Figured island superfine fiber, figured island superfine fiber synthetic leather base cloth, suede leather for clothes, smooth synthetic leather for clothes and production method of fiber, base cloth, suede leather and smooth synthetic leather

Abstract

The invention relates to figured island superfine fiber, figured island superfine fiber synthetic leather base cloth, suede leather for clothes, smooth synthetic leather for clothes and a production method of the fiber, the base cloth, the suede leather and the smooth synthetic leather and belongs to the technical field of synthetic leather and production method of the synthetic leather. The production method of the figured island superfine fiber mainly comprises the steps of 1), performing slice drying and fusion; 2), conducting composite spinning; 3), applying oil and dropping a bucket; 4), performing drafting and crimping; and 5) drying and cutting off the fiber. The figured island superfine fiber synthetic leather base cloth, the suede leather for clothes and the smooth synthetic leather for clothes can be produced through the follow-up processing of the figured island superfine fiber. A prepared synthetic leather product has excellent mechanical property, dyeing property and color fastness, is more suitable for synthetic leather of suede or synthetic leather for clothes, which is prepared by surface making, roller coating and surface printing deep processing based on the suede leather, and product application of the leather, and the product is high in durability, strong in color fastness, convenient to cut, fashionable in product design, moisture permeable, vapor permeable, fine and smooth in sensing of suede, and good in writing effect.

Description

technical field [0001] The invention relates to Dingdao superfine fiber, Dingdao superfine fiber synthetic leather base cloth, suede leather for clothing, smooth synthetic leather for clothing and a manufacturing method thereof, and belongs to the technical field of synthetic leather and the manufacturing method thereof. Background technique [0002] Microfibers for synthetic leather are divided into fixed-island type and indeterminate-island type, and synthetic leather based on non-fixed-island microfibers has developed rapidly in the world in recent years, especially in China's synthetic leather industry. The product system focuses on the development of synthetic leather products based on extractable non-stationary superfine fibers. The product technology and product applications are highly homogeneous, and the scale is extremely serious, which greatly restricts the technological upgrading and application field expansion of the synthetic leather industry. With the expansio...

AI Technical Summary

Problems solved by technology

At present, the synthetic leather based on non-Dingdao microfiber technology can not meet this demand, and Dingdao microfiber polyurethane synthetic leather products are excellent in color development, color fastness, fine velvet appearance, writing effect and fashionable color. It is superior to the existing non-fixed island microfiber polyurethane synthetic leather products in terms of texture and other aspects, and has broad application prospects and development potential in high-end fields such as automobiles, furniture interiors, clothing, fashion footwear, etc.
