Anti-wrinkle treatment of cotton fabric
Cotton fiber is a long history of fiber, it has many excellent wearing performance, such as most of the soft, comfortable, breathable, hygroscopic and so on, so by the people of all ages. However, cotton fabrics also have some disadvantages such as poor elasticity, easy wrinkling, easy shrinkage, easy invasion by microorganisms, mildew and brittleness of the fibers, wrinkles during wearing and washing process, inability to maintain a smooth appearance, frequent ironing Hot, so to people's lives has brought a lot of inconvenience. In recent years, with the improvement of people's living standard and the enhancement of environmental protection and health awareness, people increasingly like to wear clothes made of natural fibers. In order to overcome the wrinkle of cotton clothes during wearing and the need to iron after washing Defects, anti-wrinkle cotton fabric finishing has become extremely important finishing process. Most of the anti-crease finishing agents currently used are 2D resins, however, the fabrics after 2D resin finishing release formaldehyde during use and storage, endangering people's health. With the increasing awareness of environmental protection and health, people pay more and more attention to the problem of formaldehyde on cotton fabrics and more and more to formaldehyde-free finishing agents. Therefore, the traditional anti-wrinkle finishing agents are greatly challenged.
Since 1926, the United Kingdom applied for the first fabric wrinkle shrink-proof finishing patent has been for more than half a century, experienced during the fabric-free finishing several stages.
1, anti-wrinkle anti-wrinkle finishing
As early as 1928, Foulds.R.P. Et al on the use of water-soluble urea-formaldehyde, phenolic resin treatment of cotton fabric to improve its anti-wrinkle properties. Due to the thermosetting pre-shrinking resin used at the time, it was unable to enter the interior of the fiber, leaving only the surface resin deposited between the fiber and the fiber, so the feel was poor. Originally applied only to viscose fibers, by the 1940s reactive resin finishes such as melamine / aldehydes and epichloroethylene / aldehydes were synthesized, mainly for cotton fabrics. As the main purpose of anti-wrinkle anti-wrinkle finishing fabric to improve dry wrinkle resistance, although it can make clothes not easy to wrinkle when worn, but the fabric wet wrinkle resistance did not improve significantly after washing there are obvious wrinkles, and still Need to be ironed
2, wash can wear finishing
From the 1950s to the 1960s, chemical fibers developed rapidly and quickly occupied the market with the advantages of smoothness, quick drying, dimensional stability and good fastness. Natural fiber once entered the trough. In order to contend with the chemical fiber, the anti-crease finishing stage characterized by improving and improving the wet resilience of the natural fiber fabric was entered. That is, the finishing effect did not disappear due to washing, After wearing and washing still has good anti-wrinkle properties, do not need to iron, this finishing called wash and wear finishing (Wash and Wear).
3, durable pressing finishing
In the mid-1960s, durable press finishing, DP (Durable Press) finishing or PP (Permanent Press) finishing, was developed. On the one hand, the level of anti-wrinkle fabric than the wash can be put through the finishing stage has improved, that is, the appearance of smooth wrinkle, the size and stability; the other hand, the fabric also has the effect of maintaining the shape of the garment and pleated set, Pleats remain unchanged. However, due to the strong decline in strength after the treatment of pure cotton fabrics, in fact, this period of durable pressure finishing is mainly used in polyester-cotton blended fabrics.
4, low formaldehyde finishing
With the improvement and improvement of wrinkle resistance, other physical and mechanical properties of cotton fabrics are affected, such as strong decline, wear resistance, feel and hygroscopicity are also varying degrees of deterioration, so to the 1970s, a major anti-crease finishing The goal is to improve the flexibility and strong retention of finished fabrics. Another focus of development is to reduce the amount of fabric formaldehyde emissions to reduce the human body irritation and harm, known as low-formaldehyde finishing or less formaldehyde finishing. In the methylol type finishing agent used formaldehyde as a raw material, formaldehyde is an irritant, it is irritating to human mucous membranes and skin, can cause respiratory inflammation and dermatitis. On the other hand, formaldehyde is a toxic substance that is harmful to the protoplasm of biological cells, binds to proteins in living organisms, alters the protein structure and coagulates it, causing tissue lesions that may be a carcinogen. In recognition of the harmful effects of formaldehyde on the human body, all countries have introduced relevant laws and regulations or mandatory standards to strictly limit the free formaldehyde content of products. In view of this situation, various products and processes aimed at reducing formaldehyde emission have been developed in the field of textile dyeing and finishing production and research.
5, formaldehyde-free finishing
Since the 20th century 80 years, with the environmental protection and the growing green wave of ecology, proposed to eliminate formaldehyde requirements, formaldehyde-free finishing agent came into being. The emergence and development of polycarboxylic acid finishing agent is a major breakthrough, because it fundamentally changed the line followed by nearly a century of ether-based crosslinking system instead of esterification crosslinking system. Of course, formaldehyde-free finishing agents already have, such as epoxy resin, sulfur compounds, glyoxal resin. As far as polybasic acids are concerned, they were also studied as far back as the 1960s. However, there are still no strict requirements on the restriction of formaldehyde in the society. These finishing agents do not have the motivation for development and growth. In addition, Did not form a climate.
Anti-wrinkle anti-crease and anti-ironing technology adopted by anti-wrinkle anti-ironing fabric in Xinxiang Yulong Textile Co., Ltd. The fabric is super stable liquid ammonia product. It is a special imported anti-crease finishing fabric after liquid ammonia processing, The most perfect finishing experience ever.
Has the following characteristics:
1, with excellent long-term anti-shrinkage properties, Tsukamoto almost no shrinkage after washing.
2, greatly increased the flexibility of the fabric, no ironing after washing, smoothness up to 3.5 or more.
3, bright shiny fabric surface, thin fabric like silk.
4, feel soft and smooth, washed many times, always maintain a new soft natural style.
5, a special anti-wrinkle finishing agent to make the fabric non-destructive and excellent moisture absorption.
