1, the preparation method of suction color fibre provided by the invention and suction look non-weaving cloth, the cation cellulose ether aqueous solution of the preparation method of this suction color fibre to be configuration concentration be 5g/L-100g/L, the described cation cellulose ether aqueous solution is regulated to be alkaline environment, and viscose is put into the described cation cellulose ether aqueous solution, take out after 80 DEG C ~ 100 DEG C reactions, dry, obtain described suction color fibre, compared with prior art, described cation cellulose ether can be adsorbed on the surface of described viscose, under the alkaline environment of high temperature, the described cation cellulose ether reaction being adsorbed on described viscose surface generates poly-quaternary ammonium salt class adsorption group, described poly-quaternary ammonium salt class adsorption group is firm, graft on the surface of described viscose equably, thus ensure that described suction color fibre is to the adsorption capacity of dyestuff.
2, the preparation method of suction color fibre provided by the invention and suction look non-weaving cloth, the preparation method of this suction look non-weaving cloth first provides described suction color fibre, then, by the lapping of described suction color fibre, finally, described suction color fibre fixed network after lapping is become cloth, formed and inhale look non-weaving cloth, because described suction color fibre itself has adsorption capacity, so do not need at fixed network Cheng Buhou grafting adsorption group, the described suction look non-weaving cloth intensity formed is high, not yielding, surface clean, and high adsorption capacity, can repeatedly use.
3, the preparation method of suction color fibre provided by the invention and suction look non-weaving cloth, described provide the step of described suction color fibre and described by the step of described suction color fibre lapping between, finish is added to described suction color fibre, to improve the carding property of described suction color fibre, avoid the knotting of described suction color fibre and combing bad, make the described suction look nonwoven fabric surface that obtains cleaner, smooth, and improve tear resistance further.
4, the preparation method of suction color fibre provided by the invention and suction look non-weaving cloth, described provide the step of described suction color fibre and described by the step of described suction color fibre lapping between, the polyester staple fiber being less than or equal to 40% is added to described suction color fibre, the intensity of described polyester staple fiber is high, can improve the tear resistance of described suction look non-weaving cloth further.
5, the preparation method of suction color fibre provided by the invention and suction look non-weaving cloth, described provide the step of described suction color fibre and described by the step of described suction color fibre lapping between, the thermal shrinkage fiber being less than or equal to 15% is added to described suction color fibre, and, described described suction color fibre fixed network after lapping is become cloth step after, carrying out a hot pressing makes described thermal shrinkage fiber solidify, thus increases the intensity of described suction look non-weaving cloth further.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
