    Abstract: 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.

  • Patent number: 10161792
    Abstract: The present invention discloses a device and a method for realizing spectral polarization-independent measurement based on a frequency domain depolarization structure. The device comprises a pump light source module, a depolarization module, an SBS effect generation module and a data acquisition and spectrum reconstruction module. The method comprises: emitting laser light having a fixed polarization state from the pump light source module; the laser light from an output end of the pump light source module passing through the depolarization module to become depolarized light; inputting the depolarized light as pump light into the SBS effect generation module to interact with signal light under test input from the outside into the SBS effect generation module; and after amplifying the signal light under test through the SBS effect generation module, performing data acquisition processing through the data acquisition and spectral reconstruction module and finally obtaining a spectrum of a signal under test.

  • Patent number: 10122445
    Abstract: A method for enhancing optical signal-to-noise ratio measuring precision by correcting spectral resolution is provided, which can obtain optical signal-to-noise ratio with enhanced measuring precision, by measuring actual power of broad spectrum signals in a certain bandwidth, determining the sum of the power of the sampling points for the broad spectrum signals in the bandwidth by using an optical spectrum analyzer, obtaining the corrected resolution of the optical spectrum analyzer, and replacing the setting resolution of the optical spectrum analyzer with the corrected resolution. The method can effectively solve the problem of large OSNR measuring error resulted from the difference between the setting resolution and the actual resolution of optical spectrum analyzer.

  • Patent number: 9985243
    Abstract: An encapsulation method of an OLED and an OLED device are provided, and the method includes: providing a substrate for encapsulation (401) and a cover plate (403); forming a conductive frame (402) on the substrate for encapsulation (401); cell assembling the substrate for encapsulation (401) which is provided with the frame (402) and the cover plate (403) to obtain a preforming device; placing the preforming device into a plating tank, and energizing the frame (402), wherein a metal thin film (404) is formed on a surface of the frame (402) close to the outside edge of the substrate (401). A layer of metal film (404) is plated at the periphery of the frame (402). Because the blocking effect of the compact structure of the metal thin film (404) to water and oxygen is better than that of a sealing frame cement, thus an OLED device made by the encapsulation method has better sealing effect and better performance.
