Abstract
The invention discloses an anti-crease finishing agent as well as a preparation method and a padding method thereof, belonging to the technical field of fabric anti-crease finishing. The anti-crease finishing agent is characterized by consisting of 55-65g / L glyoxal modified citric acid, 1.3-2.6g / L fatty alcohol-polyoxyethylene ether, 6-15g / L crosslinking agent and 24-37g / L catalyst. The preparation method comprises the following steps: enabling citric acid and glyoxal in a molar ratio of 1 to (5.4-6.6) to react for 5.7-6.5h at 38-43 DEG C to obtain glyoxal modified citric acid; and preparing the anti-crease finishing agent according to the dosage. The application comprises a step of padding the finishing liquid, a pre-baking step and a baking step, wherein the baking time is 2-3min; and the baking temperature in the baking step is 140-180 DEG C, and the baking time is 1-3min. The product avoids the problem of formaldehyde release and does not harm human health.
Description
technical field [0001] The anti-wrinkle finishing agent and its preparation and padding method belong to the technical field of fabric anti-wrinkle finishing. Background technique [0002] N-methylolamide resin is a kind of anti-wrinkle finishing agent commonly used in industry. It is used for anti-wrinkle finishing of cellulosefiber fabrics and can obtain good anti-wrinkle effect. Among them, 2D resin is the most widely used. The fabric finished with 2D resin has good durable pressing finishing effect. But there are following defects: [0003] 1. Formaldehyde will be released during use and storage, which will endanger people's health; [0004] 2. After finishing, the fabric will be seriously yellowed; [0005] 3. After finishing, the strength of the fabric is greatly reduced. [0006] In the traditional treatment process, citric acid is also often used as an anti-wrinkle finishing agent. Citric acid has the advantages of safety, non-toxicity and low cost. However, th...
