Abstract
The present invention relates to a method which uses the warp yarns of some cotton, nylons and thermal-resistant fiber union yarns to prepare heat-resisting and durability woven fabrics.
Description
The present invention relates to a kind of thermodurable textile with high-durability and good fabric aesthetic property.This fabric is made by the blended yarn of cotton, nylon and heatproof organic fiber.
The ABRASION RESISTANCE of the fabric that is made by the blended yarn of cotton fiber and heat-resisting thermosetting fibre when with soft thing mantle friction, only slightly is better than the ABRASION RESISTANCE of all-cotton fabric.
The welder wears cotton close-fitting work pants usually, but Mars damages when scalding the hole soon, and will wear out during soft thing surface abrasion at pocket and cuff place.The coat of numerous species particularly is exposed to the work clothing in heat and the Mars, all needs cotton blended fabric that high-fire resistance, good aesthetic property and soft thing surface abrasion resistance are highly arranged.The fabric that is made by the blended yarn of cotton and nylon has good soft thing surface abrasion resistance, but heat resistance and COTTON FABRIC roughly the same not even as.The soft thing surface abrasion resistance of the fabric that is made by the blended yarn of cotton, polyester and heat resistance fiber [for example PPTA (PPD-T)] is roughly the same with the fabric that cotton and PPD-T blended yarn make, but is lower than the polyester/cotton fabric.
The invention provides the fabric that is suitable for having good heat resistance, durability and fabric aesthetic property, this fabric comprises the spun-blend as warp thread, and this blended yarn comprises: 15～50%, and be preferably 15～35% limited oxygen indexs (LOI) and be at least 25 heat resistance fiber; 5～20%, be preferably 10～15% fatty polyamide fibers; At least 30%, be preferably at least 50% cotton fiber.The novel fabric that contains this class warp thread is made up of 8-50% heat resistance fiber, 3～25% nylon fibers and 30～89% cotton fibers.Percentage composition is a weight percentage.
Staple fibre used herein is the fabric fibre that line density is fit to wear coat, and promptly its line density is less than the 10dtex/ fiber, preferably less than the 5dtex/ fiber.Be more preferably the about 1～3dtex/ fiber of line density, the about 1.9～6.3cm(0.75 of length～2.5 inches) fiber.Good especially for fabric aesthetic property and processability crimped fibre.
The method of making fabric comprises that at first preparation contains the step of the blended yarn of 15～50% heat-resisting staple fibres, 5～20% fatty polyamides (nylon) staple fibre and at least 30% cotton.With the blended yarn spun yarn, be that warp thread is made into fabric with this yarn.When selecting weft yarn, be limited in the nylon in the fabric 3～25% of fiber content, heat resistance fiber is limited in 8～50%, and cotton is limited in 30～89%.
For reaching the result who needs, the appropriate level that keeps three fibrids is important condition.Heat resistance fiber causes very little that fabric splits very soon when being exposed to flame and Mars; The excessive good aesthetic property that then can lose cotton goods of heat resistance fiber.Nylon in the warp thread is that the soft thing surface abrasion of protection is necessary, but too many will make the fabric hardening, and can lose drapability when fabric is of short duration when being exposed to about 300 ℃ temperature.Cotton fiber can provide nylon and heat-resistant fiber blended yarn the soft hand feeling and the hygroscopicity that can not provide, therefore can produce fabric comfortable and easy to wear.Cotton fiber is being exposed to heat and during flame, because it is adhered to one another that fiber does not take place, can also forming pliable and tough charcoal layer, so tends to keep original position and excellent protection is provided.
Be that a small amount of nylon fiber can improve the soft thing surface abrasion resistance of novel fabric greatly in the warp thread unexpectedly, and can be when fabric is not exposed to the temperature that is higher than the nylon fusing point, significantly sacrificing flexibility and drapability.
Shown in following example 1-3, compare with control fabric A, B and C, when a small amount of nylon is added in 3 * 1 twill warp thread, Tai Bo (Taber) ABRASION RESISTANCE is improved greatly.Seen in example 2, only add 10% nylon fiber in the warp thread, just be enough to make the ABRASION RESISTANCE comparison to double many according to fabric C.These examples also show, nylon content can reach the twice of all-cotton fabric (control fabric C) up to 20% and contain the fabric of 15%PPD-T at least stands flame under load time in the warp thread.These examples also show, contain the fabric of cotton, nylon and PPD-T fiber, even be heated to 300 ℃, also can keep good drapability, as shown in table 1,30% nylon is arranged in the warp thread, weft yarn becomes very stiff when to be that the control fabric D of 100% cotton is of short duration be exposed to 300 ℃.This has illustrated and has kept the low importance of nylon content in the warp thread.
Fiber can be with some kinds of different spinning method spun yarns, and these methods comprise (but being not limited only to) ring spinning, Jet Stream spinning and friction spun yarn.
Nylon 66 is preferred fatty polyamides, but other fatty polyamides such as nylon 6 have similarly heat-resisting and fatigue behaviour, also can use satisfactorily.
Used in addition term " heat resistance fiber " is meant and contains carbon and hydrogen, also can contain for example polymer short fiber of oxygen and nitrogen of other elements, and its heat-resistant time is at least 0.018 second/g/m
2(0.6 second/oz/yd
2).
An example that is used for heat resistance fiber of the present invention is PPTA (PPD-T) staple fibre (LOI28,0.04 second/g/m of heat-resistant time
