Problems solved by technology

At present, the hydrophilic and easy-to-decontamination finishing agents with the best application effect on the market are modified fluorocarbon resin additives, but most of these hydrophilic and easy-to-decontamination finishing agents are imported, and the cost is very high
In addition, fluorine-based additives will cause fluorine pollution during production and use, and are not environmentally friendly additives

Embodiment 1

[0013] 1. Fabric: 150D / 72F DTY polyester jersey

[0014] 2. Hydrophilic and easy decontamination finishing process

[0015] Dipping method: hydrophilic and easy decontamination finishing agent SR 3% (owf.)

[0016] Dipping temperature 140℃

[0017] Dipping time 25min

[0018] 3. Hydrophilic and easy decontamination performance test method:

[0019] 1. Hydrophilicity test: capillary effect

[0020] Hang the sample (20cm×2.5cm) vertically, immerse the lower end (0.5cm) of the sample in distilled water, and test the height reached by the liquid after 30 minutes.

[0021] 2. Ease of decontamination test: Ease of decontamination test standard refers to AATCC 130-2000 method

[0022] Use a medical dropper to drop 5 drops (about 0.2mL) of engine oil in the middle of the test cloth, cover the top and bottom of the sample with filter paper, press it with a 5kg weight at room temperature for 60s, remove the weight, remove the filter paper, and take out The sample w...

Embodiment 2

[0027] 1. Fabric: 100D / 72F FDY polyester jersey

[0028] 2. Hydrophilic and easy decontamination finishing process

[0029] Dipping method: hydrophilic and easy-to-decontaminate finishing agent SR 4% (owf.)

[0030] Dipping temperature 120℃

[0031] Dipping time 35min

[0032] 3. Hydrophilic and easy decontamination performance test method: same as Example 1

[0033] 4. Test results:

[0034] The capillary effect of the fabric in this case is 20.0cm (the capillary effect without hydrophilic and easy-to-decontamination finishing is 4.1cm), and the capillary effect after washing 50 times is 19.3cm.

[0035] Easy decontamination level: 2 as original, 4.5 for the fabric in this case, and 4.5 after 50 washes.

Embodiment 3

[0037] 1. Fabric: nylon / spandex (97 / 3) blended jersey

[0038] 2. Hydrophilic and easy decontamination finishing process

[0039] Immersion method: hydrophilic and easy decontamination finishing agent SR 5% (owf.)

[0040] Dipping temperature 110℃

[0041] Dipping time 45min

[0042] 3. Hydrophilic and easy decontamination performance test method: the same as in Example 1.

[0043] 4. Test results:

[0044] The capillary effect of the fabric in this case is 10.4cm (the capillary effect without hydrophilic and easy-to-decontaminate finishing is 4.3cm), and the capillary effect after washing 50 times is 9.9cm. (This gross difference from the previous two cases is due to the difference in fabric materials. The effect of hydrophilic and easy-to-decontamination finishing is reflected by the comparison of the gross effect of the fabric before and after finishing. In this case, the treated fabric is better than the untreated fabric. The wool effect of the fabric ...

Abstract

The invention discloses a hydrophilic soil release finish method for fabrics. The method comprises using a soil release finish agent SR produced by Dahua Japan company limited to conduct soil release finish; adopting a padding method to manufacture, enabling using amount of the soil release finish agent SR to be 25-35g / L, enabling rolling remaining rate to be 70-90%, enabling baking temperature to be 170-180 DEG C, and enabling baking time to be 2-3min; or adopting an impregnation method to manufacture, enabling using amount of the soil release finish agent SR to be 3-5%(owf.), enabling impregnation temperature to be 110-140 DEG C, and enabling impregnation time to be 25-45min. The hydrophilic soil release finish method for fabrics uses a chemical hydrophilic modified agent which does not return fluorine to serve as the hydrophilic soil release finish agent, and is low in cost, simple in treatment process and capable of giving excellent hydrophily and easy soil release performance of chemical fibers.

Description

technical field [0001] The invention belongs to the technical field of post-finishing and processing of knitted fabrics, and in particular relates to a hydrophilic and easy decontamination finishing method for fabrics. Background technique [0002] Polyester is hydrophobic and lipophilic, so polyester and its blended fabrics are prone to oil stains during wearing, and the stained oil stains are not easy to wash off, and the washed off oil stains will be stained again. At present, the hydrophilic and easy-to-decontamination finishing agents with the best application effect in the market are modified fluorocarbon resin additives, but most of these hydrophilic and easy-to-decontamination finishing agents are imported, and the cost is very high. In addition, fluorine-based additives will cause fluorine pollution during production and use, and are not environmentally friendly additives. Contents of the invention [0003] The purpose of the present invention is to provide a che...
