Problems solved by technology

However, the chemical composition of down is a kind of protein, accompanied by animal fat. Even after degreasing and cleaning processes in the pretreatment process, impurities and bacteria cannot be completely eliminated.
Moreover, if it is not dried regularly during use, it is easy to breed bacteria and produce peculiar smell at the same time
[0003] At present, the reported anti-mold and deodorizing processing methods of down mainly use inorganic antibacterial agents and natural antibacterial agents to treat down fibers. Among them, the inorganic antibacterial agents are represented by silver-based inorganic antibacterial agents. Fiber binding is low and processing costs are high
Natural antibacterial agents are represented by chitin, although the processing cost is low, but the binding fastness to down fibers is poor, and the antibacterial and deodorant action time is short

Embodiment 1

[0024] (1) Down degreasing treatment: heat the degreasing agent to 35-40°C and mix for 5 minutes, then add the down that has been sterilized by high temperature and high pressure, so that the down is completely immersed in the degreasing agent, take out the down after 10 minutes, and wash it twice , and dried at 70-75°C;

[0025] (2) Preparation of antibacterial and deodorant treatment liquid: add boiling water to the antibacterial and deodorant finishing agent under stirring, so that the weight water content of the obtained antibacterial and deodorant treatment liquid reaches 65-70%, and naturally cool to room temperature;

[0026] (3) Down antibacterial and deodorizing treatment: crush 1kg of degreased down into coarse powder, pass through a 100-mesh sieve, then spray 0.05kg of antibacterial and deodorant treatment solution, mix thoroughly, and heat up at a rate of 2-3°C / min Heat up to 65-70°C and keep mixed for 15 minutes, then add water at 15-20°C dropwise at a rate of 2-3...

Embodiment 2

[0032] (1) Down degreasing treatment: heat the degreasing agent to 35-40°C and mix for 5 minutes, then add the down that has been sterilized by high temperature and high pressure, so that the down is completely immersed in the degreasing agent, take out the down after 10 minutes, and wash it twice , and dried at 70-75°C;

[0033] (2) Preparation of antibacterial and deodorant treatment liquid: add boiling water to the antibacterial and deodorant finishing agent under stirring, so that the weight water content of the obtained antibacterial and deodorant treatment liquid reaches 65-70%, and naturally cool to room temperature;

[0034](3) Down antibacterial and deodorant treatment: crush 1.5kg of degreased down into coarse powder, pass through a 100-mesh sieve, then spray 0.1kg of antibacterial and deodorant treatment solution, mix thoroughly, and heat up at 2-3°C / min Heat up to 65-70°C and mix for 15 minutes, then add water at 15-20°C dropwise at a rate of 2-3ml / min under stirri...

Embodiment 3

[0072] The eiderdown fiber of embodiment 1, embodiment 2, comparative example 1, comparative example 2 is carried out to measure the feather residual fat rate respectively, and measure embodiment 1, embodiment 2, comparative example 1, comparative example 2, comparative example 3 and The bacteriostatic rate of down fiber made in comparative example 4 to Staphylococcus aureus, Candida albicans and E. The bacteriostatic rate of coccus and Escherichia coli, the results are shown in Table 1.

Abstract

The invention discloses a preparation method of down fiber for processing an antibacterial and deodorant duvet, and relates to the technical field of duvet processing. The preparation method comprises: (1) down degreasing treatment; (2) antibacterial and deodorant treatment solution preparation; (3) antibacterial and deodorant treatment of down; and (4) antibacterial and deodorant down fiber molding. According to the present invention, the prepared antibacterial and deodorant down fiber has excellent antibacterial and deodorant effects, the average antibacterial rate of the antibacterial and deodorant down fiber on Staphylococcus aureus, Candida albicans and Escherichia coli can achieve more than 99%, the average antibacterial rate of the duvet prepared from the prepared antibacterial and deodorant down fiber on Staphylococcus aureus, Candida albicans and Escherichia coli can achieve more than 97% after the duvet is normally used for 1 year, and the average antibacterial rate of the duvet prepared from the prepared antibacterial and deodorant down fiber on Staphylococcus aureus, Candida albicans and Escherichia coli can achieve more than 95% after the duvet is normally used for 3 year.

Description

Technical field: [0001] The invention relates to the technical field of down quilt processing, in particular to a preparation method of down fiber for antibacterial and deodorant down quilt processing. Background technique: [0002] Down is a good natural thermal insulation material, which has the advantages of light weight, softness, and good thermal insulation. Therefore, duvet is the best choice for consumers to keep warm bedding. However, the chemical composition of down is a kind of protein, accompanied by animal fat. Even after degreasing and cleaning processes in the pretreatment process, impurities and bacteria cannot be completely eliminated. Moreover, if it is not dried regularly during use, it is easy to breed bacteria and produce peculiar smell. [0003] At present, the reported anti-mold and deodorizing processing methods of down mainly use inorganic antibacterial agents and natural antibacterial agents to treat down fibers. Among them, the inorganic antibacter...
