Embodiment Construction

[0020] Below in conjunction with example further illustrate the present invention.

[0021] The tanning process embodiment of the present invention's flame-retardant, light-resistant, low-atomization degradable cowhide automobile seat cushion leather manufacturing process includes the following steps carried out in sequence: grouping, soaking, fleshing, liming, fleshing and skinning, deliming, softening, pickling, tanning, aging, shaving, rewetting, retanning, draining after retanning and washing, neutralization, draining and washing after neutralization, fatliquoring, draining and washing after fatliquoring, dyeing And electrostatic conditioning, water squeezing and stretching, wet shaking, vacuum drying, shaking, softening and coating.

[0022] The deashing process is as follows: the bath liquid ratio is 200%, the bath liquid temperature is 19~20°C, add 1% deliming agent, rotate for 120min, and measure the bath liquid pH9.0.

[0023] In nine deashing experimental schemes, m...

Abstract

The invention discloses a manufacturing technology for flame-retardant, light-resistant, low-fogging and degradable cowhide car seat cushion leather. According to the manufacturing technology, ammonium salt deliming is replaced by ammonium-salt-free deliming, tetrakis hydroxymethyl phosphonium sulphate and a flame-retardant starch-type leather surfactant are selected as a leather tanning agent to replace a traditional chrome tanning agent, the fogging value of the seat cushion leather is reduced through high-temperature washing, the flame-retardant property of the leather is improved through retanning, fat liquoring and coating step by step, the light resistance of a coating is improved through a light-resistant material, and the usage quantity of leather chemicals is decreased by selecting roll coating to replace spray coating.

Description

technical field [0001] The invention relates to a manufacturing process of cowhide automobile seat cushion leather, in particular to a manufacturing process of flame-retardant, light-resistant, low-atomization degradable cowhide automobile seat cushion leather. Background technique [0002] From the perspective of the development history of the world's automobile industry, the output and sales of cars have increased exponentially with the improvement of human material living standards. Every 2 people in developed countries own 1 car. Since my country joined the World Trade Organization in 2001, the production and sales of cars in the market have soared. In 1991, the output was only 81,000, and by 2002 it reached 1.092 million. In 2014, the sales of cars exceeded 23 million. With the growth of automobile production, its supporting industry, the automobile interior decoration industry, is bound to grow rapidly and become more and more high-end. The amount of leather applied ...
