Description
Technical field
The present invention relates to the textiles finishing technique, be specially a kind of employing acrylic resin physical blending modified waterborne polyurethane and do rabbit hair fabric losing fibre preventing finishing agent and losing fibre preventing method for sorting.
Background technology
Rabbit fur fibre is elongated, and smooth surface and be rich in gloss is a kind of wool spinning raw material of preciousness.Rabbit hair textiles quality is slim and graceful, sliding glutinous fluffy, soft, and rabbit hair color is pure white, and dyeing, color matching are had very big adaptability.In addition, because the medullary layer of inflating in the rabbit fur fibre is flourishing, the rabbit hair not only has high hygroscopicity, also has good thermal property.The relevant document of certificate (referring to [1] Xue Jiying. special animal fiber product and processing [M]. Beijing: China Textiles Press, 1998.) to introduce, the warming rate of the rabbit hair is 68.5%, and the warming rate of wool is 63.5%, the hygroscopicity of the rabbit hair also is higher than wool.Therefore to have feel soft, sliding glutinous for rabbit hair fabric, and outward appearance is plentiful, fluffy and wear cosy characteristics.
The rabbit hair is suitable to spin stocking yarn, is used for sweater, scarf, cap and interior clothing trousers etc.Rabbit hair sweater fine hair towers, and other tool style can be kept out the cold, and is again ornament attractive in appearance.In wool spinning product, add a certain proportion of rabbit hair, value-added content of product is significantly improved, at high proportion so that pure rabbit hair textiles have more luxurious rich and honour sense.Society progressively enlarges the demand of rabbit hair product in recent years, and the rabbit hair product that occurs on the domestic and international market is of a great variety, comprises knit product, woolen fabrics and spun yarn product etc.Yet because the restriction of character of rabbit fur fibre own and processing conditions, the problem that rabbit hair textiles is prone to hair is effectively solved always, and has greatly restricted the development of rabbit hair textile industry.
The surperficial scale of rabbit fur fibre is single watt of shape slanted bar line, the shell of similar bamboo shoots, and scale is acute triangle, and subtended angle is minimum, makes fiber surface smooth, and is little along reverse coefficient of friction, and curling of rabbit fur fibre is also few than wool.These factors cause interfibrous cohesive force in the rabbit hair fabric, frictional force little, and fiber is prone to skid off fabric face and becomes fuds fuddled.Simultaneously, rabbit fur fibre all has pulp cavity, and brute force is lower, and easy the generation ruptured and fallen hair in wearing washing process.In weaving processing, in order to keep the style of rabbit hair product soft fluffy, yarn twist is generally less, and fabric construction is pine, also can make rabbit hair fabric fall hair easily.
At present, solve the research that the rabbit hair falls mao problem and mainly contain three directions: the modification of rabbit fur fibre, the back arrangement of the improvement of rabbit hair textile technology and rabbit hair fabric.Wherein, the afterfinish method of rabbit hair fabric mainly is to design suitable rabbit hair losing fibre preventing finishing agent (abbreviation finishing agent).Generally contain film-formable polymer in the finishing agent, after the arrangement, polymer deposition is in the rabbit fur fibre surface; Has cancellated polymer film in the formation of rabbit fur fibre surface; Increased interfibrous sticking point, reduced the generation of rabbit hair slippage and surface floating hair, gross weight is descended.The fibre damage that this type arrangement can effectively avoid fibre modification to bring, but maybe the style and the feel of rabbit hair fabric be impacted.
Polyurethane and acrylic resin are two types of different polymer, do not contain formaldehyde but all have, preferably characteristics such as film forming and elasticity.Take different reaction monomers or reactant and different synthesis technique, can produce the polyurethane and the acrylic resin product of different performance, and be widely used in the back arrangement of textiles as the different finishing agent of function.For example, the aqueous polyurethane of introducing specific groups can be made into the finishing agent of fire resistant flame retardant, also can be used as the anti-piping compound, Antisepticize and mildew preventive, chemically-resistant finishing agent of wool product etc.Acrylic resin is mainly used in the coating of textiles, bonding, thickening and aspect such as stiffening, also can finishing agent be used for improving the performances such as antistatic and anti-fluffing and anti-pilling of fabric.
