Description
Technical field
The present invention relates to a textile fabric production technology field, particularly the production technology of a kind of day silk milk fibre man textile fabric.
Background technology
Milk fibre since coming out with its good physical mechanical performance, skin compatibility extremely people is paid close attention to, but also have simultaneously very important defective: heat resistance, acid-proof alkaline are poor, especially alkali resistance is poor, coefficient of friction is large, electrostatic phenomenon is serious, and these factors are all restricting the prodution and development of milk protein fiber product.Therefore, in the process of development, milk fibre and silk fiber blended, the advantage that not only can give prominence to milk fibre is maximized favourable factors and minimized unfavourable ones, and can develop again the product of different style simultaneously, reduces production costs.It silk (Tencel) is after adopting the N-methoxyl group morpholine aqueous solution dissolving cellulos of (being called for short NMMO), carry out a kind of high wet modulus regenerated celulose fibre that wet spinning is produced, more comfortable than cotton, sense of touch and texture are all like silk, but shrink-proof distortion, variable color are produced and are carried out in closed system, and the rate of recovery of organic solvent NMMO can reach more than 99%, environmental sound, therefore a day silk is the environmental protection fiber.It silk, blended by milk fibre uses, and when giving fabric sofetening, can improve the wrinkle resistance of fabric, and the DIMENSIONAL STABILITY of product also is improved.Its soft feel, beautiful dangle, beautiful outward appearance and suitable elasticity effect determined that this product can be widely used in the household textiles field of most of cotton spinnings, knitwear.
A kind of milk protein fiber, chemical fibre, cashmere blended yarn and knitted fabric thereof and production method (application number: 200610053965.2), adopt milk fibre 35-50%, PPT35-50%, goat cashmere 10-15%, all be spun into the twist behind the even hair and be 860-880T/M, S twist with the fingers to one-ply yarn, then being plied to the twist is that 620-650T/M, number are 42-60N/2, Z twist with the fingers to bifilar knitting blended yarn, use above-mentioned knitting blended yarn to be made into the count coefficient by 12-16 knit type knitting machine and be the knitted fabric of 1.25-1.35mm.tex.But in milk fibre spinning smooth surface, filoplume is many, easy glide, and the shortcoming aspect such as electrostatic phenomenon is serious does not have the breakthrough of essence, can't satisfy people to the household textiles smooth and bright surface, the demand of the style characteristic that imitative silk sense is strong.
Summary of the invention
The object of the present invention is to provide the production technology of a kind of day silk milk fibre man textile fabric, simple to operate, technological process is shortened, and has reduced energy consumption, has again sustainability, complies with the low-carbon economy trend, has a extensive future.
The technical solution adopted for the present invention to solve the technical problems is:
The production technology of a kind of day silk milk fibre man textile fabric, described day silk milk fibre man textile fabric, is weaved through blending by the weight proportion of tencel fiber: milk fibre=30-35:70-65, dyeing and finishing and getting; Described tencel fiber specification is fineness 1.4-1.5dtex, length 38-40mm; Described milk fibre specification is fineness 1.4-1.5dtex, length 38-40mm.
One of fiber that it silk is present the most environmental protection, the rate of recovery of employed organic solvent NMMO can reach more than 99% in its production process, substantially environment is produced and pollutes; Milk fibre is mainly take milk as raw material, and raw material sources are abundant, do not use formaldehyde azo auxiliary agent or raw material, and the fiber content of formaldehyde is zero, has sustainability and the feature of environmental protection, complies with the low-carbon economy trend.The present invention optimizes a day silk blended by milk fibre ratio, the advantage of the multiple fiber of family's textile fabric collection, and it is soft smooth that fabric is had, and gloss is beautiful, moisture absorption, close skin is warming, high-strength wearable, ventilative comfortable characteristics make no matter it is at aesthetic property or snugness of fit, functional, and are all more perfect.The present invention improves to some extent and innovates in production technology, for two kinds of fiber blends, weave, dyeing and finishing provides effective technique, for society provides a kind of desirable high-grade product, has preferably Social benefit and economic benefit.
