Problems solved by technology

The main anti-wrinkle finishing agent on the market is 2D resin, which has a good DP grade for cotton fabrics, but the problem of formaldehyde release has been threatening human health
However, the main disadvantage of FAP is that it has poor directness to fibers, and it is only suitable for pad dyeing and printing when used as a fixing agent; at the same time, it has poor water solubility, especially difficult to dissolve under low temperature conditions.

Embodiment 1

[0026] In a 1L three-necked flask, add 40g of ethylenediamine, 90g of sodium hydroxide, 200g of water, and 600mL of acetonitrile, and mechanically stir in an ice bath. After the temperature dropped below 5°C, 132.6 g of acryloyl chloride was added dropwise within 1 hour. After the dropwise addition, the ice bath was removed, and the solution was reacted at room temperature for 5 h. Then, acetonitrile was removed by distillation under reduced pressure, and the product was extracted from the aqueous solution with 400 mL of chloroform, and dried by adding magnesium sulfate overnight. After filtering magnesium sulfate, chloroform was distilled off again under reduced pressure to obtain the final product.

[0027] The structural formula is n=2.

[0028] The above product is formulated into 100g of anti-wrinkle finishing solution, the finishing agent is 7% of the quality of the finishing solution, sodium hydroxide is 5% of the quality of the finishing solution, Pingping plus O i...

Embodiment 2

[0030] In a 1L three-necked flask, add 222g of 1,8-diamino-3,6-dioxahexane, 90g of sodium hydroxide, 200g of water, and 500mL of isopropanol, and mechanically stir in an ice bath. After the temperature dropped below 5°C, 132.6 g of acryloyl chloride was added dropwise within 1 hour. After the dropwise addition, the ice bath was removed, and the solution was reacted at room temperature for 5 h. Then, the isopropanol was removed by distillation under reduced pressure, and the product was extracted from the aqueous solution with 400 mL of ethyl acetate, and dried by adding magnesium sulfate overnight. After filtering the magnesium sulfate, the ethyl acetate was distilled off again under reduced pressure to obtain the final product.

Abstract

The invention relates to anti-crease finishing agent for acrylamido cotton fabric, and a preparation method and application thereof. The anti-crease finishing agent is structurally characterized in that a molecule comprises two or more acrylamido, and is formed by performing a series of processes to compound containing two or more amino or imido and acryloyl chloride. The anti-crease finishing agent has a good anti-crease effect on cotton fabric, and by forming finishing liquor with alkaline agent, softening agent and surfactant to perform anti-crease finishing to cotton fabric, the anti-crease finishing agent can ensure that the creasy recovery angle is increased to more than 220 degrees from 150 to 155 degrees and the breaking strength is more than 85 percent. The anti-crease finishing agent can not produce formaldehyde, can perform crosslinking with cellulosic fiber through low temperature, and is convenient to synthesize and apply, and has a broad application prospect.

Description

technical field [0001] The invention belongs to the field of anti-wrinkle finishing agents for cotton fabrics, in particular to an acrylamide-based anti-wrinkle finishing agent for cotton fabrics and its preparation method and application. Background technique [0002] Cotton fabric is favored by people because it is comfortable to wear and has good hygroscopicity, but it is easy to wrinkle and difficult to care for, which brings inconvenience to production and use, and cannot meet people's needs. Therefore, anti-wrinkle finishing of cotton fabric is an indispensable functional finishing to promote social development. The main reason for the wrinkling of cotton fabrics is that the hydroxyl groups on the cellulose molecular chains in the amorphous region of cotton fibers can slip under the action of external force, and form hydrogen bonds in new positions to prevent the molecular chains from returning to their original state. At present, the anti-wrinkle effect is mostly ach...
