Problems solved by technology

Although silk has high wearability and comfort, but because silk mainly becomes fibroin, silk processed from silk cannot be cleaned by machine washing, mainly because silk has poor wear resistance and cannot be washed in the machine. Or it is easy to produce hair balls during hand washing, which reduces the wearability and performance of silk textiles

Embodiment 1

[0023] A method for improving the abrasion resistance of silk with phenolic resin modified kraft glue, comprising the following steps:

[0024] (1) Modification: Take kraft glue and add 11 times its mass of deionized water to cook in boiling water for 26 minutes. After cooling, add compound enzyme agent for low-temperature enzymatic hydrolysis for 6.5 hours, and then add 1.5% galacturonic acid and mass of deionized water respectively. After mixing with 0.2% anka penicillin, stir and cook, then add urea and sodium thiosulfate to it respectively, transfer to the reaction kettle to evacuate to a vacuum, then fill it with nitrogen and let it stand for 3.5 hours, the pressure is 2.4Mpa, and use ultrasonic Oscillate at intervals of 21 minutes to obtain a treated kraft glue solution; then add 5.2% of its mass water-soluble phenolic resin and 0.32% nano-titanium dioxide powder to the treated kraft glue solution, stir and mix at a temperature of 78°C and a speed of 18100r / min for 28min,...

Embodiment 2

[0040] A method for improving the abrasion resistance of silk with phenolic resin modified kraft glue, comprising the following steps:

[0041] (1) Modification: Take kraft glue and add deionized water 13 times its mass to cook in boiling water for 29 minutes. After cooling, add compound enzyme agent for low-temperature enzymatic hydrolysis for 7.5 hours, and then add deionized water with 3.1% galacturonic acid and mass After mixing with 0.38% Anka penicillin, stir and cook, then add urea and sodium thiosulfate to it respectively, transfer to the reaction kettle to evacuate, then fill it with nitrogen and let it stand for reaction for 4 hours, the pressure is 4.0Mpa, and use ultrasonic interval Shake for 24 minutes to obtain a processed kraft glue solution; then add 6.7% of its mass water-soluble phenolic resin and 0.57% nano-titanium dioxide powder to the processed kraft glue solution, stir and mix at a temperature of 84°C and a speed of 20900r / min for 34min, and statically K...

Abstract

The invention discloses a method for improving silk wear resistance by phenolic resin modified oxhide gelatin. The method includes the steps: (1) dissolving the oxhide gelatin in water, cooking the oxhide gelatin, adding compound enzymes for enzymolysis, adding galacturonic acid, Anka penicillin, urea and sodium thiosulfate for treatment, adding water soluble phenolic resin and nano-titania powderand stirring and mixing the materials; (2) fumigating tedded silk by acetic acid solution and magnetized water, and then performing pressure cooking by gasoline; (3) performing surface treatment on the silk by surface treating agent solution, ammonia gas and ionized air; (4) performing poikilothermic treatment on the silk and then performing magnetization drying; (5) performing ionizing penetration and magnetizing penetration on the silk; (6) cleaning the silk by ethyl alcohol steam and then performing high-speed abrasive cleaning.

Description

technical field [0001] The invention belongs to the technical field of silk processing, and in particular relates to a method for improving the abrasion resistance of silk by modifying kraft glue with phenolic resin. Background technique [0002] Silk is a natural fiber formed by processing silkworm cocoons through cocoon cooking, silk reeling, reshaping and finishing. my country is the first country to use silk. According to historical records, ancient Chinese people began to use silk to make silk threads about 4,700 years ago. And weaving textiles, in the Shang and Zhou dynasties, the use of silk processing to make textiles such as silk, damask, and yarn; silk is rich in protein components, making the processed textiles soft, warm, non-irritating to the skin, and has Increased air permeability, portability and elastic effect can be used to process a variety of clothing fabrics and produce high-end garment products. The famous "Silk Road" in my country is a trade transaction ...
