  The invention relates to a low-shrinkage polyester industrial yarn and its preparation method. The preparation method comprises the following steps: subjecting the modified polyester to polycondensation, melting, measuring, extruding, cooling, oiling, stretching, heat setting and winding, wherein the oil agent used in oiling contains crown ether, and the content of the crown ether is 67.30 to 85.58 wt%. The preparation method of the invention is simple and feasible, and the dry shrinkage rate of the low shrinkage polyester industrial yarn is 2.5∼4.7% under the environment of 190°C, 15 min and 0.01 cN/dtex, and the material is modified polyester, the molecular chain of the modified polyester includes a terephthalic acid segment, an ethylene glycol segment, and a branched diol segment, and the structural formula of the branched diol is as follows: Wherein R1 and R2 are each independently selected from a linear alkylene group having 1 to 3 carbon atoms, R3 is selected from an alkyl group having 1 to 5 carbon atoms, and R4 is selected from the alkyl group consisting of 2 to 5 carbon atoms.

  The invention introduces a method for improving the quality of a polyester industrial yarn. First, in the cooling process of preparing a polyester industrial yarn prepared by polyester spinning, the longitudinal height is kept unchanged, and the cross-sectional area of the slow cooling chamber is enlarged. The chamber maintains the surface temperature of the spinneret by means of heat preservation, and then uses an oil agent containing 67.30∼85.58wt% crown ether in the oiling process of polyester industrial yarn prepared by polyester spinning. Enlarging the cross-sectional area of the slow-cooling chamber refers to the cross section of the slow cooling chamber is changed from a circular shape to a rectangular shape while keeping the spinneret connected to the slow cooling chamber unchanged. The cleaning cycle of the spinneret is prolonged by 35∼45%, the full package rate of polyester industrial yarn is larger than 99%. This method is simple and reasonable, and it improves the quality of the produced fiber, and worth being promoted.

  本发明介绍了一种提高涤纶工业丝质量的方法。首先，在涤纶纺丝制备涤纶工业丝的冷却过程中，保持纵向高度不变，扩大慢冷室的横截面积。慢冷室通过保温来保持喷丝板的表面温度，然后在涤纶纺丝制备涤纶工业丝的上油过程中使用含 67.30 ∼ 85.58wt% 冠醚的油剂。增大缓冷室的横截面积是指在保持与缓冷室相连的喷丝板不变的情况下，将缓冷室的横截面由圆形变为矩形。喷丝板的清洗周期延长了 35∼45%，涤纶工业丝的全包率大于 99%。该方法简单合理，提高了生产纤维的质量，值得推广。

  The present invention relates to a composition including quantum dots and an emission stabilizer, products including same, and methods, including methods for improving, or enhancing the emission stability of quantum dots. Inclusion of an emission stabilizer in a composition can improve or enhance the stability of at least one emissive property of the quantum dots in the composition against degradation compared to a composition that is the same in all respects except that it does not include the emission stabilizer. Examples of such emissive properties include, by way of example only, lumen output, lumen stability, color point (e.g., CIE x, CIE y) stability, wavelength stability, FWHM of the major peak emission, absorption, solid state EQE, and quantum dot emission efficiency.
