Abstract
The invention discloses a treatment method of long-acting flame retardant down. The method comprises three steps, wherein the down is pretreated by pretreatment liquid containing ammonium polyphosphate first so as to improve the surface properties of fiber, enhance the reaction activity and realize certain flame-retardant effect of fiber; in a crosslinking modifying treatment process, glutaraldehyde is adopted for grafting treatment, and carboxylated nano expanded vermiculite micropowder is deposited and grafted to the fiber, thus, the advantages of the expanded vermiculite are introduced into the down fiber, a better flame-retardant fireproof effect of the fiber is obtained, and the porous structure of the expanded vermiculite does not influence the specific high warming property and air-moisture permeability of the down; and the modified down fiber is further treated by aftertreatment liquid to finally obtain novel down with long-acting flame retardance and loose and warming properties, and the use value of the down is effectively promoted.
Description
Technical field
The present invention relates to down fiber processing technology field, particularly relate to the processing method of a kind of long-acting fire-retardant eider down.
Background technology
Down fiber is a kind of natural animal protein fibre, and its lightweight is bulk, air-moisture-permeable, and warming effect is splendid, is commonly used for eider down dress ornament and goods.In process of production, eiderdown raw material needs to use as inserts after a series of process, eider down woollen will through over cleaning, grease removal, deodorization, sterilize, the program such as drying, if pretreatment process is mishandling, it will directly affect the using effect of eider down.
Owing to eider down belongs to animal matter series products, itself have inflammable, easily damage by worms, easy cooperating microorganisms, added value of product are low, maintenance and washing require the shortcomings such as high, if eider down can be applied some process means, maximize favourable factors and minimize unfavourable ones, it will widen the range of down products greatly.That reports at present carries out the processing methods such as fire-retardant, antibacterial to eider down, is the most directly mixed with inorganic agent by eider down and carries out the process of simple surface, and after so processing, the effect of product is held time short, along with washing process performance can gradually lose efficacy." down fiber fire resistance after glutaraldehyde grafting dicyanodiamine processes " literary composition carries out fire-retardant graft modification process to down fiber, although improve the fire-retardant timeliness of eider down to a certain extent, but the dicyanodiamine of grafting has certain toxicity, directly contact skin has harm, and actual application value is on the low side.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that the processing method of a kind of long-acting fire-retardant eider down.
The present invention is achieved by the following technical solutions:
A kind of processing method of long-acting fire-retardant eider down, described processing method comprises the following steps:
(1) pre-treatment: first carry out eider down washing, grease removal, be dried after remove impurity, subsequently eider down is processed 10-15h with pretreatment liquid according to the volume ratio mix and blend of 1:4-5, process is taken out after washing 3-5 time standby after terminating, wherein said pretreatment liquid is by thiourea: APP: the weight ratio of deionized water=0.5:5:80-120 is formulated；
(2) cross-linking modified process: eider down step (1) obtained puts in the glutaraldehyde water solution that concentration is 2-5%, 1-1.5h is reacted under the conditions of 55-60 DEG C, reaction is filtered after terminating, with backward filtrate is sprayed carboxylated nanometer expanded vermiculite solution, carry out under the conditions of being sprayed at 60-65 DEG C, sprayed after standby after heat treatment 1-2h under the conditions of 70-80 DEG C；
(3) post processing: the product of step (2) is put into after 1.5-2h is soaked in stirring in aftertreatment fluid and takes out, cleaning 3-5 post-drying with deionized water and i.e. obtain described eider down finished product, wherein said aftertreatment fluid is that polyquaternary ammonium salt-6, ethanol, deionized water form according to the proportions of 1-1.5:20-40:100-150.
In described step (2), eider down, the volume ratio of glutaraldehyde water solution are 1:2-3, and glutaraldehyde water solution is 1:0.01-0.02 with the weight ratio of carboxylated nanometer expanded vermiculite solution.
The compound method of described carboxylated nanometer expanded vermiculite solution is: take the expanded vermiculite of 10 weight portions and the dehydrated alcohol mixed grinding dispersion 2-3h of 20-30 weight portion, it is subsequently added the maleic anhydride of 1 weight portion, the Silane coupling agent KH550 of 1 weight portion, the sodium lauryl sulphate of 0.01 weight portion and the deionized water of 40-50 weight portion, under the conditions of 50-60 DEG C, high-speed stirred mixing 6-8h, to obtain final product.
The present invention carries out pretreatment first with the pretreatment liquid containing APP to eider down, it is possible not only to improve the surface property of fiber, improve reactivity, also impart the flame retardant effect that fiber is certain, grafting process is carried out first with glutaraldehyde in cross-linking modified processing procedure, again carboxylated nanometer expanded vermiculite micropowder deposition is grafted on fiber, the advantage of expanded vermiculite is introduced in down fiber, fiber is made to obtain the most excellent fire retardant effect, and the structure of expanded vermiculite porous does not interferes with, and the distinctive height of eider down itself is warming and breathable moisture permeability, the most post-treated liquid of modified down fiber processes further, finally give long-acting fire-retardant, the novel eider down of fluffy insulation, the effective use value promoting eider down.
Detailed description of the invention
This embodiment uses duck down feathers to process, and processes step and is:
