preparation example Construction

[0018] The preparation method of the anti-drilling fleece fabric includes the following steps in order: warping → sizing → weaving → normal temperature stacking → first hot water washing → refining, bleaching, desizing → second hot water washing → softness and shaping → Anti-drilling down calendering treatment→normal temperature pre-shrinking, the anti-drilling down calendering treatment process is to make the polylactic acid fiber form an anti-drilling down film layer on the reverse side of the fabric through hot pressing.

[0019] Polylactic acid fiber has excellent biocompatibility and biodegradability. Its fiber strength is slightly lower than that of polyester fiber, its resilience performance is good, and its initial modulus is smaller than that of polyester fiber. Therefore, polylactic acid fiber fabrics are softer and more skin-friendly than polyester fibers. , while polylactic acid fiber has good antibacterial function. The combination of polylactic acid and Tencel fi...

Embodiment 1

[0029] The warp yarn of the fabric is 40S tencel, and the weft yarn of the fabric is 150D polylactic acid filament, which is composed of 144 single fibers. The fabric weaving specification is 40S*150D / 150*120, and the fabric weave is five pieces of three-flying satin weave.

[0030] Gray cloth washing process conditions temperature is 95 ℃, time is 20min. In the refining, bleaching and desizing processes, the technological parameters are 5 g / L of soda ash, 10 g / L of hydrogen peroxide, 5 g / L of chelating agent, and 5 g / L of hydrogen peroxide stabilizer.

[0031] After the pre-treatment of the fabric, soft setting is carried out, wherein the setting temperature is 90°C and the time is 3 minutes.

[0032] In order to achieve the anti-drilling performance of the fabric, the reverse side of the fabric is hot-pressed by using a combination of metal rollers and rubber rollers. The temperature is 120°C, the speed is 30m / min, and the pressure is 6kg.

Embodiment 2

[0035]The warp yarn of the fabric is 80S tencel, and the weft yarn of the fabric is 50D polylactic acid filament, which is composed of 48 single fibers. The fabric weaving specification is 80S*50D / 230*180, and the fabric weave is five pieces of three-flying satin weave. Gray cloth washing process conditions temperature is 80 ℃, time is 10min. The technological parameters in the refining, bleaching and desizing processes are 3 g / L of soda ash, 8 g / L of hydrogen peroxide, 4 g / L of chelating agent, and 3 g / L of hydrogen peroxide stabilizer.

[0036] After the pre-treatment of the fabric, soft setting is carried out, wherein the setting temperature is 80°C and the time is 1 min.

[0037] In order to achieve the anti-drilling performance of the fabric, the reverse side of the fabric is hot-pressed by using a combination of metal rollers and rubber rollers. The temperature is 110°C, the speed is 40m / min, and the pressure is 4kg.

Abstract

The invention provides a downproof fabric containing polylactic acid fibers. The downproof fabric is formed by interweaving warp and weft. Tencel fibers are adopted in the warp direction, polylactic acid fiber low stretch yarn is adopted in the weft direction, through the five-piece three-fly warp face satin weave, the tencel fibers are shown on the surface of the fabric, the polylactic acid fibers are shown on the reverse face of the fabric, the reverse face of the fabric is subjected to downproof hot pressing, the polylactic acid fibers on the surface of the fabric generate slight heat shrinkage and plastic deformation, a downproof thin film is formed, and the polylactic acid fibers not suffering from heating deformation in the middle are interwoven with tencel to form a middle layer of the downproof fabric. The tencel fibers with smooth touch sense are arranged on the surface of the fabric, the good fluffy softness of the fabric is achieved through the middle interweaving layer of the tencel and polylactic acid, and the polylactic acid thin film layer on the reverse face achieves the purpose of preventing down from getting out. Through reasonable fabric design and process parameter formulation, finally the downproof fabric with antistatic performance, bacteriostatic performance and biodegradability is obtained.

Description

technical field [0001] The invention belongs to the technical field of household textiles, and in particular relates to an anti-drilling fleece fabric containing polylactic acid fibers. Background technique [0002] In recent years, environmental problems such as climate warming, poor air quality, and water pollution have become increasingly prominent, and people are paying more and more attention to ecological and environmental issues. Among the bedding fabrics, the anti-drilling down fabric is specially used as a duvet fabric. In order to prevent the down from getting out of the fabric, it usually requires a higher tightness, and the fabric needs to be coated or added with a windproof finishing agent. [0003] At present, the mainstream varieties used for duvet fabrics are cotton, polyester-cotton, and polyester. Cotton fiber is easier to absorb moisture and expand than polyester fiber, so the durability of anti-drilling fleece is slightly worse; polyester fiber has bette...
