    摘要: A method for decolorizing a polyester fabric is provided, which includes: providing a dyed polyester fabric, in which a material of the dyed polyester fabric contains a dye and a water repellent; providing a composite solvent, in which the composite solvent includes propylene glycol methyl ether (PM) and acetic acid that are mixed together; and performing an extraction process, which includes using the composite solvent to wet the dyed polyester fabric and remove the dye and the water repellent from the material of the polyester fabric by extraction, so as to obtain a reduced polyester fabric.

    摘要: A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

    摘要: Disclosed are a polyester cotton-like yarn-dyed fabric, and a manufacturing method and application thereof. The polyester cotton-like yarn-dyed fabric is interwoven by warp and weft, the warp adopts dyed polyester as a covering layer and low-temperature spandex as a core-spun yarn of a core yarn, a weight ratio of the polyester to the low-temperature spandex is 4-49:1, and the polyester is subjected to alkali deweighting treatment to form an eroded surface. The polyester cotton-like yarn-dyed fabric has good cotton feeling, high elasticity, high color fastness and low ironing shrinkage rate, and is suitable for making high-quality clothing, especially shirts. The manufacturing method of the yarn-dyed fabric is energy-saving and emission-reducing, and can manufacture a novel polyester yarn-dyed fabric with low ironing shrinkage rate, high color fastness and cotton-like hand feeling. Use of the yarn-dyed fabric for making clothing such as shirts increases the selectivity and functionality.
