摘要:
A feather processing machine comprising a cleaning drum, means for introducing soiled feathers into the drum, means for agitating the feathers within the drum and blower means outside of the drum in communication therewith for withdrawing feathers from the drum and discharging them from the machine.
摘要:
A molded hat having improved shape retention and recoverability properties wherein the fabric of the crown and brim comprises a single unit eliminating the need for sewing the brim to the crown, said fabric containing a stabilizing polymeric composition. These molded hats are prepared by placing the stabilized fabric in a hat mold and thereafter applying heat and pressure to effect the desired shape. The improved shape retention and recoverability properties result from the presence of the polymeric composition in the fabric.
摘要:
A process for the modification of monomerpretreated-keratinous substrates which comprises treating the keratinous substrate with a small but effective amount of a compound comprising a mercury salt of an organic carboxylic acid.
摘要:
A METHOD OF IMPROVING THE QUALITY AND "HOLD" OF A "SET" IMPARTED TO THE HAIR, WHICH METHOD COMPRISES THE STEPS OF APPLYING A REDUCING AGENT TO SAID HAIR WHILE IT IS MOIST AND UNCONSTRAINED, AND THEN NEUTRALIZING IT, SAID STEPS BEING CARRIED OUT BEFORE THE HAIR IS "SET".
摘要:
The present invention generally relates to a textile softening composition which comprises, as the softening agent, a quaternary ammonium salt which comprises a mixture of mono-, di-, and tri-ester components, wherein the amount of diester quaternary is greater than about 55% by weight, and the amount of triester quaternary is less than about 25% by weight based on the total amount of quaternary ammonium salt. The invention also relates to a process for preparing said softening agent.
摘要:
A process for protecting keratinous material with the aid of substantially novel pyridyloxytrifluoromethanesulfonanilides from pests that feed on keratin, said pyridyloxytrifluoromethanesulfonanilides having the formula ##STR1## wherein R.sub.1 and R.sub.2, each independently of the other, are halogen, haloalkyl, alkyl, nitro, cyano, alkoxy or haloalkoxy or alkoxycarbonyl, andn and m, each independently of the other, are 0 or a value from 1 to 3, with the proviso that if n or m>1, the substituents R.sub.1 and R.sub.2 may be identical or different, and that at least one substituent selected from the group consisting of halogen, haloalkyl and haloalkoxy is present in the molecule.The preparation of these compounds and the use thereof as active ingredients of compositions providing a mothproof and beetle-resistant finish are also described herein.
摘要:
AN ACRYLIC FIBER ARTICLE IS IMPROVED BY TREATING IT WITH A SOLUTION OF A SOLVENT HAVING A CONCENTRATION HIGHER THAN THAT AT WHICH THE SOLUTION BEGINS TO DISSOLVE THE FIBER AND LOWER THAN THAT AT WHICH THE SWELLING VELOCITY OF THE SOLUTION ON THE FIBER SURFACE IS EQUAL TO THE DISPERSING VELOCITY OF THE SURFACE OF THE SWELLED LAYER TO PEEL THE FIBER. EXAMPLES OF SUCH SOLVENT ARE DIMETHYLFORMAMIDE, DIMETHYLACETAMIDE, DIMETHYLSULFOXIDE, SODIUM THIOCYANATE, ZINC CHLORIDE, SULFURIC ACID, NITRIC ACID, ETC.
摘要:
Durable-press fabrics which are very active to recuring reactions are produced by depositing activating catalysts in durable-press fabrics which have carboxylic acid groups covalently bonded to the cellulose of the fibers. Sharp, permanent creases can be formed in these activated fabrics without severe strength losses by pressing and heating them under mild conditions of time and temperature.
