Abstract
The invention discloses a clothes fabric softening treatment process, which comprises the steps of firstly carrying out surface etching treatment on nano silicon dioxide to obtain porous nano silicon dioxide, then carrying out grafting modification on the porous nano silicon dioxide by using tannic acid, wherein the surface of tannic acid contains a large amount of hydroxyl groups, and grafting the tannic acid on the surface of the nano silicon dioxide, so that the dispersion performance of the nano silicon dioxide in resin is improved, the nano silicon dioxide has higher mechanical strength, and further the wear resistance of fabric fibers is improved; meanwhile, the added tannic acid can form a layer of hydrophilic adsorption film on the surface of the fabric fiber to play a role in wetting the surface of the fiber, so that the fabric fiber is endowed with good softness; the amino silane coupling agent is utilized to pretreat the fabric base cloth, under the action of the cross-linking agent polyethylene glycol diglycidyl ether, the amino groups on the surface of the pretreated fabric base cloth are subjected to chemical reaction with active groups in the finishing liquid, so that the fabric base cloth is firmly combined in a chemical bond mode, and is more washable and better in softening effect.
Description
Technical Field
The invention relates to the technical field of textile fabrics, in particular to a clothes fabric softening treatment process.
Background
When the fabric is in contact with human skin, the fabric is required to have good touch feeling, such as softness, fluffiness, skin adhesion and the like; therefore, the fabric needs to be subjected to soft finishing, and the conventional soft finishing is to padding the fabric with a softening agent, so that the soft effect of the softening agent on the fabric is achieved.
At present, the most common softening finishing agent is amino silicone oil softening agent, and as amino can interact with hydroxyl, carboxyl and the like on the surface of the fabric, siloxane can be directionally attached to the surface of the fabric, excellent hand feeling can be generated, and the friction coefficient between fabric fibers is reduced, so that a good softening finishing effect is achieved; however, the amino silicone oil has some problems in the use process, often has no self-dispersing property, and after being prepared into the amino silicone oil emulsion, the amino silicone oil is easy to generate the phenomena of oil drifting or roller sticking in the storage and use processes; meanwhile, the hydrophilicity of the fabric treated by the common amino silicone oil emulsion is reduced, so that the wearing comfort of the treated textile fabric is affected.
Chinese patent document CN201810363311.2 discloses a fabric softening finishing agent and a preparation method thereof, comprising the steps of: 3- [3- (2-H-benzotriazole-2-yl) -4-hydroxy-5-tert-butylphenyl ] -propionic acid-polyethylene glycol 300 ester is dissolved in an organic solvent to form a solution, epoxy silicone oil and a catalyst are added into the solution, the solution is stirred and reacted for 8-10 hours in a nitrogen or inert gas atmosphere at 70-80 ℃, the organic solvent is removed by rotary evaporation, and the fabric softening finishing agent is obtained.
