Embodiment 1

[0023] The dry weight of 100g washed and chopped poultry feathers was dispersed in 1900g distilled water to prepare a suspension with a mass concentration of 5%, and then moved into a 5000mL three-necked flask equipped with a mechanical stirrer, a thermometer and a dropping funnel. Stir, heat up, and after the suspension reaches 70°C, add the reducing agent——NaHSO dropwise within 15 minutes 3 aqueous solution, where NaHSO 3 The dosage is 40% of the protein quality of feathers, the mass percentage of feathers in the whole suspension is 4%, keep stirring and reducing at 70°C for 4h, filter, wash with distilled water for 3 to 4 times, and dry the reduced feathers in an oven product;

[0024] The dry weight is that 100g feather product after reduction treatment is dispersed in 900g distilled water, is mixed with the suspension that mass concentration is 10%, then moves in the 2000mL three-neck flask that mechanical stirring, thermometer and dropping funnel are housed, stirs , he...

Embodiment 2

[0035] Adopt the method and step of embodiment 1, change the kind of acrylate monomer, change it into ethyl acrylate, the monomer molar ratio of ethyl acrylate and acrylic acid is 2:8, vinyl monomer (comprising acrylic acid monomer and acrylic acid Ethyl ester monomer) and the mass percent of feather protein powder are 46%, and all the other steps are identical with embodiment 1. See Table 3 for the water solubility and water-soluble stability of the feather protein-acrylic acid-ethyl acrylate graft copolymer slurry measured by visual observation method at pH=6.5, and the feather protein-acrylic acid-ethyl acrylate graft copolymer slurry measured by the roving method The adhesion performance of ester graft copolymer size to polyester fiber is shown in Table 4.

Embodiment 3

[0037] Adopt the method and step of embodiment 1, change the type of acrylate monomer, change it into butyl acrylate, the monomer molar ratio of butyl acrylate and acrylic acid is 2:8, vinyl monomer (comprising acrylic acid monomer and acrylic acid Butyl ester monomer) and the mass percent of feather protein powder are 52%, all the other steps are identical with embodiment 1. See table 3 for the water solubility and water-soluble stability of the feather protein-acrylic acid-butyl acrylate graft copolymer slurry measured by visual observation method at pH=6.5, and the feather protein-acrylic acid-butyl acrylate graft copolymer slurry measured by the roving method The adhesion performance of ester graft copolymer size to polyester fiber is shown in Table 4.

Abstract

The invention belongs to the technical field of modified protein sizing materials used for spinning warp sizing, and discloses a feather protein grafted copolymer sizing material and a preparation method thereof. The preparation method is characterized by after mixing a hydrophilic monomer-acrylic acid with a hydrophobic monomer-acrylate according to a certain molar ratio under the trigger action of a redox system, commonly grafting the hydrophilic monomer-acrylic acid with the hydrophobic monomer-acrylate to a molecular chain of protein extracted from poultry feathers which are subjected to reduction pretreatment, thus preparing a feather protein-acrylic acid-acrylate grafted copolymer sizing material which has good sizing performance on pure polyester and high-proportion polyester cotton blended yarn. According to the feather protein grafted copolymer sizing material prepared by the preparation method disclosed by the invention, the application field of a modified feather protein sizing material is expanded to synthetic fiber yarn sizing on the basis that the feather protein grafted copolymer sizing material is still enabled to be dissolved into water when in a neutral condition, and the limitation of a current feather protein sizing material is just suitable for natural fiber yarn sizing is broken.

Description

technical field [0001] The invention belongs to the technical field of modified protein size used in textile sizing, and in particular relates to a feather protein graft copolymer size and a preparation method thereof. Background technique [0002] Textile size is a necessary material in the production process of warp yarn sizing. The annual consumption in my country is about 300,000 tons, ranking second in the consumption of textile raw materials, second only to fiber materials. After the warp yarn is sized, it mainly relies on the adhesive in the size solution to improve the weavability of the warp yarn, reduce the end-break rate of the warp yarn, and ensure the smooth progress of the weaving process. Feather protein size is a new type of bio-based textile size. Its research and development history is relatively short, and it has only been more than three years until now. The practice of extracting protein from the feather by-products produced by the poultry processing in...
