The cotton fiber has good hygroscopicity, can absorb moisture to the surrounding environment under normal conditions, has the moisture content of 8-10%, and can make people feel soft but not stiff when contacting with the skin of a human body; when the humidity of the cotton fiber fabric is too high and the environmental temperature is higher, the moisture in the cotton fiber fabric can be evaporated and dispersed, so that the moisture balance state is kept, and people feel comfortable. In addition, the cotton fiber is a poor conductor of heat and electricity, so the cotton fiber fabric is soft and warm, comfortable to use and widely applied to the clothing industry, the home textile industry and the like.
However, the cotton fiber fabric also has considerable defects, such as easy wrinkling, i.e. easy crease, and influence on use feeling. In order to solve the problem that the cotton fiber fabric is easy to wrinkle, a non-ironing anti-wrinkle treatment process has been developed at present, for example, 2D resin, dimethylol dihydroxy ethylene urea and the like are used as anti-wrinkle finishing agents to carry out anti-wrinkle finishing on cotton fibers, so that the cotton fiber fabric with a good anti-wrinkle effect can be obtained, but the problem of formaldehyde residue exists, and the mechanical property of the cotton fiber fabric is greatly influenced.

A manufacturing method of a cotton fiber fabric comprises the following steps:
s1, preparing a treating fluid and a softening fluid: adding a modifier, a penetrating agent and a catalyst into water to prepare a treatment solution, wherein the modifier is waterborne polyurethane and chitosan; adding the softening agent into water to prepare softening liquid.

S5, drying: drying in an oven at 80 ℃ to constant weight.
S6, spinning: and (4) spinning the cotton fiber obtained in the step (S5) into cotton fiber fabric.
Examples 2 to 5, comparative example 1 and example 1 are different in that: the concentrations of the aqueous polyurethane, the chitosan and the catalyst in the treatment solution are different, the concentrations of the softening solutions are different, and the baking temperature, the baking time and the like are different, which is specifically shown in table 1. In table 1, "\" indicates "none".
Comparative example 2 is a cotton fiber fabric woven using ordinary cotton fibers without modification.
TABLE 1 selection of parameters for examples 1-5 and comparative example 1
The performance of the cotton fiber fabrics of examples 1 to 5 and comparative examples 1 to 2 was tested, the wrinkle recovery angle of the cotton fiber fabrics of the examples and comparative examples was tested by using a YG541B fabric wrinkle resistance tester according to the method described in GB/T3819-1997, and the tensile breaking strength of the cotton fiber fabrics of the examples and comparative examples was tested by using a YG065 electronic fabric strength tester according to the method described in GB/T3923.1-2013, and the specific test results are shown in Table 2.
TABLE 2 tables of Performance test results of examples 1 to 5 and comparative examples 1 to 2
As can be seen from table 2, the wrinkle recovery angles of examples 1 to 5 are all larger than those of comparative examples 1 to 2, and the larger the wrinkle recovery angle is, the better the wrinkle resistance of the cotton fiber fabric is, therefore, the wrinkle resistance of the cotton fiber fabric of the present invention is improved and the crease is not easily generated compared to the common cotton fiber fabric. In addition, the tensile breaking strength of the examples 1 to 5 is not much different from that of the comparative example 2, and particularly the tensile breaking strength of the example 5 is slightly higher than that of the comparative example 2, so that the difference between the mechanical strength of the cotton fiber fabric and the mechanical strength of the common cotton fiber fabric is almost the same, namely the problem that the mechanical property of the cotton fiber is reduced after crease-resistant finishing is solved.
As is clear from comparison between example 4 and comparative examples 1 to 2, when chitosan is absent in the modifier, although the wrinkle recovery angle of comparative example 1 is 192 ° and larger than that of comparative example 2, the wrinkle recovery angle of comparative example 1 is not larger than that of example 4, and the breaking tensile strengths of comparative example 1 are only 194.0N (warp direction) and 87.2N (weft direction), and are not reduced much as compared with that of comparative example 2, which indicates that chitosan plays an essential role in improving the wrinkle recovery angle of the cotton fiber fabric and maintaining the mechanical strength of the cotton fiber fabric.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
