Embodiment 1

[0036] A preparation method of a blanket, the steps are as follows:

[0037] (1) Preparation of PTT FDY silk:

[0038] In the process of preparing fibers from PTT with an intrinsic viscosity of 0.92dL / 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, and PTT FDY filaments are obtained;

[0039] The spinneret hole is a C-shaped spinneret hole. The cross-section of the C-shaped spinneret hole is surrounded by an outer arc M, an inner arc N and two line segments. The two ends of M are A and B respectively, and the length of the line segment AB is 0.11. mm;

[0040]Certain conditions are: a circle of equidistantly distributed C-shaped spinneret holes is arranged on the spinneret plate, the number is 24, and the straight line where two points A and B are located on the cross-section of any C-shaped spinneret hole is used as the reference line. On the cross-section of ...

[0049] A preparation method of a blanket, the steps are as follows:

[0050] (1) Preparation of PTT FDY silk:

[0051] In the process of preparing fibers from PTT with an intrinsic viscosity of 0.98dL / 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, and PTT FDY filaments are obtained;

[0052] The spinneret hole is a C-shaped spinneret hole. The cross-section of the C-shaped spinneret hole is surrounded by an outer arc M, an inner arc N and two line segments. The two ends of M are A and B respectively, and the length of the line segment AB is 0.11. mm;

[0053] Certain conditions are: a circle of equidistantly distributed C-shaped spinneret holes is arranged on the spinneret plate, the number is 24, and the straight line where two points A and B are located on the cross-section of any C-shaped spinneret hole is used as the reference line. On the cross section of...

Embodiment 3

[0062] A preparation method of a blanket, the steps are as follows:

[0063] (1) Preparation of PTT FDY silk:

[0064] In the process of preparing fibers from PTT with an intrinsic viscosity of 0.95dL / 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, and PTT FDY filaments are obtained;

[0065] The spinneret hole is a C-shaped spinneret hole. The cross-section of the C-shaped spinneret hole is surrounded by an outer arc M, an inner arc N and two line segments. The two ends of M are A and B respectively, and the length of the line segment AB is 0.11. mm;

[0066] Certain conditions are: a circle of equidistantly distributed C-shaped spinneret holes is arranged on the spinneret plate, the number is 24, and the straight line where two points A and B are located on the cross-section of any C-shaped spinneret hole is used as the reference line. On the cross section of...

Abstract

The invention relates to a preparation method of a blanket. The raw materials are top yarn and bottom yarn, the top yarn is PTT FDY yarn with a shrinkage rate of 3-5%, and the bottom yarn is polyester full-drawn yarn with a shrinkage rate of 20-30%. The process flow is: weaving into gray cloth → cutting → brushing → ironing → printing → finishing → drying → steaming → washing → dehydration → setting and drying → brushing → ironing → scissors → cloth cutting → hemming → finished product; The preparation process of PTT FDY filaments is as follows: in the process of preparing fibers from PTT according to the FDY process, use ring blowing to cool, and control the arrangement of C-shaped spinneret holes on the spinneret to meet certain conditions (random rotation at different angles) , to produce PTT FDY wire. The thermal resistance of the final blanket is 0.468-0.5131K m 2 / W, the plumpness is 4.5-5.0, and the softness is 4.5-5.0.

Description

technical field [0001] The invention belongs to the technical field of polyester fibers and relates to a preparation method of a blanket. Background technique [0002] Generally speaking, the functionalization of textiles is mainly achieved in two ways: one is the functional finishing of fabrics, but the functionalization and differentiation of textile fibers; the former is exposed to many environmental burdens due to the use of chemicals. There are more and more limitations, and the latter has no environmental problems in the process of realizing functionality, so it is more and more accepted by people. [0003] In the field of Raschel blankets, along with the development of new raw materials and the maturity of application technology, its market area is constantly expanding. Today's consumers require Raschel blankets to have a full suede, soft and comfortable feel and the compression back of the fabric. Good elasticity and other characteristics. [0004] Therefore, it is...
