Example 1

Referring to fig. 1-2, the present invention provides a composite blanket, which comprises a middle layer 100, a cool layer 200 and a warm layer 300. The middle layer 100 comprises a chain 110 and a weft insertion 120 made of polyester materials, the chain 110 and the weft insertion 120 are interwoven in a warp-weft mode, the chain 110 enables the longitudinal dimension of the fabric to be stable, and the transverse deformation rate is correspondingly reduced. The intermediate layer 100 also includes oppositely disposed first and second sides, the intermediate layer 100 having a warp density of 10-12 (i.e., number of coils per centimeter) and a weft density of 8-10 (i.e., number of coils per centimeter). The cooling layer 200 is disposed on the first side of the middle layer, and the cooling layer 200 is used to provide cooling performance. The thermal insulation layer 300 comprises a cotton pile structure 310, the pile structure 310 is disposed on the second side of the middle layer, the pile structure 310 is connected with the middle layer 100, and the height of the pile in the pile structure 310 is 5-12 mm.

The utility model discloses in, the dacron adopts PET fully drawn yarn, because fully drawn yarn has been by abundant tensile, the whole powerful height of fibre, and adopts the dacron as the intermediate level, and the broken intensity of fabric promotes by a wide margin, but does not have the influence basically to fabric surface cotton fiber's hydroscopicity and compliance.

In this embodiment, the cooling layer 200 includes a cured layer and cooling microcapsules, the thickness of the cooling layer 200 is 3 to 5mm, the cured layer is laid on the first side of the middle layer 100, and the cooling microcapsules are fixed to the cured layer. The cured layer includes a thickener and a binder that cure into a layered structure.

In this embodiment, the cool microcapsule has a capsule wall layer structure and a core layer structure, and the capsule wall layer structure is disposed on the outer surface of the core layer structure. More specifically, the wall layer structure is wrapped around the outer surface of the core layer structure.

In this example, the thickener was purchased from Lyoprint ATP-30, a zero VOC emission environmentally friendly thickener from Hounsfield. The adhesive is O/W type emulsion, the inner phase is polymer particles, and the outer phase is water. The wall material of the cool microcapsule is polyurethane, and the core material is paraffin.

In one embodiment, in the composite blanket, the mass of the terylene accounts for 0 to 5 percent of the total mass of the terylene and the cotton. The polyester quality is controlled within 5 percent, the composite blanket still belongs to the category of cotton materials, and the purpose of improving the shrinkage rate of the fabric can be achieved. Specifically, in this embodiment, the mass of the polyester fiber accounts for 4.7% of the total mass of the polyester fiber and the cotton fiber.

The manufacturing process flow of the composite blanket in the embodiment 1 comprises the following steps: warping → weaving blank → slitting → dyeing → steaming → washing → drying → heat preservation layer brush hair → cool feeling layer microcapsule cool feeling printing arrangement → finished product shaping → wrapping.

In the blank weaving process, an RD6DPLM/22 type double needle bed Raschel warp knitting machine is adopted for weaving, the adjustable range of the height of the fluff is 5-12 mm, wherein four ground combs are respectively woven on corresponding front and back needle beds to form an intermediate layer 100, and the intermediate layer 100 consists of a fully-penetrated chain 110 and weft insertion 120. The yarns 30D/12F for the knitted chain 110, 20D/17F for the weft insertion 120, and 40Ne/2 compact siro-spun cotton yarn for the spacer yarn 400 were used.

In the slitting process, the fabric is carded on a loom at the speed of 6m/min. Because the fabric obtained by the blank weaving process is a sandwich structure of middle layer-spacing yarn-middle layer, referring to fig. 3, the slitting process is to divide one part of the sandwich structure into two parts, so as to form two fabrics of ground weave-pile structure, i.e. the slitting process is to cut the fabrics of the sandwich structure at the position of the spacing yarn, so as to obtain the fabric of ground weave-pile structure with pile of a certain length. The pile structure in the ground tissue-pile structure is the pile structure 310 in the present invention.

In the steaming process, saturated steam with the temperature of 102-105 ℃ is adopted as the steaming temperature, and the steaming time is 5-7 min. In the steaming process, the color paste printed on the surface of the fabric absorbs water and swells, and the dye is dissolved in the pattern range of the color paste and is diffused and permeated into the fiber. Meanwhile, the macromolecular structure of the fiber has enlarged internal gaps under the damp and hot conditions, so that the dye is received and is combined with the dye through various chemical bonds, and the dye is fixed on the fiber.

In the cool feeling layer microcapsule cool feeling printing finishing process, the printing finishing prints slurry on the first side of the middle layer in a pigment printing mode, and the slurry comprises a thickening agent, an adhesive, cool feeling microcapsules and the balance of water. Wherein, in the manufacturing process of the composite blanket, the cool microcapsule accounts for 50% of the total mass of the slurry, the mass ratio of the cool microcapsule to the adhesive is 2. The computer-operating condition parameters comprise: the thickness of the coating is controlled between 3 mm and 5mm, the pre-baking condition is 70 ℃ to 90 ℃, the time is controlled between 6 min and 8min, and the baking condition is 130 ℃ to 150 ℃.

In the process for producing the composite carpeting of example 1, the height of the piles in the pile structure 310 and the density of the intermediate layer 100 were adjusted to control the PET content within 5%, and the shrinkage of the cotton carpet, which contained 5% of the PET content, was measured by GB/T8628-2013, as compared with 100% pure cotton carpet, and the pile retention performance was rated 4, as shown in table 1. The contact cooling performance of the cooling layer 200 of the composite blanket was tested, and the results are shown in table 2 below, in which the average value of the cooling coefficient was 0.24, which meets the standard.
