摘要:
A formulation for finishing a cellulosic substrate, or a blend thereof, in a finish bath, the formulation comprising from about 3.0% to about 60.0% by weight of non-formaldehyde dimethylurea/glyoxal (DMUG), or an analog thereof, and from about 0.1% to about 4.0% by weight of one or more additives selected from dicyandiamide, choline chloride, ethyleneurea, propyleneurea, urea, dimethylurea, and combinations thereof, wherein the percent by weight is given in terms of percent weight of the finish bath, and wherein the formulation is substantially free of dimethyloldihydroxyethyleneurea (DMDHEU), and methods of use thereof.
摘要:
A system is disclosed wherein fibers are mounted on pallets for ease in handling and storage. The system uses the pallets to provide a continuous, uniform rate of fiber feed to other apparatus for subsequent fiber processing. A positioning system arranges pallets in end-to-end abutting relationship to provide the uniform rate of fiber feed generally desired for fiber processing. A plurality of vertically spaced horizontally disposed rotating augers engage the advancing face of fibers on a pallet to remove the bulk of fibers therefrom. The pallet surface is subsequently engaged by a pallet sweeper which removes any fibers not removed by the rotating augers. The loosened fibers are deposited on a transverse conveyor which overlies the pallet surface and moves the fibers transversely of the pallet unloading apparatus for delivery to the fiber processing apparatus.
摘要:
Cellulosic materials such as cotton fabrics or garments are made crease resistant by exposing them to formaldehyde vapor at an elevated temperature after pre-impregnation of fabric with a formaldehyde-free aqueous solution of a latent catalyst, preferably zinc chloride.
摘要:
A tufted carpet primary backing made up of a nonwoven base web formed from low cost short fine fibers (e.g. cotton) and longer coarse fibers (e.g. 4 inch, 15 denier synthetic fibers) bonded together. The nonwoven is needled and reinforced by the addition of other strength imparting components, such as threads or continuous filaments stitched on the web in a tricot pattern.
摘要:
A seed cotton stacking apparatus with a mechanical compressor means pivotally attached adjacent the rear end of a slip form. The open top - open bottom slip form has upwardly extending side walls and a front end wall which define a cotton receiving zone. The side walls include outwardly flared, upper portions. The compressor means includes a crop contacting platen which has a generally planar central portion and downwardly sloping edge portions. The slip form is supported on longitudinally extending skids which are in ground contact during the rick forming process. A selectively operable wheel assembly is included to pivot a pair of wheels downwardly thereby lifting the slip form to a transport position from a skid position.
摘要:
A durable press garment is made by cutting and assembling the garment from a cellulose fiber-containing fabric, pressing the garment to impart a suitable crease thereto, applying a liquid impregnant containing all constituents for giving the garment durable press characteristics upon subsequent heating, said application of liquid impregnant being performed without significantly disturbing the pressed condition of the garment, then drying the impregnated garment under normal atmospheric conditions, re-pressing the garment without curing the impregnant to eliminate any wrinkles which may have formed therein and to touch up the crease, and heating of the garment at about 200* 350*F. to cure the creaseproofing agent.

MONOHYDRIC ALIPHATIC ALCOHOLS CONTAINING FROM 4 TO 12 CARBON ATOMS ARE EFFECTIVE IN THE CONTROL OF MICROORGANISMS WHICH CAUSES DISEASES OF PLANTS SUCH AS COTTON OR WHICH PRODUCE TOXINS THAT IMPAIR THE USEFULNESS OF PRODUCTS OF PLANTS INTENDED FOR HUMAN OR ANIMAL COMSUMPTION SUCH AS COTTONSEED OIL OR MEAL.
摘要:
A liquid atomizing method and apparatus including a conduit member having an annular ring eccentrically mounted thereon such that a radial port in the ring is aligned with a radial aperture in the conduit member. A thin flexible orifice ribbon is intercalated between the ring and the conduit member. In one embodiment of the invention, a vibratory device is rigidly mounted upon the exterior surface of the conduit member and functions to induce the formation of uniform droplets within fluid flowing through apertures in the orifice ribbon. In another embodiment of the invention an elongate flexible orifice ribbon, having a plurality of spaced orifice zones, may be mounted upon an advancement mechanism to facilitate maintenance of a clean unobstructed set of apertures in communication with the conduit port. The atomizing apparatus is readily serviceable without special tools.
摘要:
An apparatus for the continuous treatment of an advancing web such as a cotton fabric with one or more reactive gases comprises one or more reaction chambers, each including fluid discharge means for directing a treating gas onto the web in the chamber and evacuation means disposed on both ends of the chamber to prevent both the fluid from escaping from the chamber and the fluid outside the chamber from entering the chamber. Heating means adapted to heat the continuously advancing web of fabric material may also be provided. Suitable heating means include a plurality of heated rotary drums. Such an apparatus may be used for the application of gases such as formaldehyde or sulfur dioxide or both to a cellulose fibercontaining fabric at an elevated temperature and in the presence of controlled amounts of moisture. In this manner, a previously applied N-methylol precondensate can be ''''wet fixed'''' in the fabric, thus making it possible to improve the wrinkle resistance and other shape-holding properties of the fabric while preserving good fabric strength after an eventual dry cure. Such a process can also be used directly to impart the desired shape-holding properties to the fabric, e.g., by crosslinking cotton by means of an acid-catalyzed formaldehyde reaction in the described apparatus.
摘要:
Cotton fiber assemblies, such as cotton toweling and diapers, are produced with increased absorbency by fixing cotton fibers in their never-dried botanical growth state and forming the assemblies from the fixed fibers. The never-dried cotton fibers can be fixed with blocking agents such as formaldehyde and acrylamide.
