Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing a breathable fabric and a composite mattress. Background Art

[0002] There are various types of mattresses, among which the fabric (or cloth) used for the mattress surface that contacts the human body needs to have good air permeability. However, the fabrics in the prior art have poor air permeability, which makes the use of such fabrics unfavorable to human health.

[0003] In addition, although some fabrics in the prior art have certain air permeability, it is difficult to meet the requirements of wrinkle resistance at the same time.

[0004] Therefore, it is urgent to provide a new fabric, which has good air permeability and further has good wrinkle resistance. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the above-mentioned prior art. To this end, the present invention provides a method for preparing a breathable fabric and a composite mattress. The fabric prepared by the preparation method of the present invention has good air permeability.

[0006] The inventive concept of the present invention is as follows: the present invention utilizes specific fiber blending spinning to form warp yarn and weft yarn respectively, thereby obtaining a fabric base layer, and then utilizes a modified liquid of specific composition to soak the fabric base layer, so that the modified liquid is in full contact with the components in the fabric base layer, and then a sufficient cross-linking reaction occurs under dry conditions, so that the breathable fabric has good air permeability and good anti-wrinkle performance. The modified liquid includes water-based hydroxy acrylic resin, epoxy resin, auxiliary agent, sodium di(2-ethylhexyl) sulfonate of succinate, silane coupling agent, nano zinc oxide, polydimethylsiloxane and water, and through the hydrolysis of the silane coupling agent and the presence of sodium di(2-ethylhexyl) sulfonate of succinate, the nano zinc oxide is uniformly dispersed in the resin system, and under dry conditions, the water-based hydroxy acrylic resin and the epoxy resin undergo a cross-linking reaction under the action of the auxiliary agent, and the active components containing hydroxyl groups and carboxyl groups in the fabric base layer can also participate in the cross-linking reaction, thereby significantly improving the anti-wrinkle performance of the breathable fabric. The presence of nano zinc oxide contributes to the existence of tiny gaps in the cross-linked product, which is beneficial to improving the breathability of breathable fabrics.

[0007] A first aspect of the present invention provides a method for preparing a breathable fabric.

[0008] Specifically, a method for preparing a breathable fabric comprises the following steps:

[0009] Weaving the warp yarn and the weft yarn to obtain a fabric base layer, then immersing the fabric base layer in a modified liquid for soaking, and drying to obtain the breathable fabric;

[0010] The warp yarn is formed by mixed spinning of polyester fiber, flax fiber and wool;

[0011] The weft yarn is made by mixing polyester fiber, bamboo fiber and wool;

[0012] The modified liquid comprises water-based hydroxy acrylic resin, epoxy resin, auxiliary agent, sodium di(2-ethylhexyl)sulfosuccinate, silane coupling agent, nano zinc oxide, polydimethylsiloxane and water.

[0014] Preferably, the weft yarn is formed by mixing and spinning polyester fiber, bamboo fiber and wool in a weight ratio of 1:(1-1.5):(1-1.5).

[0015] Selecting specific ratios of polyester, linen and wool to make up the warp yarns, and selecting specific ratios of polyester, bamboo and wool can help improve the breathability of breathable fabrics.

[0020] Preferably, the drying process is first drying at 30-50° C. for 20-60 hours, and then drying at 60-80° C. for 2-6 hours. The staged drying helps the modified liquid to fully undergo a cross-linking reaction, thereby facilitating the enhancement of the adhesion strength with the fabric base layer and improving the wrinkle resistance of the fabric.

[0021] Preferably, the warp density of the fabric base layer is 50-65 strands / cm, and the weft density is 30-45 strands / cm; further preferably, the warp density of the fabric base layer is 55-65 strands / cm, and the weft density is 35-40 strands / cm.

[0024] A breathable fabric is prepared by the above preparation method.

[0025] A third aspect of the present invention provides a composite mattress.

[0026] A composite mattress comprises a fiber layer, a meltblown fabric layer and a surface layer composed of the above-mentioned breathable fabric which are arranged in sequence from bottom to top.

The presence of nano zinc oxide contributes to the presence of micro-voids in the cross-linked product, which is beneficial to improving the air permeability of breathable fabric.
