Abstract:
This invention relates to a manufacturing process of synthetic yarn and the produced yarn which has superior texture and brightness, and excellent color developing, hygroscopicity, and anti-static properties. A plurality of monofilaments is drawn out at an appropriate speed, dried and heated. Then a property enhancing agent containing a metallic salt, alcohol, optional solvent and optional additional functional agent, such as a hygroscopic agent, ultraviolet protecting agent, or resist agent, etc. is applied onto the surface of the filaments which are melted and flame bonded to each other. Multi-filaments are formed with spaces therebetween in which the functional agent remains inserted. The new synthetic yarn is produced after the multi-filaments are subjected to washing, drying and take-up procedures.
Abstract:
This invention relates to an improved process for providing fibrous polyamide materials and wool materials with stain resistance and superior lightfastness that are more durable against alkaline washing. This is accomplished by treating the materials with an aqueous solution comprising a combination of a partially sulfonated novolak resin, methacrylic polymer and a soluble aluminum compound or a combination of a partially sulfonated novolak resin and a soluble aluminum compound.
Abstract:
A composition and process for formulating a size and for sizing and desizing textiles using an inorganic compound are provided. One inorganic compound that may be used is basic aluminum chloride. The use of basic aluminum chloride in a size formulation creates a size that is less environmentally hazardous but effective as a size.
Abstract:
The invention concerns a security-marking procedure, an apparatus to sense a security marking, fiduciary documents provided with security markings, by resorting to rare-earth chelates consisting of at least two rare-earths and of which the fluorescence wavelengths vary as functions of temperature, and fiduciary document containing such chelate(s).
Abstract:
This specification discloses a flame retardant vegetable fiber material and the process for the production of the same. The adopted means is to immerse the vegetable fiber into a firstly prepared inorganic solution and also into a secondary prepared inorganic solution in turn, while both solutions come into the inherent gaps of the said fiber and become an insoluable and incombustible inorganic compound therewith. The mutual contact and reaction caused by the first and second solutions generate a setting dip and fixation thereupon.

Abstract:
An inorganic binder composition is employed in combination with fillers comprising particulates, fibers, filaments or yarn to form a structure. The coating is prepared from colloidal silica, monoaluminum phosphate, aluminum chlorohydrate an organo tin catalyst and optionally a refractory material.
Abstract:
An aqueous fabric softening composition containing less than 10% cationic softener also includes an alkoxylated fatty amine having up to 7 alkylene oxide groups per molecule, such as ethoxylated tallow amine at exemplified levels of 4.0 to 12.0%. The alkoxylated compound enhances the softening and anti-static properties of the composition.
Abstract:
Flame retardant, shaped materials comprising a vinyl polymer of crosslinked structure containing in its vinyl units 40 mole-% or more based on the polymer of COOH groups which have been partly converted to COOM (M: a mono- to tri-valent metal) groups, the COOM group content of said polymer being preferably 0.5 to 40 % by weight in terms of metal content.
Abstract:
Bonded fibrous nonwoven textile fabrics having excellent strength and textile-like softness, drape and hand which are intermittently bonded with synthetic resins in predetermined print patterns of binder areas having a relatively high, uniform concentration of from about 50 to about 120 percent by weight of resin binder in the binder areas, based on the weight of the fibers therein, said binder areas having very sharply defined borders or edges with a minimum of binder feathering thereat whereby the optical density of the bonded fibrous nonwoven textile fabric very sharply increases from substantially zero to a maximum of at least from about 0.6 to about 1.0 or greater in a distance of less than about 1 mm. (0.04 inch), and methods of depositing such synthetic resins from colloidal aqueous dispersions thereof onto wet fibrous webs to form the bonded fibrous nonwoven textile fabrics, comprising the use of (1) metal complex coordination compounds and (2) synthetic resins and/or surfactants, at least one of which contains a specific coordinating ligand capable of being affected by ions of said metals to control the total migration of the resin binder during such deposition.
