Abstract

The invention discloses non-woven embroidering lining paper. The non-woven embroidering lining paper takes softwood pulp as a main raw material, and is characterized by further comprising rayon fibers, chemical fibers and a sizing agent, wherein the content of the rayon fibers accounts for 30% to 55% of the dry weight of the lining paper; the content of the chemical fibers accounts for 15% to 20% of the dry content of the lining paper; the content of the sizing agent accounts for 8% to 15% of the dry content of the lining paper; the balance is the softwood pulp; the chemical fibers are polyester fibers, polypropylene fibers, composite fibers of the polyester fibers and the polypropylene fibers, composite fibers of the polypropylene fibers and polyethylene fibers, or composite fibers of the polyester fibers and the polyethylene fibers. A preparation method of the non-woven embroidering lining paper comprises the steps of carrying out pulping, carrying out pulp blending, carrying out pulp washing, carrying out papermaking, carrying out squeezing and drying, carrying out sizing and carrying out drying to form paper. According to the non-woven embroidering lining paper disclosed by the invention, artificial silk fibers, which are added into the raw materials, have the characteristics of high strength and good flexibility and can meet the characteristics of low paper basis weight, soft hand feeling and great vertical and horizontal tensile strength of the non-woven embroidering lining paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a non-woven embroidery interlining paper and a preparation method thereof. Background technique [0002] The embroidery backing paper is a layer of accessories laid under the fabric to stabilize the stitches and improve the smoothness of the embroidery. The backing paper for textile embroidery is the backing material for machine embroidery and hand embroidery of high-grade fabrics. The backing paper is required to have high longitudinal and transverse tensile strength, small longitudinal and transverse tensile force ratio, small expansion ratio, high wet tensile strength, and low paper weight. , soft feel and so on. However, the non-woven embroidery interleaving paper currently on the market often cannot meet the characteristics of low basis weight and soft hand feeling. SUMMARY OF THE INVENTION [0003] The first object of the present invention is to overcome...
