Problems solved by technology

It is now considered to use hydrophilic softening agents to improve the softness and comfortable fluffy feel of fabrics, and at the same time endow fabrics with certain hydrophilic properties. However, there are few hydrophilic softening agents for polyester-cotton fabrics on the market, and most polyester-cotton fabrics are The auxiliary agent used in the hydrophilic softening finishing of the fabric is a hydrophilic softening agent for polyester or cotton, which can only act on a single component in the polyester-cotton fabric, so the finishing effect is also general

Abstract

The invention discloses a hydrophilic soft finishing agent applied to a polyester-cotton fabric material. The hydrophilic soft finishing agent is prepared from the following raw materials: acylate W,dimethyl terephthalate, ethylene glycol, 5-{[3-(4-nitrophenyl)-3-oxo-propyl alcohol]amino}dimethyl isophthalate and a catalyst A. The acylate W is a product of an acylation reaction among 2-hydroxy adipic acid, diethylenetriamine, stearic acid and a catalyst B. The polyester-cotton fabric material is treated by adopting the finishing agent provided by the invention, so that the fabric has excellent properties such as hydrophilic property, antistatic property and fastness to washing and loose, soft and smooth comfortable effects. The problems that the amount of hydrophilic soft finishing agentsfor polyester-cotton fabrics is small at present and the finishing effect is general because polyester or cotton based hydrophilic soft finishing agent only acts on a single component in the polyester-cotton fabric are solved, the service performance of the polyester-cotton fabric material is improved, the application range is widened, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a hydrophilic softening agent for polyester-cotton fabric materials. Background technique [0002] Polyester-cotton refers to the general term for blended fabrics of polyester and cotton. It is a textile made of 65% to 67% polyester and 33% to 35% cotton blended yarn, commonly known as "Dacron", which is a common material for making clothes. Polyester-cotton not only highlights the style of polyester but also has the advantages of cotton fabric. It has good elasticity and wear resistance under dry and wet conditions, stable size, small shrinkage, and has the characteristics of tall and straight, not easy to wrinkle, easy to wash, and quick-drying. features. [0003] Polyester-cotton fabrics are widely used in daily life due to their excellent properties, but the hand feeling and wearability of polyester-cotton blended fabrics are greatly reduced after a series of pre-...
