Description
Technical field
The present invention relates to textile finishing technical fields, more specifically, it is related to a kind of floride-free water-proof aagent and its system
Standby and methods for using them.
Background technique
Textile finishing refers to that all process for improving fabric quality are whole except scouringing and bleaching, dyeing, in addition to stamp
Reason content generally comprise make fabric door width is neat, size modes stablize, improve fabric feeling, promote appearance of fabrics and it is fire-retardant,
Water repellent, other arrangements such as refuse oily, hygienic, antistatic, easy decontamination；It is different for the field of employment of fabric, it is arranged selected from corresponding
Content.For the shower curtain in bathroom, material is mainly textile fabric and plastic material, and textile fabric comes compared to plastic material
It says, ageing-resistant performance and tear-resistant ability are stronger, therefore the service life is longer for the shower curtain of textile fabric, textile fabric
Shower curtain is more widely applied；Existing shower curtain is usually terylene material with textile fabric, since the humidity in bathroom is higher, is got wet
Polyester fabric afterwards is not easy drying, leads to its bacterium easy to breed, generates peculiar smell, therefore the polyester fabric of shower curtain usually requires
Carry out water-proof finish.
Common fabric waterproof finishing agent includes fluorocarbon polymer, organosilicon, long chain alkane polymer knot currently on the market
The water-proof aagent of structure.Fluorine-containing water repellent with preferable crystallinity, bulk density, thus with excellent waterproof due to imitating
Fruit；But organic fluorine chemistry product PFOS (perfluorooctane sulfonate) and PFOA (perfluoro caprylic acid), to human body there is bioaccumulation,
Different degrees of toxicity, persistence and potentially hazardous, therefore to receive some countries different degrees of for fluorine-contained finishing agent at present
Limitation, thus the research that people put on floride-free water-proof aagent is more and more, current floride-free water-proof aagent is mainly
Long chain alkane class waterproofing agent and waterproofing agent of organosilicon, although floride-free water-proof aagent is not easy to accumulate in vivo, endanger to human body

Illustrate that the addition of the waterproof synergistic agent in embodiment 4-5 not only facilitates raising waterproof performance, also contributes to improve water-fast
Wash secured performance.
The crosslinking agent in floride-free water-proof aagent in reference examples 1 is conventional cross-linking agent, compared to application examples 1, fabric
Waterproof performance after waterproof performance and washing is declined, and illustrates that crosslinking agent prepared by the present invention can be obviously improved fabric
Waterproof performance, be particularly useful to improve water-fastness secured performance.
Poly- (the Asia the oxygen -1,2- second of α-isotridecyl-ω-hydroxyl-is not included in floride-free water-proof aagent in reference examples 2
Base), compared to application examples 1, the waterproof performance and the waterproof performance after washing of fabric are declined slightly, and illustrate the different tridecane of α-
The addition of base-ω-hydroxyl-poly- (oxygen -1,2- ethylidene) helps to improve the waterproof performance of floride-free water-proof aagent.
The crosslinking agent in floride-free water-proof aagent in reference examples 3 is conventional cross-linking agent, compared to application examples 4, fabric
The waterproof performance and the waterproof performance after washing of waterproof fabric are declined, and illustrate crosslinking agent prepared by the present invention and waterproof
It can be obviously improved the waterproof performance of fabric after synergist cooperation, be particularly useful to improve water-fastness secured performance.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
