Abstract

The invention discloses a low-temperature pressing washable pure cotton woven adhesive interlining and a production method thereof. The production process comprises the steps of seam turning, singeing, refining, bleaching, chemical shrink-proof finishing, coating and mechanical pre-shrinking. During chemical shrink-proof finishing, formaldehyde-free butane tetracarboxylic acid is adopted as a finishing agent. During coating, a mixed hot melt adhesive of low-density high-pressure polyethylene and high-density high-pressure polyethylene is adopted. The method is energy-saving and convenient to operate, can be suitable for more fabrics which are not resistant to high temperature, and can avoid the defects of fabric strength reduction, hardening and yellowing, fabric style change and the likecaused by high-temperature pressing. The product is excellent in performance, the pressing temperature is 140-150 DEG C, and the product is washable; no formaldehyde is contained; and the warp and weft washing dimensional change rate is -1.0% to +0.5%.

Description

Technical field [0001] The present invention relates to the field of adhesion lining, and more particularly to a low-temperature pressure-resistant water-washing cotton woven, bonding liner, and its production methods. Background technique [0002] The adhesive lining means that the woven fabric, knitted fabric, nonwoven fabric, etc. are the base fabric, and the hot melt polymer compound, that is, hot melt glue, special machining, specially mechanically, can be bonded to clothing sheets. The properties of the adhesive lining and the conditions of the pressure, pressure, and time, to a large extent, and the performance of hot melt glue is largely determined. Different kinds of hot melt adhesive have different physical chemical properties, even with the same type of hot melt glue, it also forms a series of products with different properties due to their components. Due to cost, etc., currently, the cotton woven woven lining used in the shirt linen is currently used in the market, a...
