Embodiment 1

[0037] A kind of preparation method of Raschel blanket, specifically as follows:

[0038](1) Preparation of heat-humid comfortable polyester functional fiber: extrude PET melt (intrinsic viscosity 0.6dL / g) from the trilobal spinneret hole on the spinneret and cool it with ring blowing, and make it according to the FDY process Obtain FDY yarn, that is, obtain hot and humid comfortable polyester functional fiber; wherein, the ratio of the length of the three lobes of the same three-lobed spinneret hole is 1.0:1.1:1.5, the width of the three lobes is the same, and the length and width of the shortest lobe The ratio is 2.6:1, and the angle between the centerlines of two adjacent lobes is 120°; the shape and size of the three lobes of different three-lobed spinneret holes are the same; there is a circle of equidistant three-lobed spinneret holes on the spinneret plate. The number of leaf-shaped spinneret holes is 24, and the central axis of the longest leaf of one of the three-loba...

Abstract

The invention relates to a preparation method of a Raschel blanket. The top yarn is a heat-humid comfortable polyester functional fiber with a shrinkage rate of 3-5%, and the bottom yarn is a fully drawn polyester yarn with a shrinkage rate of 20-30%. The process is: weaving into gray cloth → cutting → brushing → ironing → printing → finishing → drying → steaming → washing → dehydration → setting and drying → brushing → ironing → ironing → cutting cloth → edge wrapping → finished product; Preparation of wet comfortable polyester functional fiber: PET melt is extruded from the three-lobed spinneret hole on the spinneret and then cooled by ring blowing, and it is produced according to the FDY process; the weight of the Raschel blanket is 350-400g / m 2 , the thermal resistance is 0.475~0.501K·m 2 / W, the plumpness is 4.5-5.0 grades, the softness is 4.5-5.0 grades, the compressibility is 53-60%, the compression resilience is ≥90%, and the stiffness is 3.71-4.12 / cm.

Description

technical field [0001] The invention belongs to the technical field of polyester fibers and relates to a preparation method of a Raschel 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] Therefor...
