[0032] The present invention also provides a method for preparing hot-melt size for cotton fiber sizing, the specific steps are as follows:
[0033] Step 1. Weigh each raw material according to the mass ratio stipulated in the formula, and mix them in a certain order. Specifically, implement according to the following steps:
[0035] In step 1.1, the antioxidant is antioxidant 1076.
[0036] Step 1.2, mix the raw materials weighed in step 1.1 evenly;
[0037] Step 2. Add the raw materials uniformly mixed in step 1.2 into the container while heating and stirring for a certain period of time. After the raw materials are completely melted into a thick slurry, stop heating and stop stirring;
[0038] The heating temperature in step 2 is 140°C-160°C.
[0039] The heating time in step 2 i...
Embodiment 1
[0051] Take by weight 30% behenic acid, 17% EVA, 15% EAA, 17% paraffin, 8% rosin, 7% copovidone, 5% stearic acid, 1% antioxidant 1076, and the weighed raw materials are mixed evenly. Adjust the reaction temperature at 140°C, add the raw materials into the beaker to heat, stir and observe. Heat for twenty-five minutes, and the raw materials are melted evenly. Stop heating, stop stirring, take out the beaker, wait for the slurry to cool naturally, and make the required slurry.
Embodiment 2
[0053] Weighing mass percent is 33% hexadecanoic acid, 18% EVA, 8% EAA, 17% paraffin, 10% rosin, 7% copovidone, 6% stearic acid, 1% Antioxidant 1076, and the weighed raw materials are mixed evenly. Adjust the reaction temperature at 150°C, add the raw materials into the beaker to heat, stir and observe. Heat for 15 minutes, the raw materials are melted evenly. Stop heating, stop stirring, take out the beaker, wait for the slurry to cool naturally, and make the required slurry.

Abstract
The invention discloses a hot-melt size for cotton fiber sizing, which consists of the following components according to mass percentage: 30%-48% of behenic acid or arachidic acid or hexadecanoic acid, 10%-20% of EVA, 5%-15% EAA, 17% paraffin, 8%-11% rosin, 7% copovidone, 4%-6% stearic acid, 1% antioxidant, the quality of the above components The sum of the percentages is 100%. The hot melt size has high desizing rate, high wear resistance, high strength and low hairiness index. The preparation method of the above-mentioned hot-melt slurry is as follows: step 1, weighing each raw material according to the mass ratio specified in the above formula, and mixing; step 2, adding the uniformly mixed raw materials into the container while heating and stirring for a certain period of time. All raw materials are completely melted into a thick slurry, stop heating and stop stirring; step 3, let the slurry cool naturally, and the required hot-melt slurry can be obtained. The method is simple and easy to operate.
Description
technical field [0001] The invention belongs to the technical field of textile composite materials, and in particular relates to a hot-melt size used for sizing cotton fibers, and also relates to a preparation method of the hot-melt size used for sizing cotton fibers. Background technique [0002] my country is a big textile country, and textile size is the second largest consumption material in the textile industry, with an annual consumption of more than 300,000 tons. At present, the size used for warp yarn sizing on the market mainly includes two categories: natural size and synthetic size. But among them, the adhesion of natural size to synthetic fibers is poor, the mixing process is troublesome, and the sizing performance is not satisfactory; the cooking time of synthetic size is long, easy to skin, and the adhesion to polyester and other hydrophobic fibers is not enough , and it is not easy to degrade and cause pollution after desizing and discharging. Therefore, whe...
