Description

Technical Field

[0001] The invention relates to the technical field of textile auxiliary agent production, and in particular to an antistatic and anti-pilling softener for fabrics and a preparation process thereof. Background Art

[0002] Fabric softener is a washing and care product. It is suitable for use with detergents in the process of fabric washing and care to make fabrics soft, fluffy and eliminate static electricity. The function of fabric softener is like a protective film evenly applied to the surface of fabric fibers. As the softener is adsorbed on the fiber surface, the friction coefficient between fibers is reduced, the mobility is enhanced, and the inherent smoothness, extension and compression properties of the fibers are restored, so the fabric becomes softer, fluffy and elastic.

[0003] Cationic softeners are the most widely used type, which can be divided into quaternary ammonium salt type, fatty acid ester type, right wax type, polyethylene type, silicone resin type, etc. Among them, quaternary ammonium salt softeners account for a large proportion of cationic softeners, mainly including monoalkyl quaternary ammonium salts, dialkyl quaternary ammonium salts, alkyl acyl quaternary ammonium salts, pyridine quaternary ammonium salts and imidazole softeners. Among quaternary ammonium salt softeners, monoalkyl quaternary ammonium salts have been gradually eliminated due to their high toxicity and poor biodegradability; although the toxicity of dialkyl quaternary ammonium salts and alkyl acyl quaternary ammonium salts is lower than that of monoalkyl quaternary ammonium salts, their biodegradability is very poor, which will kill biological bacteria and is easily absorbed by sludge during sewage treatment and pollute farmland. Silicone softeners have a better lubrication effect, but the biggest disadvantage is that they are expensive, costly, and easy to cause oil floating when used.

[0004] At present, the softener system has defects such as reducing the re-wetting ability of fabrics and affecting the anti-static performance. In addition, this type of softener system products do not have new functional properties such as anti-wrinkle and anti-pilling, and it is difficult to meet market demand. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a fabric antistatic and anti-pilling softener, which has excellent antistatic performance, can greatly reduce the friction coefficient between fibers, and has an excellent anti-pilling effect.

[0006] The technical scheme of the present invention is: an antistatic and anti-pilling softener for fabrics, which is prepared from the following components in parts by weight: 10-20 parts of polyvinyl alcohol, 10-20 parts of hydroxypropyl methylcellulose, 2-10 parts of coconut amine, 1-5 parts of mesoporous phosphate, 1-5 parts of nanographene, 1-5 parts of disodium ethylenediaminetetraacetate, 1-5 parts of water-based fluorine-containing polyurethane, 0.2-2 parts of diquaternary ammonium salt of polydimethylsiloxane, and 80-120 parts of deionized water.

[0007] Furthermore, it also includes 0.1-0.5 parts of osmanthus essential oil.

[0008] Furthermore, 0.5-2 parts of ethylene glycol are included.

[0009] Furthermore, the water-based fluorinated polyurethane is made of the following components in parts by weight: 60-80 parts of isophorone diisocyanate, 2-10 parts of polyglycol, 5-15 parts of dimethylolpropionic acid, 0.2-2 parts of hydroxyethyl methacrylate, 0.2-2 parts of methanol, 0.1-1 parts of neutralizer, 0.1-1 parts of hexafluorobutyl methacrylate, 0.1-1 parts of butyl acrylate, 0.1-1 parts of potassium persulfate, and 0.1-1 parts of sodium lauryl sulfate.

[0010] Furthermore, the preparation method of the water-based fluorinated polyurethane is as follows: comprising the following steps: 1) Under nitrogen protection, add isophorone diisocyanate, polydiol and dimethylol propionic acid into the reaction kettle, control the temperature at 60-100°C, and carry out polycondensation; 2) Continue to add hydroxyethyl methacrylate and methanol to the reactor for end-capping; 3) Adding a neutralizing agent to the reactor for neutralization; 4) Continue to add hexafluorobutyl methacrylate, butyl acrylate, potassium persulfate and sodium dodecyl sulfate into the reactor, keep the temperature at 40-60°C, and continue the reaction to obtain water-based fluorinated polyurethane.

[0011] Furthermore, the neutralizing agent in step 3) is triethylamine.

[0012] The present invention also provides a method for preparing an antistatic and anti-pilling softener for fabrics, comprising the following steps: 1) Activate the mesoporous phosphate with sulfuric acid, wash it, neutralize it with sodium hydroxide and filter it; 2) adding deionized water to the product obtained in step 1) and stirring; 3) Adding nanographene to the solution of step 2) and stirring at high speed; 4) adding polyvinyl alcohol, hydroxypropyl methylcellulose, coconut amine, disodium ethylenediaminetetraacetate and diquaternary ammonium salt of polydimethylsiloxane to the solution of step 3) and stirring; 5) Adding aqueous fluorinated polyurethane to the solution of step (4), stirring evenly, to obtain an antistatic and anti-pilling softener for fabrics.

[0013] The beneficial effects of the present invention are: 1) The softener of the present invention significantly improves the wetting effect and permeability. The active ingredients in the softener can penetrate into the clothing fibers, making the fibers soft and skin-friendly, and having excellent water-repellent, oil-repellent and anti-fouling functions.

[0014] 2) The present invention specifically adds polyvinyl alcohol and coconut amine. The addition of these two ingredients can not only make the product have a certain viscosity, but also achieve good contact between the product and the fabric, thereby increasing the wetting effect.

[0015] 3) The present invention adds mesoporous phosphate and nanographene, loads the nanographene in the mesoporous phosphate, improves the antibacterial property of the softener, has stronger antibacterial activity and more stable performance, and the nanographene has excellent antistatic properties, thereby improving the overall antistatic effect of the softener.

[0016] 4) The addition of water-based fluorinated polyurethane increases the viscosity and toughness of the softener, making the fabric softer and giving the fabric a certain degree of hydrophobicity and hydrophobicity. DETAILED DESCRIPTION
