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] Reference figure 1 , A post-processing technology for the base fabric of microfiber synthetic leather. The base fabric after weight reduction is sprayed with water, and the spray amount of water is 100ml / m 2 . Then input the base fabric into the tensioning roller group to make the fabric tensioned. The tensioned base fabric is processed as follows:

[0037] S1: Spreading and drying. Input the base fabric into the drying room, and expand while drying, the expansion rate is controlled to 6%, and the drying temperature of the base fabric 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. The oiling agent is first input into the oiling tank, the liquid level of the oiling agent in the oiling tank is always maintained above 2 / 3, and the liquid temperature of the oiling agent is controlled to 35°C. Then input the base fabric after S1 treatment into the oiling tank containing the oiling agent, and repea...

Abstract

The invention relates to the technical field of preparation methods of superfine fiber synthetic leather, and discloses a base fabric post-processing technology of superfine fiber synthetic leather. Adecreased base fabric is treated by the technology comprising the following steps: S1, expanding and drying; S2, oiling, wherein the base fabric which is expanded and dried in step S1 is repeatedly soaked in an oiling agent. The oiling agent comprises the following chemical components in parts by weight: 40-60 parts of amino silicone oil, 30-50 parts of aminopropanol kojic acid phosphate, 6-9 parts of diatomite, 3-7 parts of talcum powder and 10-14 parts of a surfactant; S3, shaping and drying; and S4, carrying out puffing treatment. By using the oiling agent mentioned above, the tearing 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, and more specifically, it relates to a post-processing technique of a base fabric 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 simulated leather performance. It is widely used in clothing, shoemaking, luggage, furniture and other industries, and it accounts for a lot of people's production and life. Important position. [0003] For example, the Chinese patent with the publication number CN109695159A discloses a method for preparing super-fiber inverted cow suede. Polyamide 6 and low-density polyethylene blended fabric are selected as the base fabric, and the resin is impregnated, cell control, toluene reduction, After oiling, kneading and finishing, dry laminating steps, three-l...
