Abstract
The invention discloses a processing method of hydrophobic washable down. The processing method comprises three steps: firstly, microetching processing is carried out on down by utilizing pre-processing liquid, so that reactivity of protein fibers is improved; in the crosslinking modification process, glutaraldehyde is grafted with down fibers and nano-scaled silicon is introduced, so that the nano-scaled silicon can be firmly combined on the fibers; compared with a method which directly adds a nano material, the processing method is safer and more efficient; meanwhile, a porous structure of the nano-scaled silicon cannot influence warmth retention and air permeability properties of the down, but on the contrary, improves hydrophobicity of the down fibers, improves washing resistance, meanwhile, has excellent adsorption and reduces drift of the down. Compared with the prior art, the processing method disclosed by the invention is more efficient, is simple in production process, adopts healthy and environment-friendly raw materials, overcomes the defect that in the prior art, down is easy to drift after adsorbing water, and can be used for preparing lightweight warm down garments.
Description
Technical field
The present invention relates to down fiber processing technology field, particularly relate to the processing method of a kind of wash-durable hydrophobic 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 wash-durable hydrophobic eider down.
The present invention is achieved by the following technical solutions:
A kind of processing method of wash-durable hydrophobic 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 N, N '-dimethyl Methanamide: thiourea: the weight ratio of deionized water=0.5:1:80-120 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 adds appropriate ammonia after terminating, regulation solution ph is 8-9, drip tetraethyl orthosilicate subsequently, dripping limit ultrasonic agitation below 50-60 DEG C of condition, filter after placing 30-40min after completion of dropwise addition, filtrate is 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 volume ratio of tetraethyl orthosilicate.
The present invention carries out microetch process first with pretreatment liquid to eider down, increase the reactivity of azelon, glutaraldehyde and down fiber is utilized to be grafted and introduce nano-silicon in cross-linking modified processing procedure, nano-silicon can be firmly combined on fiber, safer efficiently than directly adding nano material, the structure of nano-silicon porous does not interferes with the heat-insulation breathable of eider down simultaneously, instead down fiber hydrophobicity is improved, improve washability ability, it is provided simultaneously with excellent adsorptivity, reduces flying away of eider down.Present invention process is the most highly efficient, and production technology is simple, raw material health environment-friendly, improves the defect that tradition eider down water suction is easily flown away, can prepare frivolous warming eider down dress ornament.
Detailed description of the invention
This embodiment uses duck down feathers to process, and processes step and is:
(1) pre-treatment: first carry out eider down washing, grease removal, be dried after remove impurity, subsequently eider down is processed 10h with pretreatment liquid according to the volume ratio mix and blend of 1:4, process is taken out after washing 3 times standby after terminating, wherein said pretreatment liquid is by N, N '-dimethyl Methanamide: thiourea: the weight ratio of deionized water=0.5:1:80 is formulated；
(2) cross-linking modified process: eider down step (1) obtained puts in the glutaraldehyde water solution that concentration is 2%, 1h is reacted under the conditions of 55 DEG C, reaction adds appropriate ammonia after terminating, regulation solution ph is 8, drip tetraethyl orthosilicate subsequently, dripping limit ultrasonic agitation below 50 DEG C of conditions, filter after placing 30min after completion of dropwise addition, filtrate is standby after heat treatment 1h under the conditions of 70 DEG C；
