Abstract
The present invention relates to a kind of smooth memory knit fabric and preparation method thereof, comprise skin and internal layer, described skin is made up of super fine denier polyester fiber, and described internal layer is made up of Modal staple-yarns line and polyurethane fibre long filament; Its preparation method, comprising: (1), after structural design, adopts weft-knitted one side spininess road principle of readjustment, restructuring, consolidation and improvement to be that 28 ~ 32G weaves apart from pin type weft knitting plane No., obtains knit fabric; (2) by above-mentioned knit fabric through pre-setting, pre-treatment, dye polyester fiber, resisdye Modal fiber, fixation, washing, multiple sizing, finally dry.Fabric of the present invention has high-elastic, fine and smooth, smooth, water-absorbing fast-drying, antibacterial and deodorizing, wash after not yielding, wear the light feature such as comfortable, and overcome that traditional fabric feel is poor, cloth cover sends out wrinkle, wet guilding not enough, the easy shortcoming such as smelly.
Description
Technical field
The invention belongs to knit fabric and preparation field thereof, particularly a kind of smooth memory knit fabric and preparation method.
Background technology
Current conventional pure cotton fabric, real silk fabric, linen and conventional synthetic fabrics are utilized widely by people.But in use, pure cotton fabric easily grows a large amount of bacterium, and shape-retaining ability is poor; There is maintenance difficulty in real silk fabric, not easily nursing, fugitive color, the shortcoming such as expensive, and linen exists wrinkle resistance difference, its fiber is larger than bending stiffness, to problems such as skin urtication sense are strong; Its drawback as close-fitting fabric also will be more and more obvious.
Patent name " bamboo fibre tencel blended fabric " (application number: 201110098965, publication number: CN102747497A, publication date: 2012.10.24).Disclose that a kind of many components regenerated fiber is mixed knits shuttle-woven fabric.Patent name " functional fabric that Pai Site fiber and milk protein fiber interweave " (application number: 201220065464, publication number: CN202466060, publication date: 2012.10.03), disclose that a kind of many components chemical fibre is mixed knits shuttle-woven fabric.Two kinds of fabrics all have certain functional and comfortableness, but make its elasticity and comfortableness be subject to certain restriction because of its factor of weaving.
According to China Textile Information Center's statistics, along with the change of people's life idea, knit product is with its comfortable feel, the feature such as outward appearance is graceful, style is exquisite, and being more and more subject to people likes, product value improves 6% in nearly 3 years.So the close-fitting fabric developing the feature such as comfortable, ventilative, antibacterial will have great market.
