Embodiment Construction

[0006] The cap tire pretreatment process brushes the cap tire clean with steam to make its surface smooth. At this time, the moisture content of the cap tire is controlled between 10-15%, and the pH value is controlled between 5.5-6.5. The waterproofing principle based on the waterproof finishing process is: the commercially available fabric waterproofing agent PF can react with the amino NH on the wool 3 With chemical bonding reaction, there are hydrophobic long-chain hydrocarbon groups on the tire, which makes the surface of the fabric durable and waterproof. At this time, the hat tire is soaked in the fabric waterproof finishing agent solution, and squeezed through the pressure roller of the sizing machine. Fabric waterproof finishing agent solution formula: 60-100 grams of commercially available waterproofing agent PF, 0.75 grams of magnesium chloride, and 0.5 milliliters of crosslinking agent are contained in 1 liter of aqueous solution. The technical conditions of this ...

Abstract

The present invention relates to a kind of water-proofing wool hat blank and finished hat, its main raw material is wool felt hat blank and water-proofing agent and auxiliary material includes magnesium chloride and cross-linking agent. Its technological process includes hat blank pretreatment, water-proofing finished, drying and baking, etc. Its pretreatment of hat blank includes the steps: steam-brushing and cleaning hat blank, and flattening surface, the moisture content of the hat blank is controlled in 10-15%, and its pH value is controlled in 5.5-6.5. Its water-proofing finish procedureincludes the steps: soaking hat blank in water-proofing finish agent solution and roller-pressing by means of glue applicator. Its water-proofing finish agent formula contains 60-100 of water-proofing agent PF, 0.75g of magnesium chloride.

Description

field of invention [0001] The invention relates to a waterproof wool hat tire and a finished hat. Specifically, the surface of the fabric absorbs a waterproofing agent to achieve waterproofing, and belongs to the technical field of hat making. Background technique [0002] The fabric surface of general wool felt hats does not have waterproof performance, which brings great troubles when people living in rainy areas and countries go out. A high-grade wool felt top hat that has not been waterproofed cannot be used in a humid and light rainy climate, which will lead to a significant reduction in its sales range. Therefore, changing this situation has become a research topic for hat industry technicians. one. Contents of the invention [0003] The purpose of the present invention is to propose a waterproof wool hat tire and finished hat, which absorbs or deposits hydrophobic substances on the fabric, so that the surface of the fabric is not easily wetted by water, but the gap...
