Embodiment 1

[0018] Preparation of chitosan with different molecular weight and degree of acetylation:

[0019] Preparation scheme of chitosan with different molecular weights: high polymer chitosan (molecular weight 1.85×10 5 , the degree of deacetylation is 70%) under the condition of pH 3.0-4.5, the process adopts glacial acetic acid to adjust the pH value, and the concentration is 30% H 2 o 2 Degradation, where high polymer chitosan and 30% H 2 o 2 The mass ratio of the chitosan solution is 1:1.05-1.2; the degradation temperature is 80-85°C, and the degradation time is 2-2.5h; after the degradation is completed, the pH value of the degraded chitosan solution is adjusted to 8.5-9 with NaOH solution, and then suction filtered and evaporated. water, vacuum-dried, by controlling different oxidative degradation reaction conditions such as H 2 o 2 Concentration, reaction temperature, reaction time, pH value, etc., can prepare chitosan with different molecular weights. h 2 o 2 The hig...

[0022] Effect of Chitosan Molecular Weight on Antibacterial Properties of Finished Down

[0023] Take 10kg of white duck down, after the dehydration process, use chitosan antibacterial finishing, test the effect of different molecular weight chitosan on the antibacterial rate of down. Other process conditions are: the degree of deacetylation of chitosan is 80.0%, the concentration of chitosan in the finishing solution is 20g / l; dipping for 10 minutes, one dipping and one rolling, the liquid rolling rate is 300%, 100 ° C opening and drying Dry.

[0025]

[0026] Note: Antibacterial performance is tested according to FZ / T 73023-2006

[0027] It can be seen from Table 1 that the molecular weight of chitosan has a great influence on the antibacterial properties of down. The smaller the molecular weight of chitosan, the better the antibacterial effect. This is bec...

[0030] Effect of deacetylation degree of chitosan on antibacterial properties of finished down

[0031] Take 10kg of white duck down, after the dehydration process, use chitosan for antibacterial finishing, and test the effect of chitosan with different degrees of deacetylation on the antibacterial rate of down. Other process conditions are: the molecular weight of chitosan is 1.5*10 4 , the concentration of chitosan in the finishing solution is 20g / l; dipping for 10min, one dipping and one rolling, the liquid rolling rate is 300%, and it is opened and dried at 100°C.

[0032] Table 2. The effect of chitosan with different degrees of deacetylation on the antibacterial properties of down

[0033]

[0034] It can be seen from Table 2 that the down treated with chitosan with different degrees of deacetylation has different antibacterial properties, and with the increase of the degree of deacetylation, the antibacterial properties of chitosan are significantly enhanced. Among...

Abstract

The invention discloses an arrangement method for down feathers with an antibacterial function. The arrangement method comprises the following steps of: dipping the down feathers for 10 minutes in a manner of dipping once and rolling once, wherein the mangle expression is 300 percent; and opening and drying at temperature of 100 DEG C until the down feathers are constant in weight. Compared with the prior art, the arrangement method has the advantages that: the combination degree of chitosan with the fibers arranged into down feather fibers is higher; the chitosan cannot be dissolved in neutral water and alkaline water easily; and therefore, even a down feather product is washed with water for times, the antibacterial performance is not reduced.

Description

technical field [0001] The invention belongs to a finishing method, in particular to a finishing method of down. Background technique [0002] Down raw materials contain a lot of stains and a variety of pathogenic microorganisms. If they are not properly sterilized during down processing, a large number of pathogenic sources will be carried in down products, endangering people's health; at the same time, down products will It is unavoidable to be affected by the hot and humid environment for a long time, and the probability of mildew will increase greatly, causing peculiar smell, and the health of users will be threatened. Therefore, the antibacterial and antibacterial function of developing down is very applicable and has great significance. [0003] The existing production process of antibacterial down includes the following processes: pre-separation process, ash removal process, fine separation process, washing process, dehydration process, finishing process, drying proc...
