Embodiment Construction

[0015] refer to figure 1 For the embodiment of the extra-hard hat liner production technology of the present invention, comprise the following steps successively:

[0016] A. Base fabric weaving: The warp and weft yarns of the woven base fabric are 58Tex×58Tex cotton yarns woven on a rapier loom with 196 pieces / 10cm×157 pieces / 10cm;

[0017] B. Alkali rolling and stacking, oxygen bleaching treatment: pre-treatment is carried out by the gray cloth singeing, light alkali stacking, desizing and compound refining enzyme oxygen bleaching process;

[0018] C. Special hard finishing: polyacrylate latex 20g / L, polyvinyl acetate latex 30g / L, ultra-low formaldehyde resin 80g / L, magnesium chloride 13g / L, whitening agent 9g / L, double dipping and second rolling reduction rate 70 %;

[0019] D. Coating: use low-density polyethylene hot-melt adhesive to process powder dot coating on the powder dot machine;

[0020] E. Baking and calendering: bake and cure the coated interlining and then c...

Abstract

The invention discloses a production process of an ultrahard cap lining, which orderly comprises the following steps of: base cloth weaving, alkali padding and piling, oxygen delignification processing, ultrahard finishing, coating, baking, calendaring, reeling, final detecting, and finished product obtaining. The advantages of the invention are that: the product has hand feel with quite high hardness, a stable dimension, a low shrinkage, and excellent shape retention; the cap lining has high massiness, does not blister or degum after being washed with 90 DEG C water for several times, and has quite bright press polish.

Description

technical field [0001] The invention relates to a production process of an extra hard hat lining. Background technique [0002] my country is a big hat production country and a big exporter. It needs about 2 billion meters of hat linings every year. While people's requirements for hats are constantly improving, the quality requirements for hat linings are also constantly improving, especially for export products. At present, domestic hat linings Generally, the stiffness is not enough, the shape is not good, and the shrinkage rate is relatively large and the sense of thickness is not strong, which seriously affects the grade and price of the hat. Contents of the invention [0003] The purpose of the present invention is to provide a production process for extra-hard hat linings, which can effectively solve the problems that the hat linings generally have insufficient stiffness, poor shape retention, relatively large shrinkage and low thickness. [0004] In order to solve th...
