  • Patent number: 8911508
    Abstract: The present invention discloses a modifier for modifying a polyester fiber as well as a preparation method and application of the same. The modifier contains ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, two-polyether-end modified organosilicon and a metal acetate catalyst. A two-step continuous production process is adopted. The first step is esterification; that is, ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, and two-polyether-end organosilicon are added into a reactor, and have an esterification reaction in the presence of the catalyst. In the second step, the materials produced by the esterification are transported to a polymerizer, and have a polymerization reaction under the conditions of high temperature, vacuum and catalyst, producing the high molecular weight polyester/polyether/organosilicon terpolymer with a molecular weight of 1000˜50000 as the desired modifier.

  • Patent number: 5972049
    Abstract: Improvements in the disperse dyeing process for hydrophobic textiles by the use of novel dye carrier formulations are disclosed. The carrier composition for use in disperse dyeing of hydrophobic textile material preferably comprises an alkylphthalimide carrier component and a clay dispersing agent. Dye baths and methods of disperse dyeing of a hydrophobic textile material are also disclosed. The use of clay as a dispersing agent allows for the use of carrier compositions with reduced health and environmental hazards without adversely affecting dyeing characteristics.

  • Patent number: 5490866
    Abstract: A process is disclosed for washing-off prints or dyeings produced with dyes on cellulosic textile materials, which comprises treating the printed or dyed fabrics in an aqueous wash liquor with a washing-off formulation comprising(a) a polyvinyl pyrrolidone homopolymer or copolymer, and(b) a water softener.The inventive process makes it possible to remove unfixed dye from the fibre material completely and thus to enhance the fastness properties of the dyeings.

  • Patent number: 5378242
    Abstract: A liquid alkali for use in soaping off of cotton and cotton blended fabrics. The liquid alkali is a water-based solution of an alkali metal hydroxide and an alkali metal silicate. Preferably the composition is an aqueous mixture of potassium hydroxide and sodium silicate. In the most preferred embodiment the composition includes 35 wt % potassium hydroxide at a 45 wt % concentration, 25 wt % sodium silicate at 50.degree. Baume, and the balance water. In an alternative embodiment, up to 5 wt % of a borate is added.

  • Patent number: 5372611
    Abstract: A liquid alkali composition for use in fiber reactive dyeing of cotton and cotton blended fabrics or the like. The liquid alkali is a water-based solution of an alkali metal hydroxide and an alkali metal silicate. Preferably the composition is an aqueous mixture of potassium hydroxide and sodium silicate. In the most preferred embodiment the composition includes 35 wt % potassium hydroxide at a 45 wt % concentration, 25 wt % sodium silicate at 50.degree. Baume, 5 wt % of a borate, and the balance water. The resulting solution has a high enough pH to achieve reaction between the dye and fiber but is sufficiently buffered to achieve this reaction slowly so that the fiber reactive dyes fix in a level, uniform fashion.

  • Patent number: 5213581
    Abstract: Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.
