Description

The method of soybean fiber fabric lousiness-pilling-resistance finishing
Technical field
The present invention relates to a kind of method, belong to the textile dyeing and finishing technical field soybean fiber fabric lousiness-pilling-resistance finishing.
Background technology
Fibre and soya is a kind of new Regenerated Protein Fiber of Chinese science and technology personnel independent development, is formed through wet spinning by soybean protein and polyvinyl alcohol mixing liquid, has passed through the acetalation crosslinking Treatment in the back road processing of spinning.Fibre and soya can or interweave with conventional textile raw material blending such as wool, cashmere, silk, viscose glue, bamboo fibre, day silk, model, terylene, polyamide fibre.Moisture absorption is good, soft, gloss is soft, take good characteristics such as comfortable because fibre and soya has, and therefore, is used for development of new garment material and household textiles by textile industry, and is wherein in the majority with blended union class knit product.
At present, the fibre and soya product mainly is the staple fibre that is cut into certain-length, its surface is very smooth, frictional coefficient of fiber is little, fiber crimp is few, and cohesive force is little, and fibre and soya is very easily outwards slippage from yarn under external force, therefore, easily fluffing, the young pilose antler of generation continue wear in tied up in knots mutually just, rubbed into many spherical granules.The ball top of fabric face is very easily attached by dirt, dust, make fabric wear performance and outward appearance is had a strong impact on.
The factor that influences the fibre pick balling-up is a lot, generally can improve the anti-fluffing and anti-pilling performance of fabric by specification, fabric structure and the improvement dyeing and finishing technology condition of regulating yarn.For example, the yarn that the twist is high, interfibrous obvolvent is tight, and outstanding fiber can reduce, and has reduced the mobility of fiber, and yarn is when being subjected to rubbing, and fiber slippage in the yarn is relatively just few, and the pilling phenomenon will reduce; From fabric structure, hard-packed tissue is difficult for pilling than loose tissue, and the fabric that cloth cover is more smooth, smooth is difficult for pilling than the rough fabric of cloth cover; When pre-treatment and dyeing, add lubricant and can prevent friction, reduce the generation of balling-up.But, prevent the pilling of fabric in the process of taking, then should carry out anti-pilling finishing.
At present, the method for fabric anti-fluffing anti-pilling mainly contains biopolishing and RESIN FINISH method.Biopolishing is that profit has biology enzyme that fabric is carried out biopolishing, utilizes the hydrolysis of enzyme and the percussion of machinery jointly to remove the surperficial young pilose antler and the tip of fiber.The utilization biopolishing has obviously reduced pilling trend, and effect is lasting, even after repeating to wash in the family expenses washing machine, the fabric of biopolishing relatively still keeps no young pilose antler.But this method is mainly used in the anti-fluffing and anti-pilling of wool fabric and handles, but the polypeptide chain of specific protease catalytic decomposition wool fibre, thus removed the young pilose antler of fabric face and the tip of fiber, reach the anti-fluffing and anti-pilling effect.Because fibre and soya is a kind of novel fiber, also do not have at present to be developed at the biology enzyme of soybean fiber, therefore, can not adopt the biopolishing technology to carry out anti-pilling finishing.The RESIN FINISH method is to utilize the function of resin in the netted film forming of fiber surface interlinkage, makes the wear-resisting resin molding of fiber surface parcel one deck, and this resin molding weakens the slippage of fiber; Simultaneously, resin interlinkage equably condenses upon the top layer of yarn, and fibre end is adhered on the yarn, is difficult for pilling during friction, thereby can improves the pilling resistance of fabric effectively.Existing anti-pilling finishing agent and processing method are mainly used in wool, acrylic fibers, terylene short fiber BLENDED FABRIC etc., and this method need bake processing under hot conditions.And lower, the poor heat resistance of soybean fiber reactivity, xeothermic easily yellowing more than 120 ℃, powerful decline, fabric feeling hardens, and existing method can not be used for the arrangement of soybean fiber.And the general at present anti-pilling finishing agent that uses contains a certain amount of formaldehyde, does not meet the requirement of ecological textile, and feel, style to fabric after handling have bigger influence.
Summary of the invention
The objective of the invention is to overcome deficiency and limitation that prior art exists, provide a kind of effectively, the method for sorting of the soybean fiber fabric lousiness-pilling-resistance of environment-friendly type.
