Combining example 1, comparative example 1 and untreated clothing, and combining tables 2 and 3, it can be seen that, compared with untreated clothing, the anti-wrinkle finished clothing has the ability of swelling and the like due to the polyethylene glycol strong protectant, when the finishing agent reacts with cellulose fibers, the orientation ability between hydrogen bonds and decomposition increases, thereby improving the strong retention rate of the fabric, increasing the wrinkle recovery angle, losing the strength, reducing the whiteness, increasing the stiffness, and enhancing the DP grade.
In combination with examples 1-5 and with tables 2 and 3, it can be seen that, with sequential addition of the softener amino silicone oil, the penetrant M and the bulking agent formic acid in the anti-wrinkle finishing liquid, the stiffness of the fabric is reduced, the fabric is not easy to yellow, the dye is not easy to change color, the finishing agent and the fiber react sufficiently in the presence of the penetrant, the reaction rate is improved, the finishing agent enters the inside of the fiber conveniently and rapidly in the presence of the bulking agent, the wet elasticity of the fabric can be enhanced, the crease recovery angle is not reduced, and is raised to some extent, meanwhile, the strength loss is reduced, and the DP grade is not changed greatly.
In combination with examples 5-7 and with Table 3, it can be seen that the crease recovery angle and strength loss of the crease-resistant apparel fabric are not greatly different in the presence of the additives such as the strong protectant polyethylene glycol and the catalyst, and the DP grade and whiteness and hardness are not greatly changed. It is shown that the high crease recovery angle and low strength loss can be achieved also when the temperature is lower than the temperature in the prior art in the presence of polyethylene glycol.
It can be seen from the combination of examples 5,8 and 9 and the combination of tables 2 and 3 that the crease recovery angle of the treated crease-resistant clothing becomes larger, the retention of breaking strength and the retention of tearing strength are also increased, and the DP grade is also increased, compared with the single finishing agent, the performance of the clothing obtained by mixing glyoxal and tricarballylic acid as the finishing agent is better, and the gain effect is better.
In combination with examples 5, 10, 11, and with tables 2 and 3, it can be seen that the overall change in crease recovery angle and strength loss was increased for the various catalyst combinations relative to the individual catalysts, with little change in DP grade due primarily to the gain effect of the various catalysts after combination. However, the crease-resistant clothing performance after mixed finishing of the two catalysts is not greatly different from the crease-resistant clothing performance after mixed finishing of the three catalysts.
In combination with examples 5, 12 and 13, the blend of multiple softeners had reduced hardness relative to the single softener, but at the same time the crease recovery angle was increased and the DP rating was reduced. Based on analysis of various properties, a single softener is preferred.
By combining example 5, comparative example 1 and comparative example 2 and combining tables 2 and 3 and by modifying the types of catalysts in comparative example 5 and comparative example 1, the fluctuation of the crease recovery angle is small and the change of the strength loss is obvious under the condition that other conditions are unchanged. By the comparison example 5 and the comparison example 2, the crease recovery angle of the crease-resistant clothing fabric is not changed greatly when polyethylene glycol is absent, and the strength loss value is large.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
