Oxygen-absorbing film
An oxygen-absorbing film having an oxygen-absorbing adhesive agent layer including a cured oxygen-absorbing adhesive agent resin composition, wherein the oxygen-absorbing adhesive agent layer has at least two glass transition temperatures, and wherein the lowest glass transition temperature among the glass transition temperatures is lower than 0? C. The cured oxygen-absorbing adhesive agent resin composition preferably includes: (A) an oxygen-absorbing polyester resin having a glass transition temperature of ?20 to 10? C. and (B) a saturated polyester resin having a glass transition temperature of ?10? C. or lower. The oxygen-absorbing polyester-based resin (A) is made from a tetrahydrophthalic acid, a derivative thereof, a tetrahydrophthalic anhydride, or a derivative thereof, and the saturated polyester resin (B) containing a structural unit derived from a diol component and a structural unit derived from a dicarboxylic acid component is preferably selected from the group consisting of adipic acid, sebacic acid, isophthalic acid, and combinations thereof.

METHOD FOR PRODUCING TEXTILE PRODUCTS, PRODUCTS OBTAINABLE THEREFROM AND METHOD TO RECLAIM THE PRODUCTS
The present invention pertains to a method for manufacturing a laminated textile product comprising providing a first intermediate product comprising a primary backing having a front surface and a back surface, and yarns stitched into the primary backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the said heated surface, to at least partly melt the yarns present in the intermediate product to bond the yarns to the backing, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, so as to provide a second intermediate product having a calendered back surface, providing a dimensionally stable carrier sheet or secondary backing, and connecting the second intermediate product to the carrier sheet by providing a hot melt adhesive between the calendered surface and the sheet, and pressing the sheet to the second intermediate product to form the textile product.
Copolyester hot-melt adhesive and preparation method therefor
A novel copolyester hot-melt adhesive and a preparation method thereof are disclosed. The preparation method mainly includes the following steps: selecting raw materials according to preset ratios, wherein the raw materials include: bisphenol A, maleic acid, terephthalic acid, another dibasic acid, 1,4-butanediol, another dibasic alcohol, catalysts and a stabilizer; producing a prepolymer under negative pressure in a low-temperature section, completing an esterification process under normal pressure in the low-temperature section, and completing a polycondensation step under negative pressure in a high-temperature section, thereby finally preparing the novel copolyester hot-melt adhesive product. According to the disclosed copolyester hot-melt adhesive product, on the basis of maintaining the comprehensive performance of the existing conventional copolyester hot-melt adhesive products, the dry cleaning resistance is greatly enhanced, and is no less than the washing resistance of a polyamide hot-melt adhesive, but the overall cost is lower than that of the conventional polyamide hot-melt adhesives.
COMPOSITION COMPRISING ACTIVATED AND FUNCTIONALIZED PRE-POLYMER
The present disclosure relates to a composition comprising: a pre-polymer having activated groups and negatively-charged functional groups on a polymeric backbone. The present disclosure also relates to a method for preparing such a composition.
