Abstract
The invention discloses a polyether ester for the adhesion of a textile adhesive, aiming to solve the problem that a material which is more sensitive to the temperature in the traditional polyether ester for the textile adhesive is easy to be damaged. The polyether ester comprises terephthalic acid, isophthalic acid, 1,4-butanediol and polyethylene glycol, wherein the molar ratio of the terephthalic acid to the isophthalic acid is 40-45:60-50, and the mass of the polyethylene glycol is 10.5-25 percent of the total mass of the polyether ester. With the adoption of the polyether ester for the textile adhesive, when being processed and ground, the polyether ester is not easy to be damaged; and meanwhile, a melting point of the polyether ester descends, and the polyether ester is more convenient to be used.
Description
Technical field
The present invention relates to a kind of for the bonding polyether ester of bonding of textiles agent.
Background technology
At present, existing people disclosed many different copolyesters that are used as textiles hot pressed powder polymkeric substance.Only containing in the group situation of low molecular weight dicarboxylic acids and dibasic alcohol, this kind polyester is stable not for the effect that resembles used organic solvent of textiles when dry-cleaning.This kind polyester is used for the common textiles that only washes with water mostly, for example is used to increase very collar, cuff and blouse.In order to obtain to bear the bonding of textiles that washing also can stand to dry-clean, once the someone delivered the application that reaches a standard in the block copolymerization polyether ester.For example JP-A54-153835 discloses a kind of polyether ester as the spun bonded agent, it comprises a) terephthalic acid group, the b of 70～40% (moles)) 30～60% (mole) m-phthalic acid group, c) 1,4-butyleneglycol group, and d) (a) to d) gross weight) 1～10% a kind of polyalkylene ether glycols group, the molar mass of this polyalkylene ether glycols group is 0.3～6kg/mol, all components all in all polycondensation combine; Component d) comprises polyoxyethylene glycol, although poly-BDO is better.Because component d) content lower, so the melt viscosity of this polyester is higher, to produces the higher underground heat of the bonding needs of tackiness agent-pressures temperature and/or grow and press (subsides) and close time or elevated pressures.Therefore, thisly in this course of processing, may sustain damage under the certain environment than more sensitive material to temperature.
Summary of the invention
Goal of the invention of the present invention is: for the present existing problem that temperature is sustained damage easily than more sensitive material for the polyether ester of bonding of textiles agent, provide a kind of for the bonding polyether ester of bonding of textiles agent, product of the present invention is when processing and grinding, not fragile, its melting point depression is more easy to use simultaneously.
To achieve these goals, the present invention adopts following technical scheme:.
A kind of for the bonding polyether ester of bonding of textiles agent, comprise terephthalic acid, m-phthalic acid, 1,4-butyleneglycol and polyoxyethylene glycol, the mol ratio of described terephthalic acid and m-phthalic acid are 40～45:60～50, and the quality of described polyoxyethylene glycol is 10.5～25% of above-mentioned polyether ester total mass.
The mol ratio of described terephthalic acid and m-phthalic acid is 42: 58 or 45: 55.
The BDO of 1%-20%mol replaces with hexylene glycol.
The BDO of 5～10%mol replaces with hexylene glycol.
The polyoxyethylene glycol of 5%-10%wt is with two or triglycol, and perhaps lower molecular weight alkylene ether glycol replaces.
Applicant of the present invention finds, have product that a high proportion of like this m-phthalic acid and polyoxyethylene glycol consist of unexpectedly can be processed with grinding and no problem, with regard to the knowledge of now having grasped, this is seemingly impossible.And, also found melting point depression almost 20 ℃ (DSC (differential scanning calorimetry): 103～108 ℃), thus more easy to use.It far is high bounding force to important cladding material with above-mentioned also being of combining.However, also may greatly reduce the back side is clamminess.
As required, the additive as grinding aid such as nucleator (for example micronization talcum), static inhibitor, lubricant or wax can also directly be added or adding in the polyether ester process of lapping or after this process in the polyether ester melt.
