Embodiment 1

[0032] A preparation method for seersucker, the steps are as follows:

[0033] (1) Preparation of polyester low elastic yarn:

[0034] In the process of preparing fibers from PET with an intrinsic viscosity of 0.6dL / g according to the FDY process, the ring air is used to cool, and the arrangement of the spinneret holes on the spinneret is controlled to meet certain conditions. After the FDY filaments are prepared, the temperature is 90 ℃, relaxation heat treatment for 30min to obtain polyester low elastic yarn;

[0035] The spinneret hole is a crescent-shaped spinneret hole and an "H"-shaped spinneret hole. The cross-section of the crescent-shaped spinneret hole is surrounded by an outer arc M and an inner arc N. The outer arc M and the inner arc N are The two intersection points are A and B respectively, and the length of the line segment AB is 0.091mm;

[0036] The certain conditions are: all the spinneret holes are distributed in concentric circles, the number of 30 cresc...

[0048] A preparation method for seersucker, the steps are as follows:

[0049] (1) Preparation of polyester low elastic yarn:

[0050] In the process of preparing fibers from PET with an intrinsic viscosity of 0.69dL / g according to the FDY process, the ring air is used to cool, and the arrangement of the spinneret holes on the spinneret is controlled to meet certain conditions. After the FDY filaments are obtained, the temperature is 91 ℃, relaxation heat treatment for 30min to obtain polyester low elastic yarn;

[0051] The spinneret hole is a crescent-shaped spinneret hole and an "H"-shaped spinneret hole. The cross-section of the crescent-shaped spinneret hole is surrounded by an outer arc M and an inner arc N. The outer arc M and the inner arc N are The two intersection points are A and B respectively, and the length of the line segment AB is 0.089mm;

[0052] A certain condition is: all the spinneret holes are distributed in concentric circles, the number is 48. The cre...

[0064] A preparation method for seersucker, the steps are as follows:

[0065] (1) Preparation of polyester low elastic yarn:

[0066] In the process of preparing fibers from PET with an intrinsic viscosity of 0.6dL / g according to the FDY process, the ring air is used to cool, and the arrangement of the spinneret holes on the spinneret is controlled to meet certain conditions. After the FDY filaments are produced, the temperature is 104 ℃, the relaxation heat treatment time is 25min to obtain polyester low elastic yarn;

[0067] The spinneret hole is a crescent-shaped spinneret hole and an "H"-shaped spinneret hole. The cross-section of the crescent-shaped spinneret hole is surrounded by an outer arc M and an inner arc N. The outer arc M and the inner arc N are The two intersection points are A and B respectively, and the length of line segment AB is 0.086mm;

Abstract

The invention relates to a preparation method of seersucker. The preparation method comprises the steps of knitting 8.3 tex polyester drawn textured yarn and 14.5 tex combed cotton yarn to prepare theseersucker; the threading mode is as follows: the 1F, 13F, 25F and 42F threads the polyester drawn textured yarn, and the rest threads the combed cotton yarn; the preparation process of the polyesterdrawn textured yarn comprises the steps of, in the process of preparing fiber from PET according to an FDY process, cooling by adopting cross air blowing, controlling spinneret orifices in the spinneret plate to be arranged in the mode that all the spinneret orifices are distributed in concentric circles, the crescent spinneret orifices are positioned in the circle of the outermost circle, the other crescent spinneret orifices rotate by different angles relative to one of the crescent spinneret orifices, and after FDY is prepared, carrying out relaxation heat treatment to obtain the polyesterdrawn textured yarn; and the spinneret orifices comprise crescent spinneret orifices and H-shaped spinneret orifices. The preparation method is simple, and the problem that in the prior art, when thehand feeling fullness is improved, the refreshing feeling of the seersucker is reduced is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of textile yarns, and relates to a preparation method of seersucker yarns. Background technique [0002] Seersucker is a traditional textile with unique organizational structure, unique appearance and good wearing performance. There are two groups of seersucker fabric structures: ground weave fabrics and seersucker weave fabrics. The bubble fabric is wavy, so that there is a certain space between the fabrics. When worn, the fabric does not cling to the skin, allowing air to flow and ventilating. Therefore, seersucker has been widely used in summer clothing. Due to the unique aesthetic effect of the appearance of seersucker, it has been widely used in sportswear and casual clothing, as well as home textiles in recent years. [0003] Generally, the bubble warp yarn is thicker than the ground warp yarn, so that the cloth at the bubble warp is tighter; and because the bubble warp let-off is large, the bubble...
