Description
Technical field
The present invention relates to textile engineering technical field, more particularly to a kind of floride-free durable water repellent silk method of modifying.
Background technology
Silk is so that its is magnificent, glossiness is high and draping property is good etc. and turns into traditional high-grade fabric.But face
The keen competition of fiber product, silk product is single, lack of diversity and feature so that the part of silk on piece market
Volume drops to almost negligible stage.Therefore, it is necessary to develop differential silk, the more functions of silk are assigned, expand silk
Silk fabric application field.Silk water repellency is such as assigned, the self-cleaning property of silk can be improved, is not easy to soak.Water repellent silk can be used for taking
Fill and as ornament materials.
The water repellent finish weaved at present mainly uses fluorine-contained finishing agent, and the fabric that fluorine-contained finishing agent arranges has good refuse
Water refuses oily and antifouling function.But the fluorine-contained finishing agent due to mainly applying in the market is all difficult to degrade, carrying capacity of environment
Greatly, gradually it is eliminated and disables.Therefore, the new method for sorting of the floride-free durable water repellent silk of exploitation has important theoretical and real
Border meaning.
The content of the invention
It is an object of the invention to provide a kind of method of modifying of floride-free durable water repellent silk, the silk of arrangement is not fluorine-containing,
The silk of arrangement has good water repellency, and spray rating reaches 4 grades, and water contact angle reaches 150oMore than；Meanwhile with good
Good durability, 50 water repellencies of washing still keep good.
The present invention is achieved through the following technical solutions：
A kind of floride-free durable water repellent silk method of modifying, comprises the following steps：
1）Silk is put into after adding epoxychloropropane in dyeing pot, dyeing pot is placed in infrared high-temperature pressure dyeing machine,
99-103 DEG C of keeping temperature, rotating speed 35-45r/min, react 1-2h；
2）Take out silk, soap；
3）Silk after soaping is put into dyeing pot, is added octadecylamine emulsion, 45 DEG C of keeping temperature, is reacted 1-2h；
Silk Ag is added in step 1, adds epoxychloropropane 20Aml, the mass concentration of the octadecylamine emulsion added in step 3
For 1%-5%, the octadecylamine emulsion of addition and the weight ratio of epoxychloropropane are 1:1.
Preferred scheme：Epoxychloropropane 100-300ml is added in step 1.
The present invention principle be：At 100 DEG C or so, the epoxy radicals of epoxychloropropane can be with the amino on silk fibroin
Chemically reacted with hydroxyl, epoxychloropropane is grafted on the protein molecule of silk with covalent bond, assigns the silkworm of silk
Silk Protein Molecules chlorine atom group.Afterwards, octadecylamine chemically reacts with silk, and chlorine atom is substituted by octadecylamine, i.e., and ten eight
Amine is grafted on silk with covalent bond.Because octadecylamine has the hydrophobic hydrocarbon chain of 18 carbon, so, it is good to assign silk
Water repellency.
It is as follows that water repellent silk prepares chemical equation：
Compared to the prior art, the present invention has the following advantages
（1）Modified silk has good water repellency, and spray rating reaches 4 grades, and water droplet contact angle reaches 150oMore than；
（2）The water repellency of modified silk keeps good, and after washing 50 times, spray rating still reaches 4 grades, and water droplet contact angle still reaches
150oMore than.
