Abstract
The invention discloses a kind of quick upper dyeing methods of superfine fibre suede, include the following steps: to immerse superfine fiber chemical leather in treatment fluid, pad, dry after padding, the woven fabric suede after drying is dyed；The treatment fluid includes the component of following parts by weight: 8-20 parts of aqueous polyurethane, 0.3-0.5 parts of dispersing agent, 0.5-1.5 parts of anti-settling agent, 0.2-1 parts of defoaming agent, 100 parts of deionized water.The present invention is since aqueous polyurethane particle enters in the gap of superfine fibre, and uniformly, dye level, color homogeneity and dry fastness, fastness to wet rubbing all increase upper dye in subsequent dyeing.The present invention solves in superfine fibre suede normal dyeing in the prior art the problem of fastness to wet rubbing is low, dyeing dyeing defect, dark color easily fades.
Description
Technical field
The present invention relates to the quick upper dyeing methods of superfine fibre suede.
Background technique
Superfine fiber chemical leather is the third generation rtificial leather after PVC, PU, it is to use and the island natural leather Zhong Ding
Similar 6 superfine fibre of polyamide fibre of the structure and performance of collagenous fibres, is made the high-density non-woven fabrics with tridimensional network, then
The excellent polyurethane with open type microcellular structure of filling capacity, made of being handled through post-processing.This synthetic leather is super with island is determined
The intrinsic hygroscopicity of thin collagenous fibres natural leather.Thus, it is either special from internal microstructure or appearance tactile impression, physics
Property and snugness of fit etc., can compare favourably with advanced natural leather.In addition, superfine fiber chemical leather is in chemically-resistant
Property, mass uniformity, production and processing adaptability and waterproof anti-mildew etc. be better than natural leather, to make case
Packet, clothes, shoes and automobile interior decoration etc. have vast potential for future development.
Superfine fiber chemical leather is made of 6 fiber of ultra-fine nylon and polyurethane two parts.Polyamide fibre 6 is polyamide structure, point
Containing end amido in minor structure, can be dyed by acid dyes, neutral dye and reactive dye for wool.But 6 fiber of ultra-fine nylon
Thinner than general fibre more, large specific surface area, so there are a series of problems in dyeing, as dyeing rate is too fast, colour rendering
Difference and dyefastness difference etc..The primary chemical composition of polyurethane is polyurethanes, it is by soft chain segment and hard segment group
At block copolymer.Using acid dyeing, the dyefastness of product is poor, and using neutral dyeing, there is a huge sum of moneys
The problem of belonging to (such as Co, Cr) pollution.
Summary of the invention
The object of the present invention is to provide a kind of quick upper dyeing methods of superfine fibre suede, to overcome the prior art to exist
Defect.
Method of the invention, includes the following steps:
Superfine fiber chemical leather is immersed in treatment fluid, is padded, the liquid carrying rate of super fiber leather is 50%~70%；It is dried after padding
It is dry, the woven fabric suede after drying is subjected to normal dyeing.
The treatment fluid includes the component of following parts by weight:
The preparation method is as follows:
It by dispersing agent, anti-settling agent, defoaming agent, is slowly added in deionized water and is uniformly mixed under high speed dispersion, then will
Aqueous polyurethane, which is added thereto, tells emulsification, obtains the treatment fluid；
The aqueous polyurethane is selected from Dongguan meter Ren Zhan Chemical Co., Ltd., and the trade mark is the product of MR-705.
The anti-settling agent is surfactant solution, is selected from Guangzhou Yan Gu trade Co., Ltd, trade mark KYC-426
Product；
The dispersing agent is the copolymer of the affinity groups containing pigment, is selected from Guangzhou Yan Gu trade Co., Ltd, the trade mark
For the product of KYC-9166；
The defoaming agent is non-silicon high molecular polymer, is selected from Guangzhou Yan Gu trade Co., Ltd, trade mark KYC-
750 product；
The preparation method of the superfine fibre suede, woven fabric suede common staining method, for details, reference can be made to documents:
Qu Jianbo, synthetic leather material and technology [M], Beijing, Chemical Industry Press, 2015.9；
The present invention is compared with traditional people's colouring method, since aqueous polyurethane particle enters the gap of superfine fibre
In, uniformly, dye level, color homogeneity and dry fastness, fastness to wet rubbing are all mentioned upper dye in subsequent dyeing
It is high.The present invention solves in superfine fibre suede normal dyeing in the prior art that fastness to wet rubbing is low, dyes dyeing defect, dark
The problem of easily fading.
