Discussion On GB/T&Nbsp, 22700 - 2008 Test Standard For Washing And Finishing Garments

Abstract: This article introduces

Key words: water washing finishing; washing and finishing methods; after washing

1 industry background

In recent years, with the development of China's garment manufacturing industry and the continuous improvement of people's living standard, people have more and more emphasized the leisure function and comfortable function of clothing. The style, feel and appearance quality of traditional garments can no longer meet the needs of multi grade and multi-level personalization. The appearance of washing and finishing clothing can make up for the lack of comfortable functions of some garments [1].

In recent years, the washing and finishing types of clothing have developed rapidly. The traditional jacket, shirts, trousers and cotton garments can be washed and cleaned [2], which greatly improves the added value of the products.

But with the rapid development of the industry, the problem of product quality supervision is becoming more and more prominent.

At present, there are no relevant technical standards specifically for washing and finishing garments in China. Other similar product standards can not fully reflect the quality characteristics of such garments, making the quality complaints of such products increasing day by day.

In order to further improve the overall quality level of the products and guide the healthy and orderly development of the industry, it is of great significance to formulate standards for washing and finishing garments.

Under such circumstances, some large garment enterprises in Fujian province (such as nine Mu Wang, Qipai, Jin Ba, etc.) jointly drafted the GB/T22700 - 2008 standard for washing and finishing garments jointly with the Shanghai Clothing Research Institute and Fujian Textile Inspection Institute.

2 water washing finishing method

Washing finishing refers to the finishing process of fabric or clothing after washing or washing, sand washing, enzyme washing, rinsing, snowflake washing, non iron washing, etc., or one combination of water washing processes. [3]

After such treatment, the final garment products will produce partial discoloration, uneven color, natural or obsolete appearance, or some special functions, such as ironing and washing, which will make the garment durable and ironing.

However, there will be some defects in the quality of garments or fabrics after washing.

1) the fabric has obvious fading and poor color fastness, especially wet rubbing fastness [4];

2) the physical properties of fabrics are reduced, especially the tear strength and other physical properties, because finishing will make the brittleness of the finished fabric increase by [5].

3) the appearance quality has obvious characteristics, with many defects and obvious color difference.

Washing and finishing will cause the above defects, so the relevant standards can not be tested according to the requirements of ordinary woven garment standards, but should be lower than other standards to a certain extent, which is the original intention of formulating this standard.
