    摘要: New water-dispersible or water-soluble sulphonated polyesters with a number molecular mass lower than 20000, exhibiting a sulphur weight content of the order of 0.5 to 10% and a hydroxyl functional group content, expressed as OH equivalent/kg of polymer, higher than 0.2. They may be employed as antisoiling and/or antiredeposition agents and optionally detergents in detergent compositions, in rinsing, softening or antisoiling treatment compositions, for washing with or without pretreatment, rinsing, softening or the antisoiling treatment of textiles, especially those polyester-based.

    摘要: The process of making the soil-repellent and abrasion-resistant monofilament includes transesterifying dimethylterephthalate with ethylene glycol; adding to the resulting reaction mixture from 0.15 to 5 percent by weight of a polydialkylsiloxane of formula I: --CO--R.sub.1 --�Si(R.sub.2).sub.2 --O!.sub.n --Si(R.sub.2).sub.2 --R.sub.1 --CO-- (I), wherein n is the number of repeated --Si(R.sub.2).sub.2 --O-- groups and R.sub.1 or R.sub.2 represent the same or different radicals with 2 to 20 carbon atoms; then polycondensing to form a linear silicone-modified polyethylene terephthalate in which the polydialkyl siloxane of formula I is inserted into a polyethylene terephthalate polymer chain thereof; and extruding the linear silicone-modified polyethylene terephthalate to form a monofilament consisting of the silicone-modified polyethylene terephthalate having a silicon content of 0.05 to 2.0% by weight. The monofilament product has a cross-section with a diameter of from 0.1 to 1.0 mm, a homogeneous composition over the entire cross-section, a tenacity of at least 36 cN/tex, an elongation of less than 44% based on an unstretched portion and a soiling index of less than 10 after five soiling cycles.

    摘要: Oriented composite polyester films with improved adherence in respect of the various final coatings, comprising on at least one of their faces a primary adherence coating formed by co-extrusion of a common crystallizable polyester and of a copolyester with oxysulfonyl groups comprising, for 100 moles of recurrent units of dicarboxylic acid: a) from 78 to 93 moles of terephthalate units; b) from 2 to 5 moles of units derived from an aromatic diacid with one or a number of oxysulfonyl groups; c) from 5 to 17 moles of units derived from at least one alcanediacarboxylic acid comprising from 4 to 15 carbon atoms. These composite films have applications as a final coating support used in packaging, the graphic arts or metal coatings.
