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, not all of the embodiments.

[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...

Abstract

The invention discloses a cashmere wool synthetic leather production method. The method includes steps: step 1, base cloth selection and treatment, to be specific, selecting base cloth in thickness of1.40-1.50mm, in gram weight of 400-480g (weight per square meter), in blasting of 15fkg / cm<2> or above, in warp drawing of 150N / 3cm or above, in weft drawing of 500N / 3cm or above, in warp elongationof 30%-90%, in weft elongation of 80%-150% and in warp tear strength of 50N / 3cm or above. By selection of two-sided cashmere wool as the base cloth, due to nonuniformity in wool distribution on the base cloth in a galling process, the cashmere wool is high in requirement on the base cloth, internal deep processing is required, and 240-mesh abrasive paper is adopted for fine grinding of the front face of the two-sided wool to guarantee the surface of a finished product against abnormities such as creases, small particles and the like, and cloth-wool uniformity is realized. By an impregnation process for a wet method, wet-method polyurethane resin is uniformly distributed and permeates into the two-sided cashmere wool, the polyurethane resin permeation quantity is about 1600g / m<2>, and supporting and resilience properties, softness and comfort in hand feeling and breathability of the cashmere wool are achieved.

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...
