Problems solved by technology

[0002] With the development of economy and society and the improvement of people's quality of life, natural fiber clothing such as cotton, linen, tencel and other breathable and moisture-permeable textiles that are comfortable to wear have received more and more attention and love from people. The shrinkage rate is large, the wrinkles are serious, storage and ironing are troublesome, and oil stains are difficult to remove. Therefore, it is necessary to develop the waterproof, oil-proof, stain-proof, and non-ironing technology of this kind of clothing, that is, "three preventions and one exemption". Improve the effect
Although there are many technical reports on this aspect at home and abroad, the amount of resin and three-proofing agent used in the finishing solution for soaking clothes is relatively large. In addition to the large consumption of raw materials, the effect is not very satisfactory, and the pollution discharge is large, not environmentally friendly, and Both are completed by a two-step method, which prolongs the time of the production process and increases the production cost

Embodiment 1

[0026] Take the polyester / cotton dark twill lining cloth and perform the following finishing process:

[0027] Pad resin water repellent (fluid rate 75%) → pre-drying → tentering drying, control the moisture content of 12% when dropping cloth) → friction calendering → wet stacking → baking (170℃, 5min) →Soaping→Water washing→Neutralization→Padding anti-wrinkle finishing liquid→rolling and outsourcing plastic film→room temperature stacking→relaxing→leaving for 6h→water washing→drying;

[0028] The composition of the resin water repellent finishing agent solution is as follows:

[0029] Melamine resin CHD4g / L

[0030] Catalyst 3g / L

[0031] Silicone waterproofing agent emulsion 6g / L

[0032] The pre-drying adopts heat to dry at 80°C to reduce the moisture content of the fabric to below 30%;

[0033] The stenter drying is performed on a heat distribution clip stenter;

[0034] The friction calendering process is carried out twice in sequence. The composition of the rollers is 2 soft rollers,...

Embodiment 2

[0043] Take the polyester / cotton dark twill lining cloth and perform the following finishing process

[0044] Dipping resin water repellent (fluid rate 85%) → pre-drying → tentering drying (controlling moisture content of 16% when dropping cloth) → friction calendering → wet stacking → baking (180°C, 4min) →Soaping→Water washing→Neutralization→Padding anti-wrinkle finishing liquid→rolling and outsourcing plastic film→room temperature stacking→relaxing→leaving for 8h→water washing→drying;

[0045] Wherein, the composition of the resin water repellent finishing agent solution:

[0046] Melamine resin CHD4g / L

[0047] Catalyst 6g / L

[0048] Water and oil repellent emulsion 4g / L

[0049] The pre-drying adopts heat separation or infrared ray drying at 100°C to reduce the moisture content of the fabric to below 30%;

[0050] The stenter drying is performed on a hot-air pin stenter;

[0051] The friction calendering process is carried out twice in sequence. The composition of the rollers is 2 so...

Abstract

The invention relates to a durable waterproof crease-resistant finishing method for a polyester / cotton dark color twilled lining fabric. The method comprises the following steps: padding a resin water repellent with the mangle expression of 75-85 percent, preliminary drying, tenter drying (the moisture content is controlled to be 12-16 percent during cropping), rubbing and calendering, wet stacking, roasting at the temperature of 170-180 DEG C for 4-5 minutes, soaping, washing, neutralizing, padding in crease-resistant finishing solution, rolling and externally packing a plastic film, stacking at room temperature, loosening, standing for 6-8 hours, washing and drying. The working solution is prepared by adopting a melamine resin CHD, a catalyst, organosilicon waterproofing agent emulsion (or water and oil repellent emulsion). The finished fabric can have long-lasting high glossiness, excellent waterproof performance and high crease resistance.
