One is that production enterprises reduce their processes and cut corners during the production process, blindly pursuing appearance effects and disregarding technical requirements

众所周知,在纯棉纺织产品染整加工过程中,为了增加产品的光亮美白效果,生产加工企业要对去除除产品进行漂白丝光增白,使产品具有真丝般的手感和光泽,玻璃般的靓丽和美观,能充分吸引消费者的眼球。然而,在进行漂白丝光增白工艺中,溶液的PH值为9.5~11.0,属碱性溶液。而人体的皮肤是中性或偏弱酸性,如果床上用品的PH值过高或者过低时,就会破坏人体的酸碱平衡,使细菌进入到人体内造成伤害。GB 18401-2003《纺织产品基木技术规范》规定,直接接触人体的产品PH值为4.0~7.5。因此,加工后的产品必须进行酸洗漂洗,使产品的PH值呈中性或弱酸性。而这次检验的产品中无论是新的床上用品毛巾浴巾,还是经过洗涤的产品,PH值大部分都超过了标准要求,有的甚至高达10.5.严重影响了广大消费者的身体健康。


As is well known, in the dyeing and finishing process of pure cotton textile products, in order to increase the brightness and whitening effect of the products, production and processing enterprises need to bleach and whiten the removed products, so that the products have a silk like feel and luster, and a glass like beauty and beauty, which can fully attract the attention of consumers. However, in the process of bleaching, mercerizing, and whitening, the pH value of the solution is 9.5-11.0, which is an alkaline solution. The skin of the human body is neutral or slightly acidic. If the pH value of bedding is too high or too low, it will disrupt the acid-base balance of the human body, causing bacteria to enter the body and cause harm. According to GB 18401-2003 Technical Specification for Textile Products, the pH value of products that come into direct contact with the human body is 4.0-7.5. Therefore, the processed product must be pickled and rinsed to maintain a neutral or weakly acidic pH value. And in this inspection, whether it is new bedding towels, bath towels, or washed products, the pH value of most of them exceeds the standard requirements, some even reaching 10.5, seriously affecting the physical health of consumers.


Secondly, in the washing process, the washing industry uses low quality detergents or even directly uses caustic soda without neutralization treatment, resulting in safety technical indicators exceeding standard requirements


The washing of hotel linen should use fabric detergents. Fabric detergents can be divided into heavy scale detergents, light scale detergents, soap based detergents, enzyme added detergents, pre stain removers, fabric softening conditioners, bleaching disinfectants, detergents, dry cleaning agents, etc. Different textile products should use different detergents. The washing industry should choose a detergent with strong applicability and good washing effect to place a small pillow according to the actual situation, rather than using cheap and low-quality detergents, reducing washing processes, and lowering washing quality as means to reduce costs. We found during spot checks that some washing shops have reduced the number of times they pass through water and the neutralization process in order to save costs, and some even directly use caustic soda to make the fabric yellow, brittle, and hard after washing, with a significant decrease in strength. These are all important reasons for the low washing quality and high pH value of fabrics.


Thirdly, in the quality management of linen, hotels and guesthouses attach importance to external characteristics but underestimate internal quality, value enterprise cost accounting but underestimate washing effects, and even ignore consumer health, unintentionally catering to the speculative behavior of certain production and sales enterprises and the washing industry


At present, there are two major misconceptions in the quality management of linen in most hotels and guesthouses. One reason is that when purchasing linen, only attention is paid to the appearance, color, and so-called high grade of the linen, neglecting the requirements of product safety technical indicators, especially technical indicators related to human health and life safety, such as pH value, formaldehyde content, and odor, resulting in a phenomenon of prioritization in management. Some hotels only request qualification certificates when purchasing products from producers and sellers, without asking about the safety technical indicators of the products. Even if some products have inspection reports, they are often entrusted inspection reports with incomplete inspection items, and the root does not have safety technical indicators inspection results. Secondly, for the removal of fabrics that are not used for recycling, whether it is wooden hotel washing or commissioned washing, management personnel only focus on the cost accounting of washing and ignore the excessive residual amount of washing solution; Only focusing on the cleanliness of the product surface, neglecting safety technical requirements, and even not knowing the requirements for sexual technical indicators. Due to the relaxation of the management of removing linen products in most hotels, producers, sellers, and detergents focus solely on product brightness as their competitive goal. Excessive addition of whitening agents and bleaches, as well as insufficient acid neutralization and water washing, can cause consumers to experience contact dermatitis such as itching, erythema, scars, and papules after coming into contact with these bedding products, and even lead to more serious consequences.
