Description
Technical field
The present invention relates to fabric post-treatment field, and in particular to a kind of method for sorting of knitted fabric anti-fluffing and anti-pilling.
Background technology
The wearability that fabric pilling degree influences fabric is to influence the important indicator of textile product quality.Knitted fabric
Species it is a lot, but they also possess the drawbacks of common, easy pilling.Such as：Pure cotton knitted fabric has excellent relax
Adaptive and elasticity, but its twist is low, fiber ends and fine hair easily float on fabric face, rubbed to tangle into difficult for drop-off small
Ball, the outward appearance and feel for causing fabric are affected.Wool fabric due to reasons such as its fibre structure, fabric structures,
During processing, dress and washing, the effect such as constantly it is subjected to rubbing, rub and bend, easily generation pilling phenomenon,
Influence its attractive in appearance and wearability；Meanwhile the scale structure of wool the main reason for being wool fabric pilling, but it is most of
Handling process the drawbacks of certain all be present.Generally, the scale layer of wool can be destroyed using subtraction process, to the strong of wool fiber
Power is caused compared with macrolesion, the shortcomings of easy yellowing of fabric and impaired strength be present；Using addition process inorganic agent can be made to cover wool
Fiber, the fabric feeling after arrangement is poor, and anti-fluffing and anti-pilling performance is not lasting.At present, most of anti-pilling finishing agents are deposited
The problem of more in finishing agent dosage, and baking temperature is high, applied to after-finishing of textile products, the feel of fabric can be made stiff, it is fine
Dimension damage is serious, destroys the original elasticity of knitted fabric and soft feel；And the anti-pilling finishing agent of different fabrics
Kind and method for sorting also differ, it is worse for the knitted fabric of blending, its applicability.
The content of the invention
Technical problems to be solved：It is an object of the invention to provide a kind of method for sorting of knitted fabric anti-fluffing and anti-pilling, fits
With the anti-pilling finishing of a variety of knitted fabrics, and the effect with good anti-fluffing and anti-pilling.
Technical scheme：A kind of method for sorting of knitted fabric anti-fluffing and anti-pilling, comprises the following steps：
（1）By polyester diol and polyether-tribasic alcohol, heating is evacuated to the small organic molecule and moisture removed in raw material,
105-118 DEG C of addition dimethylolpropionic acid of temperature, stirs to dimethylolpropionic acid and dissolves, different Buddhist is added after being cooled to 50-60 DEG C
That ketone diisocyanate and hydroxy-ethyl acrylate, continue to react 3-4 h, add triethylamine, react 20 min, finally, slowly
Ethylenediamine solution is added dropwise, is 50-55 DEG C in temperature, continues to stir 10-25 min, obtains aqueous polyurethane solution；
（2）Azodiisobutyronitrile, butyl acrylate, methyl methacrylate and epoxy resin are dissolved in trichloroethanes, stirred
After uniformly, polyethylene glycol is added, 3- diethyl amino propylamines is then added, is warming up to 60-70 DEG C, stirs, obtained wall material is
Epoxy resin, the microcapsules that core is the dichloroethanes containing azodiisobutyronitrile, butyl acrylate and methyl methacrylate
Solution；
（3）Aqueous polyurethane solution is heated to 70-80 DEG C, then knitted fabric is impregnated in aqueous polyurethane solution, is dried,
Step is impregnated in again（2）In the microcapsule solution of preparation, then through roll roll compacting, drying.
Further, the method for sorting of described a kind of knitted fabric anti-fluffing and anti-pilling, the step（1）It is middle by polyester binary
Alcohol and polyether-tribasic alcohol are heated to 100-120 DEG C, are 1.01 × 10 in vacuum32.5-4h is handled under conditions of Pa.
Further, the method for sorting of described a kind of knitted fabric anti-fluffing and anti-pilling, the step（2）Middle polyethylene glycol is
Polyethylene glycol 200 or polyethylene glycol 400.
Further, the method for sorting of described a kind of knitted fabric anti-fluffing and anti-pilling, the step（3）Roll roll compacting is rolled
Remaining rate 70-85%.
Further, the method for sorting of described a kind of knitted fabric anti-fluffing and anti-pilling, the step（3）Middle drying is divided into two
Individual step, prior to 60 DEG C drying 3-5min, 2-4 min are baked then at 80-130 DEG C.
Beneficial effect：The fabric anti-fluffing anti-pilling performance that method for sorting of the present invention arranges has lifting, can averagely be lifted
1-2 levels, while the fabric arranged by this method for sorting its feel will not damage, and have necessarily compared to unfinished fabric
Lifting.This is due in the method for sorting of the present invention, and aqueous polyurethane solution first is covered in into fabric face, then by micro- glue
After capsule emulsion is put on fabric, then through roll roll compacting, making microcapsules rupture, the core material solution of microcapsules can penetrate into fabric,
So that the material in core reacts with aqueous polyurethane, fabric is achieved with good anti-fluffing and anti-pilling performance.
