Description

Technical Field

[0001] The invention belongs to the technical field of fabric finishing agents, and in particular relates to an anti-wrinkle and non-ironing finishing agent for cotton fabrics. Background Art

[0002] Cotton fabrics are increasingly favored by consumers because they are soft to the touch, breathable, highly absorbent, and comfortable to wear. However, they also have the disadvantages of poor wrinkle resistance, easy wrinkling, easy shrinkage, and the need for ironing after washing. In order to overcome these disadvantages, a wrinkle-free finishing agent is usually added to solve them. However, the wrinkle-free finishing method currently used in industry is to use a resin finishing agent to finish the fabric, but the production cost is high, and formaldehyde is easily released during wearing and use, and the strength is seriously damaged, the yellowing is serious, and the strength loss is large. Therefore, it is urgent to develop a safe, non-toxic, and environmentally friendly wrinkle-free finishing agent suitable for pure cotton fabrics. Summary of the invention

[0009] a and b are any integers from 4 to 20, c is any integer from 10 to 50, and n is any integer from 10 to 60.

[0010] Preferably, the anti-wrinkle and non-ironing finishing agent for cotton fabrics provided by the present invention also has the following technical characteristics: the carboxylic acid finishing agent comprises the following substances in parts by weight: 20-25 parts of 4-(acetoxy)benzoic acid, 10-18 parts of 1,3,5-cyclohexanetricarboxylic acid, and 9-15 parts of dimethylethylenetriaminetetracarboxylic acid.

[0011] Preferably, the anti-wrinkle and non-ironing finishing agent for cotton fabrics provided by the present invention also has the following technical features: the molecular formula of the organosilicon cross-linking agent is HO(CH 2 ) P1 NH(CH 2 ) P2 (CH 2 ) P3 SiC 3 (OCH 3 ) 2 , where P1=1-10, P2=2-8, P3=1-10.

[0012] Preferably, the anti-wrinkle and non-ironing finishing agent for cotton fabrics provided by the present invention also has the following technical features: the dispersant includes ammonium citrate and triethanolamine.

[0013] Preferably, the anti-wrinkle and non-ironing finishing agent for cotton fabrics provided by the present invention also has the following technical characteristics: the fiber protective agent includes polyethylene, water-based polyurethane and urea, and the weight ratio between the three is 3:2:1.

[0014] Preferably, the anti-wrinkle and non-ironing finishing agent for cotton fabrics provided by the present invention also has the following technical characteristics: the antibacterial agent is a quaternary ammonium salt or guanidine salt antibacterial agent.

[0015] The second aspect of the present invention provides a method for preparing the above-mentioned anti-wrinkle and non-ironing finishing agent for cotton fabrics, which has the following technical features:

[0016] (1) Add deionized water into a water phase pot and heat it to 30-50° C.; add a hydrophilic silicone finishing agent, a bactericide, a carboxylic acid finishing agent, and a fiber protective agent into the water phase pot and stir until they are completely dissolved to form a water phase;

[0017] (2) adding the organosilicon crosslinking agent and the organic acid into the oil phase pot, stirring for 30 to 60 minutes at a speed of 30 to 40 rpm and heating to 50 to 60° C. to form an oil phase;

[0018] (3) adding the melted oil phase into the water phase and adding a dispersant, and continuing stirring for 30 to 40 minutes. Cooling to room temperature to obtain the anti-wrinkle and non-ironing finishing agent for cotton fabrics.

[0019] Due to the adoption of the above technical solution, the present invention has the following advantages and beneficial effects:

[0020] Firstly, since a carboxylic acid finishing agent is added to the finishing agent of the present invention, the cotton fabric treated with the finishing agent of the present invention has a better anti-wrinkle effect, high wrinkle resilience, and small strength loss; it can significantly overcome the defects of existing cotton fabrics such as poor wrinkle resistance, easy wrinkling, easy shrinkage, and the need for ironing after washing.

[0021] Secondly, the wrinkle-resistant and non-ironing finishing agent of the present invention is easy to apply, and the shirt fabric can be treated by traditional methods such as dipping, spraying, and roller coating. After the wrinkle-resistant and non-ironing finishing agent of the present invention is used to perform non-ironing finishing on the shirt fabric, not only the non-ironing finishing of the fabric is achieved, but also the physical properties of the fabric such as whiteness, strength, and hand feel are guaranteed. At the same time, since the finishing liquid does not contain formaldehyde, the safety and environmental protection of the finished fabric are ensured.

[0022] Third, because the special antibacterial agent can make the polymer positively charged, it is easy to be adsorbed by various negatively charged bacteria and viruses, thereby inhibiting the division function of bacteria and viruses and making them lose their reproduction ability. In this way, the odor caused by bacterial reproduction is inhibited and the smell of clothes is kept fresh. DETAILED DESCRIPTION
