Problems solved by technology

However, the existing methods for surface treatment of fiber materials adopt the method of adsorption on the surface of the wrapping. The main disadvantages are that the combination between the wrapping and the fiber material is not firm, it is not resistant to washing, the number of washings increases, and the surface modified materials are easy to wash. fall off and lose its excellent properties

Embodiment 1

[0015] Prepare a solution according to the ratio of 0.5ml of TEOS, 2.5ml of OP emulsifier, and 47ml of distilled water. Soak 0.75g of pretreated wool in the above solution at room temperature for 30 minutes, so that the precursor is fully and evenly adsorbed on the surface of the wool. Use hydrochloric acid as the value regulator to adjust the pH value of the solution within the range of 2; put it into a constant temperature water bath, the reaction temperature is 30 ° C, and the reaction time is 5 hours, so that the reaction is carried out in wool, so that SiO 2 It grows directly on the surface of the wool; the above-mentioned surface nano-treated wool is added with a softener and then put into an oven, kept at 60°C for 3 hours, and then dried. It is about 20nm.

Embodiment 2

[0017] Prepare a solution according to the ratio of TEOS 2.5ml, OP emulsifier 10ml, and distilled water 37.5ml. Put 2.5g of pretreated wool in the above solution and soak it at room temperature for 60 minutes to make the precursor fully and evenly adsorbed on the wool surface. Use oxalic acid as the value regulator, adjust the pH value of the solution within the range of 5, put it in a constant temperature water bath, the reaction temperature is 95 ° C, and the reaction time is 1 hour, so that the reaction is carried out on the wool surface, and the SiO 2 It grows directly on the surface of wool, adds softener to the above-mentioned surface nano-treated wool, puts it in an oven, heats it at 120°C for 1.5 hours, and performs drying treatment. A layer of nano-film is evenly grown on the surface of wool. The thickness is about 100nm.

Embodiment 3

[0019] According to TEOS 1.5ml, OP emulsifier 5ml, distilled water H 2 The ratio of O 43.5ml is prepared solution, and the wool 1.5g after the pretreatment is soaked in above-mentioned solution at room temperature for 45 minutes, makes the precursor fully and evenly adsorbed on the wool surface, and the pH regulator uses hydrochloric acid to adjust the pH value of the solution In the range of 3.5, put it in a constant temperature water bath, the reaction temperature is 65°C, and the reaction time is 2 hours, so that the reaction is carried out on the surface of the wool, and the SiO 2 Directly grow on the surface of the wool, add the softener to the above-mentioned surface nano-treated wool, put it in an oven, keep it warm at 80°C for 2 hours, and perform drying treatment to uniformly grow a layer of nano-film on the surface of the fiber material. The film thickness is about 55 nm.

Abstract

The nano fiber material surface treating process includes compounding solution as coating material precursor, soaking the fiber material to be treated inside the solution for adsorbing the precursor homogeneously, regulating pH value, setting in constant temperature water bath to form 20-100 nm thick film coating the fiber, softening treatment and stoving. The SEM analysis shows that the surface nano layer is homogeneous and has good coating effect, the treated fiber has strength, hand feeling and brightness superior to the un-treated fiber. The treated fiber has far infrared function, antibiotic function, anti-ultraviolet function, etc. depending on the coated matter.

Description

technical field [0001] The invention relates to a method for surface treatment of fiber materials, in particular to a method for surface nanometerization treatment of fiber materials. Background technique [0002] Textile industry fiber materials, such as wool, cotton and various chemical fibers. Apply nanotechnology to its surface treatment to make it functional textile products, such as waterproof, anti-fouling, moisture-permeable environmental protection clothing, health care clothing that emits far-infrared rays, and anti-ultraviolet, anti-bacterial, negative ions, wave-absorbing, anti-static , photocatalysis, etc., the existing methods for surface treatment of fiber materials are: surface coating polymerization method, the purpose of which is to obtain a single stable sorbent, the method is to wrap polymer on the surface of fiber materials; surface modification is to The performance of the surface of fiber materials is changed, so that the gloss, feel and strength of t...
