Embodiment 1
[0028] Nylon (PA6): polyethylene (PE): ionomer in a weight ratio of 40: 50: 0.1, at a temperature of 280 ° C, a sea-island fiber of 5.0D is obtained through a spinning machine, and 750 g is obtained through a non-woven equipment / m 2 Left and right non-woven fabrics; then ironed to 2.6mm non-woven fabrics, impregnated with PU resin, PE was removed in a toluene tank at 80°C to obtain a PA / PU base fabric; the base fabric piece was made into a 0.8mm thick PA / PU Base cloth, then buffing and finishing to get suede microfiber leather.
Embodiment 2
[0030] PA6: PE: ionomer ratio of 40:50:0.3, 5.5D sea-island fibers were prepared at 270°C, and 750g / m was obtained after carding and laying 2 The non-woven fabric of about 2.6mm is ironed, and after impregnated with PU, PE is removed in a toluene tank at 80°C to obtain a PA / PU base fabric; the base fabric sheet is made into 0.8mm thick PA / PU PU base cloth, then grinding and finishing to get suede microfiber leather.
Embodiment 3
[0032] PA: PE: ionomer ratio of 50:50:0.5, 5.5D sea-island fibers were prepared at 270°C, and 750g / m was obtained after carding and laying 2 The non-woven fabrics of about 2.6mm are ironed, and after impregnated with PU, PE is removed in a toluene tank at 80°C to obtain a colored PA / PU base fabric; the base fabric is made into a 0.8mm thick PA / PU base fabric, then grinding and finishing to get suede microfiber leather.
[0033] In the present invention, due to the effect of ionic compounds, there is a certain amount of cross-linking between the ultrafine fiber "islands" and "islands", which prevents suede from being damaged when products such as gloves, shoes, clothing and bags are made of suede. The shedding of the middle fibers greatly improves the scratch resistance of the suede leather.
