  • Patent number: 6168635
    Abstract: A dyeing system composition for use in printing articles formed from cellulose prior to dyeing. The dyeing system composition includes the use of both a dye blocking print paste and a dye enhancing print paste to selectively decrease or increase the shade of dyed portions of a cellulose article such as a woven cotton fabric.
    Type: Grant
    Filed: November 12, 1999
    Date of Patent: January 2, 2001
    Assignee: Burlington Chemical Co., Inc.

  • Patent number: 5820638
    Abstract: A composition for the elimination of cellulosic dye cross staining when dyeing cellulosic and synthetic blended fabrics in a dye bath. The composition includes a first component including polyvinylpyrrolidone polymer having a mwt. of between about 15,000 to 40,000 and the balance water. In the preferred embodiment, the composition includes a second component including dyestuff including dyes and polyvinylpyrrolidone polymer. Dyeing textile articles having at least two different types of fibers selected from the group consisting of cellulosic and synthetic fibers using the present invention produce a dyed article in which the cellulosic fibers are dyed and the synthetic fibers have a Class Value of greater than about 3 when measured according to the AATCC Gray Scale for Color Change.

  • Patent number: 5772697
    Abstract: Liquid caustic compositions for use in reactive dyeing, having total and alkaline activities approximating the total and alkaline activities of a predetermined liquid caustic composition are prepared by providing a source of water; providing a container of concentrated sodium hydroxide solution; providing a container of liquid buffered alkali solution; providing a mixer communicating with the containers; providing at least one liquid caustic solution storage tank in communication with the mixer; providing flow meters communicating with the mixer to monitor the quantities of sodium hydroxide and buffered alkali flowing to the mixer; determining the total and active alkalinities of the target liquid caustic composition; determining the quantities of sodium hydroxide and buffered alkali solutions required to provide a liquid caustic solution having total and active alkalinities approximating the total and active alkalinities of the target solution; diluting the concentrated sodium hydroxide with the water to for

  • Patent number: 5616280
    Abstract: A bleaching composition for cellulosic materials such as paper pulp, cotton and cotton blends. The chemical system of the present invention includes a mixture of sodium hydroxide, optical brighteners and an enhanced hydrogen peroxide composition including a silicate-free stabilizer. In the preferred embodiment, the silicate-free stabilizer includes a magnesium salt; an aminoalkylphosphonic acid; dipicolinic acid; and the balance water. The resulting textile goods are soft, absorbent, silicate-free with a Hunter Scale whiteness of greater than about 85. Because a silicate-free stabilizer is used, low levels of extractable solids are obtained.

  • Patent number: 5464563
    Abstract: A bleaching composition for cellulosic materials such as paper pulp, cotton and cotton blends. The chemical system of the present invention includes a mixture of sodium hydroxide, optical brighteners and an enhanced hydrogen peroxide including a silicate-free stabilizer. In the preferred embodiment, the silicate-free stabilizer includes; magnesium acetate; phosphonic acid derivative or substituted phosphonic acids; dipicolinic acid; and the balance water. The resulting textile goods are soft, absorbent, silicate-free with a Hunter Scale whiteness of greater than about 85. Because a silicate-free stabilizer is used, low levels of extractable solids are obtained.
