An applicator for temporarily masking stains on clothing includes a canister having an chamber for containing fluid, a water based, stain masking solution disposed within the chamber of the canister, and a brush or a spray head applying the stain masking solution from the chamber of the canister on a stain requiring masking. The stain masking solution covers the stain so that the stain is substantially concealed. The canister has an elongate annular wall having an open end at one end thereof, and an end wall closing the other end of the annular wall. Preferably, the stain masking solution consists of: resin--approximately 10.0 percent by weight; isopropanol--approximately 15.0 percent by weight; water--approximately 55.0 percent by weight; titanium dioxide--approximately 15.0 percent by weight; and ammonia--approximately 5.0 percent by weight.

A method for modifying wool fiber materials to advance quality grade thereof, wherein a wool fiber material is dipped in a saturated solution of a neutral salt of a strong electrolyte and an acid, whereby the acid is included in the edge portions of the endo cuticles of the scales of the wool fiber, and then the wool fiber is dipped in a saturated aqueous solution of the neutral salt having a pH in the neutral range or in water to effect gradual chlorination of the wool fibers, wherein the aqueous solution or the water contains a compound such as sodium hypochlorite, sodium chlorite, chlorocyanuric acid salt and mixtures thereof. The wool fiber is then removed from the saturated aqueous solution, dipped in water to swell the chlorinated portions thereof and washed with water to remove the chlorinated portions. Finally, the thus treated wool is contacted with a solution containing sodium pyrosulfite and an alkaline liquid to provide wool fibers having a smooth surface.

A process for treating textile materials such as yarns, fabrics or the like is taught. The specific improvement lies in impregnating the textile material with ammonia and applying to the impregnated material stresses of about 25% to 30% of the breaking load of that material for ten or more seconds; thereafter removing a first portion of ammonia to reduce the degree of impregnation to less than 75% by weight after less than 3 seconds while stresses are reduced to about 15% of the breaking load of the material; removing a second portion of the ammonia such that the degree of impregnation is less than 30% by weight after less than 60 seconds, while stresses remain approximately the same as those in the preceding step; and finally removing the balance of the impregnated ammonia while maintaining the stresses below 5% of the breaking load of the textile material, the ammonia being removed at such a rate that the degree of impregnation is less than 15% by weight after less than 300 seconds. All of the time intervals for ammonia removal are measured from the start of ammonia removal.

The disclosure relates to equipment and techniques for the removal from fabrics of excess residual ammonia, remaining in the fabric after liquid ammonia processing. The process involves contacting the opposed surfaces of the fabric with a thin film of water, followed by removal of the water from the fabric. The amount of water which contacts the fabric is insufficient to wet the fabric, so that it does not require a subsequent drying step, but is sufficient to release most of the residual ammonia, causing the ammonia to be extracted from the fabric. To advantage, the thin film of water is achieved by condensation of steam on chilled rollers.

This disclosure teaches a method and a related apparatus for pretreating cellulosic fabrics with liquid ammonia to improve their comfort characteristics as well as their resistances to shrinking and wrinkling and to enhance their affinities for dyes, flame retardants, resins and the like and generally to condition the fabrics better for subsequent finishing operations. A fabric is impregnated with liquid ammonia and is subjected quickly (from about 0.6 to about 9.0 seconds and preferably from about 1.8 to about 3.6 seconds) to removal of the ammonia by drying the fabric so as to achieve these desired results without effecting substantial shrinking of the fabric. The time interval between the impregnation with and the removal of the ammonia from the fabric is controlled preferably by regulating speed of advance of the fabric and by regulating length of path of the fabric from the impregnation with the liquid ammonia to commencement of the removal.

Disclosed is a knitted fabric containing natural fibers and a making method therefor, a liquid ammonia device and a shirt made from the knitted fabric, belonging to the fields of fabrics and clothing. The making method for the knitted fabric containing natural fibers comprises forming yarns containing natural fibers into a knitted fabric by a fabric-knitting method; and performing functional finishing including a liquid ammonia finishing procedure on the knitted fabric. In the liquid ammonia finishing procedure, liquid ammonia impregnation is performed on the knitted fabric at least twice under the condition of mechanical restraint by a guide roller set, thus preventing the knitted fabric from edge curling due to strong shrinkage in the liquid ammonia impregnation process, enabling the knitted fabric to be subjected to sufficient and uniform liquid ammonia impregnation, ensuring the liquid ammonia impregnation effect and controlling the shrinkage rate of the knitted fabric; and through subsequent shaping and finishing procedures, the color stability of the knitted fabric is further improved, the shrinkage rate after washing is reduced, and the crease-resistant performance and resilience performance are improved. The shirt has a low shrinkage rate after washing, good stiffness performance, good resilience performance, color stability, high strength and good crease-resistant performance.
