A treatment agent for elastic polyurethane fibers comprising a dispersion in which a higher fatty acid magnesium salt is colloidally dispersed in a silicone mixture consisting of a silicone oil with a viscosity of 5&times;10 &minus;50&times;10 m /S at 25&deg; C. as a dispersion medium and a dispersant mainly comprising a modified silicone at a ratio by weight of the dispersion medium/the dispersant&equals;100/0.5-100/4.5, wherein the amount of the higher fatty acid magnesium salt is 1 to 10 parts by weight per 100 parts by weight of the silicone oil.

Treatment agent for elastic polyurethane fibers and elastic polyurethane fibers treated therewith

The present invention is directed to a stretchable adhesive nonwoven prepared by laminating continuous filaments made of a thermoplastic polyurethane resin, which comprises an aliphatic diisocyanate and/or an aromatic diisocyanate, a polymeric diol and a chain-extending agent and has a hardness (JIS-A hardness) of 65 to 98 degree and a flow initiating temperature within a range from 80 to 150&deg; C., into a sheet, and fusion-bonding the filaments themselves with their own heat at the contact point of the laminated filaments thereby to form fibers, and a laminate containing the same. The adhesive nonwoven fabric of the present invention is rich in flexibility and is excellent in adhesion and air permeability.

Antibacterial zeolite causing little discoloration and method of the

A heat resistant colorant for mass-coloring polyester such as polyethylene terephthalate, containing 100 parts of pigments and/or dyes and 42.about.2,000 parts of a liquid aliphatic polyester dispersing medium having a viscosity at 25.degree. C. not exceeding 150 poises and a hydroxyl value not exceeding 25 mgKOH/g. The dispersing medium contains a polycondensate of alkylene glycols including at least 30% by weight of 1,3-butanediol with at least one aliphatic dicarboxylic acid, which polycondensate has at least one terminal group blocked with a monohydric alcohol. The colorants are easily blended and uniformly dispersed in a fiber grade polyester, without causing degradation of the polyester. Fibers mass-colored by the colorant are excellent in stability during their manufacture and uniform in quality.

Colorants, polyester fibers mass-colored therewith and process for

A black liquid colorant for dope dyeing of polyester fibers, comprising 5-50 wt % carbon black obtained by wet-oxidation with peroxide and subsequent neutralization of a gas phase oxidized carbon black, and 95-50 wt % liquid dispersion medium such as liquid polyester. Black polyester fibers, typically polyethylene terephthalate fibers, dope-dyed with preferably 3-15 wt % base on the polyester of said black liquid colorant, have a deep blackness with a bluish tone and neither polymer deterioration nor filament breakage is observed.

Black liquid colorant and polyester fibers dope-dyed therewith
