Patent number: 6555038Abstract: The invention relates to a method for producing aqueous liquor dyeable modified polypropylene threads. The inventive method is characterized in that a CR polypropylene suitable for fiber formation is mixed with a reaction partner which can react with CR polypropylene and the mixture obtained is processed in an extrusion spinning facility to form a thread. Suitable reaction partners are difunctional carboxylic acids, corresponding carboxylic acid derivatives or master batches made of polypropylene and difunctional carboxylic acids or corresponding carboxylic acid derivatives. The polypropylene threads obtained can be knitted to form textile fabrics. The polypropylene threads and textile fabrics can be dyed with the usual coloring agents according to a standard aqueous liquor extrusion process.Type: GrantFiled: June 12, 2000Date of Patent: April 29, 2003Assignee: Deutsche Institute fur Textil - und Faserforschung StuttgartInventors: Sabine Egeler, Rainer Gutmann, Winfried Schuler, Karl-Heinrich Wiese

Patent number: 6524349Abstract: A method for maintaining the hydrophobicity of a hydrophobic polyolefin textile material over time and use. The method includes providing a solution having a pH level between 3.5 and 5.9, subjecting the hydrophobic polyolefin textile material to the solution, and drying. The processed hydrophobic polyolefin textile material maintains hydrophobicity with a contact angle with water of at least 90 degrees permanently. The processed hydrophobic polyolefin fabric can be used in a monolayer or bilayer configuration. The processed hydrophobic polyolefin fabric improves the water vapor transfer through the processed fabric because the processed hydrophobic polyolefin fabric does not saturate, wick or swell with liquid perspiration thereby reducing water liquid attached to fabric pores which increases the volume of space for diffusion of perspiration vapor from the skin, through the fabric, to the outside ambient air. The result is a drier, more comfortable processed garment.Type: GrantFiled: April 6, 2001Date of Patent: February 25, 2003Inventor: Peter C. Wittig

Patent number: 6039767Abstract: An improved method of dyeing a polyolefin material, and preferably a polypropylene based fiber, involves a disperse dye mix including a selected plurality of disperse dyes from the same primary color group. Each dye within the mix and the concentration of each dye within the mix is selected by testing individual disperse dye solutions with an undyed sample and determining the maximum dye concentration which will produce an acceptable crocking test for that dye. A plurality of disperse dyes within the mix are each at a concentration of at least 75% of the maximum dye concentration for that individual dye. The selected dye mix is used to prepare a disperse dye mix solution which is then contacted with the polyolefin material to reliably dye the material without fastness problems. A red dye mix, a blue dye mix, and the yellow dye mix may each be prepared and may each be separately used to dye polypropylene fibers with relatively dark shade without crocking problems.Type: GrantFiled: May 19, 1997Date of Patent: March 21, 2000Assignee: Equistar Chemicals, LPInventors: Geoffrey E.

Patent number: 5447539Abstract: A method of dyeing polypropylene fiber to create areas of different color on the fiber. A first dye solution containing a disperse dye and a dye-promoting agent is applied to substantially the entire surface of the fiber to cover the fiber with a first color. Thereafter, and while the fiber surface is still wet with the first dye solution, a second dye solution containing a disperse dye of a second color is applied only to selected discontinuous areas of the fiber. The second dye solution displaces the first dye solution in those areas of the fiber surface to which the second dye solution is applied. Then, the fiber is subjected to an elevated temperature high enough, and for a period of time sufficient, to fix the dyes in the fiber. Preferably, the second dye solution is more viscous than the first dye solution. After the dye fixation step, the fiber is scoured to remove excess dye. If desired, the second dye solution also contains a dye-promoting agent.Type: GrantFiled: February 10, 1994Date of Patent: September 5, 1995Assignee: DKE IncorporatedInventors: David R.

Patent number: 4378970Abstract: Red monoazo dyestuffs frm diazotised 1-aminobenzene-2-sulphonic acid-N-methyl-N-cyclohexylamide or 1-amino-4-,-5- or -6-methyl-benzene-2-sulphonic acid-N-methyl-N-cyclohexylamide and 2-amino-8-hydroxynaphthalene-6-sulphonic acid are disclosed which are particularly distinguished by their good migration and levelling properties and excellent fastness to light. Said dyestuffs are moreover suitable for obtaining very even combination dyeings together with known blue or yellow acid dyestuffs. These dyestuffs are particularly suited for the dyeing of carpeting, upholstery fabrics and drapery materials.Type: GrantFiled: October 15, 1981Date of Patent: April 5, 1983Assignee: Ciba-Geigy AGInventors: Paul Lienhard, Fabio Beffa

Patent number: 4369039Abstract: A process is provided for dyeing articles of unmodified polyolefin polymer with an aqueous dispersion of a fatty-acid-soluble, solvent dye, a fatty acid and an amine. After application of the dispersion to the article, the amine is volatilized from the applied dispersion. The process is particularly useful in providing novel, dyed, nonwoven fabrics made from polyethylene film fibrils.Type: GrantFiled: January 11, 1982Date of Patent: January 18, 1983Assignee: E. I. Du Pont de Nemours and CompanyInventor: Don M. Coates
