New softener for cloth

Abstract

The invention discloses a new softener for cloth. The new softener for the cloth comprises the following raw materials in parts by weight: 4 to 7 parts of glutaraldehyde, 5 to 8 parts of MgCl2.6H2O, 10 to 20 parts of waterborne polyurethane resin, 2 to 5 parts of a triethanolamine oleic acid soap, 3 to 7 parts of amino silicone oil, 9 to 11 parts of polyoxyethylene ether, 12 to 16 parts of dioctadecyl dimethyl ammonium chloride, 1 to 4 parts of tartaric acid, 10 to 12 parts of polyvinyl butyral, 11 to 14 parts of sodium dihydrogen phosphate, 3 to 7 parts of sodium dodecyl benzene sulfonate, 1to 4 parts of valerolactam, 4 to 6 parts of fatty acid polyoxyethylene ester, and 45 to 55 parts of deionized water. The new softener for the cloth disclosed by the invention has the beneficial effects that (1) the softer is non-toxic and harmless to human bodies, free of environmental pollution, good in safety, excellent in hygroscopicity and breathability, free of influences on the color and whiteness of the cloth, soft in handfeel, and good in crease resistance and durability; and (2) the cloth treated by the softener is high in wear resistance, good in elasticity, and convenient in production and low in cost.

Description

technical field [0001] The invention relates to the field of non-woven fabric production, in particular to a novel softener for cloth. Background technique [0002] Soft finishing is an important finishing process in printing and dyeing processing. During the processing of textiles, the handle will become rough after repeated treatments, and the synthetic fiber fabrics are generally worse, especially the microfiber fabrics. In order to make the fabric soft, smooth and comfortable, it needs to be finished. At present, it is widely used to finish with softener. In addition, a large amount of softeners are used in chemical fiber spinning, spinning and weaving of various fibers. The friction between them increases, which is prone to scratches, streaks and other phenomena. The use of softener can make the fiber itself have softness and smoothness suitable for processing conditions to avoid damage. Therefore fabric softener is an important textile auxiliary.

Problems solved by technology

[0004] Cationic softener is the most widely used category, and it can be divided into quaternary ammonium salt type, fatty acid ester type, right wax type, polyethylene type, silicone resin type, etc. Occupy a large proportion in the agent, mainly mono-alkyl quaternary ammonium salt, dialkyl quaternary ammonium salt, alkyl acyl quaternary ammonium salt, pyridine quaternary ammonium salt type and imidazole type softener, etc., the currently used quaternary ammonium salt type softener The single alkyl quaternary ammonium salt in the agent has been gradually eliminated due to its high toxicity and poor biodegradability; although the toxicity of the dialkyl quaternary ammonium salt and the alkyl acyl quaternary ammonium salt is lower than that of the single alkyl quaternary ammonium salt, their biodegradation It is very poor in nature, will kill biological bacteria and is easy to be absorbed by sludge during sewage treatment and pollute farmland. Therefore, it has been discontinued in Germany, the Netherlands and other countries in the early 1990s. The European Union released it on May 15, 2002. Bis[hydrogenated tallow alkyl] dimethyl ammonium chloride, bis [stearyl] dimethyl ammonium chloride and bis [tallow alkyl] dimethyl ammonium chloride and Preparations or formulations composed of them; as for cationic softeners such as imidazole type (such as softener IS) and pyridine quaternary ammonium salt type (such as VelanPF), the BOD is small, and it is difficult to deal with degradation by traditional biochemical methods, although there is currently no disabled, but their use is also problematic by ecological requirements
