Apparatus and method for encoding binary shape signals in shape coding technique

PURPOSE: A system and a method for encoding a binary form signal are provided to arithmetic-encode a binary form signal in unit of one pixel or in unit of predetermined PxP sub-block on the basis of the quantity of generation of bits after encoding. CONSTITUTION: When binary pixel values in a binary form signal extracted from a video frame are arithmetic-encoded, binary pixel values in a corresponding binary alpha block are encoded in unit of one pixel and in unit of PxP sub-block. The number of bits after the encoding is calculated. Encoded data having smaller number of bits is selected as final output data, thereby remarkably improving encoding efficiency of the binary form signal.

Hydrophobically dressed fiber material and method for producing layer of dressed material

FIELD: textile, paper. SUBSTANCE: invention relates to a multi-layer cardboard having at least one middle layer formed from such a fibrous web, as well as to the use of a thermosensitive surfactant in the mentioned methods and products. According to the method of microfibrillated cellulose (MFC) and a hydrophobically dressed agent, a foam with water and a thermosensitive surfactant are obtained. The foam is fed to the forming fabric of the papermaking or cardboard machine, dehydrated by sucking air through the forming fabric and dried to form a web of paper or cardboard. In order to prevent gradual degradation of the hydrophobically dressed agent, the hydrophilic functionality of the surfactant is eliminated by heating. EFFECT: inclusion of pulp with fibres longer than fibers of MFC provides high bulk, combined with a high value of ply bond by Scott, providing improved tensile strength in dry and wet state for paper and cardboard products. 24 cl, 1 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 635 615 C2 (51) МПК D21H 21/24 (2006.01) D21H 21/56 (2006.01) D21H 11/18 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2014146501, 25.04.2013 (24) Дата начала отсчета срока действия патента: 25.04.2013 Дата регистрации: (72) Автор(ы): ХАИСКАНЕН Исто (FI), КИННУНЕН Карита (FI), ХЬЕЛЬТ Туомо (FI) Приоритет(ы): (30) Конвенционный приоритет: (56) Список документов, цитированных в отчете о поиске: US 3839142 A, 01.10.1974.

The resin component is selected from polyamidoamine-epigalohydrin (PAE) resins, polydiisocyanate resins, urea-formaldehyde (UF) resins, melamine-formaldehyde (MF) resins, polydiisocyanate (DI) resins and mixtures thereof. The sizing agent is selected from an alkylene ketene dimer (AKD), an alkyl succinic anhydride (ASA), a rosin derivative, or a mixture thereof. Moreover, the amount of fibers that have never been dried in the pulp is at least 15 wt % based on the total dry weight of the pulp. EFFECT: invention provides increased moisture resistance, decreased moisture expansion and increased hydrophobicity of a paper or cardboard product. 18 cl, 5 tbl, 1 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) (19) RU (51) МПК D21H 17/52 D21H 17/55 D21H 17/57 D21H 17/62 D21H 21/16 D21H 21/18 D21H 21/20 (11) (13) 2 746 735 C2 (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК D21H 17/52 (2020.08); D21H 17/55 (2020.08); D21H 17/57 (2020.08); D21H 17/62 (2020.08); D21H 21/16 (2020.08); D21H 21/18 (2020.08); D21H 21/20 (2020.08) (21)(22) Заявка: 2019109943, 19.09.2017 19.09.2017 Дата регистрации: (73) Патентообладатель(и): КЕМИРА ОЙЙ (FI) 19.04.2021 30.09.2016 CN 201610922522.6; 19.10.2016 FI 20165795 (43) Дата публикации заявки: 30.10.2020 Бюл. № 31 (56) Список документов, цитированных в отчете о поиске: WO 2015167440 A1, 05.11.2015.

A method of controlling retention and an intermediate product used in the method

본 발명은 제지 공정에서 성형 직물에 대한 보류도를 조절하는 방법, 이 방법에 사용되기 위한 중간 생성물 및 중간 생성물용 물질의 용도에 관한 것이다. 중간 생성물을 만들기 위해, 제지용의 주요 섬유 현탁액의 섬유의 비표면적보다 큰 비표면적을 갖는 마이크로피브릴화 셀룰로스(MFC)와 같은 미세 셀룰로스 섬유의 슬러리에 적어도 1종의 제지용 화학약품을 첨가함으로써, 제지용 화학약품을 상기 미세 셀룰로스 섬유 상에 흡착시킨다. 이어서 이 중간 생성물을 현탁액이 초지기의 헤드박스로부터 성형 직물에 공급되기 전에 주요 섬유 현탁액에 혼입시킨다. 여러가지 화학약품들 간의 상호반응을 방지하기 위해, 중간 생성물 첨가 전 또는 첨가 후에, 다른 제지용 화학약품들을 섬유 현탁액에 첨가할 수 있다. 본 발명에 의해, 일반적으로 보류도 증가가 가능하며 제지용 화학약품들의 보류도의 개별적 및/또는 상호 연관적인 조절을 더욱 개선시키는 것이 가능하다. The present invention relates to a method for controlling retention to a forming fabric in a papermaking process, to the use of the intermediate and intermediate products for use in the process. By adding at least one papermaking chemical to a slurry of microcellulose fibers, such as microfibrillated cellulose (MFC), having a specific surface area greater than the specific surface area of the fibers of the primary fiber suspension for papermaking, , And the papermaking chemical is adsorbed onto the microcellulose fibers. This intermediate is then incorporated into the primary fiber suspension before the suspension is fed from the headbox of the paper machine to the forming fabric. To prevent the interaction between the various chemicals, other papermaking chemicals may be added to the fiber suspension before or after the addition of the intermediate product. With the present invention it is generally possible to increase the retention and further improve the individual and / or correlated control of the retention of the papermaking chemicals.

Sizing composition

FIELD: stabilized dispersions. SUBSTANCE: invention relates to emulsification and colloidal stabilization of emulsions and dispersions of hydrophobic phases in aqueous phases using a coacervate. In particular, stable emulsified or dispersed composition of invention, including hydrophobic and aqueous phases, is stabilized by cationic colloidal coacervate stabilizer including anionic and cationic components in a proportion ensuring zeta potential of the composition to be at least 20 mV. Preferred hydrophobic phase is non-colophony reactive or non-reactive sizing substance, although employment of coacervate allows stable emulsions or dispersions of mixtures of colophony and non-colophony sizing substances to be obtained.
