The purpose of the present invention is to obtain a spunbonded nonwoven fabric, which comprises a single-component polyester-based fibers, having a high basis weight and a high rigidity by embossing, which is difficult to attain in the conventional art. Further, the present invention provides a filter base material having excellent pleatability, pleat retention property and durability, and a filter using thereof. The present spunbonded nonwoven fabric is obtained by subjecting a deposited fiber assembly to a thermocompression bonding by embossing with a pair of an embossing roll and a flat metal roll, and has a basis weight of 150 to 400 g / m2, a longitudinal bending repulsion of 20 to 60 mN and a longitudinal tensile strength of 400 N / 5 cm or more.

The invention relates to a preparation method of cylinder adhesive for crepe paper. The existing cylinder adhesive generally has defects such as poor film forming performance, poor film forming elasticity and poor remoistening performance and the like. By utilizing a water-soluble macromolecular polymer in a water phase, by adding a cross-linking agent and a plasticizer, the cylinder adhesive is prepared by virtue of local cross-linking of macromolecules and the compounding of the plasticizer. The cylinder adhesive prepared by the invention is stable in performance, has good adhesive force andfilm forming performance, can adjust the remoistening performance and softness of a film and can well improve the wrinkling performance of the crepe paper.

The invention discloses hygroscopic and sweat releasing knitted fabric with a shape memory function and a processing method thereof. The fabric comprises a dual-face dual-layer twill cloth structure, wherein a face, that is to say, an outer layer is a cotton bale shape memory function covering yarn, and an opposite face, that is to say, an inner layer is a shape memory polyester fiber. The processing method of the fabric comprises the following steps: the outer-layer structure is selected from the cotton bale shape memory function covering yarn, and the inner-layer structure is selected from the shape memory polyester fiber, knitting is carried out on a dual-face knitted circular knitting machine, and ribs are opposite: two upper needles with one low needle and one high needle are arranged, and four lower needles 1 2 3 4 are arranged; and a knitting process is a cycle including 16 paths. The fabric has a shape memory function and good hygroscopic and sweat releasing performance of a cotton natural fiber. Clothes made by the fabric is not supported by external force, so that any shapes can be independent kept and any drapes can be represented, after lightly whisking by a hand, the smooth state is completely restored without any folds, and the shape is kept and the fabric has permanence.

The invention relates to a PTT (poly(trimethylene terephthalate)) memory fabric, in particular to a PTT memory fabric production process. The production process comprises the following steps of: batch warping, starching, shaft combining, leasing, looming healding, weaving, pretreatment of dying and finishing, alkali quantity decreasing, dying, waterproof processing and thermal forming. The fabrichas unique memory function and comfortable hand feel, the performance of smoothing by touching the fabric enables the product to achieve an effect of totally ironing free, and favorable draping effect and recovery capability enable the fabric to become one of fashionable functional fabrics. Fibers of the fabric are completely biodegradable under certain condition and the fabric is an environmental-protection and green product.

A method for manufacturing a creped fiber web is provided and includes providing a rotating cylindrical dryer surface, providing a creping adhesive composition or coating package having a pH boosted at least 0.5 pH units relative to its original base formulation pH in the range of from about 4.5 to about 9, for chemically setting a crosslinkable polymer component at least in part before applying the creping adhesive composition to the rotating cylindrical dryer surface to provide an adhesive dryer surface on which a fiber web can be transferred, dried, and creped.

The invention relates to a woolen knitting pleat clothing preparation method. The method comprises steps of: (1) preparing a solution, namely preparing the solution which contains 30-50g / L of an antifelting addition agent, 1-3g / L of a wetting agent and 10-20g / L of a reducing agent and has a pH value of 6.5-7.5; (2) soaking woolen knitting clothing into the solution to be completely soaked, and then spinning the clothing to be dry until the liquid content of the clothing is 65-90%; (3) carrying out pleat treatment on the clothing treated in step (2); (4) washing the pleat clothing with water for 5-15 minutes, then soaking the clothing in a solution containing 2.0% of hydrogen peroxide at 40-50 DEG C for 15-25 minutes, and finally, washing and airing the clothing. The preparation method is simple to operate, and the woolen knitting clothing has a good pleat effect.

The invention provides a processing method for real silk crepe-de-chine shell fabric. The processing method for the real silk crepe-de-chine shell fabric utilizes real silk green body raw materials to serve as raw materials, and the whole processing flow comprises the steps that (1) pre-processing is carried out; (2) degumming and white refining are carried out on the processed green body raw materials; cold water tank soaking is carried out, and the green body raw materials are placed in a cold water tank with the water temperature ranging from 15 DEG C to 30 DEG C and soaked for 40-60 minutes; primary refining process is carried out, 20-25 kg of dispersing agents, 20-25 kg of sodium carbonate, 4-6 kg of sodium silication and 1-1.5 kg of sodium hydrosulfite are added into a primary refined tank containing 5 tons of water, the water temperature rises from 80-85 DEG C to 100 DEG C, and refining is carried out again for 40-50 minutes; secondary refining process is carried out, 8-10 kg of the dispersing agents, 2-2.5 kg of the sodium carbonate, 4-6 kg of the sodium silication and 0.5-1 kg of sodium hydrosulfite are added into a secondary refined tank containing 5 tons of water, the water temperature is kept at 100 DEG C and refining is carried out for 30-40 minutes; (4) coiling is carried out, tension-free coiling is carried out by a loose type coiling machine; (5) arranging is carried out, drying and stretching are carried out by a tension-free carpet machine and a stretching machine, and then the real silk crepe-de-chine shell fabric with the shrinkage rate reaching to 6%-8% is obtained. According to the real silk crepe-de-chine shell fabric obtained by the processing method, the shrinkage rate can reach to 6%-8%, and the whiteness is good.
