Problems solved by technology

However, there are strong internal stresses between the fibers after drying, and these stresses were not eliminated when the softener was applied, and it was more difficult to eliminate them after the oil film was formed, which caused the fibers to be stressed when the base fabric was stressed The force distribution is uneven, and one by one is subjected to the maximum load and breaks, so that the tear strength of this base fabric is low when it is subsequently processed into synthetic leather.

Embodiment 1

[0036] refer to figure 1, a base fabric post-processing technology of superfine fiber synthetic leather, the base fabric after weight reduction is sprayed with water, and the spraying amount of water is 100ml / m 2 . Then the base fabric is input into the tension roller group, so that the fabric is tensioned, and the tensioned base fabric is processed in the following steps:

[0037] S1: Expanding and drying. Input the base cloth into the drying room, and expand while drying, the expansion rate is controlled at 6%, and the drying temperature of the base cloth in the drying room is 120°C. The drying time of the base cloth in the drying room is 20 minutes.

[0038] S2: oiling treatment. First input the oiling agent into the oiling tank, the liquid level of the oiling agent in the oiling tank is always kept above 2 / 3, and the liquid temperature of the oiling agent is controlled at 35°C. Then the base cloth treated by S1 was input into the oiling tank containing the oiling agen...

Abstract

The invention relates to the technical field of preparation methods of ultrafine fiber synthetic leather, and discloses a base fabric post-processing technology of ultrafine fiber synthetic leather. The base fabric after weight reduction is processed in the following steps: S1: spreading and drying; S2 : oiling treatment; the base cloth after S1 expansion and drying is repeatedly pad-rolled in the oiling agent, and the chemical compositions of the oiling agent are in parts by weight: 40-60 parts of amino silicone oil, aminopropanol kojic acid phosphate 30‑50 parts, 6‑9 parts of diatomaceous earth, 3‑7 parts of talcum powder, and 10‑14 parts of surfactant; S3: styling and drying; S4: skin rubbing treatment. By using the oiling agent mentioned above, the tear strength of the base fabric is improved.

Description

technical field [0001] The invention relates to the technical field of a preparation method of superfine fiber synthetic leather, more specifically, it relates to a post-processing technology of a base cloth of superfine fiber synthetic leather. Background technique [0002] Microfiber synthetic leather is one of the important application products of microfiber. It has the characteristics of high physical properties and strong imitation leather performance. It is widely used in clothing, shoemaking, luggage, furniture and other industries, and occupies a very important role in people's production and life Important position. [0003] For example, the Chinese patent whose notification number is CN109695159A discloses a preparation method of superfiber reverse color cow suede leather, selects polyamide 6 and low-density polyethylene blended cloth as the base cloth, and undergoes resin impregnation, cell control, toluene reduction, After the oiling and kneading finishing, dry ...
