Technical Field

The invention relates to the field of non-ironing clothes, in particular to a method for easily decontaminating formaldehyde-free non-ironing clothes.

The invention relates to the field of non-ironing clothes, in particular to a ready-made clothes easy to clean and free of formaldehyde.

Background

The shirt ironing-free finishing is a perfect ironing-free process in the domestic market at present, the modified glyoxal resin adopted is matched with a catalyst to enable adjacent molecular structure hydroxyl groups of the cellulose fibers to be linked with multifunctional groups of the resin, the intermolecular structure is remolded, the intermolecular structure becomes relatively stable, and the original shape of the fabric can be quickly restored after the fabric is deformed after washing, namely the basic principle of the ironing-free process.

The easy-care shirt is a shirt which can still meet the requirements of smooth appearance and smooth appearance of seams after being washed and dried. The easy-care shirt has the performance that after being washed for many times, the easy-care shirt can be restored to a state suitable for wearing or using without ironing or only needing slight ironing. At present, the non-ironing finishing of shirts mostly adopts high polymer materials, and mainly adopts synthetic resin as an anti-wrinkle finishing agent. The polymer is added with other components of synthetic resin, and the effects of crease resistance, shrinkage resistance, water repellency, easy washing, hand feeling improvement and the like are achieved. However, the biggest problem of the shirt finished by the synthetic resin easy-care finishing is that the residual formaldehyde exceeds the standard.

Formaldehyde is an irritant chemical, which can irritate the respiratory tract and skin of the human body, is a significant trigger of allergy, and can also induce cancer. The formaldehyde is closely related to the non-ironing finishing of the shirt, and no matter the finishing agent contains formaldehyde or low formaldehyde, after the non-ironing finishing, a certain amount of formaldehyde is comprehensively remained on the non-ironing product. Today, the formation of the green consumption concept of consumers and the enhancement of environmental protection consciousness, toxic and harmful substances in clothes are reduced as much as possible, safe, healthy and environment-friendly products are provided for consumers, and the key point of work is provided.

It has also been shown in recent market research that glyoxal resins release aqueous free formaldehyde during the crosslinking reaction. The problem that formaldehyde of part of non-ironing products exceeds standard is obvious, and most manufacturers try to reduce the content of free formaldehyde through process improvement. In addition, various body fluids excreted by human bodies, body fat wastes are adsorbed on the fabric in the wearing process, and various water-soluble stains, oil stains and the like are carelessly stained in life. The water in washing is not easy to permeate into fiber gaps, and the fabric has lipophilicity, so that dirt is difficult to remove. And is easily re-smeared onto the fabric. Due to the remolding of the molecular structure after resin finishing, the wet dirt-sticking property of the fabric surface is enhanced, so that the water-soluble and oily dirt is easy to stain the fabric. In the present day that green consumption has become the consumption trend of the new century, the problem of harmful substance residue in the clothes is taken into account, and the green clothes meeting the safety requirements are provided for consumers.
