preparation example Construction

[0075] In the preparation step of the water and oil repellent finishing liquid, the raw materials including the water and oil repellent agent, the crosslinking agent, the organic solvent and acetic acid are mixed to obtain the water and oil repellent finishing liquid. The concentration of water and oil repellent in the water and oil repellent finishing liquid is 100~150g / L, the concentration of crosslinking agent is 10~25g / L, the concentration of organic solvent is 3~8g / L, and the concentration of acetic acid is 0.2~2g / L .

[0076] The water and oil repellent agent of the present invention can be prepared by the following steps: (1) pre-emulsification step; (2) intermediate reaction step; (3) final reaction step.

[0077] In step (1), perfluoroalkyl ethyl (meth) acrylate, C15-C25 alkyl (meth) acrylate, (meth) acrylate containing isocyanate, molecular weight regulator, iso Alcohol polyoxyethylene ether, C6-C25 alkyl polyoxyethylene ether, propylene glycol condensate and water ...

Abstract

The invention discloses an acrylic chloride fiber textile and a production method thereof. The acrylic chlorine fiber textile is finished with water and oil repellent finishing solution; the water and oil repellent finishing solution contains water and oil repellent agent, crosslinking agent, organic solvent and acetic acid; water and oil repellent agent is a random copolymer formed by copolymerization reaction Emulsion, raw materials for copolymerization include 20-40 parts of perfluoroalkyl ethyl (meth)acrylate, 10-25 parts of C15-C25 alkyl (meth)acrylate, 5-15 parts of isocyanate-containing ( Meth) acrylate, 2-4 parts of molecular weight regulator, 5-15 parts of vinyl chloride, 2-5 parts of isomeric alcohol polyoxyethylene ether, 1-3 parts of C6-C25 alkyl polyoxyethylene ether, 3-8 parts Parts of propylene glycol condensate, 0.5-2 parts of initiator and 20-45 parts of water. The water and oil repellency of the acrylic chloride fiber textile of the invention is improved.

Description

technical field [0001] The invention relates to an acrylic chloride fiber textile and a production method thereof. Background technique [0002] Acrylic textiles are formed from acrylic fibers or blended with acrylic fibers and other fibers. Acrylic chlorine fiber textiles have excellent flame retardant properties and natural soft feel, and are widely used in home textiles, protective clothing fabrics and decorative textile materials. Acrylic chlorine fiber textiles are used as protective clothing fabrics in toxic and harmful environments, which can prevent toxic and harmful gases from entering the human body through the skin. Acrylic textiles without a water and oil repellent finish have limited protective properties. In order to improve the protective performance of acrylic chloride textiles used in anti-virus clothing, water and oil repellent finishing agents are usually used for treatment. [0003] After finishing with the water and oil repellent agent, the water and ...
