Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0022] A method for producing snowflake synthetic leather, the method comprising the steps of:

[0023] Step 1. Base fabric selection and processing, thickness selection: 1.40-1.50mm, gram weight 400-480g (weight per square meter), blasting: 15fkg / cm 2 Above, warp stretch: 150N / 3cm or more, weft stretch: 500N / 3cm or more, warp elongation 30%-90%, weft elongation 80%-150%, warp tear strength 50N / 3cm Above, the weft tear strength is more than 30N / 3cm double-sided brushed snowflake base fabric, and the front of the base fabric is finely ground with 240 mesh for one version;

[0024] Step 2, the selection of resin and the batching, select big impregnation 5015 resin for use, its resin index: modulus is 20-30%, solid content is at 29-31%, visc...

Abstract

The invention discloses a method for producing snowflake synthetic leather. The method comprises the following steps: Step 1: base cloth selection and treatment, selection thickness: 1.40-1.50mm, gram weight 400-480g (weight per square meter), blasting: 15fkg / cm 2 Above, Warp tensile: 150N / 3cm above, Weft tensile: 500N / 3cm above, Warp elongation 30%-90%, Weft elongation 80%-150%, Warp tear strength 50N / 3cm above. The present invention selects the double-sided snowflake velvet as the base fabric. Since the base fabric will have uneven wool during the napping process, the snowflake velvet has high requirements for the base fabric, and deep processing needs to be carried out internally. Fine grinding treatment to ensure that there are no abnormal phenomena such as dead wrinkles and small particles on the surface of the finished product to achieve the consistency of cloth and wool. The wet method uses a large impregnation process to make the wet polyurethane resin evenly distributed and penetrated into the double-sided snowflake fleece. The polyurethane penetration is 1600g / m 2 left and right, so that the double-sided snow fleece has support and resilience, and the hand feels soft and comfortable and has breathability.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a method for producing snow suede synthetic leather. Background technique [0002] Snowflake velvet is also called cashmere velvet and Oron velvet. Snow velvet fabric is a kind of warp knitted fabric, which is currently on the market. The fabric is made of special silk and polyester yarn, unique weaving process, advanced dyeing and finishing technology, which makes the fabric suede rich and fresh and refined, so it attracts customers to linger and occupy the recent sales hot spot in the market. The characteristics of snowflake velvet: It has the characteristics of soft hand feeling, light texture, cold and warm protection, corrosion resistance, light resistance and no bloated feeling. It is comparable to and superior to animal leather, and it is super natural, environmentally friendly, and healthy leather that does no harm to the human body. Widely used in the manufac...
