The working principle of the bleacher is adding or removing oxygen from the fabrics to remove stubborn stains: protein-based stains, tannin stains, and dye-based stains, so as to whiten the clothes. For laundry workers, comprehensively knowing the concepts of bleaching can help them determine the safety degree of different bleachers for colored fabrics, and using bleachers correctly is also the key to protecting the fabrics.<\/p>\n<p>The high temperature plays a role as a driver in the bleaching process. The research shows that every time the temperature rises 5.6\u2103, the chemical effect of the bleacher will double. Take 32.2\u2103 to 37.8\u2103 as an example, the chemical effect directly doubles, and the bleaching effect also increases greatly. However, the special chemical properties of bleachers also contain many risks.

It is composed of two parts of hydrogen and two parts of oxygen. The excess oxygen is exactly the key to safe bleaching. However, many laundry shops mixed hydrogen peroxide with ammonia or protein-based formulations to speed up the bleaching process. This combination will make the erosiveness of the bleacher intensify. The addition of the alkali may also lead to a color change in the colored fabrics.<\/p>\n<p><strong><b>The Suggested Solution<\/b><\/strong><\/p>\n<p>If people want to use the 3% hydrogen peroxide safely, the spray bottle should be used to achieve partial treatment.

If the stains are stubborn, multiple sprays should be done. Although it takes time for the hydrogen peroxide to realize its chemical effect, the laundry workers can do other tasks during this period. The biggest advantage of hydrogen peroxide is that it can be dissolved comprehensively into water after the <a href=\"https:\/\/youtu.be\/Xc-4NVyO91o?si=G7KBJ5fCH6MM5koQ\"><strong><u><b>drying<\/b><\/u><\/strong><\/a>\u00a0process without additional rinsing or neutralization, which is relatively convenient.<\/p>","protected":false},"excerpt":{"rendered":"<p>In the daily work of the laundry shop, the bleaching treatment is a common way of removing stains on shallow [&hellip;]<\/p>","protected":false},"author":1,"featured_media":3493,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[28],"tags":[],"class_list":["post-3467","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/posts\/3467","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/comments?post=3467"}],"version-history":[{"count":2,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/posts\/3467\/revisions"}],"predecessor-version":[{"id":3471,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/posts\/3467\/revisions\/3471"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/media\/3493"}],"wp:attachment":[{"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/media?parent=3467"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/categories?post=3467"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/kingstarlaundry.com\/es\/wp-json\/wp\/v2\/tags?post=3467"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
