Abstract
Polypropylene fibers have excellent heat insulation performance, but also have the defect of incapability of withstanding temperatures over 120 DEG C, so that fabrics containing polypropylene fibers cannot be added with traditional elastic materials such as spandex, and the fabrics containing polypropylene lack elasticity and stability, leading to great limitation on the application of the fabrics containing polypropylene in the field of knitted underwear. The invention aims to perform the brand new attempt of weaving gray cloth by using polypropylene yarns (or polypropylene-containing blended yarns) in cooperation with polyolefin elastic yarns which can be sized at a low temperature, a fabric is made through a low-temperature dyeing and finishing process, and the fabric is made by combining polypropylene and the polyolefin elastic yarns. By adopting the fabric developed by the invention, the heat insulation advantage of polypropylene can be brought into full play, the defect of non-temperature resistance of polypropylene is overcome, a novel fabric having high elasticity, high elastic recovery rate, stable size and excellent heat insulation performance is developed, and the application range of polypropylene and the polyolefin elastic fibers in the field of heat insulation underwear can be expanded.
Description
Technical field
The present invention relates to a kind of manufacture method and postfinishing process of the special frivolous thermal fabric of knitted elastic, it is characterized in that adopting polyolefin elastic fibers and polypropylene staple fibre spun yarn or interweave containing the mixed yarn of polypropylene fibre, and adopt low temperature dyeing and postfinishing process, thereby make to invent the be up to state standards requirement of (the national sector standard FZ/T73022-2004 of knitting thermal underwear) defined of comfortable, the warming rate of made fabric dimensionally stable, elasticity by this: warming rate is more than 30%.
Background technology
Along with the progress in epoch, people have also proposed more and more to underwear, more and more higher requirement, and especially the requirement of winter warming underwear having been proposed to new challenge-not only frivolous but also warming cold-proof underwear has strong consumer demand and wide market prospects.
On market in the warming characteristic of main fiber, the warmth retention property of polypropylene fibre is very outstanding (by relatively finding, the thermal property of polypropylene fibre is apparently higher than wool, acrylic, acrylic fibers, the fibers such as terylene), but polypropylene fibre can not withstand high temperatures, can not tolerate 120 DEG C of above temperature containing the fabric of polypropylene fiber, so seriously restricted the application of polypropylene fiber aspect garment material, limit the performance of the warming advantage of polypropylene fibre, the sizing that contains the fabric of polypropylene fibre is a fatal defect, especially cold-proof underwear need to add elastic filament conventionally to reach elasticity, comfortable, next to the skin and warming effect.
Spandex is a kind of traditional elastic filament, the setting temperature of the common fabric containing spandex is between 180 DEG C-200 DEG C, even if the setting temperature of state-of-the art low temperature spandex is also more than 170 DEG C, because the difference of polypropylene fibre heat resistance, so cannot be adding polyurethane elastic filament containing in the fabric of polypropylene fibre.
If by force polypropylene fibre is made together with spandex to fabric, do 120 DEG C of low temperature or the sizing of following temperature (exceedes this temperature according to the requirement of polypropylene fibre, polypropylene fibre can melt), the fabric size of working it out extremely unstable (shrinkage is in 15%-30% left and right conventionally), cannot reach requirement or the standard of clothing fabric completely.
Knitting thermal underwear in winter on market now, material is taking polyester flannel+cotton as main, small part fabric has added a certain proportion of wool, cashmere etc., more than 30% standard of warming rate requiring in order to arrive the national standard of warming rate, and the grammes per square metre of knitting thermal underwear must be at 280-300g/m conventionally
2above.
For the cold-proof dress ornament under part open air, mountain-climbing and harsh climate condition, requirement to warming rate is higher, because the restriction of warming rate, adopt insulated cold wear that traditional material makes or winter warming underwear do thicker and thicker, some warming rate requires the grammes per square metre arrival 400-500g/m2 of more than 40% warming underwear; Some warming rate requires the grammes per square metre of more than 50% warming underwear to arrive 500-800g/m2, and reality has been changed in quality into wadded jacket cotton-padded trousers, has been no longer the concept of the underwear of understanding conventionally, also greatly differs from each other from consumer's attractive in appearance, warming demand.
Present stage, because do not have the elastic filament of suitable ultralow temperature sizing can coordinate the low temperature process requirement of polypropylene fibre, so be difficult to produce the fabric containing polypropylene fibre raw material that meets underwear or the cold-proof underwear market demand, object of the present invention is exactly will be by adding special polyolefin elastic fiber material, adopt the postfinishing process of special low-temperature environment-friendly, produce that one accords with the demands of the market, the particularly preferred knitting frivolous thermal fabric of warmth retention property.
Summary of the invention
The object of the invention is to polypropylene staple fibre spun yarn to combine and weave embryo cloth with special polyolefin elastic fibers, then by adopt the postfinishing process of low-temperature environment-friendly, produce accord with the demands of the market, give full play to polypropylene fibre excellence warmth retention property, have the knitting frivolous thermal fabric of good elasticity and elastic recovery rate.
