| With the rapid development of contemporary society,the efficient and fast pace of life has brought people a variety of social and mental stress and many other negative effects,most people are in the physical and mental sub-health state.Home textile and bedding products accompany people’s life time 1/3,and close clothing is the modern indispensable textile and clothing products.soft and comfortable lingerie and home woven bedding can effectively relieve people’s physical and psychological anxiety and discomfort.This topic changes the fabric softness by changing the yarn fabric structure,The super soft yarn and fabric based on Pylon partner spinning were developed by blending Pylon fiber and long staple cotton fiber with water soluble temperature of 80℃.The spinnability of the super soft fabric and the reasonableness of the spinning process parameters were determined by the basic properties of the blended yarn,such as strength and elongation,hairiness and slippage inequality,Select soft and comfortable and breathable weft plain knitting fabric for knitting,explore and analyze the best dedimensivity process.A super soft fabric based on vinylon was developed by dedimensioning the fabric,The basic performance was tested,Combined with the super soft quality rating and the softness was tested from three dimensions: physical,visual and tactile.The fabrics with excellent softness in three dimensions were obtained by the grey near optimal comprehensive evaluation method.This paper discusses the optimal spinning process of water-soluble PVA/cotton spinning,This paper discusses the optimal spinning process,TWater soluble vinylon fiber/long staple cotton blending ratio was designed to be 5/95,10/90,15/85,20/80 fiber content ratio,14.6tex and 19.6tex linear density of two yarns,Eight blended yarns with a twist factor of 300.The basic properties of yarn are tested,The hairiness index of the eight yarns was all low,8~9mm long harmful hair is almost not,The uniformity of strip is good,All were below 15%,The average breaking strength of yarn with a linear density of 14.6tex is 13.7c N/dtex,The average breaking strength of yarn with 19.6tex density is 14.19 c N/dtex.All the performance requirements of the eight yarns meet the test standards after the yarn performance test,which verifies the spinnability of water-soluble Pylon fiber and cotton fiber,and meets the requirements of weaving and dimensionality reduction.Choose the weft plain stitch with better softness,16 needle flat knitting machine,The total number of stitches is 500 stitches and the 50 cm width is knitted.The effect of water bath heating dedimensionality and ultrasonic dedimensionality on the dedimensionality rate of fabric at different temperatures was discussed.The experimental results show that,The ultrasonic dedimensionality of 45 k Hz at 75℃ is the best.The bursting strength,thickness,air permeability and warmth retention of eight kinds of fabrics before and after dedimensification were tested and analyzed,After dedimensioning,the dedimensioning strength of fabric decreases,The thickness reduction,The air permeability and warmth retention have been improved,However,the basic properties of all fabrics meet the relevant standards.The fabric relative feel tester(magic instrument)was used to evaluate the super soft quality of the fabric,Light fabrics with softness≥83(7 stars)were rated as super soft fabrics,Fabric A1(14.6 Tex,blend ratio 5/95)and fabric B1(19.6 Tex,blending ratio of 5/95)did not meet the standard of super soft fabric,The other 6 fabrics all reached the super soft standard.The softness of the fabric was tested in three dimensions,including rigidity and flexibility,drape and FTT touch,Combined with the super soft grade evaluation and the grey near optimal comprehensive evaluation method was used to order the super soft comprehensive evaluation of fabrics as follows:A2>A4>A3>B4>B2>B3,The fabric has the best softness when its linear density is14.6tex and water-soluble PVA ratio is 10%. |
