Embodiment 1

[0042] Embodiment 1, a kind of shirt environmental protection non-ironing process, comprises the following steps:

[0043] Step 1, finishing agent absorption: dissolve the finishing agent and water at a ratio of 1:3, and spray the finishing agent solution evenly on the shirt through the atomizing nozzle;

[0044] Step 2, preliminary drying: put the shirt absorbed with the finishing agent solution into an oven for drying, the drying temperature of the oven is 60-70°C, and dry the shirt until the finishing agent solution does not drip;

[0045] Step 3, three-dimensional shaping: press and shape each part of the shirt at a temperature of 130-150°C until the shirt has a good appearance;

[0046] Step 4, shaping in the drying room: Hang the pressed shirt on a hanger made of heat-resistant material, and put it in the drying room to completely dry the shirt and complete the setting. The drying temperature of the drying room is 160-180°C , the drying time is 4-5min;

[0047] Step 5,...

Embodiment 2

[0049] The difference between Example 2 and Example 1 is that, in parts by weight, the raw material components of the finishing agent are shown in Table 1.

Embodiment 3

[0050] The difference between Example 3 and Example 1 is that, in parts by weight, the raw material components of the finishing agent are shown in Table 1.

Abstract

The invention discloses an environment-friendly non-ironing process for a shirt, relating to the technical field of garment processing. The process comprises the following steps: (1) finishing agent absorption; (2) primary drying; (3) stereoscopic molding; (4) drying room shaping; and (5) washing and drying, wherein a finishing agent contains the following raw materials in parts by weight: 20-35 parts of BTCA and 1-2 parts of sodium hypophosphite. The process has the beneficial effects that BTCA has good esterification reaction activity, two adjacent carboxyl groups are dehydrated at a high temperature to form cyclic dianhydride during the primary drying and the drying room shaping, cyclic anhydride has very high reaction activity, the surfaces of fibers of the shirt contain hydroxy, cyclic anhydride can generate ester with hydroxy under the catalysis of sodium hypophosphite so as to form an esterified cross-linking system, so that the shirt has a good wrinkle removal effect. The shirtprocessed by virtue of the process does not contain formaldehyde and is environment-friendly, and the production cost can be effectively lowered. Sodium hypophosphite has reducibility and is capableof bleaching the shirt.

Description

technical field [0001] The invention relates to the technical field of garment processing, and more specifically relates to an environmentally friendly and non-ironing process for shirts. Background technique [0002] Non-iron shirts are defined as those that can be returned to wearing or using condition after home washing with light or no ironing, and have wrinkle-resistant and shrink-resistant effects. [0003] In the prior art, non-ironing shirts are mainly treated with a resin finishing agent in the post-finishing process to improve the anti-wrinkle and anti-shrinkage effect of its products. But the resin finishing agent usually contains a certain amount of formaldehyde, which will release formaldehyde during storage and wearing in the warehouse, which will affect the health of the wearers and cause certain pollution to the environment. [0004] The Chinese patent with the notification number CN101666037B discloses a method for removing formaldehyde in non-ironing shirt...
