adhesives in at least two steps.
The elevations press the tissue sheet against the creping surface.
Cross-linking the polymer makes the crimp contained with the fiber more permanent and more resilient.
The blade according to the invention has a ceramic top layer covering the working edge of the blade, as well as the surface upon which the web impacts during creping.
Methods of creping using the oil-based formulation are also described.
After creping, the web is dried, preferably with a plurality of can dryers to a consistency of at least about 90 percent while it is held in the creping fabric.
That exciting catfight between between Ronda Roussey and Michelle Rodriguez promises to be awesome on the big screen!
The creping allows the coffee to flow freely between the filter and the filtration funnel.
The invention also relates to the use of the adhesives (i) to (iii) as auxiliary agents in the crêping process.
The ratio (crimp rate (%)/number of crimps (count)) between the crimp rate (%) measured in accordance with JIS L1015 and the number of crimps (count) measured in accordance with JIS L1015 is preferably between 0.45 and 0.75.
The creping knife has a ceramic tip (100) that engages the roller and induces a creping pattern into the kraft paper as the paper is creped from the roller.
These compounds are useful as tackifying resins for creping adhesives.
The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the throughdrying fabric when the dried sheet is applied to the surface of the creping cylinder.
The products are most preferably prepared by way of a compactive dewatering/wet crepe process.
