Description
Technical Field
The invention relates to the technical field of textile printing and dyeing, in particular to a durable antistatic agent for polyester fabrics and a preparation method of the polyester antistatic fabrics.
Background
The polyester fiber is a synthetic fiber with the largest use amount at present, has large yield and wide application range compared with natural fibers, and simultaneously has excellent characteristics which are not possessed by various natural fibers. However, because the structure of the polyester fiber lacks hydrophilic groups, the hydrophilicity is extremely low, and static electricity accumulation is easily caused by friction under dry weather conditions, which brings adverse effects to the processing of the polyester fiber and the use of polyester fabrics. Therefore, antistatic finishing of the terylene and the blended fabrics thereof is particularly necessary.
Most of antistatic agents commonly used in the existing polyester post-finishing processing are micromolecular inorganic salt, organic salt, low molecular surfactant or macromolecular polyester, but the micromolecular and low molecular type antistatic agents are generally disposable antistatic treatment agents due to small molecular weight; the antistatic effect of the macromolecular polyester depends on the environment humidity, is not as good as that of micromolecules, and is also poor after washing.
The fabric static electricity remover disclosed in patent CN201110456700.8 comprises polyol, silicone oil, cationic surfactant, amphoteric surfactant and deionized water; the fabric static electricity remover is compounded by utilizing the antistatic property of a surfactant, the hygroscopicity of polyalcohol, the softness of silicone oil and other properties, so that the fiber surface has hygroscopicity and ionicity, the conductivity of the fiber surface is improved, and the aim of preventing static electricity is fulfilled. But the fabric has the defect of only having good one-time antistatic effect, and after the fabric is washed, the components of the antistatic agent are washed away, so that the fabric has no washing-resistant effect. Patent CN201611128931.5 discloses a multifunctional finishing agent for terylene, which contains polyester polyether polymer as main component, and its wash-resistant antistatic effect is superior to that of general low molecular substance, but it still can not meet the antistatic requirement of wash-resistant frictional charge voltage below 3000V.
An antibacterial and antistatic finishing agent is described in patent 201910028753.6 published by Qingdao university application, and the finishing agent comprises 100 parts by mass of water, 4-10 parts by mass of betaine, 10-20 parts by mass of siloxane polymer, 0.5-5 parts by mass of water-soluble hydrophobic association polymer and 2-5 parts by mass of cyclodextrin. The antibacterial and antistatic finishing agent is loaded on the synthetic fiber fabric, so that the antibacterial and antistatic performance of the synthetic fiber fabric can be effectively improved, and the washability and durability of the antibacterial and antistatic finishing agent on the synthetic fiber fabric are improved. However, the presence or absence of betaine has little effect on its wash resistant antistatic effect and the use of betaine is preferably cocamidopropyl hydroxysultaine.
