Abstract

The invention discloses a dyeing and finishing process of knitted fabric which comprises the following steps of firstly, pretreating; secondly, dying; thirdly, finishing: sequentially feeding 1 to 2 parts by weight of gamma-(methacryloyloxyethy) propyltrimethoxysilane, 0.4 part by weight of dimethylformamide, 1.3 parts by weight of 4,5-dichloro-2-n-octyl-3-isothiazolinone and 0.9 part by weight of sodium acetate into 15 parts by mass of deionized water and uniformly stirring; then simultaneously feeding 0.7 part by weight sodium pentachlorophenate, 0.5 part by weight of 1,3,5- triglycidylisocyanurate, 1,4 parts by weight of dimethyl terephthalate and 0.9 part by weight of octamethylcyclotetrasiloxane, and continuously stirring until the materials are fully and uniformly mixed to obtain a finishing liquid; subsequently performing padding treatment on fabric in the finishing liquid, taking out and then drying the treated fabric at constant temperature. According to the dyeing and finishing process of the knitted fabric, disclosed by the invention, the dyed and finished fabric has excellent flame-retardant, mothproof, mouldproof, antibacterial and antistatic properties; in addition, the dyed and finished fabric is high in washability and is soft in hand feeling.

Description

technical field [0001] The invention relates to a dyeing and finishing process for knitted fabrics. Background technique [0002] The flame retardant, anti-mite, anti-mildew, anti-bacterial, anti-static, and washable properties of the existing fabrics need to be improved, and the hand feeling is not soft enough. Contents of the invention [0003] The object of the present invention is to provide a dyeing and finishing process for knitted fabrics. The dyed and finished fabrics have excellent flame-retardant, moth-proof, mildew-proof, anti-bacterial and anti-static properties, and are strong in washability and soft to the touch. [0004] In order to achieve the above object, the technical solution of the present invention is to design a dyeing and finishing process for knitted fabrics, comprising the steps of: [0005] 1) Pretreatment; [0006] 2) dyeing; [0007] 3) Finishing: 1 to 2 parts by weight of γ-(methacryloyloxy)propyltrimethoxysilane, 0.4 parts by weight of dim...
