Problems solved by technology

Even so, the pre-sizing treatment has exposed great disadvantages in the processing of silk inkjet printing: the use of thickeners in the slurry will fundamentally change the feel and resilience of silk fabrics that are known for their softness and comfort
At the same time, the use of alkali and urea will inevitably cause a lot of waste and pollution

Embodiment 1

[0033] The method that adopts plasma-chitosan technology of the present embodiment to improve the inkjet printing performance of antibacterial silk fabric comprises the following steps:

[0034] Preparation of S1 nano-chitosan

[0035] 10g of high molecular weight chitosan was added to 600ml of 2% acetic acid solution by mass, fully stirred at 80°C to dissolve it; 60ml of 3% by mass was added dropwise. 2 o 2 Solution, continue to react for 2h; bake after neutralizing the upper layer residue with distilled water; add 4ml ethanol to the lower layer solution, let stand for 24h to precipitate chitosan, obtain degraded low molecular weight chitosan after centrifugal drying. Reducing the molecular weight of chitosan can make it more permeable and antibacterial.

[0036] Under the conditions of a temperature of 20°C and a pH value of 3, after dissolving 0.25g of degraded low molecular weight chitosan, 0.5g of citric acid, 0.1g of Span-80 and 0.25g of TPP in 50ml of distilled water,...

Embodiment 2

[0083] The method that adopts plasma-chitosan technology of the present embodiment to improve the inkjet printing performance of antibacterial silk fabric comprises the following steps:

[0084] Preparation of S1 nano-chitosan

[0085]The high molecular weight chitosan of 9g is joined in the acetic acid solution of 2% by mass percent in 500ml, fully stirs it to dissolve at 60 ℃; 2 o 2 Solution, continue to react for 1.5h; bake after neutralizing the upper layer residue with distilled water; add 3.5ml ethanol to the lower layer solution, let stand for 23h to precipitate chitosan, and obtain degraded low molecular weight chitosan after centrifugal drying.

[0086] Under the conditions of temperature 21°C and pH value 2.5, after dissolving 0.1g of degraded low molecular weight chitosan, 0.1g of citric acid, 0.3g of Span-80 and 0.1g of TPP in 50ml of distilled water, use an ultrasonic disperser at 450w Disperse for 25 minutes to obtain nano-chitosan. After measurement, the part...

Embodiment 3

[0093] The method that adopts plasma-chitosan technology of the present embodiment to improve the inkjet printing performance of antibacterial silk fabric comprises the following steps:

[0094] Preparation of S1 nano-chitosan

[0095] The high molecular weight chitosan of 11g is joined in the acetic acid solution of 2% by mass percent in 700ml, fully stirs it to dissolve at 70 ℃; 2 o 2 Solution, continue to react for 2.5h; bake after neutralizing the upper layer residue with distilled water; add 4ml ethanol to the lower layer solution, let stand for 24h to precipitate chitosan, obtain degraded low molecular weight chitosan after centrifugal drying.

[0096] Under the conditions of temperature 20°C and pH value 3.5, after dissolving 0.2g of degraded low molecular weight chitosan, 0.3g of citric acid, 0.5g of Span-80 and 0.2g of TPP in 50ml of distilled water, use an ultrasonic disperser at 450w Disperse for 30 minutes to obtain nano-chitosan. After measurement, the particle...

Abstract

The invention discloses a method for improving inkjet printing performance of an antibacterial silk fabric by adopting a plasma-chitosan technology, and belongs to the technical field of silk fabrics. A pollution-free natural bio-based paint is prepared by combining nano chitosan with an air plasma pretreatment dispersion, and is used for improving the inkjet printing performance of the antibacterial silk fabric.

Description

technical field [0001] The invention relates to the technical field of silk fabrics, in particular to a method for improving the inkjet printing performance of antibacterial silk fabrics by adopting plasma-chitosan technology. Background technique [0002] Inkjet printing is more and more favored by consumers for its advantages of low energy consumption, no pollution, short cycle, and meeting individual needs. At the same time, both manufacturers and researchers are seeking and developing new inkjet printing methods. printing material. Among the frequently used natural textiles, silk has long been favored as a fabric for high-end clothing and bedding because of its light texture, elegant luster, strong heat resistance, good moisture absorption, and good air permeability. Reactive dyes have the characteristics of bright color, convenient use, complete chromatogram, and low price. Reactive dyes are the only type of reactive dyes that can be covalently bonded to silk fibers, a...
