Non-woven fabric coating process with effect of effectively increasing adhesive force

Abstract

The invention discloses a non-woven fabric coating process with an effect of effectively increasing adhesive force. The non-woven fabric coating process includes steps of 1), preparing adhesive powder, and to be more specific, selecting ethylene-vinyl acetate copolymer adhesive powder particles with the particle sizes of 290-320 nm and the weight proportions higher than 80%; 2), preparing resin solution, to be more specific, acquiring 20 parts of acrylic resin with the glass transition temperature Tg point lower than -35 Celsius degrees, sequentially adding 0.5 part of ammonia water and 79.5 part of water into the acrylic resin and uniformly mixing the ammonia water, the water and the acrylic resin with one another to obtain the resin solution; 3), acquiring non-woven fabrics, and uniformly attaching 14g / m<2> of resin solution on the non-woven fabrics; 4), uniformly sprinkling the adhesive powder particles on the surfaces with the attached resin solution. The non-woven fabric coating process has the advantage that the adhesive force of the non-woven fabrics of linings can be greatly increased, can reach 0.53 mgf, is greatly superior to adhesive force, which is 0.30 mgf, of generallinings, and can be enhanced by nearly 77%.

Description

【Technical field】 [0001] The invention relates to a non-woven fabric, in particular to a non-woven fabric gluing process which can effectively improve the adhesive force. 【Background technique】 [0002] Clothing linings are nothing more than non-woven fabrics, plain woven fabrics, paper, etc., and choose appropriate materials according to customer needs. No matter which material is selected as the lining, it needs to have a corresponding adhesive to bond the fabric. with lining. Nowadays, the most commonly used gluing methods for non-woven linings include general lining with a flat gluing surface and paste-dot lining with concave-convex gluing surface. Generally, the lining with a flat gluing surface has poor adhesion and feels stiffer, but the manufacturing process is shorter, and the cost of mass production is lower; Secondary processing costs more. Providing garment interlinings with good adhesion, adjustable hand feeling according to customer needs, and low cost can n...

Problems solved by technology

[0003] After the existing non-woven lining is glued, the rubber powder is easy to fall into the gaps between the fibers, and the rubber powder is flat, so it is not easy to penetrate into the clothing fibers and affect the adhesion; and the subsequent coiling and cutting of the non-woven fabric It is easy to degumming and lose viscosity during the operation and production process
