Embodiment 1

[0025] Such as figure 1 As shown, the silk fabric citric acid anti-wrinkle finishing process of the present invention includes the following processing steps: the real silk sample is immersed in the anti-wrinkle finishing solution in a padding machine, two dipping and two rolling are carried out, the first soaking is 5 minutes, the second time Soak for 3 minutes to make the excess rate 70%. Then use an oven to pre-bake at 85°C for 3 minutes, and bake at 120-150°C for 1-2 minutes. The volume percentage of each component in the anti-wrinkle finishing liquid formula is as follows:

[0026] CA(%): 0-10,

[0027] SHPP(%): 0-9,

[0028] Additive (%): 0-6,

[0029] Penetrant (%): 0.2,

[0030] The rest is water, and the main component of the penetrant is C 7-9 h 15-19 O(CH 2 CH 2 O) 5 H.

Embodiment 2

[0032] The difference with Example 1 is that the volume percentage of each component in the total liquid volume in the anti-wrinkle finishing liquid formula is as follows:

[0033] CA(%): 3-5,

[0034] SHPP(%): 3,

[0035] PAA (%): 4,

[0036] Penetrant (%): 0.2,

[0037] The rest is water.

[0038] Baking conditions are: 130°C×2min.

[0039] Carry out weight gain rate, whiteness value and tear strength performance test to embodiment 2, test result is compared with the situation that CA adopts other dosage and does not carry out anti-wrinkle treatment, data result is shown in the following table 1:

[0040] Table 1

[0041] CA[(w / w)%]

[0042] It can be seen from Table 1 that when the amount of CA is between 0-5%, the crease recovery performance of silk fabrics is gradually improved, and the recovery performance begins to decline after it is greater than 5%. The whiteness of silk fabrics decreased with the increase of CA content, and the weight gain rate increa...

Embodiment 3

[0044] The difference with Example 1 is that the volume percentage of each component in the total liquid volume in the anti-wrinkle finishing liquid formula is as follows:

[0045] CA(%): 6,

[0046] SHPP(%): 3,

[0047] Additive (%): 0-6,

[0048] Penetrant (%): 0.2,

[0049] The rest is water.

[0050] Baking conditions are: 130°C×2min.

[0051] Carry out the performance test of whiteness value to embodiment 3 under the situation of not using additive and using the same amount of different types of additives, the test results are shown in the following table 2:

[0052] Table 2

[0053] Additives

[0054] PAAA

[0055] It can be seen from Table 2 that triethylamine, glyoxal, and PAA as additives can all improve the anti-wrinkle finishing effect of CA on silk fabrics, and PAA has the most obvious improvement on anti-wrinkle effect.

Abstract

The invention relates to a citric acid wrinkle proofing technology for real silk fabrics, which is characterized by comprising the following steps: soaking a real silk sample into a wrinkle proofing solution in a padding machine; soaking and rolling for two times; pre-drying for 3 minutes at 85 DEG C by using an oven; and drying for 1-2 minutes at 120-150 DEG C. According to the wrinkle proofing technology provided by the invention, the settling solution containing CA, namely citric acid, is adopted, so that a wrinkle proofing effect is ensured and the technology is environment-friendly and safe. The influence of wrinkle proofing on the dyeing property of the fabrics is improved, by controlling the reasonable dosage of CA (citric acid) and SHPP (sodium phosphate) and a drying condition. The wrinkle proofing effect is obviously increased by taking a defined amount of PAA (Poly Acrylic Acid) as an additive.

Description

technical field [0001] The invention relates to a cloth finishing process, in particular to a wrinkle-resistant finishing process for real silk fabrics. Background technique [0002] Silk has soft luster, elegant appearance and excellent comfort. It has excellent hygroscopicity and drapability, and has certain health care properties. As a very elegant and noble fabric, it has become one of the most popular high-quality textile materials. One, but the wet elasticity of real silk fabric is low, and it is easy to wrinkle when it is washed at home or in a wet state, causing many inconveniences in the use process. [0003] The low wet elasticity of silk fabric is determined by its fiber structure. Silk protein, unlike wool keratin, has no cystine residues in silk protein and no chemical cross-links between protein molecules. When the fiber absorbs water and swells, the salt bonds between the polymers that give the fiber a high degree of dry wrinkle recovery are destroyed, and t...
