Method.
Background technology
Cellulosic fabric (cotton, fiber crops, viscose glue etc.) after concentrated alkali solution (NaOH, 240g/L) mercerising,
All there is great change in the molecule of cellulose fibre and macromolecular structure, the molecule changing cellulose fibre takes
To, crystalline texture, degree of crystallinity and form, thus enhance the sorption of fiber, tensile strength, extensibility
And gloss and rounding property, also have impact on final fabric or the feel of yarn and drapability simultaneously.After mercerising,
Alkali in fiber is fully removed, until fiber is neutrality.Organizine photoproduction lixiviating in puerperal technique is the feelings at tension force
Under condition, use suction device by hot diluted alkaline drip washing fabric;After loosening weft tension subsequently, enter lixiviating case, use
Light alkali cleaning is steamed, and the bath of last clear water is to neutral;Process is complicated and water consumption is big.During mercerising, NaO
H penetrates into molecule and the structure destroying cellulose in fiber.During lixiviating, because sodium ion divides at cellulose
Be combined in subchain and with cellulosic molecule, cause being difficult to eccysis.This be also need during mercerising lixiviating loaded down with trivial details
The reason of eccysis technique.Although liquefied ammonia has excellent Swelling Functions to cellulose fibre, but NaOH is at liquefied ammonia
In dissolubility the least, existing method is difficult by pure liquefied ammonia eccysis NaOH while texturized fiber cellulose fiber
Molecule.
Summary of the invention
It is an object of the invention to provide a kind of liquefied ammonia aqueous solution lixiviating method after mercerising process, solve mesh
During front tradition industrial mercerising lixiviating, water consumption is big and eccysis technique is loaded down with trivial details, be difficult by pure liquefied ammonia expanded
The problem of eccysis NaOH molecule while cellulose fibre.
The technical solution adopted in the present invention is to follow the steps below:
Step 1: fabric is dipped in NaOH solution under conditions of tension force process, and NaOH solution concentration is
230g/L-250g/L;
Step 2: control treatment temperature, at 17 DEG C-22 DEG C, processes 4-6 minute, and taking-up is extracted;
Step 3: wash 5-20 time at the liquefied ammonia aqueous wash medium that water content is 1%-12%, each 8-12 minute,
Reach lixiviating effect.
Further, in described step 1, NaOH solution concentration is 240g/L.
Further, in described step 2, treatment temperature is 20 DEG C, and the process time is 5 minutes.
Further, in described step 3, liquefied ammonia aqueous solution water content is 10%, and washing times is 10 times, every time
Wash 10 minutes.
The invention has the beneficial effects as follows in the ramee after can utilizing liquefied ammonia solution washing concentrated base mercerising
NaOH molecule.
