Embodiment 1

[0019] Take plant Stemona sessilifolia (Miq., Latin name Stemona sessilifolia (Miq.) Miq., Stemona sessilifolia, Stemona genus), wash and dry, then crush it into particles with a diameter of ≤5mm with a pulverizer, and then extract its anti-moth components with distilled aqueous solution, The mass ratio of basilicum to distilled aqueous solution is 1:20, the extraction temperature is 90°C, and the extraction time is 90 minutes to obtain an extract with anti-moth components; place the obtained extract in a centrifuge at 30,000r / min, and centrifuge Impurities are removed to obtain a refined liquid; through evaporation, the refined liquid is concentrated into a moth-proofing agent of 150% by mass (mass percentage of phytomega and water).

Embodiment 2

[0021] Prepare an aqueous sodium carbonate solution with a pH value of 8, put it into a cashmere sweater, the mass ratio of the cashmere sweater to the aqueous sodium carbonate solution is 1:20, raise the temperature to 80°C at a heating rate of 1°C / min, and keep it at this temperature for 15min, then Washing to neutrality; the aqueous solution of cashmere sweater, the anticorrosion agent of plant and the aluminum sulfate of 1% (o.w.f.) that cashmere sweater, embodiment 1 make are mixed, and the dry weight of anticorrosion contained in the aqueous solution of anticorrosion of plant and The mass percentage of cashmere products is 150%, adjust the bath ratio with water to 1:15, adjust the pH value of the solution to 4 with acetic acid, raise the temperature from room temperature to 40°C, and start to heat up at a rate of 1°C / min at 40°C to 80°C, and keep it at this temperature for 40 minutes, then lower the temperature to 60°C, wash with 0.5% (o.w.f.) 105 neutral soaping agent fo...

Embodiment 3

[0023] The sodium carbonate aqueous solution that preparation pH value is 8, puts into cashmere blanket, the mass ratio of cashmere blanket and sodium carbonate aqueous solution is 1: 30, is warming up to 90 ℃ with the heating rate of 1 ℃ / min, and at this temperature insulation 20min, then Washing to neutrality; The aqueous solution of cashmere blanket, the anticorrosion agent for plant stems made by embodiment 1 and the aluminum sulfate of 2% (o.w.f.) are mixed, and the dry weight of the stem fractions contained in the aqueous solution of anticorrosion for plant species is the same as The mass percentage of cashmere products is 150%, adjust the bath ratio with water to 1:30, adjust the pH value of the solution to 5 with sodium carbonate, and heat up from room temperature to 40°C. At 40°C, start with a heating rate of 1°C / min Raise the temperature to 90°C, keep it at this temperature for 50 minutes, then cool down to 60°C, wash with 0.5% (o.w.f.) 105 neutral soaping agent for 2...

Abstract

The invention relates to an application method of a plant stemona mothproofing agent on wool products. The method is characterized by comprising the following specific steps of: carrying out pretreatment on the wool products; mixing the wool products after treatment, a plant stemona mothproofing agent aqueous solution and 1-5% of aluminum sulfate, adjusting the bath ratio to be 1: (15-60) with water, adjusting the pH value of the solution to be 4-7 with acetic acid or sodium carbonate, raising the temperature to 40 DEG C from room temperature, raising the temperature to 80-100 DEG C at a heating rate of 1-3 DEG C per minute when at the temperature of 40 DEG C, preserving the temperature for 40-80 minutes, then reducing the temperature to 60 DEG C, washing for 15-45 minutes with 0.5% of 105 neutral soaping agent, and finally rinsing till purification with clear water and drying to obtain mothproofing wool products. The wool products after treatment are good in mothproofing effect, and the mothproofing indexes thereof achieve 1A level and are qualified through the detection of national quality supervision and inspection center (Shanghai) of wool textile products.

Description

technical field [0001] The invention relates to the application of a plant mothproofing agent on cashmere products, and belongs to the field of development and application of plant materials. Background technique [0002] As a kind of "soft gold", cashmere is loved by consumers because of its noble style and good performance. With the improvement of people's living standards, cashmere products have gradually become a popular product, and the market demand is increasing. Cashmere fiber is a kind of natural protein fiber, which is easily eaten by moths, which affects the quality and use value of cashmere products. Anti-moth processing plays a vital role in improving its quality and expanding its application range. [0003] The anti-moth function of cashmere products needs to be dyed and finished with the help of some functional anti-moth agents. Most of the functional anti-moth agents used today are derived from petroleum and coal tar products, which are mainly produced by ch...
