  • 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: RE45243
    Abstract: The invention relates to a method for producing a towel, specifically a low twist towel, comprising the following steps: Z twisting a thick yarn and separately Z twisting a fine count yarn; unevenly S twisting the Z-twisted yarns to make the volume of the thick yarn more than that of the fine count; weaving the yarn to produce a fabric; processing the fabric with hot water to reduce inner tension in the yarn and make the fabric become fluffy. Fabric produced by this method can solve the dependency on PVA, reduce energy consumption and material consumption, and prevent water pollution. This method for producing a low twist towel is environmentally friendly, healthy, and energy saving.
