A zwitterionic resin is manufactured by a manufacturing method which includes the following steps. A first thermal process is performed on a first crosslinking agent and a choline having hydroxyl group or amino group to form a first mixture, in which the first crosslinking agent includes an isocyanate group. A second thermal process is performed on the first mixture, a second crosslinking agent, a chain extender, and an amino acid to form the zwitterionic resin, in which the chain extender includes a polyol.

To provide an antifouling processing agent composition capable of imparting oil repellency and antifouling properties (stain release properties), while suppressing a reduction in the water absorbency of a textile product. This antifouling processing agent composition comprises: a fluorinated polymer comprising from 30 to 70 mass % of units based on F(CF.sub.2).sub.nY—OCOCR═CH.sub.2 (wherein Y is an alkylene group, and R is a hydrogen atom, an alkyl group, or a halogen atom) and from 20 to 60 mass % of units based on CH.sub.2═CR.sup.1—COO—(R.sup.2O).sub.q—R.sup.3 (wherein R.sup.1 is a hydrogen atom or a methyl group, R.sup.2 is an alkylene group, and R.sup.3 is a hydrogen atom, an alkyl group, a (meth)acryloyl group, or a glycidyl group), and having a number average molecular weight of 3,000-500,000; and a fluorinated amphoteric surfactant having a C.sub.1-6 perfluoroalkyl group or a C.sub.3-9 perfluoroalkenyl group, and having a number average molecular weight of less than 3,000.

A fluorine-free carbon chain hydrophobic fabric, and its preparation method and application. A fabric is sequentially soaked in an alkali liquor and an acid liquor to obtain a pretreated fabric; the pretreated fabric then reacts with bromoacetyl bromide to obtain a treated fabric; the treated fabric then reacts with 1,2-bis(p-toluenesulfonyl) hydrazine to obtain a diazotized fabric; the diazotized fabric reacts with a diazoacetate monomer to obtain a fluorine-free carbon chain hydrophobic fabric; and the diazoacetate monomer is butyl diazoacetate, hexyl diazoacetate, octyl diazoacetate, dodecyl diazoacetate, tetradecyl diazoacetate or octadecyl diazoacetate. According to the scheme, diazoacetate is used as a monomer, and different fiber grafting modification processes are used, so as to form different structures on the fiber surface; and the comprehensive properties such as thermal stability, air permeability and breaking strength of the finished fabric are tested, the heat resistance and breaking strength of the finished fabric are reduced, and the air permeability is good.
