preparation example Construction

[0050] A second aspect of the present application provides a method for preparing a quilt, comprising the following steps:

[0051] Prepare SMS non-woven fabric, carry out embossing and perforation process to SMS non-woven fabric, obtain heat-insulating breathable layer, and / or

[0052] Prepare the melt-blown cloth to obtain the thermal insulation and air-permeable layer;

[0053] A heat-preserving and air-permeable layer is stacked between two anti-slip layers to form a sandwich structure, and the quilt is obtained by sewing.

[0054] In the embodiment of the present application, the anti-skid layer is SMS non-woven fabric after embossing, and the surface of the anti-skid layer facing the heat-insulating and air-permeable layer has some first protrusions, which increases the frictional force between the heat-insulating and air-permeable layer. Make the quilt more uniform overall.

[0055] The preparation method of the quilt provided by the application, compared with the pro...

Embodiment 1

[0075] The process of preparing SMS non-woven fabric is as follows: polypropylene raw material + auxiliary functional masterbatch → melting → filtering → metering pump → spinning → cooling → air drafting → web laying → hot rolling → adding antistatic agent and drying → collecting Rolling and slitting → packing.

[0076] Specifically, the S layer (spunbonded layer) is made through steps: add 10-20% auxiliary functional masterbatch to polypropylene PP and mix, auxiliary functional masterbatch includes elastic material and soft masterbatch, elastic material and soft The ratio of masterbatch is 25:6, and the components of flexible masterbatch are composed of the following: 60.5% of polypropylene homopolymerization and copolymerization mixture, 22.5% of fatty acid amino derivatives, 15% of polyolefin derivatives, 2% of plastic dispersants, after extrusion The machine is heated and heated to 180-240°C to melt into flowing molten polypropylene, filtered through a filter, and then spu...

Embodiment 2

[0083] Change the thickness of the prepared SMS non-woven fabric, and the remaining steps are the same as in Example 1. The total thickness of the prepared quilt is 1.71mm, the air permeability is 349.98mm / s, the thermal insulation performance is 0.0824㎡.k / w, the softness is 15.42mg / cm, and the elasticity 80%.

Abstract

The invention belongs to the technical field of bedding articles, and particularly relates to a quilt and a preparation method thereof. The cotton quilt comprises two anti-skid layers and one or more heat preservation breathable layers arranged between the two anti-skid layers. The anti-skid layer and the heat preservation breathable layer are made of non-woven fabric, and the heat preservation breathable layer is made of SMS non-woven fabric and / or melt-blown fabric. The product has the fluffy, soft and skin-friendly effects, is high in heat preservation value, good in antistatic property, elasticity and toughness, light in weight, small in size after being folded, easy to carry and suitable for being used by business trips, family travels or hospital patients in a disposable mode. The product can also be used as an aircraft blanket, is clean and sanitary, avoids cross infection, can be cleaned for multiple times for recycling, and is economical and environment-friendly.

Description

technical field [0001] The application belongs to the technical field of bedding, and in particular relates to a cotton quilt and a preparation method thereof. Background technique [0002] As we all know, cotton quilts are used as coverings during sleeping and have a certain effect of keeping warm. There are many kinds of quilts on the market, most of which are cotton quilt cores. Of course, there are also silk quilts and so on. The core quilt mainly has the following disadvantages. The quilt made of pure cotton has poor antibacterial properties and poor air permeability; and after a long period of use, the cotton quilt core will move inside, resulting in thinner cotton in some places and thinner cotton in some places. Thick, poor uniformity, and easy to breed some germs. If it is a sick patient, the cotton wick quilt is easy to breed bacteria and germs, which is not conducive to the recovery of the patient. At the same time, a set of quilts are used repeatedly by many peop...
