Embodiment 1

[0031] A preparation method of polyester crepe chine woven fabric,

[0032] (1) The preparation process of disperse dye normal pressure dyeable polyester fiber is as follows:

[0033] The normal pressure dyeable polyester melt (intrinsic viscosity is 0.65dL / g) is extruded from the three-lobed spinneret hole on the spinneret and cooled by ring blowing; wherein, in the preparation process of the normal pressure dyeable polyester, the The mol ratio of phthalic acid, isophthalic acid and diethylene glycol is 100:3:5, and the addition of polyethylene glycol is 9wt% of the addition of terephthalic acid;

[0034] The ratio of the included angle of the center line of the three lobes of the same three-lobed spinneret hole is 1.0:1.4:1.6, the length and width of the three lobes are the same and the ratio of length to width is 3:1; different three-lobed spinneret holes The shape and size of the three lobes are the same; all the three-lobed spinneret holes are distributed in concentric c...

Abstract

The invention relates to a preparation method of a polyester Crepe DE chine machine fabric. The preparation method comprises the following steps of firstly making disperse-dye easily dyeable polyesterfibers under normal pressure into S-twist and Z-twist spiral wefts respectively, making the polyester silk-like silk into warps, then interweaving the helical wefts twisted in opposite directions with each other and the warps into the fabric, and finally, dyeing the fabric to prepare the polyester Crepe DE chine machine fabric; the S-twist and the Z-twist spiral wefts have a twist of 300 to 500 twist/m; the preparation process of the disperse-dye easily dyeable polyester fibers under normal pressure is as follows: extruding an easily dyeable polyester melt under normal pressure from a trilobal spinneret orifice on a spinneret plate, then cooling the easily dyeable polyester melt under normal pressure by using cross air blow, and preparing the disperse-dye easily dyeable polyester fibers under normal pressure according to an FDY process; and after dyeing, the disperse-dye easily dyeable polyester fibers under normal pressure have a three-dimensional crimp shape. According to the preparation method of the polyester Crepe DE chine machine fabric provided by the invention, the problems in the prior art that when the Crepe DE chine machine fabric is prepared, the quality of the fibersand the style of the fabric are destroyed due to a heavy twist process are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a preparation method of polyester crepe chine woven fabrics. Background technique [0002] Crepe Chine woven fabrics are generally thin silk-like fabrics, the warp is made of untwisted or weakly twisted fibers, and the weft is made of strong twisted fibers. When warp and weft are used for weaving, the weft is a left-twisted strong-twisted yarn and a right-twisted strong-twisted yarn alternately woven in, and the fabric structure is usually plain weave; after refining and review, The surface of the fabric is wrinkled, forming micro-concave-convex and wavy wrinkles, and the luster is soft. It can be seen from the processing technology that in order to obtain the style of crepe chine, it is necessary to carry out strong twisting on the weft yarn in different directions (making the twist of the yarn reach 1800 twists / meter), so that it has high twist, but high twist will cause...
