Description
Technical Field
The invention relates to the technical field of garment processing, in particular to a method for manufacturing all-cotton high-count non-ironing clothes.
Background
All-cotton easy-care clothes are more and more favored by consumers due to the advantages of comfort, easy care and the like. The existing non-ironing clothes are low in yarn count, such as 40/2, 60/2 and the like. High count fabrics, such as 80/2, 100/2, etc., make shirts that are soft and fine, fine to make, and very comfortable to wear. The high yarn count fabric is easy to wrinkle, and has high requirements on indexes such as combing property, tearing strength and the like, so that the fabric is required to be subjected to crease-resistant treatment.
Most of the existing anti-wrinkle technologies are used for treating ready-made clothes, and during the continuous washing and ironing process, radial shrinkage of stitches at seams of the clothes is easily caused, the shrinkage is much larger than that of surrounding fabrics, so that wrinkles and retraction at the seams of two pieces of clothes are caused, and even if the clothes are subjected to hot pressing and curing and shaping after being baked, the wrinkles are recovered after being washed with water, and the attractiveness of the ready-made clothes is affected.
Chinese patent CN107183816A discloses a pure cotton high count yarn clothing seam setting technology, which introduces cellulose reaction type strip-shaped bonding substrate at each seam and combines the hot press setting and the solidification setting to carry out crease-resistant treatment on the clothing during the clothing manufacturing process, although there is a certain effect, the clothing is inferior in softness and smoothness, and the whole comfort is inferior.
In addition, pure cotton casual pants are all washing products, common woven fabrics can be subjected to desizing treatment during dyeing or printing, but casual pants cloth and jeans are directly woven after yarn dyeing, and the process of cloth dyeing or printing is omitted, so that finished products are not subjected to desizing treatment and can only be subjected to desizing during washing of the products. Then the finished leisure pants are subjected to washing water treatment in a washing water plant in order to pursue different effects and unique handfeel. That is, the washing water is removed after cutting and sewing, but wrinkles are easily generated when the fabric is worn after washing due to the characteristics of pure cotton, and the comfort is reduced.
In a word, the comfort of the high yarn count non-ironing clothes treated by the existing anti-wrinkle technology is poor.
Disclosure of Invention
The invention aims to: aiming at the problems that a high yarn count fabric in the prior art is easy to wrinkle and the comfort of high yarn count non-ironing clothes treated by the existing anti-wrinkle technology is poor, a manufacturing method of all-cotton high yarn count non-ironing clothes is provided. According to the method, the clothes can be rapidly cooled by baking and then freezing the clothes, the quick freezing effect is enhanced, the contractility of cloth fibers is stronger, the clothes are softened by washing, the softness and the smoothness of the clothes are enhanced, the clothes are enabled to have good crease resistance integrally, and the wearing comfort is enhanced.
In order to achieve the purpose, the invention adopts the technical scheme that:

b, performing first washing treatment on the clothes obtained in the step A, and then spraying non-ironing finishing liquid to the clothes;
c, drying the clothes obtained in the step B for the first time, and then pressing the bones;
d, baking the clothes obtained in the step C, and then performing quick cold air freezing treatment;
and E, performing secondary washing treatment on the clothes obtained in the step D, then performing secondary drying treatment, and performing ironing to obtain finished products of the non-ironing clothes.
The durable crease-resistant performance of the clothes is improved by washing the clothes with water and spraying the non-ironing finishing liquid. On the basis, the clothes to be baked are quickly frozen, the temperature is quickly reduced by 140-170 ℃, so that the cotton fiber has stronger contractility, and the anti-wrinkle performance is further improved; after washing, the friction coefficient among the cotton fibers is reduced, the softness and the smoothness of the clothes are obviously improved, and the non-ironing clothes have good crease resistance and comfort.
As a preferable scheme of the invention, in the step B, the weight ratio of the non-ironing finishing liquid to the clothes is 2: 3-1: 1; the pH value of the non-ironing finishing liquid is 4.5-5.5; the easy-care finishing liquid comprises the following components in parts by weight,
180-195 parts of non-ironing resin; 35-40 parts of a catalyst; 40-45 parts of a fiber protective agent; 40-45 parts of a softening agent; . The non-ironing finishing liquid also comprises 5-50 parts of water by weight. The amount of water can enable the pH value of the easy-care finishing liquid to be 4.5-5.5.
