Abstract

A method for producing a formaldehyde-free easy-care shirt, comprising the following production steps in sequence: shirt sewing, washing, drying, spraying of a formaldehyde-free easy-care finishing liquid, pre-drying, pre-ironing, pressing, baking, freezing, washing of a finished product, drying of the finished product, and packing of the finished product. By spraying the formaldehyde-free easy-care finishing liquid, a pick-up of the skirt reaches 65-90%; the formaldehyde-free easy-care finishing liquid consists of the following components: easy-care resin, a fiber protective agent, a softening agent, a catalyst, and water; the temperature of the pre-drying is 40-60°C, and the pick-up of the pre-dried skirt reaches 20-50%; the temperature of the baking is 140-160°C and the duration is 3-7 minutes; the temperature of the freezing is -10°C to 0°C, the freezing duration is 0.5-1.5 hours, and the humidity of a freezing chamber is 60-90%. By means of the method, no formaldehyde is generated in the entire skirt production process, and the finished easy-care skirt product thus contains no formaldehyde residue.

Description

[Name of invention made by ISA according to Rule 37.2] Production method of formaldehyde-free ironing shirt

Technical field

The invention relates to a method for producing a shirt, in particular to a method for producing a formaldehyde-free ironing shirt.

Background technique

At present, the production process steps of the ironing-free shirt are in turn, shirt sewing, water washing, drying, spraying non-iron finishing liquid, pre-baking, pressing, shaping, finished product washing, finished product drying and finished product packaging, because in the non-iron finishing liquid Containing aldehyde groups, formaldehyde is produced during the preparation of non-iron shirts, which has an impact on the production environment and makes the finished shirt contain formaldehyde, which has an adverse effect on human skin when worn.

Summary of the invention

It is an object of the present invention to provide a method for producing a formaldehyde-free ironing shirt which is free of formaldehyde during the production of the shirt and which does not contain formaldehyde in the finished ironing shirt.

The technical content of the invention is a method for producing a formaldehyde-free ironing shirt, characterized in that the production steps are sequentially sewing, washing, drying, spraying formaldehyde-free finishing liquid, pre-baking, pre-scalding, pressing , baking, freezing, finished product washing, finished product drying and finished product packaging;

Spraying formaldehyde-free and non-iron finishing liquid for atomizing spraying of formaldehyde-free finishing liquid on the shirt, ensuring that each part of the clothes is sprayed with formaldehyde-free finishing, so that the liquid carrying rate of the shirt reaches 65-90%. The composition of the formaldehyde-free and non-iron finishing liquid is composed of non-ironing resin, fiber protective agent, softener, catalyst and water. The concentration of the non-ironing resin in the formaldehyde-free finishing solution is 150-240 g/L, and the fiber protective agent The concentration in the formaldehyde-free finishing solution is 30-50 g/L, the concentration of the softener in the formaldehyde-free finishing solution is 20-60 g/L, and the concentration of the catalyst in the formaldehyde-free finishing solution is 15~ 35g/L;

The pre-baking temperature is 40-60 ° C, and the liquid carrying rate of the shirt after pre-baking reaches 20-50%;

Baking is to make the non-ironing resin cross-link with the fiber to achieve the anti-wrinkle and anti-scalding effect, the baking temperature is 140-160 ° C, and the time is 3-7 minutes;

Freezing is to freeze the baked shirt in a freezer, the freezing temperature is -10 ~ 0 ° C, the freezing time is 0.5 ~ 1.5 hours, the freezing chamber humidity is 60 ~ 90%, the cellulose fiber of the shirt is baked In the high-temperature environment of baking, it is easy to become uneven, and the surface is easy to be embossed. Because the freezing temperature is low, the ambient humidity during freezing is relatively high, and the humidity of the shirt which is baked at a high temperature is given, so that the moisture regain rate is further increased. The improvement makes the breakage and tearing of the shirt fabric improved, and the hand feel is smoother. The rapid freezing can stop the reaction of the finishing liquid, and the cotton fabric can be instantly restored to a flat surface to achieve a better appearance.

In the above-mentioned production method of the formaldehyde-free ironing shirt, the non-ironing resin in the formaldehyde-free non-iron finishing liquid is Germany. Arkofix NZK of CLARIANT, protorez ffo of tanatex of the Netherlands, KNITEX FF of HUNTSMAN of the United States, REECELZF of BOZZETTO of Italy or FixapretNF of BASF of Germany;

The fiber protectant is Ceranine HDP. of CLARIANT, Germany, persoftal pe25 of tanatex of the Netherlands, WELLIN PE of BOZZETTO of Italy or Perapret additive peb of BASF of Germany;

The softener is Solusoft MW or SE1 of CLARIANT, Germany, persoftal sme of tanatex of the Netherlands, DICRYLAN WK of HUNTSMAN of the United States, SEBOSAN SNC of BOZZETTO of Italy or Sliligen sih of BASF of Germany;

The catalyst is Catalyst NKC of CLARIANT, Germany, KNITEX MO of HUNTSMAN, USA, CATAL MCA of BOZZETTO of Italy or Fixapret f-m of BASF of Germany.

In the above-mentioned production method of the formaldehyde-free ironing shirt, the shirt sewing, washing, drying, pre-scalding, pressing, product washing, finished product drying and finished product packaging are all conventional processes, wherein the water washing is for the shirt to be sewn. Washing and washing away the impurities remaining in the production process; drying to dry the shirt after washing at 60 ° C to dry; pre-hot to make the clothes into a prototype, to improve the subsequent production efficiency, but also repair the production of garments Pressing; pressing to press all parts of the shirt, time and temperature, pressure according to the fabric and shirt parts, the conventional pressing pressure is 3 ~ 5Kg, pressing temperature 90 ~ 150 ° C, pressing time 15 ~ 35 seconds The finished product is washed to remove the chemical substances remaining in the production process to further improve the hand feeling; the finished product is dried and the dried shirt is dried to 60 ° C to dry.

The invention has the advantages that the formaldehyde-free ironing shirt produced by the invention has good hydrophilicity, moisture absorption and gas permeability; at the same time, no formaldehyde is generated in the whole shirt production process, and the finished ironing-free shirt does not contain formaldehyde, and the finished product The heat loss of non-iron shirts is less than half that of ordinary garments.
