Problems solved by technology

[0005] However, it is not convenient to use existing testing techniques to demonstrate the distribution of sol particles inside the fiber
Theoretically speaking, use spectrometers for studying element distribution, such as X-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, Auger electron spectroscopy, scanning electron microscope + energy spectrometer, X-ray fluorescence spectroscopy, etc. Characterization of the distribution of silicon element can prove the distribution of sol particles in the fiber, but because the ray energy used by the instrument is too high or the spot size is much larger than the fiber diameter, the feasibility in practice is not optimistic

Embodiment 1

[0028] (1) Fabric dyeing

[0029] Dyeing prescription:

[0030] C.I. Acid Green 16 dye 30% o.w.f

[0031] Acetic acid adjust pH=5

[0032] Bath ratio 100:1

[0033] Dyeing equipment: Taiwan RAPID H-12F dyeing machine

[0034] Dyeing process: Keep dyeing at 40°C for 3min, heat up to 80°C at a rate of 2°C / minute, then heat up to 98°C at a rate of 1°C / minute, and keep it warm for 60 minutes. After dyeing at 95℃, soaping for 20min to remove floating color, then wash the fabric with water and dry at 120℃.

[0035] (2) Sol preparation and finishing

[0036] In a water bath, N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane (AEAPTMS) and water were mixed and stirred at a molar ratio of 1:20 for 30 minutes to prepare an amino sol.

[0037] In a water bath, γ-glycidoxypropyltrimethoxysilane (GPTMS) and water (pH 3.5) were mixed and stirred at a molar ratio of 1:35 for 30 minutes to prepare a non-amino sol.

[0038] Two pieces of dyed and dried wool fabrics were soaked in the sol for 10 minute...

Abstract

The invention relates to a method to identify the distribution of amino siloxane sol in fabric fiber. It includes the processes: (1) it uses the triarylmethane colouring matters to color, soap boil and dry the textile of fabric fiber; (2) the amino siloxane sol made by the amino siloxane, the organic solvent and water, which the mol ratio is 1:0-10:1-100; (3) By rolling or dipping, the sol is put on the textile and dried; (4) the textile after treating by sol is boiled and heated in stem; (5) the textile put under the optical microscope is observed the fiber surface color and prepared the fiber slice up to observe the inner color and determine the sol particle distribution condition. The method is simple and has low cost. The result is accuracy and has good repeatability.

Description

Technical field [0001] The invention belongs to the field of finishing textiles by sol-gel technology, and particularly relates to a method for identifying the distribution of aminosiloxane sol in textile fibers. Background technique [0002] In recent years, sol-gel technology has received extensive attention in the textile industry. This is because sol-gel technology provides new opportunities for the textile industry and will benefit it in the future. [0003] The preparation and application of sol-gel can be completed with conventional production equipment at room temperature and normal pressure, while nanosols prepared by sol-gel method based on organically modified siloxane and other metal alkoxides as raw materials can be used on the surface of textiles. A transparent porous film with good fixation is formed to realize the surface modification and functional finishing of textiles, such as color fixation, anti-ultraviolet, wool anti-felting, water and oil repellent, antibac...
