Description

Technical Field

[0001] The present invention relates to the technical field of duvet fabrics, and particularly relates to an insect-proof and mite-proof duvet fabric and a preparation method thereof. Background Art

[0002] A duvet consists of a core and a fabric. The filling of the core is mainly down. Since the chemical composition of down is a kind of protein and accompanied by animal fat, even after degreasing and washing processes in the pretreatment, the fat and bacteria cannot be completely removed. Therefore, it is necessary to perform insect-proof and mite-proof treatments on the duvet fabric to prevent insects and mites from breeding on the fabric surface or even damaging the internal down through the fabric. Although the existing duvet fabrics have certain insect-proof and mite-proof effects after the treatment, the anti-feather leakage performance and anti-wrinkle performance of the duvet fabrics after the insect-proof and mite-proof treatment still cannot be guaranteed, resulting in the internal filled down being extremely easy to drill out from the fabric, affecting the normal use and aesthetic degree of the duvet. Summary of the Invention

[0003] The main purpose of the present invention is to provide an insect-proof and mite-proof duvet fabric and a preparation method thereof, which can effectively solve the problems in the background art.

[0011] As a further optimization solution of the present invention, the ionizing radiation in step S3 is γ-ray, X-ray or electron beam.

[0012] As a further optimization solution of the present invention, the irradiation dose of the ionizing irradiation is 4k-10kGy.

[0013] As a further optimization solution of the present invention, the temperature is raised to 50-55°C in step S3, and the stirring rate is 300-800 r / min.

[0015] As a further optimization solution of the present invention, in step S3, the modified insect and mite proofing agent is used to replace the insect and mite proofing agent in equal amount.

[0016] As a further optimization solution of the present invention, the weight ratio of sulfonated phenolic resin to nano-sized diatomaceous earth in step S4 is 1:(1.2-1.5).

[0017] As a further optimization solution of the present invention, the weight ratio of nano-sized diatomaceous earth to the insect and mite proofing agent in step S4 is 1:(1.5-2).

[0081]

[0082] Based on the above experimental data, the following conclusions are drawn:

[0083] From Examples 1-5, Comparative Examples 1-3, and the control group, it can be seen that the feather leakage quality of the fabrics in Examples 1-2 is below 1000 mg, and the average crease recovery angle of the front and back sides reaches below 120, and the crease recovery angle of the front and back sides is not high. While in Examples 3-5, the crease recovery angle of the front and back sides of the fabrics has increased significantly. In Example 5, the average crease recovery angle of the front and back sides of the fabric reaches 174.1, and the feather leakage quality reaches 640 mg. Comparing Example 5 with Comparative Example 1, Comparative Example 2, or Comparative Example 3, it can be seen that adding alkyl sulfonate and fatty acid polyol ester to the anti-insect and anti-mite finishing agent or modifying the prepared anti-insect and anti-mite finishing agent can improve the anti-feather leakage performance of the fabric while enhancing the wrinkle resistance performance of the fabric. Comparing the control group with Comparative Example 1, Comparative Example 2, or Comparative Example 3 respectively, it can be seen that the crease recovery angle of the fabric in the control group has decreased significantly, and the fabric is extremely prone to feather leakage. It can be seen that adding alkyl sulfonate and fatty acid polyol ester to the anti-insect and anti-mite finishing agent, irradiating it, and then modifying the anti-insect and anti-mite finishing agent with nano-scale diatomaceous earth carrying sulfonated phenolic resin can significantly improve the anti-wrinkle deformation performance and anti-feather leakage performance of the fabric; and it can be seen from Example 5 and Comparative Example 1, Comparative Example 2, or Comparative Example 3 that the modified anti-insect and anti-mite finishing agent can still maintain good acaricidal performance.
